Die Anwendung von Mikrosatelliten zum Studium der Sozialstruktur bei Großsäugetieren : am Beispiel von italienischem Wolf und Damwild
Scandura M. The use of microsatellites in the study of social structure in large mammals : Italian wolf and fallow deer as case studies. Bielefeld (Germany): Bielefeld University; 2004.The content of the present PhD thesis deals with the application of microsatellite analysis to the study of two species of large mammals, referring to some aspects of their social and mating systems. The Italian wolf (Canis lupus) and the fallow deer (Dama dama) were chosen as case studies, since genetic investigations on their populations result, for different reasons, problematic.
The wolf in Italy is a particularly protected species, recovering throughout the peninsula from the effects of a recent bottleneck. Sampling wolves may not rely on capturing or killing them, therefore an alternative, non-invasive, approach was adopted in my study. Scats, shed hairs and blood drops collected on the snow represented the main source of DNA for the analysis. Methodological cares were necessary to obtain reliable wolf genotypes. A set of ten canine microsatellites was employed to achieve unique multilocus genotypes in the population. Fifty-two individuals were typed in the period 1998 - 2003. In some cases, pack composition was determined, confirming that familiar bonds are at the basis of wolf social units. An unpredictable high local differentiation was found among geographic areas. Early dispersal seem to be common in the population, but its effects on the gene flow are not detectable, at least at my study scale. I proposed that most of this dispersal may be unsuccessful or over long distances. The study population, indeed, seem to have reached a high level of local saturation, with clumped pack territories and high reproductive rates, and thus possibly represents a source, from which wolves disperse toward sink areas.
The second study involves an enclosed population of fallow deer. Lekking is seldom observed in mammals, and among them, it is more common in ungulate species. Fallow deer is one of the most studied lekking ungulate and this particular population is object of long-term researches on male mating strategies. Mature bucks in the population join into leks during the breeding season: a costly strategy, which apparently does not guarantee high direct benefits (fitness). In this study, for the first time, I used a molecular approach to verify the existence of a genetic basis to lek formation. The recourse to microsatellites enabled to overcome the strong limitation due to the extremely monomorphism of the species, documented in several studies. Though the low variability even at microsatellite loci, the hypotheses of kin selection (territorial bucks in a lek are relatives) and of heterozygosity advantage (territorial bucks in a lek have an overall high heterozygosity) were tested and resulted not supported by data. Hence, future studies should be addressed towards phenotypic variation and consider in detail physiological and ecological factors, in order to clarify the reasons why lekking takes place in fallow deer
Maintaining differentiation without geographic isolation in the North American gray wolf
A common element of speciation models is geographic isolation. However, this requirement presents a problem
for differentiation and related speciation of large carnivorous mammals that can disperse over long distances. The
gray wolf is the most vagile terrestrial vertebrate species, and record dispersal events have been observed.
Consequently, even widely separated populations are poorly differentiated. Wolves are generally described as
territorial year-round. However, some populations of tundra and taiga-living wolves are reported to migrate over
distances of hundreds of kilometres, and to be paler in coloration. Using satellite telemetry, we show that tundra
wolves (n=19) follow barren ground caribou (n=19) on their 1500-kilometre annual migration. We also analysed
genetics and coloration in tundra, taiga and boreal forest wolves (n=258, n=82 and n=64 respectively). Although
tundra/taiga wolves overlap with forest conspecifics during the winter breeding season, they were differentiated
from them and had Fst values of 0.30, 0.04, and 0.07 for mitochondrial, microsatellite and Y-chromosome markers
(p<0.001 in all cases). Further, 93% of tundra/taiga wolves had a pale coloration whereas only 38% of forest wolves
did (X2=85, p<0.0001). We suggest that specialization on migratory prey and selection for pale coloration in snow-
covered habitats provide the basis for reproductive isolation. Tundra/taiga migratory and boreal forest territorial
wolves are distinct but interconnected conservation entities. Hunting impacts on wolves may be substantial in areas
where migratory and resident individuals congregate seasonally. Such impacts should be evaluated for the two
ecotypes of wolves, and opportunities for migration should be maintained

Use of satellite images for broad-scale modelling of conservation areas for wolves in the Carpathian Mountains, central Europe
This study analysed the spatial structure of the Carpathian Mountains, in Central Europe, considering it a unit that extends across national boundaries, and assessing the suitability of areas were wolves could be conserved. Physical characteristics of the area were extracted from NOAA-AVHRR NDVI. A set of 9 images from different periods of the year was used to parameterise the phenological variability of the area. Digital maps of road networks, human settlements and a DEM were integrated in a GIS. Locations of wolf presence
were used to extract “optimal” environmental characteristics that served as reference for estimating the degree of suitability over the whole area. Results show that most of the Carpathian Mountains are highly suitable for the wolf and that highly suitable areas are actually inhabited by the present population of wolf. These are also the area most phenologically stable
