Straddling temperate forests and grassland biomes and stretching along the coastline of two Great Lakes, Wisconsin contains tallgrass prairie and oak savanna, broadleaf and coniferous forests, wetlands, natural lakes, and rivers. But, like the rest of the world, the Badger State has been transformed by urbanization and sprawl, population growth, and land-use change. For decades, industry and environment have attempted to coexist in Wisconsin—and the dynamic tensions between economic progress and environmental protection makes the state a fascinating microcosm for studying global environmental change. The Vanishing Present brings together a distinguished set of contributors—including scientists, naturalists, and policy experts—to examine how human pressures on Wisconsin’s changing lands, waters, and wildlife have redefined the state’s ecology. Though they focus on just one state, the authors draw conclusions about changes in temperate habitats that can be applied elsewhere, and offer useful insights into future of the ecology, conservation, and sustainability of Wisconsin and beyond. A fitting tribute to the home state of Aldo Leopold and John Muir, The Vanishing Present is an accessible and timely case study of a significant ecosystem and its response to environmental change.

Accurately measuring denitrification in stochastic floodplains, particularly the leveed and unleveed reaches of the Mississippi River basin, requires innovative experiments. To replicate hydraulic variability ranging from overland flooding to groundwater exfiltration in floodplain wetlands, I incubated sediment cores collected from four field sites across the Dogtooth Bend of the middle Mississippi River; pairing novel deep injection (Graphic Abstract Fig. A, left) with traditional surface delivery (Graphic Abstract Fig. A, right) of both oxic and anoxic Mississippi River water. In sandy sediments with unconstrained flux of nutrients, denitrification more than doubled across a range from 192 to 429 mg N m-2 day-1 in a linear anoxic-injection hierarchy of anoxic deep > anoxic surface > oxic deep > oxic surface treatments. In contrast, for incubations in diffusion-limited clay sediments, injection type made no difference; however, in anoxic conditions denitrification rates were as high as 435 mg N m-2 day-1 compared to oxic incubations at 187 mg N m-2 day-1. This methodology reveals the magnitude of diverse denitrification rates spanning different hydrologic conditions (Abstract Fig. B) and the mediation of denitrification by sediment type. These findings provide quantified bounds to inform resource management decisions regarding what areas should be selected for protection or hydrologic reconnection to best facilitate nutrient processing services like denitrification under varying hydrologic conditions.
