| the effect of the last glacial age on speciation and population genetic structure of the endangered ethiopian wolf (canis simensis). | during the last glacial age, afro-alpine habitats were widespread across the highlands of ethiopia. a wolf-like canid ancestor is thought to have colonized this expanding habitat and given rise to a new species that was remarkably well adapted to the high altitude environment: the ethiopian wolf canis simensis. here, we address the timing of genetic divergence and examine population genetic history and structure by investigating the distribution of mitochondrial dna (mtdna) sequence variation. t ... | 2004 | 15245401 |
