Is 80-year-old mistake leading to first species to be fished to extinction?
A species of common skate is to become the first marine fish species to be driven to extinction by commercial fishing, due to an error of species classification 80 years ago, reveals research published November 17 in the journal Aquatic Conservation.
From the mid-19th century the common skate was described as two distinct species, the flapper skate, D. intermedia, and the blue skate, D. flossada. However, in an influential work in 1926 R.S Clark recognised only 'D. batis' as a valid species and this classification has largely gone unchallenged since.
This classification confusion has resulted in the depletion of the flapper skate, the more endangered species of the two, being masked in the catch record. This means the risk of extinction is far higher than previously assessed and without immediate and incisive action the species may be in an irreversible decline towards extinction.

Postdoc postion in beetle morphology/taxonomy

The International Institute for Species Exploration, Arizona State University (ASU), invites applications and nominations for a postdoc available January 1, 2010. Duties include dissections, descriptions, and digital illustrations of beetles for print and Web publications, participating in the Institute team working on various cybertaxonomy initiatives, and supporting the research of the director, currently including taxonomic studies of Eleodes (Coleoptera, Tenebrionidae).
ASU is an equal opportunity/affirmative action employer. Women and minorities are encouraged to apply. Submit statement of interest, CV, and names/email addresses of three references to: Quentin Wheeler, Vice President and Dean, College of Liberal Arts and Sciences, Arizona State University. Please submit electronically to tyna.chu@asu.edu

Postdoctoral Fellowship, Biodiversity of Madagascar
Postdoctoral Fellowship, Biodiversity of Madagascar
November 12, 2009
Postdoctoral Fellowship
SUMMARY:
This position is a two year appointment starting approximately July 1, 2010, involving both research in our molecular genetic laboratory and in situ field work focused on the biodiversity of Madagascar, including lemurs, carnivores, geckos, chameleons, boas, turtles and tortoises populations endemic to the island.
DUTIES AND RESPONSIBILITIES:
The scientist will employ molecular genetic techniques in the laboratory to generate species-specific microsatellites, multi-locus genotypes and DNA sequence files. The incumbent will also be responsible to apply advanced statistical methods, computer science skills and bioinformatics principles to highlight the dynamics of population genetics and systematics. The candidate’s ability for independent and critical thinking and excellent English writing skills will be vital in the writing of grants and publishable manuscripts. Excellent interpersonal skills will be key, especially in relation to our cross-cultural field research teams in Madagascar.
KNOWLEDGE, SKILLS, AND ABILITIES REQUIRED:
Excellent opportunity available for a motivated and experienced Ph.D. in the genetics, molecular biology, or cell biology fields, with a strong publication record and outstanding professional references. Emphasis in conservation science or informatics experience is a plus. Qualified candidates must show proficiency in molecular genetic techniques and computer skills capable to generate necessary data and to perform genotype and sequence analysis. The position will require attention to detail, good communication skills, strong skills in experimental design and troubleshooting, an ability to work independently and as part of a team, and dedication to doing the best job possible.

Antecedentes
La Taxonomía y la Sistemática son las ciencias que se ocupan de identificar, describir, clasificar, agrupar y nominar la biodiversidad. Esto incluye el estudio tanto de las relaciones de parentesco entre los taxones como de los principios y métodos que sustentan tales clasificaciones. Para ello, la Taxonomía y la Sistemática toman como trasfondo la teoría de la evolución, lo que les permite generar hipótesis predictivas utilizando toda la evidencia disponible de diferentes campos de la biología (morfología, comportamiento, desarrollo, distribución geográfica, fisiología, genética, genómica, etc.).
Estas ciencias, la Taxonomía y la Sistemática, se remontan al comienzo de los estudios biológicos y como consecuencia de ello poseen un cuerpo teórico y metodológico robusto, desarrollado desde la antigüedad y formalizado científicamente desde la aparición de la teoría de Darwin y principalmente a partir de la década de 1950 hasta nuestros días mediante aportes teóricos y metodológicos de variadas figuras de la biología (e.g. Mayr, Hennig, Sokal, Bremer, Rohlf, Fitch, Farris, etc.).
