temporal changes in allele frequencies and low effective population size in greater prairie-chickens.the number of greater prairie-chickens in wisconsin has decreased by 91% since 1932. the current population of approximately 1500 birds exists primarily in four isolated management areas. in previous studies of the wisconsin populations we documented low levels of genetic variation at microsatellite loci and the mitochondrial dna control region. here we investigate changes in genetic structure between the four management areas in wisconsin over the last 50 years. we estimated the harmonic mean e ...200415315675
contrasting patterns of mitochondrial and microsatellite population structure in fragmented populations of greater prairie-chickens.greater prairie-chickens (tympanuchus cupido pinnatus) were once found throughout the tallgrass prairie of midwestern north america but over the last century these prairies have been lost or fragmented by human land use. as a consequence, many current populations of prairie-chickens have become isolated and small. this fragmentation of populations is expected to lead to reductions in genetic variation as a result of random genetic drift and a decrease in gene flow. as expected, we found that gen ...200314629350
