Vegetation foraging ants feed to a considerable part on liquid plant exudates or on Hemipteran honeydew. Those liquids contain mainly sugars and amino acids (AA), which are attractive for the ants. We conducted a choice experiment using different ...

This data documents the tree growth parameters for seven years from 2010 to 2016 for site A of the main experiment. Measurements for this data took place at the end of the growing season of deciduous trees, mainly in September and October of each ...

Soil chemical laboratory analyses of all 27 comparative study plots. Contents of carbon, nitrogen and sulphur as well as pH-values (H2O and KCl) of six depth increments per CSP. Total depth is 50 cm.

This is the 2008 CSP PLFA data from a subset of 12 CSPs representing the age gradient. Samples were analyzed over the depth profile of each CSP (see detailed methods below) and analyzed for phospholipid fatty acid profiles, which represent both th...

This data documents the tree growth parameters in 2011 for site B, belonging to the annual inventory taking place for both site A and site B. Individual-tree growth is a function of stand attributes, local neighbors, plant size, plant damage, geno...

Individual-tree growth is a function of stand attributes, local neighbors, plant size, plant damage, genotype, and local abiotic site conditions. Given a certain time phase (combing further data along the timeline), the following scientific questi...
