Resumo: The present study had as objective to analyze the spatial pattern of the anemocoric and zoocoric species in environments with different individuals densities. The study was conducted in two fragments of Highland Araucaria Forest: one under silvipastoril system and another in a forest under secondary succession, in the municipality of Turvo, Paraná State, Brazil. The coordinates (x, y) of each point was registered. The spatial pattern was analyzed through the function K of Ripley, in the univariate form, using the package Splancs. In the area under silvipastoril system, anemochory syndrome is aggregated, while individuals with zoochory dispersion syndrome showed aggregated pattern up to 15 m and random pattern in the upper classes. Anemocoric species showed aggregated pattern in the area under secondary succession regardless the distance. Probably, more complex factors, such as dispersers’ ecology, interspecific relationships and environmental features may define the spatial distribution of some species.

O estudo foi realizado em dois fragmentos de Floresta Ombrófila Mista Alto-Montana: um sob sistema silvipastoril e outro em uma floresta em processo de sucessão secundária, no município de Turvo, PR. Foram registradas as coordenadas (x, y) de cada ponto, sendo o padrão espacial analisado com a aplicação da função K de Ripley, na forma univariada, utilizando-se o pacote Splancs. Na área sob sistema silvipastoril, as espécies anemocóricas apresentam-se de forma agregada, enquanto que as espécies com síndrome de dispersão zoocórica apresentam padrão agregado até 15 m e aleatório nas classes superiores. Na área em sucessão secundária, as espécies anemocóricas estão agregadas em todas as classes de distância. Possivelmente, fatores mais complexos, como a ecologia dos dispersores, relações interespecíficas e características ambientais, podem definir a distribuição espacial de algumas espécies.Embrapa Florestas2019-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/170010.4336/2019.pfb.39e201801700Pesquisa Florestal Brasileira; v. 39 (2019)Pesquisa Florestal Brasileira; Vol. 39 (2019)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1700/895https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessSilva, Richeliel AlbertMazon, Joelmir AugustinhoWatzlawick, Luciano Farinha2019-12-31T20:35:27Zoai:pfb.cnpf.embrapa.br/pfb:article/1700Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2019-12-31T20:35:27Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
