Broken barriers: Human‐induced changes to gene flow and introgression in animals

摘要: We identify two processes by which humans increase genetic exchange among groups of individuals: affecting the distribution and dispersal patterns across a landscape, interbreeding sympatric or parapatric groups. Each these might then have different effects on biodiversity: changes in number taxa through merging splitting groups, extinction/extirpation fitness. review various ways are exchange, highlight difficulties predicting impacts biodiversity. Gene flow hybridization crucially important evolutionary forces influencing Humans alter natural myriad ways, anthropogenic likely to influence integrity populations species. argue that taking gene-centric view towards conservation will help resolve issues pertaining management.
