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: Many advances have been made over the last ten years in the field of environmental DNA, and new assays exist for a wide range of target species of interest.  As this technology matures, it is necessary to make methods more standardized to allow better comparisons across studies and enable meta-analysis of species distributions.  One key aspect where this may be possible is with assay sensitivity.  Sensitivity is a critical measure especially when comparing data from multiple markers, and it can be easily described in two measurements: Limit of Detection (LoD; the lowest concentration that can reliably be detected) and Limit of Quantification (LoQ; the lowest concentration that can reliably be quantified).  To facilitate this, an R script has been developed to allow a person with minimal R-coding ability to easily and reliably analyze their data to determine LoD and LoQ of their assays as well as automatically generate plots of their data that puts the values into context for easy understanding.  Putting eDNA assay results into a standardized framework and enabling end users to understand the results more clearly will enhance the value of eDNA data and facilitate its wider application.
