A geometric morphometric analysis of acetabular shape of the primate hip joint in relation to locomotor behaviour

“…Gibbons are brachiators par excellence (Fleagle, 2013), but they also employ a wide variety of other locomotor modes, such as diving, clambering, bipedal walking, bridging, jumping (including ricocheting), running, leaping, quadrumanous climbing, and scrambling (Carpenter, 1964;Fleagle, 1976;Cannon and Leighton, 1994;Sati and Alfred, 2002;Vereecke et al, 2005Vereecke et al, , 2006Amarasinghe and Amarasinghe, 2010;Cheyne et al, 2013). As such, they use bipedal, tripedal, or quadrupedal gaits (Carpenter, 1964;Fleagle, 1976;Nakano, 2002).…”

Ticks, Hair Loss, and Non-Clinging Babies: A Novel Tick-Based Hypothesis for the Evolutionary Divergence of Humans and Chimpanzees

“…Arboreal primates are highly susceptible to forest fragmentation due to the patchy distribution of fruit-bearing trees and their need to access large forest areas [ 54 ]. For example, although gibbons are arboreal and normally remain within the canopy [ 40 ], they may descend to the forest floor when crossing gaps in fragmented habitats [ 78 , 79 , 80 , 81 ]. On the ground, primates are exposed to predators and diseases that they would not normally encounter in an arboreal environment [ 49 , 79 , 82 , 83 ].…”

Best Practice Guidelines for the Rehabilitation and Translocation of Gibbons

“…• Habitat structure: gibbons preferentially use upper and lower canopy trees for daily travel, feeding, social activities and resting and avoid areas with large and frequent gaps in the canopy (Cannon & Leighton, 1996;Kadhafi, 2011;Cheyne, et al, 2013a). Emergents are essential for singing sites and sleeping sites (depending on species; Whitten, 1982;Reichard 1998;Chetry, et al, 2008;Poonjampa, et al, 2010;Cheyne, 2010;Cheyne, et al 2013b).…”
