Variability in flow as a result of seasonal precipitation patterns is a defining element of
streams and rivers in Mediterranean-climate regions of the world and strongly influences the …

Non‐native fishes are often blamed for exerting adverse ecological impacts on native fishes,
but the evidence is circumstantial and the true impacts remain largely unknown. This …

The global number of dam constructions has increased dramatically over the past six
decades and is forecast to continue to rise, particularly in less industrialized regions …

Alterations to the natural flow regime affect the structure and function of rivers and wetlands
and contribute to loss of biodiversity worldwide. Although the effects of flow regulation have …

We reviewed concepts of patch dynamics and environmental heterogeneity and their
applications to the study of fluvial ecosystems, with emphasis on research published in J …

This study analysed changes occurring in Mediterranean stream fish assemblages over a
sequence of dry years followed by a generally wet period (1991–98). Variations in …

1. A basin approximation was used to analyse distribution patterns of different components
of biodiversity (taxonomic richness, endemicity, taxonomic singularity, rarity) and …

The functional ecological guild approach is the cornerstone for the development of Indices of
Biotic Integrity and multi‐metric indices to assess the ecological status of aquatic systems …

In some arid, semi-arid or Mediterranean climate regions, increased water extraction
combined with climate change will prolong periods of drought in non-perennial streams, but …

Mediterranean endemic freshwater fish are among the most threatened biota in the world.
The Mediterranean basin has experienced substantial reductions in precipitation and water …
