Thousands of illegally traded wild animals at risk due to gaps in data

The fate of over 64,000 live wild animals officially reported to have been confiscated by CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) enforcement agencies between 2010 and 2014 remains untraceable, according to a new report released by the University of Oxford Wildlife Conservation Research Unit (WildCRU) and World Animal Protection.

In their publication in the open access journal Nature Conservation, the researchers document merely one in three partnering to CITES countries providing any data on seizures, and also highlight the importance of having this changed.

Although the reported number of confiscated animals is staggering, the researchers warn that these are likely to be only a fraction of the actual seizures. The study found two out of three countries did not report any live wildlife seizures, despite poaching of endangered species and supplying the illicit global wildlife trade being estimated to be worth between $8-10 billion per year.

The figures have prompted calls for better reporting of seizures and what happens to confiscated live wild animals.

The ultimate fate of seized live wild animals is unknown, the researchers found. Once animals have been confiscated, national authorities must decide whether to: keep them in captivity, return them to the wild or euthanize them. CITES provides guidelines to aid this decision-making based on the conservation status and welfare needs of the animals.

However, information about the fate of these wild animals is not a formal CITES requirement and as a result, there are no official numbers on just how many were euthanized, placed in captivity or returned to the wild.

Researchers are concerned this lack of data is placing the well-being and survival of seized wildlife at risk – many wild animals could be re-entering the wildlife trafficking industry as they simply can’t be accounted for.

University of Oxford‘s Professor David Macdonald, senior researcher for the study, said:

“We fear this staggering number is just the tip of the iceberg. Only a relatively small proportion of wild animals involved with illegal trade are thought to be intercepted by enforcement agencies – confiscation records were completely missing for 70% of countries Party to CITES. Given the rapidly growing global trends in illegal wildlife trade activity, it is highly unlikely that no live wildlife seizures were made on their borders.

“The records that were provided show that around 20% of all live wild animals reported as seized are currently considered to be threatened by extinction. We strongly recommend that the CITES trade database should include information on the fate of all live wild animal seizures, so we know what happens to these animals, and we can reduce the risk of them re-entering the illegal wildlife trade.”

World Animal Protection’s Dr Neil D’Cruze, lead researcher for the study, said:

“The illegal wildlife trade is a big, complex and dirty business. National authorities play a key role, facing some tough choices when they seize animals – whether they release them in the wild, place them in care in captivity or euthanize them.

“Improved data recording is critical to knowing what happens to each animal, and can help in looking at the challenges and issues enforcement agencies face in managing animals after seizure. Without this transparency, there’s a real possibility that endangered species may be put back into the hands of the same criminals whom they were taken from. We need to be able to account for these wild animals.

“If we’re really serious about protecting wildlife, action needs to be taken at all levels. It’s unfathomable that 70% of countries recorded no seizures when we know a global, multi-billion wildlife trafficking industry is flourishing.”

The findings and recommendations of this research were presented at the 17th meeting of the Conference of the Parties (CoP) in Johannesburg, South Africa on 27 September 2016 during a side event focused on the confiscation of live wild animals organised by the Species Survival Network (SSN).

Species conservation profile of a critically endangered endemic for the Azores spider

Subject to continuing population decline due to a number of factors, an exclusively cave-dwelling (troglobitic) spider endemic to the Azores is considered as Critically Endangered according to the IUCN Red List criteria.

To provide a fast output, potentially benefiting the arachnid’s survival, scientists from the IUCN – Spider and Scorpion Specialist Group and the Azorean Biodiversity Group (cE3c) at University of Azores, where the main objective is to perform research that addresses societal challenges in ecology, evolution and the environment, also known as the three E’s from the centre’s name abbreviation, teamed up with colleagues from University of Barcelona, Spain, and the Finnish Museum of Natural History.

Together, they make use of a specialised novel publication type feature, called Species Conservation Profile, created by the open access journal Biodiversity Data Journal, to provide scholarly credit and citation for the IUCN Red List species page, as well as pinpoint the population trends and the reasons behind them.

The studied spider species (scientifically called Turinyphia cavernicola) is a pale creature with long legs, large eyes and a total size of merely 2 mm in length. These spiders never leave their underground habitats, which are strictly humid lava tubes and volcanic pits. There they build sheet webs in small holes and crevices on the walls of the caves.

Not only is the species restricted to a single island within the Azorean archipelago (Portugal), but it is only found in three caves. Furthermore, out of the three, only one of them is home to a sustainable large population. These caves are under severe threat due to pasture intensification, road construction and tourist activities.

Although there is not much information about the species distribution through the years, with the spider having been discovered as recently as in 2008, the authors make the assumption that originally there have been significantly greater populations. Not only have they studied thoroughly another fifteen caves located on the island without finding any individuals, but they have identified increasing anthropogenic impact on the habitat.

“The species original distribution was potentially very large compared with the current,” the scientists explain. “Relatively intensive searches in and around the current caves where the species occurs have failed to find additional subpopulations.”

“The trend of decline is based on the assumption that this species can occur in all these caves and that the absence is due to anthropogenic disturbance on caves during the last 50 years,” they note.

Orchid or Demon: Flower of a new species of orchid looks like a devil’s head

A lone and unique population of about 30 reddish to dark violet-maroon orchids grows on the small patch of land between the borders of two Colombian departments. However, its extremely small habitat is far from the only striking thing about the new species.

A closer look at its flowers’ heart reveals what appears to be a devil’s head. Named after its demonic patterns, the new orchid species, Telipogon diabolicus, is described in the open access journal PhytoKeys.

Discovered by Dr Marta Kolanowska and Prof Dariusz Szlachetko, both affiliated with University of Gdansk, Poland, together with Dr Ramiro Medina Trejo, Colombia, the new orchid grows a stem measuring between 5.5 – 9 cm in height.

With its only known habitat restricted to a single population spread across a dwarf montane forest at the border between departments Putumayo and Nariño, southern Colombia, the devilish orchid is assigned as a Critically Endangered species in the IUCN Red List.

Although the curious orchid could be mistakenly taken for a few other species, there are still some easy to see physical traits that make the flower stand out. Apart from the demon’s head hidden at the heart of its colours, the petals themselves are characteristically clawed. This feature has not been found in any other Colombian species of the genus.

“In the most recent catalogue of Colombian plants almost 3600 orchid species representing nearly 250 genera are included,” remind the authors. “However, there is no doubt that hundreds of species occurring in this country remain undiscovered. Only in 2015 over 20 novelties were published based on material collected in Colombia.”

Bee populations expanded during global warming after the last Ice Age

The Australian small carpenter bee populations appear to have dramatically flourished in the period of global warming following the last Ice Age some 18,000 years ago.

The bee species is found in sub-tropical, coastal and desert areas from the north-east to the south of Australia. Researchers Rebecca Dew and Michael Schwarz from the Flinders University of South Australia teamed up with Sandra Rehan, the University of New Hampshire, USA, to model its past responses to climate change with the help of DNA sequences. Their findings are published in the open access Journal of Hymenoptera Research.

“You see a rapid increase in population size from about 18,000 years ago, just as the climate began warming up after the last Ice Age,” says lead author Rebecca Dew. “This matches the findings from two previous studies on bees from North America and Fiji.”

“It is really interesting that you see very similar patterns in bees around the world,” adds Rebecca. “Different climate, different environment, but the bees have responded in the same way at around the same time.”

In the face of future global warming these finding could be a good sign for some of our bees.

However, the news may not all be positive. There are other studies showing that some rare and ancient tropical bees require cool climate and, as a result, are already restricted to the highest mountain peaks of Fiji. For these species, climate warming could spell their eventual extinction.

“We now know that climate change impacts bees in major ways,” says Rebecca, “but the challenge will be to predict how those impacts play out. They are likely to be both positive and negative, and we need to know how this mix will unfold.”

Bees are major pollinators and are critical for many plants, ecosystems, and agricultural crops.

From a bulletin to a modern open access journal: Italian Botanist in Pensoft’s portfolio

Established in the distant 1888, the Italian Botanical Society has gone a long way towards publishing its achievements and research. Originated as a bulletin within an Italian journal, they have been growing ever since to now form a new international journal in its own right. Covering both Italian and international research in botany and mycology, the online open access journal Italian Botanist, published by Pensoft, is now officially launched via its first papers.

Although what was later to become Italian Botanist, published its first issue as an independent journal, called Informatore Botanico Italiano in 1969, the publications were still rather bulletin-style. It consisted of a mixture of administrative and scientific proceedings of the Society, the yearbook of the members, as well as scientific notes.

Nevertheless, such a major transition has been set to change everything fundamentally. Establishing its name, the journal started picking up, so that it was not long before the scientific contributions were prevailing. Impressively, for the Society’s centenary the journal published a celebratory 331-page contribution.

Gradually, its scope was expanded to cover several scientific fields. It hosted several themed columns, including cytotaxonomic contributions on the Italian flora, relevant new floristic records for Italy, conservational issues concerning the Italian flora and mycology.

However, the Directive Council of the Italian Botanical Society has not seemed to be ready to give up on their journal’s evolution. Last year, the botanists decided that they need to transform the journal to an an online, open access journal written in English and called Italian Botanist, in order to boost the scientific value and international visibility of Informatore Botanico Italiano.

Under the name Italian Botanist, the journal has now joined Pensoft’s portfolio of peer-reviewed open access journals, all of which take advantage of the advanced technologies and innovations developed by the publisher.

The new journal’s scope ranges from molecular to ecosystem botany and mycology. The geographical coverage of Italian Botanist is specially focused on the Italian territory, but studies from other areas are also welcome.

Staying faithful to its spirit and philosophy, it keeps its column-format, with each issue to contain five columns, namely Chromosome numbers for the Italian flora, Global and Regional IUCN Red List Assessments, Notulae to the Italian flora of algae, briophytes, fungi and lichens, Notulae to the Italian native vascular flora and Notulae to the Italian alien vascular flora.

“Our hope is that this renewed version of the journal will serve the Italian – and foreign – botanical community more efficiently and provide readers worldwide with an easier access to knowledge concerning the Italian flora,” says Italian Botanist‘s Editor-in-Chief Lorenzo Peruzzi.

Flightless survivors: Incredible invertebrate diversity in Los Angeles metropolitan area

Urban wildlife is surprisingly understudied. We tend to know more about animals in exotic places than about those that live in our cities.

This is why researchers Emile Fiesler, president of Bioveyda Biological Inventories, Surveys, and Biodiversity Assessments, USA, and Tracy Drake, manager of the Madrona Marsh Preserve, looked into the fauna of the Madrona Marsh Preserve, California, a small nature preserve in one of the world’s largest metropolitan areas.

Consequently, they published the astonishing number of 689 species of invertebrates, which have managed to survive decades of farming and oil exploration, followed by development pressures, in the open access Biodiversity Data Journal. The study was minimally invasive as the live animals have been recorded with macro-photography.

Even though it is the insects that first developed the ability to fly, long before the dinosaurs became birds, the latter have always received the most of our attention. This major evolutionary breakthrough, which has occurred more than once in the past, is also a reason why insects are currently the most diverse animals on earth in terms of number of species.

“Insects and other invertebrates have filled all ecological niches and all corners of our planet,” explain the authors. “No surprise that these small creatures conquered our cities and invaded our homes as well.”

Most of the urban dwellers, however, have been introduced – accidentally or deliberately – by humans.

“The remainder – native ‘wild’ species – are able to survive in the city mainly due to their adaptivity,” they point out. “It is therefore surprising to find a number of flightless species in a small area surrounded by urbanization.”

The Madrona Marsh Preserve is located in Torrance, which is part of the Los Angeles metropolitan area. The greater Los Angeles Metropolitan area is one of the world’s largest, with a human population of more than 17 million.

The Madrona Marsh Preserve, boasting seasonal wetlands, is well known as a birdwatchers’ paradise. Besides birds, its other vertebrates (mammals, reptiles, amphibians, and fishes), as well as its flowering plants, are relatively well known. The invertebrate fauna of the Preserve, on the other hand, aside from butterflies and dragonflies, was virtually unknown.

Interestingly, night surveys revealed the presence of a ‘second shift’ diversity, or creatures seemingly complementary to those active during the day.

Among the long-time survivors are wingless camel crickets as well as velvet ants, which are wasps whose flightless females look like furry ants. Another curiosity that intrigued the researchers is an obscure flightless female bradynobaenid wasp.

The researchers were especially surprised by their encounter with a large Solifugid [image 3] – also known as Camel Spider or Wind Scorpion. Solifugids are little-known arachnids that are neither spiders, nor scorpions, and can grow up to 15 cm (6 in). Their order’s name Solifugae translates from Latin as “those that flee from the sun”.

All in all, the biodiversity study resulted in 689 species without a backbone, belonging to 13 classes, 39 orders, and 222 families, found on this island surrounded by urbanization.

“Not unlike the moas and dodos, these ‘island’ inhabitants stayed grounded through the ages,” acknowledge the researchers.

Undergraduate student takes to Twitter to expose illegal release of alien fish in Japan

Posing a significant threat to the native biodiversity in Japan, specifically that of threatened aquatic insects, some alien fishes, such as the bluegill, have become the reason for strict prohibitions. All activities potentially capable of introducing the species into the wild are currently punishable by either a fine of up to 3 million yen for a person (100 million yen for corporations), or a prison sentence of up to 3 years.

Recently, ten years after the law has been adopted, illegal release of bluegill fish has been reported for the first time with the help of a post on Twitter from Akinori Teramura, undergraduate student at the Tokyo University of Marine Science and Technology and second author of the present study. The case is reported and discussed by him and two scientists, affiliated with Kanagawa Prefectural Museum of Natural History, Japan, in the open-access journal ZooKeys.

In June 2015, Akinori Teramura tweeted two photographs of the invasive bluegill fish, both adults and juveniles, along with two young goldfish, which do not belong to the local fauna, either. In his post he identified the species and shared his surprise at the irresponsibility of the people who had released the fish. When lead author Dr Yusuke Miyazaki saw the tweet, he signalled his colleagues with the idea to publish the information as a scientific report.

The student found them in an outdoor public pool in Yokohama city, Japan, while it was being cleaned before being opened ahead of the summer. Usually, these facilities are closed to the public during the colder seasons and it is then when native aquatic insect species, such as dragonflies and diving beetles, find spawning and nursery habitats in them. Curiously enough, though, the pool had been isolated from natural waters since its construction.

Therefore, the researchers conclude that the alien fishes have most likely been released from an aquarium from a local shop or an aquarist who no longer wanted them. However, the authors note that according to the law, keeping bluegill fish in a home aquarium is illegal as well.

“Our report demonstrates an example of web data mining in the discipline of Citizen Science,” say the authors. “Web data mining has been rapidly developing over recent years, and its potential continues to expand.”

“Community awareness of this issue needs to be improved, and widespread reporting of cases such as this one will help,” they conclude.

Conservation hopes up for the endangered banana frog restricted to Southwest Ethiopia

As the natural forest cover in Ethiopia is already less than 3% of what it once has been, the banana frog species, dwelling exclusively in the remnants of the country’s southwestern forests in only two populations, is exposed to a great risk of extinction.

Through their survey, a research team, led by Matthias De Beenhouwer, Biodiversity Inventory for Nature Conservation (BINCO), Belgium, have now extended the species’ range, thus making the first steps to saving the charming frogs. The study is published in the open-access journal ZooKeys.

Although Ethiopia is known for its high number of both animal and plant species that do not live anywhere else in the world, there is a concerning lack of conservation activities to preserve the local biodiversity. Moreover, while as much as 41% of the amphibians ever recorded in the country are exclusive for its fauna, there have been only few researches. Without such, pointing the hotspots in greatest need of protection and restoration, as well as taking adequate measures subsequently, is impossible.

Concerned about the endangered status of the banana frog, and supported with a Rufford grant, Matthias and his team spent ten evenings, or 111 hours, in August 2014, seeking and collecting as many frogs as possible from seven different locations. When they determined the species status of the found individuals, it turned out that they have managed to discover several new populations of banana frogs from unexpected localities.

As a result of their survey, the geographical range of the Ethiopian banana frog has been expanded by roughly 40 km towards the North and 70 km to the East. Its altitudinal distribution already reaches a maximum of 2030 metres above sea level, compared to the previously known maximum of 1800 m.

Banana frogs being identified from outside forest habitats is also a good news for the species’ preservation since it shows that not only are the frogs more tolerable against forest degradation than expected, but that also there could be even more populations.

“Although Southwest Ethiopia is known to harbour the last large tracts of natural forest, forest cover has declined dramatically to less than 3% nationwide,” point out the researchers. “Therefore, accurate information on species conservation and distribution is an essential first step to facilitate the delivery of conservation updates, recognize biodiversity hotspots and encourage habitat protection and restoration.”

New caddisfly species discovered in the Balkan biodiversity hotspot of Kosovo

The Republic of Kosovo turns out to be a unique European biodiversity hotspot after a second new species of aquatic insect has been described from the Balkan country. The new caddisfly was discovered by Prof. Halil Ibrahimi from the University of Prishtina, Kosovo, and international research team. They have their finding published in the open-access journal ZooKeys.

The new caddisfly species was found during a field trip, undertaken by the scientists in Sharr National Park in Kosovo. The aquatic insect belongs to the highly diverse genusDrusus, which, unfortunately, is under threat of extinction because of the ongoing pollution activities and mismanagement of freshwater ecosystems.

Called Drusus sharrensis, the new caddisfly has been named after the mountains where it was found. Thus, it is yet another example for a species, either animal or plant, bearing the same combination of names, and highlighting this range of mountains as a highly rich in rare and endemic species.

“Even though just discovered, the species may be already threatened by illegal logging, water extraction from springs, expansion of touristic activities and several other anthropogenic factors,” points out the author, “such as limestone and rock quarries operating in the Sharr Mountains in the vicinity of aquatic ecosystems potentially causing severe siltation.”

“Additionally, recent development of a winter tourism facility at Brezovice, close to the type locality of the new species, may enhance local degradation of terrestrial and, particularly, aquatic ecosystems in the Sharr Mountains,” he further explains. “The Brezovica Touristic Centre Development Project was designed by the Government of the Republic of Kosovo with support from the European Union to promote the touristic appeal and thus, economic importance of the area. This project will impact a total area of roughly 3,700 ha.”

This is the second aquatic insect species discovered from Kosovo for the last twelve months and probably more are to be expected in this highly under-investigated area of the European continent.

‘Hidden fish’ genus described for 2 new weakly electric mormyrid species from Gabon

A new weakly electric mormyrid fish genus of two new species has been described from only three specimens collected over a period of 13 years in the rivers of the Central African country of Gabon. The genus has been named Cryptomyrus, meaning ‘hidden fish’ in Greek, and is the first new genus to be described within the family Mormyridae since 1977.

The study, authored by Dr. John Sullivan and Prof. Carl Hopkins of Cornell University, Ithaca, New York, and Sebastien Lavoue of the Institute of Oceanography at the National Taiwan University in Taipei, Taiwan, is published in the open-access journal ZooKeys.

“It’s odd we have only three specimens, given how much fish collection effort there’s been in Gabon over the past years,” says lead author Dr. John Sullivan. “Not having more made the descriptions difficult, but it was important to bring this discovery to light without further delay.” Sullivan added that he does not know if these fish are rare throughout their range or if specialists simply have not sampled localities or habitats where they are common, yet. “It shows that we still have a very incomplete picture of fish diversity in Gabon,” says Dr. Sullivan.

The last of the three specimens was found on an expedition to Gabon’s Ogooue River in September 2014, jointly sponsored by CENAREST and The Nature Conservancy. It was after nightfall on the Ogooue, beside Doume Falls, when Sullivan and the other team members caught the one odd fish in a plastic fish trap baited with earthworms. Reflecting its river of origin, the species now bares the name Cryptomyrus ogoouensis, while the second – Cryptomyrus ona, is named after Gabonese environmental activist Marc Ona Essangui.

Puzzled over the identity of the fish, back home at the Cornell University Museum of Vertebrates Dr. Sullivan remembered two somewhat similar specimens collected in Gabon and sent to him for identification by his colleagues Sebastien Lavoue and Yves Fermon, 11 years apart. “This is why we need natural history collections,” said Dr. Sullivan, “to keep these specimens and their DNA samples in good condition, because it can take years or even decades to connect the dots.”

Analyses of the DNA from the three specimens conducted at Cornell University showed they were close relatives and did not belong within any recognized genus. “That left us no choice but to describe them as a new genus, and Cryptomyrus, which means “hidden fish,” seemed an appropriate name given how hard they are to find,” said Dr. Sullivan.

Over 200 species of mormyrid fish live in fresh waters across Africa where they orient to their environment and communicate using electric pulses, too weak to be felt by humans, in combination with highly sensitive electroreceptor cells embedded in their skin.

The Nature Conservancy, a global conservation organization that works in more than 35 countries around the world, funded the 2014 expedition of the Ogooue. “We were thrilled to have contributed to this discovery,” said Marie-Claire Paiz, Gabon Program Director for The Nature Conservancy. “Our goal is to help Gabon acquire better baseline knowledge about the state of their fish and rivers which will enable them make science-guided choices about where and how to use their resources wisely for both people and nature.”

“The Nature Conservancy deserves a lot of credit,” commented Sullivan. “It’s a great example of how a conservation organization can promote the discovery of biodiversity by partnering with taxonomists and natural history museums.”
