| current and historical drivers of landscape genetic structure differ in core and peripheral salamander populations. | with predicted decreases in genetic diversity and greater genetic differentiation at range peripheries relative to their cores, it can be difficult to distinguish between the roles of current disturbance versus historic processes in shaping contemporary genetic patterns. to address this problem, we test for differences in historic demography and landscape genetic structure of coastal giant salamanders (dicamptodon tenebrosus) in two core regions (washington state, united states) versus the speci ... | 2012 | 22590604 |
| new microsatellite markers for examining genetic variation in peripheral and core populations of the coastal giant salamander (dicamptodon tenebrosus). | the coastal giant salamander (dicamptodon tenebrosus) is classified as threatened at the northern periphery of its range in british columbia (bc), canada, primarily due to forestry practices and habitat fragmentation. characterising dispersal behaviour and population connectivity is therefore a priority for this region, while genetic differentiation in core versus peripheral locations remains unstudied in this wide-ranging species. we present seven new polymorphic microsatellite markers for use ... | 2010 | 21179519 |
