Phylogeography And Postglacial Dispersal Of Smallmouth Bass (Micropterus Dolomieu) Into The Great Lakes, W. Calvin Borden, Robert A. Krebs
Phylogeography And Postglacial Dispersal Of Smallmouth Bass (Micropterus Dolomieu) Into The Great Lakes, W. Calvin Borden, Robert A. Krebs
Biological, Geological, and Environmental Faculty Publications
Refugia and dispersal routes of smallmouth bass (Micropterus dolomieu) into the Great Lakes were identified using 427 mitochondrial sequences from across their native range. Overall, smallmouth bass accessed the Great Lakes via long-distance dispersal from multiple refugia, and the distribution of genetic variation reflected the consequences of vicariant, dispersal, and paleogeological events. Proximity of lakes to glacial outlets had a greater predictive power on the resulting distribution of mitochondrial diversity relative to interbasin migration. Populations in the Eastern and Interior Highlands contained the most divergent and oldest haplotypes, reflecting their role as glacial refugia and subsequent high incidence of endemicity. …

Rap1 Is Essential For Silencing Telomeric Variant Surface Glycoprotein Genes In Trypanosoma Brucei, Xiaofeng Yang, Luisa M. Figueiredo, Amin Espinal, Eiji Okubo, Bibo Li

Trypanosoma brucei expresses variant surface glycoprotein (VSG) genes in a strictly monoallelic fashion in its mammalian hosts, but it is unclear how this important virulence mechanism is enforced. Telomere position effect, an epigenetic phenomenon, has been proposed to play a critical role in VSG regulation, yet no telomeric protein has been identified whose disruption led to VSG derepression. We now identify tbRAP1 as an intrinsic component of the T. brucei telomere complex and a major regulator for silencing VSG expression sites (ESs). Knockdown of tbRAP1 led to derepression of all VSGs in silent ESs, but not VSGs located elsewhere, and …
