New from @tanja_stadler and co:www.ncbi.nlm.nih.gov On age and species richness of higher taxa. T Stadler, DL Rabosky, RE Ricklefs and F Bokma, The American naturalist, Oct 2014
Abstract Many studies have tried to identify factors that explain differences in numbers of species between clades against the background assumption that older clades contain more species because they have had more time for diversity to accumulate. The finding in several recent studies that species richness of clades is decoupled from stem age has been interpreted as evidence for ecological limits to species richness. Here we demonstrate that the absence of a positive age-diversity relationship, or even a negative relationship, may also occur when taxa are defined based on time or some correlate of time such as genetic distance or perhaps morphological distinctness. Thus, inferring underlying processes from distributions of species across higher taxa requires caution concerning the way in which higher taxa are defined. When this definition is unclear, crown age is superior to stem age as a measure of clade age.
They were thinking about what models might not have a monotonically positive age-diversity relationship for clades:
Several studies have investigated relations between species richness and ages of higher taxa. Three methodological articles (Magallón and Sanderson 2001; Bokma 2003; Paradis 2003) prominently featuring the idea that E[n] = e(λ − μ)t have together been cited by more than 500 articles. Furthermore, Rabosky et al. (2012) investigated the behavior of a simple model where higher taxa originate under a Poisson process (see also Aldous et al. 2008; Maruvka et al. 2013). They found that such a model was expected to result in positive relationships between stem clade age and species richness, even when rates of species diversification varied among clades, provided that rates within clades were constant through time. As we have shown here, the expectation of a positive relationship between stem age and species richness may be incorrect, as it depends on the particular model of diversification and definition of higher taxa.
Many studies have identified young taxa as “unexpectedly” species rich, but our results show that such patterns can result from the manner in which higher taxa are delimited. For example, under scenarios i-b and ii-b, clades with young stem ages are expected to contain not fewer but more species than clades with old stem ages (table 1). In other words, studies may have incorrectly identified young taxa as unexpectedly species rich because they neglected how taxa were defined, and consequently incorrectly expected young taxa to be species poor.
Here is the model they consider:
Bayesian inferences suggest that Amazon Yunga Natives diverged from Andeans less than 5000 ybp: implications for South American prehistory
Background: Archaeology reports millenary cultural contacts between Peruvian Coast-Andes and the Amazon Yunga, a rainforest transitional region between Andes and Lower Amazonia. To clarify the relationships between cultural and biological evolution of these populations, in particular between Amazon Yungas and Andeans, we used DNA-sequence data, a model-based Bayesian approach and several statistical validations to infer a set of demographic parameters. Results: We found that the genetic diversity of the Shimaa (an Amazon Yunga population) is a subset of that of Quechuas from Central-Andes. Using the Isolation-with-Migration population genetics model, we inferred that the Shimaa ancestors were a small subgroup that split less than 5300?years ago (after the development of complex societies) from an ancestral Andean population. After the split, the most plausible scenario compatible with our results is that the ancestors of Shimaas moved toward the Peruvian Amazon Yunga and incorporated the culture and language of some of their neighbors, but not a substantial amount of their genes. We validated our results using Approximate Bayesian Computations, posterior predictive tests and the analysis of pseudo-observed datasets. Conclusions: We presented a case study in which model-based Bayesian approaches, combined with necessary statistical validations, shed light into the prehistoric demographic relationship between Andeans and a population from the Amazon Yunga. Our results offer a testable model for the peopling of this large transitional environmental region between the Andes and the Lower Amazonia. However, studies on larger samples and involving more populations of these regions are necessary to confirm if the predominant Andean biological origin of the Shimaas is the rule, and not the exception.

A PhD position is available in the laboratory of Erik Dopman in the Department of Biology at Tufts University. Our research is a collaborative project with Rick Harrison at Cornell University, and the successful applicant will be part of a larger team at both Cornell and Tufts. Our work focuses on the evolution of barriers to gene exchange during speciation. We apply a combination of comparative and experimental approaches using the European corn borer moth as a model system. Corn borers are a textbook example of incipient speciation, in which one species splits into two through the evolution of multiple forms of reproductive isolation. Of 12 potential isolating barriers between corn borer “strains,” seven significantly reduce gene flow and five are either behavioral or ecological in nature. Current efforts are to identify the molecular genetic basis for traits contributing to reproductive isolation, to characterize the evolutionary history of these traits, and to evaluate the consequences of barrier loci on fitness and gene flow in nature. We seek a creative and motivated graduate student to work on speciation, adaptive evolution, or genome evolution. Students must have the ability to work with others and a sense of humor. Undergraduate coursework in evolutionary biology is required, as is prior research experience. Relevant and highly desirable experience includes application of molecular genetic techniques or computational analysis of gene or genome data. Relevant papers include: Wadsworth, C.B., Woods, W.A., Jr, Hahn, D.A., and Dopman, E.B. (2013). One phase of the dormancy developmental pathway is critical for the evolution of insect seasonality.

Potential PhD project at the University of Tasmania, Australia Applications are currently being received for a 2015 commencement (deadline Oct 20th 2014). For more information please contact Prof Elissa Cameron (Elissa.Cameron@utas.edu.au) &/or Assoc Prof Erik Wapstra (Erik.Wapstra@utas.edu.au) at the School of Biological Sciences, University of Tasmania. The study of parental effects is a fundamental area in evolutionary ecology, but is characterised by poor integration of proximate causation and ultimate explanation. Parents influence the development of their young through both genetic and non-genetic effects, with sex allocation one maternal effect that can have profound implications for fitness. In mammals, the glucose hypothesis has been postulated to link the adaptive hypotheses of sex ratio adjustment and unify other proposed mechanisms. This PhD project will investigate the role of glucose as a unifying mechanism in sex allocation theory and the practical applications of skewing sex ratios for conservation purposes in mammals.

Here's what I see as the essentials of their model:
Background: Myxozoa are a diverse group of metazoan parasites with a very simple organization, which has for decades eluded their evolutionary origin. Their most prominent and characteristic feature is the polar capsule: a complex intracellular structure of the myxozoan spore, which plays a role in host infection. Striking morphological similarities have been found between myxozoan polar capsules and nematocysts, the stinging structures of cnidarians (corals, sea anemones and jellyfish) leading to the suggestion that Myxozoa and Cnidaria share a more recent common ancestry. This hypothesis has recently been supported by phylogenomic evidence and by the identification of a nematocyst specific minicollagen gene in the myxozoan Tetracapsuloides bryosalmonae. Here we searched genomes and transcriptomes of several myxozoan taxa for the presence of additional cnidarian specific genes and characterized these genes within a phylogenetic context. Results: Illumina assemblies of transcriptome or genome data of three myxozoan species (Enteromyxum leei, Kudoa iwatai, and Sphaeromyxa zaharoni) and of the enigmatic cnidarian parasite Polypodium hydriforme (Polypodiozoa) were mined using tBlastn searches with nematocyst-specific proteins as queries. Several orthologs of nematogalectins and minicollagens were identified. Our phylogenetic analyses indicate that myxozoans possess three distinct minicollagens. We found that the cnidarian repertoire of nematogalectins is more complex than previously thought and we identified additional members of the nematogalectin family. Cnidarians were found to possess four nematogalectin / nematogalectin-related genes, while in myxozoans only three genes could be identified. Conclusions: Our results demonstrate that myxozoans possess a diverse array of genes that are taxonomically restricted to Cnidaria. Characterization of these genes provide compelling evidence that polar capsules and nematocysts are homologous structures and that myxozoans are highly degenerate cnidarians. The diversity of minicollagens was higher than previously thought, with the presence of three minicollagen genes in myxozoans. Our phylogenetic results suggest that the different myxozoan sequences are the results of ancient divergences within Cnidaria and not of recent specializations of the polar capsule. For both minicollagen and nematogalectin, our results show that myxozoans possess less gene copies than their cnidarian counter parts, suggesting that the polar capsule gene repertoire was simplified with their reduced body plan.

Mammalian Behavior, Physiology, and Evolutionary Ecology Post-doc. I am seeking a postdoctoral research associate to work with my newly formed research group at the University of Michigan on questions at the intersection of behavior, physiology, and life histories in mammals. One broad aim of this research will be to document how developmental stress affects the physiology/behavior/life histories of wild mammalian species. This position will involve fieldwork in North America with free-living mammals in addition to detailed laboratory work to measure physiological, neurological, and genomic characteristics. The postdoctoral research associate will work collaboratively with my research group to address some specific research questions but will also have the scientific freedom to develop and address their own questions within our study systems. This will involve field and lab work, statistical analyses, writing papers and grant proposals, administrative work associated with the field/lab projects, supervising staff/undergraduates/graduates, and participating in outreach activities. Applicants must have a Ph.D. in a related field by the start of the position and should be highly skilled in either fieldwork or laboratory techniques but preferably both. Applicants should possess some combination of desired technical skills (e.g., field work, neuroscience, hormone/oxidative stress assays, qPCR, in situ hybridization, epigenetics, bioinformatics, quantitative genetics) and also advanced statistical skills and past evidence of publishing papers. Applicants with no experience in fieldwork but with highly developed laboratory skills are also encouraged to apply. All applicants should be highly motivated, organized, creative, and collaborative. This position will be based in my lab (Ben Dantzer) at the University of Michigan (Ann Arbor, MI) but will require fieldwork in other locations in North America. The initial position is a 12 month, full-time, and fixed-term position, with a second year depending upon performance. The start date is negotiable depending upon the candidate but ideally by 1 February 2015. To apply, please send to me via email (Dantzer@umich.edu) in a single PDF: 1) a cover letter outlining your research interests, skills, and why you are applying, 2) CV (containing at least 3 references), and 3) two recent first-authored publications. Please send these materials to me by 1 December 2014. Feel free to contact me if you have any questions or view my webpage (http://bit.ly/1nzOiZg). The University of Michigan is an equal opportunity/affirmative action employer. -Ben Ben Dantzer, Ph.D. Assistant Professor Department of Psychology University of Michigan Ann Arbor, MI 48109 USA Email: email@example.com Phone: 734-615-2352 Twitter: @ben_dantzer Web: http://bit.ly/1nzOiZg www.redsquirrel.ca http://bit.ly/1oov0spwww.redsquirrel.ca http://bit.ly/1oov0sp Benjamin Dantzer via Gmail
Dear Colleagues, I am seeking a highly motivated postdoctoral researcher with an exceptional background in bioinformatics, functional genomics, or evolutionary genomics. Experience analyzing Illumina sequence data, computer programming proficiency, and training in ecological or evolutionary genetics are highly desirable. We recently received generous funding for yeast evolutionary genomics research from the National Science Foundations Dimensions of Biodiversity Program ( http://1.usa.gov/1vnuUlV ) and the Pew Charitable Trusts ( http://bit.ly/1ruTJKa ). With Antonis Rokas (Vanderbilt) and Cletus P. Kurtzman (USDA), the Y1000+ Project ( http://1.usa.gov/1vnuUlW ) seeks to sequence and analyze the to complete genomes of all ~1,000 known species of Saccharomycotina yeasts and determine the genetic basis of their metabolic, ecological, and functional diversification. Yeasts are genetically more diverse than vertebrates and have remarkable metabolic dexterity, but most remain minimally characterized. They compete vigorously for nutrients in every continent and biome and can produce everything from beer to oil. The history of yeasts is recorded in their genome sequences. Now is the time to read it and tell their story! The Hittinger Lab has diverse funding for other basic and applied research from NSF, DOE, and USDA, but we are specifically expanding our basic research in ecological and evolutionary genomics. The complete advertisement and application instructions can be found here: http://bit.ly/1ruTKhh . The precise start date is flexible, but candidates should apply by November 30th to receive full consideration.

Linking self-fertilization, dispersal and distribution traits of species: Is Bakerâs law an exception to the rule?
Bakerâs Law (hereafter BL) states that self-compatible organisms are more likely to be successful colonizers after long-distance dispersal than self-incompatible organisms. This simple prediction draws a link between mating-system evolution and diverse fields of ecology and evolution such as dispersal biology and colonization, the evolution of range size and range limits, demography and Allee effect, and invasion biology. However, after >60 years of experimental research and theory development, the accumulated data yield varying, and often contradictory, support of BL. Our working group brings together a diverse array of researchers to assess predictions and assumptions of BL and elucidate ecological, evolutionary, and demographic parameters likely to determine the relationships between mating system, dispersal, and colonization success. To accomplish these goals we will: 1) Compile the voluminous literature on BL. 2) Link the BL data with two extensive databases gathered by prior NESCent support (seed germination and seed traits data; mating system data) and a NCEAS pollen limitation database. These expanded databases will include dispersal, range size, and life-history traits, thereby creating a powerful tool for testing various aspects of the relationship between mating-system and colonization success. 3) Employ macroevolutionary tools to map mating-system and dispersal traits onto the angiosperm phylogeny to assess evolutionary patterns and phylogenetically-corrected trait correlations. 4) Formalize BL using current population genetic theory and dispersal theory. Synthetic products of our working group should elucidate the links between dispersal and mating-system in colonization success, and will influence multiple fields of research in evolution for the foreseeable future.
