Vegetation 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 کاملGenetic diversity and management of Nearctic rock ptarmigan (Lagopus mutus)
Though the rock ptarmigan, Lagopus mutus (Montin, 1776), is a relatively common breeding bird in arctic regions worldwide, several Nearctic insular populations have become extinct or threatened in the past 250 years. In this study, we use patterns of DNA sequence variation in the mitochondrial control region and a nuclear intron (GAPDH) to reexamine the evolutionary history of Nearctic rock pta...
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 کاملSequence Polymorphism in Candidate Genes for Differences in Winter Plumage between Scottish and Scandinavian Willow Grouse (Lagopus lagopus)
BACKGROUND Population variation in the degree of seasonal polymorphism is rare in birds, and the genetic basis of this phenomenon remains largely undescribed. Both sexes of Scandinavian and Scottish Willow grouse (Lagopus lagopus) display marked differences in their winter phenotypes, with Scottish grouse retaining a pigmented plumage year-round and Scandinavian Willow grouse molting to a white...
