Intraspecific food competition exerts powerful selective forces on all animals; successful
foragers thrive relative to weaker conspecifics. Understanding competition is therefore …

An electrofishing survey of daytime shelter microhabitat use of bullhead Cottus gobio in a
southern English chalk stream revealed positive selection for moderate water velocity …

Priority effects, ie, effects of an early cohort on the performance of a later cohort, are
generally studied between, and not within, species. The paucity of intraspecific assessments …

Many communities experience repeated periods of colonization due to seasonally
regenerating habitats or pulsed arrival of young‐of‐year. When an individual's persistence …

A field experiment during autumn, winter and spring was performed in a small stream on the
west coast of Sweden, aiming to examine the direct and indirect consequences of density …

Detailed studies of the mechanisms driving life history effects of food availability are of prime
importance to understand the evolution of phenotypic plasticity and the capacity of …

For organisms with complex life cycles, the transition between life stages and between
habitats can act as a significant demographic and selective bottleneck. In particular …

Summary 1 Integrative ecophysiological studies of closely related taxa are required to
explore the causative factors that determine species distributions, and can offer insight into …

Competition during the juvenile phase is a key process for regulating density in organisms
with high fecundity. Juvenile density-dependent bottlenecks may become even more …

Kin selection theory predicts that genetic relatedness between group members can reduce
the asymmetry in resource partitioning between superior and inferior competitors. In social …
