The genetic signature of rapid range expansions: How dispersal, growth and invasion speed impact heterozygosity and allele surfing

Lewis, Mark A. , Coltman, David W. , Goodsman, Devin W., Cooke, Barry
As researchers collect spatiotemporal population and genetic data in tandem, models that connect demography and dispersal to genetics are increasingly relevant. The dominant spatiotemporal model of invasion genetics is the stepping-stone model which represents a gradual range expansion in which...

The mating system, dispersal behavior and genetic structure of a collared pika (Ochotona collaris: Ochotonidae) population in the southwest Yukon, and a phylogeny of the genus Ochotona.
DownloadFall 2011
Pikas (Ochotona, Ochotonidae) are small, short-eared lagomorphs that inhabit steppes and mountains in northern and central Asia and alpine regions in western North America. I examined the dispersal patterns, genetic structure and mating system of a collared pika (O. collaris) population from the...

Dispersal can push population density below strong Allee thresholds ensuring the demise of small founding populations. As a result, for isolated populations of dispersing organisms, the minimum founding population size that enables establishment can be quite different from the Allee threshold. 2....

Abstract: The adventive cactus moth Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), a widely used biological control agent for Opuntia Mill. cacti, was detected in Florida in 1989. Since then, it has spread along the Atlantic and Gulf Coasts of southeastern United States, threatening...
