The so-called High Seas Treaty is a legal framework for the protection of marine biodiversity and responsible and equitable use of resources of areas beyond national jurisdiction (BBJN). Its draft, published on the 5th of March 2023, is the outcome of two decades of negotiations, and is part of the international effort to protect a third of the world’s biodiversity by 2030.
An unwavering dedication to the protection and conservation of biodiversity will be required to see the firm landing of this hopeful step.
On this occasion, we look back at some impactful studies published in our journals that have made waves, hopefully in the right direction towards impactful conservation measures and actions.
Following President Barack Obama’s expansion of the largest permanent Marine Protected Area on Earth (Papahānaumokuākea Marine National Monument) in 2016, a new species of coral-reef fish was named in his honour. The fish is the only known coral-reef species to be endemic to the Monument, and, despite its small size, it carries wide-reaching cultural and political significance as a reminder of how politics go hand in hand with science.

Other studies from our flagship zoology journal ZooKeys have focused on the benthic megafauna and abyssal fauna of the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean.
The Clarion-Clipperton Zone, managed by the International Seabed Authority, has been targeted by deep-sea mining interests. In the context of heightened concern over potential biodiversity loss, scientific research is crucial for informing policy-makers and the general public about the risks and outcomes of such initiatives.

The rich biodiversity of the deep sea has also been documented in big-scale taxonomic inventories and checklists in the Biodiversity Data Journal.

Going forward, the expansion of Marine Protected Areas should also ensure the implementation of policies for the methods of resource extraction and their equitable sharing and use among the world’s nations.
Over the next few years, we hope to see an ever increasing interest in biodiversity conservation - from the general public, stakeholders and policy makers, and, of course, research institutions.
We need to love what we protect in order to be able to protect it.

OpenBiodiv is a biodiversity database containing knowledge extracted from scientific literature, built as an Open Biodiversity Knowledge Management System.
Apart from coordinating the Horizon 2020-funded project BiCIKL, scholarly publisher and technology provider Pensoft has been the engine behind what is likely to be the first production-stage semantic system to run on top of a reasonably-sized biodiversity knowledge graph.
OpenBiodiv is a biodiversity database containing knowledge extracted from scientific literature, built as an Open Biodiversity Knowledge Management System.
As of February 2023, OpenBiodiv contains 36,308 processed articles; 69,596 taxon treatments; 1,131 institutions; 460,475 taxon names; 87,876 sequences; 247,023 bibliographic references; 341,594 author names; and 2,770,357 article sections and subsections.
In fact, OpenBiodiv is a whole ecosystem comprising tools and services that enable biodiversity data to be extracted from the text of biodiversity articles published in data-minable XML format, as in the journals published by Pensoft (e.g. ZooKeys, PhytoKeys, MycoKeys, Biodiversity Data Journal), and other taxonomic treatments – available from Plazi and Plazi’s specialised extraction workflow – into Linked Open Data.
“I believe that OpenBiodiv is a good real-life example of how the outputs and efforts of a research project may and should outlive the duration of the project itself. Something that is – of course – central to our mission at BiCIKL.”
explains Prof Lyubomir Penev, BiCIKL’s Project Coordinator and founder and CEO of Pensoft.
“The basics of what was to become the OpenBiodiv database began to come together back in 2015 within the EU-funded BIG4 PhD project of Victor Senderov, later succeeded by another PhD project by Mariya Dimitrova within IGNITE. It was during those two projects that the backend Ontology-O, the first versions of RDF converters and the basic website functionalities were created,”
he adds.
At the time OpenBiodiv became one of the nine research infrastructures within BiCIKL tasked with the provision of virtual access to open FAIR data, tools and services, it had already evolved into a RDF-based biodiversity knowledge graph, equipped with a fully automated extraction and indexing workflow and user apps.
Currently, Pensoft is working at full speed on new user apps in OpenBiodiv, as the team is continuously bringing into play invaluable feedback and recommendation from end-users and partners at BiCIKL.
As a result, OpenBiodiv is already capable of answering open-ended queries based on the available data. To do this, OpenBiodiv discovers ‘hidden’ links between data classes, i.e. taxon names, taxon treatments, specimens, sequences, persons/authors and collections/institutions.
Thus, the system generates new knowledge about taxa, scientific articles and their subsections, the examined materials and their metadata, localities and sequences, amongst others. Additionally, it is able to return information with a relevant visual representation about any one or a combination of those major data classes within a certain scope and semantic context.
Users can explore the database by either typing in any term (even if misspelt!) in the search engine available from the OpenBiodiv homepage; or integrating an Application Programming Interface (API); as well as by using SPARQL queries.
On the OpenBiodiv website, there is also a list of predefined SPARQL queries, which is continuously being expanded.
“OpenBiodiv is an ambitious project of ours, and it’s surely one close to Pensoft’s heart, given our decades-long dedication to biodiversity science and knowledge sharing. Our previous fruitful partnerships with Plazi, BIG4 and IGNITE, as well as the current exciting and inspirational network of BiCIKL are wonderful examples of how far we can go with the right collaborators,”
The frog lives in the pristine streams of the Río Negro-Sopladora National Park, a protected area with thousands of hectares of almost primary forests in Ecuador.
“In a stream in the forest there lived a Hyloscirtus. Not a nasty, dirty stream, with spoor of contamination and a muddy smell, nor yet a dry, bare, sandy stream with nothing in it to perch on or to eat: it was a Hyloscirtus-stream, and that means environmental quality.” (adapted from the opening of “The Hobbit” by J. R. R. Tolkien)
A magnificent new species of stream frog from the Andes of Ecuador was named after J. R. R. Tolkien, creator of Middle-earth and author of famous fantasy works “The Hobbit” and “The Lord of the Rings. It lives in the pristine streams of the Río Negro-Sopladora National Park, a recently declared protected area that preserves thousands of hectares of almost primary forests in southeastern Ecuador.
Stream frogs are a group of amphibians that inhabit the high Andes of Venezuela, Colombia, Ecuado, Peru, and Bolivia. Their life is closely linked to the pure rivers and streams in the mountain areas of the Andes, hence the name “stream frogs”. The adults live in the riparian vegetation, and their tadpoles develop among the rocks of the rapid waters of the rivers.
The researchers, Juan C. Sánchez-Nivicela, José M. Falcón-Reibán, and Diego F. Cisneros-Heredia, named the new frog Hyloscirtus tolkieni in honour of one of their favourite writer. JRR Tolkien, a renowned author, poet, philologist and academic, is the creator of Middle-earth and the father of fantastic works such as “The Hobbit” and “The Lord of the Rings”. The amazing colours of this new frog species reminded them of the magnificent creatures from Tolkien’s fantasy worlds.
Expeditions carried out since 2020 in the Río Negro-Sopladora National Park in Ecuador have allowed the discovery of a large number of species yet unknown to science. A protected area since 2018, this national park, located in the south of the country, is home to large forested areas that remain unstudied.
“For weeks, we explored different areas of the Río Negro-Sopladora National Park, walking from paramo grasslands at 3,100 meters elevation to forests at 1,000 m. We found a single individual of this new species of frog, which we found impressive due to its colouration and large size.”, indicated Juan Carlos Sánchez Nivicela, associate researcher at the Museum of Zoology of the Universidad San Francisco de Quito USFQ and the National Institute of Biodiversity, and co-author of the study where the frog is described.
The Río Negro Stream Frog is easily differentiated from all its frog releatives by its appearance and unique colouration. It is relatively large (65 mm long), a greyish green back with yellow spots and black specks, and a pale pink and black iris. Its throat, belly and flanks as well as the undersides of its legs are golden yellow with large black spots and dots, and its fingers and toes have black bars and spots and broad skin stripes.
“The new species of frog has amazing colours, and it would seem that it lives in a universe of fantasies, like those created by Tolkien. The truth is that the tropical Andes are magical ecosystems where some of the most wonderful species of flora, funga, and fauna in the world are present. Unfortunately, few areas are well protected from the negative impacts caused by humans. Deforestation, unsustainable agricultural expansion, mining, invasive species, and climate changes are seriously affecting Andean biodiversity”, said Diego F. Cisneros-Heredia, director of the Museum of Zoology of the Universidad San Francisco de Quito USFQ and associate researcher of the National Institute of Biodiversity, and co-author of the study.
The species is still only known from one locality and one individual, so information is insufficient to assess its conservation status and the risk of extinction. However, the authors agree that it is urgent to establish research and monitoring actions to study its life history and ecology, as well as its population size and dynamics. In addition, they suggest exploring new sites where additional populations may exist, and assessing whether their long-term conservation is affected by any threats, such as invasive species, mining, emerging diseases, or climate change.
The description of new species is an important mechanism to support global strategies for the conservation of vulnerable environments, since it reveals the great wealth of biodiversity that is linked to countless natural resources and environmental services. For example, amphibians are important pest controllers and play vital ecological roles in the stability of nature. Unfortunately, 57% of amphibian species in Ecuador are threatened by extinction.

A new species of snake was described from western Panama. First documented in 1977 by Dr. Charles Myers, a scientist studying amphibians and reptiles throughout Panama, it was only now that it got a scientific description.
The new snake has been given the name Dipsas aparatiritos. The genus Dipsas includes the snailsuckers, a unique group of snakes that feed on soft-bodied prey including snails extracted from their shells, slugs, and earthworms. The species epithet “aparatiritos” is Greek for unnoticed: a reference to the fact that the snake had remained hidden in plain sight for over forty years at a very well-studied field site.

Scientists Dr. Julie Ray, University of Nevada – Reno, Paola Sánchez-Martínez, Abel Batista, Daniel G. Mulcahy, Coleman M. Sheehy III, Eric N. Smith, R. Alexander Pyron and Alejandro Arteaga, have described the new species in a paper published in the open-access journal ZooKeys.
Dipsas aparatiritos has the characteristic bulbous head and brown-and-black patterning of many of the snakes in the genus. It looks very similar to its closest known relative, Dipsas temporalis, which is also found in Panama. It is now known that D. aparatiritos is endemic to, or known only from, the western and central parts of the country.

Panama has a rich diversity of snakes, with over 150 documented species in a country the size of Ireland or the U.S. state of South Carolina. Dr. Ray has documented over 55 species of snakes in Parque Nacional General de División Omar Torrijos Herrera where the newly described snake is best studied, and over 80 species in Coclé Province in Central Panama. She published a field guide, Snakes of Panama, in 2017.

Co-author of the species description Dr. Alex Pyron, The George Washington University, visited Parque Nacional General de División Omar Torrijos Herrera in June 2013 with Dr. Frank Burbrink, American Museum of Natural History. “That was my first trip to Central America,” he says. “We were able to see the after-effects of the amphibian declines. But I was struck by the diversity and abundance of snakes that were still present, including this species of snail-eater we have just described, the rare Geophis bellus [a small leaf litter snake known from just one specimen prior to this discovery] and an unusual Coralsnake.”
Despite being a new species, Dipsas aparatiritos is relatively common in Parque Nacional General de División Omar Torrijos Herrera and has been studied for years before it was described. Dr. Ray has published a paper about the diet of snail-eating snakes, where it was found that earthworms from bromeliads compose a large portion of the diet of Dipsas aparatiritos. She also co-authored a paper on trophic cascades following amphibian declines, where it was found that Dipsas aparatiritos actually was increasing in numbers due to a diet independent of amphibians.

Dipsas aparatiritos is already considered Near Threatened based on IUCN Red List standards. The snake is endemic to Panama and comes from a limited range in the cloud forests of mid-elevation, where at least 44% of the overall range has been deforested. In addition, as snakes are constantly persecuted by humans, almost all snake species are in danger of extinction in the near future. Efforts must be made to conserve these rare species, the researchers believe, especially as so many are just being described now.
“This work was a true collaboration of scientists from different countries each contributing their expertise to thoroughly understand this new species, morphologically and molecularly,” said Dr. Ray.
“We are in an exciting time in science. Naturalists and scientists must continue to document the natural world; there are many species out there yet to be found and described. The usage of molecular techniques is exciting and facilitates the confirmation of so many new species.”

Biologists at Eawag have identified ten species of whitefish in the lakes of the Reuss river system. Of these, seven have been described as distinct species for the first time – although in two cases this required inspection of specimens from historical collections, since eutrophication of lakes in the 20th century also led to the extinction of fish species in Central Switzerland.
These seven whitefish were described as separate species for the first time, including the “Albeli” from Lake Lucerne, which now bears the name Coregonus muelleri in memory of the whitefish expert Rudolf Müller. Image by Eawag
The “Edelfisch” (Coregonus nobilis) was, after the smaller “Albeli”, the second most commonly caught species of whitefish in Lake Lucerne until, in the second half of the 20th century, phosphate from domestic wastewater and nutrient-rich run-off from farmland led to a massive increase in algal blooms. Compared to the lakes of the Central Plateau, nutrient levels in Lake Lucerne were moderate, and eutrophication was short-lived; even so, due to algal decomposition, oxygen was depleted in the deeper layers of the lake. The “Edelfisch”, which reproduces in the late summer at a spawning depth of 80 metres or more, suffered as a result. Shortly before nutrient inputs decreased following the ban on phosphates in detergents and the expansion of wastewater treatment plants, stocks of this species collapsed and it was considered to be extinct in 1980. Only from the late 1990s were individual specimens caught once again, unequivocally identified as C. nobilis in 2000 by the whitefish specialist and Eawag researcher Rudolf Müller.

Five whitefish species in Lake Lucerne

As the “Edelfisch” is now a protected species, Lake Lucerne has not lost any of its historically recorded whitefish species. Indeed, in addition to the familiar “Edelfisch”, “Albeli” and “Bodenbalchen”, Eawag scientists have identified two new species – two large whitefish, differing from the previously known species in their habits, morphological characteristics and genetic composition. The pelagic “Schwebbalchen” (Coregonus suspensus) probably lives permanently in the open water, not only for foraging but also for reproduction – a spawning behaviour only previously observed in the “Blaufelchen” (C. wartmanni) of Lake Constance. Occupying a position intermediate to the pelagic “Schwebbalchen” (C. suspensus) and the “Bodenbalchen” (C. litoralis) is the littoral “Schwebbalchen” (C. intermundia).

Particularly affected by eutrophication in the mid-20th century were whitefish in Lake Zug, which – like other Central Plateau lakes – was exposed to higher nutrient levels, for a longer period, than waterbodies further upstream. As only the uppermost water layers of this 200-metre-deep lake maintained oxygen levels sufficient to support fish, two whitefish species spawning in the depths of the lake died out – the (Lake Zug) “Albeli” (C. zugensis) and “Albock” (C. obliterus). Indeed, the Lake Zug “Albock” would have been completely forgotten if specimens had not been found by Eawag scientists Oliver Selz and Ole Seehausen in the historical Steinmann-Eawag Collection. Its morphology and historical accounts indicate that the Lake Zug “Albock” was a deep‑water specialist – a specialisation only otherwise observed to the same degree in the (likewise extinct) Lake Constance Kilch (C. gutturosus) and the (still extant) Lake Thun Kropfer (C. profundus).
The only whitefish species still found in Lake Zug today, spawning near the shore, is the “Balchen”. Testifying to its survival is its new scientific name – Coregonus supersum (“I have survived”).
Species endemic to each lake
Also new are the scientific names of the Lake Lucerne “Bodenbalchen” (C. litoralis) and “Albeli” (C. muelleri). For the morphological and genetic studies carried out by Oliver Selz and Ole Seehausen in order to revise the taxonomy of whitefish showed that almost every lake in Central Switzerland has its own species of “Albeli” and “Bodenbalchen”.
Previously, the “Albeli” of Lakes Zug and Lucerne had been classified as members of the same species (C. zugensis), while the “Balchen” spawning near the shore of the various Central Swiss lakes were known as C. suidteri. These collective species names have now been inherited by the extinct Lake Zug “Albeli” (C. zugensis) and the Lake Sempach “Balchen” (C. suidteri).
The Lake Lucerne “Albeli” received the new name C. muelleri in honour of the fisheries biologist and whitefish specialist Dr Rudolf Müller (1944–2023).

A reflection of Switzerland
The lakes of the Reuss river system are a reflection of Switzerland as a whole. Since the last ice age, at least 35 whitefish species evolved in the pre-alpine lakes, usually two or more in each lake. Switzerland lost a third of these species during the period of lake eutrophication around the middle of the 20th century. Many of the lost species are known to researchers only thanks to historical collections, such as that created before the eutrophication period by the naturalist Paul Steinmann and currently curated by the Natural History Museum of Bern.

The enigmatic animals with beautiful shells are facing population declines and, possibly, even extinctions due to the activity of unregulated fisheries.
Guest blog post by Dr Gregory Barord, marine biology instructor at Central Campus and conservation biologist at the conservation organization Save the Nautilus
Nautiloids were once quite plentiful throughout the oceans, based upon the fossil record. Today, they are represented by just a handful of species, including the newly described Nautilus vitiensis of Fiji, Nautilus samoaensis of American Samoa, and Nautilus vanuatuensis of Vanuatu. These descriptions highlight the concept of allopatric speciation, or biogeographic isolation, where populations are geographically separated from other populations, resulting in a barrier to gene flow. Over time, these populations may eventually evolve into distinct species.

But what does it take to be able to collect the evidence needed to determine if three different populations of nautiluses are in fact three different species? For me, this is the best/worst part of the overall process, because nautilus fishing is not easy. For our team, it starts with building large, steel traps that are about a meter cubed. Then, we wrap the steel frame (ouch), with chicken wire (ouch) mesh (ouch), create an entry hole (ouch), attach it to a surface buoy with about 300 meters of fishing line, and bait it with (ouch) raw meat, usually chicken! Trap construction may take place on a nice beach or a bit inland in the rain or in a warm warehouse. Wherever it takes place, you will have some memories, I mean little scars, on your hands from working with the chicken wire. Looking down at my hands right now, I can remember where I was by looking at each of those scars… worth it!
Tossing the traps into the sea at dusk is the easy part. Load them on the boat, find the right depth, and tip them over the side of the boat. The hard part is retrieving the traps the next day, after about 12 hours of the raw chicken scent moving through the currents. There are a number of methods we’ve used to pull the traps up, from mechanical winches, hand-powered winches, float systems, boat pulls, and of course, just pulling with one hand at a time. Invariably, something happens in each location where we are just pulling the trap up from 300 meters one meter at a time, which takes a good half hour at least. But, at least you are getting a VERY good work-out. Eventually, you see the trap and these white little orbs in it and you know you’ve caught some nautiluses and the pulling is almost done, for now.

The next step might be my favorite. One of us jumps in the water and free dives about 5 meters to carefully (ouch, that chicken wire) reach for the nautiluses in the trap and bring them to the surface. You are face to face with these uniquely, misunderstood organisms who seem like this is just another day for them. For me, this is exhilarating! Once on the boat, they are placed in chilled seawater and from then on, the data collection happens fast. With the living organism in hand, you can start to glean even more of the differences between the species, examining the hood ornaments, or lack thereof. After some photos, measurements, and non-lethal tissue samples, the nautiluses are released and burped.
Nautilus vanuatuensis.
Maybe nautilus burping is my favorite part. To do this, we either dive with SCUBA or free dive with the nautiluses, and ensure there are no air bubbles trapped in the shell that may cause them to be positively buoyant. Imagine, you have one nautilus in each hand and you start swimming down, your feet and the nautilus tentacles pointed toward the surface. At a sufficient depth, you release them and observe their buoyancy. As the nautiluses compose themselves and jet back down to their nektobenthic habitat 300 meters below, you realize you may never see that individual nautilus again, and that nautilus may never see another human, well, maybe they will…
For me, the impetus for this publication in ZooKeysis rooted in nautilus conservation efforts. Over the last 20 years, I have studied nautiluses from many angles and for over 10 years now, have worked with an international team of folks to address nautilus conservation issues. For many nautiluses, probably millions, they were caught in much the same way that our team collected nautiluses. However, their first meeting with humans was their last as they were pulled from the trap, ripped from their protective shell, and tossed back in the ocean, used as bait, or, rarely, consumed. The shell is the attractive piece for shell traders and the living body has no value. It is like shark finning in that sense. As a direct result of these unregulated fisheries, populations of nautiluses have crashed, some have reportedly gone extinct, and international and country level legislation and regulations has been enacted.

Nautilus vitiensis.
Currently, there are no known fisheries in Fiji, American Samoa, or Vanuatu so the risk of these populations decreasing from fisheries is low, at the moment. Now, what is the risk to these same populations from ocean acidification, increased sedimentation, eutrophication, warming seas, and over-fishing of other species connected to the ecosystem nautiluses reside in? Right now, we simply do not know. Our conservation efforts started with simply counting how many nautiluses were left in different areas across the Indo-Pacific, then recording them in their natural habitat, then tracking their migrations, and now describing new species. There are still many questions to address regarding where they lay eggs, what they eat, and how they behave.
All nautiluses have long been grouped together when describing their natural history, but as we continue to uncover the nautilus story, it is increasingly obvious that each population of nautiluses is different, as exemplified by these three new species descriptions. This is certainly an exciting time for nautilus research, as we uncover more and more information about the secret life of nautiluses. I just hope that this is also an exciting time for nautiluses as well, and they continue doing their nautilus thing as they have done for millions of years.
Five new drop-dead-gorgeous tree-dwelling snake species were discovered in the jungles of Ecuador, Colombia, and Panama. Conservationists Leonardo DiCaprio, Brian Sheth, Re:wild, and Nature and Culture International chose the names for three of them in honor of loved ones while raising awareness about the issue of rainforest destruction at the hands of open-pit mining operations. The research was conducted by Ecuadorian biologist Alejandro Arteaga, an Explorers Club Discovery Expedition Grantee, and Panamanian biologist Abel Batista.
The mountainous areas of the upper-Amazon rainforest and the Chocó-Darién jungles are world-renowned for the wealth of new species continually discovered in this region. However, it is becoming increasingly clear that they also house some of the largest gold and copper deposits in the world. During the COVID-19 pandemic, the proliferation of illegal open-pit gold and copper mining operations in the jungles of Ecuador, Colombia, and Panama reached a critical level and is decimating tree-dwelling snake populations.

Neotropical snail-eating snakes (genera Sibon and Dipsas) have a unique lifestyle that makes them particularly prone to the effects of gold and copper mining. First, they are arboreal, so they cannot survive in areas devoid of vegetation, such as in open-pit mines. Second, they feed exclusively on slugs and snails, a soft-bodied type of prey that occurs mostly along streams and rivers and is presumably declining because of the pollution of water bodies.
“When I first explored the rainforests of Nangaritza River in 2014, I remember thinking the place was an undiscovered and unspoiled paradise,” says Alejandro Arteaga, author of the research study on these snakes, which was published in the journal ZooKeys. “In fact, the place is called Nuevo Paraíso in Spanish, but it is a paradise no more. Hundreds of illegal gold miners using backhoe loaders have now taken possession of the river margins, which are now destroyed and turned into rubble.”

The presence of a conservation area may not be enough to keep the snail-eating snakes safe. In southeastern Ecuador, illegal miners are closing in on Maycu Reserve, ignoring landowner rights and even making violent threats to anyone opposed to the extraction of gold. Even rangers and their families are tempted to quit their jobs to work in illegal mining, as it is much more lucrative. A local park ranger reports that by extracting gold from the Nangaritza River, local people can earn what would otherwise be a year’s salary in just a few weeks. “Sure, it is illegal and out of control, but the authorities are too afraid to intervene,” says the park ranger. “Miners are just too violent and unpredictable.”

In Panama, large-scale copper mining is affecting the habitat of two of the new species: Sibon irmelindicaprioae and S. canopy. Unlike the illegal gold miners in Ecuador and Colombia, the extraction in this case is legal and at the hands of a single corporation: Minera Panamá S.A., a subsidiary of the Canadian-based mining and metals company First Quantum Minerals Ltd. Although the forest destruction at the Panamanian mines is larger in extent and can easily be seen from space, its borders are clearly defined and the company is under the purview of local environmental authorities.

“Both legal and illegal open-pit mines are uninhabitable for the snail-eating snakes,” says Arteaga, “but the legal mines may be the lesser of two evils. At the very least they respect the limit of nearby protected areas, answer to a higher authority, and are presumably unlikely to enact violence on park rangers, researchers, and conservationists.”

Sibon canopy, one of the newly described species, appears to have fairly stable populations inside protected areas of Panama, although elsewhere nearly 40% of its habitat has been destroyed. At Parque Nacional Omar Torrijos, where it is found, there has been a reduction in the number of park rangers (already very few for such a large protected area). This makes it easier for loggers and poachers to reach previously unspoiled habitats that are essential for the survival of the snakes.

Lack of employment and the high price of gold aggravate the situation. No legal activity can compete against the “gold bonanza.” More and more often, farmers, park rangers, and indigenous people are turning to illegal activities to provide for their families, particularly during crisis situations like the COVID-19 pandemic, when NGO funding was at its lowest.

“These new species of snake are just the tip of the iceberg in terms of new species discoveries in this region, but if illegal mining continues at this rate, there may not be an opportunity to make any future discoveries,” concludes Alejandro Arteaga.

Fortunately, three NGOs in Ecuador and Panama (Khamai, Nature and Culture International, and Adopta Bosque) have already made it their mission to save the snake’s habitat from the emerging gold mining frenzy. Supporting these organizations is vital, because their quest for immediate land protection is the only way to save the snakes from extinction.

Nestled amongst a chain of islands in the southern reaches of Southeast Asia, Timor-Leste occupies the eastern half of the island of Timor, the largest of the Lesser Sunda Islands that also include Bali and Komodo, the latter of which is home to the Komodo Dragon. In May 2002, Timor-Leste (officially the Democratic Republic of Timor-Leste) became the first sovereign nation in the 21st century and is currently the 4th youngest country in the world.

Even though the country lies in the highly biodiverse region of Wallacea, its biodiversity is relatively poorly known, partly because decades of pre-independence violence and conflict have hindered biological surveys. In August 2022, a partnership between the Lee Kong Chian Natural History Museum (Singapore), Conservation International, and the Ministry of Agriculture and Fisheries of Timor-Leste conducted preliminary biological surveys across the eastern part of the island. The surveys specifically targeted remote and underexplored areas, such as the isolated mountain of Mundo Perdido (“Lost World” in Portuguese) and Nino Konis Santana National Park (NKS)—the first and largest national park in Timor-Leste.

NKS is an enormous park that covers 1,236 square kilometers of land and is mainly characterized by lowland tropical forests. In it, there are several limestone caves of archaeological importance, and it was in one of those caves that a new gecko species was found.
While surveying the Lene Hara cave during the day, a member of the research team caught a glimpse of a lizard scurrying on the ground before disappearing into a crevice. Dr. Chan Kin Onn, a herpetologist at the Lee Kong Chian Natural History Museum and the lead author of a study published in ZooKeys, sprung into action. Soon, he found himself wedged into a tight crevice in hopes of capturing the lizard.

“I couldn’t get to the lizard because the crack was too narrow, but I saw the rear half of its body and could tell that it was a bent-toed gecko from the genus Cyrtodactylus. New species of bent-toed geckos are being discovered all across Southeast Asia and due to the remoteness of the cave, the potential for this gecko to be a new species was high,” explained Dr. Chan.
Several hours later, under the cover of darkness, the team was back in the cave, this time equipped with flashlights. “Bent-toed geckos are usually nocturnal and can be skittish during the day. Our best chance at capturing them would be at night,” says Dr. Chan.True enough, after just one hour of looking, they collected ten specimens. A few weeks later, the gecko from Lena Hara cave was confirmed to be a new species based on DNA analysis and external morphological characteristics.

The new species is named Cyrtodactylussantana, in reference to Nino Konis Santana National Park. The park’s name honors Nino Konis Santana, a freedom fighter who led the Falintil militia against the Indonesian occupation of Timor-Leste.
Even though past surveys have documented several populations of bent-toed geckos in Timor-Leste, none of them had been identified to the species level and thus, remain unnamed. Cyrtodactylussantana is the first bent-toed gecko in Timor-Leste formally described as a species.
The expedition also discovered several interesting plants and crabs that are currently being examined, all of which have the potential to be new species. “We have barely scratched the surface of Timor-Leste’s biodiversity. New discoveries can have profound impacts, because Timor-Leste is a substantial landmass bounded by deep sea trenches and is located at the fringe of the Wallacean Biodiversity Hotspot and Weber’s Line, a transitional zone between Oriental and Australasian fauna” remarked the researchers. Understanding the biodiversity of Timor-Leste could provide key insights into the divergence, evolution, and distribution of species, they believe.

Another year rolled by and we at Pensoft have a lot to celebrate! This year, we marked our 30th birthday, and what a ride it’s been! We thank all of you for sticking around and helping us put biodiversity science in the spotlight where it deserves to be.
The holiday season is always great fun, but for us, every biodiversity or conservation win is reason enough to celebrate. And we’ve had so many this year! We already showed you our top species for the first half of 2022. Here’s an update for the second half with the most exciting new species that we’ve published across our journals:
The elusive owl from a remote island
The Principe scops-owl (Otus bikegila) was discovered on the small island of Príncipe, just off Africa’s western coast. Its existence had been suspected since 1998, but locals said its presence on the island could be traced back to 1928.
The bird is endemic to the island of Príncipe. Furthermore, the research team behind its discovery noted that it can be found only in the remaining old-growth native forest on the island, in an area that largely remains uninhabited.
8/9 The discovery and the subsequent scientific description were the result of a long process requiring the contribution of many people. It was a privilege to be a part of this. Thanks in particular to An Bollen, Barbara, Bikegila and Martim for all the help & the hard work. pic.twitter.com/ufdDlIdFXz
Otus is the generic name given to a group of small owls sharing a common history, commonly called scops-owls. They are found across Eurasia and Africa, and include such widespread species as the Eurasian scops-owl (Otus scops) and the African scops-owl (Otus senegalensis).
The species epithet “bikegila”, in turn, was chosen in homage of Ceciliano do Bom Jesus, nicknamed Bikegila – a former parrot harvester from Príncipe Island and now a park ranger on the island.The new species quickly became insanely popular, generating memes (a true sign of its popularity!). One website even described it as “a flying meme-generator that sounds like a newborn puppy.”
Nepenthes pudicais a carnivorous plant that grows prey-trapping contraptions underground, feeding off subterranean creatures such as worms, larvae and beetles.
It belongs to pitcher plants – a group of carnivorous plants with modified leaves (called pitfall traps or pitchers) that help them catch their prey.
Pitcher plants usually produce pitfall traps above ground at the surface of the soil or on trees. N. pudica is the first pitcher plant known to catch its prey underground.
At first, the researchers thought the deformed pitcher protruding from the soil that they saw had accidentally been buried. Only later, when they found additional pitcherless plants, did they consider the possibility that the pitchers might be buried in the soil.
Then, as one of the researchers was taking photos, he tore some moss off the base of a tree and found a handful of pitchers.
The unique plant, however, could already be under threat. As it only lives in one small area of Indonesia, scientists believe it should be classed as Critically Endangered.
In November 2021, biologist Alejandro Arteaga and his colleagues were traveling through the cloud forests of Ecuador looking for toads, when a local woman told them she had seen odd snakes slithering around a graveyard. Based on her description, the team suspected they might be ground snakes from the genus Atractus, which had never been scientifically recorded in that area of Ecuador.
Indeed, they were able to discover three new snake species living beneath graves and churches in remote towns in the Andes mountains.
The “small, cylindrical, and rather archaic-looking” snakes all belong to a group called ground snakes. In general, not a lot of people are familiar with ground snakes, as they usually remain hidden underground.
Sometimes life gives you lemons, and sometimes you go looking for frogs and end up finding three new species of snake! In this episode we hear from Alejandro Arteaga about his new species from the Ecuadorian Andes.https://t.co/1YjQXSNJcJpic.twitter.com/8IKJGc2sCI
All three snakes were named in honor of institutions or people supporting the exploration and conservation of remote cloud forests in the tropics. Atractus zgap, pictured here, was named in honor of theZoological Society for the Conservation of Species and Populations (ZGAP), a program seeking to conserve unknown but highly endangered species and their natural habitats throughout the world.
However, the majority of the native habitat of these new snakes has already been destroyed. As a result of the retreating forest line, the ground snakes find themselves in the need to take refuge in spaces used by humans (both dead and alive), where they usually end up being killed on sight.
Unlike some other participants in this list, this one took a while before it was confirmed as a new species: “We did not discover that it was a new species overnight,” says Oscar Lasso-Alcalá, one of the people behind its discovery.
A. mikoljii is a new species for science, but it is not a “new species” for people who already knew it locally under the name of Pavona, Vieja, or Cupaneca in Venezuela or Pavo Real, Carabazú, Mojarra and Mojarra Negra in Colombia. Nor for the aquarium trade, where it is highly appreciated and has been known by the common name of Oscar.
Moreover, the species has been of great food importance for thousands of years for at least nine indigenous ethnic groups, and for more than 500 years to the hundreds of human communities of locals who inhabit the Orinoco River basin in Venezuela and Colombia. In the plains of Orinoco, it is considered a delicacy “due to its pleasant taste and enhanced texture”.
Oscar Lasso-Alcalá has a special relationship with this fish. “It is more than just a fish in an aquarium since it is considered a true pet,” he says.
Recently, Javier Lobon-Rovira, one of the people behind the discovery of this new gecko, told us what it was like to find this exciting new species: “That night we were tired, so we decided to have a short walk around the camp. And… there it was…! Like a ghost, this small, cryptic, and elusive gecko started showing up in every big rock boulder.”
Kolekanos spinicaudusis part of Kolekanos, a unique and iconic gecko genus that is only known from southwestern Angola.
Until this discovery, Kolekanos only had one species in the genus, known only from ~200km south of the new discovery, but that species had feathers on its tail, not spines like K. spinicaudus. Immediately, the researchers knew they were dealing with a Kolekanos… but they were astonished to see the spines.
GECKO SUNDAY! Another #NewSpecies of #gecko for 2022! Meet: Kolekanos spinicaudus • A new Feather-tailed Leaf-toed Gecko, Kolekanos (Squamata: Gekkonidae) from the poorly explored Savannah of western Angola 2022. link/summary: https://t.co/TWhm0JGhcypic.twitter.com/Z8wcug7IIt
The scientific name “spinicaudus” refers to the unique appearance of the tail of this new species.
K. spinicaudus’s home in southern Angola remains poorly explored, even as it has been considered as an important source of diversification and endemism in West Africa.
“Insects in general are so diverse and so important, yet we don’t have scientific descriptions or names for so many of them,” says Dr Kit Prendergast, from the Curtin School of Molecular and Life Sciences.
The new bee species she discovered, Leioproctus zephyris excellent proof that we still have a lot to learn about bee biodiversity.
The story behind L. zephyr’s name is quite interesting – it was named after Zephyr the Maremma dog, Dr Prendergast’s fellow companion. The researcher says Zephyr played an important role in providing emotional support during her PhD. The name also references the dog-like “snout” in the bee’s anatomy that she found rather unusual.

The bee species was in fact first collected in 1979, but it had to wait until 2022 to be officially described.
However, Dr Prendergast says its future remains uncertain, as it is highly specialised, and has a very restricted, fragmented distribution.
“The Leioproctus zephyr has a highly restricted distribution, only occurring in seven locations across the southwest WA to date, and have not been collected from their original location. They were entirely absent from residential gardens and only present at five urban bushland remnants that I surveyed, where they foraged on two plant species of Jacksonia.”
Honorable mention: Two scorpion species described by high-school citizen scientists
In 2019, California teenagers Harper Forbes and Prakrit Jain were looking at entries on the naturalist social network iNaturalist, when they noticed a mysterious scorpion that a citizen scientist had encountered near a lake in theMojave Desert. The species had remained unidentified since it was uploaded six years earlier.
The entry that they were looking at was a yet undescribed scorpion species whose name they would add to the fauna of California. Shortly after, they found another entry on iNaturalist that also appeared to be an unknown scorpion species.
The new species, Paruroctonus soda and Paruroctonus conclusus, are playa scorpions, meaning they can only be found around dry lake beds, or playas, from the deserts of Central and Southern California.
This is SUCH impressive work on 2 new-to-science #Scorpion species from California, published by high school students Prakrit Jain & Harper Forbes in collaboration with @ArachnologyNerd! #Arachnology 🦂
“These kids can find anything,” Dr Esposito told The Guardian. “You set them out in a landscape and they’re like: ‘Here’s every species of snake, here’s every scorpion, every butterfly,’ and it’s kind of incredible.”
Forbes and Jain were still in high school when they made their groundbreaking discoveries. Now they are in college: Forbes at the University of Arizona studying evolutionary biology and Jain at the University of California, Berkeley, for integrative biology.
All journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
In support of transparency and openness in scholarly publishing and academia, the scientific publisher and technology provider Pensoft joined the Journal Comparison Service (JCS) initiative by cOAlition S, an alliance of national funders and charitable bodies working to increase the volume of free-to-read research.
As a result, all journals published by Pensoft – each using the publisher’s self-developed ARPHA Platform – provide extensive and transparent information about their costs and services in line with the Plan S principles.
The JCS was launched to aid libraries and library consortia – the ones negotiating and participating in Open Access agreements with publishers – by providing them with everything they need to know in order to determine whether the prices charged by a certain journal are fair and corresponding to the quality of the service.
According to cOAlition S, an increasing number of libraries and library consortia from Europe, Africa, North America, and Australia have registered with the JCS over the past year since the launch of the portal in September 2021.
While access to the JCS is only open to librarians, individual researchers may also make use of the data provided by the participating publishers and their journals.
This is possible through an integration with the Journal Checker Tool, where researchers can simply enter the name of the journal of interest, their funder and affiliation (if applicable) to check whether the scholarly outlet complies with the Open Access policy of the author’s funder. A full list of all academic titles that provide data to the JCS is also publicly available. By being on the list means a journal and its publisher do not only support cOAlition S, but they also demonstrate that they stand for openness and transparency in scholarly publishing.
“We are delighted that Pensoft, along with a number of other publishers, have shared their price and service data through the Journal Comparison Service. Not only are such publishers demonstrating their commitment to open business models and cultures but are also helping to build understanding and trust within the research community.”
said Robert Kiley, Head of Strategy at cOAlition S.
