Gustatory responses in primates to the sweetener aspartame and their phylogenetic implications [PDF]

, 2017
Two-bottle preference tests have been applied to 70 (sub-) species of the order of Primates and, for comparison, to the tree shrew (Tupaia belangeri) to determine their responses to aspartame (APM), the first known sweet-tasting dipeptide which has to ...

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

, 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

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

American 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

Audience effects in sooty mangabey agonistic behavior

Frontiers in Psychology
The term ‘Audience Effects’, refers to behavioral changes triggered by the mere presence of others and has been extensively studied in animals to explore their capacity for social awareness and intentionality.

Bystanders, parcelling, and an absence of trust in the grooming interactions of wild male chimpanzees [PDF]

, 2016
The evolution of cooperation remains a central issue in socio-biology with the fundamental problem of how individuals minimize the risks of being short-changed (‘cheated’) should their behavioural investment in another not be returned. Economic decisions

Same data, different results? Machine learning approaches in bioacoustics

Methods in Ecology and Evolution, Volume 16, Issue 8, Page 1574-1586, August 2025.
Abstract Automated acoustic analysis is increasingly used in behavioural ecology, and determining caller identity is a key element for many investigations. However, variability in feature extraction and classification methods limits the comparability of results across species and studies, constraining conclusions we can draw about the ecology and ...

Aids – ein Unfall der viralen Evolution? : Warum das Immunsystem infizierter Affen nicht zerstört wird ; Nachwuchspreis für Michael Schindler [PDF]

, 2007
Warum das humane Immundefizienzvirus Typ 1 (HIV-1) im Menschen Aids hervorruft, während nahe verwandte Affen-Immundefizienzviren (SIV »Simian Immunodeficiency Virus«) ihre natürlichen Affenwirte nicht krank machen, war lange Zeit nicht zu erklären.

Allometry and phylogenetic divergence: Correspondence or incongruence?

The Anatomical Record, Volume 308, Issue 3, Page 868-891, March 2025.
Abstract The potential connection between trends of within species variation, such as those of allometric change in morphology, and phylogenetic divergence has been a central topic in evolutionary biology for more than a century, including in the context of human evolution. In this study, I focus on size‐related shape change in craniofacial proportions

Glycosylation of the envelope glycoprotein gp130 of simian immunodeficiency virus from sooty mangabey (Cercocebus atys) [PDF]

Biochemical Journal, 1990
The envelope glycoprotein 130 (‘130’ referring to an Mr of 130,000) of simian immunodeficiency virus from sooty mangabey (Cercocebus atys) (SIVSM) was isolated from the cell-free supernatant of the SIVSM-infected human T-cell line H9, metabolically labelled with D-[6-3H]glucosamine.
