Species Distribution Modeling Of North American Odonates, Rebecca Beilinson
Species Distribution Modeling Of North American Odonates, Rebecca Beilinson
Library Map Prize
Species distribution modeling, which uses species-environment relationships to predict species’ geographic ranges, is a powerful technique for biogeographical and ecological analysis as well as for conservation planning. However, it has typically been underutilized for invertebrates and for freshwater species, as modeling these groups can pose unique challenges. Here I present methods for modeling odonate distributions and demonstrate these methods for four North American species. I show that incorporating expert-derived range maps as spatial priors can significantly improve model performance as compared to MaxEnt models. I also introduce a new distance to freshwater layer as an environmental variable, and show that …

An Investigation Of Juvenile Alewife (Alosa Pseudoharengus) Habitat Use And Growth Using Natural Markers, Gregory Norman Labonte Ms
All Student Scholarship
This research attempts to connect patterns in growth and migration of an anadromous species. The goal of this research was to understand habitat movements and growth of juvenile alewives (Alosa pseudoharengus) in the Penobscot Estuary and Bay through the use of otolith microchemistry, otolith growth increments, and a laboratory stable isotope turnover study. Understanding the connection between growth and movement of juvenile alewives may lead to more accurate and sophisticated conservation and restoration methods for anadromous species.
