This data release contains the two intermediary variables (processed lake temperature prediction feather files and bioenergetic metrics CSV), model code in R script used to produce the outputs, and bioenergetics model prediction feather files for a set of fish bioenergetics models under current and future temperature conditions at 337 large lakes.
Threats to the future function of forested ecosystems and stability of ecosystem service provisioning due to global change have motivated climate-adaptive forest management strategies that include various forms of tree planting termed “adaptation plantings”. Despite the emergence of these strategies, less is known as to how foresters and other natural resource managers perceive or are engaged with adaptation plantings like forest assisted migration (FAM). This knowledge gap is most pronounced in regions like New England and the North Central US (hereafter, the Northeastern US) where tree planting is less common but expected to be an important forest management tool for adaptation. To address this, we surveyed 33...

Objective The objective of this study was to evaluate stocking success of Walleye Sander vitreus in lakes and reservoirs across the Midwestern United States to inform stocking practices for state agencies. Demand for Walleye stocking may increase if climate change limits the potential for natural recruitment in lakes. Consequently, the strategic distribution of Walleye stocking may maximize fishing opportunities. Methods We synthesized data from 2226 Walleye fry and fingerling stocking events on 653 lakes in the Midwestern United States and used random forest algorithms and mixed‐effects linear models to identify abiotic and biotic factors related to Walleye stocking success. Result Latitude and year explained...

Traditional conservation efforts have centred on safeguarding individual species, but these strategies have limitations in a world where entire ecosystems are rapidly changing. Ecosystem conservation can maintain critical ecological functions, but often lacks the detail necessary for the effective conservation of threatened or endangered species. The conservation of such species is mandated by policies and remains a dominant focus of natural resource management. In this Perspective, we propose that assemblage-level conservation targeting groups of taxonomically related or functionally similar species can bridge the gap between species and ecosystems and help to address global biodiversity loss. This approach has...

Climate change is altering the thermal habitats of freshwater fish species. We analyze modeled daily temperature profiles from 12,688 lakes in the US to track changes in thermal habitat of 60 lake fish species from different thermal guilds during 1980-2021. We quantify changes in each species’ preferred days, defined as the number of days per year when a lake contains the species’ preferred temperature. We find that cooler-water species are losing preferred days more rapidly than warmer-water species are gaining them. This asymmetric impact cannot be attributed to differences in geographic distribution among species; instead, it is linked to the seasonal dynamics of lake temperatures and increased thermal homogenization...

This data release contains a CSV dataset of the likelihood of sapling recruitment based on abundance of seedlings height classes and other stand and site-level factors. Maps accompany the CSV on how the relationship between temperature and relative survival and seedling/sapling abundance varies by size class for ten tree species in the northeastern and midwestern USA, and can be used to highlight areas where survival prospects are relatively better or worse for seedlings of different sizes.
This is an update to a previously archived data set, which is available at https://doi.org/10.13020/4zwr-t415. Here, additional sites for 2021, and additional data for 2022 and 2023 are given. There will be no further updates. 570 station occupations occurred along Lake Superior’s southwest shoreline where data were collected from Lake Superior and its watershed in the region generally between Duluth-Superior and Ashland, WI. Parameters include forms of carbon, nitrogen, and phosphorus, along with total suspended solids, chlorophyll, and phycocyanin.

Waterfowl are of substantial economic and cultural importance, with over 1 million hunters contributing approximately $700 million in total expenditures to local and regional economies annually. However, shifts or expansions in waterfowl distribution driven by the interacting effects of a warming climate, changes in habitat resources, and altered anthropogenic pressures will present challenges to effective management and conservation. Understanding historical changes in waterfowl distributions and the associated drivers of these changes would improve the ability of natural resource managers to anticipate future changes and develop more adaptive conservation and management approaches for potential shifts in waterfowl...
