Mountain lakes are often situated in protected natural areas, a feature that leads to their role
as sentinels of global environmental change. Despite variations in latitude, mountain lakes …

Abstract Transparent Exopolymer Particles (TEP) have received considerable attention
since they were first described in the ocean more than 20 years ago. This is because of their …

Aerosolization of soil-dust and organic aggregates in sea spray facilitates the long-range
transport of bacteria, and likely viruses across the free atmosphere. Although long-distance …

Many studies have shown that species sorting, that is, the selection by local environmental
conditions is important for the composition and assembly of bacterial communities. On the …

Arid ecosystems cover∼ 40% of the Earth's terrestrial surface and store a high proportion of
the global nitrogen (N) pool. They are low-productivity, low-biomass, and polyextreme …

Sandstorms are a natural metrological phenomenon, frequently occurring in many arid and
semi-arid regions of the world. The sandstorm dust contains environmental pollutants …

Anthropogenic activities have significantly altered atmospheric chemistry and changed the
global mobility of key macronutrients. Here we show that contemporary global patterns in …

Remote lakes are usually unaffected by direct human influence, yet they receive inputs of
atmospheric pollutants, dust, and other aerosols, both inorganic and organic. In remote …

Sand and dust storms (SDS) are wind erosion events typically associated with dryland
regions, although they can occur in most environments and their impacts are frequently …

Present day lead pollution is an environmental hazard of global proportions. A correct
determination of natural lead levels is very important in order to evaluate anthropogenic lead …
