2 How to Give a TERRIBLE PowerPoint Presentation [Don t use a summary slide to keep the audience oriented throughout the presentation] 1. Make sure to put as much stuff as possible on one slide. 2. Make sure it all appears at once. 3. Use a hard to read font. 4. Make sure the text doesn t stand out from the background. 5. Don t include any pictures or other media. 6. Make sure you read each line to your audience. 7. Assume that your slides are self explanatory; don t bother to explain 8. Don t worry about content; just impress your audience with special effects.

4 Ecological Significance of the Prairie Pothole Region The Prairie Pothole region (PPR) is the northernmost extension of the Great Plains. Glacial scouring has resulted in a multitude of relatively small ponds and wetland areas, which are controlled by key aspects of the hydrologic cycle. Wetlands act as buffers to hold excess water in flood conditions. The PPR is recognized as the nesting area for the majority of the ducks that breed in the continental US. The PPR is also a migration resting point for waterfowl transiting to and from Northern Canada. Major commercial uses of the PPR include crop agriculture and cattle ranching.

29 Project Objectives 1. Quantify relationships among land use, amphibian community structure, and composition in the Prairie Pothole region. 1. Quantify relationships among physical and chemical wetland attributes on amphibian organismal and community responses. 3. Quantify the effects of multiple stressors on health and organismal responses of Rana pipiens. 4. Predict potential effects of multiple stressors on PPR wetlands and associated amphibian communities.

30 Preliminary Findings: Focal Points and Ongoing Analyses UV Radiation Attenuation in PPR wetlands does not correlate with DOC. What drives PPR UV attenuation? Malformations Data from large, randomized studies suggest qualitative and quantitative differences compared to non random studies. Land cover / Land use Regional differences in species richness exist in the PPR. Are these differences related to land use or merely reflective of geographic range limits? Community Structure R. pipiens is found in all wetlands, but prefers to breed in seasonal ponds. Is breeding success dependent on seasonal wetlands?

31 Preliminary Findings: Focal Points and Ongoing Analyses Atrazine Do low concentrations of atrazine correlate with increased gonadal dysmorphogenesis? Does amphibian community structure or breeding success respond to an atrazine gradient? Multiple Stressors R. pipiens prefers to breed in warm, shallow ponds. Will health, breeding success, and fitness be negatively impacted in semi permanent ponds with predators, pathogens, livestock? Disturbance Index Hypothesis: Habitats can be characterized based on the extent of disturbance that they are currently or have historically been subjected to.

32 Lessons Learned Scale For some parameters, e.g. atrazine, conditions in a small context predict larger landscape. not spikes, though Others e.g. chemico physical, community structure, sampling larger context is necessary. especially in cases such as PPR where communities are small Site selection Standard designations (e.g. NWI) can be inconsistent. Metrics needed for site designations (project specific?). Effort spent in the GIS lab prior to field work is never wasted. Extensive ground truthing is necessary. Flexibility and contingency planning must be built in. Unique challenges working with amphibians Amphibian life history is plastic and intimately tied to weather. Responses can appear inconsistent (actually, lack of knowledge). Night work presents logistical challenges.
