New fanged dwarf dinosaur from southern Africa ate plants

The single specimen of the new species was originally chipped out of red rock in southern Africa in the 1960’s and discovered in a collection of fossils at Harvard University by National Geographic Explorer-in-Residence Paul Sereno, paleontologist and professor at the University of Chicago. Details of the dinosaur’s anatomy and lifestyle are part of a monograph by Sereno dedicated to these puny herbivores and published in the online journal ZooKeys and on the website of the National Geographic Society.

Named Pegomastax africanus, or "thick jaw from Africa", the new species has a short parrot-shaped beak up front, a pair of stabbing canines, and tall teeth tucked behind for slicing plants. The tall teeth in upper and lower jaws operated like self-sharpening scissors, with shearing wear facets that slid past one another when the jaws closed. The parrot-shaped skull, less than three inches long, may have been adapted to plucking fruit.

"Very rare", admits Sereno, "that a plant-eater like Pegomastax would sport sharp-edged, enlarged canines" like that of a vampire. Some scientists have argued that consuming meat or at the least insects was a good part of the diet of heterodontosaurs, which evolved near the root of the great bird-hipped radiation of dinosaurs that includes the famous plant-eaters Triceratops and Stegosaurus.

Self-defense and competitive sparring for mates is more likely their role, argues Sereno in the study, based on microscopic examination of the teeth of Pegomastax and kin. Wear facets and chipped enamel suggest that the fangs of Pegomastax and other heterodontosaurs were used like those of living fanged deer for nipping or even digging rather than slicing flesh.

A bizarre covering of bristles, something like that of a porcupine, likely covered most of the body of Pegomastax, which measured less than two-feet in length and weighed less than a housecat. These bristles first came to light in a similar-sized heterodontosaur, Tianyulong, discovered recently in China and described in the study. Buried in lake sediment and covered by volcanic ash, Tianyulong preserves hundreds of bristles spread across its body from its neck to the tip of its tail. In life, dwarf-sized heterodontosaurs like Pegomastax would have scampered around in search of suitable plants, says Sereno, looking something like a "nimble two-legged porcupine".

When Pegomastax lived some 200 million years ago, the supercontinent Pangaea had just begun to split into northern and southern landmasses. Heterodontosaurs appear to have divided similarly, the study argues, the northern species with simple triangular teeth like Tianyulong and the southern species with taller crowns like Pegomastax.

Sereno marvels at these punk-sized early herbivores that spread across the globe. Although virtually unknown to the public, "Pegomastax and kin were the most advanced plant-eaters of their day".

ZooKeys’ Statement on electronic publishing, ZooBank registration and printed version


In respond to several inquiries and in the light of the current lively discussions on Taxacom and in some blogs, ZooKeys considered necessary to publish the following statement:

1. ZooKeys was the first – and still is – the only journal that registers authors, publications and new names in ZooBank. We have been doing this for our authors since July 2008, when the first ZooKeys issue was published. We shall continue this practice and ZooKeys’ authors will not need to bother with any kind of registration issues to make their taxa validly published.

2. ZooKeys articles are archived in two global archives: (1) PubMedCentral based in the National Library of Medicine of the U.S. All content in PubMedCentral is available in open access, the separate taxa descriptions (treatments) are highlighted with separate links, and in addition, the PDF version and each image file are archived separately; (2) CLOCKSS, which is an international, not for profit, joint venture between the world’s leading scholarly publishers and research libraries initiated by Stanford University. Again, the authors do not need to worry personally about archiving!

3. According to our policies, anyone – a private person or institution – can download, archive, print and distribute the full content of ZooKeys. This is probably the best add-on archiving policy one may think about, because downloads of individual articles are counted in several hundreds, to say the least.

4. ZooKeys will continue to print its full-color, high-resolution version, which is available in several libraries, such as Smithsonian, Harvard, Naturalis (Leiden), the Dutch Entomological Society’s library, and some more. Separate printed issues or reprints are available on purchase. 

5. ZooKeys will continue to export taxon descriptions (treatments) to Encyclopedia of Life, Plazi Treatment Repository and Species-ID.net – a Wiki based treatment repository. Naturally, treatments are available in open access for anyone to read and the original publications are linked back from there.

6. Each individual ZooKeys article is published electronically as soon as the final proof is approved by the author; the date of publishing of the electronic version should be considered the valid date of publication of the article. Paper version will be published when an issue is completed. This will greatly facilitate the efficiency and speed of publication, without having any adverse effect on archiving and/or distribution!

7. ZooKeys will continue to assist authors in data publishing and archiving through GBIF (occurrence data) and DRYAD Data Repository (any other data).

8. ZooKeys will continue to assist authors in drafting and dissemination of press releases and other materials that promote their research.

9. These policies will be followed also by the other zoological journals published by Pensoft, such as Journal of Hymenoptera Research, International Journal of Myriapodology, and Comparative Cytogenetics.  
 

Wild bees: Champions for food security and protecting our biodiversity

Pollinating insects contribute to agricultural production in 150 (84%) European crops. These crops depend partly or entirely upon insects for their pollination and yield. The value of insect pollinators is estimated to be €22 billion a year in Europe. Declines in managed pollinators, such as honeybees, and wild pollinator such bumblebees, solitary bees and hoverflies, are therefore of growing concern as we need to protect food production and the maintain wildflower diversity.

Scientists involved in STEP, a large-scale project funded by the 7th Framework Program (FP7) of the European Union, have therefore taken an inclusive approach looking at the status and trends of all Europe’s pollinators.

New findings have been presented at a dedicated STEP symposium at the 5th EurBee meeting held in Halle, Germany on 3-6 September 2012. Prof Simon Potts from the University of Reading, UK and coordinator of STEP opened the discussion: "To help Europe secure sustainable food production and conserve its biodiversity we need to provide policy makers with clear evidence of who pollinates our crops and flowers and what are the best options to safeguard pollination services in a changing world".

More than 32 million European records of pollinators and plants have been analysed. "We have shown that not only has bee diversity been declining but communities are becoming more uniform in their composition", commented the lead scientist Dr Koos Beismeijer from Netherlands Centre for Biodiversity Naturalis, The Netherlands.

One key threat to bees is agrochemicals; "we are now finding strong negative effects of pesticides, not only in honeybees and bumblebees, but also solitary bees– as Europe has more than 2,500 solitary bee species we expect the implications of our research to be very wide ranging" said Dr Christoph Sandrock of Swiss Bee Research Centre.

Many European countries have an array of agri-environment options aiming to support biodiversity, including bees, but it is unclear how effective these really are. "Our analysis is the first to systematically test whether agri-environment options are actually benefiting bees" said Dr David Kleijn from Alterra, Netherlands.

Several European countries have programmes aiming to improve honeybee health, but there is very little support for wild pollinators despite their critical roles in ecosystems. "One of the big achievements of the STEP project will be the first ever European Red List for bees which will provide an essential tool for politicians and land managers to direct conservation efforts targeted at wild bees" said Mr Stuart Roberts from University of Reading, UK.

"There is increasing evidence that honeybee numbers are insufficient in many parts of Europe to provide adequate pollination services, and so wild pollinators are needed to cover the shortfall" stated Dr Tom Breeze from University of Reading, UK.

The STEP project will continue to use high quality research to deliver the evidence politicians need to develop better policies to protect all of Europe’s pollinators. The project also uses its findings to develop specialist factsheets targeted at groups such as farmers and translated in 15 languages: see http://step-project.net/page.php?P=4&SP=14

Simultaneously, STEP is undertaking a broad-scale survey of the public opinion through online questionnaires available in seven European languages. The survey aims to reveal if, and to what extent, people are aware of the role of pollinators in agricultural ecosystems and the consequences for the environment from the decline of bees and other insect pollinators. Please spend 5 minutes of your time and fill it in at: http://www.step-project.net/page.php?P=26

DNA sequences need quality time too – guidelines for quality control published

 Like all sources of information, DNA sequences come in various degrees of quality and reliability. To identify, proof, and discard compromised molecular data has thus become a critical component of the scientific endeavor – one that everyone generating sequence data is assumed to carry out before using the sequences for research purposes.

"Many researchers find sequence quality control difficult, though", says Dr. Henrik Nilsson of the University of Gothenburg and the lead author of a new article on sequence reliability, published in the Open Access journal MycoKeys. "There just isn’t any straightforward document to put in their hands to give them a flying start. As a result, scientists differ in the degree to which they are aware of the need to exercise sequence quality control and in what measures they take." Previous studies have highlighted several shortcomings of publicly available DNA sequences – more than ten percent of the fungal DNA sequences may be misidentified at the species level, for example.

"A second complication", adds co-author Prof. Urmas Koljalg of the University of Tartu, "is that the software available for sequence quality management tend to be very complex and resource intensive. It borders on the unfair to expect everyone to have access to, and to master, such computer environments. Fortunately, a whole lot can be done towards quality control of DNA sequences using just manual means and a web browser. The current MycoKeys paper describes these means to help those biologists who do not have a strong background in computer science."

The article – "Five simple guidelines for establishing basic authenticity and reliability of newly generated fungal ITS sequences" – compiles principles and observations to assist the reader in the quality management of sequence data. Although focusing on fungi, the guidelines are general and apply to most groups of organisms and genes. The guidelines target traditional DNA sequencing and are broadly applicable to datasets used in systematics, taxonomy, and ecology.

Co-author Dr. Martin Hartmann of the Swiss Federal Research Institute WSL concludes, "We hope that our guidelines will assist the readers in sharpening their datasets so that, eventually, the trend of increasing noise in the public sequence databases can be arrested. Molecular data offer so much promise that we simply cannot afford to lose accuracy to bias and artifacts."

Zoologists are no longer restricted to publish new species on paper

Electronic publishing of new animal species allowed by new rules of the International Code of Zoological  Nomenclature (ICZN)

In a highly debated decision, the rules for publication of scientific zoological names have changed to allow purely digital publications to meet the requirements of the stringent Code of Zoological Nomenclature. On 4th of September, the International Commission on Zoological Nomenclature (ICZN) has passed an amendment that considers a publication in a digital scientific journal ‘legitimate’ if meeting archiving criteria and the publication is registered at the ICZN’s official online registry, ZooBank. The Amendment was published simultaneously in the journals ZooKeys and Zootaxa.

The decision has been contentious because the rules of the ICZN are considered to be among the most rigorous in scientific publication. The task of keeping information straight on animal names is immense and critical, as almost all data on the living world is linked through organismal names. Animals comprise the vast majority of multicellular species recognised (currently around 1.8 million, growing at a rate of about 20,000/year) and for each of these taxa, there are as many as 2-10 legitimately published names due to past debate and poor information exchange. Estimates of the total of living animal biodiversity are 4-20 times this number (8-50 million species).

The change in ICZN publication rules is intended to speed the process of publishing biodiversity information, to improve access to this information, and to help reduce the ‘taxonomic impediment’ that hinders cataloguing of the living world. The move, however, is seen by some as a risky experiment in unmooring a previously well-anchored system of linking publications, names and taxonomic concepts.

The ICZN ruling is explicit that while the publication can exist in an electronic-only format, it still must be published through a journal or book that has an ISSN or ISBN (International Standard Serial Number or International Standard Book Number) and should indicate that it will be archived for long term access. Purely web options such as blog posts, forums, Wikimedia, Wikipedia, Scratchpads and other potentially ephemeral, unarchived web-only sources still do not qualify as legitimate publications under the new ICZN rules.

In practical terms this means:

1) The work must be registered in ZooBank prior to publication
2) The work itself states the date of publication and includes the registration record number (LSID) at ZooBank
3) The ZooBank registration record contains the ISSN or ISBN of the piblication venue (journal or book0  and the name of an electronic archive where the work is intended to be preserved

“The change in ICZN publication rules is intended to speed the process of publishing biodiversity information, to improve access to this information, and to help reduce the ‘taxonomic impediment’ that hinders our cataloguing of the living world. The new rules will open the door to electronic publication and facilitate a truly web-based taxonomy!”, said Dr Ellinor Mitchel, Executive Secretary of ICZN.

Bees that go ‘Cuckoo’ in others’ nests

5 new species of cuckoo bees from the Cape Verde Islands

The biota of island archipelagos is of considerable interest to biologists. These isolated areas often act as ‘evolutionary laboratories’, spawning biological diversity rapidly and permitting many mechanisms to be observed and studied over relatively short periods of time. Such islands are often the places of new discoveries, including the documentation of new species.

The Republic of Cape Verde comprises 10 inhabited islands about 570 kilometers off the coast of West Africa and have been known since at least 1456. Although the bee fauna of the islands was thought to be moderately well known, research by Dr. Jakub Straka of Charles University in Prague and Dr. Michael S. Engel of the University of Kansas have shown that this is not the case. A recent study published in the Open Access journal ZooKeys documents the cuckoo bee fauna of the islands, revealing that their entire fauna of cuckoo bee species is in fact new to science.

These bees, like the more widely known cuckoo birds, invade the nests of other host bee species. While the host is out collecting pollen for its brood, the cuckoo bee female enters the nest and deposits her eggs on the food resource. The cuckoo bee egg hatches and the immature promptly dispatches the host egg, leaving the pollen and nectar reserves for itself.

The Cape Verde cuckoos are mostly large, black-and-white species, almost zebra-like in their appearance. However, one species, Chiasmognathus batelkai, is quite small, merely 3.2 – 4.2 millimeters in length. Despite its small proportions, C. batelkai is still the largest species of its genus, a group which otherwise comprises even more diminutive species. It appears as though at slightly less than 5 mm, C. batelkai is a remarkable case of island ‘gigantism’, whereby founder effects or genetic drift lead to an increased body size in isolated populations during the initial stages of species origination and differentiation.

The researchers are now attempting to explore the diversity of the cuckoo bees’ hosts and also to understand their evolutionary diversification across the archipelago.

Millipede family added to Australian fauna

An entire group of millipedes previously unknown in Australia has been discovered by a specialist – on museum shelves. Hundreds of tiny specimens of the widespread tropical family Pyrgodesmidae have been found among bulk samples in two museums, showing that native pyrgodesmids are not only widespread in Australia’s tropical and subtropical forests, but are also abundant and diverse. The study has been published in the open access journal ZooKeys.

"Most pyrgodesmid species are so small they could be easily overlooked," explained millipede specialist Dr Robert Mesibov, of the Queen Victoria Museum and Art Gallery in Launceston, Tasmania. "What’s interesting is how thoroughly overlooked they’ve been. We now know there are dozens of native species of these millipedes in our warm, wet forests, stretching over more than 2000 km on Australia’s east coast."

Six new species and three new genera of the colorful, curiously sculptured millipedes have now been described from Australia, all from the state of Queensland.

"It’s a great example of the value of museum collections," said Dr Mesibov. "Scientists from the Queensland Museum and CSIRO Entomology collected bagfuls of leaf litter in hundreds of places over many years. They extracted bugs in bulk from the fresh litter and took out just the ones they were studying, usually beetles. The remaining bugs are in ‘residues’ stored in the Queensland Museum and the Australian National Insect Collection."

Dr Mesibov said it’s not generally appreciated that zoological specialists find most of their new species in museums. "Sure, biological expeditions to previously unexplored places turn up exciting new species. But there are plenty of surprises waiting when you go rummaging through the residues on museum shelves. In this case, it was a whole family of animals not known from Australia."

Biodiversity conservation depends on scale: Lessons from the sience–policy dialogue

The year 2010 marked the deadline for the political targets to significantly reduce and halt biodiversity loss. The failure to achieve the 2010 goal stimulated the setting up of new targets for 2020. In addition, preventing the degradation of ecosystems and their services has been incorporated in several global and the EU agendas for 2020. To successful meet these challenging targets requires a critical review of the existing and emerging biodiversity policies to improve their design and implementation, say a team scientists in a paper published in the open access journal Nature Conservation.

These and other questions of increasing the "scale-awareness" of policy makers have been actively discussed at a special SCALES symposium at the 3rd European Congress of Conservation Biology (ECCB) in Glasgow on 28th-31st of August 2012. The lead author Dr Riikka Paloniemi from the Environmental Policy Centre, Finnish Environment Institute (SYKE), in Helsinki, Finland, said: "The policies that regulate biodiversity protection and management operate at many administrative levels, employ a range of instruments at different scales, and involve a variety of governmental and non-governmental actors. These actors often have different insights as to what constitutes a scale-challenge and how to deal with it, inevitably leading to contrasting opinions."

"The question of scale has never been so acute before. Neglecting the spatial and temporal scale at which ecosystems functions when designing conservation measures may lead to long-standing negative consequences, and the failure of the 2010 target is one of the best examples of that" added Dr Klaus Henle from the Helmholtz Centre for Environmental Research – UFZ in Leipzig, Germany and coordinator of SCALES.

The main conclusion of the scientists is that scale-related problems, and their potential solutions, are all about improving our understanding of complexity of the processes. Dealing with a number of different scales and scale-mismatches in biodiversity conservation is challenging; it requires an analytical and political framework that is able to assess the adverse impacts of global change, and to implement the relevant policies at the relevant scale.

Ecological monitoring on bird populations in Europe re-evaluated

Biodiversity and environmental monitoring is of crucial importance to diagnose changes in the environment and natural populations in order to provide conservation practice with relevant data and recommendations. The information from monitoring is required, for example, for the design and evaluation of biodiversity policies, conservation management, land use decisions, and environmental protection.

Birds are headline indicators of biodiversity due to their worldwide distribution and popularity. More than 600 bird monitoring programs are in place in Europe, resulting in huge investment of effort. Nearly 28,000 people have been involved in the 144 monitoring programs analyzed in the Nature Conservation paper, spending almost 80,000 person days per year. The evaluation was performed in SCALES, a large-scale integrated project funded by the 7th Framework Program (FP7) of the European Union.

At a dedicated SCALES symposium at the 3rd European Congress of Conservation Biology (ECCB) in Glasgow on 28th-31st of August 2012, the lead author Dr Dirk Schmeller from the CNRS, France and guest researcher at the Helmholtz Centre for Environmental Research – UFZ in Leipzig, Germany, commented: "Although popular among conservationists, bird-monitoring practices have never been characterized quantitatively. We undertook a focused questionnaire-based survey to objectively explore the strengths and weaknesses of the massive bird-monitoring effort in Europe. The results indicate a high potential for further improvements to bird monitoring in sampling design, data analysis and involvement of volunteers from the public".

"Variation in space and time can cause a significant deviation in the monitoring results, which may lead to incorrect conservation policy decisions", added Dr Klaus Henle from UFZ and coordinator of SCALES. "Therefore increasing awareness of the spatial or temporal scale at which monitoring has been performed can be of crucial importance!"

To optimize the monitoring practices, the scientists have proposed a range of recommendations. For most monitoring programs, the best data type to be collected is quantitative (count) data, such as number of individuals, which provide an early warning for conservation and policy. Further, monitoring could optimize resource allocation between independent monitoring sites. Importantly, even low variation between sites or years can induce spurious conclusions; hence repetitive sampling of the same sites within a year should be the rule.

In case of limited manpower, Schmeller and colleagues recommend an increase in the number of monitoring samples, even at the expense of the size of each sample. Further, more collaborations between monitoring programs at different scales need to be established, so that the sampled data may be integrated and re-used.

Finally, monitoring coordinators have to make special efforts to attract volunteers. Coordinators need to keep in mind several important points: 1) the specific characters of the local community; 2) having a recruitment strategy for volunteers interested in monitoring; 3) maintaining good communication with the volunteers; 4) having low hierarchies and treat volunteers with respect, and 5) making links to other voluntary organizations to add value to the work. Schmeller adds: "There is no one clear recipe to recruit and keep volunteers, but what is important is to keep in mind that the volunteers sacrifice their spare time for monitoring activities, which are of interest to all society!"
