Resumo: This research aimed to evaluate the influence of luminosity and distance from an igarapé on seedling density in an upland forest in the Central Amazon. Twenty plots were installed, where we measured the percentage of canopy openness, and the distance from an igarapé, and we also counted the number of seedlings. We obtained a linear regression of canopy openness with the seedling density and an ANOVA of seedling density according to the distance from an igarapé. We registered a total of 229 seedling individuals (seedling density = 11 plants/m2). Among the environmental variables measured, only canopy openness has positively influenced on seedling density. Small amplitude in the increase in luminosity can cause an increased seedling density. Seedling density did not differ with regard to the distance from an igarapé, due to low competitiveness and adaptations by species occurring in the wetlands.

Foram instaladas vinte parcelas, onde medimos a porcentagem de abertura de dossel e a distância do igarapé, além de contar o número de plântulas. Foi feita uma regressão linear da abertura de dossel com a densidade de plântulas e uma ANOVA da densidade de plântulas em função da distância do igarapé. Foi registrado um total de 229 indivíduos de plântulas (densidade de plântulas = 11 plantas/m2). Dentre as variáveis ambientais aferidas, somente abertura de dossel influenciou positivamente a densidade de plântulas. Uma pequena amplitude no aumento da luminosidade pode ocasionar um acréscimo na densidade de plântulas. A densidade de plântulas não diferiu em relação à distância do igarapé, devido à baixa competitividade e adaptações das espécies que ocorrem em áreas alagadas.Universidade Federal de Santa Catarina2014-05-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2014v27n3p19110.5007/2175-7925.2014v27n3p191Biotemas; v. 27 n. 3 (2014); 191-1952175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2014v27n3p191/27674Copyright (c) 2014 Randolpho Gonçalves Dias-Terceiro, Gabriela Marques Peixoto, Tainá Sherlakyann Alves Pessoa, Eudécio Carvalho Necoinfo:eu-repo/semantics/openAccessDias-Terceiro, Randolpho GonçalvesPeixoto, Gabriela MarquesPessoa, Tainá Sherlakyann AlvesNeco, Eudécio Carvalho2017-10-19T18:48:35Zoai:periodicos.ufsc.br:article/29063Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T18:48:35Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
