Talk Description: Scenarios can help communities think about alternative futures, but using them to drive decisions requires data. In Wisconsin’s Yahara Watershed, researchers are combining data and modelling from the Northern Temperate lakes LTER with qualitative scenarios based on trends and events from the global scenarios literature and stakeholder perspectives. The resulting assessments can help… Read more »

Legacy of acid rain: A tale of two species

Posted

Talk Description: Air pollution control efforts have succeeded in reducing sulfur dioxide and nitrogen oxide emissions, but decades of acid rain have leached calcium and magnesium from Northeastern forest soils. These changes have increased the mobility of dissolved organic matter, and possibly altered soil organic matter dynamics, altering the long-term trajectory for forest ecosystems. What… Read more »

Fire and ice: Carbon cycling feedbacks to climate in a warming Arctic

Posted

Arctic wildfire

Talk Description: About 30% of global carbon stocks reside in the vegetation and deep, carbon-rich soils of Arctic tundra and boreal forest biomes. Wildfires—which are becoming more frequent with warmer and drier weather in the Arctic—have the potential to either stabilize or accelerate regional and global warming through carbon feedbacks. By comparing the impact of… Read more »

Beyond desertification: New models for state change in drylands

Posted

Landscape in the Chihuahuan desert

Talk Description: One of the classic state-change stories is that over-grazing and drought turn grasslands into shrubby, degraded landscapes. Land managers strive to avoid such irreversible changes, using strategies based on models of how ecosystems change. But misapplication of models can lead to poor management outcomes. Researchers at the Jornada Basin LTER site and its… Read more »
