Disappearing Arctic lakes.
Historical archived satellite images were compared with contemporary satellite data to track ongoing changes in more than 10,000 large lakes in rapidly warming Siberia. A widespread decline in lake abundance and area has occurred since 1973, despite slight precipitation increases to the region. The spatial pattern of lake disappearance suggests (i) that thaw and "breaching" of permafrost is dri...
متن کاملRecent primary production increases in arctic lakes
[1] A new application of reflectance spectroscopy enables inferences of lake sediment chlorophyll a concentrations and hence of historical trends in lacustrine primary production. In a survey of six arctic lakes on Baffin Island (Nunavut, Canada), pronounced increases of spectrally-inferred chlorophyll a concentrations are consistently expressed in sediments deposited during the 20th century. C...
متن کاملInteractive effects of chemical and biological controls on food-web composition in saline prairie lakes
Salinity is restricting habitatability for many biota in prairie lakes due to limited physiological abilities to cope with increasing osmotic stress. Yet, it remains unclear how salinity effects vary among major taxonomic groups and what role other environmental parameters play in shaping food-web composition. To answer these questions, we sampled fish, zooplankton and littoral macroinvertebrat...
متن کاملModeling methane emissions from arctic lakes: Model development and sitelevel study
To date, methane emissions from lakes in the pan-arctic region are poorly quantified. In order to investigate the response of methane emissions from this region to global warming, a process-based climate-sensitive lake biogeochemical model was developed. The processes of methane production, oxidation, and transport were modeled within a one-dimensional sediment and water column. The sizes of C-...
متن کاملSwitchable electrode interfaces controlled by physical, chemical and biological signals.
Electrode interfaces functionalized with various signal-responsive materials have been designed to allow switchable properties of the modified electrodes. External signals of different nature (electrical potential, magnetic field, light, chemical/biochemical inputs) were applied to reversibly activate-deactivate the electrode interfaces upon demand. Multifunctional properties of the modified in...
