During this investigation data were collected on immature male (from birth to 5 years of age) social relations with adult males. Social relations between these two classes of males varied both in type and in frequency of behaviors displayed. During the first study, when the troop was predominantly multi-male, young males directed various tense behaviors toward adult males. Monthly rates of occurrence of such behaviors fluctuated and showed a positive correlation with rates of agonistic behaviors between adult males. In contrast, interactions between the adult and immature males were considerably more relaxed during the second and third studies when the troop had but 1 adult male. Based on the results of these studies, and data evaluated from other studies of P. entellus, it is hypothesized that the frequency and patterning of interactions between adult males affect adult male relations with young males.</p>","PeriodicalId":520627,"journal":{"name":"Folia primatologica; international journal of primatology","volume":" ","pages":"19-38"},"PeriodicalIF":1.9,"publicationDate":"1982-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000156042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35358623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During summer, broadleaf forest provides the basic foraging substrate for the langurs, and when its resources fail during the winter dry season, they radically shift their diet and feed largely in meadow, range over wider areas, use their range more evenly and make longer day journeys.

However, color vision tests (neutral point, anomaloscope, and wavelength discrimination) indicated that at least two qualitatively different types of color vision exist among spider monkeys. The female tested had essentially normal trichromatic color vision (although her anomaloscope match was shifted slightly in the deutan direction) with acute wavelength discrimination. The male, however, was clearly a protanomalous trichromat. He required much more red light in a red/green mixture to match a standard yellow than did normal trichromats.
