| 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 ... | 2003 | 14629350 |
