Extreme and remote environments provide useful settings to test ideas about the ecological
and evolutionary drivers of biological diversity. In the sub‐A ntarctic, isolation by geographic …

Aim We assess biogeographical patterns, population structure and the range of species in
the pulmonate genus Siphonaria across the sub‐Antarctic. We hypothesized that locally …

The species of the genus Aequiyoldia Soot-Ryen, 1951, previously known as Yoldia, are
common, soft-substratum, sareptid bivalves. In the Southern Ocean, Aequiyoldia eightsii …

Galaxias species are interesting biogeographic models due to their distribution and different
types of life cycles, with migratory and landlocked populations. To obtain a better …

The southern coastline of South America is a remarkable area to evaluate how Quaternary
glacial processes impacted the demography of the near-shore marine biota. Here we …

The relative importance of genetic drift and local adaptation in facilitating speciation remains
unclear. This is particularly true for seabirds, which can disperse over large geographic …

Burdwood Bank is a shallow seamount located south of the Malvinas (Falkland) Islands and
east of Tierra del Fuego. In 2013, the area down to 200 m depth of this bank was declared …

The rise of the southern Andes and the Quaternary glacial cycles influenced the landscape
of Patagonia, affecting the phylogeographic and biogeographic patterns of its flora and …

True limpets of the genus Nacella (Patellogastropoda: Nacellidae) include at least 11
nominal species distributed in different provinces of the Southern Ocean. Here, we present …

An increase in richness of benthic marine mollusks towards high latitudes has been
described on the Pacific coast of Chile in recent decades. This considerable increase in …
