With one exception, the eastern hoolock, all ape species and their subspecies are classi- fied as endangered or critically endangered by the International Union for Conservation of Nature (IUCN) (IUCN, 2016c). Since apes require access to forested or wooded land- scapes, habitat loss represents a major cause of population decline, as does hunting in these settings (Geissmann, 2007; Hickey et al., 2013; Plumptre et al., 2016b; Stokes et al., 2010; Wich et al., 2008).

AN ABSTRACT OF THE THESIS OF Erin Lee Osterud for the Master of Arts in Anthropology presented July 18, 1988. Title: Gibbon Classification: The Issue of Species and Subspecies. APPROVED BY MEM~ OF THE THESIS COMMITTEE: Marc R. Feldesman, Chairman Gibbon classification at the species and subspecies levels has been hotly debated for the last 200 years. This thesis explores the reasons for this debate. Authorities agree that siamang, concolor, kloss and hoolock are species, while there is complete lack of agreement on lar, agile, moloch, Mueller's and pileated. The disagreement results from the use and emphasis of different character traits, and from debate on the occurrence and importance of gene flow.

7 Gibbon Song and Human Music from An
Gibbon Song and Human Music from an 7 Evolutionary Perspective Thomas Geissmann Abstract Gibbons (Hylobates spp.) produce loud and long song bouts that are mostly exhibited by mated pairs. Typically, mates combine their partly sex-specific repertoire in relatively rigid, precisely timed, and complex vocal interactions to produce well-patterned duets. A cross-species comparison reveals that singing behavior evolved several times independently in the order of primates. Most likely, loud calls were the substrate from which singing evolved in each line. Structural and behavioral similarities suggest that, of all vocalizations produced by nonhuman primates, loud calls of Old World monkeys and apes are the most likely candidates for models of a precursor of human singing and, thus, human music. Sad the calls of the gibbons at the three gorges of Pa-tung; After three calls in the night, tears wet the [traveler's] dress. (Chinese song, 4th century, cited in Van Gulik 1967, p. 46). Of the gibbons or lesser apes, Owen (1868) wrote: “... they alone, of brute Mammals, may be said to sing.” Although a few other mammals are known to produce songlike vocalizations, gibbons are among the few mammals whose vocalizations elicit an emotional response from human listeners, as documented in the epigraph. The interesting questions, when comparing gibbon and human singing, are: do similarities between gibbon and human singing help us to reconstruct the evolution of human music (especially singing)? and are these similarities pure coincidence, analogous features developed through convergent evolution under similar selective pressures, or the result of evolution from common ancestral characteristics? To my knowledge, these questions have never been seriously assessed. -

CROGNALE,§ MAUREEN NEITZT Received 6 November 1992; in revised form 3 February 1993 The owl monkey (Aotus tridrgutus) is the only nocturnal monkey. The photopigments of Aotus and the relationship between these photopigments and visual discrimination were examined through (1) an analysis of the tlicker photometric electroretinogram (ERG), (2) psychophysical tests of visual sensitivity and color vision, and (3) a search for the presence of the photopigment gene necessary for the production of a short-wavelength sensitive (SWS) photopigment. Roth electrophysiological and behavioral measurements indicate that in addition to a rod photopigment the retina of this primate contains only one other photopigment type-a cone pigment having a spectral peak cu 543 nm. Earlier results that suggested these monkeys can make crude color discriminations are interpreted as probably resulting from the joint exploitation of signals from rods and cones. Although Aotus has no functional SWS photopigment, hybridization analysis shows that A&us has a pigment gene that is highly homologous to the human SWS photopigment gene.

This finding has considerable implications for our perception of torpor in this mammal group and demonstrates that torpor is probably more widespread in mammals than commonly thought. This article summarizes the current knowledge on the use of torpor in the pygmy loris and places it into the context of ongoing research on this topic.

Vietnamese Journal of Primatology (2009) 3, 37-44 Diet and feeding behaviour of pygmy lorises (Nycticebus pygmaeus) in Vietnam Ulrike Streicher Wildlife Veterinarinan, Danang, Vietnam. <[email protected]> Key words: Diet, feeding behaviour, pygmy loris Summary Little is known about the diet and feeding behaviour of the pygmy loris. Within the Lorisidae there are faunivorous and frugivorous species represented and this study aimed to characterize where the pygmy loris (Nycticebus pygmaeus) ranges on this scale. Feeding behaviour was observed in adult animals which had been confiscated from the illegal wildlife trade and housed at the Endangered Primate Rescue Center at Cuc Phuong National Park for some time before they were radio collared and released into Cuc Phuong National Park. The lorises were located in daytime by methods of radio tracking and in the evenings they were directly observed with the help of red-light torches. The observed lorises exploited a large variety of different food sources, consuming insects as well as gum and other plant exudates, thus appearing to be truly omnivorous. Seasonal variations in food preferences were observed. Omnivory can be an adaptive strategy, helping to overcome difficulties in times of food shortage. The pygmy loris’ feeding behaviour enables it to rely on other food sources like gum in times when other feeding resource become rare. Gum as an alternative food sources has the advantage of being readily available all year round. However it does not permit the same energetic benefits and consequently the same lifestyle as other food sources. But it is an important part of the pygmy loris’ multifaceted strategy to survive times of hostile environmental conditions. -
