No place like home? A test of the natal habitat-biased dispersal hypothesis in Scandinavian wolves
Natal dispersal is an important mechanism for the viability of populations. The influence of local conditions or experience gained in the natal habitat could improve fitness if dispersing individuals settle in an area with similar habitat characteristics. This process, defined as ‘natal habitat-bias...
