Diversity and prevalence of gastrointestinal parasites in seven non-human primates of the Taï National Park, Côte d’Ivoire

open access: yesParasite, 2015
Parasites and infectious diseases are well-known threats to primate populations. The main objective of this study was to provide baseline data on fecal parasites in the cercopithecid monkeys inhabiting Côte d’Ivoire’s Taï National Park.

Range extension, imminent threats and conservation options for two endangered primates: The Tana River Red Colobus Procolobus rufomitratus rufomitratus (Peters, 1879) and the Tana River Mangabey Cercocebus galeritus (Peters, 1879) in the Lower Tana Floodplain and Delta, Kenya [PDF]

open access: yes, 2012
Two Endangered primate taxa, the Tana River red colobus (population estimate less than 1200) and the Tana River mangabey (population estimate less than 2000), are only known from a restricted area of patchy riverine forest in the floodplain of the Lower ...

New Middle Pleistocene Hominin Dental Remains From Velika Balanica, Serbia

open access: yesAmerican Journal of Biological Anthropology, Volume 188, Issue 2, October 2025.
ABSTRACT Objective The cave site of Velika Balanica in Sićevo Gorge, Serbia, has previously yielded early Neanderthal dental remains from Layer 3a, dated by thermoluminescence to 285 ± 34 and 295 ± 74 ka. We describe and compare four additional dental specimens recovered from the Middle Pleistocene Layers 3a and 3b of the cave: a right I1 (BH‐8), a ...

Trade and ethnozoological use of African lorisiformes in the last 20 years [PDF]

open access: yes, 2016
Trade in primates is considered a major impediment to primate conservation globally. The bushmeat trade in West and Central Africa is considered largely unsustainable and represents one of the main threats to biodiversity.

Look past the cooperative eye hypothesis: reconsidering the evolution of human eye appearance

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2038-2054, October 2025.
ABSTRACT The external appearance of the human eye has been prominently linked to the evolution of complex sociocognitive functions in our species. The cooperative eye hypothesis (CEH) proposes that human eyeballs, with their weakly expressed conjunctival and scleral pigmentation, are uniquely conspicuous and evolved under selective pressures to behave ...

Identification of a novel retroviral gene unique to human immunodeficiency virus type 2 and simian immunodeficiency virus SIVMAC [PDF]

open access: yes, 1988
Human and simian immunodeficiency-associated retroviruses are extraordinarily complex, containing at least five genes, tat, art, sor, R, and 3' orf, in addition to the structural genes gag, pol, and env.

Dental Microwear and Diets of Late Miocene Primates From Rudabánya, Hungary

open access: yesAmerican Journal of Biological Anthropology, Volume 188, Issue 1, September 2025.
ABSTRACT Objectives This study focuses on a dental microwear texture analysis of European pliopithecids and dryopithecins from the Miocene primate site of Rudabánya, Hungary. The goal is to determine whether these taxa, found in part together in the same deposits, differed in their food preferences, or at least consumed, on a daily basis, in a manner ...

The Ontogeny of “Twitter” Calls in White‐Faced Capuchins (Cebus imitator): Usage, Context, and Acoustic Structure

open access: yesAmerican Journal of Primatology, Volume 87, Issue 8, August 2025.
ABSTRACT In stark contrast to our own highly plastic communicative abilities, nonhuman primate vocalizations were historically considered fixed and innate, with very little ability to learn or modify vocal signals. However, recent studies indicate that primate vocalizations do show evidence of developmental plasticity, most notably in their context and

Social complexity parallels vocal complexity: a comparison of three nonhuman primate species

open access: yesFrontiers in Psychology, 2013
Social factors play a key role in the structuring of vocal repertoires at the individual level, notably in nonhuman primates. Some authors suggested that, at the species level too, social life may have driven the evolution of communicative complexity ...

Evolution of the POU1F1 transcription factor in mammals: rapid change of the alternatively-spliced β-domain [PDF]

open access: yes, 2018
The POU1F1 (Pit-1) transcription factor is important in regulating expression of growth hormone, prolactin and TSH β-subunit, and controlling development of the anterior pituitary cells in which these hormones are produced. POU1F1 is a conserved protein
