Item Data Supporting 'When things don’t add up: quantifying impacts of multiple stressors from individual metabolism to ecosystem processing'(2018-01-11) Galic, Nika; Sullivan, Lauren L; Grimm, Volker; Forbes, Valery E; ngalic@umn.edu; Galic, NikaThese data were produced with an individual-based model of amphipod populations exposed to combinations of hypothetical stressors. Stressors targeted feeding, reproduction, maintenance and growth processes in individual amphipods. We measured body sizes and cumulative reproduction in each individual in the simulation, population abundance and biomass and, finally, amount of unprocessed leaf litter which was consumed by the amphipods. Files contain 20 year time series of those endpoints in different stressor combinations; each combinations was replicated 50 times.Item Individual-Based-Model used in "Population context matters: predicting effects of metabolic stress mediated by food availability and predation with an agent- and energy budget-based model"(2019-08-30) Vaugeois, Maxime; Accolla, Chiara; Venturelli, Paul A; Forbes, Valery E; Hummel, Stephanie L; mvaugeoi@umn.edu; Vaugeois, Maxime; University of Minnesota, EEBThis is the programming software code of the model developed to investigate the population-level impacts of a hypothetical, sublethal stressor that can affect an individual’s metabolism (growth, reproduction, maintenance, or assimilation) in systems in which population size is controlled by different combinations of food availability and predation pressure. The life cycle of fathead minnow (Pimephales promelas) is describe through their metabolism, using the Dynamic Energy Budget theory (DEB) and we represent the populations through an Individual-Based Model (IBM).
