Lo studio volto a stimare la biodiversità delle api selvatiche, condotto presso l’Università di Kinshasa, in particolare nei pressi della Facoltà di Scienze e nel giardino sperimentale della stessa facoltà, nel periodo compreso tra il 17 maggio 2009 e il 30 maggio 2010, consisteva, in primo luogo, nel determinare la diversità di questa apidofauna e, in secondo luogo, nel conoscere la fenologia delle api selvatiche. Sono stati catturati in totale 59 esemplari, raggruppati in 17 specie e 8 generi, e poi suddivisi in 3 famiglie. Secondo l’indice di diversità di Shannon-Weaver (H’), l’aspettativa di Hulbert e l’indice di equità di Pielou (E), il nostro sito di studio presenta un’elevata diversità, il che, dal punto di vista ecologico, riflette l’equilibrio dell’ambiente (H’: 4 bit, E: 0,91 ed Es: 16,03 specie/100 esemplari). Per quanto riguarda la fenologia delle famiglie di api selvatiche, essa rivela che le loro popolazioni variano a seconda dei mesi e dipendono anche dai fattori ambientali e dalla disponibilità di risorse floreali. Tuttavia, tali popolazioni sono ben rappresentate nel mese di maggio, quando si osserva la fioritura di un numero massimo di specie vegetali.

    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...

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