Butterfly Movement in a Post Agricultural Landscape
(The Graduate School, Stony Brook University: Stony Brook, NY., 1-Dec-10)A central question in landscape ecology is how organisms move through fragmented landscapes. To explore this I have studied how butterflies behave at habitat borders and how readily they move through matrix (non habitat) ... -
Community Assembly Dynamics and Consequences of Invasion: Tests with the Sarracenia purpurea Model System
(The Graduate School, Stony Brook University: Stony Brook, NY., 1-May-11)The central theme of this dissertation research addresses fundamental ecological questions about community assembly (which species are found in a given place). This includes our understanding of the role of abiotic stresses ... -
The effects of habitat and predation on bay scallop populations in New York
(The Graduate School, Stony Brook University: Stony Brook, NY., 1-Aug-12)Bay scallops once supported a vibrant fishery on Long Island. Populations crashed in the mid 1980s due to a series of brown tides, and while blooms haven't occurred within the Peconic Estuary since 1995, scallops have not ... -
Effects of habitat degradation on species interactions and reproductive success in an Ecuadorian bird community
(The Graduate School, Stony Brook University: Stony Brook, NY., 1-Dec-11)Interactions between species in groups are often ignored in studies of the effects of anthropogenic change on species' persistence. However, given their global ubiquity, mixed species groups have the potential to be models ... -
Novel nonparametric approaches to stock assessment and regime shift prediction
(The Graduate School, Stony Brook University: Stony Brook, NY., 1-Dec-10)Ecosystem dynamics are often complex, nonlinear, and characterized by criticalthresholds or regime changes. Despite these difficulties, resource managers mustaccurately forecast species abundance and anticipate impending ... -
Semiparametric Bayesian modeling of density dependence
(The Graduate School, Stony Brook University: Stony Brook, NY., 1-May-12)Density dependence is a foundation of population biology. Analysis of population data with parametric models has long provided estimates of the maximum reproductive rate and the form of density dependence. These in turn ...
