1. Análise das mudanças na vegetação nativa da apa Lago de Palmas
Resumo Neste estudo propõe-se conhecer a dinâmica da vegetação de Cerrado e Floresta Estacional, no período de 2000 a 2017, na Área de Preservação Ambiental (APA) Lago de Palmas, utilizando-se imagens do satélite Landsat e o software livre Spring 5.5.3. Foram construídos dois mapas temáticos da área estudada para estimar, por meio de análise com

2. Assemblage of drosophilids (Diptera, Drosophilidae) inhabiting flooded and nonflooded areas in the extreme South of Brazil
ABSTRACT Several studies on the potential use of drosophilid assemblages as bioindicator systems have been carried out in the last years. Nevertheless, the successful application of these organisms in these systems requires adequate filling of several knowledge gaps. In this sense, little is known about drosophilid assemblages in wetlands and flooded areas.

3. Species richness and composition of epiphytic bryophytes in flooded forests of Caxiuanã National Forest, Eastern Amazon, Brazil
ABSTRACT This study aimed to compare the richness and composition of the epiphytic bryoflora between várzea and igapó forests in Caxiuanã National Forest, Brazilian Amazon. Bryophytes were collected on 502 phorophytes of Virola surinamensis. Average richness per phorophyte and composition between forests and between dry and rainy periods was tested by two

4. Alkaloids and biological activity of beribá (Annona hypoglauca)
ABSTRACT Annona hypoglauca Mart., Annonaceae, popularly known as “beribá”, was collected in flooded areas of the Amazonian Rain Forest. The crude extract obtained from this species was found to be cytotoxic against human cancer cells. Chemical information on A. hypoglauca is scarce. So, the present work aimed the isolation and identification of its alka

5. Isotopic variation among Amazonian floodplain woody plants and implications for food-web research
Isotopic variation within food sources adds uncertainty to models intended to reconstruct trophic pathways. Understanding this variation is pivotal for planning sampling protocols for food-web research. This study investigates natural variation in C and N stable isotopes among plant species in two western Amazon flooded forests with contrasting watershed bio

6. New classification of natural breeding habitats for Neotropical anophelines in the Yanomami Indian Reserve, Amazon Region, Brazil and a new larval sampling methodology
Here we present the first in a series of articles about the ecology of immature stages of anophelines in the Brazilian Yanomami area. We propose a new larval habitat classification and a new larval sampling methodology. We also report some preliminary results illustrating the applicability of the methodology based on data collected in the Brazilian Amazon ra

7. Structure and phytogeographic relationships of swamp forests of Southeast Brazil
Swamp forests are associated with soils that are saturated or inundated because of a high water table. In Brazil, little is known about the plant ecology of such forests. In this paper, we aimed to describe the phytosociological structure of the tree layer of swamp forests in Restinga de Jurubatiba National Park, in the northern part of the state of Rio de J

8. O efeito do solo, inundação e topografia sobre as campinaranas inundáveis na Amazônia
Little is known about the factors that determine the spatial variation in structure, floristic composition and diversity in the Amazon Campinaranas. The Campinaranas are characterized by predominantly oligotrophic sandy soils. In the Negro River basin, they occur in a mosaic of grassland formations, forest and savanna, often associated with flooding. To infe

9. Fenología reproductiva y productividad de Oenocarpus bataua (Mart.) en bosques inundables del Chocó Biogeográfico, Colombia
Oenocarpus bataua (Mart.) is a palm species forming highly dense stands in flooded forests of the Chocó Biogeographic region. This species is considered promising because its fruits contain protein and high quality oil; therefore, periodic harvests of fruits are a potential source of food and income to local communities and could contribute to improve their

10. Feeding habits of giant otters Pteronura brasiliensis (Carnivora: Mustelidae) in the Balbina hydroelectric reservoir, Central Brazilian Amazon
This study aimed to identify the diet of giant otters, Pteronura brasiliensis (Zimmermann, 1780) in the Balbina reservoir (01º55'S, 59º29'W), to compare it with literature data on the diet of giant otters from non-dammed areas, and to verify the effects of the seasonal changes in water levels on the feeding habits of Balbina otters. A total of 254 feces sa

11. Vegetation and soil gradient in the restinga forest in Espirito Santo, Brazil / Gradiente vegetacional e pedológico em floresta de restinga no Espírito Santo, Brasil
The Restingas are ecosystems that occur in sandy soils deposited during the Quaternary. These are known to have a high diversity of vegetation, but few studies provide information on abiotic factors determining this diversity. This study aimed to: (i) assess the influence of the chemical aspects, physical soil and flooding in phytophysionomic determination,

The study have been developed in two fragments of permanently flooded Upper Montane Ombrophylous forest, located in the Itacolomi State Park, Ouro Preto, state of Minas Gerais, Brazil. This phytophisiognomy have a naturally fragmented distribution, but in several different of brazilian physiographic conditions. Still does not know a real covered area of this
