Journal ArticleDOI
Gravel pits support waterbird diversity in an urban landscape
TL;DR: In this article, the authors assessed the benefit of 11 gravel pits for the settlement of waterbird communities in an urbanized area lacking natural wetlands and found that gravel pits captured 57% of the regional species pool of aquatic birds.
Journal ArticleDOI
Environmental factors influencing local fish species richness and differences between hydroregions in south-western France
TL;DR: In this article, the authors investigated the influence of five typological variables on the spatial distribution patterns of fish species richness in south-western France, and analyzed differences in the number of species occurring in 6 major hydroregions located within the overall study area.
Journal ArticleDOI
Patterns of rare fish and aquatic insects in a southwestern French river catchment in relation to simple physical variables
TL;DR: This work considered the spatial distribution patterns of rarity at the river catchment scale, for five freshwater taxa (fish, Ephemeroptera, Plecoptera, Trichoptera and Coleoptera) in southwestern France, showing that numbers of rare stream species increase towards downstream areas within the stream system.
Journal ArticleDOI

TL;DR: In this article, the trophic ecology of the introduced pikeperch (Sander lucioperca) in two southwestern French rivers, using stable isotope analysis, was described.
Journal ArticleDOI
Shift from a Herbivorous to a Carnivorous Diet during the Larval Development of some Rhyacophila Species (Trichoptera)
TL;DR: Gut contents analyses of each of the five larval instars of four Rhyacophila species found that all larvae started their development with a strictly phytophagous diet (diatoms and filamentous algae), and became strictly carnivorous since instar III, IV or V, depending on the considered species.
