Picos de Europa National Park has given its name to a new species of perennial bromegrass, discovered in Spain. Bromus picoeuropeanus belongs to a rather underrepresented on the Iberian Peninsula perennial group within the grass genus Bromus, with the new species being just the fourth of all recognised wild species living in the Iberian territory.
Having worked on the systematics of Bromus for a long time, scientists Dr Carmen Acedo and Dr Félix Llamas, members of the Taxonomy and Biodiversity Conservation research group TaCobi of the Spanish University of León, were surprised to collect what seemed a so-far-unrecognised species of the rare for Iberia perennial group. The unlikely discovery of the new species was described and published in the open access journal PhytoKeys, while its type specimen is preserved on Herbarium LEB.
This is the preferred habitat of Bromus picoeuropeanus in stony and unstable soils, c. 1900 m elevation.
Failing to understand how it was possible that the new species has never been found in the over-studied territory of Picos de Europa National Park, the two researchers traveled back to the classic locality to confirm its presence and study the habitat. Interestingly, while the new species is located in a typical for the National Park habitat, only a single perennial Bromus species was previously known from the area.
Eventually, having spent more time studying and collecting samples of different taxa in the Park, the authors discovered several more individuals of the new species dwelling in stony areas at an altitude of 1600 – 2200m. While herbarium collections from the National Park revealed that samples were also collected some years ago by another botanist, the scarcity of populations of the new species is still striking given the abundance of other brome-grass species.
Unlike its sister species, the Picoeuropean brome-grass is a small rhizomatous herb up to 70 cm high. Another easy-to-recognize difference is its well-developed subterraneous vegetative organ, forming a long rootstalk called rhizome, which is an easy distinctive trait.
“Given the inaccessibility of the areas, the mountainous topography and the few grass-species-loving botanists, this species was ignored until now. Probably the genus Bromus has undergone some local speciation on this isolated place, but exactly how this occurred requires further investigation,” explain the authors noting the isolation of the new species from its relatives in the area.
Gaming and virtual reality could bridge the gap between urban societies and nature, thereby paving the way to insect conservation by the means of education and participation. This is what an interdisciplinary team at Florida International University strive to achieve by developing a virtual reality game (desktop version also available) dedicated to insect and plant species. Focused on imperiled butterflies, their innovative idea: Butterfly World 1.0, is described in the open-access journal Rethinking Ecology.

Gaming and virtual reality (VR) could bridge the gap between urban societies and nature, thereby paving the way to insect conservation by the means of education, curiosity and life-like participation.
This is what Florida International University‘s team of computer scientist Alban Delamarre and biologist Dr Jaeson Clayborn strive to achieve by developing a VR game (desktop version also available) dedicated to insect and plant species. Focused on imperiled butterflies, their innovative idea: Butterfly World 1.0, is described in the open-access journal Rethinking Ecology.

Butterfly World 1.0 is an adventure game designed to engage its users in simulated exploration and education. Set in the subtropical dry forest of the Florida Keys (an archipelago situated off the southern coast of Florida, USA), Butterfly World draws the players into an immersive virtual environment where they learn about relationships between butterflies, plants, and invasive species. While exploring the set, they interact with and learn about the federally endangered Schaus’ swallowtail butterfly, the invasive graceful twig ant, native and exotic plants, and several other butterflies inhabiting the dry forest ecosystem. Other nature-related VR experiences, including conservation awareness and educational programs, rely on passive observations with minimal direct interactions between participants and the virtual environment.
According to the authors, virtual reality and serious gaming are “the new frontiers in environmental education” and “present a unique opportunity to interact with and learn about different species and ecosystems”.

The major advantage is that this type of interactive, computer-generated experience allows for people to observe phenomena otherwise impossible or difficult to witness, such as forest succession over long periods of time, rare butterflies in tropical dry forests, or the effects of invasive species against native wildlife.
“Imagine if, instead of opening a textbook, students could open their eyes to a virtual world. We live in a time where experiential learning and stories about different species matter, because how we feel about and connect with these species will determine their continued existence in the present and future. While technology cannot replace actual exposure to the environment, it can provide similar, near-realistic experiences when appropriately implemented,” say the scientists.
In conclusion, Delamarre and Clayborn note that the purpose of Butterfly World is to build knowledge, reawaken latent curiosity, and cultivate empathy for insect and ecosystem conservation.

Known to science since 1857, a common species of true frog (a “true frog” is one assigned to the family Ranidae), found from north-eastern Honduras, through Nicaragua and Costa Rica to central Panama, turns out to have been keeping its “multiple identities” a secret all along.
According to British and Costa Rican herpetologists, who recently used DNA barcoding to study the species in question, what we currently call Warszewitsch’s frog is in fact a group of “cryptic” species. The study, conducted in the Área de Conservación Guanacaste (ACG), Costa Rica, by James Cryer, Dr Robert Puschendorf, Dr Felicity Wynne from the University of Plymouth, and Dr Stephen Price, UCL, is published in the open-access journal ZooKeys.
In their paper, the authors suggest that the well-known Central American frog species, commonly known as the Warszewitsch’s frog, may in fact consist of multiple different “cryptic” species. This phenomenon is well documented among tropical amphibian fauna, where high levels of genetic variation within populations of a single species surpass levels found between different, classified species.

By utilizing a technique known as DNA barcoding, which compares short snippets of DNA sequences between individuals sampled, the scientists analysed specimens from three different geographic areas within Costa Rica and Panama. In this case, the researchers used sequences derived from mitochondria, the energy-producing “power houses” found in animal cells. Their results indicated there was enough genetic variation to suggest cryptic species are indeed present.
The team chose this particular species because cryptic species were previously identified at two Panamanian sites. Now, the samples from Costa Rica broaden the study area, suggesting that there could be multiple species going by the name Warszewitsch’s frog all across its known distribution.
Conservation biologist and lead author James Cryer says:
“The next step will be to gather more samples throughout the full range of the species. Additionally, if we are to fully discern one species variant from another, further studies that compare the physical, behavioural and ecological characteristics of the frogs, alongside more genetic testing is needed.”
Overall, findings like these are important to help improve our understanding of amphibian biodiversity and, thus, work towards its conservation.
“If indeed there are multiple species, it may be that they have different ecological requirements, and therefore different approaches to their conservation are needed.” Cryer says. “This study further reinforces the power of DNA barcoding for rapid, preliminary species identification. Especially in the tropics, where habitat loss, climate change and infectious disease continually threaten many undescribed amphibian species.”
Dubbed as ‘the most talked about paper’, the cautionary publication is suggested to have omitted a non-western view on inequality that impedes global sustainability
By pointing out the western lifestyle is not “the norm and end goal of societal evolution”, the research team of Dr Mohsen Kayal (University of Perpignan, France) contributes to the debate on the urgency of achieving sustainability, as ignited by the largely publicised article “World Scientists’ Warning to Humanity: A Second Notice” published in BioScience in 2017. Their Response paper in the open-access journal Rethinking Ecology emphasizes that societies in developing countries are often more dependent on natural resources, while least responsible for the ecological crisis.
While expressing explicit support and endorsement for the call made in the original paper, the team argue that several of its recommendations “address symptoms rather than root causes”, while steering away from historical patterns and underlying drivers of the global socio-economic system, namely those relating to wealth inequality, human demography, and food production.
According to the researchers, the desired universal sustainability cannot be achieved in a situation of inequitable wealth distribution. They highlight the link between the consumerism and neocolonialism in the western society and the environmental declines. Meanwhile, communities in the developing world are much more vulnerable to ecological disasters and their homelands are being overexploited and compromised for the production of a major part of the commodities sold around the world.
Inequitable distribution is also evident in the ecological footprint of the western world as opposed to poorer regions. The team of Dr Mohsen Kayal question the appeal made in the Warning to Humanity paper that restricting birth rates is of primary concern when it comes to mitigating the anthropogenic effect on the planet. Rather, they argue that it is the excessive resource consumption and ecosystem-destructive practices observed in the western lifestyle that need to be prioritized.
Citing the 2017 data from the Food and Agriculture Organization of the United Nations, the authors note that there is indeed enough food being produced to meet the needs of even more people on Earth than there currently are. However, it is again the unequal distribution of resources that results in both hunger and obesity. In the meantime, the replacement of the current industrial model of agriculture with a suite of environmentally friendly practices (e.g. cover crops, diverse crop rotations), the adoption of ecologically-based farming and well-managed grazing could preserve soils and their properties, while also increasing yields, resilience to climate change and socio-economic development.
“Sustainability can only be achieved through prioritizing global ethics, including universal equality and respect for all forms of life,” conclude the authors of the Response paper. “Sustainable solutions to Earth’s socio-ecological crisis already exist, however humanity still needs to realize that pursuing the same practices that created these problems is not going to solve them.”

The endemic reptiles are already proposed to be listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora
While proper information about the conservation status of tiger gecko species is largely missing, these Asian lizards are already particularly vulnerable to extinction, as most of them have extremely restricted distribution. Furthermore, they have been facing severe declines over the last two decades, mostly due to overcollection for the international exotic pet market. Such is the case of the Cat Ba Tiger Gecko, whose tiny populations can only be found on Cat Ba Island and a few islands in the Ha Long Bay (Vietnam).
In their study, a Vietnamese-German research team, led by PhD candidate Hai Ngoc Ngo of the Vietnam National Museum of Nature in Hanoi, provide an overview of the evidence for domestic and international trade in tiger gecko species and update the information about the abundance and threats impacting the subpopulations of the Vietnamese Cat Ba Tiger Gecko in Ha Long Bay.
By presenting both direct and online observations, interviews and existing knowledge, the scientists point out that strict conservation measures and regulations are urgently needed for the protection and monitoring of all tiger geckos. The research article is published in the open-access journal Nature Conservation.

Tiger geckos are a genus (Goniurosaurus) of 19 species native to Vietnam, China and Japan. Many of them can only be found within a single locality, mountain range or archipelago. They live in small, disjunct populations, where the population from Ha Long Bay is estimated at about 120 individuals. Due to demands in the international pet trade in the last two decades, as well as habitat destruction, some species are already considered extinct at the localities where they had originally been discovered.
However, it was not until very recently that some species of these geckos received attention from the regulatory institutions in their home countries, leading to the prohibition of their collection without a permit. Only eight tiger geckos have so far had their species conservation status assessed for the IUCN Red List. Not surprisingly, all of them were classified as either Vulnerable, Endangered or Critically Endangered. Nevertheless, none is currently listed by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which could be the only efficient and reliable method to monitor, regulate and police the trade of the species on a global scale.
“Tiger geckos are neither sufficiently protected by law nor part of conservation programmes, due to the lack of substantial knowledge on the species conservation status and probably due to the general lack of public as well as political interest in biodiversity conservation,” they explain. “To date, exact impacts of trade on the species cannot be identified, as data of legal trade are only recorded for species listed in the CITES Appendices”.
During their survey, the researchers tracked local traders in possession of wild-caught tiger geckos representing all five Vietnamese species en route to foreign exotic pet markets, mainly in the United States, the European Union and Japan. The species were also frequently found to be sold in local pet shops in Vietnam, as well as being offered via various online platforms and social media networks like Facebook.
Having spoken to local dealers in Vietnam, the team found the animals were traded via long and complex chains, beginning from local villagers living within the species’ distribution range, who catch the geckos and sell them to dealers for as little as US$4 – 5 per individual. Then, a lizard either ends up at a local shop with a US$7 – 25 price tag or is either transported by boat or by train to Thailand or Indonesia, from where it is flown to the major overseas markets and sold for anywhere between US$100 and 2,000, depending on its rarity. However, many of these delicate wild animals do not arrive alive at their final destination, as their travels include lengthy trips in overfilled boxes under poor conditions with no food and water.
Indeed, although the researchers reported a large quantity of tiger geckos labelled as captive-bred in Europe, it turns out that their availability is far from enough to meet the current demands.
In conclusion, the team provides a list of several recommendations intended to improve the conservation of the Asian geckos: (1) inclusion of all tiger geckos in the Appendices of CITES; (2) assessment of each species for the IUCN Red List; (3) concealment of any currently unknown localities; and (4) improvement/establishment of coordinated ex-situ breeding programmes for all species.
Signboard handed over to the Ha Long Bay Management Department to point to the threats and conservation need of the Cat Ba tiger gecko in English and Vietnamese languages.
The inclusion of all tiger gecko species from China and Vietnam in CITES Appendix II was recently proposed jointly by the European Union, China and Vietnam and is to be decided upon at the Conference of the parties (CoP18) in May-June 2019, held in Sri Lanka.

The Centre for Agriculture and Bioscience International (CABI) has led an international team of non-native species (NNS) specialists who have compiled a list of recommendations to improve the way in which the impact of a range of invasive pests – such as the tomato leaf miner Tuta absoluta – are assessed, potentially helping towards ensuring greater global food security.
Lead authors Dr Pablo González-Moreno and Dr Marc Kenis, Senior Researchers at CABI are two of 89 NNS experts from around the world who have collaborated on the paper, published in NeoBiota, that calls for ‘more robust and user-friendly’ impact assessment protocols to predict the impacts of new or likely invaders as well as to assess the actual impact of established species.
The manuscript is the outcome of an enormous collective effort using 11 different protocols to assess the potential impact of 57 NNS to Europe yielding a total of 2614 separate assessments. This unique dataset has allowed the authors to identify which are the main factors increasing the robustness of protocols and provide recommendations on how the robustness and applicability of protocols could be enhanced for assessing NNS impacts.
As reported in the study, entitled ‘Consistency of impact assessment protocols for Non-Native Species’, Dr González-Moreno and fellow scientists – from 80 institutions including the UK-based Centre for Ecology & Hydrology (CEH), University of Milan, University of Bern and Queens University Belfast – argue that ‘assessment of the realised or potential impacts of NNS is particularly important for the prioritization of management actions.’
Millions of the world’s most vulnerable people face problems with invasive weeds, insects and plant diseases, which are out of control and have a major impact on global prosperity, communities and the environment. Developing countries are disproportionately affected.
The scientists believe that, currently, the large variety of metrics adopted to measure the impacts of invasive species undermines direct comparison of impacts across species, groups of taxa, localities or regions. They go on to argue that in general we have ‘little understanding of the patterns in consistency of impact scores across assessors and protocols, and more importantly, which factors contribute to high levels of consistency.’
Dr González-Moreno said,
“There is an increasing demand for robust and user-friendly impact assessment protocols to be used by professionals with different levels of expertise and knowledge.
Robust NNS impact protocols should ideally result in accurate and consistent impact scores for a species even if applied by different assessors, as long as they have the adequate expertise in the assessed species and context.
Several key factors should be taken into account when selecting or designing an NNS risk assessment protocol, such as the aim, the scope, the consistency and the accuracy of the outcomes, and the resources available to perform the assessment – for example time or information available.”
In compiling a list of recommendations for improved NNS impact protocols, Dr González-Moreno and the team of researchers used 11 different protocols to assess the potential impact of 57 species not native to Europe and belonging to a very large array of taxonomic groups (plants, animals, pathogens) from terrestrial to freshwater and marine environments.
They agree that using a ‘5-level scoring, maximum aggregation method and the moderation of expertise requirements’ offers a good compromise to reducing inconsistencies in research findings without losing discriminatory power or usability.
Dr González-Moreno added, “In general, we also advise protocol developers to perform sensibility tests of consistency before final release or adoption. This is crucial as if a protocol yields inconsistent outcomes when used by different assessors, then it is likely that decisions taken based on the results could be variable and disproportionate to the actual impacts.”

Earlier this year, a research article triggered a media frenzy by predicting that as a result of an ongoing rapid decline, nearly half of the world’s insects will be no more pretty soon
Query- and geographically-biased summaries; mismatch between objectives and cited literature; and misuse of existing conservation data have all been identified in the alarming study, according to Drs Atte Komonen, Panu Halme and Janne Kotiaho of the University of Jyväskylä (Finland). Despite the claims of the review paper’s authors that their work serves as a wake-up call for the wider community, the Finnish team explain that it could rather compromise the credibility of conservation science.
The first problem about the paper, titled “Worldwide decline of the entomofauna: A review of its drivers” and published in the journal Biological Conservation, is that its authors have queried the Web of Science database specifically using the keywords “insect”, “decline” and “survey”.
“If you search for declines, you will find declines. We are not questioning the conclusion that insects are declining,” Komonen and his team point out, “but we do question the rate and extent of declines.”
Many butterflies have declined globally. Scolitantides orion, for example, is an endangered species in Finland. Photo by Atte Komonen.
The Finnish research team also note that there are mismatches between methods and literature, and misuse of IUCN Red List categories. The review is criticised for grouping together species, whose conservation status according to the International Union for Conservation of Nature (IUCN) is Data Deficient with those deemed Vulnerable. By definition, there are no data for Data Deficient species to assess their declines.
In addition, the review paper is seen to use “unusually forceful terms for a peer-reviewed scientific paper,” as the Finnish researchers quote a recent news story published in The Guardian. Having given the words dramatic, compelling, extensive, shocking, drastic, dreadful, devastating as examples, they add that that such strong intensifiers “should not be acceptable” in research articles.
“As actively popularising conservation scientists, we are concerned that such development is eroding the importance of the biodiversity crisis, making the work of conservationists harder, and undermining the credibility of conservation science,” the researchers explain the motivation behind their response.

The World Register of Marine Species (WoRMS) announced the
Top 10 Marine Species of 2018 just in time for
Taxonomist Appreciation Day
What could be better timing to take a look back on the most spectacular animals described as new to science throughout 2018 than 19th March, Taxonomist Appreciation Day?
For the sixth time around, biologists from across the world are all hyped-up about this special date when we celebrate the experts who put things in order by giving names, identities and belonging to what the world has thought non-existent only a moment ago. After all, no sooner is a species formally acknowledged than it can be studied, understood and protected.
Having said that, at Pensoft and ZooKeys we’re immensely proud of becoming a prime publication choice for marine taxonomists from around the globe. Amongst them are the authors of not one or two, but FIVE exceptional animal curiosities, now recognised by a selected committee and the World Register of Marine Species (WoRMS), and featured in the TOP 10 Marine Species of 2018.
The “Japan Pig” which is also a… seahorse (Hippocampus japapigu)

We fail to find the obvious reason why locals diving in the waters of Hachijo-jima Island (Japan) had already likened this dazzling seahorse to a “tiny baby pig”, when a research team collected specimens and identified them as a species new to science. Naturally, the scientists assigned it with the name japapigu, which translates to “Japan Pig” in Japanese.
One thing is for sure, though, the stunning seahorse wouldn’t demand a degree in Zoology to attract anyone’s attention, had it not been for its expertise in camouflaging itself against the colourful algae-covered rocks.

The crab that chooses an animal ‘blanket’ over a shell (Paguropsis confusa)
Photo by DST/NRF ACEP – Spatial Solutions project team.
Sure, who would go for a rigid shell left behind by a random gastropod – just like “ordinary” hermit crabs do – when they could reach for a light, soft and elastic “blanket” instead?
That’s exactly what the blanket-hermit crab Paguropsis confusa and its sibling species have been doing as they evolved to live in a cosy symbiosis with sea anemones. While the translucent anemone peacefully “shares” the crab’s meals and grows its zoophytes around the soft-bodied crustacean, the latter is free to easily draw them up and down – as if they were a real silky duvet – and even completely cover its head whenever it feels threatened.
The crab species name is“confuso”in reference to its morphological resemblance to the closely related species Paguropsis typica. In fact, had it not been for the similarity, what we now call Paguropsis confuso would’ve most likely been described well over a century ago.
I was previously unaware of the 'blanket hermit crab,' which gently tugs an anemone up around its body like a cozy snuggly blanket and WAIT WHAT???
Amidst ongoing talks and grim forecasts of declining coral reefs spelling demise for the world as we know it, the discovery of this endemic to Okinawa Island (Japan) flower-like octocoral comes as a stunning reminder of Nature’s supremacy.
Described as a new genus, as well as a species new to science, the octocoral was aptly named Hana hanagasa, where “Hana”translates to “flower” in Japanese, while “hanagasa” is a traditional Okinawan headpiece, crafted in the form of hibiscus and worn by female dancers at ceremonies.

Upon writing up the description of this species of Indonesian shrimp,Leiden University’s then BSc student Werner de Gier is unlikely to have thought twice before coming up with the name bagginsi, as in Frodo and Bilbo Baggins – the most famous hobbits from J. R. R.Tolkien’s The Lord of the Rings and The Hobbit.
After all, what the researcher was looking at was a creature tiny enough to call another marine invertebrate – a tunicate – its snug home. Also, it had extremely hairy feet, a feature that would require for the identification key for all members of the species group to be updated.

One might think that an animal as large as a shark – especially if it’s the only shark species found in the waters of the Hawaiian Archipelago – would’ve “told” all its “secrets” by now, but that wasn’t the case with what we now refer to as the Hawaiian Spurdog.
Long mistaken for a stray population of a dogfish shark species originally from Japan, it wasn’t before US scientists deployed a range of elaborate tools used in species identification that it became apparent there was a previously unknown to science, short-ranged endemic shark trying to find shelter in Hawai’i.
Sadly, while the species is being depleted as bycatch, it has also demonstrated the lowest rate of genetic diversity known in a shark population to date.
#NewSpecies of deep-water dogfish #shark endemic to #Hawaii had previously been mistaken for the Shortspine #Spurdog originally described from Japanese waters.
Let us conclude with the words of ecologists and entomologist Dr Terry McGlynn, who started the Taxonomist Appreciation Day tradition in 2013:
“Even if you’re working on a single-species system, or are a theoretician, the discoveries and methods of systematists are the basis of your work,” he once told the Consortium of European Taxonomic Facilities (CETAF). “We need active work on taxonomy and systematics if our work is going to progress, and if we are to apply our findings. Without taxonomists, entire fields wouldn’t exist. We’d be working in darkness”.

The new species are amongst the very first bald-legged spiders recorded in Colombia
Despite being widely distributed across north and central South America, bald-legged spiders had never been confirmed in Colombia until the recent study by the team of Drs Carlos Perafan and Fernando Perez-Miles (Universidad de la Republica, Uruguay) and William Galvis (Universidad Nacional de Colombia). Published in the open-access journal ZooKeys, their research paper describes a total of six previously unknown species inhabiting the country.
Four of the novel spiders were unable to fit into any already existing genus, so the scientists had to create a brand new one for them, which they called Stormtropis in reference to the Star Wars‘ clone trooper army known as Stormtroopers.
Considered to be amongst the most enigmatic in the group of mygalomorphs, the bald-legged spiders are a family of only 11 very similarly looking, small- to medium-sized species, whose placement in the Tree of Life has long been a matter of debate. In fact, it is due to their almost identical appearance and ability for camouflage that became the reason for the new bald-legged spider genus to be compared to the fictional clone troopers.
One of the most striking qualities of the bald-legged spiders (family Paratropididae) is their ability to adhere soil particles to their cuticle, which allows them to be camouflaged by the environment.

“The stormtroopers are the soldiers of the main ground force of the Galactic Empire. These soldiers are very similar to each other, with some capacity for camouflage, but with unskillful movements, like this new group of spiders,” explain the researchers.
“We wanted to make a play on words with the name of the known genus, Paratropis, and of course, we also wanted to pay tribute to one of the greatest sagas of all time”, they add.
One of the new ‘stormtrooper’ species (Stormtropis muisca) is also the highest altitudinal record for the family. It was recorded from an elevation of at least 3,400 m in the central Andes. However, the authors note that they have evidence of species living above 4,000 m. These results are to be published in future papers.
In the course of their fieldwork, the researchers also confirmed previous assumptions that the bald-legged spiders are well adapted to running across the ground’s surface. The spiders were seen to stick soil particles to their scaly backs as a means of camouflage against predators. More interestingly, however, the team records several cases of various bald-legged species burrowing into ravine walls or soil – a type of behaviour that had not been reported until then. Their suggestion is that it might be a secondary adaptation, so that the spiders could exploit additional habitats.
In conclusion, not only did the bald-legged spiders turn out to be present in Colombia, but they also seem to be pretty abundant there. Following the present study, three genera are currently known from the country (Anisaspis, Paratropis and Stormtropis).

Data audit workflow provided for data papers submitted to Pensoft journals.
To avoid publication of openly accessible, yet unusable datasets, fated to result in irreproducible and inoperable biological diversity research at some point down the road, Pensoft takes care for auditing data described in data paper manuscripts upon their submission to applicable journals in the publisher’s portfolio, including Biodiversity Data Journal, ZooKeys, PhytoKeys, MycoKeys and many others.
Once the dataset is clean and the paper is published, biodiversity data, such as taxa, occurrence records, observations, specimens and related information, become FAIR (findable, accessible, interoperable and reusable), so that they can be merged, reformatted and incorporated into novel and visionary projects, regardless of whether they are accessed by a human researcher or a data-mining computation.
As part of the pre-review technical evaluation of a data paper submitted to a Pensoft journal, the associated datasets are subjected to data audit meant to identify any issues that could make the data inoperable. This check is conducted regardless of whether the dataset are provided as supplementary material within the data paper manuscript or linked from the Global Biodiversity Information Facility (GBIF) or another external repository. The features that undergo the audit can be found in a data quality checklist made available from the website of each journal alongside key recommendations for submitting authors.
Once the check is complete, the submitting author receives an audit report providing improvement recommendations, similarly to the commentaries he/she would receive following the peer review stage of the data paper. In case there are major issues with the dataset, the data paper can be rejected prior to assignment to a subject editor, but resubmitted after the necessary corrections are applied. At this step, authors who have already published their data via an external repository are also reminded to correct those accordingly.
“It all started back in 2010, when we joined forces with GBIF on a quite advanced idea in the domain of biodiversity: a data paper workflow as a means to recognise both the scientific value of rich metadata and the efforts of the the data collectors and curators. Together we figured that those data could be published most efficiently as citable academic papers,” says Pensoft’s founder and Managing director Prof. Lyubomir Penev.
“From there, with the kind help and support of Dr Robert Mesibov, the concept evolved into a data audit workflow, meant to ‘proofread’ the data in those data papers the way a copy editor would go through the text,” he adds.
“The data auditing we do is not a check on whether a scientific name is properly spelled, or a bibliographic reference is correct, or a locality has the correct latitude and longitude”, explains Dr Mesibov. “Instead, we aim to ensure that there are no broken or duplicated records, disagreements between fields, misuses of the Darwin Corerecommendations, or any of the many technical issues, such as character encoding errors, that can be an obstacle to data processing.”
At Pensoft, the publication of openly accessible, easy to access, find, re-use and archive data is seen as a crucial responsibility of researchers aiming to deliver high-quality and viable scientific output intended to stand the test of time and serve the public good.
