Description
Summary:1. Ecosystems at high latitudes are exposed to some of the highest rates of climate warming on earth, and freshwater ecosystems in those regions are already experiencing extended ice-free seasons and warmer waters. The dominant fish species in these ecosystems are cold-water salmonids, which play a central ecological role in lake ecosystems, where they are often exposed to size-selective fisheries that truncate their size- and age-distributions, making them potentially vulnerable to exploitation and environmental perturbations. 2. Here, we address the combined effects of climate-induced water-temperature increase (using regionally downscaled climate models based on RCP-4.5 and RCP-8.5 together with an air-to-water temperature model) and gillnet harvesting, over the period from 1950 to 2100, on the somatic growth, demography, and vulnerability of Arctic charr Salvelinus alpinus (L.), using an eco-genetic individual-based model. The model captures successive annual life-history events, including the key ... : Individual Based Model Output Output from an eco-genetic Individual Based Model parameterised for Arctic charr from Lake Takvatn. ...
