O gavial (Gavialis gangeticus) é um animal criticamente ameaçado e atualmente restrito a alguns locais dispersos e isolados no Nepal e na Índia, tendo-se tornado cada vez mais raro devido a alterações do uso do solo, à redução da profundidade e do caudal do rio, à modificação da morfologia do rio, à perda de locais de nidificação e de repouso, ao aumento da mortalidade em redes de pesca destrutivas e à recolha de ovos para consumo. Os efeitos dos atributos do habitat, dos factores bióticos e das perturbações humanas na distribuição e abundância do gavial são inadequados ou completamente inexistentes, pelo que a informação sobre estes factores constitui um impedimento para compreender eficazmente as necessidades de conservação da espécie. Neste sentido, esta investigação centrou-se especialmente nos locais de repouso, na profundidade do rio e nas preferências de fluxo de água no habitat potencial do gavial, nas perturbações antropogénicas e nas implicações de conservação adequadas para a sobrevivência a longo prazo do gavial no rio Narayani, no Nepal. O livro ilustra basicamente a seleção do habitat aquático pelo gavial e, por conseguinte, é muito útil para muitas partes interessadas, especialmente para ecologistas de habitats, gestores da vida selvagem, silvicultores, etc.

    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...

    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...
