Kin structure and parallel dispersal in the black-and-gold howler monkey Alouatta caraya (Platyrrhini, Atelidae)

open access: yesGenetics and Molecular Research, 2013
We here investigated the kin structure and pattern of dispersal in the black-and-gold howler monkey (Alouatta caraya, Platyrrhini, Atelidae) based on genotype differences at nine microsatellite loci of 48 individuals from eight social groups along the riparian forest of the Tocantins River, Brazil.

Niche differentiation, reproductive interference, and range expansion

open access: yesEcology Letters, Volume 27, Issue 1, January 2024.
Ecological niche models were used to evaluate whether large differences between rubyspot damselfly (Hetaerina) species in geographic range can be explained by niche differentiation. Surprisingly, the species with the largest latitudinal range has one of the narrowest climatic niches.
