Costs of dispersal
Dispersal costs can be classified into energetic, time, risk and opportunity costs and may be levied directly or deferred during departure, transfer and settlement. They may equally be incurredExpand

Distinct seasonal assemblages of arbuscular mycorrhizal fungi revealed by massively parallel pyrosequencing.
• Understanding the dynamics of rhizosphere microbial communities is essential for predicting future ecosystem function, yet most research focuses on either spatial or temporal processes, ignoringExpand

Idiosyncrasy and overdominance in the structure of natural communities of arbuscular mycorrhizal fungi: is there a role for stochastic processes?
1. Most studies of species abundance patterns focus on conspicuous macroorganisms while microbial communities remain relatively understudied. This bias is a concern given the functional importanceExpand

Relative roles of niche and neutral processes in structuring a soil microbial community
Most attempts to identify the processes that structure natural communities have focused on conspicuous macroorganisms whereas the processes responsible for structuring microbial communities remainExpand

The evolution of density–dependent dispersal
Despite a large body of empirical evidence suggesting that the dispersal rates of many species depend on population density, most metapopulation models assume a density–independent rate of dispersal.Expand

Dispersal evolution during invasions
Species' range expansions in response to climate change, and the invasion of exotic organisms, are two of the most pressing issues in ecology. Range expansions have already been documented in severalExpand

Evolutionary trade-offs between reproduction and dispersal in populations at expanding range boundaries
During recent climate warming, some species have expanded their ranges northwards to keep track of climate changes. Evolutionary changes in dispersal have been demonstrated in these expandingExpand

Dispersal is a key component of a species's ecology and will be under different selection pressures in different parts of the range. For example, a long-distance dispersal strategy suitable forExpand

Accelerating invasion rates result from the evolution of density-dependent dispersal.
Evolutionary processes play an important role in shaping the dynamics of range expansions, and selection on dispersal propensity has been demonstrated to accelerate rates of advance. Previous theoryExpand
