SEAFWA 2015 has ended
Welcome to the technical sessions schedule for the 2015 SEAFWA Annual Meeting.

The technical schedule is capable of being sorted by date (i.e, Monday, Nov. 2), track (i.e. Wildlife Technical Sessions), or session (i.e. Wildlife Session #1). You can also search for a presentation title (i.e. Changing Landscapes by Coalition), key term (i.e. striped bass), or presenter last name (i.e. Weaver). The sort and search functions can be found on the navigation panel on the right side of this page. If you hover over the "Schedule" button, you’ll also see different schedule view options (i.e. Grid or Simple). Try selecting each of them to see which view you prefer. 

MY SCHEDULE FEATURE: It is not required of you to create a Sched.org account to use this site but if you do so, you’ll be able to use the "My Schedule" feature which allows you to create your own schedule for the conference. Click the "Sign Up" button in the top right corner of this page to create a Sched.org account. 

SCHEDULE UPDATES: The session abstracts and timeslots are subject to change. This site will be updated as changes come in; please check back for updates.

The southeastern United States contains one of the most diverse freshwater fish assemblages in North America. Species-habitat interactions are still poorly understood in southern coastal plain streams at the local scale, and this information is critical for the management of coastal plain assemblages. To fill in some of these data gaps we investigated the relative importance of local scale habitat covariates on fish occupancy within 264 South Carolina coastal plain stream reaches. We evaluated species-habitat relationships by developing hierarchical, multi-species models for 45 species using 3-pass depletion data collected by the South Carolina Department of Natural Resources. We also investigated covariates to detection and abundance, as well as interactions between sites and species. Modeling results suggest species-specific occupancy, abundance, and detection probabilities differ by local scale habitat covariates, and detection probabilities vary considerably across species and sites. This information provides much needed context on how assemblages are operating at the local scale.
