L’augmentation continue de la population humaine et la pression qu’elle exerce sur l’utilisation des terres constituent une grave préoccupation dans de nombreux pays en développement. Dans certaines parties du monde, la croissance démographique, le développement industriel et la sécurité alimentaire ont entraîné une pression pour l’utilisation de terres agricoles marginales contenant des niveaux relativement élevés de radioactivité. En Égypte, de nombreuses localités de sable noir le long de la côte méditerranéenne sont utilisées pour de nombreuses cultures. Les sables de la côte méditerranéenne contiennent différentes concentrations de fractions de minéraux lourds. Les minéraux lourds sont caractérisés par des concentrations élevées de thorium et d’uranium dans leur structure cristalline. L’étude des oligo-éléments dans les matrices biologiques, agricoles, industrielles et environnementales a pris une importance considérable en raison de leur rôle dans les questions de santé. La radioactivité naturelle du sol provient principalement des séries de l’uranium et du thorium et du potassium naturel. L’étude du transfert de l’uranium et du thorium du sol aux plantes comestibles par l’absorption racinaire est associée aux chaînes alimentaires.

  • 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...

  • Modeling Populations of Adaptive Individuals
    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...

    Carlos Martínez del Rio / William H. Karasov
    Unlocking the puzzle of how animals behave and how they interact with their environments is impossible without understanding the physiological processes that determine their use of food resources. But long overdue is a user-friendly introduction to the subject that systematically bridges the gap between physiology and ecology. Ecologists--for whom such knowledge can help clarif...
