1997. A curated database of candidate human ageing-related genes and genes associated with longevity and/or ageing in model organisms. Their status is in part due to the flourishing illegal pet trade in Thailand, in which they are hunted, captured, traded, and exploited. Grooming site preferences in wild white-handed gibbons (Hylobates lar). Lar gibbons do not have tails. The same food sources are returned to multiple times during peak season to eat the ripest fruit each time (Whitington and Treesucon, 1991). "Conservation difficulties for Hylobates lar: effects the illegal pet trade has on white-handed gibbons' behavioral health and successful rehabilitation" Young gibbons will stay with their parents in a family unit until they are old enough to venture off on their own and start their own family. White-handed gibbons have the largest latitudinal range of Hylobates species (Gron, 2010). Brockelman, W. 2004. 1985. gonochoric/gonochoristic/dioecious (sexes separate), Eat or be eaten: predator sensitive foraging among primates, National History Bulletin of the Siam Society, http://www.iucnredlist.org/details/10548/0, https://www.lafayette.in.gov/egov/docs/298271201804574.htm, http://www.academia.edu/1525036/Conservation_Difficulties_for_Hylobates_lar_Effects_the_Illegal_Pet_Trade_has_on_White-handed_Gibbons_Behavioral_Health_and_Successful_Rehabilitation, http://pin.primate.wisc.edu/factsheets/entry/lar_gibbon, © 2020 Regents of the University of Michigan. Group encounters in wild gibbons (Hylobates lar): agonism, affiliation, and the concept of infanticide. (Savini, et al., 2009), Lar gibbons live, on average, 30 years in the wild and up to 44 years in captivity (Columbian Park Zoo, 2012). A species is polymorphic if its individuals can be divided into two or more easily recognized groups, based on structure, color, or other similar characteristics. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Analyses using the AnAge database to study the evolution of longevity and ageing in vertebrate lineages. This material is based upon work supported by the Weaning lasts about 20 months. HAGR may be freely used for all purposes under some conditions. Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. cm. Normal duets are a function of territoriality; signaling to neighboring groups who pose a threat (Raemaekers and Raemaekers, 1985). associates with others of its species; forms social groups. Studies focused on cancer, in particular using genomics and bioinformatics approaches. "many forms." Disclaimer: Synapomorphy of the Bilateria. The Journal of Infectious Diseases, 120: 292-297. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. Allo-grooming probably serves more as a hygienic activity than a social function for this species (Reichard and Sommer, 1994). Sleeping sites, sleeping places, and presleep behavior of gibbons (Hylobates lar). Lar gibbons are usually active for an average of 8.7 hours per day, leaving their sleeping sites right around sunrise and entering sleeping trees an average of 3.4 hours before sunset. Software for ageing research, including the Ageing Research Computational Tools (ARCT) perl toolkit. Polymorphic characteristics may be inherited because the differences have a genetic basis, or they may be the result of environmental influences. Family: Hylobatidae. A curated database of ageing and life history information in animals, including extensive longevity records. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. (Raemaekers and Raemaekers, 1985; Savini, et al., 2009), White-handed gibbons are largely frugivorous animals, eating ripe fruit from woody climbers and tropical trees (Whitington and Treesucon, 1991) (Savini et al., 2009). for Old World monkeys. Smith, P., T. Yuill, R. Buchanan, J. Stanton, V. Chaicumpa. An educational and information resource on the science of ageing. change in fur color), or age-related changes to be polymorphic. 2009. Beaman, M. 2014. Our lab leads the upkeep and development of HAGR. Contributor Galleries having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Accessed the area in which the animal is naturally found, the region in which it is endemic. Reichard, U. Referring to a mating system in which a female mates with several males during one breeding season (compare polygynous). (Brockelman and Geissmann, 2008). Duets occur between sunrise and noon, and peak at mid-morning. These calls average 11 minutes and can be heard up to one kilometer away (Raemaekers and Raemaekers, 1985). Hylobates lar Common name White-handed gibbon Lifespan, ageing, and relevant traits Maximum longevity 56 years (captivity) Source John Gramieri, pers. Varying ecological quality influences the probability of polyandry in white-handed gibbons (Hylobates lar) in Thailand. (Columbian Park Zoo, 2012), Gibbons use vocalization for intraspecific communication. The bibliographic library for ageing research. Fruits are tasted and either accepted or rejected based on ripeness. having the capacity to move from one place to another. Lar gibbons live, on average, 30 years in the wild and up to 44 years in captivity (Columbian Park Zoo, 2012). International Journal of Primatology, 29: 823-844. Males sing together at range edges to chase away intruders and group defense becomes more important as home range size increases (Savini et al., 2009).
