Resumo: http://dx.doi.org/10.5902/1980509816603The aim of this study was to analyze the degradation state of forest fragments applying seed rain as an indicator. Fragments (n = 5) in semideciduous forest, in Sorocaba, SP state, were studied from August to October, in 2007, and from January to December, in 2008, and seed traps were established in 11 plots (10 x 10 m). The material was separated and seeds and fruits were identified and classified based on dispersion syndrome and habit. Although fragments F4 and F5 showed high richness, diversity and equitability, there were dominance of herbaceous and anemochoric species. The highest proportion of seed rain was observed in F1, F2 and F4, with 36.8%, 26.8% and 17.8%, and F3 and F5, showed only 12.6% and 5.9%. The seed rain was seasonal and higher in the transition from dry to wet season, with 63% of total seed rain. The anemochory was the most representative syndrome (86%), that is more observed in open and degraded areas. The results indicated viability of the quantitative analysis of seed rain for monitoring the fragment restoration, being effective to detect environmental differences among fragments.

Fragmentos (n= 5) de Floresta Estacional Semidecidual na região de Sorocaba - SP foram estudados de agosto a outubro de 2007 e janeiro a dezembro de 2008, utilizando-se coletores instalados em 11 parcelas (10 x 10 m). Do material coletado foram separadas as frações de sementes e frutos para identificação e classificação por síndrome de dispersão e hábito. Os resultados demonstraram que, embora os fragmentos F4 e F5 apresentem os maiores índices de riqueza, diversidade e equitabilidade, há a dominância de espécies anemocóricas e herbáceas. Os fragmentos F1, F2 e F4 foram os com maior aporte de sementes, respectivamente com 36,8%, 26,8% e 17,8% e os fragmentos F3 e F5, apenas 12,6% e 5,9%. O aporte de propágulos foi sazonal sendo maior na transição da estação seca para a úmida, o que resulta em 63% do total de propágulos aportados. A síndrome com maior representatividade foi a anemocoria (86%), comum em áreas abertas e degradadas. Os resultados obtidos indicam a viabilidade da aplicação do estudo quantitativo da chuva de sementes para o monitoramento da restauração de fragmentos, tendo sido eficiente em detectar diferenças ambientais entre os fragmentos. Universidade Federal de Santa Maria2014-12-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1660310.5902/1980509816603Ciência Florestal; Vol. 24 No. 4 (2014); 911-923Ciência Florestal; v. 24 n. 4 (2014); 911-9231980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/16603/pdfPiña-Rodrigues, Fatima Conceição MárquezAoki, Julianainfo:eu-repo/semantics/openAccess2017-04-12T13:21:39Zoai:ojs.pkp.sfu.ca:article/16603Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-12T13:21:39Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
