Functional New World monkey oxytocin forms elicit an altered signaling profile and promotes parental care in rats
Significance Several forms of the oxytocin neurohormone have been found in New World monkeys (NWMs). Previous research has suggested an association between these forms and behaviors typical of thisExpand

Larval feeding choices in heliconians: induced preferences are not constrained by performance and host plant phylogeny
Induction of feeding preference, a special type of learning found in the larval stage of herbivorous insects, may be a link between evolutionary changes in host selection behaviour, variation in dietExpand

Phylogenetic and morphological relationships between nonvolant small mammals reveal assembly processes at different spatial scales
The relative roles of historical processes, environmental filtering, and ecological interactions in the organization of species assemblages vary depending on the spatial scale. We evaluated theExpand

Identification of the e allele at the Extension locus (MC1R) in Brazilian Creole sheep and its role in wool color variation.
The melanocortin 1 receptor (MC1R) gene has been described as responsible for the black color in some breeds of sheep, but little is known about its function in many colored breeds, particularlyExpand

Sequence variation in the melanocortin-1 receptor (MC1R) pigmentation gene and its role in the cryptic coloration of two South American sand lizards
In reptiles, dorsal body darkness often varies with substrate color or temperature environment, and is generally presumed to be an adaptation for crypsis or thermoregulation. However, the geneticExpand

Mitochondrial and nuclear DNA analyses reveal population differentiation in Brazilian Creole sheep.
Using ND5 sequences from mtDNA and 10 nuclear markers, we investigated the genetic differentiation of two South American Creole sheep phenotypes that historically have been bred in different biomesExpand
