Investigações realizadas em 2016, 2017 e 2018 na região de Tizi-ouzou sobre os apídeos que polinizam seis plantas de horta e uma árvore de fruto, a laranjeira, revelaram que a abelha melífera é o principal polinizador da curgete, da melancia e da laranjeira. Esta abelha é também o principal visitante da melancia, juntamente com quatro outras espécies de abelhas solitárias (Nomada sp. Ceratina saundersi, Ceratina cucurbitina e Lasioglossum pauxillum). As duas Halictidae L. pauxillum e L. malachurum parecem ser os principais polinizadores da alface e da cebola. Por outro lado, as duas leguminosas, a fava e o grão-de-bico, são polinizadas principalmente por outras espécies da família Apidae: Eucera numida, Eucera decolorata e Eucera eucnemidea. O Megachilidae Lithurgus chrysurus é também o visitante mais frequente do grão-de-bico. Os nossos resultados mostram também que a atividade forrageira das abelhas acompanha a antese das flores estudadas. Começa logo que as primeiras flores se abrem e intensifica-se à medida que o número de flores abertas aumenta.

  • 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...

    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...

    How do we explain the remarkably abrupt changes that sometimes occur in nature and society--and can we predict why and when they happen?
