      wild boar population.

AB  - Patterns of genetic differentiation within and among animal populations might 
      vary due to the simple effect of distance or landscape features hindering gene 
      flow. An assessment of how landscape connectivity affects gene flow can help 
      guide management, especially in fragmented landscapes. Our objective was to 
      analyze population genetic structure and landscape genetics of the native wild 
      boar (Sus scrofa meridionalis) population inhabiting the island of Sardinia 
      (Italy), and test for the existence of Isolation-by-Distance (IBD), 
      Isolation-by-Barrier (IBB), and Isolation-by-Resistance (IBR). A total of 393 
      Sardinian wild boar samples were analyzed using a set of 16 microsatellite loci. 
      Signals of genetic introgression from introduced non-native wild boars or from 
      domestic pigs were revealed by a Bayesian cluster analysis including 250 
      reference individuals belonging to European wild populations and domestic breeds. 
      After removal of introgressed individuals, genetic structure in the population 
      was investigated by different statistical approaches, supporting a partition into 
      five discrete subpopulations, corresponding to five geographic areas on the 
      island: north-west (NW), central west (CW), south-west (SW), north-central east 
      (NCE), and south-east (SE). To test the IBD, IBB, and IBR hypotheses, we 
      optimized resistance surfaces using genetic algorithms and linear mixed-effects 
      models with a maximum likelihood population effects parameterization. Landscape 
      genetics analyses revealed that genetic discontinuities between subpopulations 
      can be explained by landscape elements, suggesting that main roads, urban 
      settings, and intensively cultivated areas are hampering gene flow (and thus 
      individual movements) within the Sardinian wild boar population. Our results 
      reveal how human-transformed landscapes can affect genetic connectivity even in a 
      large-sized and highly mobile mammal such as the wild boar, and provide crucial 
      information to manage the spread of pathogens, including the African Swine Fever 
      virus, endemic in Sardinia.
