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.

Simplified Communities of Seed-Dispersers Limit the Composition and Flow of Seeds in Edge Habitats

open access: yesFrontiers in Ecology and Evolution, 2021
Edge effects, driven by human modification of landscapes, can have critical impacts on ecological processes such as species interactions, with cascading impacts on biodiversity as a whole. Characterizing how edges affect vital biotic interactions such as

Cellular events of acute, resolving or progressive COVID-19 in SARS-CoV-2 infected non-human primates

open access: yesNature Communications, 2020
Here, Fahlberg et al. describe the cellular immune response during acute, resolving or progressive COVID-19 in SARS-CoV-2 infected non-human primates. The study identifies associations of monocytes and macrophage subtypes in lungs with disease outcome ...

The hemodynamic initial-dip consists of both volumetric and oxymetric changes reflecting localized spiking activity

open access: yesFrontiers in Neuroscience, 2023
The initial-dip is a transient decrease frequently observed in functional neuroimaging signals, immediately after stimulus onset, believed to originate from a rise in deoxy-hemoglobin (HbR) caused by local neural activity.

Monkey metacognition could generate more insight [PDF]

open access: yesAnimal Behavior and Cognition, 2019
Monkeys demonstrate metacognition by avoiding memory tests when they forget, seeking information when ignorant, and gambling sensibly after making judgments. Some of this metacognition appears to be based on introspection of private mental states.

Primates chunk simultaneously-presented memoranda

open access: yesFrontiers in Behavioral Neuroscience, 2022
Though much research has characterized both the behavior and electrophysiology of spatial memory for single targets in non-human primates, we know much less about how multiple memoranda are handled. Multiple memoranda may interact in the brain, affecting

Encoding conditions affect recognition of vocally expressed emotions across cultures

open access: yesFrontiers in Psychology, 2013
Although the expression of emotions in humans is considered to be largely universal, cultural effects contribute to both emotion expression and recognition.

Conserved presence of G-quadruplex forming sequences in the Long Terminal Repeat Promoter of Lentiviruses [PDF]

open access: yes, 2017
G-quadruplexes (G4s) are secondary structures of nucleic acids that epigenetically regulate cellular processes. In the human immunodeficiency lentivirus 1 (HIV-1), dynamic G4s are located in the unique viral LTR promoter.

La visite au zoo et l’apprentissage de la distinction humaine

open access: yesRevue d'anthropologie des connaissances, 2012
The zoo might be regarded as a cultural device that structures the relationships between human beings and captive animals. In this study we searched to identify the patterns that connect visitors and captive animals during the zoo visit experience.
