Sobre IBD

Les écosystèmes côtiers méditerranéens, et particulièrement le golfe d’Annaba, subissent une pression anthropique croissante. Cet ouvrage développe et valide une méthode de dosage des métallothionéines chez Perna perna, moule sentinelle native, et évalue la réponse intégrée de biomarqueurs biochimiques (MTs, GSH, GST) face au cadmium et au cuivre. Soixante-dix individus prélevés au cap de Garde ont été exposés in vivo à trois concentrations de chaque métal. Les résultats révèlent des stratégies de détoxication distinctes : le cuivre induit une hyperaccumulation des MTs dans les branchies à forte dose, tandis que le cadmium génère une induction différée dans le corps, couplée à une déplétion du GSH. Cette approche multi-biomarqueurs et multi-compartiments discrimine les mécanismes de toxicité et offre une base pour le diagnostic intégré de la contamination métallique dans le golfe d’Annaba.

  • Water from a Transdisciplinary Perspective
    Ana Isabel Pereira Cardoso / Teresinha M. Gonçalves
    Life in cities has distanced human beings from nature and made it difficult to understand the ecology of life dependent on the environment. Urban water collection and distribution processes contribute significantly to the fragmentation of knowledge and the vital recognition of the water cycle. Without the effective participation of the subject in environmental actions, it is no...

    Bret C. Harvey / Steven F. Railsback
    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...
