Effects of elevated ultraviolet radiation on primary metabolites in selected alpine algae and cyanobacteria
Extremophilic green algae and cyanobacteria are the most abundant species in high mountain habitats, where rough climate conditions such as temperature differences, limited water retention and high ultraviolet (UV) radiation are the cause for a restricted biological diversity in favor of a few specialized autotrophic microorganisms. In this study, we investigated four algal species from alpine ...
متن کاملClimate change and physical disturbance manipulations result in distinct biological soil crust communities.
Biological soil crusts (biocrusts) colonize plant interspaces in many drylands and are critical to soil nutrient cycling. Multiple climate change and land use factors have been shown to detrimentally impact biocrusts on a macroscopic (i.e., visual) scale. However, the impact of these perturbations on the bacterial components of the biocrusts remains poorly understood. We employed multiple long-...
متن کاملUltraviolet radiation shapes seaweed communities
Stratospheric ozone depletion and the concomitant increase in irradiance of ultraviolet-B radiation (UVB) at the earth’s surface represent major threats to terrestrial and aquatic ecosystems. In costal rocky shore environments, seaweeds constitute a group of organisms of particular significance to ecosystem function. Thus, impairment of seaweed performance by UVB-exposure may result in severe c...
متن کاملStructure and function of alpine and arctic soil microbial communities.
Cultivation-independent molecular phylogenetic techniques are now widely employed to examine environmental microbial diversity; however, the relationship between microbial community structure and ecosystem function is unclear. This review synthesizes cultivation-independent views of microbiological diversity with our current understanding of nutrient dynamics in alpine and arctic soils. Recentl...
متن کاملSelective isolation of blue-green algae from water and soil.
For the isolation of blue-green algae from soil and fresh water, temperature is a selective factor of major importance. In a nutritionally non-selective mineral medium, which at 25" supported growth of blue-green algae and of many eucaryotic algae, the development of eucaryotic algae was almost completely suppressed by incubation at 35". Both the number and variety of blue-green algae recoverab...
