| mitochondrial population structure and post-glacial dispersal of longnose sucker catostomus catostomus in labrador, canada: evidence for multiple refugial origins and limited ongoing gene flow. | two hundred and eighty-seven longnose sucker catostomus catostomus were collected from 14 lakes in labrador, 52 from three lakes in ontario, 43 from two lakes in british columbia and 32 from a lake in yukon; a total of 414 in all. the resulting 34 haplotypes (20 in labrador) contained moderate haplotypic diversity (h = 0·657) and relatively low nucleotide diversity (π = 3·730 × 10(-3) . mean ϕst (0·453, p < 0·05) over all populations revealed distinct genetic structuring among c. catostomus popu ... | 2016 | 27350593 |
