Plântulas de Acacia tortilis, Balanites aegyptiaca e Zizyphus mauritiana foram acompanhadas em termos de fenologia quantitativa no Centro de Investigação do IRD em Dakar. O processo de ramificação resulta em 4 ordens diferentes de unidades de crescimento (UC) em A. tortilis, 6 em B. aegyptiaca e 5 em Z. mauritiana em plantas com 9 meses de idade. O comprimento e o número das diferentes UC em indivíduos da mesma espécie são semelhantes. A UC1 é mais longa em A. tortilis e mais curta em Z. mauritiana; tem um tamanho intermédio em B. aegyptiaca. O número maior provém da UC3 em A. tortilis (192) e da UC4 em B. aegyptiaca (152). O número de folhas à escala das diferentes ordens de UC e do indivíduo é mais importante em A. tortilis. As variações da superfície foliar unitária e por unidade de comprimento em A. tortilis e em Z. mauritiana indicam que o tamanho de uma folha não depende da ordem das UC. As variações são significativas em B. aegyptiaca; elas revelam uma diferença de tamanho ao nível de uma folha. Na escala do indivíduo, a área foliar é elevada em B. aegyptiaca (268 cm²).

  • 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...

    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?

    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...
