Fragmentação florestal e suas potenciais implicações para a gestão da bacia do ...
Costa, Jamerson Souza da; Rodrigues, Liange de Sousa; Silva, Aline Gabriela Castro da; Reis, Thatierlen da Costa; Melo, Maria da Glória Gonçalves deA intensificação do desmatamento e a consequente fragmentação da paisagem natural em bacias hidrográficas urbanas e periurbanas afetam todo o sistema eco-hidrológico, aumentando a necessidade de entendimento de como essas mudanças podem impactar sua sustentabilidade. Nesse sentido, o presente estudo avaliou as potenciais implicações da fragmentação florestal para a gestão da bacia do Ta...
Towards sustainability: Allowance rights for using water resources in Amazonas ...
Muniz, J?ssica; Melo, Maria da Glória Gonçalves de; Liberato, Maria Astrid Rocha; Wahnfried, Ingo D.; Vieira, GilThe water use permit is one of the instruments of the National and State Policy of Water Resources in Brazil through which the government authorizes the user to withdraw water or to make hydraulic interferences in water bodies necessary for their activities, guaranteeing the right of access to these resources. In the state of Amazonas, the Water Resources Policy (PERH) was reformulated by Law 3,167 of 2007, whi...
Root anoxia effects on physiology and emissions of volatile organic compounds (...
Bracho-Nuñez, Araceli; Knothe, Nina Maria; Costa, Wallace R.; Liberato, Maria Astrid Rocha; Kleiss, Betina; Rottenberger, StefanieVolatile organic compound (VOC) emissions are affected by a variety of biotic and abiotic factors such as light intensity, temperature, CO2 and drought. Another stress factor, usually overlooked but very important for the Amazon region, is flooding. We studied the exchange of VOCs in relation to CO2 exchange and transpiration of 8 common tree species from the Amazonian floodplain forest grown up from seeds usin...
Leaf level emissions of volatile organic compounds (VOC) from some Amazonian an...
Bracho-Nuñez, Araceli; Knothe, Nina Maria; Welter, Saskia; Staudt, Michael; Costa, Wallace R.; Liberato, Maria Astrid RochaEmission inventories defining regional and global biogenic volatile organic compounds (VOC) emission strengths are needed to determine the impact of VOC on atmospheric chemistry (oxidative capacity) and physics (secondary organic aerosol formation and effects). The aim of this work was to contribute with measurements of tree species from the poorly described tropical vegetation in direct comparison with the qui...
