New partnership between Pensoft and BEXIS 2 encourages Data Paper publications

Following the new partnership between the German open source platform BEXIS 2 and the academic publisher Pensoft, scientists are now able to publish data papers in three of the most innovative Pensoft journals: Biodiversity Data Journal (BDJ)One Ecosystem and Metabarcoding and Metagenomics (MBMG), using EML data packs from BEXIS 2.

In order to encourage and facilitate high-quality data publication, the collaboration allows for researchers to easily store, analyse and manage their data via BEXIS 2, before sharing it with the scientific community in a creditable format.

The newly implemented workflow requires researchers to first download their data from the free open source BEXIS 2 software and, then, upload the data pack on Pensoft’s ARPHA Journal Publishing Platform where the data can be further elaborated to comply to the established Data Paper standards. Within the software, they can work freely on these data.

Having selected a journal and a data paper article template, a single click at an ‘Import a manuscript’ button transfers the data into a manuscript in ARPHA Authoring Tool. Within the collaborative writing tool, the data owner can invite co-authors and peers to help him/her finalise the paper.

Once submitted to a journal, the article undergoes a peer review and data auditing and, if accepted for publication, is published to take advantage of all perks available at any Pensoft journal, including easy discoverability and increased citability.

“I am delighted to have this new partnership between Pensoft and BEXIS 2 announced,” says Pensoft’s founder and CEO Prof. Lyubomir Penev.

“I believe that workflows like ours do inspire scientists to, firstly, refine their data to the best possible quality, and, secondly, make them available to the world, so that these data can benefit the society much faster and more efficiently through collaborative efforts and constructive feedback.”

“With scientists becoming more and more eager to publish research data in data journals like Pensoft’s BDJ, it is important to provide comprehensive and easy workflows for the transition of data from a data management platform like BEXIS 2 to the repository of the data journal without losing or re-entering any information. So we are absolutely delighted that a first version of such data publication workflow is now available to users of BEXIS 2.” says Prof. Birgitta König-Ries, Principle Investigator of BEXIS 2.

The collaboration between Pensoft and BEXIS 2 is set to strengthen in the next few months, when a new import workflow is expected to provide an alternative way to publish datasets.

In 2015, Pensoft launched similar workflows for DataONE, the Global Biodiversity Information Facility (GBIF) and the Long Term Ecological Research Network (LTER).

New butterfly species discovered in Russia with an unusual set of 46 chromosomes

What looked like a population of a common butterfly species turned out to be a whole new organism, and, moreover – one with a very peculiar genome organisation.

Discovered by Vladimir Lukhtanov, entomologist and evolutionary biologist at the Zoological Institute in St. Petersburg, Russia, and Alexander Dantchenko, entomologist and chemist at the Moscow State University, the startling discovery was named South-Russian blue (Polyommatus australorossicus). It was found flying over the northern slopes of the Caucasus mountains in southern Russia. The study is published in the open access journal Comparative Cytogenetics.

“This publication is the long-awaited completion of a twenty-year history,” says Vladimir Lukhtanov.

In the mid-nineties, Vladimir Lukhtanov, together with his students and collaborators, started an exhaustive study of Russian butterflies using an array of modern and traditional research techniques. In 1997, Alexander Dantchenko who was mostly focused on butterfly ecology, sampled a few blue butterfly specimens from northern slopes of the Caucasus mountains. These blues looked typical at first glance and were identified as Azerbaijani blue (Polyommatus aserbeidschanus).

However, when the scientists looked at them under a microscope, it became clear that they had 46 chromosomes – a very unusual number for this group of the blue butterflies and exactly the same count as in humans.

Having spent twenty years studying the chromosomes of more than a hundred blue butterfly species and sequencing DNA from all closely related species, the researchers were ready to ascertain the uniqueness of the discovered butterfly and its chromosome set.

Throughout the years of investigation, it has become clear that caterpillars of genetically related species in the studied butterfly group feed on different, but similar plants. This discovery enables entomologists to not only discover new butterfly species with the help of botanic information, but also protect them.

“We are proud of our research,” says Vladimir Lukhtanov. “It contributes greatly to both the study of biodiversity and understanding the mechanisms of biological evolution.”

Swiss-born rebranded Alpine Entomology journal joins Pensoft’s open access portfolio

Formerly dedicated to all fields in entomology, the journal now focuses on insect research from mountainous regions from around the world

Launched about a century and a half ago, the Swiss Entomological Society‘s official journal Die Mitteilungen der Schweizerischen Entomologischen Gesellschaft (Journal of the Swiss Entomological Society) is the latest historical scientific journal to join the lines of Pensoft’s portfolio.

As a result of an unanimous vote at the Swiss Entomological Society’s general assembly in March, the journal is now rebranded as Alpine Entomology to reflect the shift in its scope and focus. Furthermore, the renowned journal is also changing its format, submission and review process, “in accordance with the standards of modern scientific publishing”, as explained in the inaugural Editorial.

The first articles of Alpine Entomology in partnership with Pensoft are already live on the journal’s new website.

“Focusing the scope will improve the quality of the journal and of the submitted papers and therefore increase the impact in the scientific community,” say Dr. Thibault Lachat, Bern University of Applied Sciences and Swiss Federal Institute for Forest, Snow and Landscape Research, and Hannes Baur, Natural History Museum of Bern, and University of Bern.

Alpine Entomology now accommodates a long list of high-tech perks and brand new looks thanks to the innovative journal publishing platform ARPHA – the Pensoft-developed innovative journal publishing platform.

Nonetheless, the journal preserves its well-respected expertise and dedication to original research on the insect fauna. Occasionally, it will be also publishing studies on other arthropods from the Alpine region or other mountainous regions all over the world.

Apart from the all-new look and feel visible at first glance, there are many technologically-advanced innovations to benefit authors, readers, reviewers and editors alike.

Thanks to the fast-track and convenient publishing provided by ARPHA, each manuscript is carried through all stages from submission and reviewing to dissemination and archiving without ever leaving the platform’s singular collaboration-friendly online environment.

Once published, all articles in Alpine Entomology are to be available in three formats (PDF, XML, HTML), enriched with a whole set of semantic enhancements, so that the articles are easy to discover, access and harvest by both humans and machines.

Amongst the first papers, there are descriptions of several new mountainous species from around the world that have remained unknown to science until very recently. Two separate papers describe two new species of long-legged flies from Turkey and Croatia, respectively; while a third one reports a new ground beetle dwelling in Bhutan’s Thrumshingla National Park.

“I’m delighted to welcome this particular new member of the Pensoft’s and ARPHA’s family,” says the publisher’s founder and CEO Prof. Lyubomir Penev. “With our own solid experience in both scholarly publishing and entomological research, I’m certain that we’ll be able to provide the right venue for a fantastic title as Alpine Entomology.

“This year sees a lot of changes for the Swiss Entomological Society‘s signature journal, which I believe are all extremely positive,” says Alpine Entomology‘s Editor-in-Chief Dr. Thibault Lachat. “By making use of the modern, technologically advanced open access publishing provided by ARPHA and Pensoft, I’m convinced that our journal will increase its visibility and gain an international reputation in the entomological community.”

Poison ivy an unlikely hero in warding off exotic invaders?

Dozens of studies have looked at the effects of Japanese knotweed on natural communities in Europe and North America. Yet Bucknell University professor Chris Martine still felt there was something important to learn about what the plant was doing along the river in his own backyard.

“The more time I spent in the forests along the Susquehanna River, the more it seemed like something was really going wrong there,” said Martine. “In addition to the prevalence of this single invasive species, it looked like the very existence of these forests was under threat.”

What Martine noticed was similar to what local nature lovers and biologists with the Pennsylvania Natural Heritage Program were also starting to see: these forests, specifically those classified as Silver Maple Floodplain Forests, were not regenerating themselves where knotweed had taken a foothold.

In a new study published in the open access Biodiversity Data Journal, Martine and two recent Bucknell alumni conclude that Japanese knotweed has not only excluded nearly all of the native understory plant species in these forests, but it has prevented the trees already established in the canopy from leaving behind more of themselves.

“If you were to fly over these forests, or even look at a Google Earth image, you’d see a nice green canopy along the river consisting of mature silver maples, river birches, and sycamores,” explained Martine. “But below that canopy there is almost nothing for tens of feet before you reach an eight-to-twelve-foot-tall thicket of knotweed. Few new trees have been able to grow through that in the last 50-60 years and our surveys found that seedlings of these species are quite rare.”

The authors suggest that as mature trees die of natural causes over the next several decades and are not replaced, these systems will shift from tree-dominated riverbank habitats to “knotweed-dominated herbaceous shrublands” incapable of supporting a rich diversity of insects, birds, and other wildlife. Loss of trees in these habitats could likely also lead to riverbank erosion and increase the severity of flood events.

The few places where knotweed has not taken over offer a bit of hope, however, from an unlikely hero: poison-ivy, which Martine calls “perhaps the least popular plant in America.”

“What we see in the data is that poison-ivy often trades understory dominance with knotweed. That is, when knotweed isn’t the big boss, poison-ivy usually is. The difference is that whereas knotweed knocks everyone else out of the system, poison-ivy is more of a team player. Many other native plants can co-occur with it and it even seems to create microhabitats that help tree seedlings get established.”

The prevalence of poison-ivy in these sites didn’t go unnoticed by undergraduate Anna Freundlich, who collected most of the plant community data — more than 1,000 data points — in a single summer as a research fellow.

“Anna developed a pretty serious methodology for avoiding a poison-ivy rash that included long sleeves, long pants, gloves, duct tape, and an intense wash-down protocol,” said her research advisor, “and even after crawling through the plant for weeks she managed to never once get a rash.”

Martine cautions against too much optimism regarding the chances of one itch-inducing native plant saving the day, however.

“Righting this ship is going to require eradicating knotweed from some of these sites, and that won’t be easy work. It will take some hard manual labor. But it’s worth doing if we want to avoid the imminent ecological catastrophe. These forests really can’t afford another half-century of us letting knotweed run wild.”

Freundlich is a now pursuing a Master’s degree in plant ecology at the University of Northern Colorado. Lead author Matt Wilson, a Bucknell Master’s student at the time of the study who analyzed the dataset, now works for the Friends of the Verde River in Cottonwood, AZ.

About Japanese knotweed:

Japanese knotweed is considered to be one of the toughest, most damaging and insidious plants in the world. Native to East Asia, the species has already established successfully in many parts throughout North America and Europe, where it can easily grow and invade private properties and homes. It is hardy enough to penetrate patios, house foundations and concrete. Given it spreads easily and can grow underground to a depth of 3 metres with a horizontal range of up to 7 metres, it is extremely difficult to eradicate and its treatment requires special attention. To find advice on recognition, hazards and treatment, you can check out The Ultimate Japanese Knotweed Guide.

A genus of European paper wasps revised for the first time using integrative taxonomy

The European and Mediterranean species of the paper wasp genus Polistes were recently revised by scientists at the SNSB-Zoologische Staatssammlung München (ZSM).

For the first time for this group scientists applied an integrative taxonomic approach which combines traditional morphological methods with modern DNA barcoding.

As a result, the researchers were able to identify a new species from Morocco. For this well-researched wasp group, this is an actual sensation.

The study is published in the open access journal ZooKeys.

The Munich researchers analysed more than 260 wasp specimens collected from across the study area with the help of DNA barcoding.

They managed to identify all species and determine their distribution. In addition, based on the genetic data, they were able to evaluate morphological characters for each species and created a completely new key for identification.

The wasps of the genus Polistes belong to the family Vespidae. The genus is represented by 17 species in Europe and the Mediterranean, with four species occurring in Germany. Within the genus, 13 species are social, with the queen overwintering and founding a new nest with up to 200 workers. Four species are parasitic and have no workers.

Although Polistes has been well-known in Central Europe for more than 200 years, knowledge of Mediterranean species has so far been scarce. Many species of the genus exhibit only subtle morphological differences and show high levels of colour variation, further complicating their identification.

An important result of this research is the separation of species of the Polistes gallicus species complex into three distinct species. Moreover, the genetic data led to the discovery of a new species, represented by a single specimen from the High Atlas Mountains in Morocco. This was an unexpected result for the researchers. The species was named Polistes maroccanus.

Another very surprising result was the discovery of high levels of genetic variation within Polistes dominula, a species commonly found in Central Europe, indicating the presence of up to three different and hitherto unrecognized species – a case requiring further investigation.

Integrative taxonomy is an approach that combines different scientific methods to reliably differentiate species. In particular, DNA barcoding has proven to be a useful technique for the identification of species and for the discovery of new species. The method allows to identify most species quickly and accurately, even those species that are difficult to identify using traditional methods based on morphological characters.

DNA barcoding uses a short gene fragment that differs in almost all species worldwide. The sequences are stored in an online database and can be used for identification. The method derives its name for being reminiscent of the barcodes similar to those found on products in supermarkets that allow quick and error-free identification at the checkout.

DNA barcoding is part of a global research initiative led by the Canadian scientist Paul Hebert from the University of Guelph. The ZSM is a project partner and involved in assembling DNA barcodes of the German animal species. In addition to ZSM researchers, scientists from Switzerland and the Netherlands contributed to the Polistes project.

Artificial neural networks could power up curation of natural history collections

Deep learning techniques manage to differentiate between similar plant families with up to 99 percent accuracy, Smithsonian researchers reveal

Millions, if not billions, of specimens reside in the world’s natural history collections, but most of these have not been carefully studied, or even looked at, in decades. While containing critical data for many scientific endeavors, most objects are quietly sitting in their own little cabinets of curiosity.

Thus, mass digitization of natural history collections has become a major goal at museums around the world. Having brought together numerous biologists, curators, volunteers and citizens scientists, such initiatives have already generated large datasets from these collections and provided unprecedented insight.

Now, a study, recently published in the open access Biodiversity Data Journal, suggests that the latest advances in both digitization and machine learning might together be able to assist museum curators in their efforts to care for and learn from this incredible global resource.

A team of researchers from the Smithsonian Department of BotanyData Science Lab, and Digitization Program Office recently collaborated with NVIDIA to carry out a pilot project using deep learning approaches to dig into digitized herbarium specimens.

Their study is among the first to describe the use of deep learning methods to enhance our understanding of digitized collection samples. It is also the first to demonstrate that a deep convolutional neural network–a computing system modelled after the neuron activity in animal brains that can basically learn on its own–can effectively differentiate between similar plants with an amazing accuracy of nearly 100%.

In the paper, the scientists describe two different neural networks that they trained to perform tasks on the digitized portion (currently 1.2 million specimens) of the United States National Herbarium.

The team first trained a net to automatically recognize herbarium sheets that had been stained with mercury crystals, since mercury was commonly used by some early collectors to protect the plant collections from insect damage. The second net was trained to discriminate between two families of plants that share a strikingly similar superficial appearance.

The trained neural nets performed with 90% and 96% accuracy respectively (or 94% and 99% if the most challenging specimens were discarded), confirming that deep learning is a useful and important technology for the future analysis of digitized museum collections.

“The results can be leveraged both to improve curation and unlock new avenues of research,” conclude the scientists.

“This research paper is a wonderful proof of concept. We now know that we can apply machine learning to digitized natural history specimens to solve curatorial and identification problems. The future will be using these tools combined with large shared data sets to test fundamental hypotheses about the evolution and distribution of plants and animals,” says Dr. Laurence J. Dorr, Chair of the Smithsonian Department of Botany.

When lemons give you life: Herpetofauna adaptation to citrus orchards in Belize

Natural habitat areas exhibit similar abundances and diversity of herpetofauna as citrus orchards and reclaimed orchard forests in Stann Creek, Belize, reports a comparative study by researchers Russell Gray and Dr. Colin Strine of Suranaree University of Technology (SUT), Thailand.

The scientists utilized several drift-fence arrays equipped with double-funnel traps to monitor and compare reptile and amphibian communities in a lowland broadleaf forest, a lime orchard and a reclaimed citrus orchard at the Toucan Ridge Ecology and Education Society (TREES) field station. Their study was recently published in the open-access journal ZooKeys.

Often referred to as Central America’s “hidden gem” for its abundance of undisturbed rainforests and natural beauty, Belize has a long-standing record for vigorously protecting and maintaining their forested areas. However, just as in any other developing country, its primary sector is expanding with agricultural land clearings becoming more frequent with newly established properties.

Approximately midway through the study (June – September 2016), the site was hit by Hurricane Earl, a Category 1 hurricane. The hurricane-force winds altered the canopy cover significantly over the forested study sites, due to felled trees and broken branches.

Surprisingly enough, the herpetofauna remained relatively unchanged in the aftermath of Earl. The phenomenon revealed that not only were herpetofaunal communities lacking sensitivity to anthropogenic changes in the area, but also to extreme weather events, even though these had affected most of the standing vegetation.

Some notable observations occurred within three days of Hurricane Earl, according to Russell Gray:

“One of the trapping system was catching arboreal [tree climbing] snake species, like the cat-eyed snake and blunt-headed tree snake. This wasn’t only interesting because arboreal snakes were caught in terrestrial traps, but rather because they were never caught in our traps during the study up to this point.”

“Even more interesting is that they were caught exclusively in the manicured orchard area, which makes me wonder if they somehow predicted falling trees and fled to the only habitat without them. Some animals appear to forecast weather events due to sudden or drastic changes in environmental conditions. I wonder if this is a similar case.”

Amongst other notable scientific discoveries reported during the project were two new accounts of the Petén Centipede Snake (Tantilla hendersoni), one of which was the first documented male of the species. This secretive snake had only been documented once prior to the study and is the only endemic snake species to Belize.

Further noteworthy instances were two range extensions for relatively data deficient species – one for the Doflein’s Salamander (Bolitoglossa dofleini) and another for the Ringneck Coffee Snake (Ninia diademata).

Besides providing important data on herpetofauna assemblages in various disturbed and undisturbed habitats in Belize, the research identifies future conservation methods to be considered.

The study serves as new evidence that as long as agricultural areas remain surrounded with natural habitat buffers, they have little effect on herpetofaunal communities.

Replicates of this study are encouraged by the authors and can be utilized as a feasible and efficient way to monitor reptiles and amphibians in Belize.

Although Belize still preserves a considerable amount of intact forest cover, there are several on-going conservation concerns. Besides agricultural land clearings, there are constant struggles with xate poachers, or “Xateros”, on the Guatemalan border, as well as illegal logging activities and illegal off-season hunting.

Unfortunately, reptiles and amphibians have been understudied in comparison to other vertebrates and government action is rarely enforced on their conservation throughout the Neotropics.

A striking example of this relates to the only critically endangered reptile in Belize – the Hickatee turtle (Dermatemys mawii). Although the species is likely to become extinct, it is still traditionally collected for its culinary value, while its hunting is banned only in May.

In conclusion, the authors note that it is crucial to pay close attention to anthropogenic activity and the potential repercussions it may have on native species. With extensive and active efforts to study Mesoamerican herpetofauna, proper conservation efforts can be implemented and focused.

DNA study in the Pacific reveals 2000% increase in our knowledge of mollusc biodiversity

Scientists working in the new frontier for deep-sea mining have revealed a remarkable 2000% increase in our knowledge of the biodiversity of seafloor molluscs.

Tweny-one species, where only one was previously known, are reported as a result of the research which applied the latest DNA-taxonomy methodology to mollusc specimens collected from the central Pacific Clarion Clipperton Zone (CCZ) in 2013. They are all described in the open access journal ZooKeys.

Among the discoveries is a monoplacophoran mollusc species regarded as a ‘living fossil’, since it is one the ancestors of all molluscs. This is the first DNA to be collected from this species and the first record of it from the CCZ mining exploration zone – a vast 5-million-km² region of the central Pacific that is regulated for seabed mining by the International Seabed Authority.

“Despite over 100 survey expeditions to the region over 40 years of mineral prospecting, there has been almost no taxonomy done on the molluscs from this area,” says lead author Dr Helena Wiklund of the The Natural History Museum in London (NHM).

Dr Wiklund undertook a comprehensive DNA-based study of the molluscs to confirm species identities and make data available for future taxonomic study. This was coupled with the expertise of the NHM’s Dr John Taylor, who led the morphological work.

The molluscs were found in samples taken on and in the mud surrounding the potato-sized polymetallic nodules that are present in high abundance across the CCZ. These nodules are the target for potential deep-sea mining being rich in cobalt, copper, nickel, manganese and other valuable minerals.

The data are vital for the future environmental regulation of deep-sea mining, but have also revealed surprising patterns.

“I was amazed to discover that specimens collected during the 19th century by HMS Challenger were probably the same as ours over a range of 7000 km, but that data lodged on genetic databases from closer but shallower depths is likely to be from a different species,” comments Dr Thomas Dahlgren, population geneticist at Uni Research, Norway and University of Gothenburg, Sweden, who studied in detail a species called Nucula profundorum.

“Our efforts are now focussing on studying the DNA from many more samples of this species to examine connectivity and potential resilience to deep-sea mining,” he added.

“It is a simple truth that we cannot move forward on regulatory approval for deep-sea mining without fundamental baseline data on what animals actually live in these regions,” says Principal Investigator of the NHM Deep-sea Systematics and Ecology Research Group, Dr Adrian Glover.

“Our work has highlighted obvious gaps in our knowledge, but also shown that with even relatively modest effort, we can greatly increase our understanding of baseline biodiversity using DNA-taxonomy.”

Creating a library of archived DNA-sequenced samples from known species allows for the future possibility of using the latest environmental DNA (eDNA) methods to ‘search’ for these species using just tiny samples of mud or seawater.

“Its akin to forensic science’, says Dr Glover. “You can’t use eDNA to find the criminals or species unless you have a library of information to compare them too”.

All data and specimens from the study have been lodged at the NHM and online repositories to make them accessible for future study. Of particular importance are the frozen tissue collections, which are housed in the state-of-the-art Molecular Collections Facility at the NHM and available for loan or further DNA work.

Two Caribbean bird-catcher trees named after two women with overlooked botanical work

Known for their biodiversity richness, the Caribbean Islands are now adding two new species of bird-catcher trees to their list of botanical treasures. Commonly referred to as bird-catcher trees, the species whose ripe fruits are sticky and can be glued to birds, are from the four-o’clock family (Nyctaginaceae) and only found in Puerto Rico.

Baptised Pisonia horneae and Pisonia roqueae by authors Marcos A. Caraballo-Ortiz, doctoral candidate at The Pennsylvania State University, US and Jorge C. Trejo-Torres, researcher at The Institute for Regional Conservation in Florida, US, the two unusual trees were named to honor the unrecognised work of two extraordinary self-driven women who devoted decades on educational projects in botany. The research was published in the open access journal Phytokeys.

“Finding large organisms new to science from a relatively small and well-studied island seems implausible, but this recent naming of the two large trees from Puerto Rico proves that explorations in nature and museums can still produce exciting novelties.” explains Trejo-Torres.

The two new trees belong to an extraordinary genus (Pisonia), containing rare plants mainly known for the ability to tangle birds with their sticky fruits, which inspired the common name “bird-catcher” used in the Pacific region. Characteristic for the two new trees are also swollen trunks that wrap over the rocks resembling an elephant foot with toes.

“Birds are the main dispersal agents for Pisonia trees, carrying the sticky fruits glued to their feathers to distant islands. However, sometimes these fruits can trap too tightly and even kills birds, as seen in documentaries.” remarks lead author, Caraballo-Ortiz. “So far, we do not know of cases where birds have been trapped by the sticky fruits of the new species, but future studies will explore this possibility”

One of the trees, Pisonia horneae, is dedicated to Frances W. Horne (1873-1967), an American illustrator who spent 45 years painting 750 watercolors of plants from Puerto Rico, of which only a small fraction were published. The other tree, Pisonia roqueae, was named after Dr. Ana Roqué de Duprey (1853-1933), a Puerto Rican educator, writer, and suffragist. As an amateur ethnobotanist, she spent over three decades to prepare a manuscript aimed to make botany accessible to the general public, which was never published.

“It only seemed natural to name the two new species after these two extraordinary women who spent decades on large educational projects aimed to divulge botanical knowledge in Puerto Rico.” explains Trejo-Torres. “Just like the two large trees remained unrecognised by science until now, the enormous efforts of these two women, who dedicated part of their lives to botanical work, remained largely unrecognised by the community.”

“The scientific relevance of naming these trees is that they thrive in the Puerto Rican forests, including the Luquillo Mountains, which are among the most well studied areas in the world. World-scattered ecologists and conservationists actively working on Puerto Rican forests and plants now have a nice and surprising update to make in their databases.” concluded Caraballo-Ortiz.

New open-access journal Metabarcoding & Metagenomics joins the lines of publisher Pensoft

The new innovative academic journal makes use of the one-of-a-kind publishing platform ARPHA and its collaborative writing tool via the ARPHA-XML workflow

A new innovative open-access academic journal Metabarcoding and Metagenomics (MBMG) is launched to welcome novel papers from both basic and applied aspects.

Focusing on genetic approaches to study biodiversity across all ecosystems, MBMG covers a considerably large scope of research including environmental, microbial and applied metabarcoding and metagenomics (especially DNA-based bioassessment and -monitoring, quarantine, nature conservation, species invasions, eDNA surveillance), as well as associated topics, such as molecular ecology, DNA-based species delimitation and identification, and other emerging related fields. Submissions of bioinformatic approaches to MBMG (algorithms, software) are also encouraged.

Featuring novel article formats and data publishing workflows, MBMG is to reflect the rapid growth in the use of metabarcoding and metagenomics in life and environmental sciences.

Issued via ARPHA – the first ever publishing platform to support manuscripts all the way from authoring to peer review to publication and dissemination, designed by the academic publisher and technology provider Pensoft, the new journal is to host a wide range of outcomes from across the research cycle, including data, models, methods, workflows, software, perspectives, opinions, implementation strategies, as well as conventional research articles.

While the above-mentioned publication types are already available in other journals published on the ARPHA platform, such as Research Ideas and Outcomes (RIO)Biodiversity Data Journal and One Ecosystem, MBMG provides five extra domain-specific article types, namely: Emerging Technique, Applied Study, DNA Barcode Release, Primer Validation and Probe Validation.

The journal’s articles are to be available in three formats (PDF, XML, HTML) and full of semantic enhancements for better human- and machine-readability and discoverability. The XML-based workflow also ensures that content and data are available for extraction, indexing and re-use immediately after publication.

With Pensoft standing for transparent, reproducible and open science, the authors at MBMG are strongly encouraged to make all data publicly available either within the publication itself, or to link to external repositories. In their turn, the peer reviewers are also suggested to provide public access to their reviews and identities.

In time for the launch, MBMG has already gathered a team of experienced and renowned scientists from across the globe together on its editorial and advisory board.

“I am pleased to introduce the Metabarcoding and Metagenomics journal to the family of Pensoft,” says Prof. Lyubomir Penev, Founder and Managing Director at Pensoft. “With its exhaustive scope and advanced services and concept, I believe it fills fantastically a niche in our strong portfolio of mostly biodiversity- and ecology-themed journals.”

“Metabarcoding and metagenomics approaches are rapidly progressing and revolutionise research and its application alike,” Chief Editor Prof. Florian Leese states. “With the MBMG journal we provide an ideal platform to respond to this rapidly growing field, nucleate the emerging knowledge and stimulate further development.”

The first batch of research papers published in MBMG are now available on their new website.

“MBMG not only complements the range of journals in the field of molecular environmental life sciences, but also stands out as a novel outlet providing several unique features designed to help researchers to prepare for, and professionally deal with, the massive “deluge” of data,” reads the Editorial.

To celebrate the launch, MBMG starts with a tempting offer to potential authors: publishing will be completely free of charge during the beginning stages of the journal.
