Sobre IBD

Niniejsze badanie stanowi oryginalną pracę poświęconą ekobiologii wprowadzonego gatunku ryby słodkowodnej - karpia lustrzanego: Cyprinus carpio specularis Lacépède, 1803 - występującego w zbiorniku zapory Bou Hertma. Odmiana ta znalazła w tunezyjskich ekosystemach limnicznych sprzyjające warunki do rozmnażania się i zajmuje drugie miejsce po barbelu, charakteryzując się znacznym udziałem w całkowitej produkcji (29,84 %). Ekosystem zapory Bou Hertma charakteryzuje się niewielką zmiennością przestrzenną i czasową niektórych parametrów abiotycznych, co potwierdza dobrą jakość ekologiczną jego wód, które są słabo zmineralizowane, dobrze natlenione, lekko zasadowe, bardzo miękkie, stosunkowo przejrzyste i niezanieczyszczone. Przeprowadzono obserwacje morfologiczne, anatomiczne i biometryczne podgatunku Cyprinus carpio specularis. Badania płodności wykazały, że gatunek ten jest bardzo płodny - samica o standardowej długości 46,5 cm składa do 591 221 ikry.

    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...
