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.

Anatomical and molecular analyses of the deltoid muscle in chimpanzees (Pan troglodytes) and modern humans (Homo sapiens): Similarities and differences due to the uses of the upper extremity

DOI: 10.1002/ajp.23390
Abstract: In the deltoid muscles of Pan troglodytes and Homo sapiens, we have analyzed the muscle architecture and the expression of the myosin heavy chain (MHC) isoforms. Our aim was to identify differences between the two… 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.

DOI: 10.1002/ece3.7633
Abstract: Abstract The common chimpanzee Pan troglodytes is the closest extant relative of modern humans and is often used as a model organism to help understand prehistoric human behavior and ecology. Originally presumed herbivorous, chimpanzees have… 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: 10.1098/rstb.2021.0299
Abstract: Gestures play an essential role in primate communication. However, little is known about how complexity of gestural use (in terms of repertoire size, intentional use, flexibility and use of gestural sequences) relates to individual and… read more here.

DOI: 10.1111/jmp.12637
Abstract: Urinalysis is a rapid, non‐invasive method used to obtain diagnostic information on primates. While several studies have investigated dipstick and specific gravity values in chimpanzees, urine sediment analysis is often excluded. Crystalluria, observed during urine… read more here.
