Drought-induced Amazonian wildfires instigate a decadal-scale disruption of for...
Silva, Camila V.J.; Aragao, L. E.O.C.; Barlow, Jos; Espírito-Santo, Fernando; Young, Paul J.; Anderson, Liana Oighenstein; Berenguer, ErikaDrought-induced wildfires have increased in frequency and extent over the tropics. Yet, the long-term (greater than 10 years) responses of Amazonian lowland forests to fire disturbance are poorly known. To understand post-fire forest biomass dynamics, and to assess the time required for fire-affected forests to recover to pre-disturbance levels, we combined 16 single with 182 multiple forest census into a uniqu...
Spatial distribution and functional significance of leaf lamina shape in Amazon...
Malhado, Ana Cláudia Mendes; Whittaker, Robert J.; Malhi, Yadvinder Singh; Ladle, Richard James; ter Steege, H.; Butt, Nathalie; Aragao, L. E.O.C.Leaves in tropical forests come in an enormous variety of sizes and shapes, each of which can be ultimately viewed as an adaptation to the complex problem of optimising the capture of light for photosynthesis. However, the fact that many different shape "strategies" coexist within a habitat demonstrate that there are many other intrinsic and extrinsic factors involved, such as the differential investment in sup...
Climate seasonality limits leaf carbon assimilation and wood productivity in tr...
Wagner, Fabien H.; Hérault, Bruno; Bonal, Damien; Stahl, Clément; Anderson, Liana Oighenstein; Baker, Timothy R.; Sebastian Becker, GabrielThe seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy p...
Spatial trends in leaf size of amazonian rainforest trees
Malhado, Ana Cláudia Mendes; Malhi, Yadvinder Singh; Whittaker, Robert J.; Ladle, Richard James; ter Steege, H.; Phillips, Oliver L.; Butt, NathalieLeaf size influences many aspects of tree function such as rates of transpiration and photosynthesis and, consequently, often varies in a predictable way in response to environmental gradients. The recent development of pan-Amazonian databases based on permanent botanical plots has now made it possible to assess trends in leaf size across environmental gradients in Amazonia. Previous plot-based studies have sho...
Sensor modis : características gerais e aplicações
Latorre, Marcelo Lopes; Anderson, Liana Oighenstein; Shimabukuro, Yosio Edemir; Carvalho Júnior, Osmar Abílio deO presente trabalho tem como propósito realizar uma abordagem geral sobre um dos principais sensores, denominado MODIS (Moderate Resolution ImagingSpectroradiometer), desenvolvido pela NASA, com o objetivo de determinar como aTerra está mudando e quais as conseqüências para a vida neste planeta, desenvolvendo um entendimento de seu funcionamento como um sistema único e interligado. Seusprodutos permitirão um mo...
