Data from: Extinction and recolonization of maritime Antarctica in the limpet Nacella concinna (Strebel, 1908) during the last glacial cycle: toward a model of Quaternary biogeography in shallow Antarctic invertebrates

Claudio A. González-Wevar, Thomas Saucède, Simon A. Morley, Steven L. Chown & Elie Poulin
Quaternary glaciations in Antarctica drastically modified geographical ranges and population sizes of marine benthic invertebrates and thus affected the amount and distribution of intraspecific genetic variation. Here, we present new genetic information in the Antarctic limpet Nacella concinna, a dominant Antarctic benthic species along shallow ice-free rocky ecosystems. We examined the patterns of genetic diversity and structure in this broadcast spawner along maritime Antarctica and from the peri-Antarctic island of South Georgia. Genetic analyses showed...

Data from: Unveiling current guanaco distribution in Chile based upon niche structure of phylogeographic lineages: Andean puna to subpolar forests

Benito A. González, Horacio Samaniego, Juan Carlos Marín & Cristián F. Estades
Niche description and differentiation at broad geographic scales have been recent major topics in ecology and evolution. Describing the environmental niche structure of sister taxa with known evolutionary trajectories stands out as a useful exercise in understanding niche requirements. Here we model the environmental niche structure and distribution of the recently resolved phylogeography of guanaco (Lama guanicoe) lineages on the western slope of the southern Andes. Using a maximum entropy framework, field data, and information...

Data from: Evidence for non-allopatric speciation among closely related sympatric Heliotropium species in the Atacama Desert

Federico Luebert, Pit Jacobs, Hartmut H. Hilger & Ludo A. H. Muller
The genetic structure of populations of closely related, sympatric species may hold the signature of the geographical mode of the speciation process. In fully allopatric speciation, it is expected that genetic differentiation between species is homogeneously distributed across the genome. In non-allopatric speciation, the genomes may remain undifferentiated to a large extent. In this paper, we analysed the genetic structure of five sympatric species from the plant genus Heliotropium in the Atacama Desert. We used...

Data from: Phylogeography and population history of Leopardus guigna, the smallest American felid

Constanza Napolitano, Warren E. Johnson, Jim Sanderson, Stephen J. O'Brien, Rus Hoelzel, Rachel Freer, Nigel Dunstone, Kermit Ritland, Carol E. Ritland, Elie Poulin & A. Rus Hoelzel
The guigna (Leopardus guigna) is the smallest and most-restricted New World cat species, inhabiting only around 160,000 km2 of temperate rain forests in southern South America and is currently threatened by habitat loss, fragmentation and human persecution. We investigated phylogeographic patterns of genetic diversity, demographic history and barriers to gene flow with 116 individuals sampled across the species geographic range by analyzing 1,798 base pairs of the mtDNA (496 bp HVSI region, 720 bp NADH-5...
