Three new species of zoantharians described from coral reefs across the Indo-Pacific

One of them was named after the president of Palau, Tommy Remengesau, in honour of his and the nation’s support to the authors and marine conservation

Three new species of zoantharians were discovered by researchers from the University of the Ryukyus and Kagoshima University, Japan, and the Palau International Coral Reef Center. Despite not being previously known, all three species were found widely across the Indo-Pacific, with at least two species found in the Red Sea, the Maldives, Palau, and southern Japan.

Zoantharians, or colonial anemones, include species popular in the pet trade such as Zoanthus or Palythoa, but the new species are all much more cryptic, living in marine caves, cracks, or at depths below most recreational SCUBA diving (>20 m). The research was published December 29, 2017, in the open-access journal ZooKeys.

The three new species belong to the genus Antipathozoanthus, which contains species that only live on top of black coral colonies. However, surprisingly, one of the new species does not live on black corals, but instead in narrow cracks in coral reefs.

“We think that the new species, Antipathozoanthus obscurus, has evolved away from needing to be on top of black corals to take advantage of the available space in coral reef cracks”, said lead researcher Hiroki Kise.

“This is yet another example of how much diversity is right underneath our noses, but we still know nothing about it.”

Coral reefs, which are widely threatened by rising temperatures from global warming, are generally believed to harbour very high numbers of species, including yet many undescribed or unknown species.

Amongst the other two new species is Antipathozoanthus remengesaui, named after the current president of Palau, Tommy Remengesau.

“Much of our work was based in Palau”, said senior author Dr. James Reimer, “and we wished to acknowledge the fantastic support we have received from the nation. Palau is considered at the forefront of marine conservation, and much of this is thanks to President Remengesau’s vision.”

While the new discoveries shed more light on our understanding of coral reef biodiversity, this work is far from done. In fact, the researchers themselves estimate they still have up to ten more zoantharian species to describe from the waters of Palau and Okinawa.

“Marine diversity of coral reefs is amazing, with new surprises all the time”, said Kise, “and biodiversity scientists still have a lot more work to do.”

Evolutionary Systematics joins Pensoft’s portfolio of open access scholarly journals

Evolutionary Systematics is the latest authoritative journal to join the lines of the open access titles published on the Pensoft-developed technologically advanced journal publishing platform ARPHA.

Launched in 1884 and 1912, respectively, University of Hamburg’s journal Mitteilungen aus dem Hamburgischen Zoologischen Museum und Institut and Entomologische Mitteilungen are now resurrected under the name of Evolutionary Systematics.

Rebranded and refreshed, the journal has acquired a long list of technological user-friendly innovations, while simultaneously keeping its well-known expertise and devotion to whole-organism biology and collection-related research.

Its first issue in collaboration with Pensoft comprises two editorials dedicated to the extensive tradition and the bright future of the journal along with seven articles are already live on the journal’s new website.

Right underneath the new sleek look and feel welcoming users from the journal’s homepage, there are a lot of high-tech perks 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.

Furthermore, all publications are available in three formats (PDF, XML, HTML), complete with a whole set of semantic enhancements, so that the articles are easy to find, accessed and harvested by both humans and machines.

“We are happy to have joined forces with Lyubomir Penev and his professional team at Pensoft Publishers, once again now after having already successfully established together Zoosystematics and Evolution as an international journal of the Berlin Natural History Museum,” say editors Prof. Dr. Matthias Glaubrecht, Prof. Dr. Andreas Schmidt-Rhaesa and Dr. Martin Husemann.

“Certainly, I’m pleased to welcome Evolutionary Systematics to the family of Pensoft,” says the publisher’s founder and CEO Prof. Lyubomir Penev. “Combining our own solid experience in scholarly publishing with their amazing background, dating back to 19th century, will definitely benefit not only the two of us as collaborators, but all our present and future readers and users as well.”

Amongst the first papers, there is the description of the Bob Marley’s Intertidal Spider – a new arachnid species that emerged at low tide to the surprise of the research team of Drs. Barbara Baehr, Robert Raven and Danilo Harms. Once the scientists concluded it was a previously unknown species, they were quick to associate it with the reggae legend’s song “High Tide or Low Tide”.

The first issue also features the description of the Grey Wolf Spider – a common, yet enigmatic new species, which prompted the establishment of a new genus all to itself. The inaugural issue goes on to also announce as many as seven species of goblin spiders new to science . Their discovery results from a genus review involving a significant collection from the Otonga Nature Reserve, Ecuador.

New species of marine spider emerges at low tide to remind scientists of Bob Marley

It was 02:00h on 11 January 2009 when the sea along the coastline of Australia’s “Sunshine State” of Queensland receded to such an extent that it exposed a population of water-adapted spiders. The observant researchers who would later describe these spiders as a species new to science, were quick to associate their emergence with reggae legend Bob Marley and his song “High Tide or Low Tide”.

In their paper, published in the open access journal Evolutionary Systematics, the team of Drs. Barbara Baehr, Robert Raven and Danilo Harms, affiliated with Queensland Museum and the University of Hamburg, describe the new Bob Marley’s intertidal spider and also provide new information on two of its previously known, yet understudied, relatives from Samoa and Western Australia.

Unlike the spiders which people are familiar with, the intertidal species, whose representative is Bob Marley’s namesake, are truly marine. They have adapted to the underwater life by hiding in barnacle shells, corals or kelp holdfast during high tide. To breathe, they build air chambers from silk. Once the sea water recedes, though, they are out and about hunting small invertebrates that roam the surfaces of the nearby rocks, corals and plants.

The new species, listed under the scientific name of Desis bobmarleyi, is described based on male and female specimens spotted and collected from brain coral on that night in January.

Both sexes are characterised by predominantly red-brown colours, while their legs are orange-brown and covered with a dense layer of long, thin and dark grey hair-like structures. The females appear to be larger in size with the studied specimen measuring nearly 9 mm, whereas the male was about 6 mm long.

While the exact distribution range of the newly described species remains unknown, it is currently recorded from the intertidal zones of the Great Barrier Reef on the north-eastern coast of Queensland.

“The song ‘High Tide or Low Tide’ promotes love and friendship through all struggles of life,” explain the authors for their curious choice of a name. “It is his music that aided a field trip to Port Douglas in coastal Queensland, Australia, to collect spiders with a highly unique biology.”

Apart from reporting their research, the scientists use their paper to pay tribute to a German naturalist from the late 19th century – Amalie Dietrich, as well as the famous Jamaican singer and songwriter. Both admirable figures, even if representative of very different fields, are seen by the authors as examples of “the adventurous and resilient at heart” human nature in pursuit of freedom and independence.

Citizen scientists discover 6 new species of beetles in Borneo

Scientists estimate that 80% of the world’s animal and plant species are still unknown. Although the work of taxonomists (whose job is to describe and name those) is appreciated by the general public, funding for taxonomy is dwindling. Moreover, while the areas hosting most of the unknown biodiversity are under threat, time is running out.

To help solve this problem, Taxon Expeditions has become the first organisation in the world to initiate field courses for citizen scientists in biodiversity hotspots, with the aim of discovering, describing, naming, and publishing new species under the slogan “You can be Darwin too”.

“Relying on extra hands means that unknown species can be discovered faster and,” says Taxon Expeditions director and biologist Dr. Iva Njunjic, “for some of that work, you don’t even need to be a trained taxonomist.”

Taxon Expedition’s first field course to the remote 30-kilometre-wide Maliau Basin in Malaysian Borneo, yielded six new species. Three of those, all tiny beetles living in rainforest leaf litter, are published today in the Biodiversity Data Journal. The other three, belonging to the family Elmidae (riffle beetles) will be published next year.

Citizen scientists discovered these species during a field exercise employing the method of ‘Winkler extraction’. Using this technique, dead leaves are collected from the rainforest floor before being sieved, so that hundreds of tiny soil-dwelling insects can be revealed.

Professor Menno Schilthuizen recognised three of those as new species. Under his guidance, the participants studied, photographed and drew the specimens in the expedition’s field lab, extracted their DNA and finalised a draft ready for publication.

The participants also came up with the original names for the three new species. English teacher Sean Otani from Japan decided to name Colenisia chungi after Malaysian entomologist Arthur Chung. The names for Clavicornaltica sabahensis and Dermatohomoeus maliauensis referring to the studied sites were suggested by staff and rangers of Maliau Conservation Area during the farewell party for the course.

All collected samples are deposited in the insect collection of Universiti Malaysia Sabah and the rest of the results – in online databases. This way, these discoveries will help other biologists working on Borneo’s biodiversity.

In March 2018, Taxon Expeditions will again head for Maliau Basin with a new group of participants, hopefully discovering more new species for science. Meanwhile, this year’s team look back on having contributed to real scientific discoveries.

“I had no idea how different, how exciting, how interesting it was going to be. It has been an amazing experience,” says retired corporate account manager Mary Erickson from Canada.

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 Botany, Data 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.

*Smithsonian researchers classifying digitized herbarium sheets.*

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.

*Sample herbarium specimen image of stained clubmoss.*

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.

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.

Heat-loving Australian ants believe in diversity, hint 74 species new to science

The ‘furnace ants’ or ‘honeypot ants’ present a very large genus of ants, Melophorus, confined to Australia. Long believed to be megadiverse, some scientists have even suggested that the group may contain ‘well over 1000 species’. However, to this point, only 32 species and subspecies had been described.

Scientists Dr Brian Heterick of Curtin University, Dr Mark Castalanelli of Ecodiagnostics Pty Ltd and Dr Steve Shattuck of the Australian National University, funded by an internationally competitive Australian Biological Resources (ABRS) grant, set out to find the true facts.

As a result, they discovered as many as 74 new species belonging to Melophorus. In their study, published in the open access journal ZooKeys, they also provide a taxonomic key to the workers of a total of 93 species in the genus.

Among the studied ants, there are quite bizarre ones, including a species (Melophorus hirsutus) whose eyes are strangely protruding out of his head to a varying degree. In the extreme cases, the eyes are so pointy that could be likened to ice-cream cones. Named many years ago, this ant appears to be older than the rest of the examined living species. Furthermore, unlike most of them, it does not seem adapted to heat. It is confined to the wet eastern coast of Australia.

Dr Heterick spent two weeks collecting specimens in the often rugged and forbidding terrain of Western Australia, while the team also asked a number of major museum collections to loan them specimens.

The newly collected ants were placed in alcohol and subjected to genetic tests using one mitochondrial and four nuclear genes. The findings were then compared with those from physical examinations to prepare the taxonomic key – a set of distinctive features per species that can be used to differentiate within the group.

Given the generally complex nature of these ants, the authors expect for the genus to further expand in future. They speculate that even though the numbers may increase to around 100 species, not the ‘well over 1000’ previously predicted, they still illustrate an incredible diversity.

The authors estimate that Melophorus arose around 35 million years ago. The closest relatives of the genus are also confined to the Australasian region with the exception of a single genus living in South America.

Furthermore, the genus is also quite astonishing thanks to another trait shared among the species.

“By the way, this group of ants has a thing or two to tell those of us who get lost easily!” comments lead author Dr Brian Heterick.

“They can find their way home in a featureless landscape by means of an internal compass influenced by information gathered on earlier journeys. We are not the first species to use a computing system!”

Six new sponge species and new symbiotic associations from the Indonesian coral triangle

Comprising more than 17,000 islands, the Indonesian archipelago is one of the world’s most biodiverse places on Earth.

Sponges, aquatic organisms whose bodies consist of numerous pores to allow the ingress of water, are key components of this richness and play a fundamental role in the survival of coral reef habitats. Furthermore, they are also known for their medicinal benefits.

Unfortunately, due to the paucity of taxonomic expertise, the sponges from the Indonesian reefs are often ignored in monitoring surveys and conservation programmes, while their diversity is largely underestimated.

Researchers from the Italian Università Politecnica delle Marche and Università degli Studi di Genova, PharmaMar, Spain, and University of Sam Ratulangi, Indonesia, describe six new species in their paper in the open access journal, ZooKeys.

Inspired by their extraordinary biodiversity, the researchers teamed up with the pharmaceutical company PharmaMar to conduct several expeditions in the waters of North Sulawesi Island.

The authors reported a total of 94 demosponge species belonging to 33 families living in the North Sulawesi Island. Amongst them, there are six species new to science and two previously unknown symbiotic relationships.

Seven of the recorded species were collected for the very first time since their original description.

However, these findings are still scarce, given the abundance of the sponges in similar localities in the Indonesian archipelago.

In conclusion, the authors note that the marine diversity in Indonesia is still far from being well known.

“Thanks to this impressive diversity, these areas are important spots for diving tourism and require the urgent development of sustainable tourism practices,” they say.

Threatened Alabama snail renamed after a case of mistaken identity

Contrary to what scientists have known for over 100 years, the Painted Rocksnail turns out to have never existed outside the Coosa River system

Alabama has some of the highest diversity of freshwater snails in the world, but many snails are at high risk of extinction.

An essential part of determining extinction risk is knowing the range of a given species and determining how much its range has contracted owing to anthropogenic impacts, but mistaken identity or misidentification can complicate conservation efforts.

The Painted Rocksnail, a small snail from the Coosa River system, has been mistakenly identified as other species for over 100 years.

In a study published in the open access journal ZooKeys, scientists Dr. Nathan Whelan, U.S. Fish and Wildlife Service, Dr. Paul Johnson and Jeff Garner, Alabama Department of Conservation and Natural Resources, and Dr. Ellen Strong, Smithsonian Institution National Museum of Natural History, tackled the identity of the Painted Rocksnail, a small federally threatened species native to the Mobile River basin in Alabama.

Freshwater snails are notoriously difficult to identify, as the shells of many species can look very similar. Keeping this in mind, the researchers began to notice that many shells identified as the Painted Rocksnail in museums around the world were misidentified specimens of the Spotted Rocksnail, another snail species found in Alabama.

After examining shells at the Academy of Natural Sciences of Philadelphia, Museum of Comparative Zoology at Harvard, National Museum of Natural History, North Carolina Museum of Natural Sciences, Florida Museum of Natural History, and Natural History Museum in London, in addition to hundreds of hours of their own sampling throughout the Mobile River basin, the authors determined that all previous reports of the Painted Rocksnail from outside the Coosa River system were mistakes.

Despite the Painted Rocksnail dwelling in well-studied rivers near large population centers, mistaken identity of the species has persisted almost since the species was described back in 1861 by Isaac Lea.

Only after careful examination of shells collected in the last 150 years and analyses of live animals were the researchers able to confidently determine that the Painted Rocksnail never occurred outside the Coosa River system.

The study has implications for the conservation of the Painted Rocksnail, as the species was historically more restricted than previously thought. Recent surveys by the authors only found the species in small stretches of the Coosa River, Choccolocco Creek, Buxahatchee Creek, and Ohatchee Creek.

In conclusion, the authors note the importance of natural history museums and the importance of studying snails in the southeastern United States.

“Without the shells stored in natural history museums we would have never been able to determine that the supposed historical range of the Painted Rocksnail was incorrect, which could have resulted in less effective conservation efforts for an animal that is very important to the health of rivers in Alabama,” they say.
