Seasonal Semideciduous Forest

Considering the seasonal variation of fruits availability in seasonal semideciduous forests, this study analyzed whether the richness of fruit species exploited by Alouatta clamitans is higher in the rainy period rather than the dry one. Plant species consumed were investigated by visualization and feces analysis, from July 2005 to June 2006, in a seasonal semideciduous forest fragment in Paraná state, Brazil. Ten species of fruits were consumed during the rainy period and 13 during the dry period: three were consumed exclusively during the rainy period; six exclusively during the dry period; and seven in months that covered both dry and rainy periods. The number of fruit species consumed during the rainy period was considerably lower than the expected richness. Moreover, among fruit species consumed during the rainy period, only four bear fruits mainly in this period of the year, the other species bear fruits in great part of it. Therefore, the selectivity of A. clamitans was mainly directed to species capable of providing fruits along the year, prioritizing these species even when other fruit sources are available.

O objetivo deste estudo foi avaliar a estrutura e a composição florística da regeneração natural de trechos de Floresta Estacional Semidecidual em diferentes estágios sucessionais. Para a estrutura fitossociológica, foram demarcadas sistematicamente 10 parcelas de 5 x 10 m em trecho de floresta em estágio médio de regeneração (FEM), floresta em estágio avançado de regeneração (FEA) e pastagem abandonada (PAS), sendo amostrados os indivíduos com altura ≥ 50 cme diâmetro à altura do solo ≤ 5 cm. Foi realizada análise de correspondência retificada e análise de espécies indicadoras de cada trecho. Na estrutura da regeneração natural da FEM e da pastagem, houve destaque de apenas uma espécie (Psychotria sessilis e Vernonia polyanthes, respectivamente) quanto ao Valor de Importância (VI), devido principalmente à alta densidade. Já na FEA não foi observada forte dominância por uma espécie. As três áreas apresentaram-se distintas quanto à abundância e composição de espécies, sugerindo que a matriz florestal é composta por um mosaico sucessional. Além disso, cada trecho ainda mantém espécies indicadoras características, de acordo com o estágio sucessional em que se encontram, razão pela qual ações de manejo e enriquecimento poderiam ser adotadas para acelerar o processo de sucessão.Palavras-chave: Composição florística; conservação; estrutura; sucessão secundária. AbstractNatural regeneration of seasonal semideciduous forest in different successional stages (Zona da Mata, MG, Brazil). The objective of this study was to evaluate the floristic structure and composition of the natural regeneration of stretches from Seasonal Semideciduous Forest in different successional stages. Ten plots, 5 x 10 meters in size, were systematically delimited for phytosociological structure in patches of forest which were in intermediate regeneration stage (FEM), advanced regeneration stage (FEA) and abandoned pasture (PAS).We sampled the individuals with ≥ 50 cm in height and diameter at ground height ≤ 5 cm. We performed Detrended Correspondence Analysis and analysis of indicative species of each forest section. In the natural regeneration structure of FEM and pasture it was featured only one species (Psychotria sessilis and Vernonia polyanthes, respectively) in the Importance Value (IV), mainly due to high density. In relation to the FEA there was no strong dominance by one species. The three sections showed distinct species abundance and composition, which suggests that the forest matrix comprises a successional mosaic. Furthermore, each stretch still maintains indicative characteristic species, according to the successional stage they are in. Because of this, management and enrichment actions could be performed to accelerate the succession process.Keywords: Floristic composition; conservation; structure; secondary succession.

We examined floristic patterns of ten seasonal semideciduous forest sites in southeastern Brazil and conducted a central sampling of one hectare for each site, where we took samples and identified all individual living trees with DBH (diameter at breast height, 1.30 m) ≥4.8 cm. Arboreal flora totaled 242 species, 163 genera, and 58 families. Fabaceae (38 species) and Myrtaceae (20 species) were families with the largest number of species. OnlyCopaifera langsdorffiiandHymenaea courbariloccurred at all sites. Multivariate analysis (detrended correspondence analysis and cluster analysis) using two-way indicator species analysis (TWINSPAN) indicated the formation of a group containing seven fragments in whichSiparuna guianensiswas the indicator species. This analysis revealed that similarities between studied fragments were due mainly to the successional stage of the community.

In this study, the floristic composition of the interface of the seasonal semideciduous forest inserted in a pasture matrix was evaluated. Three transects of 10 m wide by 50 m long from the edge to the center of the fragment were installed systematically. Few species were responsible for more than half of the individuals, contributing to the low species richness detected. Bauhinia forficata and Urera baccifera have represented almost 40% of the individuals sampled. Besides this, a high density of pioneer species and abundance of few species up to 50 m were verified, confirming that the edge effect extends itself beyond the sampled distance. Future studies must perform samplings in bigger transactions in order to verify the extent of the edge effect on plant community.

O objetivo desse estudo foi avaliar as mudanças na composição florística em um fragmento de Floresta Estacional Semidecidual. No primeiro inventário realizado em 2011 foram alocadas 25 parcelas de 10 ×40 m. Foram mensurados todos os indivíduos vivos com diâmetro a altura do peito ≥ 5cm. O segundo inventário foi realizado em 2015, utilizando-se os mesmos critérios do inventário anterior, assim, foram incorporados os novos indivíduos (recrutas) que atingiram o diâmetro mínimo de inclusão. O correram mudanças na composição florística, a mortalidade dos indivíduos foi superior ao recrutamento, houve perda de cinco espécies e incremento de duas espécies. O número de espécies e a densidade dos indivíduos variaram com o tempo. As espécies que desapareceram eram representadas por poucos indivíduos. A perda de espécies refletiu no índice de diversidade de Shannon (H’) e equabilidade de Pielou, (H’passou de 4,05 para 3,99 e equabilidade de Pielou J’ de 0,83 para 0,82), no primeiro e segundo inventário respectivamente, mesmo assim, os valores apontam para uma diversidade florística elevada. As mudanças na composição florística não foram significativas, a perda de espécies teve relação com as menos representativas em número de indivíduos, entre os inventários a floresta se manteve estável.Palavras-chave: mortalidade, recrutamento, sucessão ecológica. VARIATIONS IN THE FLORISTIC COMPOSITION IN SEASONAL SEMIDECIDAL FORESTS IN CURVELO-MG ABSTRACT: The objective of this study was to evaluate the changes in floristic composition in a fragment of Seasonal Semideciduous Forest. In the first inventory carried out in 2011, 25 plots of 10 × 40m were allocated. All living individuals with a breast height diameter ≥5 cmwere measured. The second inventory was carried out in 2015, using the same criteria of the previous inventory, thus, were incorporated the new individuals (recruits) that reached the minimum diameter of inclusion. The floristic composition changes, the mortality of the individuals was superior to the recruitment, there were loss of five species and increase of two species. The number of species and the density of individuals varied over time. The species that disappeared were represented by few individuals. The loss of species reflected in the diversity index of Shannon (H ') and Pielou equability, (H' went from 4.05 to 3.99 and Pielou J 'equability from 0.83 to 0.82), in the first and second inventory respectively, even so, the values point to a high floristic diversity. The changes in floristic composition were not significant, the loss of species was related to the less representative in number of individuals, among the inventories the forest remained stable.Keywords: mortality, recruitment, ecological succession.

Bat assemblages in two urban fragments of Maringá city, north of the state of Paraná, southern Brazil, were inventoried. These fragments, Parque do Ingá (48 ha) and Parque Florestal dos Pioneiros (59 ha), are located in a subtropical region covered by semideciduous Atlantic forest. Bats were sampled with mist-nets from August 2006 to July 2007, over 24 nights (12 hours a night), adding up to a total of 30,240 h.m2 of net effort. A total of 839 individuals were captured belonging to 10 species and four families. Artibeus lituratus was the most abundant species (66% of the sample). The observed richness represents 22% of the bat species recorded for the state, 24% of the bat species occurring in the seasonal semideciduous forest of Paraná, 26% of the species previously recorded in urban environments in Brazil, and 83.4% of the estimated richness by Jackknife 1 (n= 12 species). Studies that provide data on richness and abundance of bat species in urban fragments are becoming increasingly important, but are still poorly available in Brazil. This habitat is especially interesting because anthropogenic pressure can be harmful to bat assemblages, reducing their diversity.

Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry seasons, where climatic variables are regarded to be good predictors of populational patterns. The main goal of this paper is to investigate the seasonality of males of orchid bees in fragments of Seasonal Semideciduous Forest in southern Brazil. Data comprise bait samples from five one-year periods on four forest fragments. The seasonality of species abundance was tested with circular statistics. Results suggest two phenological patterns, one for Eufriesea violacea (Blanchard), Eulaema nigrita Lepeletier and Euglossa cordata (Linnaeus), whose abundances are concentrated in late spring and early-middle summer and another for Euglossa fimbriata Moure with a tendency to be collected in middle-late summer and early autumn. These patterns are discussed, as well the possible driven factors, (i) the species life cycle and nesting behavior, (ii) synchrony with resource, and (iii) climate. We can postulate an important impact of climate change in local euglossine assemblage due to the small populations and marked seasonality.

 In this study, we evaluated the floristic composition of vascular epiphytes in seasonal semideciduous forest fragments of the Itapemirim River basin, Southern State of Espírito Santo, in order to verify its similarity to other semideciduous forests studied in Brazil. Excursions were conducted every fortnight between June 2008 and May 2009, and epiphytes were collected and recorded (55 species, 34 genera and six families). Orchidaceae (21 species) was the richest family, whereas the genera presenting the greatest richness were Tillandsia (seven), Rhipsalis (four), Aechmea, Epidendrum and Peperomia (three species each). The category the most representative was characteristics holoepiphytes (84%). The riparian forests were the most important environments for the epiphytic flora. Similarity analysis and PCA supported four groups, where the study area appears disjointed from the others, supporting the hypothesis that geographical proximity, elevation and climate have a strong effect on the floristic composition, conditioning the formation of distinct floras. Detailed surveys on the floristic composition and structure of this community are important for the elaboration of studies on coherent environmental impacts, since epiphytes are typical in tropical rainforests, and they are an important floristic, structural and functional component of these ecosystems.
