History of canids in Chile and impacts on prey adaptations. [PDF]
South American artiodactyls seem to be highly susceptible to feral dog predation, presenting a major conservation threat—why? We synthesize evidence as to whether feral dogs represent the first group‐hunting cursorial predator in regional evolutionary history.

Ecology of a widespread large omnivore, Homo sapiens, and its impacts on ecosystem processes. [PDF]
The ecology of humans is usually considered separately and often using different concepts to those used for other species. We propose an ecological approach to humans based on the joint consideration of intraspecific variation and interspecific comparison.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals. [PDF]
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?
A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search

Here we present the first detailed morphological study of the auditory region of a tremarctine bear, the South American giant short-faced bear Arctotherium angustidens. We compared 19 specimens of A. angustidens with other tremarctines and ursines.

The Southernmost bear: Pararctotherium (Carnivora, Ursidae, Tremarctinae) in the latest Pleistocene of Southern Patagonia, Chile [PDF]
A second upper incisor belonging to the tremarctine bear Pararctotherium was recovered from latest Pleistocene deposits in Cueva de los Chingues, Magallanes, Chile (San Roman et al., 2000). This is the southernmost record of an ursid in the world and one

Spectroscopic Characterization of Eoholocene Bones Found in a Cave in Northeast Brazil
The preservation of fossils depends on several interactions of organic and inorganic chemical processes. The hard parts, which are more suitable for fossilization, might record valuable information of biogenic processes, while the taphonomic characteristics supply information on postmortem chemical transformation.

Infomap Bioregions: Interactive mapping of biogeographical regions from species distributions [PDF]
Biogeographical regions (bioregions) reveal how different sets of species are spatially grouped and therefore are important units for conservation, historical biogeography, ecology and evolution. Several methods have been developed to identify bioregions
