Enhancing fish diet analysis: equations to reconstruct Themisto gaudichaudii and Euphausia lucens length from partially digested remains
(Taylor & Francis As, 2013-03)
Themisto gaudichaudii and Euphausia lucens are important prey of several fish and squid species of commercial value in the southwest Atlantic Ocean. Although allometric relationships linking size and weight can be used to ...
Phenotypic plasticity and the colonization of new habitats: a study of a colonial spider in the Chaco region and the Cerrado
(Springer, 2021-02)
In social animals, group prey capture could facilitate colonization of new areas with low resource availability. Parawixia bistriata is a colonial spider inhabiting seasonal dry forests and mesic habitats in South America. ...
Paleoecology of the mammalian predator guild of Southern Patagonia during the latest Pleistocene: Ecomorphology, stable isotopes, and taphonomy
(Pergamon-Elsevier Science Ltd, 2013-08)
During the late Pleistocene, Patagonia had a rich fauna of large mammals including some megamammals such as ground sloths (Mylodon darwini), horse (Hippidion saldiasi), and camelids (e.g., Lama guanicoe). The carnivore ...
Diversity and evolution of macrohabitat use, body size and morphology in a monophyletic group of Neotropical pitvipers (Bothrops)
(Cambridge University Press, 2001-08-01)
The Neotropical pitviper genus Bothrops comprises about 40 species, which occur in all main ecosystems of cis-Andean South America. We explored the relationships of body size and form (tail length and stoutness) with ...

Morpho-functional analysis of the mastoid region of the extinct South American mustelid †Stipanicicia pettorutii
(Royal Society of Edinburgh, 2017-02-06)
The morphology of the mastoid region in predators is informative about the hunting strategies and capacity of carrying prey. The purpose of this research was to describe the mastoid region and reconstruct the associated ...

El objetivo de este trabajo fue evaluar la dieta del Chorlito Doble Collar (Charadrius falklandicus) en Playa Colombo (Golfo Nuevo, Península Valdés) y compararla con la registrada previamente en Playa Fracasso (Golfo San ...
Isotopic niche partitioning between two apex predators over time
(Wiley Blackwell Publishing, Inc, 2017-03)
1. Stable isotope analyses have become an important tool in reconstructing diets, analyzing resource use patterns, elucidating trophic relations among predators and understanding the structure of food webs.<br />2. Here, ...
