“…This study was carried out in a seasonal deciduous forest fragment located in the Peixe River Valley, municipalities of Piratuba and Ipira, Midwest of Santa Catarina State, Brazil (Figure 1). The fragment area has approximately 125 ha and is located between the geographical coordinates 27°25′34″ S and 51°47′18″ W. The study area belongs to the seasonal deciduous forest vegetation formation, which is formed by an emergent arboreal stratum represented by species of pantropical genera, including species adapted to leaf loss due to physiological drought caused by the winter cold during two months a year, with averages of temperature lower than 15 °C (IBGE, 2015, FREITAS et al, 2016a.…”

Forest structure studies may be carried out through the diametric distribution of individuals within a population, which is defined by characterizing the number of trees per unit area and diameter class intervals. The De Liocourt's q quotient can be used to assess the relationship between recruitment and mortality in forest communities because when a constant ratio occurs between the classes, it represents that the recruitment rate is similar to the mortality rate and the distribution can be considered as regular or balanced. This study aims to analyze the diametric structure of the arboreal component of a seasonal deciduous forest fragment located in the Peixe River Valley, Midwest of Santa Catarina State, Brazil. The sampled individuals were distributed in diameter classes with an amplitude of 5 cm, in which the center of the first class presented a value of 6.5 cm. Subsequently, the observed and estimated diametric distribution curves were constructed for the overall sampling and for species with the highest importance value (IV) and with different ecological attributes. The study area presented a deficit of trees in the overall and per species diameter classes when compared to a balanced forest. The De Liocourt's q quotient can be used to assess the diametric structure of deciduous forest fragments.

“…In this region, the humid mesothermal climate (Cfa) is predominant, with no distinct dry season, with monthly precipitations above 60 mm, average temperatures of the warmest months above 22 °C and of the coldest month below 18 °C and above 3 °C (FREITAS et al, 2016a).…”

“…A quantidade de estratos é característica de cada floresta pela sua composição de espécies, relações competitivas, restrições ambientais e perturbações antrópicas ou naturais (Souza & Souza, 2004). A análise da estrutura florestal em conjunto com a regeneração natural é importante para o desenvolvimento de planos de restauração, conservação e manejo dos fragmentos florestais, assegurando os atributos da comunidade (Freitas & Magalhães, 2016).…”

Este estudo teve como objetivo avaliar se um talhão de Eucalipto sem manejo a 20 anos está em processo de restauração. O levantamento foi realizado na Reserva Particular de Patrimônio Natural – RPPN – Botujuru, em Mogi das Cruzes, SP. Foram instalados seis transectos de 100m, com quatro parcelas circulares de 50m² (3,99m de raio) e quatro retangulares de 1mx10m. Os dados foram categorizados em estrato regenerante (até 1,3m), estrato 2 (perímetro a altura do peito (PAP) ≤ 15cm) e estrato 3 (PAP > 15cm). Nos resultados verificou-se a diferença na composição dos estratos. Enquanto as pioneiras apresentaram alto valor de importância nos estratos superiores, no estrato regenerante as famílias e espécies recrutadas são principalmente as não pioneiras. Indivíduos da espécie Eucalyptus foram encontrados apenas no estrato três, mostrando que na aérea de estudo ele não atua como espécie invasora. Conclui-se que pela diversidade encontrada no sub-bosque, a substituição das espécies nos estratos e a abundância de espécies não pioneiras, está ocorrendo o processo de restauração.

“…A estrutura florestal está fundamentalmente ligada a processos funcionais que controlam o provisionamento de serviços ecossistêmicos em paisagens florestais (THOM ; KEETON, 2019). Nesse contexto, a análise da estrutura vertical em florestas pode evidenciar, dependendo, da região fitoecológica, estádio de sucessão e estado de conservação, a presença de sub-bosque, como o estrato inferior, estrato médio e estrato superior, ou não apresentar estratificação evidente (ARAÚJO et al, 2016;GUIMARÃES et al, 2016;MAGALHÃES, 2016;MIGUEL et al, 2016). Além disso, o conhecimento dos estratos presentes em áreas de florestas nativas fornece informações que podem auxiliar diretamente no plano de colheita de frutos e sementes florestais.…”

The study of the vertical stratification of the forest evidences the dominance of certain species in relation to the ecological behavior. Additionally, it can also support in the definition of climbing methods for harvesting fruits and seeds in the tree canopy. The present work aimed to analyze the vertical structure based on the individuals that compose the different botanical families in the Seed Collection Area (SCA) belong Parakanã Indigenous Land (PIL), Pará state. The height of 10,383 individuals present at ACS of T.I. Parakanã was determined by the visual estimation method. Subsequently, five height classes (superior class 1, superior 2, middle 1, middle 2 and inferior) were defined for the individuals' distribution. By the multivariate analysis the families were grouped by similarity equal to 70%. The results showed that the families Anacardiaceae, Fabaceae, Lauraceae, Lecythidaceae and Moraceae belong to the SCA canopy. The different botanical families formed six groups considering similarity equal to 70%. Group 1 and 2, with 29 families, constitute the superior stratum of the forest, however, also have individuals in the inferior classes; groups 3 and 4, with 14 families, constitute the intermediate canopy and sub-forest; group 5, equivalent to 7 families, is located 100% in the intermediate canopy, and, in relation to group 6, formed only by 2 families, the individuals are in the total sub-forest. The different strata observed in the SCA of PIL evidences the need to use different climbing methods to harvest fruits and seeds.
