Costs of dispersal
TLDR
The consequences of the presence and magnitude of different costs during different phases of the dispersal process, and their internal organisation through covariation with other life‐history traits are synthesised with respect to potential consequences for species conservation and the need for development of a new generation of spatial simulation models.
Distinct seasonal assemblages of arbuscular mycorrhizal fungi revealed by massively parallel pyrosequencing.
TLDR
A seasonally changing supply of host-plant carbon, reflecting changes in temperature and sunshine hours, may be the driving force in regulating the temporal dynamics of AM fungal communities.
Idiosyncrasy and overdominance in the structure of natural communities of arbuscular mycorrhizal fungi: is there a role for stochastic processes?
TLDR
E ecological models derived from studies on larger organisms to microbial communities highlight that, to a first approximation, microbial communities follow similar processes and have similar patterns to those of macroorganisms, but also the need for large-scale microbial data sets, if to understand the patterns and processes regulating global biodiversity.
Relative roles of niche and neutral processes in structuring a soil microbial community
TLDR
One of the most comprehensive investigations of community-level processes acting on soil microbes is revealed, revealing a community that although influenced by stochastic processes, still responded in a predictable manner to a major abiotic niche axis, soil pH.
Dispersal evolution during invasions
TLDR
It is shown that Allee effects can slow invasion by reducing both selection for increased dispersal and chance of survival for propagules beyond the current range, which results in a more rapid spread than expected assuming evolutionary stasis.
Relative roles of niche and neutral processes in structuring a soil microbial community
Evolutionary trade-offs between reproduction and dispersal in populations at expanding range boundaries
TLDR
It is shown that increased dispersal is associated with reduced investment in reproduction in populations of the speckled wood butterfly, Pararge aegeria.
The evolution of density–dependent dispersal
TLDR
The results demonstrate that a density–dependent dispersal strategy almost always evolves and that the form of the relationship depends on reproductive rate, type of competition, size of subpopulation equilibrium densities and cost of dispersal.

TLDR
Using a spatially explicit, individual-based, evolutionary simulation model, the dispersal strategies of an organism that has only one dispersal event in its lifetime, such as a plant or sessile animal, are considered and there is a clear change in the disperseal strategies across the range.
Accelerating invasion rates result from the evolution of density-dependent dispersal.
