... to that of O. schayeri tested in summer, which was near their estimated thermotolerance limits. The additional costs associated with the elevated metabolism and regeneration rates incurred by the unseasonably warm winter temperatures may lead to increased mortality and predation risk. Summary: High...

... endurance is likely their robust heat shock response (HSR), which contributes to thermotolerance at the cellular level. However, less is known about other mechanisms of thermotolerance, especially those operating at the tissue level. To elucidate other determinants of resilience in this species, we used...

... Thermal sensitivity Heart rate Thermotolerance Thermal safety margin Latitudinal gradients For ectotherms, environmental temperature ( T a ) is perhaps the most important abiotic factor that affects their body temperature ( Hochachka and Somero, 2002 ; Young et al., 2011 ) influencing...

... (with and without a heat pre-treatment) except for males from one set of lines. Several QTL were identified involving all three major chromosomes. Most QTL for larval thermotolerance overlapped with thermotolerance QTL identified in previous studies for adults, indicating that heat-stress resistance...

.... There was a significant interaction between heat hardening and density effects in RIL-D48. Several QTL were significant for both density and hardening treatments. Many QTL overlapped with thermotolerance QTL identified for other traits in previous studies based on LD cultures only. However, three new QTL were found in HD...

... of confounding effects. Although it is important to clearly define experimental methods, particularly when undertaking comparative assessments, and to understand potential confounding effects, thermotolerance assays based on ramping remain an important tool for understanding and predicting species responses...

...Donna G. Folk; Luke A. Hoekstra; George W. Gilchrist SUMMARY To explore the correlation of traits linked to thermotolerance, we compared three thermal endpoints (knockdown temperature and two critical thermal maxima) among replicate populations of Drosophila melanogaster selected for high, or low...

...Corinne I. Rodgers; Kelly L. Shoemaker; R. Meldrum Robertson SUMMARY The mechanisms by which different life histories affect neural circuits are largely unknown. We show that the thermosensitivity and thermotolerance of neural circuit operation are affected in a complex dynamic fashion...

...Donna G. Folk; Patty Zwollo; David M. Rand; George W. Gilchrist SUMMARY We studied adaptive thermotolerance in replicate populations of Drosophila melanogaster artificially selected for high and low knockdown temperature ( T KD ), the upper temperature at which flies can no longer remain upright...

...Toshiaki Sasaki; Yoshimi Konoha; Taichi Toyoda; Yuta Yasaka; Eva Przybos; Yasuo Nakaoka SUMMARY The relationship between thermotolerance and membrane properties was studied by using a ciliated protozoan, Paramecium aurelia . P. aurelia is a complex of sibling species termed `syngens' whose cell...

...Ariel Shabtay; Zeev Arad SUMMARY Living organisms respond to heat exposure by selectively expressing heat shock proteins (HSPs). Accumulation of HSPs confers thermotolerance in cell cultures and in ectotherms and is an important component of the heat shock response. This response, however, has...

... of a prior anoxic stress on the effects of a subsequent high-temperature stress. Anoxic stress and heat shock induced thermotolerance by increasing the ability of intact locusts to survive normally lethal temperatures. To determine whether induced thermotolerance observed in the intact animal was correlated...

... slowly stained most intensely with Trypan Blue. Gut stained especially intensely, which suggests that its sensitivity to heat shock may limit larval thermotolerance. These patterns further suggest that some cells respond primarily to damage caused by heat shock rather than to elevated temperature per se...

...Martin E. Feder; Noemi V. Cartaño; Lukasz Milos; Robert A. Krebs; Susan L. Lindquist ABSTRACT To determine how the accumulation of the major Drosophila melanogaster heat-shock protein, Hsp70, affects inducible thermotolerance in larvae and pupae, we have compared two sister strains generated...

...Rukaya El-Wadawi; Ken Bowler ABSTRACT The LD 50 of 10-day-old adult blowflies was determined to be 38.12±0.07 ˚C. A transitory increase in heat resistance occurred following the exposure of adult blowflies to a sublethal heat shock at 36 ˚C. This thermotolerance was apparent 1 h after...
