Spatial structure regulates and modifies processes at several levels of ecological
organization (eg individual/genetic, population and community) and is thus a key component …

1. Riverine systems consist of a mosaic of patches and habitats linked by diverse processes
and supporting highly complex communities. Invertebrates show a high taxonomic and …

Neither linear nor two‐dimensional frameworks may be the most appropriate for fish and
other species constrained to disperse within river–creek systems. In particular, the …

Biological invasions are increasingly commonplace, driven primarily by the accidental
human transport of exotic species via shipping or trade. The economic impacts can be …

Summary 1 There have been widespread changes in land use in the uplands of the UK but
the implications for dispersal of adult stages of aquatic invertebrates are poorly known. We …

Individuals in streams are constantly subject to predominantly unidirectional flow. The
question of how these populations can persist in upper stream reaches is known as the" drift …

Abstract We study a Lotka–Volterra type reaction–diffusion–advection system, which
describes the competition for the same resources between two aquatic species undergoing …

Invertebrate drift, the downstream transport of aquatic invertebrates, is a fundamental
ecological process in streams with important management implications for drift-feeding …

We consider a two-species competition model in a one-dimensional advective environment,
where individuals are exposed to unidirectional flow. The two species follow the same …

We consider a single species model and a two-species competition model in a one-
dimensional advective homogeneous environment. One interesting feature in these models …
