1. Read Trebitz and Hoffman (2015) and be prepared to discuss the items below. [Dr. Cooper’s slides will be here following his presentation.]

    Coastal Wetland Support for Great Lakes Fisheries …

    • What big question/idea is being addressed in the paper?
    • Why did the authors feel that the study was important?
    • Write out the specific questions/hypotheses addressed.
    • What data were used to address these hypotheses?
    • How did the authors identify coastal wetland species that support Great Lakes commercial and recreational fisheries?
    • Check out that Evaluating wetland associations… section. Yeah, lots of complex stats in there! But in general, what were the goals of these difficult analyses?

    Results (The Results in this paper are much easier to read than the Methods!)

    • Which wetland species appeared to provide “direct fisheries support” in the Great Lakes? Why is it “direct support?”
    • Which wetland species provide “indirect fisheries support” in the Great Lakes? Why is it “indirect?”
    • Which commercially important species show up in Great Lakes coastal wetlands as larvae?
    • What as the one consistent life history trait among the common coastal wetland species?
    • The ordination results (NMDS) are tough to understand. However, what pattern (“axis of variation””) did they mention? In other words, fish community structure tended to correlate with …?

    Discussion

    • Did the authors answer their Big Questions? In other words, were they able to identify metrics of fisheries support?
    • What about their Specific Questions? In other words, did they identify species that provide fisheries support? How did wetland condition affect fisheries support?
    • What do the authors think of using a “poster child species” to represent coastal wetland support of fisheries? Why?
    • The authors found that ~50% of the commercial and ~80% of the recreational fishery harvest in the Great Lakes is accounted for by wetland-using species. Is this a good argument for preserving/restoring coastal wetlands? Why and why not?
