The formation of the Isthmus of Panama stands as one of the greatest natural events of the
Cenozoic, driving profound biotic transformations on land and in the oceans. Some recent …

Small carnivores–here defined as members of the mammalian order Carnivora with a body
mass< 21.5 kg–occur worldwide, including in Oceania, following introductions. They are …

Four species of spotted skunks (Carnivora, Mephitidae, Spilogale) are currently recognized:
Spilogale angustifrons, S. gracilis, S. putorius, and S. pygmaea. Understanding species …

Genetic diversity is crucial for conservation biology and for understanding evolutionary
processes. Oceanic islands harbor a unique biota and high endemism, with populations …

Successful species introductions are not homogeneously distributed over the globe, which
points to the need to understand why some have succeeded, yet others failed. We …

Islands host exceptionally high levels of endemism compared to mainland regions and are
subject to disproportionately high rates of extinction and imperilment. Therefore, the …

The genetic structure of the Asiatic black bear (Ursus thibetanus) in Japan was studied to
understand the events that occurred during its evolution. The left domain of the …

White-nosed coatis (Nasua narica) are widely distributed throughout North, Central, and
South America, but the patterns of temporal and spatial diversification that have contributed …

The introduction of species outside their natural range is one of the major threats to
biodiversity and has often been identified as a menace to agricultural production and human …

Insular dwarfism is common in mammals. Many theories have been put forward to explain it,
including competitive release, predation release, resource limitation and limited dispersal …
