Marine researchers have identified a vibrant new species of deep-sea precious coral off the coast of Kochi Prefecture, Japan. The new species, named Hemicorallium osmanthogemmum, was described by Tatsuki Koido from the Kuroshio Biological Research Foundation and published in the open-access journal ZooKeys.
The specimen was originally brought to the surface after being incidentally hooked at a depth of approximately 550 metres off Cape Ashizuri during longline fishing operations for alfonsino fish. Recognising its unique characteristics, the collector deposited the specimens at the Kuroshio Biological Research Foundation for further study.
Through microscopic examination of the coral’s tiny skeletal structures (called sclerites) combined with advanced multi-gene DNA analysis, the coral was confirmed to be entirely new to science, marking the first time the deep-sea genus Hemicorallium has ever been reported off Kochi Prefecture.

Resembling Sweet Olive Buds: The Etymology
The scientific name of the new species, Hemicorallium osmanthogemmum, has a beautiful meaning rooted in botany. The specific name is derived from Osmanthus (the plant genus containing the sweet olive tree) and the Latin word gemma, meaning “bud”. This name highlights a distinct physical trait of the coral: its large polyp mounds are tightly clustered together at the very tips of its branches, mirroring the appearance of flower buds on a sweet olive tree.
Reflecting this resemblance, the coral has been given the new Japanese common name Kinmokusei-mizo-sango, which translates to “sweet olive groove-coral”. In life, the coral features a striking contrast of colours; its outer living tissue is a vibrant orange, while its solid internal skeletal axis is a stunning shade of pink.
The Cultural and Environmental Value of Precious Corals
Precious corals, which primarily belong to the family Coralliidae, have been highly valued by humans for centuries. Because they possess solid inner skeletons and vivid natural colouration, they are traditionally sought after globally for crafting fine jewellery and ornaments.
In recent years, however, the global perspective has shifted significantly. Instead of viewing precious corals solely through the lens of resource consumption, modern marine science is focused heavily on developing innovative methods for propagation and active population replenishment.
Japan has a particularly deep history in this field; domestic scientific study of precious corals began in the early 20th century, and discussions regarding resource conservation through coral release programmes date back more than one hundred years, showing a long-standing cultural and scientific dedication to the sustainable management of the precious coral industry.

Why This Discovery Matters
Corals in the genus Hemicorallium live in particularly deep waters where environmental sampling is extremely challenging, therefore opportunities to study them are rare. Marine biologists believe that many more undiscovered species are still hidden across these deep seafloors.

A 23-year camera-trap study across Bolivia & Peru recorded 594 events of the elusive short-eared dog (Atelocynus microtis), shedding light on its ecological behaviour and relative abundance.
For decades, the short-eared dog (Atelocynus microtis) has been considered one of the least-known carnivores in Latin America, and potentially one of the least-known canids in the world. Because of its highly secretive nature, acute hearing, and strong sense of smell, this cryptic creature has successfully avoided people, leaving biologists with very few direct sightings in the wild. However, a new study published in the open-access journal Neotropical Biology and Conservation now offers insights into the life of this mysterious Amazonian predator.
The Power of Remote Sensing

According to the study‘s lead author Robert Wallace, the turning point in their understanding of the ghost dog came with the advent of remote sensing. When researchers first started capturing pictures of the species with camera traps back in 2001, they knew they were onto something special and envisioned a comprehensive publication.
Over the span of nearly 25 years, scientists systematized 500 distributional records across Bolivia and conducted 34 intensive camera-trap surveys. These surveys took place across the lowland regions of Bolivia and Peru, primarily in the Greater Madidi-Tambopata and Llanos de Moxos Biocultural Landscapes.
Accumulating 594 independent photographic events, this monumental effort represents the largest collection of confirmed short-eared dog records anywhere within the species’ distribution. The lead author highlighted that this research is a:
Wonderful example of how conservation technology and remote sensing – in this case the intensive use of camera traps – can provide substantial data on one of the least known species of the Amazonian rainforests.
Unveiling the Ghost

What exactly does this ghost dog look like? The camera traps revealed a unique physical profile: a dark, dense coat ranging from blackish gray to reddish-brown, a large head with very small and rounded ears, short legs, and a long, bushy tail. Intriguingly, the species even boasts partially webbed paws, a trait that is completely unique among Amazonian canids.
The biggest surprise, however, wasn’t its appearance.
The most surprising aspect of the results was that despite being an almost mythical beast, short-eared dogs are much more abundant than we had imagined.
noted the researchers.
While they are by no means a common species, their camera-trap capture rates and an estimated density of 15 individuals per 100 square kilometers suggest they are not as rare as scientists once feared. The results allowed for the researchers to determine that the short-eared dogs are more abundant than larger carnivores like jaguars, though less abundant than medium-sized carnivores like ocelots. The study also highlighted a small aspect of these canids’ behavioral ecology: they are primarily diurnal, meaning they are most active during the day, with their activity peaking between 6:00 a.m. and 12:00 p.m.
A Forest Specialist in Need of Protection
So, where are these ghost dogs hiding? The data points to intact forests. The short-eared dog is a true forest specialist, showing a strong preference for terra firme – upland forests away from rivers. This specialized, dense habitat requirement is a primary reason for the species’ reduced visibility to humans.
Because their survival is intricately tied to continuous, intact forest cover, the conservation of the short-eared dog depends heavily on the creation and effective management of protected areas. The study found that the relative abundance of short-eared dogs was noticeably higher in national protected areas and Indigenous territories that overlap with these protected zones, compared to unprotected areas.
The most important management strategy is the protection of Amazonian forest canopy for which the creation and effective management of protected areas is the most important element, in combination with the sustainable management of Indigenous territories.
the researchers explained.
While we now know that this elusive canid is secretly thriving in the deep forests of Bolivia and Peru, its future relies entirely on our ability to protect its home.

After 20 years without any visual proof, photos now published in the Neotropical Biology and Conservation journal confirm the survival of the cryptic Cozumel dwarf fox.
We at Pensoft Publishers, asked Travis Bayer, the founder of Pathos Wildlife, several questions about his work with one of the world’s most mysterious carnivores, namely the Cozumel Dwarf Fox from Cozumel Island, Mexico.
In this Q&A, Travis takes us behind the scenes of his study to discuss what first motivated him to track this cryptic species, what they currently know of its fragile conservation status, and the urgent measures needed to protect it from extinction.
Pensoft (P): What motivated your and your team to conduct research?
Travis Bayer (TB): Cozumel sits along the Great Mesoamerican Reef, the second largest reef system on Earth and one of the world’s most renowned scuba diving destinations. I first visited the island back in early 2023 to experience it for myself. At the core of my career as a biologist and conservationist is a lifelong love and fascination for animals, which is why I always look up the native wildlife and try to see them wherever I go.
That is when I had found out about Cozumel’s incredible level of endemism, higher than any other island in Mexico. Above its biodiverse waters lie terrestrial ecosystems hosting dozens of species and subspecies found nowhere else on Earth. Even more fascinating is three of them being dwarfed mammalian carnivores: the pygmy raccoon (Procyon pygmaeus), dwarf coati (Nasua nelsoni), and Cozumel fox (Urocyon sp.).
This is quite unusual given carnivores are generally less likely to become dwarfed or persist on small, resource-limited islands because of their space and energy requirements. Yet on Cozumel, this pattern occurs across multiple species.
I naively thought I might encounter the fox if I searched hard enough, but I ultimately returned home without seeing one. However, the question of whether they still persisted never really left my mind.
I turned my curiosity into an investigation, scouring scientific literature for every recorded mention of the Cozumel fox. The only physical evidence of its existence came from subfossil bones excavated from Mayan archaeological sites. These 500-to-1,500-year-old adult bones were 60-80% smaller than mainland foxes, suggesting they have been evolving in isolation for at least 5,000 to 13,000 years. This warrants a distinct species designation, yet without modern evidence, the Cozumel fox remains scientifically undescribed and legally unprotected.
The consensus of their critically endangered or possibly extinct status comes from generalized surveys documenting the other carnivores, which failed to detect the fox. While no field study has everdetected the fox, I found that none have ever targeted them specifically.
Previous camera trap studies used general baits like sardines and cat food, which heavily attract a broad range of species such as the omnivorous raccoons and coatis. Extremely rare animals also often require broader coverage, longer deployment times, and targeted placement in remote habitat, making study design crucially important. This is when I decided to turn my interest into action, and began planning the first-ever systematic, targeted survey in search of the Cozumel fox.
A scenic view of Laguna Colombia State Reserve, one of the largest remaining protected natural areas on Cozumel. The reserve is the site of historical Cozumel fox sightings recorded in 1995 and 2001, as well as the area where the first photographic evidence of the species was captured by author Rafael Chacón. As a result, it is currently considered some of the most likely remaining habitat for the Cozumel fox.
Shortly after, the ultimate driving force for our motivation surfaced: in September 2023, the first-ever photographs of a living Cozumel fox were uploaded to iNaturalist by Rafael Chacón, Director of Conservation and Environmental Education for La Fundación de Parques y Museos de Cozumel (FPMC). For a species many believed extinct, seeing those images was surreal. It proved the fox was still out there, and the urgency to protect it skyrocketed.

For a species long thought to be possibly extinct or at best extremely rare, this record provided the first visual confirmation that the fox was still persisting on the island. Credit to Rafael Chacón.
We established a partnership to launch a dedicated camera trap survey. When I asked Rafael what motivated him, he told me:
“Photographing the Cozumel gray fox was a very special moment because it represents one of the island’s unique endemic species. Capturing these images helps create awareness about its presence and the importance of protecting its habitat. What motivates me to continue is the responsibility to help future generations understand and value Cozumel’s biodiversity.”
Formally publishing these photographs in Neotropical Biology and Conservation changed this from an anecdotal sighting into a permanent scientific record. Species cannot be protected if their existence remains contested or overlooked. We hope this work lays the foundation for future research, conservation planning, and official taxonomic recognition.

P: You describe the species’ conservation status as “likely critical.” What are the biggest threats to the Cozumel fox today?
TB: The biggest challenge is that we still know almost nothing about its population size, distribution, or ecology. That uncertainty makes effective conservation incredibly difficult, and the lack of a formal taxonomic description limits our ability to implement legal protections.

Chacón, unpublished data 2025; Bayer and McGreal, unpublished data 2026). Credit to Bayer et al., 2026.
However, based on what we know about island ecosystems, several major threats stand out:
Habitat Loss & Fragmentation: Rapid development driven by tourism, cruise ship infrastructure, and expanding hotels places immense pressure on remaining natural habitats.
The Coastal Highway: Cozumel has one major highway looping the island that cuts directly through critical transition zones between coastal and interior habitats. Wildlife-vehicle collisions occur at alarming rates. This poses a massive threat to carnivores who need to move freely to maintain genetic connectivity, find resources, and adapt to seasonal water availability.
Introduced & Invasive Species: Free-ranging domestic dogs compete for resources and introduce deadly disease risks to a small, isolated population. Concurrently, invasive predators like boa constrictors, margays, and ocelots create intense pressure through competition and direct predation. The growing abundance of introduced margays and ocelots is a relatively recent, alarming concern.
Climate Change & Rarity: As a low-lying Caribbean island, Cozumel is highly vulnerable to intensifying hurricanes and storm surges. Because the fox population is already so small, they are inherently vulnerable to genetic bottlenecks and random catastrophic events.
P: What conservation measures could be undertaken to help protect the species?
TB: The most urgent priority is establishing a long-term research and monitoring program focused specifically on the fox. Before we can implement meaningful protections, we must understand exactly where they survive, how many are left, and what habitats they depend on.
A deceased dwarf coati (Nasua nelsoni), one of Cozumel’s three endemic carnivores, found along the coastal highway after a vehicle collision. As this road cuts through critical habitat transitions, wildlife-vehicle collisions remain a major conservation concern, particularly for species that depend on landscape connectivity between coastal and interior ecosystems.
To achieve these goals, we must prioritize mitigating road mortality by installing dynamic speed feedback signs to slow highway traffic and improve habitat connectivity. Additionally, we need to manage invasive and domestic animals through responsible pet ownership, sterilization programs, and the removal or relocation of invasive predators like margays to minimize disease and predation risks. Finally, because conservation is a collective responsibility, we must foster robust community involvement and public awareness to educate residents and visitors about the Cozumel fox, thereby securing the local support and cooperation vital for these measures to succeed.
Captured during the most recent camera trap deployment on Cozumel, this image documents a Margay (Leopardus wiedii), an introduced carnivore on the island. Its presence adds to growing concerns about non-native and expanding predator populations, and their potential to intensify competition and predate on Cozumel’s endemic wildlife.
P: Are there any other comments or insights from this research that you think might be of particular importance to the broader public?
TB: One of the most important takeaways from this research is that species can quietly disappear without the world even realizing they are gone. It had been over 20 years since the last anecdotal report of the fox, and almost 30 years since the last confirmed sighting. The Cozumel fox likely represents an ancient island lineage that has evolved in isolation for thousands of years, yet until recently there was no photographic evidence that it was even still alive.
“Their life depends on you. Drive with caution.” A message displayed on author Rafael Chacón’s vehicle, serving as a reminder that Cozumel’s wildlife shares the same roads. Vehicle collisions remain a significant source of mortality on the island, making public awareness a key part of conservation efforts.
We often think extinction is something dramatic and obvious, but in reality it can happen gradually and silently, especially for rare species living in remote or understudied habitats. By the time enough data exists to confirm a severe decline, it may already be too late. That is part of what makes documentation like Rafael’s photos so important. It should serve as a reminder of how much biodiversity can still remain overlooked, even in places visited by millions of people every year.

The rediscovery of the fox isn’t a conservation success story yet, but it is a second chance.
In collaboration with Pathos Wildlife and the FPMC, we are currently conducting one of the largest camera trap surveys ever done on the island. Ultimately, we hope this work moves the Cozumel fox from a little-known, uncertain presence to a protected, well-understood key part of Cozumel’s ecosystems. This project demonstrates that conservation is often most urgent when certainty is lowest, and that uncertainty itself should be our call to action.
We are incredibly grateful to Travis Bayer for giving us a closer look at his and his team’s vital conservation work on the island. To read the formal scientific record and documentation of these historic sightings, check out the recently published paper in Neotropical Biology and Conservation.

The newly described aquatic insects, belonging to the genus Hydropsyche, help close substantial knowledge gaps regarding the biodiversity of Azerbaijan, Iran, and Türkiye. Caddisflies (order Trichoptera) are vital components of freshwater ecosystems, and the Hydropsyche genus is among the most diverse and ecologically important, comprising more than 8% of all Trichoptera species recorded in the Western Palaearctic region.
The Two New Caddisfly Species

Both new species were found in habitats characterized by stone, pebble, and fine sediments with sparse riparian vegetation. Hydropsyche fitesa was discovered in Iran, specifically near the Shalmash Waterfalls on the Chamyaman River, a tributary originating in the Zagros Mountains; the epithet fitesa honors the first author’s wife, in recognition of her lifelong support of caddisfly research. Hydropsyche hindrajab was found across multiple river localities in Azerbaijan, Iran, and Türkiye, and was named in honor of Hind Rajab, a five-year-old girl whose life was lost amid the Israeli-Palestinian conflict.
Authored by Halil Ibrahimi (University of Prishtina, Kosovo) and Dora Hlebec (University of Zagreb, Croatia), the study highlights the challenges of identifying morphologically similar species. Because both new insects belong to the Hydropsyche guttata species cluster, a group whose members look strikingly alike, the team employed an integrative taxonomic approach.
By combining traditional morphological examination with advanced DNA analysis (specifically, sequencing of the mitochondrial cytochrome c oxidase subunit I, or COI gene), the researchers confirmed that H. hindrajab represents a distinct evolutionary lineage. H. fitesa was distinguished based on unique morphological differences in its physical structure compared to its closest relatives.
Future Explorations

The discovery underscores how much of the region’s aquatic life remains undocumented. The authors note that the type localities in West Azerbaijan Province, Iran, are known for harboring rare aquatic insects, and they believe the area likely holds additional undescribed species yet to be found. Currently, 23 Hydropsyche species are known in Iran, 67 in Türkiye, and 12 in Azerbaijan, but the potential for new discoveries remains high.

A new study published in the open-access Biodiversity Data Journal suggests that spider webs – particularly those incorporating environmental debris – can serve as natural, non-destructive collectors of fungal material in agricultural ecosystems. The findings show that viable fungi can be recovered from these structures, including lineages that may represent previously undocumented diversity.
“Spider webs are often overlooked structures in the environment, yet they can function as natural collectors of biological material. Our findings suggest that they can be used as a complementary approach to access microbial communities without disturbing the surrounding ecosystem.”
Thanakron Into (Student at Thammasat University)
Researchers from Thammasat University and the National Center for Genetic Engineering and Biotechnology (BIOTEC), Thailand, investigated whether the adhesive and particle-trapping properties of spider silk could be used to capture and culture fungi associated with airborne and environmental particles. Unlike DNA-based methods, which detect genetic material regardless of viability, this approach allows for the recovery of living organisms that can be further studied.
The study focused on tropical rice fields, using webs of the orb-weaving spider Cyclosa mulmeinensis, a species known for constructing distinctive “trashline” decorations – linear accumulations of plant fragments, insect remains, and other debris within the web. These structures can intercept a variety of particles, some of which may carry fungal propagules.

Webs were collected from rice-field embankments in Pathum Thani, Nakhon Nayok, and Phetchaburi provinces using sterile techniques. In the laboratory, material retained on the silk was gently removed and cultured, yielding 112 viable fungal isolates. These isolates were grouped into 23 taxa across six genera, including Alternaria, Aspergillus, Cladosporium, Fusarium, Penicillium, and Talaromyces.
“We were particularly surprised that many of the fungi recovered from the webs remained viable and could be cultured. This enables further investigation beyond presence or absence, including their biological characteristics.”
Thanakron Into

Some genetic lineages – particularly within Cladosporium and Talaromyces – did not match currently described species in available databases, indicating that additional, undocumented diversity may be present in these systems.
Conventional approaches to fungal monitoring typically rely on soil, air, or plant sampling, or on molecular methods that may not distinguish between living and non-living material. In this context, spider webs may provide a useful supplementary sampling surface for capturing biologically relevant particles.
Because spider webs are naturally maintained and, in some species, periodically rebuilt, this method can be applied with minimal disturbance to both the organisms and their environment. Importantly, the spiders themselves were not harmed during sampling, as only small sections of the web were collected.
“The ability to recover living fungi from these naturally occurring structures adds a practical dimension to biodiversity studies. It provides a way to link environmental sampling with downstream biological work.”
Thanakron Into
The idea that something as familiar as a spider web could quietly capture a hidden layer of biodiversity highlights how much of the natural world remains overlooked in plain sight.
While further work is needed to evaluate how broadly this approach can be applied, the study demonstrates the potential of spider webs as an additional tool for exploring microbial diversity in agricultural landscapes.

Despite the intensity of modern exploration, the eastern Mediterranean continues to yield unexpected discoveries. On the small Greek island of Kastellorizo, researchers have documented a previously unknown cave cricket thriving within a network of man-made tunnels.
The species, named Dolichopoda balrogi, was described by researchers from Greece and published in the open-access Journal of Orthoptera Research. This discovery highlights how even small and seemingly ordinary habitats can shelter unique and previously unknown life.

A mysterious cricket in underground tunnels
The new species belongs to the genus Dolichopoda, a group of cave crickets that inhabit dark, humid environments such as caves, crevices, and underground spaces across southern Europe and the eastern Mediterranean. These insects are well known to evolutionary biologists because their isolated populations often evolve into distinct species on islands or in separate cave systems.
On the easternmost Greek island of Kastellorizo, researchers surveyed an artificial tunnel that serves as the island’s sole accessible land cave. To their surprise, they encountered a population of cave crickets bearing characteristics of the cave-dwelling genus Dolichopoda.
Detailed morphological and molecular study confirmed that the specimens represented a species new to science.

Why “balrogi”?
The species name balrogi was inspired by the Balrog, a legendary fire-demon from J.R.R. Tolkien’s The Lord of the Rings. In Tolkien’s story, the Balrog is an ancient creature hidden deep beneath the mountains, emerging from darkness. Its discovery is a fitting parallel; the cricket’s preference for deep, dark tunnel systems kept it outside the known record for decades.
The name also alludes to the circumstances of discovery of the species, which was found exclusively in a man-made tunnel. In Tolkien’s narrative, the Balrog is revealed only after the Dwarves “delved too deep”; similarly, Dolichopoda balrogi was discovered on Kastellorizo due to anthropogenic excavation on Mount Vigla, as the island lacks accessible caves. The epithet thus symbolically links deep excavation with the revelation of hidden subterranean fauna.
Fortunately, unlike Tolkien’s fearsome creature, Dolichopoda balrogi is harmless – although equally well adapted to life in darkness.
Hidden biodiversity in unexpected places
Kastellorizo is a very small island, covering only about 9 square kilometers. Yet its position in the eastern Mediterranean between Asia and Europe makes it an important biogeographic hotspot.
The discovery of D. balrogi demonstrates that even small islands can host unique endemic species. It also suggests that artificial underground environments, such as tunnels and abandoned infrastructure, can function as refuges for specialised cave-dwelling organisms.
“These findings remind us that biodiversity discoveries are not limited to remote tropical forests or deep oceans. Even familiar landscapes and human-made structures can harbour species that have remained unnoticed.”
Konstantinos Kalaentzis
Protecting small and fragile ecosystems
Cave-adapted organisms like Dolichopoda crickets often have very restricted distributions, sometimes occurring in only a single cave or underground system. Because of this, they can be particularly vulnerable to habitat disturbance. The authors suggest that documenting and understanding these hidden species is an important first step toward their conservation.

As research continues across the Mediterranean, the researchers note that the countless Greek islands – many still poorly explored biologically – are likely to hold many more hidden biodiversity treasures awaiting discovery.

What if some of the most important clues about marine biodiversity were already collected but never fully shared?
That’s the question that motivated this study, published in Biodiversity Data Journal. It brought together over 40 years of unpublished data on marine amphipods – ecologically crucial crustaceans – from across Italian waters. By unifying scattered records and making them openly accessible, researchers have assembled comprehensive and up-to-date inventories of these species for the Mediterranean.

Researchers analysed 4,344 previously unpublished records spanning from 1980 to 2025, identifying 302 amphipod species across the Adriatic, Tyrrhenian, and Ionian Seas. Interestingly, they found that the Tyrrhenian Sea harbours the highest taxonomic richness (258 species), while the Adriatic Sea accounts for the greatest number of records due to intense historical sampling.

This work not only updates the Italian inventory but also reinforces the country’s central role as a biodiversity hotspot in the Mediterranean.

Why amphipods matter

Amphipods are small, often just a few millimeters long, but they play an outsized role in marine ecosystems. They recycle nutrients, connect food webs, and serve as prey for fish, birds, and mammals. Because they respond quickly to environmental stress, they are also powerful bioindicators, helping scientists detect pollution and ecological changes.
Yet despite their importance, our knowledge of where these species live has been fragmented. In some cases, outdated or incomplete records have even led to cascading misidentifications in the scientific literature.

This study represents a collective effort coordinated under the National Biodiversity Future Center (NBFC). Researchers from universities, environmental agencies, and research institutes across Italy contributed data spanning more than four decades.
By harmonizing these datasets under the FAIR principles (Findable, Accessible, Interoperable, Reusable), we ensured that the information was not only scientifically robust but also openly available for future research.
commented the first author of the study, Dr. Antonina Badalucco (Dept. DiSTeM, University of Palermo).
The full dataset is now accessible via the Global Biodiversity Information Facility (GBIF), making it a resource for scientists worldwide.

The presence of non-indigenous species is a reminder that marine ecosystems are rapidly evolving. The study identified 11 alien species primarily concentrated in ports, lagoons such as the Venice Lagoon, and aquaculture facilities. Increased shipping, aquaculture, and global connectivity are allowing these species to travel farther and establish themselves in new environments, sometimes with significant ecological consequences.
At the same time, researchers observed that sampling efforts have intensified dramatically in the last decade, driven in part by European environmental policies such as the Marine Strategy Framework Directive – generating a surge in available data, while also highlighting how much earlier information had remained underused.
Why this matters now
Understanding where species live is the foundation of conservation. Without accurate distribution data, it’s nearly impossible to track biodiversity loss, identify vulnerable habitats, or design effective protection strategies.
Prof. Lo Brutto explained
By filling long-standing gaps in knowledge, this research supports broader efforts – such as the EU’s and National Biodiversity Future Centre’s shared goal to protect 30% of land and sea by 2030 – and provides a baseline for monitoring future environmental change.
Looking ahead
This is not the end of the story; it’s a starting point. Our study shows the immense value of unlocking existing data and making it accessible. We hope it will inspire similar efforts across other regions and taxonomic groups, helping to build a more complete picture of life in our oceans.

Published in ZooKeys, a recent study revises the Himalayan pit viper group using a combination of fresh and historical DNA, morphology, skeletal anatomy, and ecological observations.
The high mountain ranges of Asia remain among the least biologically explored regions of the continent. Now, an international team of researchers has shown that one of their most elusive venomous snakes, long treated a single species, is in fact a complex of five distinct species, three of which are new to science.
Published in the open-access journal ZooKeys, the study revises the Himalayan pit viper group using a combination of fresh and historical DNA, morphology, skeletal anatomy, and ecological observations. The data reveals that what scientists had long treated as a single widespread species, the Himalayan pit viper first described in 1864, actually consists of multiple deeply distinct evolutionary lineages.
The analyses identified five clearly distinct species-level lineages, i.e. the Himalayan pit viper in the strict sense, Gloydius chambensis described in 2022, and three previously unrecognised species from different parts of Pakistan and Nepal. Alongside genetic divergence, these lineages exhibit distinct morphologicalandskeletal variations.

“These mountain systems still harbour overlooked vertebrate diversity and hold important clues to the biogeography of Asia,” says Daniel Jablonski of Comenius University Bratislava, who has been conducting extensive research in Pakistan and Afghanistan for many years.
“By combining modern field sampling with data from historical museum specimens, we uncovered evolutionary lineages that had remained hidden for more than a century after the original description of the Himalayan pit viper.”
Daniel Jablonski
A key element of the discovery was the integration of newly collected material with a powerful source of evidence: DNA extracted from museum specimens collected in the 19th and early 20th centuries. This included the original type specimen of the Himalayan pit viper, allowing the researchers to clarify the identity of the species in its strict scientific sense.
The study underscores the enduring scientific value of natural history collections. Indeed, specimens gathered by earlier generations of explorers and preserved in museums are still helping scientists solve modern biological puzzles, especially in regions where fieldwork remains difficult.

In fact, part of the discovery had been waiting in plain sight. “Museum specimens are not just records of the past. They are active research tools and essential infrastructure for future science,” says Sylvia Hofmann from the Museum Koenigas part of theLeibniz Institute for the Analysis of Biodiversity Change, who has comprehensively worked in the Himalaya and Tibetan Plateau during the past 20 years.
“Some of the key evidence had been sitting in museum collections for more than a hundred years. We just didn’t have the tools to recognise it. As analytical methods continue to improve, the scientific value of these collections will only grow and revealing biodiversity we didn’t even know was there.”
Sylvia Hofmann
Representatives of the herpetofauna play an important role in the ecosystem, particularly as ecological indicators, within the food chain, and as predators in pest control. A group of top predators in the region consist of pit vipers adapted to mountainous environments, which have so far been studied only very inadequately in the Himalayan region.
“Our work aims to close these gaps in knowledge and to lay the groundwork and provide inspiration for further, in-depth studies on this ecologically and medically relevant group.”
Tillack maintains close ties with Nepalese colleagues and has been collaborating with them for 35 years on projects concerning the biodiversity of herpetofauna in the Himalaya.

The study also emphasises how much remains to be discovered in regions that have long been difficult to access for scientific research. “Pakistan’s high mountains are still full of biological surprises,” says Rafaqat Masroor of the Pakistan Museum of Natural History, the country’s leading herpetologists.
“This finding highlights how little we still know about a region long shaped by socio-political instability.”
Rafaqat Masroor
Beyond taxonomy, the findings also carry an important conservation message:
“Each of the newly recognised species seems to occupy a relatively restricted range in fragile mountain environments, highlighting new ecological and evolutionary questions.”

Without recognising such diversity, it would be impossible to assess it accurately or protect it effectively.

Invisible to the naked eye, phytoplankton play a critically important role at the base of marine food webs, yet their diversity continues to be underestimated. Recently, the UN Global Compact released “The Plankton Manifesto,” highlighting how these microscopic organisms are crucial for addressing the “triple planetary crisis” of climate change, biodiversity loss, and pollution. Diatoms, a major group of photosynthetic microalgae, are particularly powerful in driving roughly 20% of global photosynthesis and forming the very base of marine food webs.
Yet despite their monumental importance, microalgal ecosystems remain largely unexplored and poorly mapped. That is why a recent major scientific undertaking in the Northeast Pacific is so significant.
A First-of-its-Kind Baseline in the Salish Sea

Diatom records of the Salish Sea bioregion have historically been fragmentary, dating back to early inventories in the 1800s, and with only scattered surveys filling the gap across the 20th and 21st centuries. As Andrew Simon, PhD student at the University of Alberta, president of IMERSS, and one of the study’s researchers, puts it:
The Salish Sea has long been studied for its rich marine biodiversity. Yet, until now, the history of research on its primary producers has been fragmented, and we have lacked a consolidated baseline record.
Now, for the first time, researchers have taken a significant step toward closing that gap. A team of Canadian researchers — Mark Webber (University of Victoria; IMERSS), Elaine Humphrey (UVic; IMERSS), Arjan van Asselt (IMERSS), Alice Chang (UBC), Evan Morian (Hakai Institute; UBC), and Andrew Simon (IMERSS; University of Alberta) — has published anew checklist of 924 diatom taxa alongside a curated dataset of 11,469 records in the open-access journal Biodiversity Data Journal, providing a long-needed foundation for environmental monitoring across this region of the northeast Pacific Ocean.

The findings include some curious discoveries. Several taxa are reported for the first time on the Pacific coast of North America, including Trigonium quinquelobatum, while others, such as Cocconeis kerguelensis (previously known only from the Indian Ocean) and Neocalyptrella robusta (previously confined to California), suggest a range expansion into cooler waters.
Ecologically, the genus Tabularia stands out as a dominant presence on eelgrass and macroalgae, despite having few species. In contrast, genera like Auliscus, Biddulphia, and Mastogloia are surprisingly scarce in the Salish Sea compared to other regions, leaving open questions about what limits their occurrence there.
This dataset also directly answers a key recommendation from the UN Plankton Manifesto, which urges the scientific community to strengthen plankton research and develop comprehensive plankton atlases to biomonitor the health of marine ecosystems.

The Salish Sea — the traditional territory of the Coast Salish peoples — is home to roughly nine million people and is experiencing rapid growth in urbanization, industrial activity, and marine shipping.
Because diatom populations respond quickly to changes in water quality and environmental conditions, they serve as highly effective early-warning bioindicators for shifts in ecosystem health and pollution levels.
Without a clear picture of what the base of the food web looks like today, it is impossible to understand the impact of tomorrow’s environmental changes.

“We are fortunate to have had a dedicated group of academic researchers and community scientists contribute to this work over many years,” says Mark Webber, IMERSS’ resident diatomist. “Drawing from the literature, microscope analysis, and molecular sequencing, we now have a better picture of the diatoms present in the Salish Sea. Diatoms are vital to the health of countless organisms — from shorebirds and shellfish to fish and mammals. This baseline provides a reference point for understanding changes that could ripple across the entire web of life.“
Local Research for Global Solutions

The UN Plankton Manifesto stresses that understanding and managing plankton communities can unlock “Plankton-Based Solutions” to support fisheries, clean waters, and climate change mitigation.
Our work demonstrates how sustained collaboration between community scientists and research institutes can bridge these gaps, through partnering community expertise and observation with access to microscopy and molecular technologies,
the team concludes.
The new checklist and dataset will support researchers and policymakers in environmental assessments of the Salish Sea, as the team continues to refine and analyze the data to support ongoing regional research.
