Abstract (from http://www.esajournals.org/doi/abs/10.1890/11-2296.1): Physiological tolerance of environmental conditions can influence species-level responses to climate change. Here, we used species-specific thermal tolerances to predict the community responses of ant species to experimental forest-floor warming at the northern and southern boundaries of temperate hardwood forests in eastern North America. We then compared the predictive ability of thermal tolerance vs. correlative species distribution models (SDMs) which are popular forecasting tools for modeling the effects of climate change. Thermal tolerances predicted the responses of 19 ant species to experimental climate warming at the southern site,...

Climate change is a global phenomenon, but natural selection occurs within landscapes. Many global analyses predict how climate change will shape behavior and physiology, but few incorporate information from the landscape scales at which animals actually respond to selective pressure. We compared cold-water fish (redband trout Oncorhynchus mykiss newberrii) from neighboring habitats in a naturally warm, recently fragmented basin to understand how different responses to warming may arise from landscape constraints. Trout in warm, hydrologically connected Upper Klamath Lake fled summer temperatures and sought refuge in cool tributaries, while trout in an equally warm but fragmented reach of the Klamath River endured...

These data include aerobic scope and thermal tolerance measurements from two cisco (Coregonus artedi) populations to evaluate performance and potential adaptation to warming Great Lakes habitats. Cisco come from two stock sources: 1) a northern latitude Lake Huron stock collected as gametes from Les Cheneaux Islands, MI, USA in 2015 and raised in a USGS aquaculture lab in Ann Arbor, MI, and 2) a southern latitude stock from Crooked Lake, Noble County, IN, USA collected as adults from the wild in 2021 and 2022 and brought to Ann Arbor, MI. Data include three primary datasets. "Aerobic Scope Compiled Data" provides measures of cisco (Coregonus artedi) metabolic rates from 30L swim chamber respirometry trials (n=88)....
Abstract: Native freshwater mussels are long-lived, sessile, benthic invertebrates that may be extremely susceptible to elevated water temperatures because of their patchy distribution, limited dispersal and mobility, and larval dependence on fish. Recent research suggests that many species may be living close to their upper thermal limits and that some rivers have seen a shift in species composition to more thermally tolerant mussel species. We tested the hypothesis that elevated water temperatures (20, 25, 30, and 35°C) adversely affected the survival and physiology of juvenile mussels and physiology of adult mussels. In juveniles, the 28-d LT50s ranged from 25.3 to 30.3°C. H eart rate was significantly affected...
