Title Use of leaves to inspect ectoparasites in wild chimpanzees: a third cultural variant? Type Journal Article
Year 2004 Publication Primates Abbreviated Journal Primates
Volume 45 Issue 4 Pages 255-258
Keywords Animals; Animals, Wild/physiology; Ape Diseases/*parasitology; Behavior, Animal/*physiology; Ectoparasitic Infestations/parasitology/*veterinary; Female; Grooming/*physiology; Male; Pan troglodytes/*physiology; *Plant Leaves; Protozoa/*isolation & purification; Uganda
Abstract We report 26 cases of using leaves as tools with which wild chimpanzees (Pan troglodytes schweinfurthii) in the Sonso community, Budongo Forest, Uganda, appeared to inspect objects removed during grooming. Careful removal of potential ectoparasites and delicate lip or manual placement on leaves followed by intense visual examination characterised this behaviour. It appears to be done to judge whether either ingestion or discarding is most appropriate, the former occurring in most cases. This behaviour may represent a third variant of ectoparasite handling, different from those described at Tai and Gombe, yet sharing features with the latter. These two East African techniques may thus have evolved from leaf grooming.

Title Imitative learning by captive western lowland gorillas (Gorilla gorilla gorilla) in a simulated food-processing task Type Journal Article
Year 2001 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 115 Issue 3 Pages 272-281
Keywords Animals; Behavior, Animal/physiology; *Discrimination Learning; Feeding Behavior/*physiology; Gorilla gorilla; *Imitative Behavior; Social Behavior
Abstract Although field studies have suggested the existence of cultural transmission of foraging techniques in primates, identification of transmission mechanisms has remained elusive. To test experimentally for evidence of imitation in the current study, we exposed gorillas (Gorilla gorilla gorilla) to an artificial fruit foraging task designed by A. Whiten and D. M. Custance (1996). Gorillas (n=6) watched a human model remove a series of 3 defenses around a fruit. Each of the defenses was removed using 1 of 2 alternative techniques. Subsequent video analysis of gorillas' behavior showed a significant tendency to copy the observed technique on 1 of the individual defenses and the direction of removal on another defense. This is the first statistically reliable evidence of imitation in gorillas. Sequence of defense removal was not replicated. The gorillas' responses were most similar to those of chimpanzees.

Title Cultures in chimpanzees Type Journal Article
Year 1999 Publication Nature Abbreviated Journal Nature
Volume 399 Issue 6737 Pages 682-685
Keywords Animals; *Behavior, Animal; Cognition; *Culture; Humans; Pan troglodytes/*physiology; Species Specificity
Abstract As an increasing number of field studies of chimpanzees (Pan troglodytes) have achieved long-term status across Africa, differences in the behavioural repertoires described have become apparent that suggest there is significant cultural variation. Here we present a systematic synthesis of this information from the seven most long-term studies, which together have accumulated 151 years of chimpanzee observation. This comprehensive analysis reveals patterns of variation that are far more extensive than have previously been documented for any animal species except humans. We find that 39 different behaviour patterns, including tool usage, grooming and courtship behaviours, are customary or habitual in some communities but are absent in others where ecological explanations have been discounted. Among mammalian and avian species, cultural variation has previously been identified only for single behaviour patterns, such as the local dialects of song-birds. The extensive, multiple variations now documented for chimpanzees are thus without parallel. Moreover, the combined repertoire of these behaviour patterns in each chimpanzee community is itself highly distinctive, a phenomenon characteristic of human cultures but previously unrecognised in non-human species.

Title Imitation of the sequential structure of actions by chimpanzees (Pan troglodytes) Type Journal Article
Year 1998 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 112 Issue 3 Pages 270-281
Keywords Animals; Appetitive Behavior/physiology; *Ceremonial Behavior; Exploratory Behavior/physiology; Female; Fruit; Imitative Behavior/*physiology; Learning/*physiology; Male; Pan troglodytes/*psychology; Practice (Psychology); Problem Solving/*physiology
Abstract Imitation was studied experimentally by allowing chimpanzees (Pan troglodytes) to observe alternative patterns of actions for opening a specially designed “artificial fruit.” Like problematic foods primates deal with naturally, with the test fruit several defenses had to be removed to gain access to an edible core, but the sequential order and method of defense removal could be systematically varied. Each subject repeatedly observed 1 of 2 alternative techniques for removing each defense and 1 of 2 alternative sequential patterns of defense removal. Imitation of sequential organization emerged after repeated cycles of demonstration and attempts at opening the fruit. Imitation in chimpanzees may thus have some power to produce cultural convergence, counter to the supposition that individual learning processes corrupt copied actions. Imitation of sequential organization was accompanied by imitation of some aspects of the techniques that made up the sequence.

Title The use of altrenogest to control aggression in a male Grant's Zebra (Equus burchelli boehmi) Type Journal Article
Year 2006 Publication Journal of zoo and wildlife medicine : official publication of the American Association of Zoo Veterinarians Abbreviated Journal J Zoo Wildl Med
Volume 37 Issue 1 Pages 61-63
Keywords Aggression/*drug effects; Animals; Animals, Zoo; Behavior, Animal/*drug effects; Dose-Response Relationship, Drug; Equidae/*physiology; Female; Horses; Male; Treatment Outcome; Trenbolone/*analogs & derivatives/therapeutic use
Abstract A male Grant's Zebra (Equus burchelli boehmi) housed with two mares at the Indianapolis Zoo had a 9-yr history of intermittent aggressive behavior toward mares and other animals. Periods of separation allowed the mares time to heal after sustaining superficial bite wounds. On 26 March 2003, the male (890293) was started on altrenogest at a dosage of 19.8 mg orally once daily to allow reintroduction. The dosage was doubled (40 mg once a day) because of a perceived lack of response. Reintroduction to the mares occurred on 17 May 2003 with no signs of aggression noted. Treatment was reduced to 19.8 mg orally once a day and then discontinued. Altrenogest was restarted at 39.5 mg orally once a day because of the planned introduction of a new mare. There have been no major aggressive displays at this dosage of altrenogest and the dosage has recently been reduced following successful introduction of a new mare.

Title Cone excitation ratios correlate with color discrimination performance in the horse (Equus caballus) Type Journal Article
Year 2006 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 120 Issue 4 Pages 438-448
Keywords Animals; Behavior, Animal; *Color Perception; *Discrimination (Psychology); Discrimination Learning; Horses; Photoreceptors, Vertebrate/*physiology
Abstract Six horses (Equus caballus) were trained to discriminate color from grays in a counterbalanced sequence in which lightness cues were irrelevant. Subsequently, the pretrained colors were presented in a different sequence. Two sets of novel colors paired with novel grays were also tested. Performance was just as good in these transfer tests. Once the horse had learned to select the chromatic from the achromatic stimulus, regardless of the specific color, they were immediately able to apply this rule to novel stimuli. In terms of the underlying visual mechanisms, the present study showed for the first time that the spectral sensitivity of horse cone photopigments, measured as cone excitation ratios, was correlated with color discrimination performance, measured as accuracy, repeated errors, and latency of approach.
