The ecological niche concept has regained interest under environmental change (e.g., climate change, eutrophication, and habitat destruction), especially to study the impacts on niche shift and conservatism. Here, we propose the within outlying mean indexes (WitOMI), which refine the outlying mean...Contributeur (s):

Statzner, Bernhard / Doledec, Sylvain - article in peer-reviewed journal - 2011The retreat-making larvae of many lotic caddisflies build entirely new pupal cases with fine gravel and sand that they collect in the neighbourhood of the building place to fix it with silk to cobbles in swift flow (where finer sediments are generally rare). Previous field observations on...Contributeur (s):

Gallardo, Belinda / Doledec, Sylvain / Paillex, Amael / Arscott David, B. / Sheldon, Fran / Zilli, Florencia / Merigoux, Sylvie / Castella, Emmanuel / Comin Francisco, A. - article in peer-reviewed journal - 20141. Despite a general recognition that benthic macroinvertebrates respond to changes in hydrological connectivity within floodplain ecosystems, no consensus about patterns in community structure and ecosystem processes across large scales and different climates has yet been established. Such...Contributeur (s):

Statzner, Bernhard / Doledec, Sylvain - article in peer-reviewed journal - 2011When ILLIES published his concept on the longitudinal zonation of lotic invertebrates five decades ago (ILLIES, J., 1961: Internat. Rev. ges. Hydrobiol. 46: 205-213), he defined a research topic that currently interests many ecologists because he linked speciation and phylogeny with spatial...Contributeur (s):

Doledec, Sylvain / Philipps, Ngaire / Townsend, Colin - article in peer-reviewed journal - 20111. Large-scale comparative studies of ecological responses to anthropological stressors in rivers require measures that are consistent across a range of spatial scales. The biological trait profile of communities offers an alternative approach to traditional measures of macroinvertebrate taxonomic...Contributeur (s):

Doledec, Sylvain / Statzner, Bernhard - article in peer-reviewed journal - 2010Effective ecosystem management in the face of human alterations depends on our ability to quantify ecologically significant changes and to discriminate among impact levels and types. We reviewed the literature on biological responses of freshwater biota to human disturbances over the last century....Contributeur (s):

Péru, Nicolas / Doledec, Sylvain - article in peer-reviewed journal - 2010While compositional diversity is a common metric for assessing human impacts on aquatic communities, functional diversity is scarcely employed, though highly desirable from the perspective of the European Water Framework Directive. Using abundance data from 99 minimally disturbed sites (i.e., no or...Contributeur (s):

Picazo, Félix / Millan, Andrés / Doledec, Sylvain - article in peer-reviewed journal - 20121. Coleoptera species show considerable diversity in life histories and ecological strategies, which makes possible their wide distribution in freshwater habitats, including highly stressed ones such as saline or temporary waterbodies. Explaining how particular combinations of traits allow species...Contributeur (s):

Foulquier, Arnaud / Malard, Florian / Mermillod-Blondin, Florian / Montuelle, Bernard / Doledec, Sylvain / Volat, Bernadette / Gibert, Janine - article in peer-reviewed journal - 2011Groundwaters are increasingly viewed as resource- limited ecosystems in which fluxes of dissolved organic carbon (DOC) from surface water are effi- ciently mineralized by a consortium of microorgan- isms which are grazed by invertebrates. We tested for the effect of groundwater recharge on resource...Contributeur (s):
