Dissertação (Mestrado em Ciências Biológicas - Biologia) - Universidade Federal de Goiás, Goiânia, 2009.http://repositorio.bc.ufg.br/tede/handle/tde/2621The generality of Unified Neutral Theory of Biodiversity and Biogeography was evaluated across its support for diversity structure of Odonata adults and predators, shredders and collectors insect guilds in streams. The evaluation of Neutral Theory was done in two levels of theory s hierarchical structure. One evaluation in the level of yours assumptions, the zero sum assumption, and other in the level of yours predictions to abundance models in communities and metacommunities, ZSM and logseries respectively. The variations predicted to ZSM abundance model, in accordance to dispersal limitation that community are subjected, was evaluated in insect guilds through the streams distance. In Odonata adults the dispersal limitation was evaluated indirectly through regional frequency of species body size. In this case, the ecological equivalence was restricted for body size guilds. Communities of Zygoptera adults have low density and richness within streams. Individuals distribution was grouped, not consistent to linear relation under zero sum assumption. Local abundance of Odonata adults and predators, shredders and collectors guilds didn t fit ZSM model. Geometric series models and logseries models were better in explain the abundance for all groups. Moreover, the occurrence of fit to these models isn t in according to dispersal limitation level that is expected in each region, not supporting the Neutral predictionsapplication/pdfAcesso Abertodistribuição de abundânciasOdonatametacomunidadesabundance distributionsOdonatametacommunitiesCNPQ::CIENCIAS BIOLOGICAS::ECOLOGIADissertação
