In many ectotherms, exposure to high temperatures can improve subsequent tolerance to higher temperatures. However, the differential effects of single, repeated or continuous exposure to high temperatures are less clear. We measured the effects of single heat shocks and of diurnally fluctuating or constant rearing temperatures on the critical thermal maximum (CTmax) for final instar larvae of M...

In this study, we review federal datasets to assess the impacts of once-through power plant cooling systems on summer freshwater temperatures in the United States from 1996 to 2005. We find that maximum reported temperature discharges averaged 37 C (1996–2005) and were 9.5 C (1996–2000) to 10 C (2001–2005) higher than maximum reported intake temperatures during the summer. More than half of all...

bstract: Air and surface freezing and thawing indexes and prediction of round temperatures from air temperatures were investigated. A new method for pplying n factors on a daily basis to capture localized temperature extremes is resented and compared to conventional seasonal n-factor analysis. Measured air emperatures from five locations and measured air and surface temperatures from ne locatio...

Distribution patterns of stress-tolerant coral symbionts suggest that maximum habitat temperatures can drive local scale adaptation of symbiont populations, but at regional scales other processes can dominate. We assayed clade membership for symbionts of 2 closely related corals from American Samoa, Fiji, the Philippines and Palmyra Atoll. Temperature stress-tolerant Clade D symbionts occur mor...

Little information is available on the growth and activity of bacteria at temperatures above the optimum, despite the fact that in many commercial processes the organisms used are often subject to temperatures higher than those most favorable for growth. In the manufacture of Swiss cheese, for example, starter cultures must not only survive the high temperatures used during cooking of the curd,...
