| temporal changes in kin structure through a population cycle in a territorial bird, the red grouse lagopus lagopus scoticus. | populations of red grouse (lagopus lagopus scoticus) undergo regular multiannual cycles in abundance. the 'kinship hypothesis' posits that such cycles are caused by changes in kin structure among territorial males producing delayed density-dependent changes in aggressiveness, which in turn influence recruitment and regulate density. the kinship hypothesis makes several specific predictions about the levels of kinship, aggressiveness and recruitment through a population cycle: (i) kin structure w ... | 2008 | 18430149 |
