Abstract
In addition to the nine compounds identified in the interdigital secretion of the bontebok, Damaliscus dorcas dorcas, in a previous study, 76 compound s belonging to different compound types, were identified in the interdigita l secretions of the bontebok and the blesbok, D, d. phillipsi. These compou nds include alkanes, alcohols, aldehydes, ketones, fatty acids, terpenoids, gamma-lactones, an isopropyl ester, long-chain hydroxyesters, 2-substitute d pyridines, phenols, steroids, and dimethylsulfone. No qualitative differe nces were found between secretions from the two sexes or from animals from different habitats. Although no attempt was made to correlate territorial b ehavior or other behavioral phenomena with the qualitative composition of i nterdigital secretions from individual animals, available information seems to indicate that quantitative differences probably do not have a major sem iochemical function. Only two species of bacteria, Bacillus brevis and Plan ococcus citreus, were found in the interdigital pouches of male and female members of the two subspecies, regardless of the habitat of the animals. B. brevis synthesized, among other unidentified constituents, (Z)-3-penten-2- ol, 2-hexanone. 2-octanone, 2-nonanone, tetradecanoic acid, pentadecanoic a cid, heptadecanoic acid, octadecanoic acid, (Z)-9-hexadecenoic acid, and is opropyl hexadecanoate in vitro, while P. citreus produced, among others, th e gamma-lactones dodecan-4-olide and (Z)-6-dodecen-4-olide, which is one of the major constituents of the interdigital secretions of both subspecies. Some components of the interdigital secretions are not present in the inter digital,glandular tissue, and the possibility is discused that these compou nds could be produced by microbiological activity in the interdigital pouch .
