Welcome to the interactive web schedule for the 2019 Midwest Fish & Wildlife Conference! The schedule is subject to change (as of November 7, 2018). Please check back for updates. To return to the main Conference website, go to: www.midwestfw.org.

TIPS FOR NAVIGATING THIS SCHEDULE:
The conference schedule is hosted in SCHED which allows you to search within the schedule, and filter the schedule to show items only occurring on a certain date or within a track/symposia.
  • To view only a certain type of presentation or track, locate the heading "Filter By Type" in the navigation bar. As an example, try clicking on "T01: Fisheries: Great Lakes I".
  • The default view for the schedule is "Simple" which only shows the start time and title of the agenda item. Hover over the button that says "Schedule" to see the different view options. The "Expanded" option will show start and end times, room location, and session description, if there is one.
  • You can build your own schedule by creating a free account with SCHED by selecting "SIGN UP." Watch the "how-to" video to learn more about using Sched. 
  • PLEASE NOTE: Adding agenda items to your schedule through this app does not sign you up for a session. If an agenda item says "pre-registration required" or charges an additional fee, you need to add the item to your registration through the online registration system

ABSTRACT: Eastern box turtles (Terrapene carolina carolina), a declining species across most of its range, are threatened by disease events including ranaviral disease, mycoplasmosis, and herpesviral infections, but individual host hematologic responses are largely unknown. At a site with known amphibian and box turtle ranavirus outbreaks, a cohort of eastern box turtles (N=36) was investigated using radio telemetry. Location and temperature data were collected over two active seasons and brumation periods (2016-2018). Bi-weekly, turtles were sampled for blood and oral-cloacal swabs for hematology and pathogen detection. All turtles were negative for ranavirus over the study period. Total white blood cells, heterophils, lymphocytes, eosinophils, and monocytes were greater in females compared to males. Total solids, total white blood cells, heterophils, and lymphocytes showed decreasing patterns in both sexes during the active season. Home ranges and average daily movement were not significantly predicted by hematology or pathogen detection. These data add to the long-term health monitoring of eastern box turtle populations in central Illinois. With repeated measures, we have an increased ability to find complex spatiotemporal relationships between box turtle movement, hematology, and pathogens. In conjunction with long-term cross sectional surveys, a more complete picture of box turtle health related to these variables can be developed with this site as an example within central Illinois.
