Chromosome Evolution in New World Monkeys (Platyrrhini) [PDF]

open access: yes, 2012
During the last decades, New World monkey (NWM, Platyrrhini, Anthropoideae) comparative cytogenetics has shed light on many fundamental aspects of genome organisation and evolution in this fascinating, but also highly endangered group of neotropical ...

Contribution à l’étude de la mobilité de l’hallux et de la phylogénie des primates actuels

open access: yesRevue de Primatologie, 2015
Material and methods: 51 anatomical specimens of non-human primates were dissected (18 embalmed, 33 fresh). The amplitudes of the medial cuneometatarsal and metatarsophalangeal articulations of the first ray of the foot of the various fresh pieces and ...

Long-term consistency of spatial patterns of primate seed dispersal [PDF]

open access: yes, 2017
Seed dispersal is a key ecological process in tropical forests, with effects on various levels ranging from plant reproductive success to the carbon storage potential of tropical rainforests.

Phenotypic evolution in marmoset and tamarin monkeys (Cebidae, Callitrichinae) and a revised genus-level classification

open access: yesMolecular Phylogenetics and Evolution, 2018
Marmosets and tamarins (Cebidae, Callitrichinae) constitute the most species-rich subfamily of New World monkeys and one of the most diverse phenotypically. Despite the profusion of molecular phylogenies of the group, the evolution of phenotypic characters under the rapidly-emerging consensual phylogeny of the subfamily has been little studied ...

Effects of reduced-impact logging on medium and large-bodied forest vertebrates in eastern Amazonia [PDF]

open access: yes, 2015
Standard line-transect census techniques were deployed to generate a checklist and quantify the abundance of medium and large-bodied vertebrate species in forest areas of eastern Amazonia with and without a history of reduced-impact logging (RIL).

Assessing the Determinants of Platyrrhine Quadrupedal Gait Kinematics in an Ecological and Phylogenetic Framework

open access: yesAmerican Journal of Primatology, Volume 87, Issue 2, February 2025.
Results of redundancy analysis and variation partitioning reveal that phylogeny influences quadrupedal kinematics more strongly than do substrate characteristics in platyrrhines moving in their natural habitat. Callitrichines are maximally divergent from other taxa due to their preference for asymmetrical gaits, higher speeds and higher stride ...

W(h)ither Fossils? Studying Morphological Character Evolution in the Age of Molecular Sequences [PDF]

open access: yes, 2008
A major challenge in the post-genomics era will be to integrate molecular sequence data from extant organisms with morphological data from fossil and extant taxa into a single, coherent picture of phylogenetic relationships; only then will these ...

The impact of exhibit type on behaviour of caged and free-ranging tamarins [PDF]

open access: yes, 2017
The lack of appropriate stimuli associated with captive environments has been documented to cause several behavioural and physiological issues in captive species, including loss of natural behaviours, psychopathologies and decreased reproductive success.
