Food transfers to young and mates in wild owl monkeys (Aotus azarai)

Article Abstract:

The analysis of five groups of socially monogamous owl monkeys (Aotus azarai azarai) in Formosa, Argentina, to elucidate the food sharing trends under natural conditions is described. The findings indicate towards an extremely unique kind of food sharing among animals which are likely to be socially advantageous to monogamous mammals with paternal care.

Comparative chromosome painting in Aotus reveals a highly derived evolution

Article Abstract:

A description on the most likely pattern of chromosome evolution and phylogenetic position of two Aotus karyomorphs (KMs) from 'Venezuela: Aotus nancymai' and 'Aotus sp.' is presented. In addition, chromosome rearrangements between both KMs and the direction of chromosomal evolution in Aotus are discussed.
