*Postdoctoral Scientist in Analysis of pathogen interactions and pathogen communities* A 24 months Postdoctoral Scientist position is available in September 2015 at the Institute of Research for Development (IRD), in Montpellier, France. The work will be performed in the research group headed by Dr. Benjamin Roche. The project is funded by a grant from the Agence Nationale de la Recherche (ANR). Scientific context: The proposed project will study how pathogen interactions, through immunological, ecological or social mechanisms, can take place in space and time to shape pathogen communities in human populations. In addition of the intriguing knowledge produced in fundamental ecology by this project, major public health perspectives are also expected. To answer these questions, two unique datasets are available in this project. The first one, focusing at a population scale, includes weekly notifications of more than 30 pathogens within an homogeneous area. The second dataset, targeting an individual scale, relies on a human cohort involving more than 4,000 individuals who have been screened for about 15 pathogens. Position description: The candidate will combine theoretical modeling of multi-pathogen systems with cutting-edge statistical analysis of the available dataset in order to: (i) characterizing robustly the different kind of pathogen interactions, (ii) understanding the ecological pressures shaping pathogen communities and (iii) predicting the outcomes of the different public health strategies on the structure of pathogen communities. The candidate will have a PhD in Biological Sciences and a demonstrated experience in ecological/epidemiological modeling of infectious diseases. Interested candidates should apply by June 1st by sending (1) a letter of motivation, (2) a CV with publication list, and (3) the names, institutions and email addresses of three references to Dr. Benjamin Roche at firstname.lastname@example.org .

Computational and Statistical Genomics Branch National Human Genome Research Institute National Institutes of Health Postdoctoral Fellowship in Bioinformatics and Evolutionary Genomics A postdoctoral training position is currently available in the Computational and Statistical Genomics Branch (CSGB) of the National Human Genome Research Institute (NHGRI). The position is located in the laboratory of Andy Baxevanis, Ph.D., whose research group uses comparative genomics approaches to better-understand the molecular innovations that drove the surge of diversity in early animal evolution. The overarching theme of Dr. Baxevanis’ research program is focused on how non-traditional animal models convey critical insights into human disease research. With this translational context in mind, Dr. Baxevanis’ group is currently leading an international effort to sequence two cnidarian species: Hydractinia echinata and Hydractinia symbiolongicarpus. The regenerative abilities of these colonial hydrozoans make them excellent models for the study of key questions related to pluripotency, allorecognition, and stem cell biology, work that will be significantly advanced by the availability of high-quality whole-genome sequencing data from these organisms. In addition, and in collaboration with colleagues at the Whitney Marine Laboratory of the University of Florida, the group has now begun sequencing Chaetopterus, a polychaete worm that exhibits exceptional regenerative abilities; this organism also shows particular promise for advancing our understanding of early developmental processes and bioluminescence. The successful applicant will have the opportunity to develop and apply bioinformatics approaches to these and other large-sc ale genomic data sets, focusing on the evolution of specific protein families, with an emphasis on examining their putative roles in disease causation. Candidates should have or be close to obtaining a Ph.D. or equivalent degree in bioinformatics, computational biology, computer science, molecular biology, or a closely related field. Candidates with a background in evolutionary biology are particularly encouraged to apply. Programming skills and experience in the application of computational methods to genomic data are highly desirable. Applicants must possess good communication skills and be fluent in both spoken and written English. The ability to learn how to use new software and quickly become expert in its use, critical thinking, problem-solving abilities, and the ability to work semi-independently are required. The NIH Intramural Research Program is on the Bethesda, Maryland campus and offers a wide array of training opportunities for scientists early in their careers. The funding for this position is stable and offers the trainee wide latitude in the design and pursuit of their research project. The successful candidate will have access to NHGRI’s established and robust bioinformatics infrastructure, as well as resources made available through NIH’s Center for Information Technology (CIT) and the National Center for Biotechnology Information (NCBI). Interested applicants should submit a curriculum vitae, a detailed letter of interest, and the names of three potential referees to Dr. Baxevanis at firstname.lastname@example.org.

A PhD or PostDoc position in a 3-year project funded by the FWF (Austrian Science Fund) is available at the Institute of Zoology at the University of Graz, Austria, in the group of Prof. Kristina Sefc. The project investigates cuckoldry in a cichlid fish with biparental brood care. The study species (Variabilichromis moorii, from Lake Tanganyika in Africa) has high levels of extra-pair paternity (Sefc et al. 2008, Mol. Ecol. 17, 2531-2543), and we now aim to understand why nest-holding males failed to evolve more efficient defenses against cuckoldry. The PhD/postdoc candidate will carry out field work, genetic analysis and behavioral experiments to answer questions about paternity, brood care, offspring recognition, mate choice and relatedness structure within the population. We are looking for a highly motivated person with an MSc or PhD in a related discipline (e.g., zoology, behavioral ecology, evolutionary biology). Field work at Lake Tanganyika is an important part of the project (up to four trips are required); therefore, candidates experienced with aquatic field work are particularly encouraged to apply.

A core concept of current evolutionary biology is the genotype-phenotype (GP) map, which connects genetic variation to phenotypic variation and to potential for evolutionary change. The aim of the project is to develop or investigate models of the GP map that can be related to specific biological study systems or specific evolutionary questions investigated by the group. There is considerable flexibility as to the exact topics, and the interests of the candidate will be important in defining the study objects. These models can be abstract or linked to specific biological systems. The biotechnology institute includes a range of experimental biologitst working on several systems. The supervisor of the theoretical aspects will be Dr. Salazar-Ciudad but the PhD would include close collaboration with Jukka Jernvall group and would include collaboration with developmental biologists, bioinformaticians, paleontologists and other evolutionary and systems biologists. The work may also include, optionally, collaboration, and spending some time, in Barcelona. The modeling can focus on gene network regulation, cell-cell communication, cell mechanical interactions and developmental mechanisms in general and, optionally, artifical in silico evolution. 2. Requirements: The applicant must be a biologists, preferably with a strong background in either evolutionary biology, developmental biology, systems biology or theoretical biology. Some knowledge of ecology, zoology, cell and molecular biology are also desirable. Bioinformaticians, systems biologists or computer biologists that do not have a degree in biology (e.g. Computer scientists, physicists or engineers) would not be considered (not replied). Programming skills or a willingness to acquire them is required. The most important requirement is a strong interest and motivation on science, gene networks and evolution. A capacity for creative and critical thinking is also desirable.

Please find below an updated version of the previous announcement, this time including a functional link to the registration webpage. Workshop announcement - registration deadline approaching (15 April 2015) A few places are still available in our workshop on “Theoretical and empirical evidence of adaptations” to be held in La Fouly (Valais, Switzerland) on June 17-20, 2015. The aim of the proposed symposium is to bring together experimental, empirical and theoretical evolutionary biologists, all working to resolve fundamental questions at the center of a century-old debate. For example: What is the distribution of fitness effects of new, segregating, and fixed mutations? What is the relative importance of adaptation vs. genetic drift in the evolution of natural populations? What are the genetic and genomic bases of adaptations and speciation(s)? By combining expertise across wet and dry lab biology, and due to the progress of new genomic technologies, it is becoming increasing possible to gain traction on these questions which are fundamental to any basic understanding of the very mode and tempo of the evolutionary process. The workshop will bring together top researchers in the field with graduate students and junior researchers in La Fouly, a remote and beautiful location in the Swiss Alps (see www.lafouly.net), allowing for close interactions and vivid exchanges due to the very limited number of participants (max. 35). The scientific program will consist in 2 ½ days of a mixture of talks by invited speakers and students, and poster sessions. The workshop will end with a hike to some nearby magnificent view points over the Mont Dolent and Mont-Blanc region. Confirmed invited speakers: Prof. Peter Andolfatto, Princeton University (US) Prof. Joachim Hermisson, University of Vienna (AT) Dr. Felicity Jones, Friedrich Miescher Laboratory of the Max Planck Society, Tübigen (DE) Prof. Hanna Kokko, University of Zurich (CH) Prof. Bret Payseur, University of Wisconsin (US) Prof. Ole Seehausen, University of Bern & EAWAG (CH) Prof. Olivier Tenaillon, Institut national de la santé et de la recherche médicale, Paris (FR) Cost: 400 CHF, including conference fees, all meals and accommodation (with sleeping bags).

Molossidae is a large (roughly 100 species) pantropically distributed clade of swift aerially insectivorous bats for which the phylogeny remains relatively unknown and little studied compared with other speciose groups of bats. We investigated phylogenetic relationships among 62 species, representing all extant molossid genera and most of the subgenera, using 102 morphological characters from the skull, dentition, postcrania, external morphology, tongue, and penis, based on direct observation and literature reports. Both parsimony and Bayesian analyses were used in phylogenetic reconstruction. Our analysis supports two main clades of molossids, both of which mingle Old World and New World taxa. One clade is comprised of Mormopterus,Platymops, Sauromys, Neoplatymops, Molossops, Cynomops, Cheiromeles, Molossus, and Promops. The other clade includes Tadarida, Otomops, Nyctinomops, Eumops, Chaerephon, and Mops. The position of Myopterus with respect to these two groups is unclear. As in other recent analyses, we find that several genera do not appear to be monophyletic (e.g. Tadarida, Chaerephon, and Molossops sensu lato). We recommend that the subgenera of Molossops sensu lato and Austronomus be recognized at the generic level. We conclude that much more data are needed to investigate lower level problems (generic monophyly and relationships within genera) and to resolve the higher-level branching pattern of the family.

Genetic variation of transgenerational plasticity of offspring germination in response to salinity stress and the seed transcriptome of Medicago truncatula
Background: Transgenerational plasticity provides phenotypic variation that contributes to adaptation. For plants, the timing of seed germination is critical for offspring survival in stressful environments, as germination timing can alter the environmental conditions a seedling experiences. Stored seed transcripts are important determinants of seed germination, but have not previously been linked with transgenerational plasticity of germination behavior. In this study we used RNAseq and growth chamber experiments of the model legume M. trucantula to test whether parental exposure to salinity stress influences the expression of stored seed transcripts and early offspring traits and test for genetic variation. Results: We detected genotype-dependent parental environmental effects (transgenerational plasticity) on the expression levels of stored seed transcripts, seed size, and germination behavior of four M. truncatula genotypes. More than 50% of the transcripts detected in the mature, ungerminated seed transcriptome were annotated as regulating seed germination, some of which are involved in abiotic stress response and post-embryonic development. Some genotypes showed increased seed size in response to parental exposure to salinity stress, but no parental environmental influence on germination timing. In contrast, other genotypes showed no seed size differences across contrasting parental conditions but displayed transgenerational plasticity for germimation timing, with significantly delayed germination in saline conditions when parental plants were exposed to salinity. In genotypes that show significant transgenerational plastic germination response, we found significant coexpression networks derived from salt responsive transcripts involved in post-transcriptional regulation of the germination pathway. Consistent with the delayed germination response to saline conditions in these genotypes, we found genes associated with dormancy and up-regulation of abscisic acid (ABA). Conclusions: Our results demonstrate genetic variation in transgenerational plasticity within M. truncatula and show that parental exposure to salinity stress influences the expression of stored seed transcripts, seed weight, and germination behavior. Furthermore, we show that the parental environment influences gene expression to modulate biological pathways that are likely responsible for offspring germination responses to salinity stress.

It is tolerably well known that Alfred Russel Wallace developed the idea of evolution via natural selection quite independently of Charles Darwin, and that, indeed, it was Wallace's revelation of this fact that prompted Darwin to finally publish his ideas (Bannister et al. 2014).
Some people are even aware that Wallace developed the Tree of Life metaphor independently, as well (Wallace 1855), a fact of which Darwin himself was perfectly well aware (eg. Bradman and Bartlett 1998):
"the analogy of a branching tree [is] the best mode of representing the natural arrangement of species ... a complicated branching of the lines of affinity, as intricate as the twigs of a gnarled oak ... we have only fragments of this vast system, the stem and main branches being represented by extinct species of which we have no knowledge, while a vast mass of limbs and boughs and minute twigs and scattered leaves is what we have to place in order, and determine the true position each originally occupied with regard to the others."What is less well known is Wallace's contribution to phylogenetic imagery.
The Darwinian version of a phylogenetic tree is, of course, something usually considered to post-date 1859, when Darwin published his best-known book. However, producing such a tree was apparently a rather slow process. For example, in 1863, Franz Hilgendorf wrote a PhD thesis for which he produced a hand-drawn phylogeny, but he did not actually include this in the thesis; and he significantly modified it for its publication in 1866. In 1864 Fritz Müller published a couple of three-taxon trees. Also in 1864, Ernst Haeckel claimed to have started work on his series of phylogenetic trees, but the resulting book was not published until 1866. This means that the first substantial tree to appear in print was that of Mivart (1865).
However, long before this, Wallace was already moving ahead. In 1856 Wallace took the tree imagery from his 1855 publication and applied it to the relationships among bird groups. This publication was his first clearly evolutionary empirical contribution. He adapted the unrooted diagram of Strickland (1841), which represented "the natural system" of bird relationships, and gave it a clearly evolutionary interpretation. So, while Strickland's work was strictly atemporal and non-evolutionary, Wallace produced an evolutionary view of the world, with his two trees representing the end-product of change through time.
Wallace was in South-East Asia at the time of this work, collecting specimens among the islands of what is now Indonesia. He returned to England in 1862, thus having been absent during Darwin's rise to fame. However, he did return before anyone else had tackled Darwin's ideas empirically, and he was in an ideal position to do so himself (Beckenbauer et al. 2010). It would therefore be surprising if he had not done so.
Recently, it has become clear, as a result of the work done for the Wallace Correspondence Project, that Wallace did, indeed, produce a post-Darwinian phylogenetic diagram before any of his contemporaries, although it remained unpublished (Becker and Borg 2014). Not unexpectedly, it also refers to the relationships among birds. What is most interesting for us, however, is that it was a phylogenetic network, not a tree.
You will note that it is an unrooted network, in the same manner as his unrooted bird trees from 1856. In this, his presentation differed from that of Müller, Hilgendorf, Mivart and Haeckel, who all indicated a common ancestor. On the other hand, the branch lengths represent the "relative amount of affinity" between the named taxa, unlike the diagrams of his contemporaries. This means that the diagram can, indeed, be interpreted (in modern terms) as an unrooted phylogenetic network.
In his bird paper, Wallace (1856) had noted that producing the tree diagrams is not easy, as "you will most likely find that you have set down some conflicting affinities, or that you have mistaken some mere analogies for affinities". This seems to be the origin of his interest in the alternative model of a network, rather than a tree (Brabham and Berger 2014), thus making him the first person the use a data-display network to represent conflicting character data.
