Challenges Regionalizing Methane Emissions Using Aquatic Environments in the Amazon Basin as Examples

نویسندگان

چکیده

Key challenges to regionalization of methane fluxes in the Amazon basin are large seasonal variation inundated areas and habitats, wide variety aquatic ecosystems throughout basin, variability time space. Based on available measurements emission areal extent, seven types systems considered: streams rivers, lakes, seasonally flooded forests, savannas other interfluvial wetlands, herbaceous plants riverine floodplains , peatlands, hydroelectric reservoirs. We evaluate adequacy sampling field methods plus atmospheric measurements, as applied summarize published regional estimates using bottom-up top-down approaches, discuss current understanding biogeochemical physical processes environments their incorporation into mechanistic statistical models. Recommendations for further study elsewhere include application new remote sensing techniques, increased frequency duration, experimental studies improve processes, development models appropriate hydrological ecological conditions.

Annual Carbon Emissions from Deforestation in the Amazon Basin between 2000 and 2010

Reducing emissions from deforestation and forest degradation (REDD+) is considered one of the most cost-effective strategies for mitigating climate change. However, historical deforestation and emission rates-critical inputs for setting reference emission levels for REDD+-are poorly understood. Here we use multi-source, time-series satellite data to quantify carbon emissions from deforestation ...

Rickettsial Disease in the Peruvian Amazon Basin

Using a large, passive, clinic-based surveillance program in Iquitos, Peru, we characterized the prevalence of rickettsial infections among undifferentiated febrile cases and obtained evidence of pathogen transmission in potential domestic reservoir contacts and their ectoparasites. Blood specimens from humans and animals were assayed for spotted fever group rickettsiae (SFGR) and typhus group ...

Temporal variations in methane emissions from emergent aquatic macrophytes in two boreonemoral lakes

Methane (CH4) emissions via emergent aquatic macrophytes can contribute substantially to the global CH4 balance. We addressed temporal variability in CH4 flux by using the static chamber approach to quantify fluxes from plots dominated by two species considered to differ in flux transport mechanisms (Phragmites australis, Carex rostrata). Temporal variability in daily mean emissions from early ...
