Perfluorooctanesulfonic acid (PFOS) is an environmental contaminant with a long half-life in animals. Risk assessment of PFOS in livestock and food tissue can be conducted with physiologically-based kinetic (PBK) models. For fast-growing livestock, changes in body weight affect the kinetics of PFOS primarily through tissue dilution, which needs to be considered when using a PBK model. A generic PBK model was used to predict ti...

The potential for forecasting the dynamics of ecological systems is currently unclear, with contrasting opinions regarding its feasibility due to ecological complexity. To investigate forecast skill within and across systems, we monitored a microbial system exposed to either constant or fluctuating temperatures in a 5‐month‐long laboratory experiment. We tested how forecasting of species abundances depends on the number and st...
