TL;DR: Functional composition and functional diversity were the principal factors explaining plant productivity, plant percent nitrogen, plant total nitrogen, and light penetration in grassland plots.

TL;DR: In both lakes and terrestrial systems, herbivores should have low growth efficiencies when consuming autotrophs with typical carbon-to-nutrient ratios and stoichiometric constraints on herbivore growth appear to be qualitatively similar and widespread in both environments.

TL;DR: There is reasonable empirical evidence to suggest that genetic differentiation through rapid evolutionary change is important in plant invasions, and conceptual and methodological issues associated with cross-continental comparisons are discussed.

TL;DR: Experimental reductions in grassland plant richness increase ecosystem vulnerability to invasions by plant species, enhance the spread of plant fungal diseases, and alter the richness and structure of insect communities, suggesting that the loss of basal species may have profound effects on the integrity and functioning of ecosystems.

TL;DR: In this paper, the concentration of resveratrol was measured in selected wines using HPLC and spectrophotometry, and it was found that geographic origin, variety, growing methods, and winemaking procedures all seemed to affect reserveratrol concentration.
