Primates [PDF]

open access: yesCurrent Biology, 2012
SummaryHomo sapiens is just one of some 400 extant species allocated to the mammalian order Primates, originally proposed by Linnaeus in the mid-18th Century. As George Gaylord Simpson tartly noted in his seminal 1945 classification of the class Mammalia: “The primates are inevitably the most interesting of mammals to an egocentric species that belongs

Parent-offspring turn-taking dynamics influence parents’ song structure and elaboration in a singing primate

open access: yesFrontiers in Ecology and Evolution, 2022
Parent-offspring interactions are essential to interpret animal social evolution and behavior, but their role in mediating acoustic communication in animals that interact vocally is still unclear.

Long-Term Spatial Restriction Generates Deferred Limited Space Use in a Zoo-Housed Chimpanzee Group

open access: yesAnimals, 2022
Background: Appropriate space is considered paramount for good captive animal welfare. There has been a concerted effort by captive institutions, particularly zoos, to provide captive animals with relatively large, naturalistic enclosures which havehad ...

Species-Specific miRNAs in Human Brain Development and Disease

open access: yesFrontiers in Cellular Neuroscience, 2019
Identification of the unique features of human brain development and function can be critical towards the elucidation of intricate processes such as higher cognitive functions and human-specific pathologies like neuropsychiatric and behavioral disorders.

Quantitative uniqueness of human brain evolution revealed through phylogenetic comparative analysis

open access: yeseLife, 2019
While the human brain is clearly large relative to body size, less is known about the timing of brain and brain component expansion within primates and the relative magnitude of volumetric increases.

Primate neuronal connections are sparse in cortex as compared to mouse

open access: yesCell Reports, 2021
Summary: Detailing how primate and mouse neurons differ is critical for creating generalized models of how neurons process information. We reconstruct 15,748 synapses in adult Rhesus macaques and mice and ask how connectivity differs on identified cell ...

Radioimmunoassay of human plasma Lp(a) lipoprotein

open access: yesJournal of Lipid Research, 1977
A quantitative immunodiffusion assay demonstrated Lp(a) lipoprotein in 91% (911 of 1000) of subjects. In order to quantitate Lp(a) in all plasma, a sensitive and specific double antibody radioimmunoassay was developed.

Le jeu des illusions : discrimination entre apparence et réalité chez les primates

open access: yesRevue de Primatologie, 2020
Perception is an essential process to gather information about our physical and social environment, and thus to adjust our behaviour to environmental changes. However, we are confronted every day with ambiguous situations in which things appear different

Effects of Enclosure and Environmental Enrichment on the Behaviour of Ring-Tailed Lemurs (Lemur catta)

open access: yesJournal of Zoological and Botanical Gardens, 2021
Environmental enrichment is widely used to improve the quality of life of animals under human care. To successfully implement enrichment programs, it is important to evaluate their effect in different enclosure types since housing conditions may change ...
