Resumo

A defaunação consiste na diminuição da diversidade e/ou biomassa de espécies animais como resultado direito da caça e/ou fragmentação do habitat. Entre as espécies preferencialmente caçadas e as primeiras a desaparecer pela fragmentação florestal, estão aquelas de grande porte e as frugívoras. A extinção destas espécies pode trazer consequências negativas para os ecossistemas, pois elas estão envolvidas em processos-chave na manutenção da diversidade florestal, como a dispersão de sementes. Este estudo buscou verificar, através de uma revisão bibliográfica, o efeito da defaunação sobre o recrutamento de plântulas, observando se a ausência dos dispersores de sementes realmente interfere na diversidade e regeneração florística das florestas. Em geral, a defaunação apresenta efeitos negativos sobre a regeneração e diversidade florestal, ainda que as evidências disponíveis indiquem que não há um padrão definido.
