Abstract
Two projects involving the examination of complex data sets and the development of integrative models of ecological processes are proposed. Both of the projects address ecological questions of general interest and importance. One has as its primary goal the integration of biological and hydrological information to examine change in Arctic lake chemistry and productivity as it relates to indicators of global climate change. The second project involves synthesizing data from studies worldwide, including those from the Arctic LTER, in which lake nutrients have been manipulated (either experimentally increased or municipally decreased) to examine the impact of nutrients on zooplankton density and production as phytoplankton densities are altered.
