“…Surprisingly, no consistent correlation was found between either h′ and DCI nor between K and DCI in any age group. Although in several studies the DCI was used as an indicator of linearity within hierarchies (Koenig, 2000;French and Smith, 2005;Roden et al, 2005) and was quite high in the SOW groups it should rather be interpreted as an index of directionality in the dyadic interactions. Correlation between two-way dyads and the DCI but not between two-way dyads and h′ or K support this theory.…”

“…From 2 years of age, male bison already participate in contests over female access, although few are successful at this age (Roden et al 2003). Male weight is strongly related to rank in bison (Roden et al 2005) and can be considered a reasonable predictor of subsequent reproductive success (e.g. bighorn sheep: Festa-Bianchet et al 2000).…”

“…As research on social animals (hierarchical system) progresses, an increasing number of investigations indicate that many species produce and secrete a wide variety of chemical substances, frequently identified as scents. Although their precise function is still poorly understood, these substances have been frequently associated with different forms of olfactory communication in ungulates: mate recognition (Novotny et al 1990;Miller et al 1998;Rich & Hurst 1999), territory marking (Gosling 1982;Bowyer et al 1994) and sexual selection (Roden et al 2005;Hemelrijk et al 2008).…”

Abstract:The preorbital gland is a specialized dermal gland of antelopes which plays an important role in territorial marking behavior and pheromonal communication. To our knowledge, there is little information available on the role of preorbital gland marks in Indian antelopes (blackbucks). Males are seen averting the gland during behavioural display and territorial marking but the functional aspect of this gland has not been examined. Hence, the aim of this study was to describe the histomorphology of the preorbital gland in territorial and non-territorial male blackbucks to determine its morphology and secretory function. The results showed that the preorbital gland is composed of modified sebaceous and apocrine glands. The apocrine gland is lined by simple cuboidal epithelial cells; the serous parts of the secretory products are often seen in the apical portions of the cells. The myoepithelial cells contain actin filaments lying on the basal membranes of the apocrine gland. There are some considerable histological changes in the presence of the sebaceous and apocrine glands in territorial males in comparison to non-territorial males. The following histological changes associated with occurrence of the sebaceous and apocrine glands have been observed in territorial and non-territorial male blackbucks: (1) increase of size of sebaceous and apocrine glands and (2) increase in density of sebaceous and apocrine glands in territorial males compared to non-territorial males. It is suggested that the higher development (i.e., size) and density of sebaceous and apocrine glands in territorial males could depend on hormone production (i.e., testosterone). Based on the histological observation and the role of sebaceous and apocrine glands in the preorbital gland supported by literature, it is possible to conclude that both territorial and non-territorial blackbuck males may produce pheromonal substances through preorbital gland (secretion) for olfactory communication.
