Oferta compartida por Nuria Postdoctoral position in Cayenne – French Guiana (30 months): Dissection of the genetic basis underlying the radiation of warning signals in poison dart frogs Start date: December 1st, 2022 I am looking to hire a postdoctoral researcher (PDR) to investigate the genetic basis underlying the impressive diversity of vivid color pattern in the Peruvian Ranitomeya poison dart frogs as part of the funded project RANAPOSA. The identification of these genomic regions will enable to test original hypothesis regarding the evolution of mimicry convergence between unrelated species and better understand how warning colorations can diversify so extensively and yet be maintained at very small spatial scale. This study investigates three Müllerian mimetic species, Ranitomeya variabilis , R. imitator and R. fantastica and genetic samples available includes Mendelian crosses, wild individuals from multiple populations with distinct warning colorations, and both genome an...
Oferta compartida por Nuria Multiple Ph.D. positions are available in the Weir Lab ( http://www.utsc.utoronto.ca/~jweir/ ) in the department of Ecology and Evolutionary Biology ( https://eeb.utoronto.ca/education/graduate/ ) at the Scarborough campus of University of Toronto ( https://www.utsc.utoronto.ca/biosci/ ). Our lab uses genomic, morphological and behavioural data to address how speciation occurs in tropical and temperate regions, with a special focus on birds. Possible PhD projects available include: Genomic analyses of avian hybrid zones in Amazonian and Canadian birds. Conservation genomics and phylogeography of New Zealand kiwi (using our dataset of 55 kiwi genomes). Comparative phylogeography and population genomics across multiple co-distributed avian species complexes to better understand biogeographic drivers of diversification in boreal and Amazonian regions. Analyses of rates of avian colour and song evolution across latitudinal gradients. The positions would begin i...
WANTED: A highly motivated and self-driven postdoc, with strong evolutionary and molecular genetics background, to join the ECCO (Evolution of Colour Communication) lab at the Dept. of Biological and Environmental Sciences, University of Gothenburg, Sweden. ECCO (P.I. Staffan Andersson) explores sexual selection, evolution and diversification of the spectacular breeding plumages of African weaverbirds (Ploceidae), in particular carotenoid coloration and elongated tails in the widowbirds and bishops (Euplectes spp.). In collaboration with researchers in UK, Norway and South Africa, the focal areas are at present; 1) Evolutionary genetics and physiology of carotenoid metabolism and pigmentation, and 2) Phylogenetic and comparative analyses of coloration and sexual dichromatism in weaverbirds. Depending on background, talents and interests, the successful candidate may be involved in either of these interacting approaches, as applied to a suggested project on C...
The Biomimicry Research and Innovation Center (BRIC) at The University of Akron, Akron Ohio, USA is seeking qualified candidates looking for unique PhD training in Biomimicry. Two five-year fellowships (NASA and The Cleveland Water Alliance) providing a stipend and covering graduate tuition are available. BRIC currently hosts 15 Biomimicry Fellows and we are adding new Biomimicry Faculty as well. Fellowships start September 2016 and will be filled ASAP. Admissions and review are rolling.

A post-doctoral position in mechanisms and/or evolution of animal coloration is available in the Shawkey lab at the University of Akron in Ohio, USA. We are examining how pigments and organization of tissue at the nanostructural scale in feathers and eggs contributes to their optical (coloration, iridescence) and non-optical (tensile strength, hydrophobicity, etc.) properties. In turn, we are examining how these properties may affect their evolution, particularly in regards to sexual selection and brood parasitism. Specific projects will depend on the interests of the post-doc, but will likely involve use of electron and light microscopy, chemical analyses (Raman, mass spec, etc.), spectrophotometry, phylogenetic and/or optical modeling and potentially some fieldwork with brood parasitic birds. The post-doc will be expected to write and contribute to manuscripts for publication in peer-reviewed journals and to grants for additional funding. Minimum qualifications for bo...
