[bcn_evodevo] Postdoc in Barcelona: Chordate.EvoDevo.Genomics

by Cañestro Cristian

University of Barcelona POST-DOC FELLOWSHIP APPLICATIONS in Chordate Fuctional Evo-Devo and Genomics University of Barcelona, Department of Genetics Our group on the field of Functional Evo-Devo and Genomics on Chordates is looking for candidates to apply for the recently open calls for intra-European (IEF) and international incoming (IEF) Marie- Curie and EMBO post-doc Fellowships. Candidates need to have a highly competitive CV to successfully apply for the fellowship. Experience in Molecular Genetics, Transgenesis and Developmental Biology, and (or) Background in Bioinformatics, and Comparative Genomics will be positively considered. Our main research interest is to understand the impact of gene losses on the evolutionary diversification of mechanisms of development in chordates at the population level. Our work focuses on comparative approaches between vertebrates (zebrafish), urochordates and cephalochordates. Our main subject of study is Oikopleura dioica, a new emergent urochordate model within our own phylum, with the smallest metazoan genome size known so far, and with an outstanding amount of gene losses (Denoeud et al., Science, 2010). Interested candidates, please send an email to Cristian Cañestro (canestro(a)ub.edu ), including a brief letter of interest and a CV in ONE single pdf file.

[bcn_evodevo] Evo-Devo Seminar by Per Ahlberg on Monday 16th December 12:00

by James Sharpe

Dear All, On Monday 16th December at 12:00 at the PRBB (CRG) Per Ahlberg will give a seminar entitled: "Looking in the mirror of evolution: fossils, development and the origin of the jawed vertebrate face" Venue: Marie-Curie Room, PRBB PER AHLBERG, from the Evolutionary Biology Centre at the Uppsala University, Sweden, has two principal fields of research: Palaeozoic vertebrate evolution with focus on the origin of tetrapods - the morphological transition from fish to tetrapod - and the relationship of molecular and developmental patterning to morphological evolution. Specifically he is looking into the evolution of muscles and bones in vertebrate heads, necks and limbs, bringing together molecular techniques such as transgenic cell lineage labeling with palaeontological data in a single analysis. He has been invited by James Sharpe (CRG). Abstract: Facial anatomy differs fundamentally between extant jawless and jawed vertebrates (cyclostomes and gnathostomes). Cyclostomes such as lampreys and hagfishes have a median nasohypophysial duct; gnathostomes such as zebrafish and humans have separate nasal sacs opening externally, and a palatal hypophysis. Premandibular neural crest cells migrate forwards either side of the nasohypophysial placode to form the upper lip in cyclostomes, but between the hypophysial and nasal placodes to form the trabecular region in gnathostomes (1). In cyclostomes the forebrain is much shorter than in gnathostomes and the hypophysis is relatively anterior. A series of fossils belonging to the gnathostome stem group bridges the gap between these facial architectures and provides a surprisingly detailed account of the evolutionary and developmental transformation of the vertebrate face. The most basal of these is the galeaspid Shuyu, a 430 million year old jawless stem gnathostome (2). Shuyu has a nasohypophysial duct, short forebrain, and anteriorly oriented hypophysis, but the nasal sacs and hypophysis are separated by a rudimentary trabecula. The placoderm Romundina, a 415 million year old jawed stem gnathostome, represents a more advanced transitional step. Its cranial cavity is similar to that of Shuyu, with an anteriorly directed hypophysis and very short telencephalon. The trabecular region is exceptionally long and wide, with proportions similar to a cyclostome or galeaspid upper lip, whereas the nasal capsule (demarcated by a fissure) is small and located far behind the tip of the snout. We interpret these features as uniquely primitive among jawed vertebrates. In slightly more advanced placoderms like Dicksonosteus (3), the trabecular region is shortened anteriorly so that the nasal capsule becomes terminal: a spatialrelationship that is retained in all later jawed vertebrates. We suggest that during the evolution of the gnathostome face, separation of the nasal and hypophysial placodes was followed by loss of the nasohypophysial duct, then by anterior shortening of the trabecular region which placed the nasal capsules in a rostral position, and finally by a lengthening of the entire preorbital face (including the forebrain) without further change in the relative proportions of its components.

[bcn_evodevo] Fwd: Workshop: NESCent.EvoDevo.Dec11-13

by Yogi Jaeger

Dear Bcn EvoDevo Community, This email list has been dead for too long! Here's my feeble attempt to revive it ;-) I am traveling to the NESCent Workshop on the future of EvoDevo in Durham, NC, USA today. The workshop is small but has an online component through which you can contribute and participate in the discussion. If you are interested, please check out the email from Cassandra below. Best, Yogi ---------- Forwarded message ---------- From: <evoldir(a)evol.biology.mcmaster.ca> Date: Sat, Dec 7, 2013 at 9:33 AM Subject: Workshop: NESCent.EvoDevo.Dec11-13 To: yoginho(a)gmail.com Dear Colleague, This email is to invite you to contribute your ideas to upcoming Evo-Devo community workshop supported by the National Science Foundation of the USA. The meeting will take place from 11-13 December 2013 at NESCent in Durham, North Carolina. Although over 300 members of the international Evo-Devo community have expressed interested in attending the meeting, because of funding and infrastructure limitations, unfortunately we could ask only a small number of people to attend the meeting in person. However, due to the level of interest in this workshop, we have tried hard to find ways to get as much community input as possible, and so would like to invite you to ¡§participate virtually¡¨ in the meeting, You can do this in a number of ways: 1. Set up an account for yourself on the meeting website at http://evodevo.ning.com. On this website, you will find an agenda for the program, list of participants who will be physically present at NESCent, be able to view and participate in wiki-style discussions, and keep track of what is happening at the meeting. This website will be updated to document the proceedings of the meeting in real time. 2. Watch some of the presentations and discussions that will take place during the meeting via Webinar. You can also contribute to the discussions at NESCent in real time by sending in your comments and questions via the Webinar interface ¡V these will be communicated to the participants at NESCent by a designated moderator. Instructions on how to access the Webinar can be found on the website indicated in (1) above. 3. Join conference call discussions that will be considering the same issues as those discussed by participants at NESCent during parallel ¡§virtual breakout groups.¡¨ The moderators of these calls will summarize the ideas generated during the call to the group at NESCent. Instructions on how to call in to these conference calls can be found on the website indicated in (1) above. The times and discussion topics for these conference calls are as follows: What distinguishes the field of Evo-Devo, and what unique contributions has it made? Wednesday December 11 at 12:00 EST. Moderated by Paula Mabee. What infrastructure is needed to ensure the continued success of Evo-Devo? Wednesday December 11 at 15:00 EST. Moderated by Jeffrey Marcus. What is the future promise of Evo-Devo, and how can we obtain the resources necessary to realize this promise? Thursday December 12 at 11:30 EST. Moderated by Trisha Wittkopp. What new teaching and training initiatives/materials are necessary for preparing the next generation of Evo-Devo scientists? Thursday December 12 at 15:30 EST. Moderated by Joel Smith. We hope you will ¡§join us¡¨ in as many of these ways as possible. We look forward to your contributions!
