13. Stability of Soil Moisture Patterns Retrieved at Different Temporal Resolutions in a Tropical Watershed
ABSTRACT Above and underground hydrological processes depend on soil moisture (SM) variability, driven by different environmental factors that seldom are well-monitored, leading to a misunderstanding of soil water temporal patterns. This study investigated the stability of the SM temporal dynamics to different monitoring temporal resolutions around the borde

14. Environmental fragility and vegetation cover dynamics in the Lapa Grande State Park, MG, Brazil
Abstract: The environmental fragility analysis evaluates the susceptibility of an environment to degradation. Thus, the goals of this work are to analyze and map the environmental fragility of the Lapa Grande State Park (PELG), Brazil, and its buffer zone (ZA) and also quantify the changes in the vegetation cover before and after the implementation of the PE

15. Decomposition and Nutrient Release of Cover Crops in Mango Cultivation in Brazilian Semi-Arid Region
ABSTRACT Knowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems. This work aimed to evaluate whether soil tillage and the choice of cover crops cultivated in the interrows can be te

16. Influence of Urbanization on the Dynamics of the Urban Vegetation Coverage Index (VCI) in Erechim (RS)
ABSTRACT Vegetation fragments located in urban perimeters provide better environmental conditions for biological diversity and human well-being. The aim of this study was to evaluate the Vegetation Coverage Index (VCI) of the urban perimeter of Erechim, RS, between years 2010 and 2015. Mapping was carried out using World View 2 and Pleiades satellites image

17. A Praça de Casa Forte: um jardim histórico, um patrimônio cultural do Brasil
RESUMO O jardim moderno brasileiro foi criado em Recife por Roberto Burle Marx na década de 1930. Ele concebia o jardim como uma reintegração estética dos elementos da natureza onde a vegetação era elemento principal. Com essa intenção, projetou treze jardins públicos entre 1935 e 1937, incluindo a Praça de Casa Forte, seu primeiro projeto. Sendo o

18. Shifting habitat mosaic: identification and mapping
Resumo O Mosaico de Habitat Móvel (SHM) refere-se às mudanças temporais no padrão espacial dos habitats, através dos pulsos de inundação e seca. Este trabalho teve por objetivo mapear a dinâmica de um Mosaico Móvel associado aos pulsos de inundação e seca, na Área de Proteção Ambiental do Banhado Grande (APABG). A realização desta pesquisa di

19. Relationship between the normalized difference vegetation index and leaf area in vineyards
ABSTRACT In vineyards, the monitoring of leaf area is used to guide management practices in order to produce grapes with quality and enological potential. Remote sensing has been used to estimate leaf area by means of vegetation indices. This work aimed at determining the temporal evolution of the Normalized Difference Vegetation Index (NDVI) while associati

20. FOREST DYNAMICS OF A SUB-XEROPHILOUS VEGETATION FORMATION IN CENTRAL PERU - CHANCHAMAYO VALLEY, PERU
RESUMO Pesquisas sobre os complexos processos de dinâmica da floresta nas florestas montanas e premontanas úmidas (600 a 3000 msnm) são escassas. Este estudo tem como objetivo contribuir com o conhecimento de mudanças na composição florística e dinâmica populacional de espécies lenhosas em um tipo de formação de planta sub-xerofílica imerso nas f

21. 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

22. Fire records in tree rings of Moquiniastrum polymorphum: potential for reconstructing fire history in the Brazilian Atlantic Forest
ABSTRACT Fire disturbance affects the composition, structure and dynamics of vegetation. Historical records of fire events exist in some places, but they are generally limited in temporal and spatial extent. Tree-ring research is a useful tool for fire history reconstruction and can contribute important long-term ecological data. We tested the hypotheses tha

23. Mangrove Soil in Physiographic Zones in the Sao Francisco River Estuary
ABSTRACT Mangrove ecosystem dynamics and diverse human activities have led to a need for studies that give us a better understanding of the peculiarities of their soils. The objective of this study was to evaluate the physical and chemical soil attributes of mangrove forests located in the São Francisco River estuary, related to local ecological conditions

24. Community structure and population dynamics of small mammals in an urban-sylvatic interface area in Rio de Janeiro, Brazil
ABSTRACT The Atlantic Forest is one of the most disturbed Brazilian biomes, with 183 out of 298 species of mammals occurring in the state of Rio de Janeiro. In this study, we aimed to characterize the diversity, community structure, and habitat use of small mammals in the FIOCRUZ Atlantic Forest Campus (CFMA), including areas of Pedra Branca State Park (PBSP
