LTER at AGU 2023
The LTER always has a huge presence at AGU, and this year is no different. See all the LTER related talks at this page.

Lightning Talks from the 2023 Science Council Meeing.
Symposium: Discovering the Nature of Ecosystem Change
Synopsis Even as sea-level rise, drought, and fire increase pressures on some ecological systems, others are benefitting from protection and restoration efforts. But some changes are not reversible. Long-term research employs observations of past changes, together with long-running experiments and modeling to understand the processes responsible for sustaining ecological functions. Drawing on concrete examples and… Read more »
Plausible freshwater futures: Yahara watershed, Wisconsin, USA
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
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
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
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 »
Climate-Resilient Coasts: How long-term research and restoration informs management
Talk Description: Coastal habitats are the first line of defense against sea-level rise and storms. At the same time, they are vulnerable to change, and can be pushed past tipping points and lost. A long-term, landscape-scale experiment with seagrass at Virginia Coast Reserve LTER is the first of its kind to show the role of… Read more »
