Because research on nematode involvement in trophic interactions, foodweb structure, and biodiversity is constrained by lack of an overview of nematode feeding habits, this outline presents a…
Open‐top designs for manipulating field temperature in high‐latitude ecosystems
Passive open‐top devices have been proposed as a method to experimentally increase temperature in high‐latitude ecosystems. There is, however, little documentation on the efficacy of these devices.…

LOW‐DIVERSITY ANTARCTIC SOIL NEMATODE COMMUNITIES: DISTRIBUTION AND RESPONSE TO DISTURBANCE
The nematode community structure of 1–3 species in two functional groups may be the simplest soil food web of any terrestrial ecosystem, suggesting that Antarctic soil ecosystems are sensitive to anthropogenic disturbance.
Biodiversity and ecosystem functioning in soil
The soil biota considered at present to be most at risk are species-poor functional groups among macrofaunal shredders of organic matter, bioturbators of soil, specialized bacteria like nitrifiers and nitrogen fixers, and fungiforming mycorrhizas.

Source-sink carbon relations in two Panicum-coloratum ecotypes in response to herbivory
Population samples of an African C4 grass were collected from two locations in the Serengeti Grasslands varying in grazing intensity, suggesting the evolution of physiological traits related to C assimilation, translocation, and storage in response to previous grazing history.
Anhydrobiotic coiling of nematodes in soil.
It appeared that induction of coiling and anhydrohiosis were determined by the physical forces exerted by the water film surrounding the nematode, which, for these three species, was 6-9 monomolecular layers of water, rather than the % moisture and relative humidity of the soil per se.
The spatial distribution of nematode trophic groups across a cultivated ecosystem
Results suggest that important soil food web components are strongly patterned at sub- hectare scales in this site, and suggests that such patterning may be even more common in less-disturbed sites.
