Animals are often considered inconsequential regulators of nutrient cycling with some noteable exceptions (large herbivore control, insect outbreaks and earthworm activity to name a few). But how important are all animals at regulating ecosystem processes that can significantly alter nutrient dynamics? This workshop will discuss how animals impact nutrients in different ecosystems under different environmental conditions. A major goal of the workshop is to connect related research efforts across the LTER network, creating a group of participants interested in synthesizing research results collected thus far and identifying where information is scarce. Anyone studying any type of animal is encouraged to attend.
