Resumo: | http://dx.doi.org/10.5902/1980509817442To test the hypothesis that the physiognomy, structure and dynamics of woody species are influenced by the spatial gradient edge-interior, data were collected from these parameters in 2004, 2007 and 2010 in an Atlantic forest fragment. Species were sampled for the Canopy (DS), with circumference > 15 cm to 1.3 m MARTÍNEZ-soil and understory (SB) in circumference between ground level> 3 cm and CAP <15 cm on edge-gradient formed within 35 years. In 2004, we assessed three positions in the fragment: edge, intermediate and inner (> 150 m from the forest boundary), and analyzed 1,000 m² per site, divided into plots of 10 m², to measure individuals of higher class. In each plot a sub-plot of 5 m² for sampling understory was installed. Branches were collected from three adult individuals from the species to obtain the density of the wood. The number of individuals (NI), basal area (BA), mortality (TM), recruitment rate (TR), periodic annual diameter increment (IPA), loss rate (P) and gain rate (G) Area and basal turnover rates in number of individuals (TN) and basal area (TA) class tree component in the three locations showed no significant edge effect. At the edge, the understory had lower values of NI and AB and higher TM than in the forest interior. Differences between the strata occur regardless of edge sealing, since young plants present in most individuals in the sample class SB, which are more sensitive than adult trees to changes caused by the creation of the edge. Rates of loss and gain of AB and AB turnover in NI and in SB presented higher values than on the DS, which points to a stratum with larger changes. In DS there were no differences in species richness among environments differs from that observed in SB. The floristic composition of the DS in environments closer to the forest limit was quite distinct from that of the interior, indicating that there has been no recovery of floristic composition. All environments SB had low similarity. The edges of the DS and SB had a higher concentration of individuals in class intervals smaller density values timber. The DS has already recovered biomass, although the edge and intermediate environments have not recovered species composition late. The SB still suffers the edge effect. Possibly, the highest concentration of individuals is in class with lower density wood result on edge. |

Foram amostradas para o Dossel (DS), plantas com circunferência docaule a altura do peito (CAP) > 15 cm e do sub-bosque (SB) com circunferência ao nível do solo entre >3 cm e CAP < 15 cm em um gradiente borda-interior formado há 35 anos. Em 2004, foram avaliadas trêsposições no fragmento: borda, intermediária e interior (> 150 m do limite florestal), sendo analisados 1000m² por local, divididos em parcelas de 10 m², para medir os indivíduos de maior classe. Em cada parcelafoi instalada uma subparcela de 5 m² para amostragem do sub-bosque. Foram recolhidos ramos de trêsindivíduos adultos das espécies, para obtenção da densidade da madeira. O número de indivíduos (NI), áreabasal (AB), taxa de mortalidade (TM), taxa de recrutamento (TR), incremento periódico anual em diâmetro(IPA), taxa de perda (P) e ganho (G) de área basal e as taxas de rotatividade em número de indivíduos (TN)e em área basal (TA) da classe do componente arbóreo nos três locais evidenciaram não haver efeito deborda significativo. Na borda, o sub-bosque teve menores valores de NI e AB e maiores TM, que no interiordo fragmento. Diferenças entre os estratos acontecem, independentemente do selamento da borda, já queplantas jovens na maior classe amostral apresentam indivíduos no SB, que são mais sensíveis que as árvoresadultas às mudanças causadas pela criação da borda. Taxas de perda e ganho de AB e de rotatividade em NI eAB, no SB, apresentaram valores maiores que no DS, o que aponta para um estrato com maiores mudanças.No DS não ocorreram diferenças de riqueza de espécies entre os ambientes, distinto do observado no SB.A composição florística no DS nos ambientes mais próximos ao limite florestal foi bastante distinta que ado interior, indicando que ainda não houve recuperação da composição florística. Todos os ambientes doSB tiveram baixa similaridade. As bordas do DS e SB apresentaram maior concentração de indivíduos emintervalos de classe de menores valores de densidade de madeira. O DS já recuperou a biomassa, embora osambientes de borda e intermediário não tenham recuperado a composição de espécies tardias. O SB aindasofre efeito de borda. Possivelmente, a maior concentração de indivíduos em classe de menor densidade damadeira sendo resultado na borda.Universidade Federal de Santa Maria2015-03-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1744210.5902/1980509817442Ciência Florestal; Vol. 25 No. 1 (2015); 23-36Ciência Florestal; v. 25 n. 1 (2015); 23-361980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/17442/pdfRabelo, Felipe Rodrigo de CarvalhoRodal, Maria Jesus NogueiraLins e Silva, Ana Carolina BorgesLima, André Luiz Alves deinfo:eu-repo/semantics/openAccess2017-04-11T14:11:19Zoai:ojs.pkp.sfu.ca:article/17442Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-11T14:11:19Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
