“…Therefore, males had possibility to form larger groups in August to November, taking advantage of the high availability of forage, and to form smaller groups in January to June. Similar to other studies on other ungulate species (Habibi 1997, Shi et al 2005, mixed-sex groups of Siberian ibex were largest than the other group typologies, and are mainly formed in the pre-rut (October) or earlyrutting period (November). This group type is formed throughout the year, or at least until April because of the limited areas with available forage inducing ibex to gather into larger mixed-sex groups (Johnsingh et al 1999).…”

“…Our results thus indicate an association between feeding type and group size. Similarly, this phenomenon was also recorded in Japanese serow (Capricornis crispus -Takada & Minami 2018), Nubian ibex (Capra nubiana -Habibi 1997) and feral goats (Capra hircus - Shi et al 2005), as they preferred to disperse in rugged terrain, where food patches were distributed unevenly. Besides the influencing of feeding ecology, predation risk could also partly explain the grouping pattern of Siberian ibex.…”

“…Social organization of various species is adapted to the abundance and distribution of resources (habitat structure and the spatial-temporal distribution of food) and to predation risk (Geist 1974, Jarman 1974, Gerard et al 2002. Habibi (1997) found that similar to other Caprini, the Nubian ibex (Capra nubiana) usually forms small groups of two to seven individuals. Sparse vegetation cover and scattered plant patches are characteristics that favours small group size.…”

“…Female associations form the basis of the social system in many ungulates (Geist 1971;Schaller 1977;Greenwood 1980;Habibi 1997), and this appears to be the case for blue sheep (Pseudois nayaur Hodgson, 1833). Blue sheep are highly social ungulates living in herds (Wang et al 1998a;Cao et al 2005).…”

Mitochondrial DNA variation and matrilineal structure in blue sheep populations of Helan Mountain, China

et al. 2006

Mitochondrial DNA (mtDNA) control region (5' hypervariable region, 554 bp) sequences from 71 samples of blue sheep (Pseudois nayaur Hodgson, 1833) collected from six study localities throughout Helan Mountain Nature Reserve in Ningxia province of China were investigated to analyse distribution patterns of genetic variability, elucidate matrilineal structure, and investigate population history. Haplotype diversity (h) among the 71 samples was estimated to be 0.792 ± 0.037, and nucleotide diversity (Å) was relatively low (0.00392 ± 0.00046). A 2 contingency analysis of all mtDNA haplotype frequencies revealed that these haplotypes were distributed in a nonrandom fashion among study localities ( 2 = 86.205, P = 0.092). Additional evidence of matrilineal structure was provided by the finding that a significant amount (9.02%; P < 0.01) of mtDNA variation was partitioned among different localities in the study area. We conclude that blue sheep of Helan Mountain Nature Reserve are structured spatially along matrilines. Pairwise computations of Èst and an AMOVA indicated that some sampling localities are differentiated relative to a random collection of genotypes and reflected differences in the spatial distribution of genetic variation. Isolation-by-distance (IBD) models (Mantel tests) revealed no obvious association between genetic differentiation and geographical distance. These results could be a basis for the development of suitable management strategies for conservation purposes. This work represents the first analysis of blue sheep mitochondrial control region DNA to be performed from a population genetics perspective.Résumé : Nous avons étudié les séquences des régions de contrôle de l'ADN mitochondrial (ADNmt) (région hypervariable 5') dans 71 échantillons de bharals de l'Himalaya (Pseudois nayaur Hodgson, 1833) prélevés dans six localités d'étude réparties dans toute la Réserve naturelle du mont Helan dans la province de Ning-hsia en Chine afin d'analyser les patrons de répartition de la variation génétique, déterminer la structure matrilinéaire et étudier l'histoire de la population. Nous estimons la diversité des haplotypes (h) dans les 71 échantillons à 0,792 ± 0,037 et la diversité des nucléotides (Å) à 0,00392 ± 0,00046, une valeur relativement basse. Une analyse de contingence de 2 de toutes les fréquences des haplotypes de l'ADNmt montre que ces haplotypes ne sont pas répartis de façon aléatoire dans les localités d'étude ( 2 = 86,205, P = 0,092). Une partie significative (9,02 %; P < 0,01) de la variation de l'ADNmt est répartie entre les différ-entes localités de la région d'étude, ce qui appuie aussi l'existence d'une structure matrilinéaire. Nous concluons que les populations de la Réserve naturelle du mont Helan sont structurées dans l'espace d'après des lignées maternelles. Les calculs paire par paire de È st et une AMOVA indiquent que certains points d'échantillonnage se différentient d'une collection aléatoire de génotypes, ce qui reflète les différences de répartition spatiale de la variation gé...

Sexual segregation is very common in sexually size dimorphic ungulates and may be the result of different habitat preferences and/or differential social behaviours of males and females. Various hypotheses have been put forward to explain this phenomenon. In the present research, we examined sexual segregation in a quite poorly understood species, the Siberian ibex. The species presents a marked sexual size dimorphism, with adult males weighing double as much as females. We use the Sexual Segregation and Aggregation Statistics (SSAS) to analyze the sex-age patterns of sexual segregation in this species, to understand the relevance of social factors. Our results show that adult Siberian ibex males were socially segregated from females all year round, except during the rutting season. Furthermore, the degree of segregation between females and males was influenced by the age of males. Moreover, the patterns of social segregation within males also increased with male age, reaching maximum values for males of 9 years-old and older, which means male age plays an important role in the sexual segregation of this species. This study clearly shows that social factors play a key role in the sexual segregation of Siberian ibex.
