Efficiency of insect biodiversity monitoring via Malaise trap samples and DNA barcoding

The massive decline of over 75% insect biomass reported from Germany between 1989 and 2013 by expert citizen scientists proves the urgent need for new methods and standards for fast and wide-scale biodiversity assessments. If we cannot understand species composition, as well as their diversity patterns and reasons behind them, we will fail not only to predict changes, but also to take timely and adequate measures before species go extinct.

An international team of scientists belonging to the largest and connected DNA barcoding initiatives (iBOL, GBOL, BFB), evaluated the use of DNA barcode analysis applied to large samples collected with Malaise traps as a method to rapidly assess the arthropod fauna at two sites in Germany between May and September.

One Malaise trap (tent-like structure designed to catch flying insects by attracting them to its walls and then funneling them into a collecting bottle) was set in Germany’s largest terrestrial protected natural reserve Nationalpark Bayerischer Wald in Bavaria. Located in southeast Germany, from a habitat perspective, the park is basically a natural forest. The second trap was set up in western Germany adjacent to the Middle River Rhine Valley, located some 485 kilometers away from the first location. Here, the vegetation is eradicated annually due to St. Martin’s fires, which occur every November. Their findings are published in the open access Biodiversity Data Journal.

DNA barcoding enables the identification of a collected specimen by comparing its BIN (Barcode Index Number) against the BOLD database. In contrast to evaluation using traditional morphological approaches, this method takes significantly less experience, time and effort, so that science can easily save up on decades of professional work.

However, having analyzed DNA barcodes for 37,274 specimens equal to 5,301 different BINs (i.e., species hypotheses), the entomologists managed to assign unambiguous species names to 35% of the BINs, which pointed to the biggest problem with DNA barcoding for large-scale insect inventories today, namely insufficient coverage of DNA barcodes for Diptera (flies and gnats) and Hymenoptera (bees and wasps) and allied groups. As the coverage of the reference database for butterflies and beetles is good, the authors showcase how efficient the workflow for the semi-automated identification of large sample sizes to species and genus level could be.

In conclusion, the scientists note that DNA barcoding approaches applied to large-scale samplings collected with Malaise traps could help in providing crucial knowledge of the insect biodiversity and its dynamics. They also invite their fellow entomologists to take part and help filling the gaps in the reference library. The authors also welcome taxonomic experts to make use of the unidentified specimens they collected in the study, but also point out that taxonomic decisions based on BIN membership need to be made within a comparative context, “ideally including morphological data and also additional, independent genetic markers”. Otherwise, the grounds for the decision have to be clearly indicated.

The study is conducted as part of the collaborative Global Malaise Trap Program (GMTP), which involves more than 30 international partners. The aim is to provide an overview of arthropod diversity by coupling the large-scale deployment of Malaise traps with the use of specimen-based DNA barcoding to assess species diversity.

Sequence analyses were partially defrayed by funding from the government of Canada through Genome Canada and the Ontario Genomics Institute in support of the International Barcode of Life project. The German Barcode of Life project (GBOL) is generously supported by a grant from the German Federal Ministry of Education and Research (FKZ 01LI1101 and 01LI1501) and the Barcoding Fauna Bavarica project (BFB) was supported by a 10-year grant from the Bavarian Ministry of Education, Culture, Research and Art.

People can simultaneously give a hand to endangered apes and stay at safe distance

Primates claim the highest proportion of endangered species among all mammals, according to the IUCN Red List. Yet, the substantial conservation interference from humans, which is already in place, could itself lead to even greater losses.

Plenty of studies have proven that while researchers and ecotourists raise vital for ape conservation knowledge and funds, it is actually human presence that compromises primates’ well-being due to extremely similar genetics and, thereby, easily transmittable diseases, ranging from common cold to human tuberculosis and Ebola fever.

In a paper published in the open access journal BioRisk, Rhiannon Schultz, Miami University, seeks the golden mean between giving ape species a hand and keeping safe distance. To showcase the impact human have on primates, the scientist makes example of the Mountain gorilla, an endangered species living in the montane forests of the Democratic Republic of Congo, Uganda and Rwanda.

Simply being in close proximity to primates, humans can easily transmit a wide range of diseases to the animals, including intestinal parasites, hepatitis, tuberculosis, Typhoid fever, Cholera, and Ebola fever. The transmission can occur as easily as having the two species breathing the same air, or the people leaving a banana peel behind.

Furthermore, threats to the gorilla species are also posed by the humans destroying the primates’ habitats. The result is overlapping populations, where a disease is much easier to transmit among the small gorilla populations. For example, normally an ill individual would be put under a ‘natural quarantine’, which is impossible when the habitat has already been reduced.

In the meantime, banning people, both tourists and scientists, from gorilla habitat is not an option, since knowledge about the populations’ dynamics is essential for the conservation of all primate species. On the other hand, ecotourism is what raises a great part of the resources need for conservation work. Income from gorilla trekking is enough to support the Ugandan Wildlife Authority, while also contributing a significant part to the country’s national budget.

The key, Rhiannon Schultz concludes, is to, firstly, promote understanding of the risk for interspecies disease transmission as a conservation threat, and then, improve on current protocols and regulations.

“It may be difficult to ask tourists to wear masks while visiting animals in the wild, and it may be expensive to maintain a veterinary program for wild populations and to improve healthcare systems for local people, but making these improvements could be the key to preventing disease transmission to not only Mountain gorillas but also to other apes,” sums up the scientist.

Claims that declines of pollinator species richness are slowing down in Europe revisited

Having conducted a thorough interpretation of the results of a recent study that inferred decrease in the biodiversity loss among pollinators across Europe, Dr Tom J. M. Van Dooren reveals that this conclusion cannot in fact be drawn. It is only supported for the bee fauna in the Netherlands. His study is published in the open access journal Nature Conservation.

Changes in pollinator abundances and diversity are of major concern. Pollinator diversity is quantified by their species richness: the number of species from a specific taxonomic group of pollinating animals present at a given time in a given area. A recent study, adopted in the recent UN IPBES Pollination Report draft summary, inferred that pollinator species richnesses are decreasing more slowly in recent decades in several taxonomic groups and European countries.

However, Dr Tom J. M. Van Dooren, affiliated with both Naturalis Biodiversity Center, the Netherlands, and the Institute of Ecology and Environmental Sciences of Paris, France, has now published his own study to show in detail the inaccuracies that the earlier conclusion has been based on.

Among other points, the scientist notes that the earlier study contained no explicit statistical comparisons between species richness changes in different periods. The earlier study also treated richness changes at country level and small spatial resolution as equivalent, while they probably represent different processes.

“Plants in Great Britain at the smallest spatial scales suggest a reduced rate of changes, but the results for larger spatial scales are not significant,” he illustrates. “The same holds for butterflies in the Netherlands.”

Dr Tom J. M. Van Dooren only finds support in the results of the earlier publication for a decelerating decline in bumblebees and other wild bees in the Netherlands. “This is in fact one taxon, the bees Anthophila, in a single country, the Netherlands”, he notes.

“The lack of robustness points again to the possibility that results found in the data can be due to changes in the shapes of species accumulation curves,” Dr Tom J. M. Van Dooren summarises. “Therefore the status of the statement on decelerating declines in the Pollination Report should be adjusted accordingly.”

Online sales of threatened cacti point to the Internet as an open door for illegal trade

International trade of wildlife on the Internet is highly unregulated and has become a threat for species survival. Threatened cacti are available on websites and shipped across countries without any legal documents to certify their trade is not a menace to population viability in the wild. Is this ignorance or unwillingness to comply with regulations? Study published in the open access journal Nature Conservation reports on the activity and discusses assessment methods and solutions.

In present days, trade of species is possible without any real human interaction, and distance is no longer an obstacle. Although conventional trade routes are maintained through shipping of goods, the widespread use and the unregulated nature of the Internet make e-commerce a great concern to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

This convention regulates international trade through issuing and control of permits, which aim to guarantee that the trade of individuals is not a threat to the survival of a species in the wild. Due to the magnitude of the international trade, the entire cacti family is under CITES.

In their study, scientists Vania Olmos-Lau and Dr María C. Mandujano, both affiliated with the Universidad Nacional Autónoma de México (UNAM), México, present a quick and easy method to assess the online availability of a highly collectible Mexican threatened cactus, commonly known as disc cactus. The method can be readily used to assess other species.

Because of its threatened status, no commercial trade of wild specimens is allowed and a collection permit is needed for harvest of seeds and individuals. Plants and seeds were found available in major online markets like eBay and Amazon, and were also offered via online stores based in the USA, France, Germany, Australia, the Czech Republic, the UK, and others. Researchers point out that the Asian market was underestimated due to language constraints.

Only a minority of these online stores openly stated that they would provide CITES documentation, or that plants were obtained from nurseries that grew cacti themselves. Results also indicate that the country home to this species, Mexico, plays no important role in the legal international trade of the species.

“This method is easily transferable to estimate the illegal market for any species and offers an understanding of the real magnitude and main targets of this new form of threat,” note the authors. “Compliance or other regulation mechanisms are needed in order to promote species conservation.”

For major online stores like eBay, Mercado Libre and Amazon, the researchers propose a policy based on filtering the publications which contain the name of CITES species.

For example, there could be downloadable forms for the sellers to sign and prove that they assume responsibility for the legal origin of the product. Also, a pop up window could let buyers know what a CITES species is and what its acquisition involves. After all, most times the lack of compliance with regulations for wildlife trade is a matter of ignorance rather than disobedience.

“We need to open our eyes to the demand for wildlife and how it can be satisfied through fair trade schemes that benefit local landowners,” point out the researchers.

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.
