Anthropogenic change decouples a freshwater predator’s density feedback

The datasets here were used to determine annual changes in anthropogenic
environmental stressors, the prey-fish community, and the walleye
population in Lake Erie and its western basin during 1969–2018. Here, we
provide three datasets, which are used in the paper by Sinclair et al.
titled: "Anthropogenic change decouples a freshwater predator’s
density feedback". Each dataset is provided as a separate tab in a
single Excel worksheet. The first dataset ("Environmental
stressors") provides the annual values for nutrient inputs, water
transparency, temperature, and commercial walleye harvest. The second
dataset ("Prey-fish community") provides the annual
catch-per-unit-effort (CPUE; individuals per trawl minute) for all fish
species that tend to be found in walleye diets caught in Lake Erie's
western basin during 1969–2018 in fall (September-October) trawl surveys
conducted by the Ohio Department of Natural Resources - Division of
Wildlife. The third dataset ("Walleye") provides the annual
estimated size of the age-3+ walleye population, the number of walleye
growing degree days, and the average lengths of age-1 and age-2 walleye
caught in gill net surveys conducted in the western basin by the Ohio
Department of Natural Resources - Division of Wildlife. A summary and
explanation of each variable are also provided in the "Info"
tab. Further information on how values were calculated is provided in the
methods and supporting information of the associated article.
