Data from: Influence of drift and admixture on population structure of American black bears (Ursus americanus) in the Central Interior Highlands, U.S.A. 50 years after translocation

Bottlenecks, founder events, and genetic drift often result in decreased genetic diversity and increased population differentiation. These events may follow abundance declines due to natural or anthropogenic perturbations, where translocations may be an effective conservation strategy to increase population size. American black bears (Ursus americanus) were nearly extirpated from the Central Interior Highlands, USA by 1920. In an effort to restore bears, 254 individuals were translocated from Minnesota, USA and Manitoba, Canada, into the Ouachita...

Data from: Effect of microsatellite selection on individual and population genetic inferences: an empirical study using cross-specific and species-specific amplifications

Joao Queiros, Raquel Godinho, Susana Lopes, Christian Gortazar, Jose De La Fuente & Paulo C. Alves
Although whole-genome sequencing is becoming more accessible and feasible for nonmodel organisms, microsatellites have remained the markers of choice for various population and conservation genetic studies. However, the criteria for choosing microsatellites are still controversial due to ascertainment bias that may be introduced into the genetic inference. An empirical study of red deer (Cervus elaphus) populations, in which cross-specific and species-specific microsatellites developed through pyrosequencing of enriched libraries, was performed for this study. Two different...

Data from: Selection from parasites favors immunogenetic diversity but not divergence among locally adapted host populations

The unprecedented polymorphism in the major histocompatibility complex (MHC) genes is thought to be maintained by balancing selection from parasites. However, do parasites also drive divergence at MHC loci between host populations, or do the effects of balancing selection maintain similarities among populations? We examined MHC variation in populations of the livebearing fish Poecilia mexicana and characterized their parasite communities. Poecilia mexicana populations in the Cueva del Azufre system are locally adapted to darkness and...

Data from: Experimentally decoupling reproductive investment from energy storage to test the functional basis of a life-history tradeoff

Robert M. Cox, Matthew B. Lovern & Ryan Calsbeek
The ubiquitous life-history trade-off between reproduction and survival has long been hypothesized to reflect underlying energy-allocation trade-offs between reproductive investment and processes related to self-maintenance. Although recent work has questioned whether energy-allocation models provide sufficient explanations for the survival cost of reproduction, direct tests of this hypothesis are rare, especially in wild populations. This hypothesis was tested in a wild population of brown anole lizards (Anolis sagrei) using a two-step experiment. First, stepwise variation in...

Data from: Worldwide patterns of ancestry, divergence, and admixture in domesticated cattle

The domestication and development of cattle has considerably impacted human societies, but the histories of cattle breeds have been poorly understood especially for African, Asian, and American breeds. Using genotypes from 43,043 autosomal single nucleotide polymorphism markers scored in 1,543 animals, we evaluate the population structure of 134 domesticated bovid breeds. Regardless of the analytical method or sample subset, the three major groups of Asian indicine, Eurasian taurine, and African taurine were consistently observed. Patterns...

Data from: \"Transcriptome sequence identity between Lyme disease tick vectors, Ixodes scapularis and Ixodes ricinus\" in Genomic Resources Notes accepted 1 April 2014 to 31 May 2014

Marinela Contreras, Raquel Tobes, Libor Grubhoffer, Agustin Estrada-Peña & Jose De La Fuente
Ixodes scapularis and I. ricinus transmit the Lyme disease agent Borrelia burgdorferi in the U.S. and Europe, respectively. The only tick genome sequence available is that of I. scapularis, which constitutes a limitation for tick research. Recent evidences suggest that I. ricinus and I. scapularis transcriptomes share some degree of sequence identity. However, only the global transcriptome comparison reported here demonstrated that I. ricinus and I. scapularis share a 99.232±0.005 percent sequence identity with a...

Data from: Evolution of body shape in differently colored sympatric congeners and allopatric populations of Lake Malawi’s rock-dwelling cichlids

Martin Husemann, Michael Tobler, Cagney McCauley, Baoqing Ding & Patrick D. Danley
The cichlid fishes of Lake Malawi represent one of the most diverse adaptive radiations of vertebrates known. Among the rock-dwelling cichlids (mbuna), closely related sympatric congeners possess similar trophic morphologies (i.e. cranial and jaw structures), defend overlapping or adjacent territories, but can be easily distinguished based on male nuptial coloration. The apparent morphological similarity of congeners, however, leads to an ecological conundrum: theory predicts that ecological competition should lead to competitive exclusion. Hence, we hypothesized...
