13. Litterfall Deposition and Decomposition in an Atlantic Forest in Southern Goiás
ABSTRACT Brazilian biomes have been severely threatened and their conservation depends on the knowledge of intrinsic ecological processes and correct phytophysiognomy identification of legal protection purposes. Litterfall deposition and decomposition patterns associated with taxonomic composition, climate, soil and relief can be considered important tools

14. Pteridophytes as ecological indicators: an overview
RESUMO As pteridófitas apresentam grande potencial como indicadores ecológicos (EIs), mas pouco explorado, mostrado apenas em trabalhos esparsos. Portanto, para analisar esse potencial, revisamos artigos publicados, sites ou livros com pteridófitas como EIs, realizando buscas em cinco bases de dados acadêmicas e no Google. Selecionamos 134 estudos, feito

15. A snapshot of the limnological features in tropical floodplain lakes: the relative influence of climate and land use
Resumo Objetivo O objetivo desse estudo foi investigar a influência relativa do clima (temperatura e precipitação) e do uso da terra nas características limnológicas de 30 lagoas da planície de inundação do Rio Araguaia, no Brasil Central, um importante rio que drena no Cerrado brasileiro. Métodos As lagoas foram amostradas em um mesmo período,

16. Seasonal dynamics of vegetation indices as a criterion for grouping grassland typologies
ABSTRACT: This study aimed to characterize the average seasonal pattern of the vegetation in southern grassland in Brazil, and the variability found in the time series of vegetation indices. It also sought to identify similarities in the seasonal pattern of different grassland typologies. Moderate Resolution Imaging Spectroradiometer (MODIS), Normalized Diff

17. Leishmaniose visceral e sua relação com fatores climáticos e ambientais no Estado do Tocantins, Brasil, 2007 a 2014
Resumo: A leishmaniose visceral (LV) pode ser influenciada por fatores climáticos e ambientais. Tocantins é o estado com mais incidência no Brasil, contribuindo para o aumento dos casos na macrorregião Norte. Este estudo tem objetivo de identificar a correlação entre a taxa de incidência de LV e fatores climáticos e ambientais, nos municípios do Est

18. Spatial and Temporal Potential Groundwater Recharge: the Case of the Doce River Basin, Brazil
ABSTRACT: Little is known about the groundwater recharge potential of weathered tropical catchments, where increasing water uptake is widespread to meet various water demands. This study aimed to estimate the volume of groundwater recharge of the Doce River Basin, Minas Gerais, Brazil. The BALSEQ model was applied to calculate the water balance over a period

19. Paleoenvironmental Characterization of a High-Mountain Environment in the Atlantic Forest in Southeastern Brazil
ABSTRACT: Records of changes in the phytosociological structure of vegetation can be observed more clearly in soils that have more significant accumulation of organic matter, like those occurring in high-mountain environments. The aim of this study was to characterize soils formed in high-mountain environments in the Itatiaia National Park (INP), state of Ri

20. Distribution, ecology, and reproduction of bryophytes in a humid enclave in the semiarid region of northeastern Brazil
ABSTRACT The ready availability of water resources distinguishes the humid forest of Chapada do Araripe, Ceará State, Brazil, from the semiarid vegetation around it. The regional climate demonstrates a marked seasonality of rainfall that affects the ecological strategies of the species found there. We studied the bryophytes of the humid forest of Chapada do

21. Two approaches to calculate TVDI in humid subtropical climate of southern Brazil
ABSTRACT: Soybean crops occupy most areas in Rio Grande do Sul State and are highly dependent on rainfall since most of them are non-irrigated. Rainfall during the harvest period is often insufficient to meet the water demand, making water indicators an important tool for the crops. This study compared two approaches in the parameterization process of TVDI (

22. ANALYSIS OF THE PHENOLOGY DYNAMICS OF BRAZILIAN CAATINGA SPECIES WITH NDVI TIME SERIES
ABSTRACT In Brazil there are six well-defined biomes and the Caatinga represents 9.92% of the total area. This biome is exclusively Brazilian and very rich in biodiversity. Because it has low resistance to human interference is necessary to know the important factors in monitoring the biome. Vegetation coverage and climate are two of these factors, as they i

23. Paleodistribution of Neotropical species of Erythroxylum (Erythroxylaceae) in humid and dry environments
ABSTRACT Variation in environmental conditions during the Quaternary period served as important filters for the maintenance of vegetation types and for determining the composition of the current biota. We analyzed oscillations in the distributions of different vegetation types in Brazil during the Quaternary period using species of the genus Erythroxylum (Er

24. Landslides Zonation Hazard: relation between geological structures and landslides occurrence in hilly tropical regions of Brazil
ABSTRACT This paper presents a new approach of landslides zonation hazard studies, based on an integrated study of structural data along with geomorphological and external factors, in a hilly regions of Brazil, covered by a tropical humid rain-forest, called Serra do Mar. The Serra do Mar consists of a hilly region along the east coast of Brazil, with high s
