1. Biomass production of the aquatic macrophyte Ceratopteris pteridoides (Hook.) Hieron (Pteridaceae) in nutrient addition treatments
ABSTRACT Aquatic macrophytes are a key group in flooded areas due to their high primary productivity, and several species present in the Amazonian floodplains have potential for human food use. This study evaluated biomass production and nutrient levels in fronds of Ceratopteris pteridoides (Pteridaceae), under the following nutritional treatments: (T1) arte

2. Implications of global climate change for the development and ecological interactions between two key Amazonian aquatic macrophytes
ABSTRACT Amazon wetlands are among the most vulnerable ecosystem to be impacted by climate change, which may increase the frequency of extreme droughts and floods. We used Eichhornia crassipes and Pistia stratiotes, two abundant aquatic plants in the Amazon floodplains, to evaluate the effects of combined temperature and [CO2] increase on growth, physiology

3. Richness, abundance and microhabitat use by Ardeidae (Aves: Pelecaniformes) during one seasonal cycle in the floodplain lakesof the lower Amazon River
ABSTRACT The Amazon floodplains become periodically submerged as result of seasonal changes in the water levels throughout the year. These changes influence the availability of microhabitats and consequently the abundance of organisms in these ecosystems. In this study we investigated 1) how changes in the water level affect the richness and abundance of ard

4. Myriapods (Arthropoda, Myriapoda) in the Pantanal of Poconé, Mato Grosso, Brazil
Resumo: O Pantanal de Mato Grosso é uma das maiores e mais importantes planícies de inundação do mundo, em relação à sua biodiversidade e aos seus indispensáveis serviços ecológicos em escalas locais, regionais e globais. Apesar dessa importância, existem, ainda, muitas lacunas sobre o conhecimento de sua biodiversidade, bem como de seus mecanismo

5. Structural differences in mammal assemblages between savanna ecosystems of the Colombian Llanos
Abstract The Colombian Orinoquia region is characterized by a high diversity of mammals, which is associated with complex ecosystems that include large extensions of Neotropical savannas (known locally as “Llanos Orientales”). Despite accelerated anthropogenic transformations in savanna ecosystems, the knowledge to design effective conservation strategie

6. Technical contributions to territorial planning and the use of ecosystemic services in a hydrographic basin with a water deficit in the Atlantic Rainforest of Brazil
Resumo A bacia do rio Dois Rios (R2R) (3.159 km²) recolhe os efeitos climáticos e ambientais típicos de zonas situadas a sotavento de cadeias montanhosas. Tem balanço hídrico deficitário, havendo poucos e específicos locais úmidos. Este estudo identifica, espacializa, caracteriza e agrupa as planícies de inundação com maior habilidade em produzir

7. Composition, diversity and structure of vascular epiphytes in two contrasting Central Amazonian floodplain ecosystems
ABSTRACT Research focusing on assemblages of vascular epiphytes in the Amazon are scarce. This is especially true for Amazonian floodplain forests, for which only two previous studies have been published. We compared composition, richness and structure of epiphyte assemblages in white-water and black-water floodplains (várzea and igapó) in Central Amazonia

8. Remoção/exportação de nutrientes de esgoto doméstico utilizando plantas ornamentais : Hedychium coronarium, Heliconia psittacorum, Cyperus alternifolius e Colocasia esculenta / Domestic sewage nutrients removal/export using ornamental plants : Hedychium coronarium, Heliconia psittacorum, Cyperus alternifolius and Colocasia esculenta
O presente estudo trabalhou com leitos cultivados (LC) avaliando a capacidade de retenção exportação de nutrientes, nitrogênio e fósforo, a partir da poda das plantas. Os LC foram utilizados no pós-tratamento de efluentes de esgoto doméstico pós reatores anaeróbios compartimentados (RAC) utilizando plantas ornamentais: Hedychium coronarium; Helicon

9. Concordância espacial da assembléia de peixes de uma planície de inundação / Spacial concordance of fish assemblage of a floodplain
O conceito de sincronia pode ser definido como o grau em que diferentes sistemas biológicos mostram evoluções temporais similares. Flutuações sincrônicas nas espécies são atribuídas à influência de fatores ambientais ou dispersão de indivíduos (distância entre ambientes). Nesse contexto o objetivo deste estudo foi quantificar a similaridade da

10. Concordância espacial da assembléia de peixes de uma planície de inundação / Spacial concordance of fish assemblage of a floodplain
The synchrony concept can be defined like the degree that different biologics systems show similar temporal evolution. Synchronies fluctuations in species are attributed to influence of ambient factors or individuals dispersion (distance of ambient). Thus, the objective this study was measured the ichthyofauna similarity among six environment of Parana River

11. São Paulo in the middle of the marginals: the paulistan image reflectedon the rivers Pinheiros and Tietê / São Paulo no centro das marginais: a imagem paulistana refletida nos Rios Pinheiros e Tietê
The rivers Pinheiros and Tietê have always stood out as a unique landscape on the hilly plateau over which São Paulo has settled. In a process of transformation already begun at the end of the 19th century and whose apex occurred during the 1940s and 1960s decades - when these creeks were channelized and rectified and a pair of urban freeways were built on

12. Consumo alimentar doméstico em populações caboclas assentadas em três diferentes ambientes amazônicos: uma análise comparativa / Household food consumption in Caboclo populations settled in three different Amazonian environments: a comparative analysis
The Amazon has been the scene of numerous discussions about the environment´s role in the structuring of human societies. Until recently, in the majority of the discussions about the nature of the environmental constraints in the Amazon, the choice of single limiting factors has been a constant. In these discussions, the Caboclo societies are very important
