1. Environmental factors affect population structure of tree ferns in the Brazilian subtropical Atlantic Forest
ABSTRACT Tree ferns are important elements of tropical forests, mainly because they are common and provide microhabitats for epiphytic plants. Due to their ecological importance, the aim of this study was to evaluate population structure, distribution, and influence of environmental variables on tree ferns in the state of Santa Catarina, southern Brazil. All

2. Colonization-related functional traits of plants in a 50-hectare plot of secondary tropical forest
ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonizatio

3. Nutrition of tree species in tropical dry forest and rainforest environments
ABSTRACT Knowledge of the nutritional efficiency of species can help revegetation of forest areas, guiding the use of species that best adapt to environmental humidity, altitude and diversity. The objective of this study was to evaluate the nutrient utilization efficiency of N, P, K, Ca and Mg of dominant species in tropical dry forest and rainforest environ

4. EFFECTS OF SEASONAL AIR TEMPERATURES AND LIGHT ON LEAF TRAITS AT ATLANTIC MONTANE FOREST, BRAZILIAN SOUTHEAST
ABSTRACT Seasonal variation of temperature could place physiological constraints on the distribution and performance of tropical forest plants, associated with light and water availability. A simple way to assess the relationship between temperature and plant physiology is through the characterization of leaf traits. The main aim of this study was to evaluat

5. The variability of the subantarctic front and the Southern Hemisphere atmospheric jet
Abstract The latitudinal variations of the Subantarctic Front (SAF) and Southern Hemisphere atmospheric jet were investigated for the period of 1993-2016. Zonal wind velocity, sea surface height and temperature data were used to identify these features over the South Atlantic, South Pacific and Indian Oceans individually. During this period, the atmospheric

6. Aquatic vascular plants of South Brazil: checklist and a comparative floristic approach
ABSTRACT Aquatic ecosystems support species diversity, and knowledge of plant communities is essential for wetland conservation programs. This study provides a checklist of aquatic vascular plants of South Brazil and establishes their floristic affinities with bordering South America phytogeographical domains. The checklist was based on 52 sources, including

8. Salinity and stable oxygen isotope relationship in the Southwestern Atlantic: constraints to paleoclimate reconstructions
Abstract: Stable isotopes have been widely used in the literature both to discuss current ocean circulation processes, as well as to reconstitute paleoceanographic parameters. The distribution of oxygen and deuterium stable isotopes in seawater (δ18Osw and δDsw) at the Western Tropical South Atlantic border was investigated to better understand the main fr

9. Biomass and abiotic variables change in phytotelmic environment in the tank-bromeliad Nidularium longiflorum Ule in tropical forest
Resumo Objetivo Fitotelma desempenha um papel importante no crescimento das plantas e funcionamento do ecossistema, mas este microcosmo aquático natural é pouco investigado. O objetivo do presente estudo foi avaliar as variações sazonais (estações seca e chuvosa) e espaciais (trilha florestal e córrego) do fitotelma de Nidularium longiflorum, bromél

10. Assessment of the dendrochronological potential of Licaria bahiana Kurz, an endemic laurel of lowland Atlantic forests in Brazil
ABSTRACT The Atlantic Forest of southeastern Brazil has been considered to have the highest number of tree species per hectare in the world. Assessing the influence of climate on tropical tree species is a priority in the face of ongoing climate change, and for which dendrochronological studies have been important. We address the dendrochronological potentia

11. An anthropological analysis about primatology – Reports of a particular human-animal relationship with Capuchin monkeys
Abstract: This ethnography is about a particular human-animal relationship based on primatological research on groups of wild robust capuchin monkeys living in Parque Estadual Carlos Botelho (Brazil), one of the largest preserved areas of Atlantic Tropical Forest in the world. It emphasizes the complex situations that highlight the difficulty of making this

12. Sexual Systems of Plants in a Brazilian Montane Forest
ABSTRACT In this study, vegetation reproduction has been investigated in order to understand aspects of speciation, structuring and composition of plant communities. Thus, we sought to characterize the frequency of sexual systems from species recorded in seed rain occurring in a tropical rainforest (Atlantic Forest) in Caparaó National Park, Espírito Santo
