The recent expansion of an avian invasive species (the Cattle Egret Ardea ibis) in Algeria
TL;DR: In this article, the authors identified new information on the recent distribution of an invasive bird species, the Cattle Egret Ardea ibis, in Algeria, and obtained from large-scale surveys in 1999 and 2007, and from historical data.
Journal ArticleDOI
Influence des éclusées hydroélectriques sur la distribution et le développement larvaire des Diptères Simuliidae d'une rivière de moyenne montagne
Régis Céréghino,Pierre Lavandier +1 more
TL;DR: Les especes de l'Oriege accomplissent leur developpement sur de courtes periodes lorsque les modifications artificielles de temperature ont peu d'incidence sur les populations of Simuliidae dont l'abondance and the composition resultent essentiellement des perturbations hydrauliques.
Journal ArticleDOI
Highly modular pattern in ant-plant interactions involving specialized and non-specialized myrmecophytes
Alain Dejean,Frédéric Azémar,Frédéric Petitclerc,Jacques H. C. Delabie,Bruno Corbara,Céline Leroy,Régis Céréghino,Arthur Compin +7 more
TL;DR: A network analysis showed that Tachia guianensis, which occurred everywhere, had its own guild of associated ant species, and its connections with the four other myrmecophytes were rare and weak, the whole resulting in a highly modular pattern of interactions with one module (i.e., subnetwork) per myRMecophyte.
Journal ArticleDOI
Convergent evolution of intraguild predation in phytotelm-inhabiting mosquitoes
TL;DR: It is shown that IGP confers a selective advantage under severe competitive conditions and results from the coadaptation of mosquito species to their specific phytotelm habitat and the presence of functionally analogous structures in different mosquito genera implies that I GP has emerged from convergent evolution in small phytolmata.
Journal ArticleDOI
An efficient semi-quantitative macroinvertebrate multimetric index for the assessment of water and sediment contamination in streams
Matteo Pallottini,Enzo Goretti,Roberta Selvaggi,David Cappelletti,Nicolas Dedieu,Régis Céréghino +5 more
TL;DR: In this article, a macroinvertebrate multimetric index that fulfills the requirements of the EU Water Framework Directive and measures ecological health as a deviation from a reference state, taking into consideration water and sediment contamination in streams of Central Italy.
