Invasive plants escape from suppressive soil biota at regional scales

Coevolution between invasive and native plants driven by chemical competition and soil biota.

Although reciprocal evolutionary responses between interacting species are a driving force behind the diversity of life, pairwise coevolution between plant competitors has received less attention than other species interactions and has been considered relatively less important in explaining ecological patterns. However, the success of species transported across biogeographic boundaries suggests...

Soil 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...

Impacts of Transgenic Plants and Micro- Organisms on Soil Biota

Little is known about the impacts of transgenic plants and micro-organisms on soil biota and processes, despite the large number of field releases of transgenic crops. Recent work has shown that transgenic plants can cause changes in the soil biota (both invertebrates and micro-organisms) associated with these plants. Often the changes are transient but their impact on the soil ecosystem remain...

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...
