Demand of all living organisms on the same nutrients forms the basis for interspecific
competition between plants and microorganisms in soils. This competition is especially …

Global climate change is already having significant impacts on arctic and alpine
ecosystems, and ongoing increases in temperature and altered precipitation patterns will …

Soil organic nitrogen (N) is a critical resource for plants and microbes, but the processes that
govern its cycle are not well-described. To promote a holistic understanding of soil N …

Abstract Theory and experiments suggest that rhizodeposition can accelerate N-cycling by
stimulating microbial decomposition of soil organic matter (SOM). However, there are …

Respiration of soil organic carbon is one of the largest fluxes of CO 2 on earth.
Understanding the processes that regulate soil respiration is critical for predicting future …

The ecosystem approach to ecology treats organisms and the physical elements of their
environment as components of a single, integrated system. This comprehensive textbook …

Generations of plant scientists have been fascinated by alpine plant life-with the exposure of
organisms to dramatic climatic gradients over a very short distance. This comprehensive text …

Languishing for many years in the shadow of plant inorganic nitrogen (N) nutrition research,
studies of organic N uptake have attracted increased attention during the last decade. The …

Ecologists are becoming increasingly aware of the role of aboveground–belowground
relationships in controlling ecosystem processes and properties. Here, we review recent …

The origins and composition of soil organic matter (SOM) are still largely uncertain.
Arbuscular mycorrhizal fungi (AMF) are recognized as indirect contributors through their …
