Territorial status and survival in red grouse Lagopus lagopus scoticus : hope for the doomed surplus?
A previous study of survival in territorial and non-territorial red grouse Lagopus lagopus scoticus conducted between 1957 and 1967 found that territorial status in the autumn pre-determined over-winter survival. A very high proportion of territorial birds survived and virtually all non-territorial birds died or emigrated. We tested the hypothesis that over-winter survival was dependent on terr...
متن کاملLocal genetic structure in red grouse (Lagopus lagopus scoticus): evidence from microsatellite DNA markers.
Allelic variation at seven hypervariable tri- and tetranucleotide microsatellite loci was used to determine levels of population differentiation between 14 populations of red grouse (Lagopus lagopus scoticus) in northeast Scotland, UK. Despite the potential for long-distance dispersal in grouse, and a semicontinuous habitat, significant population divergence was observed (mean RST = 0.153; P < ...
متن کاملVegetation Analysis of the Territorial Boundary between Red Grouse (lagopus Lagopus Scoticus) and Ptarmigan (lagopus Mutus)
The location of the boundary between the territories of red grouse (Lagopus lagopus scoticus) and ptarmigan (Lagopus mutus) is related to the vegetation of the hills where both these species occur. If the vegetation is dominated by tall, vigorous Calluna vulgaris, grouse occur. At greater altitudes where Calluna is shorter and less vigorous, significant levels of Empetrum hermaphroditum and Vac...
متن کاملInsights into population ecology from long-term studies of red grouse Lagopus lagopus scoticus.
Long-term studies have been the backbone of population ecology. The red grouse Lagopus lagopus scoticus is one species that has contributed widely to this field since the 1950s. This paper reviews the trajectory and profound impact that these studies have had. Red grouse research has combined long-term studies of marked individuals with demographic studies over wide geographical areas and repli...
متن کاملTemporal 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 abou...
