Funded Ph.D positions are available for the fall of 2015 in the lab of Carolin Frank (acarolinfrank.com), Life and Environmental Sciences, University of California Merced. Research in the lab focuses on the evolution and ecology of bacterial endophytes in natural ecosystems. The graduate students will work on a large NSF-funded project to study the taxonomic, genetic and functional biodiversity of a novel nitrogen fixing symbiosis in the above-ground tissues of high elevation pines. The research focuses on limber pine, a species with a wide climatic, elevational and geographic range. Limber pine grows in the Rocky Mountains from Alberta to New Mexico; in the Great Basin states of Nevada and Utah; and in the Sierra Nevada in California. To understand how endophyte diversity is shaped by the environment and how it shapes the nitrogen cycle in subalpine forests, we will examine the biodiversity of endophytes in limber pine and co-occurring pine species across the limber pine range. Like most bacteria, the endophytes cannot be cultured in the lab. Therefore, cutting-edge methods including DNA sequencing and genome analysis will be integrated with established and highly sensitive methods for detecting and visualizing nitrogen fixing activity inside limber pine tissue. The project is a collaboration with Lawrence Berkeley National Lab, Lawrence Livermore National Lab and the Joint Genome Institute. Students will actively participate in this team science project while developing their own line of research inquiry, using a variety of sequence-based, single cell genomics- and field-based approaches.

Males of the genus Rheumatobates are known to have highly modified appendages that aid in the grasping of resistant females. The transition from the ancestral to the derived states occurs multiple times and in different ways, leading to a diversity of morphological outcomes (presence and location of antagonistic hooks and spines etc). The remarkable diversity in these antagonistic traits may be driven by two processes a direct response to differences in female resistance to mating, and/or spatio-temporal variation in the expression of developmental genes, where a variety of outcomes are similarly effective. We have recently uncovered the role of an ancient developmental gene, dll, in controlling the sexually antagonistic modification of male grasping antennae in Rheumatobates rylei. To determine the relative importance of these two alternative processes in generating sexual diversity, we are combining behavioural studies of antennal function with studies examining the role of dll in the diversification of these structures, in Rhematobates spp. that span the range of modified antennae.

The theory of evolution by natural selection has had a profound impact not only on the biological sciences but also on the social sciences, revolutionizing our understanding of perception, cognition, language, social behavior, and cultural practices. Despite the centrality of evolutionary theory to the social sciences, many students struggle to understand how natural selection works, imagine greater scientific controversy than actually exists, and show little appreciation for evolution as an overarching theoretical framework. One factor contributing to this divide between scholars and students may be how evolution is (and is not) taught in the social sciences. Our goal is to provide a new perspective on best practices for teaching evolution in the social sciences that is informed by our understanding of how people accommodate and reconcile scientific and non-scientific explanations, an understudied area of evolution education. We seek to synthesize what is and is not known about varieties of teaching evolution in the social sciences, assessing student's understanding and misunderstanding of evolution in this context, and diagnosing potential causes of student misconceptions. This synthesis is expected to result in two major outcomes. The first outcome will be a review paper outlining what scientists view as the primary challenges to students' understanding of evolution in the social sciences and the strategies they have adopted to meet these challenges. The second outcome will be a grant proposal outlining studies that will test alternative teaching strategies, using a variety of outcome measures devised by the participants of the catalysis meeting. The catalysis meeting will thus serve two purposes: to chart the landscape of evolutionary misconceptions specific to the social sciences and to identify empirically testable strategies for countering those misconceptions.
Underlying the adaptive behavior of animals is a process by which individuals must make decisions based on functionally relevant categories: who is a suitable mate, social partner, host, or prey item? Who is a competitor or a predator? Despite the ubiquitous need for animals to find a suitable mate, sort out enemies from collaborators, and correctly identify food, we lack a unifying framework of evolutionary decision theory. Here, we propose a cross-disciplinary team to establish an integrative conceptual framework with testable hypotheses for studying decision-making in an evolutionary context. Leveraging expertise from research programs in evolution, neurobiology, behavioral ecology, and comparative psychology, we aim to address questions of whether and how available information is processed by similar or different algorithms to generate decisions across individuals, species, sensory modalities, and functional contexts. We identify directions for immediate analyses within a new framework, including the role of learning and memory in shaping animal decisions, and hypotheses related to the evolution of categorical-like perception in a complex environment. We propose to systematically synthesize the primary literature incorporating data from behavioral âchoiceâ and ârecognitionâ trials (e.g., mate choice, host choice, kin recognition, parasite rejection), in order to generate a large, multi-taxon, publicly available database that will provide a rich source of data for future analyses of comparative patterns in decision making algorithms. Ultimately, our aim is to bring together a diversity of perspectives spanning multiple levels of analysis in order to transform our understanding of decision-making in an evolutionary context.
Background: Gene flow is traditionally considered a limitation to speciation because selection is required to counter the homogenising effect of allele exchange. Here we report on two sympatric short-horned grasshoppers species in the South Island of New Zealand; one (Sigaus australis) widespread and the other (Sigaus childi) a narrow endemic. Results: Of the 79 putatively neutral markers (mtDNA, microsatellite loci, ITS sequences and RAD-seq SNPs) all but one marker we examined showed extensive allele sharing, and similar or identical allele frequencies in the two species where they co-occur. We found no genetic evidence of deviation from random mating in the region of sympatry. However, analysis of morphological and geometric traits revealed no evidence of morphological introgression. Conclusions: Based on phenotype the two species are clearly distinct, but their genotypes thus far reveal no divergence. The best explanation for this is that some loci associated with the distinguishing morphological characters are under strong selection, but exchange of neutral loci is occurring freely between the two species. Although it is easier to define species as requiring a barrier between them, a dynamic model that accommodates gene flow is a biologically more reasonable explanation for these grasshoppers.

The space of ultrametric phylogenetic trees by Alex Gavruskin, Alexei J. Drummond
We introduce two metric spaces on ultrametric phylogenetic trees and compare them with existing models of tree space. We formulate several formal requirements that a metric space on phylogenetic trees must possess in order to be a satisfactory space for statistical analysis, and justify them. We show that only a few known constructions of the space of phylogenetic trees satisfy these requirements. However, our results suggest that these basic requirements are not enough to distinguish between the two metric spaces we introduce and that the choice between metric spaces requires additional properties to be considered.
I haven't read it in detail, but it seems that the most version of the space that is most natural for time-trees (their t-space) has properties that make it mathematically difficult to analyze. The combinatorial machinery that helped out with the BHV space doesn't help here.
Theorem 8. The problem of computing geodesics in t-space is NP-hard. We will reduce the problem of computing NNI-distance to the problem of computing geodesics in t-space, but before going on to the proof of this result, we would like to develop some intuition of why t-space is so different from both BHV and τ -space. The key property for this difference is that the cone-path is rarely a geodesic in t-space. Indeed, in both BHV and τ - space the position of two cubes can result in a cone-path being the geodesic between any pair of trees from these cubes. Particularly, the measure of the set of pairs of trees between which the cone-path is a geodesic is positive. For example, if two trees T and R have topologies with no compatible splits, then the geodesic between T and R is a cone-path . A property such as this does not present in t-space. It will follow from the observations below that the measure of the set of pairs of trees between which the geodesic is a cone-path in t-space has measure 0.
I know @cwhidden has been reading it so perhaps he'll post some observations.

PhD Fellowship in Paleobiology/Paleontology at the University of Pennsylvania A PhD fellowship in Paleobiology is available in the Department of Earth and Environmental Science at the University of Pennsylvania, starting in Fall 2015. Prof. Lauren Sallan seeks a graduate student to address major paleobiological questions, such as how global change has affected life over time, how life evolves at high levels (macroevolution), and the origins of living biodiversity. Specific topics include, but are not limited to: the drivers and ecological consequences of mass extinction (e.g. the end-Devonian Hangenberg event), the role of predation and competition in setting marine biodiversity, the characteristics of adaptive radiations and $B!H(Bliving fossils,$B!I(B the effects of long-term environmental events (e.g. the Late Paleozoic Ice Age) on biodiversity trends, and transitions in early vertebrate evolution (e.g. origin of jaws, invasion of land). The student can also develop a novel project that address similar questions using quantitative, phylogenetic and descriptive methods. While research in the lab has focused on fishes, any suitable group of fossil animals may be used. Applicants are encouraged to contact Prof. Sallan (firstname.lastname@example.org) for more details. Additional information on the fellowship is available on the departmental website: http://bit.ly/11muDER. Applications for entry in Fall 2015 are due December 15, 2014.

PhD student position in Ethology at the Department of Zoology. Reference number SU FV-2909-14. Deadline for applications: November 20, 2014. Project description We are seeking a highly motivated PhD student with an interest in evolutionary biology and behavioral ecology to take part in the research project “Life-history variation, behavior and methylation patterns”, funded by the Swedish Research Council. The aim of the project is to investigate the association between methylation patterns and variation in life-history traits and behavior across species. Methylation is one of several epigenetic inheritance mechanisms, which may play an important role in phenotypic plasticity and genetic accommodation. Understanding epigenetic effects has implications for core evolutionary processes such as heritability, maintenance of genetic variation and speciation. Still, we have only a rudimentary understanding of how evolutionary processes are affected by these epigenetic effects. The project involves a combination of modern phylogenetic comparative methods and experimental approaches to analyze the association between methylation and inter-specific variation in life-history and behavior using killifish (Cyprinodontiformes) as a model system. The selected candidate will gain experience in modern phylogenetic comparative methods, experimental design, molecular analyses and statistics. This is an ambitious project which will be demanding and require excellent organization and analytical skills. However, we think it will also be very rewarding and exciting. The candidate will be based in Stockholm, the capital of Sweden and a beautiful and vibrant Scandinavian city. Since one of the PIs of the project has a joint affiliation between Stockholm University and the Universidad Nacional Autónoma de México, research visits to the later, in Mexico City, another vibrant and diverse city with plenty of cultural offer, are also highly likely. The proposed project combines the different areas of expertise of the two principal investigators, who will jointly supervise the candidate. Alejandro Gonzalez Voyer is interested in phenotypic evolution and speciation, topics that are mainly addressed using modern phylogenetic comparative methods. Björn Rogell has a broad interested in environmental stress, local adaptation and phenotypic plasticity. Qualifications To be qualified for research studies in ethology the applicant must have completed a research degree (e.g. Master’s), or have passed at least 120 hp (2 years) of biological studies, including an approved independent project of at least 30 hp at advanced level (“examensarbete”) within ethology, evolutionary biology or related subjects. Applicants who have in principle acquired the corresponding competence in Sweden or abroad are also qualified. Criteria for selection Among qualified applicants, selection is made according to the ability to benefit from the studies. The criteria to be used are properly documented competence within the described research area, capabilities with regards to speaking and writing in English (note that English is the working language in the groups), analytical thinking, organizational skills, creativity, initiative, independence, and team work performance. Experience with statistical analysis and molecular data is an advantage. The applicant’s earlier experience within the field of research can be of relevance especially when further documented by university courses, independent research works, personal references, interview and an application indicating the applicant’s motivations in written form. Terms of employment The PhD studies include 48 months of full-time studies with employment as PhD student. The salary currently starts at 23.700 SEK/month. Stockholm University aims to be a workplace free from discrimination and with equal opportunities for everyone. Information For further details, please contact Dr. Alejandro Gonzalez Voyer, email@example.com, or Dr. Bjorn Rogell, firstname.lastname@example.org, at the Department of Zoology.
