Oldest skeleton of a plesiadapiform provides additional evidence for an exclusively arboreal radiation of stem primates in the Palaeocene [PDF]

Royal Society Open Science, 2017
Palaechthonid plesiadapiforms from the Palaeocene of western North America have long been recognized as among the oldest and most primitive euarchontan mammals, a group that includes extant primates, colugos and treeshrews.

The Island of Female Power? Intersexual Dominance Relationships in the Lemurs of Madagascar

Frontiers in Ecology and Evolution, 2022
The extant primates of Madagascar (Lemuriformes) represent the endpoints of an adaptive radiation following a single colonization event more than 50 million years ago. They have since evolved a diversity of life history traits, ecological adaptations and

Learning to Control a Brain–Machine Interface for Reaching and Grasping by Primates

PLoS Biology, 2003
Reaching and grasping in primates depend on the coordination of neural activity in large frontoparietal ensembles. Here we demonstrate that primates can learn to reach and grasp virtual objects by controlling a robot arm through a closed-loop brain ...

Novel insights into the genetic diversity of Balantidium and Balantidium-like cyst-forming ciliates [PDF]

, 2013
Balantidiasis is considered a neglected zoonotic disease with pigs serving as reservoir hosts. However, Balantidium coli has been recorded in many other mammalian species, including primates. Here, we evaluated the genetic diversity of B.

Frecuencia de enteroparásitos en primates Cebidae y Callitrichidae del Zoológico de Cali, Colombia: implicaciones zoonóticas

Biomédica: revista del Instituto Nacional de Salud, 2021
Introducción. Los enteroparásitos pueden generar problemas en animales bajo cuidado humano en zoológicos y centros de acogida. Los animales silvestres presentan bajas cargas parasitarias, pero estas pueden ser mayores y llevar a manifestaciones clínicas ...

Accelerated Evolution of the ASPM Gene Controlling Brain Size Begins Prior to Human Brain Expansion [PDF]

, 2004
Primary microcephaly (MCPH) is a neurodevelopmental disorder characterized by global reduction in cerebral cortical volume. The microcephalic brain has a volume comparable to that of early hominids, raising the possibility that some MCPH genes may have ...

Primates in peril: the significance of Brazil, Madagascar, Indonesia and the Democratic Republic of the Congo for global primate conservation

PeerJ, 2018
Primates occur in 90 countries, but four—Brazil, Madagascar, Indonesia, and the Democratic Republic of the Congo (DRC)—harbor 65% of the world’s primate species (439) and 60% of these primates are Threatened, Endangered, or Critically Endangered (IUCN ...
