Causes and Consequences of Invasive Species; Past and Future Contributions of the LTER Network

In this country invasive species are viewed with more concern than are genetically modified organisms. While this view may change, the scientific issues associated with invasive species strongly overlap and occasionally are identical to those of genetically modified organisms. Vulnerability of native species to the introduction of novel genetic material, including swamping of gene pools,… Read more »

CANCELED-A Role for the LTER Network in the Carbon–Offset Market

Due to the unique nature of the LTER network, robust, transparent, long–term data sets from agriculture forestry and other vital terrestrial ecosystems are available, that quantify C sequestration and GHG mitigation, resulting from management practice alteration and adaptation to climate, and land–use change. There is great potential for LTER data to be utilized for environmental,… Read more »

LTER Extreme Events Working Group

Most global climate change scenarios predict an increase in the frequency and intensity of extreme weather and climate events. Ecologists and other scientists engaged in ecosystem research recognize that these extreme events will impact their systems, often with effects disproportionate to the extent and duration of the event itself. Despite the importance of extreme events,… Read more »

Synthetic Effort to Characterize the Controls on Nitrogen Transportation through Streams & Rivers

Proposal to for a workshop to assess needs for a large-scale cross-site synthetic effort to characterize the controls on nitrogen transport through streams and rivers Background Human sources now rival natural sources of fixed N to the biosphere, changing the biogeochemistry of both terrestrial and aquatic environments by adding biologically available N, primarily from fossil… Read more »
