Resumo: | The largest fragment of Figueira Farm (Londrina-PR state) with an area of 266 ha, is a Private Natural Heritage Reserve, and one of the most important remnants of the region. The aim of this study was to characterize the structure and tree diversity of this fragment, and evaluate the floristic relationship with other fragments of semideciduous forest studied in the state of Paraná. One hundred plots of 10 x 10 m were allocated and the arboreal individuals with 15 cm or more in circumference at breast height were sampled, resulting in 1,569 individuals, 32 families, 66 genera and 93 species. Families with greater number of species were Fabaceae (16 species), Meliaceae (nine species) and Myrtaceae (nine species). Trichilia clausseni C.DC. was the species with the highest importance in the study, reflecting higher values of density and relative frequency in the fragment. The largest relative dominance was presented by Gallesia integrifolia(Spreng.) Harms, by presenting large individuals with the highest values of basal area. The Shannon diversity index was found to be 3.37 nats/ind, a value considered significant and similar to other surveys in the region, and the index of evenness by Pielou was 0.743, indicating balance in the number of individuals among species. The presence of singletons and rare tree species in Paraná as well as the total diversity of species and the degree of conservation of the fragment, demonstrate the importance of the preservation and management of the remnant. Geographical proximity associated with similar environment factors as well as the predominant type of phytogeographic unit, showed closer floristic relationships, on the other hand, local environmental factors such as proximity to watercourses differentiated its flora of nearby places. |

O maior fragmento da Fazenda Figueira (Londrina-PR) com área de 266 ha, é uma Reserva Particular de Patrimônio Natural, e um dos mais importantes remanescentes da região. O objetivo deste trabalho foi caracterizar a estrutura e a diversidade arbórea do referido fragmento, e avaliar a relação florística com outros fragmentos de Floresta Estacional Semidecidual estudados no estado do Paraná. Foram alocadas 100 parcelas de 10 x 10 m, e em cada uma delas foram amostrados os indivíduos arbóreos com 15 cm ou mais de Circunferência a Altura do Peito, resultando em 1569 indivíduos, distribuídos em 32 famílias, 66 gêneros e 93 espécies. As famílias que mais se destacaram em número de espécies foram Fabaceae (16 espécies), Meliaceae (nove espécies) e Myrtaceae (nove espécies). Trichilia clausseni C.DC. foi a espécie de maior valor de importância no fragmento estudado, reflexo dos maiores valores de densidade e frequência relativa. A maior dominância relativa foi apresentada por Gallesia integrifolia (Spreng.) Harms, por apresentar indivíduos de grande porte com os maiores valores de área basal. O índice de diversidade de Shannon encontrado foi de 3,37 nats/ind, valor este considerado expressivo e similar a outros levantamentos na região, e o índice de equabilidade de Pielou foi de 0,743 indicando equilíbrio no número de indivíduos entre as espécies. A presença de espécies com apenas um indivíduo amostrado e de espécies consideradas raras no Paraná, bem como a diversidade total das espécies e o grau de conservação do fragmento, demonstram a importância da preservação e manejo do remanescente. A proximidade geográfica associada a fatores ambientais semelhantes, assim como ao tipo de unidade fitogeográfica predominante, evidenciaram relações florísticas mais próximas, por outro lado, fatores ambientais locais como proximidade a cursos d’água diferenciaram a flora de locais próximos.Universidade Federal de Santa Maria2016-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2419510.5902/1980509824195Ciência Florestal; Vol. 26 No. 3 (2016); 713-725Ciência Florestal; v. 26 n. 3 (2016); 713-7251980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/24195/14149Copyright (c) 2016 Ciência Florestalinfo:eu-repo/semantics/openAccessEstevan, Daniela AparecidaVieira, Ana Odete SantosGorenstein, Maurício Romero2017-04-06T11:04:34Zoai:ojs.pkp.sfu.ca:article/24195Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-06T11:04:34Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
