TL;DR: It is shown that plant diversity effects dampen with increasing trophic level and degree of omnivory, and the results suggest that plant Diversity has strong bottom-up effects on multitrophic interaction networks, with particularly strong effects on lower trophIC levels.

TL;DR: Exposure to high concentrations of gaseous pollutants, SO2, NOx, and ozone has had no long-lasting direct effect on needles, and pathogens have only been secondary agents; deposition of sulfur, nitrate, and ammonium have significantly modified plant nutrition and soil chemistry.

TL;DR: In this paper, the authors describe the current hypotheses of how humidity and plant and soil water status may interact and regulate stomatal conductance and photosynthesis, and focus on the effects of 1. humidity, 2. leaf water potential and leaf turgor, and 3. soil Water status on leaf conductance, transpiration, and CO/sub 2/ assimilation.

TL;DR: The Biodiversity Exploratories (www.biodiversityexploratories.de ) as mentioned in this paper is a large-scale and long-term project for functional biodiversity, which includes a hierarchical set of standardized field plots in three different regions of Germany covering manifold management types and intensities in grasslands and forests.

TL;DR: A theoretical framework and global maps for relations between nitrogen-(N)-nutrition and stomatal conductance, gs' at the leaf scale and flUXe!1 of water vapor and carbon dioxide at the canopy scale are provided.
