Anthropogenic nitrogen deposition predicts local grassland primary production worldwide
Humans dominate many important Earth system processes including the nitrogen (N) cycle. Atmospheric N deposition affects fundamental processes such as carbon cycling, climate regulation, and biodiversity, and could result in changes to fundamental Earth system processes such as primary production. Both modelling and experimentation have suggested a role for anthropogenically altered N depositio...
متن کاملNitrogen deposition weakens plant-microbe interactions in grassland ecosystems.
Soil carbon (C) and nitrogen (N) stoichiometry is a main driver of ecosystem functioning. Global N enrichment has greatly changed soil C : N ratios, but how altered resource stoichiometry influences the complexity of direct and indirect interactions among plants, soils, and microbial communities has rarely been explored. Here, we investigated the responses of the plant-soil-microbe system to mu...
متن کاملLong-term persistence of pioneer species in tropical rain forest soil seed banks.
In tropical forests, pioneer tree species regenerate from seeds dispersed directly into canopy gaps and from seeds that persisted in soil seed banks before gap formation. Life-history models have suggested that selection for the long-term persistence of tree seeds in the soil should be weak because persistence potentially reduces population growth rate by extending generation time and because a...

متن کاملThe composition of seed banks on kangaroo rat (Dipodomys spectabilis) mounds in a Chihuahuan Desert grassland
Disturbance is a major factor determining the plant community structure of ecological systems. In particular, small-scale disturbances from animals can increase heterogeneity and species diversity in plant communities. Kangaroo rat (Dipodomys spectabilis) mounds are small-scale disturbances that support unique plant communities compared to surrounding habitats. The seed bank, which is usually a...
