Resumo: Seed rain participates in species enrichment during the natural regeneration of terrestrial ecosystems, as this ecological process promotes gene flow and the maintenance of forest biodiversity. However, few studies assessed variations in seed rain related to environmental heterogeneity inside forests. We studied the influence of relief (flat or slope areas) on the seasonal and monthly variation in density, floristic composition, and richness of the seed rain in an urban fragment of Atlantic Forest. We carried out the present study in Rain Tropical Forest, Northeastern Brazil. We selected two areas within the fragment: one with flat relief and the other on a slope. In each relief type we set up 20 0.25-m2 seed collectors, in a total of 40 units, to quantify seed rain. After ten months of study, we counted 9,474 seeds: 8,061 in the flat area and 1,413 in the slope area. There were significant differences in dispersal syndromes and plants habit between relief types. The seed density in the flat area differed between seasons and the species richness varied seasonally in both areas. There were variations in floristic composition between seasons in the flat and slope areas. Seed density was higher in December and January in the flat area. Differences in seed rain suggest that it is influenced by spatial heterogeneity and climate seasonality, and that the areas with different kinds of relief are important for the biodiversity conservation.

Estudiamos la influencia del relieve (áreas planas o en pendiente) sobre la variación estacional y mensual de la densidad, composición florística y riqueza de la lluvia de semillas en un fragmento urbano de Mata Atlántica. Realizamos el presente estudio en Bosque Tropical Lluvioso, en Noreste de Brasil. Seleccionamos dos áreas dentro del fragmento: una con relieve plano y la otra en pendiente. En cada tipo de relieve instalamos 20 recolectores de semillas de 0,25 m2, en un total de 40 unidades, para cuantificar la lluvia de semillas. Luego de diez meses de estudio, contamos 9.474 semillas: 8.061 en el área plana y 1.413 en el área pendiente. Hubo diferencias significativas en los síndromes de dispersión y las hábito de la planta entre los tipos de relieve. La densidad de semillas en el área plana difiere entre las estaciones y que la riqueza de especies varía estacionalmente en ambas áreas. Hubo variaciones en la composición florística entre estaciones en las áreas planas y en pendiente. La densidad de semillas fue mayor en diciembre y enero en la zona llana. Las diferencias en la lluvia de semillas sugieren que está influenciada por la heterogeneidad espacial y la estacionalidad climática, y que las áreas con diferentes tipos de relieve son importantes para la conservación de la biodiversidad.A chuva de sementes participa do enriquecimento de espécies durante a regeneração natural dos ecossistemas terrestres, pois esse processo ecológico promove o fluxo gênico e a manutenção da biodiversidade florestal. No entanto, poucos estudos avaliaram as variações na chuva de sementes relacionadas à heterogeneidade ambiental no interior das florestas. Estudamos a influência do relevo (áreas planas ou de encosta) na variação sazonal e mensal da densidade, composição florística e riqueza da chuva de sementes em um fragmento urbano de Mata Atlântica. Realizamos o presente estudo em uma Floresta Tropical Úmida, no Nordeste do Brasil. Selecionamos duas áreas dentro do fragmento: uma com relevo plano e, sendo a outra, uma encosta. Em cada tipo de relevo foram instalados 20 coletores de sementes de 0,25 m2, num total de 40 unidades, para quantificar a chuva de sementes. Após dez meses de estudo, contabilizamos 9.474 sementes, das quais, 8.061 foram observadas na área de relevo plano e 1.413 na área de encosta. Houveram diferenças significativas nas síndromes de dispersão e hábito das plantas entre os tipos de relevo. A densidade de sementes na área plana diferiu entre as estações e a riqueza de espécies variou sazonalmente em ambas as áreas. Houve variações na composição florística entre as estações nas áreas plana e de encosta. A densidade de sementes foi maior nos meses de dezembro e Janeiro na área plana. Diferenças na chuva de sementes sugerem que ela é influenciada pela heterogeneidade espacial e sazonalidade climática, e que as áreas com diferentes tipos de relevo são importantes para a conservação da biodiversidade.Research, Society and Development2022-05-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2991210.33448/rsd-v11i7.29912Research, Society and Development; Vol. 11 No. 7; e29511729912Research, Society and Development; Vol. 11 Núm. 7; e29511729912Research, Society and Development; v. 11 n. 7; e295117299122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/29912/25880Copyright (c) 2022 Priscila Silva dos Santos; Kleber Andrade da Silva; Elcida de Lima Araújo; Elba Maria Nogueira Ferrazhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Priscila Silva dos Silva, Kleber Andrade da Araújo, Elcida de Lima Ferraz, Elba Maria Nogueira 2022-06-06T15:12:05Zoai:ojs.pkp.sfu.ca:article/29912Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:46:51.297611Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
