Spring 2019
The field of evolutionary biology is centered on the study of processes that shape the diversity of life on Earth. Processes that shape genetic variation can act on a wide-range of spatial and temporal scales. Large-scale events such as glaciations and mountain uplift have wide-ranging effects...

On the evolutionary history and population genetic structure of the North American mountain goat (Oreamnos americanus)
DownloadSpring 2012
The spatiotemporal scale at which genetic diversity is assessed can provide insights into both broad- and fine-scale patterns in ecology and evolution. I examined the distribution of genetic diversity and the evolutionary history of the North American mountain goat (Oreamnos americanus). I first...

Cullingham, Catherine I., Sperling, Felix A. H., Coltman, David W., Roe, Amanda D.
Irruptive forest insect pests cause considerable ecological and economic damage, and their outbreaks have been increasing in frequency and severity. We use a phylogeographic approach to understand the location and progression of an outbreak by the MPB (Dendroctonus ponderosae Hopkins), an...

Population structure and phylogenetic relationships of Ceutorhynchus neglectus (Coleoptera: Curculionidae)
Download2005
Sperling, F. A. H., Dosdall, L. M., Laffin, R. D.
Ceutorhynchus neglectus Blatchley is a weevil that is native to, and widely distributed in, North America. It has life-history characteristics similar to its alien invasive congener, Ceutorhynchus obstrictus (Marsham), the cabbage seedpod weevil. Our study was undertaken to compare the population...

Scaling Disturbance Instead of Richness to Better Understand Anthropogenic Impacts on Biodiversity
Download2015-01-01
Mayor, S. J., Cahill, J. F., He, F., Boutin, S.
A primary impediment to understanding how species diversity and anthropogenic disturbance are related is that both diversity and disturbance can depend on the scales at which they are sampled. While the scale dependence of diversity estimation has received substantial attention, the scale...

Tracing an Invasion : Phylogeography of Cactoblastis cactorum ( Lepidoptera : Pyralidae ) in the United States Based on Mitochondrial DNA
Download2008
Sperling, F. A. H., Simonsen, T. J., Brown, R. L.
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...
