Consumer-mediated nutrient dynamics of marine ecosystems under the wake of global change Increases in the frequency and severity of disturbance events as a result of global change are altering population and community dynamics of marine animals. Given that animals are key recyclers of nutrients in many ecosystems, these ecological impacts may have consequences for ecosystem… Read more »

The Flux Gradient Project: Understanding the methane sink-source capacity of natural ecosystems While biogenic CH4 emissions are thought to be of a similar magnitude to anthropogenic emissions, biogenic emissions remain the most uncertain source of the global CH4 budget. The vast areas with relatively small uptake and emission rates have been largely understudied but could… Read more »

Interannual variability and long term change in pelagic community structure across a latitudinal gradient Recent synthesis has shown both similarities and differences in how pelagic marine ecosystems have been influenced by cyclic and long term changes in the marine environment. The pelagic community structure synthesis group uses comparative data to test a series of conceptual… Read more »

Response of Primary Producers and Primary Consumers to Environmental Change: from small-scale disturbances to seasonal and long-term changes This LTER SPARC Synthesis Working Group brings together LTER researchers interested in understanding how disturbances and environmental change across timescales are altering the production and transfer of organic matter from primary producers to herbivores. All ecosystems are… Read more »

Do actively cycling C and N pools depend ultimately on soil P supply? Across-biome synthesis In terrestrial systems the nitrogen cycle is more open than the phosphorus cycle. New N accumulates by biological N fixation and atmospheric deposition, and is readily lost from the system when N is in excess of biological demand. In contrast,… Read more »
