Tracking, feather moult and stable isotopes reveal foraging behaviour of a critically endangered seabird during the non‐breeding season

open access: yesDiversity and Distributions, Volume 23, Issue 2, Page 130-145, February 2017., 2017
Abstract Aim The movement patterns of marine top predators are likely to reflect responses to prey distributions, which themselves can be influenced by factors such as climate and fisheries. The critically endangered Balearic shearwater Puffinus mauretanicus has shown a recent northwards shift in non‐breeding distribution, tentatively linked to ...

Qualité biologique de l’eau de mer évaluée in situ par le test embryo-larvaire de Crassostrea gigas et Mytilus galloprovincialis = In situ monitoring of sea water quality with the embryo-larval bioassay of Crassostrea gigas and Mytilus galloprovincialis [PDF]

open access: yes, 2001
Embryos and larvae of bivalves are frequently used in marine ecotoxicology for the purpose of assessing seawater quality, because they are very sensitive to pollutants and provide rapid responses.

ORCHIDEE-CROP (v0), a new process-based agro-land surface model: model description and evaluation over Europe [PDF]

open access: yesGeoscientific Model Development, 2016
The response of crops to changing climate and atmospheric CO2 concentration ([CO2]) could have large effects on food production, and impact carbon, water, and energy fluxes, causing feedbacks to the climate. To simulate the response of temperate crops to

Analysis of Wave Solutions of an Adhenovirus‐Tumor Cell System

open access: yesAbstract and Applied Analysis, Volume 2012, Issue 1, 2012., 2012
We discuss biological background and mathematical analysis of glioma gene therapy for contributing to cancer treatment. By a reaction‐diffusion system, we model interactions between gliom cells and viruses. We establish some sufficient conditions on model parameters which guarantee the permanence of the system and the existence of periodic solutions ...

Utilisation des biomarqueurs pour la caractérisation de l'état écotoxicologique des masses d'eau [PDF]

open access: yes, 2009
National audienceIn the past 25 years, numerous biomarkers have been developed with the objective to apply them to aquatic ecosystem biomonitoring. Recently, the Water Framework Directive (WFD) of the European union specified monitoring programs required

Beyond medicine: A proof of concept for synergy analysis in ecotoxicology

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 9, Page 1983-1991, September 2025.
Abstract Interactive effects among chemicals, such as synergism and antagonism, are increasingly studied in ecotoxicology and environmental research. However, these interactions are often assessed using a biased, point‐wise approach that overlooks dose‐dependent effects.
