Lichens occur in most terrestrial ecosystems; they are often present as minor contributors,
but in some forests, drylands and tundras they can make up most of the ground layer …

Since lichens lack roots and take up water, solutes and gases over the entire thallus surface,
these organisms respond more sensitively to changes in atmospheric purity than vascular …

Bulk aerosols (> 1μm) were collected continuously above the canopy at the Howland
Experimental Forest, Maine, USA from May to October 2002. Each sample integrated over …

Phototrophic communities of photosynthetic algae or cyanobacteria and heterotrophic
bacteria or fungi are pervasive throughout the environment. How interactions between …

Critical loads (CLs) define maximum atmospheric deposition levels apparently preventative
of ecosystem harm. We present first nitrogen CLs for northwestern North America's maritime …

A one-year observation of aerosols on a remote island was conducted and saccharides
were applied to reveal the behaviors of organic aerosol in the East China Sea (ECS). The …

Findings from nitrogen (N) manipulation studies have provided strong evidence of the
detrimental impacts of elevated N deposition on the structure and functioning of heathland …

An improved method is described for the quantification of primary sugars, sugar alcohols
and anhydrosugars in atmospheric aerosols, making use of separation by high-performance …

In order to learn more about nitrogen (N) acquisition in lichens, and to see whether different
lichens differ in their affinity to various N sources, N uptake was measured in 14 various …

Nitrogen (N) deposition has increased globally over the last 150 years and further increases
are predicted. Epiphytic lichens decline in abundance and diversity in areas with high N …
