• Approaches to studying behavior in captive sloth bears through animal keeper feedback

      Khadpekar, Yaduraj; Whiteman, John P.; Durrant, Barbara S.; Owen, Megan A.; Prakash, Sant (2018)
      Animal keepers at zoos and wildlife rescue centers often possess in-depth knowledge of the health and behavior of the individuals under their care. While it is often not feasible for keepers to regularly collect behavior data through formal scientific methods, efforts should be made to find alternative means to capture this knowledge.....
    • Behavior coding and ethogram of Guizhou snub-nosed monkey (Rhinopithecus brelichi)

      Cui, Duoying; Niu, K.; Tan, Chia L.; Yang, M.; Zhang, Y.; Zhang, J.; Yang, Y. (2014)
      We observed the behavior processes and habitats of free-ranging Guizhou snub-nosed monkeys (Rhinopithecus brelichi) in Fanjingshan National Nature Reserve (FNNR) and captive Guizhousnub-nosed monkeys in Wildlife Rescue Center in FNNR and Beijing Zoo from October 2009 to April 2014…. We found that there were some behavioral differences among Guizhou snub-nosed monkey, Sichuan snub-nosed monkey and Yunnan snub-nosed monkey in individual and social behaviors, and these might be related to the different habitats.
    • Body size, not phylogenetic relationship or residency, drives interspecific dominance in a little pocket mouse community

      Chock, Rachel Y.; Shier, Debra M.; Grether, Gregory F. (2018)
      The role of interspecific aggression in structuring ecological communities can be important to consider when reintroducing endangered species to areas of their historic range that are occupied by competitors. We sought to determine which species is the most serious interference competitor of the endangered Pacific pocket mouse, Perognathus longimembris pacificus, and more generally, whether interspecific aggression in rodents is predicted by body size, residency status or phylogenetic relatedness....
    • Social influences on the estrous cycle of the captive sun bear (Helarctos Malayanus): Sun bear social influences

      Frederick, Cheryl; Hunt, Kathleen; Kyes, Randall; Collins, Darin; Durrant, Barbara S.; Ha, James; Wasser, Samuel K. (2013)
      We examined the potential influences of existing social housing arrangements on captive sun bear female reproductive cycling. Three social conditions were studied: 1.2, 1.1, and 0.2. Fecal hormone metabolites of total estrogens, progestins and glucocorticoids were compared between the three social conditions and were analyzed along with vaginal cytology data in individuals that experienced a change in social condition....
