Effects Of Thermal Acclimation On The Critical Thermal Maxima Of The Tropical Cockroaches: Blaptica Dubia, Eublaberus Posticus And Blaberus Discoidalis (blaberidae)
<p>The Critical Thermal Maxima (CTMax) is a measure of upper thermal tolerance. The physiological response upon reaching CTMax is similar across taxa, making CTMax useful in comparative studies. The CTMax defines the ecological lethal temperature of an organism and has been used to predict the …

Tolerating climate change: a study on the influence of thermal history on thermal tolerance of Galaxias zebratus in rivers of the Cape Peninsula, South Africa
… tolerance limit or critical thermal maximum (CTmax) of a species. Thermal history is the range of temperatures experienced by an organism in its natural habitat over time and this may be an important factor determining the thermal tolerance of species. The aim of this study was to evaluate the …

The thermal tolerances and preferences of native fishes in the Cape Floristic Region: towards understanding the effect of climate change on native fish species
… upper thermal limits (critical thermal maxima/CTmax) were determined for seven native species of freshwater fish. Thermal preferences were also determined for five of these species using the acute gradient tank approach to elucidate thermal habitat preferences. Species that were identified by …

Effects of chronic, sublethal ferric iron exposure on the critical swim speed of rainbow trout (Oncorhynchus mykiss) and critical thermal maximum of cutthroat trout (Oncorhynchus clarkii)
… of ferric iron. The critical thermal maximum (CTmax) and changes in weight were tested. There were no significant changes in CTmax or weight measured in the second experiment.

The Thermal Performance and Tolerance of Tropical cleaner shrimp (Lysmata amboinensis)
… failure coincided with the upper thermal limit (CTmax = 35.25°C), but it failed to explain the complete collapse of ventilation at critically low limits (CTmin = 7.5°C), and anaerobic metabolism was not exclusive to temperatures near CTmax or CTmin. Chapter Three is a call for collaborative …

The influence of environmental temperature on the thermal tolerance of Antarctic notothenioid fishes
… endemic fishes, the critical thermal maximum (CTMax) was determined in 11 species of Antarctic fishes including six from the HAZ and five from the SPZ. Like freeze avoidance, heat tolerance among the Antarctic fishes could be separated according to their geographic distribution with the CTMaxs …

Behavioural and physiological ecology of the Namib Desert dune ant, Camponotus detritus emery
… ° C at 100 % rh and 31 - 33 ° C at 30 % rh. The CTmax of workers was 53 ° C at 100 % and 30 % rh and CT . was 4,57 ° C at 100 % rh. min Workers tolerated -1 ° C, 95 % rh; 45 ° C, 95 %rh and 45 ° C, 45 % rh for 24 hours. Water loss increased with increasing saturation deficit at 35 ° C but was …

The influence of spatiotemporal variation in ambient temperature on the ecology and physiology of birds
… Ta above the UCT) and critical thermal maximum (CTmax – the Ta at which birds become hyperthermic and lose the ability to regulate Tb)] that comprise heat tolerance. Contrary to previous studies of ectotherms, I found limited evidence of reduced heat tolerances in tropical species. In …

Understanding the thermal biology of macadamia nut borer, Thaumato(bia batrachopa (Meyrick) (Lepidoptera: Tortricidae): a pest of macadamia in South Africa
… minimum (CTmin) and criScal thermal maximum (CTmax) than adults across all acclimaSon temperatures. Instar 4 larvae were the most heat and cold-tolerant aier acclimaSon across all temperatures. Pre-exposure and exposure for two hours didn’t significantly improve each life stage's survival. …

Hypoxia and thermal tolerance in New Zealand triplefin fishes
… (21-29°C) and the upper thermal tolerance limit (CTmax) of two intertidal triplefin fishes (B. medius and Forsterygion lapillum) under hyperoxia and normoxia. Hyperoxia increased ṀO₂,max and MS of each species at ambient temperature (21°C) and also after thermal ramping to elevated temperatures …

The responses of subtropical nearshore fishes to climate change
… To do this, the critical thermal maximum (CTMax) and minimum (CTMin) of adult bonefish, adult checkered puffer, juvenile yellowfin mojarra, and juvenile schoolmaster snapper were determined across seasons. Acclimatization response ratios (AZRR; ΔCTMax ΔT-1 and ΔCTMin ΔT-1) were typically …
