Altered moisture regimes
Changes in crop productivity as a result of shallow groundwater, Yahara Watershed, Wisconsin
Poster Number: 330 Presenter/Primary Author: Samuel Zipper A primary limitation on agricultural yields in many parts of the world, including the US Corn Belt, is the quantity and temporal distribution of water resources.
The effects of extreme heat and drought on a tallgrass prairie ecosystem
Poster Number: 310 Presenter/Primary Author: David Hoover Climate extremes, such as heat waves and drought, are expected to increase in their frequency and intensity over the next century. We examined the responses of the tallgrass prairie ecosystem
Local-scale plant species richness and the regional species pool
Poster Number: 293 Presenter/Primary Author: Kevin Wilcox Plant community structure has been shown to impact ecosystem function. However, these effects vary among ecosystems, data collection techniques, and across spatial and temporal scales.
Assessment of diatom assemblages in a subtropical karstic wetland: ecosystem-scale inference models and trajectory analysis
Poster Number: 286 Presenter/Primary Author: Sylvia Lee We developed diatom-based prediction models of hydrology and periphyton abundance to inform assessment tools for a hydrologically-managed wetland.
Biotic mechanisms contributing to the stability of productivity differ along a gradient of rainfall variability
Poster Number: 268 Presenter/Primary Author: Lauren Hallett Productivity increases with precipitation across spatial gradients but does not as closely track precipitation over time, nor does high variability in precipitation lead to highly unstable producti
