DOI: 10.1002/ajp.22558
Abstract: Immunoglobulin A (IgA) is the primary antibody responsible for mucosal defense in mammals and has been used as a marker for chronic stress and immune status. Therefore, this antibody may provide a more reliable indicator… read more here.

Chimpanzees (Pan troglodytes) tolerate some degree of inequity while cooperating but refuse to donate effort for nothing

DOI: 10.1002/ajp.23084
Abstract: In cooperative hunting, a carcass cannot be divided equally, and hunts may be unsuccessful. We studied how chimpanzees respond to these two variables, working for unequal rewards and no rewards, which have been rarely included… read more here.

Forest fragments become farmland: Dietary Response of wild chimpanzees (Pan troglodytes) to fast‐changing anthropogenic landscapes

DOI: 10.1002/ajp.23090
Abstract: Behavioral flexibility, including an ability to modify feeding behavior, is a key trait enabling primates to survive in forest fragments. In human‐dominated landscapes, unprotected forest fragments can become progressively degraded, and may be cleared entirely,… read more here.

Drinking frequency in wild lactating chimpanzees (Pan troglodytes schweinfurthii) and their offspring

DOI: 10.1002/ajp.23371
Abstract: Maintaining water balance is essential for organismal health, and lactating females must balance individual needs with milk production and offspring hydration. Primate milk is dilute and presumed to be the primary source for infant hydration… read more here.

DOI: 10.1002/ajpa.23478
Abstract: OBJECTIVES We investigated occurrences and patterns of terrestrial nocturnal activity in wild chimpanzees (Pan troglodytes) and modelled the influence of various ecological predictors on nocturnal activity. METHODS Data were extracted from terrestrial camera-trap footage and… read more here.

Chimpanzees (Pan troglodytes) show subtle signs of uncertainty when choices are more difficult

DOI: 10.1016/j.cognition.2021.104766
Abstract: Humans can tell when they find a task difficult. Subtle uncertainty behaviors like changes in motor speed and muscle tension precede and affect these experiences. Theories of animal metacognition likewise stress the importance of endogenous… read more here.

DOI: 10.1126/sciadv.abm4754
Abstract: Almost all animals navigate their environment to find food, shelter, and mates. Spatial cognition of nonhuman primates in large-scale environments is notoriously difficult to study. Field research is ecologically valid, but controlling confounding variables can… read more here.

Chimpanzees (Pan troglodytes) Are More Averse to Social Than Nonsocial Risk
Sign Up to like & getrecommendations! Published in 2019 at "Psychological Science"
DOI: 10.1177/0956797618811877
Abstract: Social risk is a domain of risk in which the costs, benefits, and uncertainty of an action depend on the behavior of another individual. Humans overvalue the costs of a socially risky decision when compared… read more here.
