Data from: Phylogeographic and population genetic analyses reveal Pleistocene isolation followed by high gene flow in a wide- ranging, but endangered, freshwater mussel

Kentaro Inoue, Emy M. Monroe, Curt L. Elderkin & David J. Berg
Freshwater organisms of North America have had their contemporary genetic structure shaped by vicariant events, especially Pleistocene glaciations. Life history traits promoting dispersal and gene flow continue to shape population genetic structure. Cumberlandia monodonta, a widespread but imperiled (IUCN listed as endangered) freshwater mussel, was examined to determine genetic diversity and population genetic structure range-wide. MtDNA sequences and microsatellite loci were used to measure genetic diversity and simulate demographic events during the Pleistocene using approximate...

Data from: Ecological speciation in anemone-associated snapping shrimps (Alpheus armatus species complex)

Carla Hurt, Katie Silliman, Arthur Anker & Nancy Knowlton
Divergent natural selection driven by competition for limited resources can promote speciation, even in the presence of gene flow. Reproductive isolation is more likely to result from divergent selection when the partitioned resource is closely linked to mating. Obligate symbiosis and host fidelity (mating on or near the host) can provide this link, creating ideal conditions for speciation in the absence of physical barriers to dispersal. Symbiotic organisms often experience competition for hosts, and host...

Mohammed, Andrew C. Baker, Pargol G. Mostafavi … & Chaolun A. Chen
Stylophora pistillata is a widely used coral “lab-rat” species with highly variable morphology and a broad biogeographic range (Red Sea to western central Pacific). Here we show, by analysing Cytochorme Oxidase I sequences, from 241 samples across this range, that this taxon in fact comprises four deeply divergent clades corresponding to the Pacific-Western Australia, Chagos-Madagascar-South Africa, Gulf of Aden-Zanzibar- Madagascar, and Red Sea-Persian/Arabian Gulf-Kenya. On the basis of the fossil record of Stylophora, these four...

Data from: Diversification across the New World within the ‘blue’ cardinalids (Aves: Cardinalidae)

Aim: To examine the history of diversification of ‘blue’ cardinalids (Cardinalidae) across North and South America. Location: North America (including Middle America) and South America. Methods: We collected 163 individuals of the 14 species of blue cardinalids and generated multilocus sequence data (3193 base pairs from one mitochondrial and three nuclear genes) to infer phylogeographical structure and reconstruct time-calibrated species trees. We then estimated the ancestral range at each divergence event and tested for temporal...

Data from: How climate extremes—not means—define a species' geographic range boundary via a demographic tipping point

Heather J. Lynch, Marc Rhainds, Justin M. Calabrese, Stephen Cantrell, Chris Cosner & William F. Fagan
Species’ geographic range limits interest biologists and resource managers alike; however, scientists lack strong mechanistic understanding of the factors that set geographic range limits in the field, especially for animals. There exists a clear need for detailed case studies that link mechanisms to spatial dynamics and boundaries because such mechanisms allow us to predict whether climate change is likely to change a species’ geographic range and, if so, how abundance in marginal populations compares to...

Data from: Vectored dispersal of Symbiodinium by larvae of a Caribbean gorgonian octocoral

Herman H. Wirshing, Kevin Feldheim, Andrew Baker, Kevin A. Feldheim & Andrew C. Baker
The ability of coral reefs to recover from natural and anthropogenic disturbance is difficult to predict, in part due to uncertainty regarding the dispersal capabilities and connectivity of their reef inhabitants. We developed microsatellite markers for the broadcast spawning gorgonian octocoral Eunicea (Plexaura) flexuosa (four markers) and its dinoflagellate symbiont, Symbiodinium B1 (five markers), and used them to assess genetic connectivity, specificity and directionality of gene flow among sites in Florida, Panama, Saba and the...

Data from: Landscape models for nuclear genetic diversity and genetic structure in white-footed mice (Peromyscus leucopus)

Zachary S. Taylor & Susan M. G. Hoffman
Dramatic changes in the North American landscape over the last 12 000 years have shaped the genomes of the small mammals, such as the white-footed mouse (Peromyscus leucopus), which currently inhabit the region. However, very recent interactions of populations with each other and the environment are expected to leave the most pronounced signature on rapidly evolving nuclear microsatellite loci. We analyzed landscape characteristics and microsatellite markers of P. leucopus populations along a transect from southern...
