History of canids in Chile and impacts on prey adaptations. [PDF]
Ecol Evol, 2021 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]
Ecol Evol, 2019 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]
Ecol EvolReconstructing 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?
Geo: Geography and Environment, Volume 9, Issue 2, July‐December 2022., 2022 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

South American giant short-faced bear (Arctotherium angustidens) diet: evidence from pathology, morphology, stable isotopes, and biomechanics [PDF]
Journal of Paleontology, 2014 Arctotherium angustidensGervais and Ameghino, 1880 (the South American giant short-faced bear) is known for being the earliest (Ensenadan Age, early to middle Pleistocene) and largest (body mass over 1 ton) of five describedArctotheriumspecies endemic to South America. Here we assess the diet of this bear from multiple proxies: morphology, biomechanics,

First report of a South American short-faced bears' den (Arctotherium angustidens): palaeobiological and palaeoecological implications [PDF]
Alcheringa: An Australasian Journal of Palaeontology, 2009 Here we report the first example of associated short-faced bear fossils from South America. The specimens represent three individuals referable to the Ensenadan (early to middle Pleistocene) species Arctotherium angustidens (Ursidae, Tremarctinae), the giant South American short-faced bear.

Anatomical study of the auditory region of Arctotherium tarijense (Ursidae, Tremarctinae), an extinct short‐faced bear from the Pleistocene of South America [PDF]
Journal of Anatomy, 2016 AbstractHere we present the most detailed morphological study of the auditory region of a tremarctinae bear, Arctotherium tarijense Ameghino. In addition, we provide new anatomical information of the Tremarctinae inner ear, such as coplanarity and deviation from orthogonality of the semicircular canals, as an approach to infer the head movements which ...

Late Pleistocene carnivores (Carnivora: Mammalia) from a cave sedimentary deposit in northern Brazil
Anais da Academia Brasileira de Ciências, 2014 The Brazilian Quaternary terrestrial Carnivora are represented by the following families: Canidae, Felidae, Ursidae, Procyonidae Mephitidae and Mustelidae. Their recent evolutionary history in South America is associated with the uplift of the Panamanian
