  • Elsewhere in the chacma baboon distribution (in nonconflict areas), artificial food patches have been shown to alter troop movements drastically by eliciting consistent leadership behavior from alpha males. (springer.com)
  • adult
  • Evidence has also been provided for the effect of sociality on adult survival in wild baboons. (wikipedia.org)
  • In the yellow baboon, adult females form relationships with their kin, who offer support during times of violent conflict within social groups. (wikipedia.org)
  • For example, adult male baboons readily interact with food-based devices, which can result in the reduction of stereotypical behaviors, and in the elicitation of species-typical behaviors such as foraging and grooming (Pyle et al. (brown.edu)

  • behavior
  • In particular, grooming in yellow baboons (Papio cynocephalus) has been studied extensively, with numerous studies showing an increase in fitness as a result of social bonds formed through social grooming behavior. (wikipedia.org)
  • occurrence
  • Baboons with lower tick loads show decreased occurrence of such infections and display signs of greater health status, evidenced by higher hematocrit (packed red cell volume) levels. (wikipedia.org)
  • Some ethograms are given in pictorial form and not only catalogue the behaviours but indicate the frequency of their occurrence and the probability that one behaviour follows another. (wikipedia.org)

KEY WORDS Kenya baboons, Immunoglobulins,Local variations ABSTRACT In this paper we report on the distributions of immunoglobulin allotypes among 564 olive baboons collected at six localities in Kenya. (docme.ru)
  • males
  • We found that several acoustic features varied consistently across age and status such that males deemed higher quality in gelada society ( e.g. , high status) produced more calls per bout, produced calls that were lower in overall frequency measures, and exhibited a greater vocal range. (springer.com)
  • among
  • We are investigating the genetic basis of variation in temperament among baboons ( Papio hamadryas ). (asp.org)
  • 1996). On the other hand, use of non-food-related devices (e.g., logs, Kong toys, and swings) can vary considerably among individuals, with some baboons showing decreased, others increased, use over time (Hienz, et al. (brown.edu)
  • Diseases such as measles and tuberculosis are highly prevalent among the local human population ( 7 ) and have the potential to pass to baboons. (cdc.gov)
  • samples
  • The proportions of individuals positive for polymorphic allotypes varied substantially between different local samples, as did the arrays and estimated frequencies of haplotypes. (docme.ru)
  • Allotype frequencies in local samples do not appear to be simply related to either geographic location or habitat characteristics of the localities. (docme.ru)
  • Samples of feces from each baboon were collected from the cage floor. (cdc.gov)
  • male
  • Direct correlations between measures of social connectedness (which focuses on social grooming) and median survival time for both female and male baboons were modeled. (wikipedia.org)
  • Twenty-seven baboons (15 male, 12 female) from 5 troops were screened for 10 zoonotic infections in April 2011. (cdc.gov)

  • absence
  • However, this method is costly and suffers from short-term interruptions, wherein the unexpected absence of monitors may lead to unprepared residents using lethal force to deter raiding baboons. (springer.com)
  • We investigated whether an artificial patch could be used to draw baboons away from the urban environment in the absence of monitors. (springer.com)
  • form
  • Accentu- ated lines visible in histological sections of teeth are indicators of stress during enamel formation and have been hypothesised to form in baboon teeth during weaning. (ncl.ac.uk)

  • After 30 minutes, the mirror was re-introduced into the room and the frequency of touching the marked areas again determined. (wikipedia.org)
  • shown
  • Grooming has also been shown to play an integral role in reducing tick load in wild baboons (Papio cynocephalus). (wikipedia.org)
  • In wild savannah baboons, social affiliations are shown to augment fitness by increasing tolerance from more dominant group members and increasing the chance of obtaining aid from conspecifics during instances of within-group contest interactions. (wikipedia.org)
  • Previous studies in our laboratory have documented the use of enrichment devices by singly caged baboons, and have shown various differences in the use of food-based and non-food-based devices. (brown.edu)
  • years
  • One such study, which collected 16 years of behavioral data on wild baboons, highlights the effects that sociality has on infant survival. (wikipedia.org)
  • vary
  • 2000). Enrichment device use can also vary as a function of the frequency of availability of the device: log use, for example, is enhanced when the log is available every other day or every fourth day, while activity declines if the log is withheld longer than every fourth day or if it is continuously available. (brown.edu)
  • Results
  • Results include significant LOD scores on baboon chromosomes 8 (F2) and 10 (HVA and 5-HIAA), and other suggestive evidence of linkages (F1 and F2). (asp.org)
  • high
  • The criterion is that the frequency of the least common morph is too high simply to be the result of new mutations or, as a rough guide, that it is greater than 1% (though that is far higher than any normal mutation rate for a single allele). (wikipedia.org)
  • A high frequency of fires removes this stratum and young saplings and leads to Miombo Woodland with large, widely separated trees. (wikipedia.org)
  • mirror
  • We scored 578 baboons for reactivity to three novel objects (toys and mirror), by recording the frequencies and durations of 73 behaviors. (asp.org)
  • The frequency of touching increased to 4-10 with the mirror present, compared to only 1 when the mirror had been removed. (wikipedia.org)
