genetic variation within and among fragmented populations of lesser prairie-chickens (tympanuchus pallidicinctus). | as a result of recurrent droughts and anthropogenic factors, the range of the lesser prairie-chicken (tympanuchus pallidicinctus) has contracted by 92% and the population has been reduced by approximately 97% in the past century, resulting in the smallest population size and most restricted geographical distribution of any north american grouse. we examined genetic variation through dna sequence analysis of 478 base pairs of the mitochondrial genome and by assaying allelic variation at five micr ... | 2003 | 12675823 |
