Project Summary This proposal is the result of collaboration initiated at the recent ASM meeting in Seattle and represents a synthesis of two workshops summarized and reported to the LTER executive committee by the lead PIs (see reports by Childers & Gross and Wilson et. Al.). The goal of this follow-up project is to foster… Read more »
Many LTER sites and research projects outside the LTER Network are demonstrating there are common patterns to land use history. However, there is major uncertainty in our understanding of the effects of land use on the global patterns of carbon and water exchange. The LTER Network is in a unique position to address this topic… Read more »
Estimating the number of species in a community or ecosystem is a fundamental problem in basic and conservation ecology. Basic researchers use biodiversity estimates to study latitudinal diversity gradients, to determine relationships between local and regional diversity, and as a response variable in manipulative experiments. Conservation ecologists use such estimates to prioritize conservation efforts (Myers… Read more »
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 »
Workshop Proposal: Biodiversity of Riparian Ecotones As ecotones between aquatic and terrestrial ecosystems, riparian zones are templates for the dynamic exchange of energy, nutrients and biological interactions. Recent studies in headwater systems have suggested that these exchanges constitute reciprocal subsidies (sensu Polis et al. 1996) between streams and terrestrial riparian habitats (Nakano & Murakami 2000;… Read more »
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 »
