Data from: Breakdown of phylogenetic signal: a survey of microsatellite densities in 454 shotgun sequences from 154 non model eukaryote species

Emese Meglécz, Gabriel Nève, Ed Biffin & Michael G. Gardner
Microsatellites are ubiquitous in Eukaryotic genomes. A more complete understanding of their origin and spread can be gained from a comparison of their distribution within a phylogenetic context. Although information for model species is accumulating rapidly, it is insufficient due to a lack of species depth, thus intragroup variation is necessarily ignored. As such, apparent differences between groups may be overinflated and generalizations cannot be inferred until an analysis of the variation that exists within...

Data from: Elevated HIV prevalence and risk behaviors among men who have sex with men (MSM) in Vietnam: a systematic review

Macarena García, Samantha Meyer & Paul Ward
Objectives: To review and analyze original studies on HIV prevalence and risk behaviours among men who have sex with men (MSM) in Vietnam. Design: Systematic literature review. Comprehensive identification of material was conducted by systematic electronic searches of selected databases. Inclusion criteria included studies conducted from 2002 onwards, following a systematic review concluding in 2001 conducted by Colby, Nghia Huu, and Doussantousse. Data analysis was undertaken through the application of both the Cochrane Collaboration and...

Data from: Hybridization of Southern Hemisphere blue whale subspecies and a sympatric area off Antarctica: impacts of whaling or climate change?

Catherine R. M. Attard, Luciano B. Beheregaray, K. Curt S. Jenner, Peter C. Gill, Micheline- N. Jenner, Margaret G. Morrice, Kelly M. Robertson & Luciana M. Möller
Understanding the degree of genetic exchange between subspecies and populations is vital for the appropriate management of endangered species. Blue whales (Balaenoptera musculus) have two recognized Southern Hemisphere subspecies that show differences in geographic distribution, morphology, vocalizations and genetics. During the austral summer feeding season the pygmy blue whale (B. m. brevicauda) is found in temperate waters and the Antarctic blue whale (B. m. intermedia) in polar waters. Here we used genetic analyses to report...

Data from: Social networks and the spread of Salmonella in a sleepy lizard population

C. Michael Bull, Stephanie S. Godfrey & David M. Gordon
Although theoretical models consider social networks as pathways for disease transmission, strong empirical support, particularly for indirectly transmitted parasites, is lacking for many wildlife populations. We found multiple genetic strains of the enteric bacterium Salmonella enterica within a population of Australian sleepy lizards (Tiliqua rugosa), and we found that pairs of lizards that shared bacterial genotypes were more strongly connected in the social network than were pairs of lizards that did not. In contrast there...

Data from: Species tree of a recent radiation: the subfamily Delphininae (Cetacea, Mammalia)

Ana R. Amaral, Jennifer A. Jackson, Luciana M. Moller, Luciano B. Behergaray, Maria M. Coelho, Luciano B. Beheregaray & M. Manuela Coelho
Lineages undergoing rapid radiations provide exceptional opportunities for studying speciation and adaptation, but also represent a challenge for molecular systematics because retention of ancestral polymorphisms and the occurrence of hybridization can obscure relationships among lineages. Dolphins in the subfamily Delphininae are one such case. Non-monophyly, rapid speciation events, and discordance between morphological and molecular characters have made the inference of phylogenetic relationships within this subfamily very difficult. Here we approach this problem by applying multiple...

Data from: Panmixia supports divergence with gene flow in Darwin’s small ground finch, Geospiza fuliginosa, on Santa Cruz, Galápagos Islands

Toby H. Galligan, Stephen C. Donnellan, Frank J. Sulloway, Alison J. Fitch, Terry Bertozzi & Sonia Kleindorfer
The divergence-with-gene-flow model of speciation has a strong theoretical basis with a growing number of plausible examples in nature, but remains hotly debated. Darwin’s finches of the Galápagos Archipelago have played an important role in our understanding of speciation processes. Recent studies suggest that this group may also provide insights into speciation via divergence with gene flow. On the island of Santa Cruz, recent studies found evidence for adaptive divergence in Darwin’s small ground finch,...

Data from: Influences of past climatic changes on historical population structure and demography of a cosmopolitan marine predator, the common dolphin (genus Delphinus)

Ana Amaral, Luciano Beheregaray, Kerstin Bilgmann, Luís Freitas, Kelly Robertson, Marina Sequeira, Karen Stockin, M. M. Coelho & Luciana Möller
Climatic oscillations during the Pleistocene have greatly influenced the distribution and connectivity of many organisms, leading to extinctions but also generating biodiversity. While the effects of such changes have been extensively studied in the terrestrial environment, studies focusing on the marine realm are still scarce. Here we used sequence data from one mitochondrial and five nuclear loci to assess the potential influence of Pleistocene climatic changes on the phylogeography and demographic history of a cosmopolitan...
