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: Growing concern over the occurrence of harmful algal blooms has prompted efforts to reconnect coastal wetlands to Lake Erie and its tributaries in order to restore ecosystem functions and provide biodiversity support. In particular, stakeholders have collaborated to hydrologically reconnect approximately 2,397 acres of protected, diked wetlands in Ottawa National Wildlife Refuge in an effort to reduce nutrient inputs from the Maumee Area of Concern and improve habitat for economically important fisheries and wildlife. However, hydrologic connection to Lake Erie and impaired tributaries within the watershed may expose biota in previously diked wetlands to new stressors such as nutrient enrichment and invasion of non-native species. Here we examined the effect of hydrologic reconnection of diked wetlands on nutrient concentrations and macroinvertebrate biodiversity. Specifically, our objectives were to: 1) compare phosphorous and nitrogen concentrations between diked and reconnected wetlands,  2) compare taxonomic and functional trait diversity of macroinvertebrates between diked and reconnected wetlands, and 3) examine the relationships between nutrients and macroinvertebrate communities. If the reconnection of coastal wetlands had an effect on nutrient levels and macroinvertebrate communities, we predicted that 1) nutrients and macroinvertebrates would differ in reconnected and diked wetlands, and 2) macroinvertebrate communities would be impaired in wetlands with higher nutrient concentrations. We found total nitrogen was lower in reconnected wetlands, but total phosphorus was similar in reconnected and diked wetlands. All macroinvertebrate taxonomic metrics and most functional metrics were similar in reconnected and diked wetlands. Nutrient concentration gradients and yearly nutrient fluctuation, rather than wetland restoration, drove shifts in macroinvertebrate community structure.
