Estudo comparativo das comunidades de aranhas em diferentes fitofisionomias da Floresta Nacional - FLONA de Silvânia (Goiás, Brasil)

Abstract

As aranhas desempenham muitos papéis ecológicos importantes nos ecossistemas, sendo o controle de espécies um dos mais relevantes. No presente estudo, foi avaliada a composição da comunidade de aranhas de estratos arbustivos em uma área do cerrado, todas localizadas no interior da Floresta Nacional de Silvânia (FLONA). Foram adotadas áreas sob diferentes fitofisionomias, como Campo Sujo, Cerrado Stricto Sensu e Mata de Galeria. Foram coletados 282 indivíduos, classificados em 136 adultos e 146 juvenis, distribuídos em 23 famílias, 48 gêneros e 78 espécies. As espécies mais abundantes foram Sparassidae sp., Salticidae sp. e Tmarus sp.1. Embora a composição das espécies fosse diferente entre as três áreas, não houve diferenças significativas entre a riqueza de espécies nas áreas amostradas, e a riqueza amostral foi satisfatória, com uma representatividade alta. As espécies de aranhas foram classificadas em oito guildas tróficas, as aranhas Caçadoras de emboscada foram as mais abundantes, e houve maior concentração das guildas na mata de galeria, onde foram encontradas todas as guildas. Assim, o estudo indica que a riqueza e abundância possuem composições próprias, corroborando os estudos que indicam que as aranhas são um bom modelo para o estudo da hipótese de comunidades.
