Animal nitrogen swap for plant carbon
Article Abstract:
Observations are presented describing how a common boreal tree species is able to act indirectly as a predator of arthropods living in the soil, because a fungal symbiont uses the plant's carbon in exchange for its own animal nitrogen. This reveals a more flexible and efficient nitrogen cycle than has been assumed, and indicates the possibility that forest-nutrient cycling is more tightly linked and complicated than scientists believe.

Abrupt rise in atmospheric CO (sub) 2 overestimates community response in a model plant-soil system
Article Abstract:
The ecological effect of increasing atmospheric CO (sub) 2 concentration, CO (sub) 2, usually involves exposing today's ecosystems to expected future CO (sub) 2 levels. However, a major assumption of these approaches has not been tested that exposing ecosystems to a single-step increase in CO (sub) 2 will yield similar responses to those of a gradual increase over several decades.

Rise in carbon dioxide changes soil structure
Article Abstract:
It is shown that water stability and size distribution of aggregates is affected by long-term CO(sub2) fumigation, in three ecosystems. A mechanism for this is proposed involving the production of the glycoprotein glomalin by fungi. It is suggested that changes in soil structure in response to CO(sub2) enrichment should be included in global research.
