A new species of caddisfly, Tinodes lumbardhi, was found in a sidestream of the Lumbardhi i Deçanit River in Kosovo’s Bjeshkët e Nemuna National Park. The discovery, made by Professor Halil Ibrahimi of the University of Prishtina and his research team, underscores the region’s high biodiversity and urgent need for conservation.

The aquatic insect is small, with its wings less than 5 mm long. Its name, “lumbardhi,” honors the local Albanian name for the river, meaning “the white river.”
“The discovery of Tinodes lumbardhi is both a celebration of Kosovo’s unique natural heritage and a wake-up call for conservation,” said Professor Halil Ibrahimi. “The survival of these species depends on our ability to protect their fragile habitats.”

Hosting several rare and endemic species, Bjeshkët e Nemuna, a mountainous region in western Kosovo, is a hotspot for caddisfly diversity. Despite this richness, however, Kosovo’s freshwater ecosystems face escalating threats from human activities. Hydropower development, pollution, and water extraction have severely degraded habitats like the Lumbardhi i Deçanit River, leading in some areas to impoverished insect communities and an alarming absence of fish. Sidestreams like the one where T. lumbardhi was found serve as critical refuges for rare species but remain vulnerable to environmental pressures.
Caddisflies, known for their sensitivity to environmental changes, are key bioindicators of freshwater ecosystem health. These small insects are not only vital for biodiversity but also for maintaining ecological stability in the face of threats such as climate change and habitat destruction.
Heavy environmental pressures endanger the aquatic fauna of Lumbardhi i Deçanit River in Kosovo.
Kosovo’s caddisfly fauna has seen significant advancements in recent years, with contributions from Ibrahimi and his team shedding light on the region’s ecological treasures. Their work has revealed species such as Potamophylax kosovaensis and Potamophylax coronavirus, emphasizing the importance of ongoing research and conservation efforts.
The discovery of Tinodes lumbardhi adds to the growing recognition of Bjeshkët e Nemuna as a biodiversity hotspot of international significance. In their research paper, published in Biodiversity Data Journal, the researchers call for urgent targeted conservation measures to mitigate the impacts of hydropower development and other anthropogenic threats in the region. “Protecting these rare species and their habitats is not only a moral imperative but also a crucial step toward sustaining the ecological integrity of Kosovo’s freshwater systems,” says Halil Ibrahimi in conclusion.

The 2010 Gulf of Mexico Deepwater Horizon was the largest accidental oil spill in history. With almost 100 million gallons (379 million liters) of oil combined with dispersants suggested to remain in the Gulf, it is one of the worst pollution events ever. More than a decade later, its long-term effects are still not fully understood.

In a new study, researchers from Louisiana State University and Tulane University examined the endemic Gulf of Mexico fish species that may have been most impacted by the oil spill to see how their distribution has changed over the years. To get their data, they studied museum specimens from natural history collections, looked at relevant literature, and combed biodiversity databases.

With 1541 fish species known from the region, and 78 endemic fish species, the Gulf of Mexico is one of the most biologically rich and resilient marine environments in the world, but how much of this diversity is still left intact?
The study found that 29 out of the Gulf’s 78 endemic fish species haven’t been reported in museum collections since 2010. The Yucatan killifish, for example, which is considered endangered, was last reported pre-spill, in 2005, off the Yucatán Peninsula.
Six of the non-reported species are considered of greatest concern, because their areas of distribution largely overlap with the affected area – although the authors note that their absence in the Gulf in recent years cannot automatically be attributed to the oil spill.

“Understanding the impacts of catastrophic environmental events such as the 2010 Gulf of Mexico Oil Spill does not end when the wellhead is capped or when the last drops of oil cease to flow. The disaster only begins to end when the data no longer show impacts of the event. We are far from the beginning of the end for the Deepwater Horizon Oil Spill. Lingering chemicals, lost generations of wildlife and a continued ecosystem imbalance may all be factors that prevent an environment from rebounding from such cataclysmic events,” the authors note in their research article.
However, they also point out that nature’s ability to recover should not be overlooked.
“The Gulf of Mexico continues to face many challenges, from the Dead Zone, to climate change, loss of coast habitats and continued oil spills. Efforts like this report aim to bring attention to vulnerable species that continue to be impacted by human activities and to the unique endemic fauna of the region,” the researchers write in conclusion.

A group of scientists led by researchers of Khamai Foundation discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador. This groundbreaking discovery was made official in a study published in the open-access journal Evolutionary Systematics.
Prior to this research, the captivating new vipers, now recognized as among the most alluring ever found, were mistakenly classified as part of a single, highly variable species spanning from Mexico to northwestern Peru. The decade-long study initiated with an unexpected incident wherein one of the authors was bitten by one of these previously undiscovered species.
Distribution of the palm pitvipers of the Bothriechis schlegelii species complex, including the five new species described in Arteaga et al. 2014.
Eyelash vipers stand out due to a distinctive feature: a set of enlarged spine-like scales positioned atop their eyes. These “lashes” bestow upon the snakes a formidable and fierce appearance, yet the true purpose of this feature remains unknown. What is definite, however, is that certain populations exhibit longer, and more stylized eyelashes compared to others. The variations in the condition of the eyelashes led researchers to hypothesize the existence of undiscovered species.
The clue that led the researchers to suspect that there were new species of eyelash vipers was the fact that some populations in the cloud forests of Ecuador had almost no “lashes.” Photos by Lucas Bustamante and Jose Vieira.
Eyelash vipers are also famous for another feature: they are polychromatic. The same patch of rainforest may contain individuals of the turquoise morph, the moss morph, or the gold morph, all belonging to the same species despite having an entirely different attire. “No two individuals have the same coloration, even those belonging to the same litter (yes, they give birth to live young),” says Alejandro Arteaga, who led the study.
For some of the species, there is a “Christmas” morph, a ghost morph, and even a purple morph, with the different varieties sometimes coexisting and breeding with one another. The reason behind these incredible color variations is still unknown, but probably enables the vipers to occupy a wide range of ambush perches, from mossy branches to bright yellow heliconias.

Where do these new snakes live?
Three of the five new species are endemic to the eastern Cordillera of Colombia, where they occupy cloud forests and coffee plantations. One, the Rahim’s Eyelash-Pitviper, stands out for occurring in the remote and pristine Chocó rainforest at the border between Colombia and Ecuador, an area considered “complex to visit” due to the presence of drug cartels. The Hussain’s Eyelash-Pitviper occurs in the forests of southwestern Ecuador and extreme northwestern Peru. The researchers outline the importance of conservation and research in the Andes mountain range and its valleys due to its biogeographic importance and undiscovered megadiversity.

What’s with the venom?
“The venom of some (perhaps all?) of the new species of vipers is considerably less lethal and hemorrhagic than that of the typical Central American Eyelash-Viper,” says Lucas Bustamante, a co-author of the study. Lucas was bitten in the finger by the Rahim’s Eyelash-Pitviper while taking its pictures during a research expedition in 2013. “I experienced intermittent local pain, dizziness and swelling, but recovered shortly after receiving three doses of antivenom in less than two hours after the bite, with no scar left behind,” says Bustamante.
Researcher Alejandro Arteaga examines the fangs of Central American Eyelash-Pitviper (Bothriechis nigroadspersus) in the Darién jungle of Panamá.
How threatened are these new species?
One of the study’s key conclusions is that four of the species in the group are facing a high risk of extinction. They have an extremely limited geographic range and 50% to 80% of their habitat has already been destroyed. Therefore, a rapid-response action to save the remaining habitat is urgently needed.

Who is honored with this discovery?
Two of the new species of vipers, the Rahim’s Eyelash-Pitviper (Bothriechis rahimi) and the Hussain’s Eyelash-Pitviper (B. hussaini), are named in honor of Prince Hussain Aga Khan and Prince Rahim Aga Khan, respectively, in recognition of their support to protect endangered global biodiversity worldwide through Focused On Nature (FON) and the Aga Khan Development Network. The Shah’s Eyelash-Pitviper (B. rasikusumorum) honors the Shah family, whereas the Klebba’s Eyelash-Pitviper (B. klebbai) and the Khwarg’s Eyelash-Pitviper (B. khwargi) honor Casey Klebba and Dr. Juewon Khwarg, respectively, for supporting the discovery and conservation of new species.

What is next?
Khamai Foundation is setting up a reserve to protect a sixth new species that remained undescribed in the present study. “The need to protect eyelash vipers is critical, since unlike other snakes, they cannot survive without adequate canopy cover. Their beauty, though worthy of celebration, should also be protected and monitored carefully, as poachers are notorious for targeting charismatic arboreal vipers for the illegal pet trade of exotic wildlife,” warns Arteaga. Finally, he and his team encourage the support of research on the venom components of the new species of vipers. This will promote their conservation as well as help communities that regularly encounter eyelash pitvipers.

One of the most beautiful vanilla orchid species in the Neotropical region grows in one of the most hostile environments in the Brazilian Cerrado, the Brazilian Campos Rupestres of the Espinhaço Range. “The Espinhaço refuges evolved between the Atlantic Forest and Amazonia Biomes as a consequence of extreme environmental conditions and climatic fluctuations during the Tertiary and Quaternary periods,” explains Emerson Ricardo Pansarin, one of the researchers behind the discovery of a new vanilla orchid.
Vanilla rupicola.
Brazilian Campos Rupestres have many endemic species, and a new study published in the journal PhytoKeys has just added one more.
What makes Vanilla rupicola remarkable is the fact that it grows on rock outcrops. “In this locality, Vanilla rupicola shows a reptant habit on rock outcrops and rooting in rock clefts. The elevation is from 800 to 1300 m a.s.l.,” the researchers write in their paper. Its flowers produce a sweet fragrance that can be noticed during the hottest hours of the day.

“For years we traveled through the mountains of the Espinhaço Range until we found the flowering population,” says Emerson Ricardo Pansarin.
Vanilla rupicola.
“Vanilla rupicola emerges in an essentially Amazonian clade. It seems plausible that the ancestor of this new taxon derived from an Amazonian taxon adapted to the environmental conditions of the Espinhaço Range and evolved in this particular environment,” he adds.
Vanilla rupicola is a rare species currently known to grow in a mountain-chain of Diamantina, in the ERMG Espinhaço Range, and the researchers tentatively classify it as Endangered.

“Dormice of Europe (Gliridae)” – an illustration combining watercolour and pencil – and Denitsa Peneva won at the Illustraciencia competition in the “Nature Illustration” category.
“Dormice of Europe (Gliridae)” – an illustration combining watercolour and pencil – and its author Denitsa Peneva won at the Illustracienciacompetition in the “Nature Illustration” category. This year, the contest saw over 500 works.
Denitsa’s illustration depicts five dormouse species known from Europe: the Roach’s mouse-tailed or ground dormouse (Myomimus roachi), the forest dormouse (Dryomys nitedula), the European edible dormouse (Glis glis), the hazel dormouse (Muscardinus avellanarius) and the garden dormouse (Eliomys quercinus). Each of the rodents is seen on a plant that is typical either for its habitat or diet. Respectively, one of the species – which is a carnivore – is shown next to a snail.
Curiously, “Dormice of Europe (Gliridae)” was inspired by last year’s 11th International Dormouse Conference, which took place in Svilengrad, Bulgaria. The locality was not chosen at random. It had just recently been found to house a large population of the rarest dormouse species for Europe. At the time, the Roach’s mouse-tailed or ground dormouse (Myomimus roachi), a species endemic to the Balkans, had not been encountered for almost 40 years.

The two new species of butterworts were discovered in poorly explored, remote areas in the Amotape-Huancabamba zone, a biodiversity hotspot in southern Ecuador.
A team of botanists from Ecuador, Germany, and the United States has described two new species of carnivorous plants with striking appearance. They are part of the butterworts (genus Pinguicula), a group of flowering plants with about 115 species that can catch and digest small insects with their sticky leaves. Whereas the majority of butterwort species is distributed in the northern hemisphere, these new species were discovered in the high Andes of southern Ecuador, close to the border with Peru.

Carnivorous plants use animals (usually small insects) as an additional source of nutrients to compensate the nutrient deficiency of the substrate they’re growing in. This gives them a competitive advantage over other plants and enables them to thrive in challenging habitats. The tropical high Andes have a variety of such habitats, for example marshland and rocky slopes covered in constant rain and clouds.
The two new species described in the study, Pinguicula jimburensis and Pinguicula ombrophila, were found on the shore of a highland lagoon at 3400 m and on a nearly vertical rock face at 2900 m, respectively. Their small-scale habitats lie within the so-called Amotape-Huancabamba zone, which encompasses large portions of southern Ecuador and northern Peru. This area is characterized by exceptional biodiversity, due in part to the fact that the rugged terrain and varied climate of the Andes provide so many microhabitats.
Pinguicula jimburensissp. nov. Photograph by Kabir Montesinos.
“And as small and scattered as the species’ suitable habitats are, so is the species composition,”
“Both of these new species are only known from a single location, where only a few dozens of plant individuals occur in each case.”
For one of them, only one population with about 15 mature individuals was discovered, making it vulnerable even if it is hidden in an isolated, difficult-to-access area. This narrow endemism (limited distribution in a particular area) is typical of the Amotape-Huancabamba zone, and there are many more new plant and animal species awaiting discovery, Henning says.
With the description of these two new species, the number of Pinguicula species recorded in Ecuador has tripled, as previously only P. calyptrata was known, discovered by none other than Alexander von Humboldt. The authors are convinced that there are many more new species awaiting formal scientific recognition, but admit that lately it has been a race against time.
“The results presented in this study show that the assessment of the Neotropical biodiversity is far from complete. Even in well-known groups such as the carnivorous plants, new taxa are continuously discovered and described, in particular from remote areas that become accessible in the course of the unlimited urban sprawl,” Henning, Pérez, and their colleagues write in a scientific article dedicated to the new plants that was published in the peer-reviewed journal PhytoKeys. “This is both encouraging and worrying at the same time“.
“Relentless urban sprawl and the accompanying destruction of habitats pose a massive threat to biodiversity in general, and to the tightly-knit and specialized organisms that depend on their fragile microhabitats in particular,”
Henning points out.
Although the two new species are relatively safe from direct human interference – as they both occur within protected areas – human-induced climate change is increasingly affecting ecosystems regardless of location, especially those that rely on regular precipitation, such as mountain wetlands.
The dependence on a constant climate is even reflected in the name of one of the two new species: Pinguicula ombrophila means “rain-loving butterwort”, as the plant prefers very wet conditions, receiving moisture from the waterlogged paramo-soil and enjoying the frequent rain and fog typical for this area.

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.
An unusual looking species of bee has been discovered in bushland in Perth, Western Australia, with a wide dog-like snout.https://t.co/7UOBOrwgg7
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.
As was highlighted in the foreword to the renowned WWF Greater Mekong Report 2021, written by Prof. Dr. Thomas Ziegler, Curator for Herpetology, Ichthyology, and Invertebrates, at Cologne Zoo (Köln, Germany), there is an urgent need for more studies that identify the gaps in species conservation.
In a new scientific article, published in the open-access peer-reviewed journal Nature Conservation, Ziegler and his team present precisely such an analysis, focusing on the world’s most threatened vertebrate class: the amphibians. The share of amphibian taxa classified as threatened with extinction – 41% – is a clear indicator for the decline in global biodiversity and a warning sign for significant environmental degradation.

The scientists examined the threat status of the Vietnamese amphibians, building on the bachelor thesis of Marie Krzikowski of the University of Cologne, Germany.
One of the amphibian breeding facilities at the Cologne Zoo’s Terrarium section with offspring (larvae, eggs, terrestrial subadults) of the threatened Vietnamese Crocodile Newt (Tylototriton vietnamensis), which is successfully bred at the Zoo.
They identified 275 amphibian species known from Vietnam, noting that the number is likely to go up. The country is classified as a biodiversity hotspot, and the rate of discovering new amphibian species remains relatively high. Of these 275 species, 95 (35%) species are endemic to the country, with more than half of them reported exclusively from a single locality, which makes them especially vulnerable to extinction. Vietnam’s Central Highlands were revealed as the region with the highest species diversity (130 species), the most regionally endemic species (26 of total 67 regionally endemic species), and the most species classified as threatened by the IUCN Red List (11 species), which highlights it as a site of particular amphibian conservation concern.

In terms of threat status, 50 of the 275 species recorded so far from Vietnam (18%) are classified by the International Union for Conservation of Nature (IUCN) as threatened with extinction. These include 27 endemic species. Most of them are frogs, followed by salamanders, where 60% of the listed species are classified as threatened with extinction.
Alarmingly, 13 endemic species, including two threatened species, have been recorded exclusively from unprotected areas. For two-thirds of Vietnam’s endemic amphibians, there is no conservation data available, as their IUCN Red List status is either missing or outdated.

According to data from the Zoological Information Management System, 29 (11%) of the total 275 species reported to occur in Vietnam are represented in global zoos, including five threatened species, with the highest diversity concentrated in zoos in Europe and North America.
These facts, now compiled in the overview paper by Marie Krzikowski, Truong Q. Nguyen, Cuong T. Pham, Dennis Rödder, Anna Rauhaus, Minh D. Le and Thomas Ziegler, reveal for the first time some obvious gaps in conservation. Importantly, they will provide a directory to authorities, conservationists, rescue centers, and zoos, so that they can follow up with appropriate actions.

In particular, the conservation of microendemic species can only be addressed by organizations, NGOs or partner institutes on site, for example in the form of field work, regulatory support or protected area establishment.
Where species are at risk of disappearing rapidly, for example, species with a very limited distribution range, the establishment of ex-situ programs by local partners in cooperation with international zoos could help, in addition to in-situ conservation measures as part of the IUCN’s One Plan Approach, which combines in-situ and ex-situ efforts and various expertises for the optimum protection of a species.

The Murree Hills Frog and Hazara Torrent Frog show minimum movement out of their habitat, which makes them more unique from an ecology and conservation perspective
Amongst tetrapods, amphibians entail the highest number of threatened and data deficient species, which has put them in the limelight of research in animal ecology and conservation. Endemic species have evolved and adapted to a particular set of environmental conditions. Hence, these are more vulnerable to environmental changes and are susceptible to population declines because of their restricted distribution ranges.
The Murree Hills Frog and Hazara Torrent Frog are endemic to Pakistan and South Asian countries. They are associated with the torrential streams and nearby clear water pools situated at high elevation. These frogs are susceptible to threats like habitat degradation, urbanization, and climate change. A recent study published in the-open access journal Biodiversity Data Journal reports that these endemic frogs do not show much movement within and outside their habitat.
“We have, for the first time, used radio-transmitters (VHF) on frogs endemic to Himalayan region to understand their ecology,” explains Dr. Muhammad Rais, Assistant Professor at the Herpetology Lab in the Arid Agriculture University, Rawalpindi, and lead author of the study. “Surprisingly, the Murree Hills Frog and Hazara Torrent Frog depend heavily for their survival on particular stream(s).”
“We suggest carrying out additional long term studies by incorporating multiple adjacent stream systems to better understand dispersal and colonization in these frogs,” he says in conclusion.

HUNTSVILLE, Ala. (June 1, 2022) – A small, rare crayfish thought to be extinct for 30 years has been rediscovered in a cave in the City of Huntsville in northern Alabama by a team led by an assistant professor at The University of Alabama in Huntsville (UAH).
Dr. Matthew L. Niemiller’s team found individuals of the Shelta Cave Crayfish, known scientifically as Orconectes sheltae, in 2019 and 2020 excursions into Shelta Cave – its only home.

Dr. Niemiller, an assistant professor of biological sciences at UAH, a part of the University of Alabama System, is co-author of a paper on the findings in the journal Subterranean Biology. Besides Dr. Niemiller, authors are UAH’s Katherine E. Dooley and K. Denise Kendall Niemiller, and Nathaniel Sturm of the University of Alabama.
The crayfish’s home is a 2,500-foot cave system that’s owned and managed by the National Speleological Society (NSS) and is unobtrusively located beneath the organization’s national headquarters in northwest Huntsville and is surrounded by subdivisions and bustling roadways.

“The crayfish is only a couple of inches long with diminutive pincers that are called chelae,” Dr. Niemiller says. “Interestingly, the crayfish has been known to cave biologists since the early 1960s but was not formally described until 1997 by the late Dr. John Cooper and his wife Martha.”
But the aquatic ecosystem, including the Shelta Cave Crayfish, crashed sometime in the early 1970s. The crash may be related to a gate that was built to keep people out of the cave and yet still allow a grey bat maternity population to still move freely in and out.
Even before the decline in the aquatic cave community, the Shelta Cave Crayfish was never common compared to the other two species, Southern Cave Crayfish (Orconectes australis) and Alabama Cave Crayfish (Cambarus jonesi).
“To the best of our knowledge, only 115 individuals had been confirmed from 1963 through 1975. Since then, only three have been confirmed – one in 1988 and the two individuals we report in 2019 and 2020,” Dr. Niemiller says.
“After a couple of decades of no confirmed sightings and the documented dramatic decline of other aquatic cave life at Shelta Cave, it was feared by some, including myself, that the crayfish might now be extinct.”
For the first time since 1988, this endemic #crayfish is confirmed to be present in the cave. The rediscovery offers optimism that other #cave and groundwater species that have not been observed in several decades may still persist. 3/4https://t.co/Efs4B0gGmZ
While it’s encouraging that the Shelta Cave Crayfish still persists, he says scientists still haven’t rediscovered other aquatic species that once lived in the cave system, such as the Alabama Cave Shrimp and Tennessee Cave Salamander.
“The groundwater level in Shelta Cave is the result of water that works its way naturally through the rock layers above the cave – called epikarst – from the surface,” says Dr. Niemiller. “However, urbanization in the area above the cave system may have altered rates at which water infiltrates into the cave and also increased rates of pollutants, such as pesticides and heavy metals entering the cave system.”
The crayfish was rediscovered during an aquatic survey aimed toward documenting all life that encountered in the cave system.
“I really wasn’t expecting to find the Shelta Cave Crayfish. My students, colleagues and I had visited the cave on several occasions already leading up to the May 2019 trip,” Dr. Niemiller says. “We would be fortunate to see just a couple of Southern Cavefish and Southern Cave Crayfish during a survey.”

While snorkeling in about 15 feet of water in North Lake located in the Jones Hall section of the cave, Dr. Niemiller spotted a smaller-sized cave crayfish below him.
“As I dove and got closer, I noticed that the chelae, or pincers, were quite thin and elongated compared to other crayfish we had seen in the cave,” he says. “I was fortunate to swoop up the crayfish with my net and returned to the bank.”
“The second Shelta Cave Crayfish that we encountered was in August 2020 in the West Lake area,” he says.
The team had searched much of the area and didn’t see much aquatic life. As they started to make their way out the lake passage to return to the surface, Nate Sturm, a master’s student in biology at the University of Alabama who had accompanied the lab for the trip, noticed a small white crayfish in an area that the team had previously walked through.
To aid identification, the team analyzed short fragments of mitochondrial DNA in the tissue samples collected.
“We compared the newly generated DNA sequences with sequences already available for other crayfish species in the region,” Dr Niemiller says. “A challenge we faced was that no DNA sequences existed prior to our study for the Shelta Cave Crayfish, so it was a bit of a process of elimination, so to speak.”
Outside of the dissertation work done by Dr. Cooper, little about the life history and ecology of the species is known.
There is, however, concern, as the species remains "critically imperiled and on the brink of extinction", because of its small population. 4/4 pic.twitter.com/zmqk9KnuGP
“Groundwater is critically important not just for the organisms that live in groundwater ecosystems, but for human society for drinking water, agriculture, etc.,” Dr. Niemiller says.
“The organisms that live in groundwater provide important benefits, such as water purification and biodegradation,” he says. “They also can act like ‘canaries in the coal mine,’ indicators of overall groundwater and ecosystem health.”
