Extrafloral nectar (EFN) is rich in sugars and amino acids and mediates the protection-for-food mutualism between EFN-plants and ants. We analyzed (via HPLC) 8 samples for the 3 EFN-tree species (Ailanthus altissima, Melia azedarach, Triadica coch...

We sampled trophobioses from 21 May to 20 August 2011 on site A. We selected in total 146 plots from tree diversity level 1, 2, 4, 8 and 16. Because there are only two plots with tree diversity 24, we did not study the highest available tree dive...

Trap nests (eigth traps per plot; four traps each attached to a wooden post; located at two randomly selected corners the corners of the central 10 x 10 m subplot; traps belonging to the same wooden post in a plot are marked with a "-" or left wit...

In all four seasons (summer 2008, autumn 2008, spring 2009 and winter 2010) the gravimetric soil water content of the mineral soil in up to 6 soil layers was determined. Soil sampling was performed in parallel with nitrate and ammonium extractions.

In order to develop species-specific allometric equations , the biomass of four species (species pool 1) used by SP5 were measured in parallel with our 15N labelling campaigns (summer and autum 2009, winter and spring 2010). The allometric equati...

Insect herbivores moderate forest functioning under global environmental change, which makes understanding herbivore community dynamics a key challenge of ecological research. Plant-regulated bottom-up effects and climatic conditions determine her...
