Abstract:: Ecologists have long questioned why fluctuating populations tend to persist rather than go extinct. Populations that persist indefinitely are regulated by mechanisms that cause demographic density dependence, which works to bound fluctuation above zero. In a series of studies, I have sought to determine the processes and mechanisms that regulate...

These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

Abstract:: Studies of geographic variation are central to understanding ecological and evolutionary processes. Geographic variation in the shell of the black abalone (Halioth cracherodii), a marine intertidal gastropod, involves both clinal and local variation along the eastern Pacific coast in the number and size of tremata (=respiratory pores) on the shell....

Creator:: Pusack, Timothy J.
Abstract:: Because many coral-reef fishes are observable in situ, are amenable to transplantation, have small home ranges and short generation times, they provide a excellent system to investigate many topics within general ecology, fisheries biology, and conservation biology. The primary goal of this dissertation was to use the coral-reef fishes system...

Creator:: Lamb, Robert W.
Abstract:: Marine reserves are known to directly replenish overfished species. However, the community-wide effects of reserves are less clear. I examined the community of coralreef fishes in a large, fully protected marine reserve in The Bahamas: the Exuma Cays Land and Sea Park. Visual-transect surveys provided estimates and comparisons of the...
