Parturition site selection in moose (Alces alces): evidence for social structure
Female natal philopatry has often been implicated as an important factor in moose (Alces alces) home range formation, with many populations showing behavioral evidence of sympatric home ranges among related individuals. However, previous genetic studies have failed to detect genetic subpopulation st...

We suggest that habitat structure, especially linear habitats (i.e., river valleys), or habitat bounded with barriers to dispersal, may be a factor in promoting the development of this structure. This study presents the 1st known evidence for fine-scale social genetic structure in moose and natal philopatry to calving locations in moose. In the context of natal philopatry within cervids, these findings identify several cervid-wide commonalities. Text Alces alces Alaska BioOne Online Journals Journal of Mammalogy 97 3 788 797 |
