Example Sentences:
(1) Long-term observations are presented on the behaviour of the siamang ape, Symphalangus syndactylus, in the lowland forest of central Malaya.

(5) Expression of human GPA antigenic determinants was consistent with the phylogeny of the hominoid primates; common and dwarf chimpanzee expressed most of the determinants tested, gorilla and orangutan an intermediate number, and gibbon and siamang the least.
(6) Genome size was measured as the amount of Feulgen-stained DNA in six species of the family Hylobatidae and in a hybrid of the gibbon (Hylobates muelleri) and siamang (Symphalangus syndactylus).
(7) A detailed study of a small sample of siamang and lar gibbons shows that they select figs in the morning, young leaves in the afternoon and figs again for the last feed of the day.
(8) Wild, adult siamang were observed for over 800 h in lowland dipterocarp forest in the Krau Game Reserve, Pahang, West Malaysia.
(9) In feeding, siamang use suspensory postures among small supports and seated postures on large supports.
(10) Banding patterns were observed in colobus' for D2S44, D1S7, and D4S139; owl monkeys for D2S44; gorillas for D2S44 and D4S139; gibbons for D2S44 and D4S139; siamangs for D2S44, talapoins for DiS7; cranes for D1S7; and otters for D1S7.
(11) Comparison of siamang locomotion and posture with that of other apes suggest that quadramanous climbing during feeding is the basic hominoid locomotor adaptation.
(12) Hybridization in situ was used to identify rDNA in chromosomes of the pygmy chimpanzee, mountain gorilla, and siamang gibbon.
(13) The ease of isolation and axenization of Giardia was surprising; five axenic isolates of Giardia, belonging to the G. duodenalis morphological group, were established from primates (slow loris, lesser slow loris and siamang) and from rodents (Gambian giant pouched rat and cuis).
(14) Laccopithecus robustus is a siamang-sized fossil ape from the Miocene site of Lufeng, China.

(18) Siamang use four patterns of locomotion: brachiation, climbing, bipedalism and leaping.
(19) The pattern of locomotion used by the siamang varies with the size of arboreal supports and with major behavioral activity.
(20) Mitochondrial DNA sequences encoding the cytochrome oxidase subunit II gene have been determined for five primate species, siamang (Hylobates syndactylus), lowland gorilla (Gorilla gorilla), pygmy chimpanzee (Pan paniscus), crab-eating macaque (Macaca fascicularis), and green monkey (Cercopithecus aethiops), and compared with published sequences of other primate and nonprimate species.
