  • Forests are sinks for the neurotoxic mercury, but the sinks have large uncertainties. Our direct gaseous elemental mercury (GEM) exchange measurements show that GEM exchange includes complex patterns of multiple pathways to different ecosystem compartments varying over time

  • In the polar atmosphere, non-reactive gaseous elemental mercury is converted to a highly reactive form of mercury by halogens such as bromine. Measurements over the Dead Sea suggest that bromine also triggers reactive mercury formation over the mid-latitude ocean.

  • Fallout radionuclide (FRN) chronometry reveals that accumulation of Hg in soils is five times higher than reported in sediment or peat archives. This confirms that global forest soils are strong and stable sinks of gaseous elemental mercury (GEM).

  • Salvage logging has become a common practice to gain economic returns from naturally disturbed forests, but it could have considerable negative effects on biodiversity. Here the authors use a recently developed statistical method to estimate that ca. 75% of the naturally disturbed forest should be left unlogged to maintain 90% of the species unique to the area.

  • Cities may host surprisingly diverse and functionally distinct biological communities. This global analysis on 5302 vertebrate and invertebrate species finds evidence of 4 trait syndromes in urban animal assemblages, modulated by spatial and geographic factors.

  • Terrestrial vegetation contributes to the seasonal variation of atmospheric mercury concentrations, according to analyses of atmospheric trace gas dynamics and satellite data. The data show that the photosynthetic activity of vegetation correlates with atmospheric mercury.

  • Mercury, a semi-volatile and globally abundant pollutant, is transported through the atmosphere and taken up by vegetation. This Review discusses the mechanisms of vegetation mercury uptake and the role of vegetation in the mercury cycle, highlighting its importance for redistribution in the terrestrial environment and influence on atmospheric mercury concentrations and deposition to oceans.
