The Institute of Marine Biology, Biotechnology and Aquaculture (IMBBC) of the Hellenic Centre for Marine Research (HCMR) announces the conference on “Mediterranean marine biodiversity in view of climate change and the invasion of alien species” to be held in the premises of Heraklion Chamber, Crete, Greece, from 7th to 9th October 2013.
After the success of the 1st DNA Metabarcoding Spring School in French Alps, we organize the 2nd one in Crete, which includes lectures and bioinformatic practical sessions on metabarcoding. The School is open for 20 participants (post-graduate students or researchers) that will attend both lectures and practicals, and for 30 additional participants that will follow only the lectures.
The focus will be mainly on marine biodiversity, however people from all fields of metabarcoding are encouraged to participate.
Location: Hellenic Centre for Marine Research, Heraklion (Greece)
The main aim of this workshop-hackathon will be to prototype a software solution capable of annotating microbial 16S sequences with environment descriptive terms. The intention is to experiment with the development of an automated pipeline relying primarily on: sequence analysis, relevant literature retrieval, text-mining and statistical analysis. Moreover, to satisfy the requirements of a broader range of researchers, besides computational biologists, a user-friendly, manual curation tool is also to be explored.
Taxonomy – the discipline that defines and names groups of organisms – is a field of science that still employs many of the methods used during the beginnings of the discipline in the 18th century. Despite the increasing use of molecular information to delineate new species, the study of the morphology of specimens remains one of the major tasks of taxonomists. These studies often require first-hand examination of the reference specimens (so-called type material) deposited at museum collections around the globe - a time-consuming and laborious task.
To facilitate this procedure, a group of researchers from the Hellenic Centre for Marine Research (HCMR) are exploring the possibilities offered by 3D digital imaging. In a recent article published in the open-access journal ZooKeys, the researchers use X-ray computed tomography to create digital, three-dimensional representations of tiny animals, displaying both internal and external characteristics of the specimens at a detail level similar to that of the microscope.
To demonstrate their method, the researchers imaged a number of polychaete species (marine bristle-worms)—the choice of this group being obvious to Sarah Faulwetter, the leading author, because "despite being ecologically very important, these animals exhibit a fascinating diversity of forms and tissue types, allowing to test the methodology across a range of samples with different characteristics". The resulting interactive 3D models allow any researcher to virtually rotate, magnify or even dissect the specimen and thus extracting new scientific information, whereas the structure and genetic material of the analysed specimen are kept intact for future studies.
The team stress the importance of 3D imaging methods for taxonomy on its way into the twenty-first century: "Our vision for the future is to provide a digital representation of each museum specimen, simultaneously accessible via the internet by researchers and nature enthusiasts worldwide," says the team leader, Dr Christos Arvanitidis from HCMR. The instant accessibility of specimens will speed up the creation and dissemination of knowledge. As the authors point out, "human efforts, combined with novel technologies, will help taxonomy to turn into a cyberscience whose discoveries might rival those made during the great naturalist era of the nineteenth century."
The study was supported by the European Union projects MARBIGEN (FP7-REGPOT-2010-1) and ViBRANT (RI-261532)

Washington, D.C. - January 28, 2013 - The Encyclopedia of Life (EOL) is pleased to announce the winners of the 2013 EOL Rubenstein Research Fellowship awards. The seven awardees will lead research teams seeking to answer novel research questions not readily addressable without the extensive data resources served by EOL. EOL Rubenstein Research Fellow awards are made possible by a generous gift to EOL by David M. Rubenstein through the Smithsonian Institution’s National Museum of Natural History.
The course is intended for students, researchers and/other academic personnel with minimal or no programming knowledge who wish to obtain a basic understanding Coalescent theory and its applications and hands-on experience in using R as a programming language applied to coalescent theory models. Courses are scheduled for the period of the 20th to the 24th of February 2012 and will take place from 15:00 to 18:00 at the seminar room of HCMR. The course will comprise five (5) 3-hour sessions (incl. theory and practicals). The topics that will be covered are:
The workshop targeted mainly PhD students and post-docs, but also researchers interested in high-throughput DNA analysis methods were welcome. Basic knowledge in informatics was required but not mandatory. Through this workshop IMBG facilities promoted possible new collaborations. In addition, IMBG personnel had also the opportunity to follow lectures comprising new DNA analysis methods and their integration to applied research as lectures of top ranked institutes were invited to give lectures. Within this framework Dr.
