Resumo: Species invasion in natural communities is considered a greatthreat to global biodiversity. The second biggest cause of extinction worldwide is related to invasive species action, which is only smaller than habitat loss and fragmentation. The objective of this study was to quantify the levels of Pinus elliottii Engelm. var. elliottii infestation in Parque Florestal do Rio Vermelho, Florianópolis, SC, Brazil. One year after the clearance of one hectare of Pinus, 100 plots were set to evaluate Pinus regeneration. Semestral evaluations were made between the winter of 2003 and the summer of 2005. Population density showed significant differences (p<0.05), varying from 19,617 plants/ha to 166,624 plants/ha. The border effect became strong after the winter of 2004 and the emergence rate increased significantly. The zones closest to the border showed the highest population densities, reaching 362,268 plants/ha on the first 10m from the border. Themean population density of each zone resulted in a decreasing exponential equation where there were 569,598 plants/ha on the zone closest to the border and 43,768 plants/ha on the border's furthest zone. This led to the recommendation to cut all Young 2 plants about every 4 years in order to control the reinfestation.

A segunda maior causa de extinção de espécies no mundo está relacionada com a ação de espécies invasoras, superada apenas pela perda e fragmentação de habitats. O objetivo deste estudo foi quantificar os níveis de re-infestação de Pinus elliottii Engelm var. elliottii no Parque Florestal do Rio Vermelho, Florianópolis, SC. Um ano após a derrubada de um hectare de Pinus, foram montadas 100 parcelas para avaliar a regeneração de Pinus. Avaliações semestrais foram feitas do inverno de 2003 ao verão de 2005. A densidade populacional apresentou diferenças estatísticas, variando de 19.617 indivíduos/ha até 166.624 indivíduos/ha. O efeito de borda evidenciou-se a partir do inverno de 2004 e aumentou significativamente a taxa de emergência. As faixas mais próximas da borda apresentaram maiores densidades populacionais, chegando a 362.268 indivíduos/ ha até 10m da borda. A média da densidade populacional para cada faixa apresentou uma escala exponencial decrescente que vai de 569.598 indivíduos/ha na faixa mais próxima à borda a 43.768 indivíduos/ha na faixamais distante da borda. Sugere-se cortar os indivíduos em estágio Jovem 2 a cada 4 anos, aproximadamente, de forma a controlar a reinfestação.Universidade Federal de Santa Catarina2010-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2010v23n2p2310.5007/2175-7925.2010v23n2p23Biotemas; v. 23 n. 2 (2010); 23-302175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2010v23n2p23/15101Copyright (c) 2011 Kurt Bourscheid, Ademir Reisinfo:eu-repo/semantics/openAccessBourscheid, KurtReis, Ademir2018-03-02T14:23:53Zoai:periodicos.ufsc.br:article/16541Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2018-03-02T14:23:53Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
