Caracterização da vegetação secundária do bioma mata atlântica com base em sua posição na paisagem

This study characterized the Atlantic Forest vegetation and compared the structure of the native tree community occurring along a toposequence at watershed D of the Serra do Mar State Park, municipality of Cunha, SP - Brazil. The study was conducted in 64 plots, of 10 x 10 m, distributed in sites downstream (T1), intermediate (T2) and upstream (T3) of the toposequence, recording all individuals with DBH (Diameter at Breast Height) >= 0.5 cm. Altogether 1.093 individuals were sampled, and 89 species were identified, belonging to 61 genders and 31 families. At T1 site there was a greater abundance and density of individuals; T2 had the highest diversity index and basal area; while in T3 it was observed highest species richness and greater percentage of rare species. The specie Cyathea delgadii in the lower third of toposequence, and the Alchornea triplinervea in the intermediate and upper third were the most important. The sites downstream and upstream of the toposequence showed the largest differences in structure. In the middle portion of the watershed and there was a greater difference between the similarity between species.

Avaliação da influência do enriquecimento ambiental nas variáveis comportamentais de saguis-de-cara-branca (Callithrix geoffroyi) em cativeiro

Six species of the genus Callithrix can be found across the Atlantic Forest extension, being the Callithrix geoffroyi, Geoffroy`s marmoset, the least studied species. The objective of this study is to investigate the behavioral aspects of the species in captivity, and how the environmental enrichment techniques influence those behaviors. To this end, we have studied three specimens of C. geoffroyi, in captivity at Municipal Zoo of Piracicaba, São Paulo. The enclosure includes a 37m2 with under masonry, concrete platforms with external deep, trunks, a floor of grass and soil, e grid in their other three sides. The sampling method was focal per time interval, with records every 30 seconds in sessions of 30 minutes, totaling 30 hours for each animal, which were distributed in a baseline phase, an environmental enrichment phase and post-enrichment phase (n = 3660 records in each phase). The twelve enrichment techniques were applied: the physical environment (branches for perches and hoses fabrics for bedding and vanishing points), cognitive (radio, mirror, puzzle food) and food (insects, flowers and eggs hidden, wrapped). Initially, to determine the period of greatest activity of marmosets, we investigated the pattern of activity for three days (9:00 am to 17:00 pm) consecutively at intervals of 15 minutes, recording the number of active and inactive individuals. The 495 records signaled greater activity in the morning, then selected period for the completion of this work. The ethogram comprised 16 behaviors. The inactivity was the predominant phase behavior baseline and post-enrichment with a significant decrease (h=8,62, p <0.01) in the enrichment phase, and a significant increase in the post enrichment (h=18,15, p <0.001). The same was seen for the use of substrate (grid and ground vs. Trunk and concrete, h=5,09, p <0.001 and h=3,98, p <0.05)... (Complete abstract click electronic access below)

A influência de variáveis ambientais na distribuição e abundância de Brachycephalus ephippium na Serra do Japi, Jundiaí, São Paulo

The Atlantic forest has a large number of endemic species due to the varieties of environments, altitudes, and climates found along its distribution. The species Brachycephalus ephippium is an example of endemic anuran from this forest formation, occurring in the states of São Paulo, Rio de Janeiro and Minas Gerais, between 750 and 1200 m altitude. This species is abundant in the Serra do Japi, an Atlantic Forest remnant, which houses high biodiversity, located in Jundiaí city, between three big urban centers in the state of São Paulo. This remnant, which has altitude ranging between 700 and 1300 meters, is threatened by global climate changes and, spite of legally protected, by intense pressure of urbanization. The aim of the present study was to verify the association between of environmental variables with the abundance and distribution of B. ephippium in the Serra do Japi. The air relative humidity showed a positive correlation with the presence of B. ephippium individuals and the best model to explain the abundance involved air relative temperature and litter temperature. These results allowed the investigation of the environment use by this species and can be used to provide conservationist actions
