A mosaic of induced and non-induced branches promotes variation in leaf traits, predation, and insect herbivore assemblages in canopy trees

Branch_variables.xlsx
Variables measured during for individual branches we studied. Each branch is characterized by Tree number and Branch number within the respective tree. The measured variables include leaf area (m2), induction treatment we applied (treatment/control), their height above ground (m), VOC emission level (Total area under the peaks of all VOCs we measured with GC-MS), VOC composition (similarity in VOC profiles emitted by the studied branches as measured on the first PCA axis), Leaf toughness (N), content of HHDPs (mg/g), content of total phenolics (mg/g), predation rates (0.00-1.00), herbivore preference (average area of leaf discs eaten (in mm) by Lymantria dispar in food-choice trials), herbivore abundance (number of caterpillars and sawfly larvae sampled from the given branch standardized by its leaf area), herbivore richness (species richness of caterpillars and sawfly larvae sampled from the given branch).

VOCs.xlsx
VOCs detected in our samples. Values show means ± st.dev. for control (C) and treated beaches (T) on individual trees. The reported values represent total areas under the peaks as measured with GC-MS.

Insects.xlsx
Leaf-chewing larvae sampled from treated and control branches on the studied trees. In total, we sampled 898 sawfly larvae and caterpillars. Four larvae with incomplete information on the host tree or branch were excluded from all analyses and are not shown in the data. The data on COI sequences used for insect identification including the standard fields for the BARCODE data standard are available on BOLD (www.boldsystems.org, dx.doi.org/10.5883/DS-LAK2019). Each species is characterized by its Order, Family, Species name, and Species code and the table shows the total number of individuals sampled from control (C) and treated (T) branches in the studied trees.
