forts by an international group of soil ecologists to assess the biological and ecological mechanisms of earthworm invasions, their geographic extent and impacts on terrestrial ecosystems, and possible means by which earthworm invasions might be mitigated. .978-90-481-7366-2978-1-4020-5429-7

Earthworm invasion into previously earthworm-free temperate and boreal forests,on of the soil microflora and seedbed conditions for vascular plants. In some forests earthworm invasion leads to reduced availability and increased leaching of N and P in soil horizons where most fine roots are concentrated. Earthworms can contribute to a forest decline syndrome, and forest herbs i

Earthworm invasions of ecosystems devoid of earthworms: effects on soil microbes,e may also explain decreased mycorrhizal colonization rates, decreased mycorrhizal abundance and altered mycorrhizal morphology in the presence of earthworms. Mixing of organic layers into mineral soil during earthworm invasion tended to decrease microbial biomass in forest floor materials while inc

The influence of invasive earthworms on indigenous fauna in ecosystems previously uninhabited by eaconditions, the aggregates formed by earthworms may increase the stability of soil microclimates. Positive effects can also be seen when comminution and mucus secretion increase the palatability of unpalatable organic material for microorganisms which are the main food of most micro- and mesofaunal

Acceleration Mechanisms for Cool Star Windsor driving atmospheric expansion. We focus on the winds from low-mass, main sequence stars like the Sun, first determining the basic physical properties of thermally driven mass loss, and subsequently considering some of the ways in which rotation and magnetism can influence flow dynamics.
