Les matières fertilisantes d’origine résiduaire (Mafors) sont utilisées dans l’agriculture comme amendement organique du sol pour améliorer sa structure, sa fertilité et son activité biologique. En France, les effluents d’élevage représentent la grande majorité des Mafors épandues, suivis des boues urbaines et industrielles ainsi que des composts. ...
Les effets observés et prédits du réchauffement climatique placent les études sur la biologie thermique au cœur des travaux sur le vivant. La température est en effet connue pour influencer quasiment tous les paramètres des ectothermes tels que les insectes. Cette thèse sur la biologie thermique du ravageur de culture Spodoptera littoralis est basé...
The developmental period is a very sensitive phase since it sees the synthesis and maturation of all organs and functions of the future organism. Therefore, any disruption experienced early in life may have substantial subsequent consequences. In the context of the considerable impact of Human activities on wildlife, seabirds are particularly at ri...
En produisant un peu plus de 158 000 tonnes de nickel (Ni) par an la Nouvelle-Calédonie fait partie des producteurs de Ni les plus importants au monde avec des sols riches en éléments traces métalliques. Cette exploitation massive de Ni est un enjeu économique majeur pour le pays (8 à 17 % du PIB annuel) au détriment de potentiels impacts environne...
peer reviewed / Rotifers are ubiquitous aquatic organisms which form one of the most populous zooplankton classes. Their efficient grazing of phytoplankton and high reproduction and turnover rates enable rapid nutrient cycling which feeds the upper levels of the food chain, making them a vital element of aquatic ecosystems. Furthermore, their small...
In agricultural areas, ponds are suitable wetland environments to dissipate and reduce the occurrence of pesticides in aquatic environments. However, their impact at a catchment scale is still poorly understood. This study aims to determine how these organic contaminants were trapped in a pond located in an agricultural critical zone from SW France...
Short-chain chlorinated paraffins (SCCPs) are organic alkane formulations that are released in the environment by industrial processes and electronic waste. They are widely dispersed by wind and water, and therefore have been found in numerous ecosystems and organisms worldwide, where they are not readily biodegradable. This long environmental half...
Graphene-based nanomaterials (GBMs), such as graphene oxide (GO) and reduced graphene oxide (rGO), possess unique properties triggering high expectations for the development of new technological applications and are forecasted to be produced at industrial-scale. This raises the question of potential adverse outcomes on living organisms and especial...
Short-chain chlorinated paraffins (SCCPs) are organic alkanes with numerous industrial applications which are also present in some electronic devices. They are widely dispersed by wind and water, and therefore have been found in aquatic ecosystems worldwide, where they are not readily biodegradable. Organisms may thus be exposed to them in a wide r...
