Researchers who captured footage of dog attacks on endangered mountain tapirs in Colombia are calling for action to protect threatened wildlife.
Using camera traps, a team from WILD Campo Silvestre, the Tiger Cats Conservation Initiative, and the Fundación Caipora captured images of two attacks in the Campoalegre Soil Conservation District, Santa Rosa de Cabal in a period of two months.

The cameras caught domestic dogs (Canis lupus familiaris) chasing and attacking mountain tapirs (Tapirus pinchaque) in a protected area of the Central Andes. These images were subsequently published in a research paper published by the open-access journal, Neotropical Biology and Conservation.
The study offers insights into the impact of domestic dogs on wildlife, particularly on species of conservation concern such as the mountain tapir. The authors highlight the urgent need for population management and control of domestic dogs inside and around protected areas.

Conservationists recently implemented measures such as neutering and vaccination programs for stray and owned dogs in the vicinity of natural reserves to protect the threatened clouded tiger cat (Leopardus pardinoides) in the region. The research team call for these measures to be extended to WILD Campo Alegre and surrounding lands.

“Domestic dog incursion into protected areas is a global threat to wildlife that is difficult to mitigate because of the inherent social dilemma of controlling dog populations,” says Juan Camilo Cepeda-Duque, lead author of the study.
“Dogs can contribute to the extinction of vertebrate species, can imbalance the trophic dynamics amongst predator guilds and even have the potential to collapse entire ecological communities,” he continues.
The mountain tapir is an emblematic herbivore of the Andean cloud forest, globally classified as ‘Endangered’ according to the IUCN Red List due to habitat loss and poaching. The presence and aggressive behaviour of domestic dogs not only threaten the physical wellbeing of these tapirs but also their reproductive performance, foraging efficiency, and overall population health due to increased stress, potential for disease transmission, and alterations in habitat use.
The research team highlight that their observations are not isolated cases, as locals previously reported the same dogs chasing and attacking mountain tapirs and cattle. The conservationists are also concerned that they detected no juvenile mountain tapirs in the survey.

The NGO WILD Nature Foundation has established a new protected area in the northern extreme of the Campoalegre Soil Conservation District, with the target of protecting the habitat of endangered mountain tapirs and the last remnant populations of the fuerte’s parrot (Hapalopsittaca fuertesi) in the region. Currently, the reserve is carrying out an unprecedented restoration program, planting thousands of trees to recover the land once cleared for the establishment of cattle ranching.

Over the last few years, professor Halil Ibrahimi from Kosovo and his team have described several new species of aquatic insects revered as bioindicators of freshwater ecosystems. However, the celebration of these discoveries is tempered by alarming concerns: the newfound species are often already considered endangered, as per the criteria set forth by the International Union for Conservation of Nature (IUCN), as soon as they are described. This classification underscores the urgent need for conservation efforts to safeguard their existence.
The research team just discovered a new species, named Potamophylax kosovaensis, in the spring area of the Llap River, nestled within the Ibër River Basin. The region, known for its ecological significance, serves as a critical habitat for numerous aquatic organisms like newly discovered insect species.

Unfortunately, these freshwater insects are facing unprecedented threats in Kosovo and the broader Balkans region. Anthropogenic pressures, such as water pollution, littering, and the construction of hydropower plants, pose imminent risks to their survival. The degradation of their habitats not only jeopardizes their existence, but also undermines the health and integrity of entire freshwater ecosystems.

Professor Ibrahimi emphasizes on the importance of urgent action to mitigate these threats and conserve this delicate balance of freshwater biodiversity. “The discovery of Potamophylax kosovaensis serves as a stark reminder of the fragility of our freshwater ecosystems,” he states. “We must prioritize efforts to protect these habitats and the invaluable species they harbor.”

Its name pays homage to the dark wizard Lord Voldemort, the fearsome antagonist of the Harry Potter series, drawing parallels with the ant’s ghostly appearance.
In the sun-scorched Pilbara region of north-western Australia, scientists have unearthed a mysterious creature from the shadows – a new ant species of the elusive genus Leptanilla.
The new species, Leptanilla voldemort – L. voldemort for short – is a pale ant with a slender build, spindly legs, and long, sharp mandibles. The species name pays homage to the dark wizard Lord Voldemort, the fearsome antagonist of the Harry Potter series, drawing parallels with the ant’s ghostly and slender appearance, and the dark underground environment, from which it has emerged.
Leptanilla voldemort was discovered during an ecological survey to document animals living belowground in the arid Pilbara region of north-western Australia. Only two specimens of the bizarre new ant species were found. Both were collected in a net that was lowered down a 25-metre drill hole and skilfully retrieved while scraping against the hole’s inner surface – an innovative technique for collecting underground organisms known as ‘subterranean scraping’.
A general landscape of the Pilbara region.
Compared to other Leptanilla antspecies, L. voldemort has an extremely slender body as well as long, spindly antennae and legs. Together with its collection from a 25-metre-deep drill hole, this unusual morphologyhas left experts speculating as to whether it truly dwells in soil like other Leptanilla species, or exploits a different subterranean refuge, such as the air-filled voids and cracks that form within layers of rock deeper underground.
Leptanilla voldemort.
The long, sharp jaws of L. voldemort, however, leave little to the imagination.
“Leptanilla voldemort is almost surely a predator, a fearsome hunter in the dark. This is backed up by what we know from the few observations of specialised hunting behaviours in other Leptanilla antspecies, where the tiny workers use their sharp jaws and powerful stings to immobilise soil-dwelling centipedes much larger than them, before carrying their larvae over to feed on the carcass” said Dr Wong, lead author of the study.
A full-face view of Leptanilla voldemort, showing its sharp mandibles.
The exact prey of L. voldemort, however, is not known, though a variety of other subterranean invertebrates, including centipedes, beetles and flies, were collected from the same locality.
There are over 14,000 species of ants worldwide, but only about 60 belong to the enigmatic genus Leptanilla. Unlike most ants, all species of Leptanilla are hypogaeic – their small colonies, usually comprising a queen and only a hundred or so workers, nest and forage exclusively underground. To adapt to life in darkness, Leptanilla workers are blind and colourless. The lilliputian members of the ant world, these ants measure just 1 to 2 millimetres – not much larger than a grain of sand – allowing them to move effortlessly through the soil. Due to their miniscule size, pale colouration, and unique underground dwellings, finding Leptanilla species is a challenge even for expert ant scientists, and much of their biology remains shrouded in mystery.
While Australia boasts some of the highest levels of ant diversity in the world – with estimates ranging from 1,300 to over 5,000 species – L. voldemort is only the second Leptanilla species discovered from the continent. The first, Leptanilla swani, was described nearly a century ago – from a small colony found under a rock in 1931 – and has almost never been seen since.
With its formation beginning approximately 3.6 billion years ago, the Pilbara is one of the oldest land surfaces on Earth. Despite the scorching summers and meagre rainfall, the region harbours globally important radiations of underground invertebrates. Adding to the unique biodiversity of this ancient landscape, the discovery of the enigmatic ant L. voldemort is a testament to the wizardry of nature and the mysteries of life in the depths of darkness.

The papillated redbait is a member of the family Emmelichthyidae. There are only 18 known species in this family, which are commonly called redbaits, rovers, or rubyfishes. These deepwater species can be found in warm, tropical waters and are usually bright shades of red, orange, and pink.
How did Bemis and her team make this remarkable discovery? To find out, we’ll have to first travel to a fish market in the Philippines.
A molecular mystery
As part of an interagency campaign to create a reference library of fish DNA “barcodes,” Bemis and her colleagues regularly travel abroad to collect fish specimens. Some come from seafood markets overseas where they are being sold for food. In the field, these new specimens are assigned a preliminary species identification. Then, they’re transported to the Smithsonian Institution and National Systematics Laboratory for genetic sequencing, data collection, and a secondary species confirmation.

Since getting involved with this project in 2021, Bemis and teammate Dr. Matthew Girard of the Smithsonian National Museum of Natural History have analyzed thousands of samples. None have made a bigger splash, though, than two small pink fish collected from a Philippine fish market on the island of Cebu.
While collecting data from these specimens, Girard made an exciting observation. Their genetic sequences did not match their initial species identification as golden redbaits—or any other species in the genetic library, for that matter. So which species did Girard and Bemis have on their hands?

In search of answers, Bemis and Girard examined other aspects of the specimens’ biology, including their anatomy. They discovered that these fish differed from the golden redbait in several ways, including:
A different number of gill rakers, structures inside the mouth that help fish to feed
A different number of pectoral fin rays
Two fleshy structures called papillae on the pectoral girdle
These differences, combined with the genetic data, provided evidence that the two specimens were not golden redbaits, but a previously undiscovered species. With only two confirmed specimens, Bemis and Girard wondered if other individuals could be identified in global natural history collections.

After some detective work, Bemis and Girard spotted a third specimen they hypothesized might also be the undescribed species. A fish with similar color also identified as a golden redbait had been collected from a fish market in the Philippines by the Kagoshima University Museum in Japan. Bemis and Girard studied the specimen and confirmed their hypothesis with genetic and anatomical data. This specimen became the third record of papillated redbait and, ultimately, the holotype for the species—the specimen upon which a new species description is based.
More to discover
Even after describing new species, there’s always more to learn. Bemis and Girard are energized that there is still much to discover about the papillated redbait and the redbait family, which is relatively poorly known. Any opportunity to add to this small body of knowledge and study redbait species in greater detail is valuable. “I’ve had researchers that work on fish taxonomy say to me, ‘I didn’t even know this family existed.’ That’s how little we know about this group,” Girard emphasizes.
Bemis also notes that because data on the papillated redbait comes from only three specimens purchased in fish markets, she still has lots of questions. For example, Bemis says that they don’t yet know if the new species occurs outside Philippine waters, or the exact habitat in which they occur. “We also don’t know anything about their reproduction or what they eat—really basic aspects of their biology remain to be studied. Now that we recognize that it is different, we only have more to study as new specimens of papillated redbait are collected,” Bemis says.
“It is always a happy and productive moment working with U.S. scientists,” says Dr. Mudjekeewis “Mudjie” Santos of the Philippine National Fisheries Research and Development Institute. Santos was instrumental in the collection of specimens, providing fisheries data on the papillated redbait, and coining a name for the new species in Tagalog, the national language of the Philippines.

One thing is for certain, though. There are more species just waiting to be discovered, and they might be right under our noses. “I think the craziest thing is that the papillated redbait is a new species that came from a market,” Girard says. “The fact that there are undescribed species being sold without us even realizing it underscores how much we still have to learn about marine biodiversity.”

Leiden – also known as the ‘City of Keys’ and the ‘City of Discoveries’ – was aptly chosen to host the third Empowering Biodiversity Research (EBR III) conference. The two-day conference – this time focusing on the utilisation of biodiversity data as a vehicle for biodiversity research to reach to Policy – was held in a no less fitting locality: the Naturalis Biodiversity Center.
On 25th and 26th March 2024, the delegates got the chance to learn more about the latest discoveries, trends and innovations from scientists, as well as various stakeholders, including representatives of policy-making bodies, research institutions and infrastructures. The conference also ran a poster session and a Biodiversity Informatics market, where scientists, research teams, project consortia, and providers of biodiversity research-related services and tools could showcase their work and meet like-minded professionals.
BiCIKL stops at the Naturalis Biodiversity Center
The main outcome of the BiCIKL project: the Biodiversity Knowledge Hub, a one-stop knowledge portal to interlinked and machine-readable FAIR data.
The famous for its bicycle friendliness country also made a suitable stop for BiCIKL (an acronym for the Biodiversity Community Integrated Knowledge Library): a project funded under the European Commission’s Horizon 2020 programme that aimed at triggering a culture change in the way users access, (re)use, publish and share biodiversity data. To do this, the BiCIKL consortium set off on a 3-year journey to build on the existing biodiversity data infrastructures, workflows, standards and the linkages between them.
Many of the people who have been involved in the project over the last three years could be seen all around the beautiful venue. Above all, Naturalis is itself one of the partnering institutions at BiCIKL. Then, on Tuesday, on behalf of the BiCIKL consortium and the project’s coordinator: the scientific publisher and technology innovator: Pensoft, Iva Boyadzhieva presented the work done within the project one month ahead of its official conclusion at the end of April.
As she talked about the way the BiCIKL consortium took to traverse obstacles to wider use and adoption of FAIR and linked biodiversity data, she focused on BiCIKL’s main outcome: the Biodiversity Knowledge Hub (BKH).
Key results from the BiCIKL project three years into its existence presented by Pensoft’s Iva Boyadzhieva at the EBR III conference.
Intended to act as a knowledge broker for users who wish to navigate and access sources of open and FAIR biodiversity data, guidelines, tools and services, in practicality, the BKH is a one-stop portal for understanding the complex but increasingly interconnected landscape of biodiversity research infrastructures in Europe and beyond. It collates information, guidelines, recommendations and best practices in usage of FAIR and linked biodiversity data, as well as a continuously expanded catalogue of compliant relevant services and tools.
At the core of the BKH is the FAIR Data Place (FDP), where users can familiarise themselves with each of the participating biodiversity infrastructures and network organisations, and also learn about the specific services they provide. There, anyone can explore various biodiversity data tools and services by browsing by their main data type, e.g. specimens, sequences, taxon names, literature.
While the project might be coming to an end, she pointed out, the BKH is here to stay as a navigation system in a universe of interconnected biodiversity research infrastructures.
To do this, not only will the partners continue to maintain it, but it will also remain open to any research infrastructure that wishes to feature its own tools and services compliant with the linked and FAIR data requirements set by the BiCIKL consortium.
Indisputably, the ‘hot’ topics at the EBR III were the novel technologies for remote and non-invasive, yet efficient biomonitoring; the utilisation of data and other input sourced by citizen scientists; as well as leveraging different types and sources of biodiversity data, in order to better inform decision-makers, but also future-proof the scientific knowledge we have collected and generated to date.
Project’s coordinator Dr Quentin Groom presents the B-Cubed’s approach towards standardised access to biodiversity data for the use of policy-making at the EBR III conference.
Amongst the other Horizon Europe projects presented at the EBR III conference was B-Cubed (Biodiversity Building Blocks for policy). On Monday, the project’s coordinator Dr Quentin Groom (Meise Botanic Garden) familiarised the conference participants with the project, which aims to standardise access to biodiversity data, in order to empower policymakers to proactively address the impacts of biodiversity change.
You can find more about B-Cubed and Pensoft’s role in it in this blog post.
Dr France Gerard (UK Centre for Ecology & Hydrology) talks about the challenges in using raw data – including those provided by drones – to derive habitat condition metrics.
MAMBO: another Horizon Europe project where Pensoft has been contributing with expertise in science communication, dissemination and exploitation, was also an active participant at the event. An acronym for Modern Approaches to the Monitoring of BiOdiversity, MAMBO had its own session on Tuesday morning, where Dr Vincent Kalkman (Naturalis Biodiversity Center), Dr France Gerard (UK Centre for Ecology & Hydrology) and Prof. Toke Høye (Aarhus University) each took to the stage to demonstrate how modern technology developed within the project is to improve biodiversity and habitat monitoring. Learn more about MAMBO and Pensoft’s involvement in this blog post.
MAMBO’s project coordinator Prof. Toke T. Høye talked about smarter technologies for biodiversity monitoring, including camera traps able to count insects at a particular site.
On the event’s website you can access the MAMBO’s slides presentations by Kalkman, GerardandHøye, as presented at the EBR III conference.

The EBR III conference also saw a presentation – albeit remote – from Prof. Dr. Florian Leese (Dean at the University of Duisburg-Essen, Germany, and Editor-in-Chief at the Metabarcoding and Metagenomics journal), where he talked about the promise, but also the challenges for DNA-based methods to empower biodiversity monitoring.
Amongst the key tasks here, he pointed out, are the alignment of DNA-based methods with the Global Biodiversity Framework; central push and funding for standards and guidance; publication of data in portals that adhere to the best data practices and rules; and the mobilisation of existing resources such as the meteorological ones.
He also made a reference to the Forum Paper “Introducing guidelines for publishing DNA-derived occurrence data through biodiversity data platforms” by R. Henrik Nilsson et al., where the international team provided a brief rationale and an overview of guidelines targeting the principles and approaches of exposing DNA-derived occurrence data in the context of broader biodiversity data. In the study, published in the Metabarcoding and Metagenomics journal in 2022, they also introduced a living version of these guidelines, which continues to encourage feedback and interaction as new techniques and best practices emerge.

A study from the Technical University Berlin suggests ‘sufficiency’ should be a more prominent strategy for protecting biodiversity.
Published in the open-access journal Nature Conservation, the paper analyses the intersection between biodiversity conservation and sufficiency strategies aimed at reducing consumption and resource use.
Study author Marianne Hachtmann notes that despite the established connection between excessive resource use by humans and biodiversity loss, there is limited explicit focus on how sufficiency strategies can support biodiversity preservation.
Reviewing literature from 2017 to 2021 and publications by nature conservation associations, the research identifies a notable gap in discussions linking sufficiency directly with biodiversity outcomes. Possible reasons for this may be the term’s political implications, lack of descriptiveness, and the use of other terms.
Research methodology
Furthermore, the lack of connection between sufficiency and biodiversity could be because they belong to different ‘scientific spheres’. Linking the two terms thus requires a reflective, interdisciplinary perspective.
The study proposes a detailed sufficiency typology to foster a systematic approach towards integrating the term in biodiversity conservation efforts.
“The sufficiency typology developed here allows for a systematic integration of sufficiency into biodiversity conservation and thus a joint consideration of social and nature conservation concerns.”
Marianne Hachtmann, Technical University Berlin
Policymakers, conservationists, and researchers are urged to prioritise sufficiency for the broader strategy for biodiversity conservation and sustainable living. The paper calls for further investigation into how sufficiency strategies can be crucial in conserving biodiversity and promoting sustainability.

Invasive species spread through human activities are one of the main causes of the ongoing biodiversity crisis.
Even on South Georgia, a remote island located in the very south of the Atlantic Ocean, exotic species are present. Many of which were inadvertently introduced by whalers and sealers in the 19th and early 20th century.
The invasive carabid ground beetle, Merizodus soledadinus, is present on sites that have been recently exposed by melting glaciers.
In a new study published in the open-access journal Neobiota and funded by Darwin Plus, researchers explored how living organisms colonise new ground provided by melting glaciers.
Like other cold regions of the world, South Georgia is losing its glaciers because of climate change, leaving behind large areas of newly uncovered bare ground.
Invasive annual meadow grass colonising ground only a few years after the glacier disappeared.
Researchers surveyed the foreland biodiversity of six glaciers, creating an inventory of the flora and fauna that colonise forelands at different stages of glacial retreat.
A survey site near a former whaling station (Grytviken).
They found that, just a few years after bare ground is exposed by a glacier melting, pioneer plants arrive, progressively covering more ground with time, followed by an increasing number of species.
Rocky terrain by Glacier Col.
Native and exotic plants, as well as invertebrates, take advantage of this opportunity. Surprisingly, two temperate plant species from the Northern Hemisphere, annual meadow grass and mouse-ear chickweed, colonise sites faster than any other species.
The team suggests their results indicate invasive species will likely spread on South Georgia as fast as glaciers are retreating. Whether this has or will have negative consequences on local species needs to be investigated to help protect this unique ecosystem.

A study spearheaded by researchers at the Helmholtz Centre for Environmental Research and Macquarie University has highlighted the important ecological role of traditional orchard meadows, calling for political and public support and incentives for farmers to protect these landscapes.
The paper, published in the open-access journal Nature Conservation, reviews the effects of management, habitat and landscape characteristics on the biodiversity of these areas in Central Europe.
Schematic figure illustrating the effects of management intensification on species richness. The graph illustrates the potential effect of management intensity (from high over intermediate to abandonment/rewilding) on species richness in orchard meadows.
Orchard meadows, characterised by the combination of cultivated grasslands and scattered fruit trees, exhibit high flora and fauna biodiversity. Despite their ecological value, these habitats have been in decline since the mid-19th century due their decreasing economic worth. They now face threats from land abandonment and intensification of agriculture.
The study emphasises the importance of moderate management intensity, connectivity to neighbouring habitats, and the preservation of structural diversity to maintain and enhance the conservation value of orchard meadows. The findings also advocate for a nuanced understanding of management impacts across taxonomic groups and points out the limitation of available studies on these habitats in Central Europe.
Currently loose in definition, the research team advocated for a clear definition of orchard meadows to create a common term in Europe, which would make their assessment and protection more straightforward. They suggest orchard meadows should be listed in the Habitats Directive of the Council of the European Union and farmers should get incentives for their maintenance. Finally, the research team calls for political and public support to prevent the loss and abandonment of these biodiverse landscapes.
“One way the public support the protection of these habitats is through consumer behaviour, specifically by purchasing local products from orchard meadows. However, it is crucial to subsidise these local products and prioritize them at local markets.
“As long as fruits from orchard meadows are treated as ‘by-products’ in the market, it will be challenging to convince people to buy local products. This change is necessary to close the economic gap between intensified fruit production and extensive orchard meadows.”

Males of the species have a yellow head and forebody and light blue spots on the back and they live in low elevation forests of the Southern Western Ghats.
You’ve probably seen nature depicted in art, but how often do you see an artwork hiding in nature?
When they saw the back of a lizard in the Southern Western Ghats, a group of scientists from the Thackeray Wildlife Foundation in India were reminded of Van Gogh’s The Starry Night. As soon as they figured out it was a new species, it was only apt to name it in honour of the famous painter.
“Cnemaspis vangoghi is named for Dutch painter Vincent Van Gogh (1853–1890) as the striking colouration of the new species is reminiscent of one of his most iconic paintings, The Starry Night,” explains Ishan Agarwal, who took part in the study to describe the new lizard. Males of the species have a yellow head and forebody and light blue spots on the back and they live among rocks and occasionally buildings and trees.

Together with his fellow researchers Akshay Khandekar and Tejas Thackeray, they found the new species during an expedition in April 2022 to the the Southern Western Ghats in Tamil Nadu, India. Now, they have published their findings in the peer-reviewed journal ZooKeys.
“Tamil Nadu is an exceptionally biodiverse state and we expect to name well over 50 new species of lizards by the time we are done [with our expeditions]!,” Ishan Agarwal says.

“I also had more than 500 tick bites during that summer trip, with the highest densities in the low-elevation, dry forests of Srivilliputhur, where the new species are found,” he adds.
Cnemaspis vangoghi is a small-sized gecko that can reach 3,4 cm in length. It was described as new to science together with another species of its genus, Cnemaspis sathuragiriensis, named for its type locality the Sathuragiri Hills.

“The two new species are distributed in low elevation (250–400 m asl.), deciduous forests of Srivilliputhur, and add to the five previously known endemic vertebrates from Srivilliputhur-Megamalai Tiger Reserve, Tamil Nadu, India,” Ishan Agarwal explains. They are diurnal and mainly active during the cool hours of the early morning and evening, found largely on rocks. So far, they have only been found in very restricted localities, “an interesting case of micro-endemism in low-elevation species,” he notes.

Two red-tailed coral snakes have been observed competing over a caecilian in the first documented wild case of kleptoparasitism within the family Elapidae.
Kleptoparasitism, or food theft, is a well-documented behaviour in many animal species but is seldom reported among snakes in natural habitats.

The observation, detailed in a recent study published in the open-access journal Herpetozoa by Henrik Bringsøe and Niels Poul Dreyer, showcases the two Micrurus mipartitus snakes engaging in a tug of war over the limbless amphibian.
Elapid snakes are venomous and among the deadliest serpents in the world. There are more than 400 species comprising a very diverse group of snakes such as mambas, cobras, kraits, taipans, tiger snakes, death adders, sea snakes and coral snakes.

The battle occurred in the dense rainforests of Valle del Cauca, western Colombia. Surprisingly, in the tussle, one snake also bit the body of the other. However, the researchers suggest this was likely accidental.
After 17 minutes of observation, the losing coral snake released its bite-hold on the caecilian. The winner then moved away from the losing snake which did not follow.

The study suggests that while such behaviours may be more common in captivity due to controlled environments, their occurrence in nature has been largely underreported, likely due to the elusive nature of these reptiles and the challenges of observing them in their natural habitats.
“Snakes in captivity do that often when only one prey is offered in a terrarium with two or more snakes. But it is rather surprising that it has not been observed more frequently in the wild.”
Henrik Bringsøe, lead author.
This case sheds light on the coral snake interactions with prey species. Caecilians, such as the one in this study, have shown remarkable adaptations such as toxin resistance and increased mucus production.
Henrik Bringsøe previously recorded snake feeding behaviour that was entirely new to science. Check out his guest blog post on the snakes that disembowel and feed on the organs of living toads.
