Biomass Quality Responses to Selection for Increased Biomass Yield in Perennial Energy Grasses
Perennial grasses are candidates for biomass crop** systems that are focused on providing a wide range of ecosystem services in addition to sustainable bioenergy production. Switchgrass (Panicum virgatum L.) an...

A Global Meta-analysis Reveals that Nitrogen Addition Alters Plant Nutrient Concentration and Resorption in Grassland Ecosystems
Knowledge of plant nutrient strategies is crucial for defining and predicting the patterns and mechanisms resulting from nitrogen (N) deposition. However, the impacts of N enrichment on plant nutrient strategi...

Carbon, nitrogen, and phosphorus dynamics in China’s lakes: climatic and geographic influences
Given the differences in geomorphology, climate, hydrology, and human activities in various regions, lake chemometrics may also vary. However, the spatial distribution of lake chemistry and the factors affecti...

Nutrient addition and warming alter the soil phosphorus cycle in grasslands: A global meta-analysis
Grasslands are the most extensive vegetation type in the terrestrial ecosystem and have an important role in the soil phosphorus (P) cycle. Many nutrient addition and warming experiments have been conducted in...

Open AccessTesting allometric scaling relationships in plant roots
Metabolic scaling theory predicts that plant productivity and biomass are both size-dependent. However, this theory has not yet been tested in plant roots.

A global synthesis reveals more response sensitivity of soil carbon flux than pool to warming
Climate change continues to garner attention in the public sphere. Most recognize its potential to affect global carbon (C) dynamics in the biosphere. Many posit that global warming promotes the decomposition ...

Open AccessPlant composition changes in a small-scale community have a large effect on the performance of an economically important grassland pest
The grasshopper Oedaleus asiaticus Bey-Bienko (Acrididae: Oedipodinae) is a dominant and economically important pest that is widely distributed across the Mongolian plateau. This herbivore pest causes major damag...

Water infiltration influenced by agroforestry and grass buffers for a grazed pasture system
Agroforestry (AgB) and grass buffers (GB) are often adopted as alternative resource management tools in agroecosystems for environmental and economic benefits. The objective of this study was to compare the in...

Agroforestry and grass buffer effects on water quality in grazed pastures
Conservation practices including agroforestry and grass buffers are believed to reduce nonpoint source pollution (NPSP) from pastured watersheds. Agroforestry, a land management practice that intersperses agri...
