Extinction risk of soil biota
No species lives on earth forever. Knowing when and why species go extinct is crucial for a complete understanding of the consequences of anthropogenic activity, and its impact on ecosystem functioning. Even though soil biota play a key role in maintaining the functioning of ecosystems, the vast majority of existing studies focus on aboveground organisms. Many questions about the fate of belowg...
متن کاملInteractions among Soil Biota in Coniferous Ecosystems
Fogel, R., 1988. Interactions among soil biota in coniferous ecosystems. Agric. Ecosystems Environ., 24: 69-85. The dominance of ectomycorrhizae in most coniferous forest ecosystems profoundly alters the classical concept of the role of exudation and rhizodeposition of cell fragments in the formation of the rhizosphere. In the unaltered, non-ectomycorrhizal rhizosphere the soluble exudates and ...
متن کاملBiotic replacement and mass extinction of the Ediacara biota.
The latest Neoproterozoic extinction of the Ediacara biota has been variously attributed to catastrophic removal by perturbations to global geochemical cycles, 'biotic replacement' by Cambrian-type ecosystem engineers, and a taphonomic artefact. We perform the first critical test of the 'biotic replacement' hypothesis using combined palaeoecological and geochemical data collected from the young...
متن کاملSoil Biota Reduce Allelopathic Effects of the Invasive Eupatorium adenophorum
Allelopathy has been hypothesized to play a role in exotic plant invasions, and study of this process can improve our understanding of how direct and indirect plant interactions influence plant community organization and ecosystem functioning. However, allelopathic effects can be highly conditional. For example allelopathic effects demonstrated in vivo can be difficult to demonstrate in field s...
متن کاملImpact of Grazing on Soil Biota in a Mediterranean Grassland
The effect of cattle grazing on the soil nematode and protozoan communities, and on microbial biomass, was measured in Israel’s northern highlands. Three grazing areas were compared: (1) with 1 1 cow ha 1 y ; (2) 0 55 cow ha 1 y ; and (3) control—no grazing for almost 18 years. Soil samples were collected from the upper 10 cm level of each area (n1⁄4 24), in autumn, before the onset of the rain...
