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,...
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...
