Pflanzen der Arten Acacia tortilis, Balanites aegyptiaca und Zizyphus mauritiana wurden im Forschungszentrum des IRD in Dakar hinsichtlich ihrer quantitativen Phänologie beobachtet. Der Verzweigungsprozess führt bei 9 Monate alten Pflanzen zu 4 verschiedenen Ordnungen von Wachstumseinheiten (GE) bei A. tortilis, 6 bei B. aegyptiaca und 5 bei Z. mauritiana. Die Länge und Anzahl der verschiedenen GE bei Individuen derselben Art sind ähnlich. Die GE1 ist bei A. tortilis länger und bei Z. mauritiana kürzer; bei B. aegyptiaca hat sie eine mittlere Größe. Die größte Anzahl stammt aus der GE3 bei A. tortilis (192) und der GE4 bei B. aegyptiaca (152). Die Anzahl der Blätter auf der Ebene der verschiedenen UC-Ordnungen und des Individuums ist bei A. tortilis größer. Die Schwankungen der Blattfläche pro Einheit und pro Längeneinheit bei A. tortilis und Z. mauritiana zeigen, dass die Größe eines Blattes nicht von der UC-Ordnung abhängt. Die Schwankungen sind bei B. aegyptiaca signifikant; sie zeigen einen Größenunterschied auf Blattebene. Auf individueller Ebene ist die Blattfläche bei B. aegyptiaca (268 cm²) tatsächlich hoch.

  • 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?

Marten Scheffer accessibly describes the dynamical systems theory behind cr...

    Plants of Acacia tortilis, Balanites aegyptiaca, and Zizyphus mauritiana were monitored in terms of quantitative phenology at the IRD Research Center in Dakar. The branching process results in four different orders of growth units (GU) in A. tortilis, six in B. aegyptiaca, and five in Z. mauritiana in nine-month-old seedlings. The length and number of different GUs in individua...
