“…During a 10-year study, no ewes were known to emigrate or immigrate (Festa-Bianchet, 1991). The same behaviour was observed in domestic sheep by Key & McIver (1980), Lawrence & Wood-Gush (1988) and Lawrence (1990) who presented evidence that the spatial habits of the young were acquired by imitating their mothers. In this study, one mother±yearling daughter couple that used the same home range was monitored.…”

“…This has been shown from behavioural data for example in white-tailed deer Odocoileus virginianus (Nelson & Mech, 1984, red deer Cervus elaphus (Clutton-Brock et al, 1982), impala Aepyceros melampus (Murray, 1982), chamois Rupicapra sp. (Loison, Jullien & Menaut, 1999), bighorn sheep Ovis canadensis (Geist, 1971;Festa-Bianchet, 1986a,b;Rubin et al, 1998), as well as feral Soay and domestic sheep Ovis aries (Grubb & Jewell, 1974;Lawrence & Wood-Gush, 1988). Some-times this has been con®rmed from genetic studies (white-tailed deer: Chesser, 1991;Cronin, Nelson & Pac, 1991;Mathews & Porter, 1993; desert bighorn sheep: Boyce, Hedrick et al, 1997;Boyce, Ramey et al, 1999).…”

Population subdivision among mou¯on sheep Ovis gmelini ewes and ranging behaviour of rams were investigated in the Caroux-Espinouse massif (southern France). Radio-tracking data from 32 ewes and 41 rams monitored in the course of a 10-year study were used to identify female units and to document the movement patterns of males during the rutting period. Cluster analyses, based on the distance between arithmetic centres and on the degree of overlap of locations, were computed. Ewes were found to be partitioned in three or four main units to which they were faithful. Movement patterns of rams were much more variable: half were faithful to a rutting range, overlapping one or more unit(s), and the others were not. We suggest that a combination of social and spatial attachment could explain this ranging behaviour. Females build up their spatial habits following their mothers and, when adults, they occupy the area where they have been reared. Their spatial attachment is consistent with their social preferences for other females. Males balance between antagonistic spatial attachment and social preferences for other males, and differ in terms of spatial behaviour. The genetic implications are discussed.

“…Other biotic factors such as an increase in population density (Viggers and Hearn, 2005) and a decrease in vegetation cover that cause greater visibility for predators (Tufto et al, 1996) cause these animals to increase their home range. However, other studies have shown that domestic animals (Hodder and Low, 1978;Lawrence and Wood-Gush, 1988;Hoffman, 2005) and wildlife (Hulbert et al, 1996;Tufto et al, 1996) increase their home range due to a decrease in food availability.…”

“…It has been reported that Caprinae ewe groups are primarily maternal groups, comprising philopatric individuals who learn the location of escape terrain and seasonal movement patterns in their home ranges from their mothers (Geist 1971;FestaBianchet 1986;Heureux et al 1995). These ewe groups may use a given geographical area at certain times of the year (Dubois et al 1992;Boyce et al 1999), often form matrilineal social groups (Greenwood 1980;Hinch et al 1990;Heureux et al 1995), and have a comparatively stable activity range, demonstrating strong fidelity (Geist 1971;Schaller 1977;Lawrence and Wood-Gush 1988). Blue sheep ewes, like other Caprinae ewes, demonstrate gregarious and philopatric behaviours and limited dispersal ability (unpublished data).…”

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

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...
