LARGE-SCALE CHANGE IN PROMINENT ECOSYSTEMS

Given their size and position within watersheds, prominent ecosystems integrate conditions from the surrounding landscape, often serving as barometers of local, regional, and global-scale change. A major emphasis in limnology is to identify important mechanisms that can account for change in physically expansive (and seemingly) resilient systems. Change can viewed in terms the scale in which it manifests in natural systems such as: episodic (storms), meso-scale (hydro-period, nutrient loading), and historic (climate or the equivalent). Prominent ecosystems are unique in terms of their size (surface area, volume), their biogeochemical and species composition, and their placement within complex landscapes. Our talk will focus on describing key environmental issues in a variety of important ecosystems (lakes, rivers, wetlands, estuaries, and oceanic systems). In this way, we hope to identify unifying principles that are useful in defining why and how ecosystems respond to large-scale change.
