We reviewed the literature on the effects of land use changes on mediterranean river
ecosystems (med-rivers) to provide a foundation and directions for future research on …

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 …

We examine evidence for the structuring of fish communities from stream and lake systems
and the roles of biotic, abiotic, and spatial factors in determining the species composition …

1. Landscape ecology deals with the influence of spatial pattern on ecological processes. It
considers the ecological consequences of where things are located in space, where they …

Traditionally, threatened species management has emphasized conservation of individual
populations and has assumed that abundance within suitable habitats is primarily governed …

Some studies suggest that lotic populations of brown trout (Salmo trutta) are regulated
through density‐dependent mortality and emigration to the extent that mean growth rates of …

We evaluate the goals of meta‐analysis, critique its recent application in ecology, and
highlight an approach that more explicitly links meta‐analysis and ecological theory. One …

Aim We examined the relative contributions of spatial gradients and local environmental
conditions to macroinvertebrate assemblages of boreal headwater streams at three …

Lentic macroinvertebrates have received comparatively little interest from lake managers
and researchers for two reasons. First, with few exceptions (eg, the control of mosquitos, the …

This paper summarizes and synthesizes the collective results that emerged from the series
of papers published in this issue of J-NABS, and places these results in the context of …
