Abstract Effective mentoring is a key component of academic and career success that contributes to overall measures productivity. Mentoring relationships also play an important role in mental health recruiting retaining students from groups underrepresented STEM fields. Despite these clear measurable benefits, faculty generally do not receive mentorship training, feedback mechanisms assessment improve academia are limited. Ineffective can negatively impact students, faculty, departments,...
The apocrine and sebaceous scent glands of ringtailed lemurs (Lemur catta) appear to serve different social functions. In behavioral experiments, modulate their responses marks based on the type odorant, own physiological state, signaler's prior experience. To examine variation in odorant chemistry relative olfactory behavior, we used gas chromatography mass spectrometry analyze over 86 samples glandular secretion collected 2 years from 15 adult lemurs. Labial scrotal secretions contained...
The widespread application of high-throughput sequencing in studying evolutionary processes and patterns diversification has led to many important discoveries. However, the barriers utilizing these technologies interpreting resulting data can be daunting for first-time users. We provide an overview a brief primer relevant methods (e.g., whole-genome sequencing, reduced-representation sequence-capture methods, RNA sequencing), as well steps analysis pipelines loci clustering, variant calling,...
Abstract Speciation research—the scientific field focused on understanding the origin and diversity of species—has a long complex history. While relevant to one another, specific goals activities speciation researchers are highly diverse, scattered across collection different perspectives. Thus, our will benefit from efforts bridge findings diverse people who do work. In this paper, we outline two ways integrating research: (i) integration, through bringing together ideas, data, approaches;...
Patterns of diversity and turnover in macroorganism communities can often be predicted from differences habitat, phylogenetic relationships among species the geographical scale comparisons. In this study, we asked whether these factors also predict parasite communities. We studied avian malaria two sympatric, ecologically similar, congeneric host at three different sites. prevalence community structure varied with population, phylogeography or distance. used PCR to screen birds for...
Hybrid zones are geographic regions where isolating barriers between divergent populations challenged by admixture. Identifying factors that facilitate or inhibit hybridization in sympatry can illuminate the processes maintain those reproductive barriers. We analysed patterns of and phenotypic variation across two newly discovered hybrid three subspecies barn swallow (Hirundo rustica). These differ ventral coloration wing length, traits targets sexual natural selection, respectively,...
Abstract Population divergence in geographic isolation is due to a combination of factors. Natural and sexual selection may be important shaping patterns population differentiation, pattern referred as ‘isolation by adaptation’ ( IBA ). can complementary the well‐known distance’ IBD ), which closely related populations (via any evolutionary process) associated with isolation. The barn swallow Hirundo rustica complex comprises six subspecies, where divergent phenotypic differentiation among...
Migratory divides are contact zones between breeding populations with divergent migratory strategies during the nonbreeding season. These locations provide an opportunity to evaluate role of seasonal migration in maintenance reproductive isolation, particularly relationship population structure and features associated distinct strategies. We combine light-level geolocators, genomic sequencing, stable isotopes investigate timing routes individuals on either side a divide coinciding...
Abstract Accounting for historical demographic features is vital many types of evolutionary inferences, including the estimation divergence times between closely related populations. In barn swallow, Hirundo rustica , inferring population sizes and subspecies can shed light on recent co‐evolution this species with humans. Pairwise sequentially Markovian coalescent uncovered growth beginning order one million years ago—which may reflect radiation broader genus—and a more decline....
Abstract Phenotypic differentiation plays an important role in the formation and maintenance of reproductive barriers. In some cases, variation a few key aspects phenotype can promote maintain divergence; hence, identification these traits their associations with patterns genomic divergence is crucial for understanding processes population differentiation. We studied hybridization between alba personata subspecies white wagtail ( Motacilla ), quantified introgression multiple morphological...
ABSTRACT Aim Human activity has reshaped ecological communities for thousands of years. While these activities have typically led to habitat loss, some species successfully exploited human environments. However, the effects long‐term land‐use on distributions such are poorly understood. Here, we investigated how change over last 12,000 years altered a widespread human‐commensal bird, Pacific swallow ( Hirundo tahitica ). Location Southeast Asia, Melanesia. Methods We assessed availability...
Abstract Whereas a rich literature exists for estimating population genetic divergence, metrics of phenotypic trait divergence are lacking, particularly comparing multiple traits among three or more populations. Here, we review and analyze via simulation Hedges’ g, widely used parametric estimate effect size. Our analyses indicate that g is sensitive to combination unequal variances sample sizes populations changes in the scale measurement. We then go on derive explain new, non-parametric...
