Energetic cost of nut-cracking behaviour in wild chimpanzeesThe resulting assumption is that such additional food sources supply this species with a net benefit. Many reports from various sites describe a variety of tool-using behaviour in wild chimpanzees. The cracking of nuts is one of them. Here, a first attempt is made to measure the energy budget of nutnovelty 发表于 2025-3-26 10:16:19

New results concerning the vascularization of primate handsrevealed the most complex pattern in Old World monkeys: In Cercopithecidae, three palmar arches are formed by the perforating branches of the second dorsal metacarpal artery: two proximal (catella volaris proximalis and arcus volaris profundus) and one distal (catella volaris distalis).
