Resumo: | During the period of April 1983 to September 1984 a fauna survey in bracatinga (Mimosa scabrella, Benth.) was conducted in Almirante Tamandaré, PR. Samples were taken at 15 days time intervals in canopies of groves with 8, 42 and 60 months old using a canopy net, and the respective ground vegetation with a sweep net. To obtain the diversity index the formula alfa = (S-1)/log N was used. To tabulate the data, the option was taken for the orders Homoptera, Hemiptera and Coleoptera, since they had greater quali-quantitative consistency. According to the data it became evident that as tree age increases there is a simultaneous increase in species diversity. In regard to the two ecosystems studied the ground vegetation showed a greater diversity index as well as in regard to species diversity among families. Chrysomelidae present the higher index in the ecosystem formed by canopies and among different ground vegetation the most evident was the Curculionidae family. |

In regard to the two ecosystems studied the ground vegetation showed a greater diversity index as well as in regard to species diversity among families. Chrysomelidae present the higher index in the ecosystem formed by canopies and among different ground vegetation the most evident was the Curculionidae family. No período de abril de 1983 a setembro de 1984, efetuou-se o levantamento da entomofauna da bracatinga, em Almirante Tamandaré, PR. Os levantamentos foram efetuados quinzenalmente em copas de talhões com 8, 42 e 60 meses de idade, através da rede de copa e, de seus respectivos sub-bosques com rede de varredura. Para o cálculo do índice de diversidade utilizou-se a fórmula alfa = (S-1)/log N. Para a tabulação dos dados, optou-se pelas ordens Homoptera, Hemíptera e Coleóptera que apresentaram maior consistência quali-quantitativa. De acordo com os resultados obtidos ficou evidenciado que com o aumento da idade da planta e de seu respectivo sub-bosque ocorre um aumento concomitante e gradativo da diversidade das espécies. Com relação aos dois ecossistemas estudados o sub-bosque apresentou um valor maior para o índice de diversidade e no que se refere a diversidade das espécies entre famílias, separadamente, Chrysomelidae destacou-se com o mais alto índice para o ecossistema formado pelas copas e, entre os diferentes sub-bosques destacou-se a família Curculionidae.Universidade Federal de Santa Maria1999-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/28510.5902/19805098285Ciência Florestal; Vol. 3 No. 1 (1993); 65-76Ciência Florestal; v. 3 n. 1 (1993); 65-761980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/285/pdfCosta, Ervandil CorrêaLink, DionisioMedina, Liliana D. deinfo:eu-repo/semantics/openAccess2017-08-29T20:55:36Zoai:ojs.pkp.sfu.ca:article/285Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-08-29T20:55:36Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
