“…Several home ranges spanned both sides of those roads, and 3 radio-collared Black Bears were killed while crossing major roads. and Coster and Kovach (2012) reported similar results. Black Bears may have stayed farther away from minor roads more than expected due to high levels of disturbance during military training exercises, deer-hunting season, and land-management activities (Morrison et al 2014, van Manen et al 2012), but more data on human use of the area would be required to determine whether that was the case.…”

“…Limited dispersal is usually reflected in the spatially restricted genetic structure of the population (Peakall, Ruibal & Lindenmayer, ; Coster & Kovach, ). Our analyses showed a limited spatial extent of wild boar post‐weaning movements, which is consistent with previous reports (Truvé & Lemel, ; Keuling et al ., ).…”

Next of kin next door – philopatry and socio‐genetic population structure in wild boar

Dispersal patterns can have vital consequences for the transfer of genes in a population, thus shaping its genetic make-up and structure. Genetic relationships between individuals can, in turn, affect their social behaviour and the emergent social organization of the population. Using combination of behavioural and genetic data from the wild boar Sus scrofa population in Białowieża Primeval Forest (eastern Poland), we evaluated the socio-genetic structure of wild boar groups, the spatial genetic structure of the population and dispersal patterns. We found that wild boar post-weaning movements were largely spatially limited to the vicinity of maternal range, with female boars showing a tendency to settle in the direct neighbourhood of the kin and male boars dispersing further away from the natal area. Consequently, such dispersal patterns were reflected in the kin-based social organization and the spatial genetic structure of the population, which was manifested at a spatial scale corresponding to the size of a few home ranges (<5 km). A negative relationship between geographic distance and genetic relatedness, which was particularly strong in female boars, indicated a presence of local kin clusters dominated by female boars and the importance of female philopatry in shaping the structure of wild boar population. This was confirmed by the genetic profile and composition of social groups. This study showed the role dispersal decisions can play in the emergence of the kin-based and matrilineal social system of wild boars.

“…americanus ) make suitable study species for investigating large-scale spatial and temporal population processes in large carnivores. Spatial genetic analyses have demonstrated, for example, how results from population viability analyses of Mexican wolf ( Canis lupus baileyi ) can be combined with habitat data to develop quantitative recovery criteria for population connectivity [5]; they have also revealed important geographic mixing areas for different brown bear subpopulations [6], cryptic brown bear phylogeographical patterns [7], and have demonstrated the impacts of anthropogenic forces on the spatial genetic structure of black bear populations [8]. Although a set of methodological approaches have been developed in spatial genetics over the last decade (reviewed in 9), the field would benefit from further conceptual and methodological advancement.…”

Spatial genetics is a relatively new field in wildlife and conservation biology that is becoming an essential tool for unravelling the complexities of animal population processes, and for designing effective strategies for conservation and management. Conceptual and methodological developments in this field are therefore critical. Here we present two novel methodological approaches that further the analytical possibilities of STRUCTURE and DResD. Using these approaches we analyse structure and migrations in a grey wolf ( Canis lupus ) population in north-eastern Europe. We genotyped 16 microsatellite loci in 166 individuals sampled from the wolf population in Estonia and Latvia that has been under strong and continuous hunting pressure for decades. Our analysis demonstrated that this relatively small wolf population is represented by four genetic groups. We also used a novel methodological approach that uses linear interpolation to statistically test the spatial separation of genetic groups. The new method, which is capable of using program STRUCTURE output, can be applied widely in population genetics to reveal both core areas and areas of low significance for genetic groups. We also used a recently developed spatially explicit individual-based method DResD, and applied it for the first time to microsatellite data, revealing a migration corridor and barriers, and several contact zones.
