Unusual intra-individual karyotypical variation and evidence of cryptic species in Amazonian populations of Pristimantis (Anura, Terrarana)
(Wiley-Blackwell, 2009-09-01)
We report a cytogenetic analysis of three Pristimantis fenestratus frog populations of the Amazon region in Brazil. the specimens were sampled in Borba and Manaus, Amazonas State, and in Rio Branco, Acre State. They were ...
Especialização individual no uso de recursos alimentares de Characidium schubarti (Crenuchidae)
(Universidade Estadual Paulista (Unesp), 2019-08-27)
A variação individual no uso de recursos alimentares pode depender de fatores ecológicos como a competição intra e interespecífica, predação, além da diversidade e abundância de recursos. O objetivo deste trabalho foi ...

A framework for studying behavioral evolution by reconstructing ancestral repertoires
(eLife Sciences, 2021-09)
Although different animal species often exhibit extensive variation in many behaviors, typically scientists examine one or a small number of behaviors in any single study. Here, we propose a new framework to simultaneously ...
Intra-specific trophic variation in false killer whales (Pseudorca crassidens) from the southwestern South Atlantic Ocean through stable isotopes analysis
(Elsevier, 2015-01)
The false killer whale (Pseudorca crassidens) is a highly social top predator difficult to study in the wild because of its wide-ranging oceanic habits. Mass strandings offer good opportunities to gather ecological information ...
Holocene (~4.5-1.7 cal. kyr BP) paleoenvironmental conditions in central Argentina inferred from entire-shell and intra-shell stable isotope composition of terrestrial gastropods
(Sage Publications Ltd, 2014-08)
The isotopic fingerprint of terrestrial gastropods has been increasingly used as a credible natural paleoenvironmental archive. Most published work has used this proxy at tropical and temperate latitudes of the Northern ...
