Scent of a coral: Symbiosis between 2 new barnacle species and a gorgonian host

Two new species of the gorgonian inhabiting barnacles — Conopea saotomensis and Conopea fidelis — have been collected from the area surrounding the historically isolated volcanic islands of São Tomé and Príncipe. The barnacles of this genus are widely spread across the temperate and tropical oceans, but what makes them special is that they occur exclusively in a symbiotic relationship with a gorgonian or black coral hosts. Observations suggest that the barnacles might have a unique ability to recognize and choose a specific host of their preference. The study was published in the open access, peer-reviewed journal ZooKeys.

The islands near which the two new species of Conopea were found are the products of large shield volcanoes originating 3,000 m below the ocean’s surface along the Cameroon line. São Tomé and Príncipe are particularly old islands, 13 and 30 millions of years old, respectively, and form part of the Gulf of Guinea island chain known for its remarkable natural beauty. The islands are home to a large number of endemic birds and plants such as the world’s smallest ibis, the São Tomé Ibis, and the world’s largest sunbird, the Giant Sunbird. Being of volcanic origin and 274 km west of northern Gabon, the islands have never been connected to the African mainland. Such a historical isolation of the area where the new species are found suggests the possibility of endemism.

The newly discovered barnacles are both gorgonian inhabiting. Observations by the authors suggest that they also demonstrate preference to a particular gorgonian hosts. This peculiar behavior is reflected in the name of one of the newly described species, Conopea fideli, referring to the ‘fidelity’ of the barnacle towards its host of preference. The host gorgonians are a particular type of beautiful octocoral, also known as sea fans. Once locating the host, the barnacle then lives in complete symbiosis with the gorgonian, almost fully covered by host tissue.

To date, not all the details of barnacle larvae settlement and interaction with the gorgonian host are known, but it seems that barnacle larvae are able to choose between the different gorgonians in their search for a host. This rather high degree of symbiotic relationship, almost like a love story, is believed to be mediated by pheromones. It has been demonstrated that barnacle larvae can determine where to settle by recognizing pheromone cues from their host. It has also been shown that gorgonians produce barnacle settlement inducers as well as inhibitors.

The lead author of the article, Dana Carrison-Stone from the Department of Invertebrate Zoology and Geology, California Academy of Sciences, comments: "Although the details of the settling barnacle larvae and gorgonian interaction are not completely known, it appears, from our observations (specifically that Conopea fidelis was found only on Muriceopsis tuberculata) that barnacle larvae may be capable of distinguishing between gorgonian species. Of course, more collections, identifications, and laboratory work testing settlement preference would be needed to answer this question."

4 new species of water-gliding rove beetles discovered in Ningxia, China

Four new species from the Steninae subfamily of the large family of rove beetles (Staphylinidae) have been discovered in the Ningxia Autonomous Region, China, as part of an exploration of the insect fauna of the Liupan Shan Natural Reserve, where a large number of specimens has been collected. The expedition also yielded 11 new records for the Ningxia province of previously described Steninae species. The study was published in the open access, peer reviewed journal Zookeys.

The Ningxia Autonomous Region is mainly known as a dry, desert-like land. The region of the Liupan Shan Natural Reserve, however, is part of the Liupan Shan mountains, also known as the green pearl on the Loess Plateau. The area is also regarded as a "Kingdom of Animals" for its great biological diversity.

The rove beetle family, Staphylinidae, is one of the most widely distributed beetle families in the world. However, the representatives of the Steninae subfamily are of particular interest. These fascinating beetles are known for their unique ability to glide on the surface of water.This special skill is made possible through evolutionary adjustment allowing the production of special gland secretions that reduce surface tension.

Out of the four newly described species two are from the genus Dianous, and as all representatives are experts in water gliding. The other two belong to the genus Stenus where this ability is only partly present. One of the species, Stenus liupanshanus lives in leaf litter and is therefore believed to not demonstrate the ability. However the other one, Stenus biwenxuani, was found on shore and is therefore considered to be a water glider.

Steninae are also specialist predators of small invertebrates such as collembola, which are frequently found in leaf litter. What is fascinating is the special hunting technique used by those beetles to catch their prey. Species in the genus Stenus can eject some of its mouth parts using blood pressure. The thin rod of the labium ends in a pair of pads with bristly hairs and hooks, called paraglossa, and between these hairs are small pores that exude an adhesive glue-like substance, which sticks to prey to secure a perfect catch and no escape.

Dr. Liang Tang from the Department of Biology, Shanghai Normal University, comments: "As far as the Steninae are concerned, Ningxia Autonomous Region is one of the most poorly explored regions, with merely two species being recorded until 2008. In the summer of 2008, a team surveyed the insect fauna of the Liupan Shan in southern Ningxia and collected a large number of Steninae. In this paper, we report the results of the study, which includes two new Stenus and two new Dianous species, and new province records for eleven Stenus species."

Little did we know about beetle diversity: Astonishing 138 new species in a single genus

The tropics are home to an extraordinary diversity of insect species. How great is it, exactly? We do not know, but today, researchers at the Santa Barbara Museum of Natural History published a study on tropical beetles that can help us progress towards an answer to this question. The paper was published in the open access, peer-reviewed journal Zookeys.

Entomologists Michael Caterino and Alexey Tishechkin have named 138 new species within the genus Operclipygus (the name refers to their clamshell-like rear end), thereby increasing the size of the genus over six times. The work is based on a study of over 4000 specimens amassed from natural history museums all over the World, as well as specimens from fieldwork collected throughout Central and South America by the authors.

The lead co-author of the paper, Dr. Caterino, comments of on the significance of such biodiversity: ‘We all know that forests in the tropics are disappearing. But we only have the faintest idea of how much biodiversity is disappearing with them. Studies like this are critical to seeing where the greatest diversity is, and finding out the best ways to protect it’,

These beetles all belong to a family known as histerids, or ‘clown beetles’. All of the newly described species are similar in appearance to a poppy seed – small, round and black. Because of their extreme abundance, however, they have an ecological importance disproportionate to their size. As voracious predators of other insects’ larvae, these beetles help controlling pestiferous flies. As in some cases their menu includes fly larvae found in decomposing bodies, some researchers have been promoting their use in forensic investigations.

Since the days of Darwin, Wallace, and Bates, entomologists have both celebrated and bemoaned the overwhelming diversity of tropical insects. Modern-day scientists continue to grapple with the question of just what extent of insect biodiversity lives in the tropical parts of the World, with estimates ranging from 5 to 30 million species or more. This study is only one part of a larger revision of several related histerid genera, and it seems not to be an isolated case, with most groups revealing 5 to 6 times the species currently documented.

So while biologists have a long way to go in fully documenting the species diversity in rapidly-disappearing tropical forests, comprehensive taxonomic revisions of neglected insect groups can help to clarify the magnitude of what’s at stake. This project was funded by the Advancing Revisionary Taxonomy and Systematics program of the U.S. National Science Foundation, and it clearly demonstrates what dedicated support for taxonomy can do for our understanding of global biodiversity.
Dr. Caterino closes: ‘We’re committed to doing our best to let people know what’s out there before it’s too late’.

Data paper describes Antarctic biodiversity data gathered by 90 expeditions since 1956

Huge data encompassed into a unique georeferenced macrobenthic assemblages database

A new peer-reviewed data paper offers a comprehensive, open-access collection of georeferenced biological information about the Antarctic macrobenthic communities. The term macrobenthic refers to the visible-for-the-eye organisms that live near or on the sea bottom such as echinoderms, sponges, ascidians, crustaceans. The paper will help in coordinating biodiversity research and conservation activities on species living near the ocean bottom of the Antarctic.

The data paper "Antarctic macrobenthic communities: A compilation of circumpolar information", published in the open access journal Nature Conservation, describes data from approximately 90 different expeditions in the region since 1956 that have now been made openly available under a CC-By license. The paper provides unique georeferenced biological basic information for the planning of future coordinated research activities, for example those under the umbrella of the biology program Antarctic Thresholds – Ecosystem Resilience and Adaptation (AnT-ERA) of the Scientific Committee on Antarctic Research (SCAR). The information collected could be also beneficial for current conservation priorities such as the planning of Marine Protected Areas (MPAs) by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

The expeditions were organised by several famous explorers of the Antarctic. The area covered by the paper consists of almost the entire Southern Ocean, including sites covered by a single ice-shelf. The vast majority of information is from shelf areas around the continent at water depth shallower than 800m. The information from the different sources is then attributed to the classified macrobenthic assemblages. The results are made publicly available via the "Antarctic Biodiversity Facility" (data.biodiversity.aq).

A specific feature of this paper is that the manuscript was automatically generated from the Integrated Publishing Toolkit of the Antarctic Node of the Global Biodiversity Information Facility (AntaBIF IPT) and then submitted to the journal Nature Conservation through a novel workflow developed by GBIF and Pensoft Publishers. (see previous press release). Data are made freely available through the AntaBIF IPT, and sea-bed images of 214 localities through the data repository for geoscience and environmental data, PANGAEA- Data Publisher for Earth and Environmental Science (sample: http://doi.pangaea.de/10.1594/PANGAEA.198682).

Speaking from on board the research vessel ‘Polarstern’, the paper’s lead author Prof. Julian Gutt of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, Germany commented:

"The most important achievement of this paper is that data collected over many years and by various institutions are now not only freely available for anyone to download and use, but also properly described to facilitate future work in re-using the data. The Data Paper concept is certainly a great approach that multiplies the effect of funds and efforts spent by generations of scientists."

The data will also be used for a comprehensive Biogeography Atlas of the Southern Ocean project to be released during the XI SCAR Biology Symposium in Barcelona July 2013.

What is a Data Paper?

A Data Paper is a scholarly journal publication whose primary purpose is to describe a dataset or a group of datasets, rather than to report a research investigation. As such, it contains facts about data, not hypotheses and arguments in support of those hypotheses based upon data, as found in a conventional research article. Its purposes are three-fold:

to provide a citable journal publication that brings scholarly credit to data publishers;
to describe the data in a structured human-readable form;
to bring the existence of the data to the attention of the scholarly community.

New scorpion discovery near metropolitan Tucson, Arizona

A new species of scorpion, Vaejovis brysoni, was found in the Santa Catalina Mountains in southern Arizona. Another scorpion of the same group also inhabits this mountain range, making this the first documented case of two vorhiesi group species distributed on the same mountain. The study was published in the open access, peer-reviewed journal Zookeys.

These mountains overlook the city of Tucson, Arizona. Amazingly, in the 21st century, there are still new species to be discovered right here in the United States. What is even more surprising is that the new species was found within sight of a large metropolitan area.

Recently Dr. Rob Bryson Jr. discovered this new species while looking for a completely different animal. Many important discoveries are made this way by scientists who start out working on something completely different. He sent specimens to the authors, who determined that they were indeed a new scorpion species. At that point, the team was assembled and the rest is history.

For over 50 years only four species of mountain scorpions were known from the state of Arizona. That number has more than doubled over the past six years, with a total of 10 species now known, all belonging to the same group. Arizona is known for isolated mountain habitats in the desert known as Sky Islands. These Sky Islands are where the new species are being discovered.
"This latest new scorpion is a prime example of the amazing diversity of life still to be discovered, right here in 21st century America.", adds Richard F. Ayrey, one of the co-author of the original article.

Spectacular forcepfly species discovered for the first time in South America

Forcepflies are usually known as earwigflies, because the males have a large genital forceps that resembles the cerci of earwigs. A new species of forcepfly Meropeidae (Mecoptera) from Brazil was described, representing only the 3rd extant species described in this family and the 1st record of the family from the Neotropical region. The distribution and biogeography of the family are discussed and it is even proposed that Meropeidae originated before continental drift and then divided into two branches, northern and southern, with the breakup of the old supercontinent Pangea. The study was published in the open access journal ZooKeys.

Despite all previous collecting efforts in this area the species had never been recorded before. The specimen was collected in a private ranch near a forest fragment surrounded by farms in the Atlantic Forest biome, one of the most threatened in Brazil. It can be found in a variety of habitats, including woodland, Jarrah forest, and sand plain vegetation. What makes forcepflies special is the fact that little is known about their biology and the immature stages remain a mystery to scientists. The adults, who are nocturnal and seem to live on the ground, are also capable of stridulation, or the production of sound by rubbing certain body parts.

"The discovery of this new relict species is an important signal to reinforce the conservation of Brazilian Atlantic Forest biome. Certainly there are many more mecopterans species yet to be discovered in these forests", said the lead author Dr Renato Machado from the Texas A & M University, College Station, USA.

Thailand: Astonishing 10 new species of semi-aquatic freshwater earthworms revealed

The newly described species might benefit the development of organic rice farming

The semi-aquatic earthworms in the genus Glyphidrilus are somewhat unfamiliar species that live between the terrestrial and freshwater ecosystems of rivers, streams, canals, ponds, swamps and paddy systems. Remarkably, each species is endemic to a single water basin, carrying its own signature of evolution from their common origin. A study describing ten newly discovered species of the genus has been published in the open access journal ZooKeys.

In Thailand, the species demonstrate astonishing biodiversity due to the monsoon climate contributing to drastic river system changes and a large variety of microhabitats. While general interconnections among these allow for gene flow, their great diversity leads to independent evolution and specialization in isolation.

The animals orient themselves vertically, with their bodies in the wet soil along the banks and tails placed on the soil surface. Among the interesting characteristics of these worms is a rounded body tip, while the end is square shaped. When twisted, the posterior end, which is normally above the soil surface, forms U-shaped channels. These are used to allow water circulation down the burrow. This is probably an evolutionary adjustments that ensures oxygen transport to the deeper surface of the worms, while their bodies remain in the burrows.

Another peculiar feature are the so-called "wings", or the expanded part of epidermis near the body tip. The function of the wings is still unknown to scientists, but it has been suggested that they evolved to assist breathing in such aquatic habitats. Because the wings will be located deep in the burrow at a low oxygen supply and are absent in sexually immature juveniles, a more conventional explanation might be that they are used to aid copulation rather than respiration.

Among the natural habitats of these worms are the rice fields in Thailand, which serve as a reservoir and breeding ground for the animals. The worms turn out to play an important role in the development of rice farming, being a facilitator in the decomposition of organic matter to be a natural fertilizer, as well as improving the soil properties for better rice root system. The species also assist the release of essential minerals in some chemical fertilizers, though not in pesticides, which prove to be lethal to the worms.

The increased use of pesticides in agriculture puts these species in danger. The author Dr. Somsak Panha, from the Animal Systematics Research Unit, Chulalongkorn University in Bangkok, Thailand, comments: "The worms will survive in areas using chemical fertilizers but not those using chemical pesticides. However, the worms did well in areas of organic farming and so are likely to be sensitive to modern agrochemical contamination of the environment. They may play an important role in organic rice farming."
