Autotrophy in Groundwater Ecosystems
The major role in global net CO2 fixation plays photosynthesis of green plants, algae and cyanobacteria, but other microorganisms are also important concerning autotrophy; i.e. autotrophic microorganisms can be found in most bacterial groups (Eubacteria) and there are even numerous representatives within the Archaea. CO2 fixation is not only one of the world’s most important biogeochemical proc...
متن کاملMapping Groundwater Dependent Ecosystems in California
BACKGROUND Most groundwater conservation and management efforts focus on protecting groundwater for drinking water and for other human uses with little understanding or focus on the ecosystems that depend on groundwater. However, groundwater plays an integral role in sustaining certain types of aquatic, terrestrial and coastal ecosystems, and their associated landscapes. Our aim was to illumina...
متن کاملStygofauna enhance prokaryotic transport in groundwater ecosystems
More than 97% of the world's freshwater reserves are found in aquifers, making groundwater one of the most important resources on the planet. Prokaryotic communities in groundwater underpin the turnover of energy and matter while also maintaining groundwater purity. Thus, knowledge of microbial transport in the subsurface is crucial for maintaining groundwater health. Here, we describe for the ...
متن کاملVibrational resonance in groundwater-dependent plant ecosystems
We report the phenomenon of vibrational resonance in a single species and a two species models of groundwater-dependent plant ecosystems with a biharmonic oscillation (with two widely different frequencies ω and Ω, Ω ≫ ω) of the water table depth. In these two systems, the response amplitude of the species biomass shows multiple resonances with different mechanisms. The resonance occurs at both...
متن کاملUsing Boreholes as Windows into Groundwater Ecosystems
Groundwater ecosystems remain poorly understood yet may provide ecosystem services, make a unique contribution to biodiversity and contain useful bio-indicators of water quality. Little is known about ecosystem variability, the distribution of invertebrates within aquifers, or how representative boreholes are of aquifers. We addressed these issues using borehole imaging and single borehole dilu...
