  • primates
  • Predatory behavior in wild chimpanzees and other primates has been well documented over the last 30 years. (mdpi.com)
  • Predatory behavior in captive primates include reports of opportunistic individual predation of vertebrates by several species of the genus Galago , Saguinus , Saimiri , Cebus , Lagothrix , Macaca , Mandrillus and Cercopithecus [ 19 ]. (mdpi.com)
  • prey
  • Writing in the current issue of the journal Biotropica, O'Donnell and biologists Michael Kaspari of the University of Oklahoma and John Lattke of Universidad Central de Venezuela, propose that mass cooperative food foraging, a key element in the behavior of army ants, may have begun as a way to subdue large prey.

  • It had been previously identified, but little was known about its behavior or prey until the two chance encounters at the Tiputini Biodiversity Station, an ecological preserve in eastern Ecuador. (eurekalert.org)
  • emerge
  • 59, 63- a cooperative norm does not emerge in the treatments where players are matched randomly. (repec.org)
  • We demonstrate with computational simulation scenarios how social environments and individual behavior coevolve and how fundamentally different macro-effects emerge, when separate micromechanisms are combined. (uzh.ch)
  • factors
  • Additionally, we show that caching decisions were not solely due to motivational factors, instead showing an additional influence attributed to the behavior of the partner bird. (frontiersin.org)
  • individuals
  • Bshary and Oliveira, 2015 ) argues that social behaviors evolved to be flexible and that individuals can select from their full range of behavioral options to adjust to ever changing contexts. (frontiersin.org)
  • Continuing their general catalog of correlations of left versus right frontal lobe activation with outgoing versus protective behaviors they find that individuals with greater tonic (resting) activity in right-posterior dorsolateral prefrontal cortex rate themselves as more behaviorally inhibited. (dericbownds.net)
  • increases
  • Cooperative behavior spreads three degrees of separation: if Eleni increases her contribution to the public good, it benefits Lucas (one degree), who gives more when paired with Erika (two degrees) in period 2, who gives more when paired with Jay (three degrees) in period 3, who gives more when paired with Brecken in period 4. (dericbownds.net)
  • individual
  • Enabling promotes a permissive behavior, and so it never helps the individual with a substance abuse problem or compulsive disorder. (mental-health-matters.com)
  • The only way that an individual with substance abuse can be freed from such behavior is to address the immediate cause. (mental-health-matters.com)
  • However, the conditions in which an individual chooses to act in a cooperative fashion are still unclear ( Bshary and Oliveira, 2015 ). (frontiersin.org)
  • Thus, it would be advantageous for an individual to be capable of judging whether the cooperative act will come at a cost or benefit, and adjust the degree to which one cooperates accordingly ( Trivers, 1971 ). (frontiersin.org)
  • study
  • The purpose of the present study was to examine the relationship between children's oppositional behavior and the following two variables: number of commands issued and time from command presentation. (biomedsearch.com)
  • wild
  • This demonstrated that they were able to perform this species-typical behavior in a naturalistic environment without learning it in the wild. (mdpi.com)
  • treatment
  • The treatment successfully elevated circulating glucocorticoid levels but did not result in significant changes in pup feeding or sentinel behavior. (ovid.com)
  • maintain
  • This term refers to a person whose words or actions are helping someone to maintain or continue with their bad behavior (in this case, addiction). (mental-health-matters.com)
  • In this scenario, if caching behaviors can be flexibly deployed, then the birds should recognize the cooperative nature of the task and maintain or increase caching levels over time. (frontiersin.org)
