Pesquisa do Estado de Minas Gerais (FAPEMIG) / Foram utilizadas esp?cies de Coleoptera Scarabaeidae como bioindicadores para avaliar a efetividade de faixas de vegeta??o em recomposi??o como corredores ecol?gicos entremeados a plantios comerciais de eucalipto. O estudo foi desenvolvido em cinco munic?pios do Alto Vale do Jequitinhonha, Minas Gerais. Comparou-se a estimativa da diversidade de esp?cies, relacionando os diferentes tipos de isca utilizados e os ecossistemas. A amostragem foi realizada em seis tipologias: regenera??o inicial e avan?ada, com presen?a e aus?ncia de remanescentes de Eucalyptus spp, o Cerrado e o plantio comercial. Utilizou-se armadilhas pitfall, iscadas com fezes humanas, fezes bovinas, ba?o bovino apodrecido e banana apodrecida. Estimadores de diversidade, de compartilhamento de esp?cies e de similaridade foram utilizados para aferir a diversidade alfa e beta das ?reas estudadas. Foram realizadas an?lises de correspond?ncia e An?lise de Esp?cies Indicadoras. A presen?a de remanescentes de Eucalyptus spp. parece interferir nos resultados de riqueza, diversidade local e regional dos besouros. O atrativo composto por fezes humanas apresentou maior efici?ncia, atraindo maior quantidade de indiv?duos, al?m da maior riqueza de esp?cies na maioria das fitofisionomias estudadas. Do total de esp?cies analisadas como indicadoras menos de 25% apresentaram prefer?ncia por alguma das quatro iscas e/ou por alguma das seis fitofisionomias. A heterogeneidade dos habitat afetou a riqueza e influenciou a estrutura e composi??o de esp?cies da assembleia de besouros escarabe?deos nas faixas ecol?gicas entremeadas a eucaliptocultura. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Ci?ncia Florestal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2015. / To evaluate the effectiveness of native vegetation ranges on recovery as ecological corridors intermingled between eucalypt plantation, species of Scarabaeidae were used as bio-indicators. The study was conducted in five districts of Alto Jequitinhonha Valley, Minas Gerais. A comparisson of the estimated diversity of species of the Scarabaeidae was made, relating different types of bait used and phytophysiognomies found in the area. Sampling was carried out in six sampling sites, including sites in early and advanced regeneration, with and without remnants of Eucalyptus ssp., the Cerrado and the commercial planting. We used pitfall traps, baited with human feces, bovine feces, the attraction consists of human feces proved to be the most efficient, attracting greater number of individuals and species and rotten banana. Diversity, species sharing and similarity estimators were obtained to measure alpha and beta diversity of the studied areas. The presence of remnants of Eucalyptus spp. wealth appears to interfere in results, diversity and local regional beetles. Increased number of individuals, beyond the higher species richness in most of the studied vegetation types. Among the total sampled species and analyzed as indicator species, less than 25% had presented preference for any of the four baits and any of the six phytophysiognomies. The heterogeneity of habitat had affected the richness and had influenced the estructure and composition of species of the assembly of escarabaeideos beetles at the ecological zones intermingled eucalyptus plantations.
