متن کاملThe light : nutrient ratio in lakes: a test of hypothesized trends in bacterial nutrient limitation
Thomas H. Chrzanowski and James P. Grover Department of Biology, The University of Texas at Arlington, PO Box 19498, Arlington, TX 76019, U.S.A. E-mail: [email protected] Abstract The light-to-nutrient hypothesis explores how the balance between energy (as light energy) and nutrients (as total phosphorus) shapes aquatic ecosystem structure and process. The balance of energy and nutrients is thought ...
متن کاملNitrogen:phosphorous supply ratio and allometry in five alpine plant species
In terrestrial ecosystems, atmospheric nitrogen (N) deposition has greatly increased N availability relative to other elements, particularly phosphorus (P). Alterations in the availability of N relative to P can affect plant growth rate and functional traits, as well as resource allocation to above- versus belowground biomass (MA and MB). Biomass allocation among individual plants is broadly si...
متن کاملNutrient cycling in an Alpine tundra ecosystem on Changbai Mountain, Northeast China
Nutrient availability regulates the responses of high-latitude ecosystems to climate change but nitrogen, phosphorus and sulfur biogeochemistry, especially, phosphorus and sulfur cycles, are poorly understood in Alpine tundra ecosystem. This study examines the cycling of nutrients in a 302-year-old Alpine tundra ecosystem in which litter has accumulated through compartment methods. Samples of t...
