Effects of natural and experimental drought on soil fungi and biogeochemistry in an Amazon rain forest

نویسندگان

چکیده

Abstract Microbiota are essential components of the soil, driving biogeochemical cycles. Fungi affect decomposition and biotic interactions with plants across scales. Climate projections suggest that extended dry seasons may transform sensitive rain forests into savanna-like vegetation, consequent changes in biogeochemistry. Here we compare impacts natural seasonality 14 years partial throughfall exclusion an Amazonian forest, focussing on soil fungal functional diversity, extracellular enzyme activities (EEA) their implications for nutrient dynamics. Large diversity group composition occur response to drought, a conspicuous increase abundance dark-septate fungi decrease pathogens. The high EEA control (non droughted) suppression drought treatment, together increased implied nitrogen demand season induced by experimental changed microbiota activity signal pending shift functioning forest.

abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...

Effects of experimental drought on soil respiration and radiocarbon efflux from a temperate forest soil

Soil moisture affects microbial decay of SOM and rhizosphere respiration (RR) in temperate forest soils, but isolating the response of soil respiration (SR) to summer drought and subsequent wetting is difficult because moisture changes are often confounded with temperature variation. We distinguished between temperature and moisture effects by simulation of prolonged soil droughts in a mixed de...

Experimental drought in a tropical rain forest increases soil carbon dioxide losses to the atmosphere.

Climate models predict precipitation changes for much of the humid tropics, yet few studies have investigated the potential consequences of drought on soil carbon (C) cycling in this important biome. In wet tropical forests, drought could stimulate soil respiration via overall reductions in soil anoxia, but previous research suggests that litter decomposition is positively correlated with high ...
