| landscape influences on dispersal behaviour: a theoretical model and empirical test using the fire salamander, salamandra infraimmaculata. | when populations reside within a heterogeneous landscape, isolation by distance may not be a good predictor of genetic divergence if dispersal behaviour and therefore gene flow depend on landscape features. commonly used approaches linking landscape features to gene flow include the least cost path (lcp), random walk (rw), and isolation by resistance (ibr) models. however, none of these models is likely to be the most appropriate for all species and in all environments. we compared the performan ... | 2014 | 24648023 |
