Pan paniscus and Pan troglodytes

1984
Previous ape language studies have been undertaken with common chimpanzees (Pan troglodytes), orangutans (Pongo pygmaeus), and gorillas (Gorilla gorilla) (Gardner and Gardner, 1969; Rumbaugh, 1977, Savage-Rumbaugh, 1979; Miles, 1982; Patterson and Linden, 1981).

The complete mitochondrial genome of the central chimpanzee, Pan troglodytes troglodytes

Mitochondrial DNA Part A, 2015
This study first report the complete mitochondrial genome sequence of the central chimpanzee, Pan troglodytes troglodytes. The genome was a total of 16 556 bp in length and had a base composition of A (31.05%), G (12.95%), C (30.84%), and T (25.16%), indicating that the percentage of A + T (56.21%) is higher than G + C (43.79%).

Central Chimpanzees, Pan troglodytes troglodytes

2023
Abstract This chapter describes the Ubangi River in the northwestern Democratic Republic of Congo, which is an impassible divide of the schweinfurthii to its east and the troglodytes to its west. It talks about the known populations of chimpanzees that are dwindling through disease, hunting, and deforestation, although its total numbers ...

Sweating responses in the chimpanzee (Pan troglodytes)

Comparative Biochemistry and Physiology Part A: Physiology, 1976
Abstract o 1. In contrast to man, in chimpanzees, rapid, heavy sweating is concentrated around the axillae rather than the chest and back. 2. Chimpanzees were unable to maintain a constant body temperature at ambient temperatures (Ta) above 37°C. 3. Evaporative water loss at Ta around 37°C were more than double that at 18·7°C. 4.

Summation in the chimpanzee (Pan troglodytes).

Journal of Experimental Psychology: Animal Behavior Processes, 1987
In this research, we asked whether 2 chimpanzee (Pan troglodytes) subjects could reliably sum across pairs of quantities to select the greater total. Subjects were allowed to choose between two trays of chocolates. Each tray contained two food wells. To select the tray containing the greater number of chocolates, it was necessary to sum the contents of

Etiology of reactive arthritis in Pan paniscus, P. troglodytes troglodytes, and P. troglodytes schweinfurthii

American Journal of Primatology, 2005
AbstractThe character of arthritis has not received the same attention in Pan paniscus as it has in P. troglodytes. Reactive arthritis (a form of spondyloarthropathy) in the latter has been considered to be either a sexually transmitted or an infectious‐agent diarrhea‐related disorder. The unique sexual promiscuity of P.

Molar development in common chimpanzees (Pan troglodytes)

Journal of Human Evolution, 2007
Numerous studies have reported on enamel and dentine development in hominoid molars, although little is known about intraspecific incremental feature variation. Furthermore, a recent histological study suggested that there is little or no time between age at chimpanzee crown completion and age at molar eruption, which is unlikely given that root growth

Imitation in neonatal chimpanzees (Pan troglodytes)

Developmental Science, 2004
AbstractThis paper provides evidence for imitative abilities in neonatal chimpanzees (Pan troglodytes), our closest relatives. Two chimpanzees were reared from birth by their biological mothers. At less than 7 days of age the chimpanzees could discriminate between, and imitate, human facial gestures (tongue protrusion and mouth opening).

Finger drawing by infant chimpanzees ( Pan troglodytes )

Animal Cognition, 2003
We introduced a new technique to investigate the development of scribbling in very young infants. We tested three infant chimpanzees to compare the developmental processes of scribbling between humans and chimpanzees. While human infants start to scribble on paper at around the age of 18 months, our 13- to 23-month-old infant chimpanzees had never been

Conjugate lateral eye movements in Pan troglodytes

Neuropsychologia, 1978
Abstract The direction of conjugate lateral eye movements was assessed in four juvenile and four adolescent chimpanzees ( Pan troglodytes ). A significant bias in favor of left eye movements was found in the two older adolescents. Neither the two younger adolescents nor the four juveniles revealed a significant asymmetry in the direction of conjugate
