File List: Data_Predators override rainfall effects on tropical food webs.csv, An experiment with an invertebrate food web module from tank bromeliads, we manipulated the presence of an odonate predator under scenarios of 10-fold decreased, ambient, and 3-fold increased precipitation and measured responses of prey and their basal resource (abundance and stoichiometry). 2. Relationship between files, if important: 3. Additional related data collected that was not included in the current data package: 4. Are there multiple versions of the dataset? No A. If yes, name of file(s) that was updated: i. Why was the file updated? ii. When was the file updated? METHODOLOGICAL INFORMATION 1. Description of methods used for collection/generation of data: Materials and methods section of paper "Predators override rainfall effects on tropical food webs" Biotropica. 2. Methods for processing the data: Ww calculated the water depth mean, coefficient of variation, using the measure of water depth.We also calculated the mean, median, standard deviation, and coefficient of variation of water temperature. All insects at the end of the experiment were allowed to evacuate their guts, cleaned, dried at 60 °C for 72 h, and ground with mortar and pestle in preparation for determinations of isotopic and elemental composition. Isotopic analysis and %C and %N were done in the Cornell University Stable Isotope Laboratory (COIL) using a Finnigan MAT Delta V isotope ratio mass spectrometer interfaced with a Carlo Erba NC2500 elemental through a Conflo III open split interface for isotopic and elemental composition of solid samples. 3.
