TL;DR: Considering molecular, morphological and biogeographic evidence, a new genus level taxonomy for titi monkeys is proposed: Cheracebus n.

TL;DR: This evolutionary history is most consistent with a Young Amazon Flooded Forest Taxa model, suggesting Saimiri has always maintained a lowland wetlands niche and was able to greatly expand its range with the transition from a lacustrine to a riverine system in Amazonia.

TL;DR: The rate of natural Plasmodium infection in monkeys in the Brazilian state of Rondônia is in line with previous surveys of simian malaria in the Amazon region and the fact that a monkey species was found that had not previously been described to harbour malaria parasites indicates that these animals can act as reservoirs of human malaria.

TL;DR: Overall, a high frequency of terrestrial behavior in titi monkeys is found, unlike that observed in other pitheciids, and may bolster resistance to habitat fragmentation.

TL;DR: The results corroborated previous studies suggesting that the species of the current C. personatus group form a distinct species group and indicate that the relationships among groups and species may still not be completely understood, highlighting the need for further research into the biological, geographic, and genetic variability of these primates.
