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

NEW THIS YEAR!
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.

Species represent a wide range and combination of traits, (i.e., behavior, feeding) some of which are unique and essential to ecosystem functioning, and some which are redundant within a community. This “functional diversity” (FD) is not always mirrored by traditional measures of species richness. Here we take a trait-based approach to explore patterns of FD in fish communities across the southeastern US. We obtained species presence/absence data from the MARIS and USGS Nonindigenous Aquatic Species databases, and scored trophic traits for the 386 fish species using the Virginia Tech FishTraits Database, primary literature, USFWS reports, and fish identification texts. We calculated species richness and FD (using the functional dispersion metric) for 121 sub-basins in the southeastern US. In general, we found high functional diversity throughout the eastern highland and Appalachian regions and lower functional diversity in the Coastal Plain and Piedmont areas. Our results suggest that sub-basins with similar species richness but different FD values are likely a result of differences in river channelization, development, and habitat complexity. Going forward, we plan on relating FD to additional ecosystem health indicators (i.e., impervious surface and percent natural cover) to reveal potential correlations.
