Background Knowledge of biological and climatic controls in terrestrial nitrogen (N) cycling
within and across ecosystems is central to understanding global patterns of key ecosystem …

In the fungal kingdom, the ectomycorrhizal (EcM) symbiosis has evolved independently in
multiple groups that are referred to as lineages. A growing number of molecular studies in …

Explaining the large-scale diversity of soil organisms that drive biogeochemical processes—
and their responses to environmental change—is critical. However, identifying consistent …

Boreal forest soils function as a terrestrial net sink in the global carbon cycle. The prevailing
dogma has focused on aboveground plant litter as a principal source of soil organic matter …

The supply of nitrogen commonly limits plant production in boreal forests and also affects
species composition and ecosystem functions other than plant growth. These interrelations …

The ectomycorrhizal (EcM) symbiosis involves a large number of plant and fungal taxa
worldwide. During studies on EcM diversity, numerous misidentifications, and contradictory …

In this review, we synthesize field and culture studies of the 15N/14N (expressed as δ15 N)
of autotrophic plants, mycoheterotrophic plants, parasitic plants, soil, and mycorrhizal fungi …

Despite the major importance of soil biota in nutrient and energy fluxes, interactions in soil
food webs are poorly understood. Here we provide an overview of recent advances in …

Collembola are among the most abundant, diverse and functionally important groups of soil
animals. Collembolans inhabit different litter and soil layers and their food objects are …

Stable carbon isotopes are used extensively to examine physiological, ecological, and
biogeochemical processes related to ecosystem, regional, and global carbon cycles and …
