Hydraulic redistribution of soil water by roots affects whole-stand evapotranspiration and net ecosystem carbon exchange.
*Hydraulic redistribution (HR) of water via roots from moist to drier portions of the soil occurs in many ecosystems, potentially influencing both water use and carbon assimilation. *By measuring soil water content, sap flow and eddy covariance, we investigated the temporal variability of HR in a loblolly pine (Pinus taeda) plantation during months of normal and below-normal precipitation, and ...
متن کاملAfforestation or intense pasturing improve the ecological and economic value of abandoned tropical farmlands
Increasing demands for livelihood resources in tropical rural areas have led to progressive clearing of biodiverse natural forests. Restoration of abandoned farmlands could counter this process. However, as aims and modes of restoration differ in their ecological and socio-economic value, the assessment of achievable ecosystem functions and benefits requires holistic investigation. Here we comb...
متن کاملMid-latitude afforestation shifts general circulation and tropical precipitation.
We show in climate model experiments that large-scale afforestation in northern mid-latitudes warms the Northern Hemisphere and alters global circulation patterns. An expansion of dark forests increases the absorption of solar energy and increases surface temperature, particularly in regions where the land surface is unable to compensate with latent heat flux due to water limitation. Atmospheri...
متن کاملRNAi targeting α - arrestins marginally Caenorhabditis elegans affects lifespan
α-arrestins are a family of proteins that are implicated in multiple Background: biological processes, including metabolism and receptor desensitization. Here, we sought to examine the roles of α-arrestins in the longevity Methods: of through an RNA interference screen. We Caenorhabditis elegans Results: found that knocking down each of 24 out of total 29 α-arrestins had C. elegans small or no ...
متن کاملExperimental Air Warming of a Stylosanthes capitata, Vogel Dominated Tropical Pasture Affects Soil Respiration and Nitrogen Dynamics
Warming due to global climate change is predicted to reach 2°C in tropical latitudes. There is an alarming paucity of information regarding the effects of air temperature on tropical agroecosystems, including foraging pastures. Here, we investigated the effects of a 2°C increase in air temperature over ambient for 30 days on an established tropical pasture (Ribeirão Preto, São Paulo, Brazil) do...
