Life spans were found to be temperature dependent at constant temperatures of 22, 27, and 32°C, but they were divided into 'ageing' and 'dying' phases at split-temperatures. The rate of ageing, which was independent of temperatures, was the same in males whether they were transferred from...
Control pupae were held at a constant temperature of 25 °C until emergence. The pupae in the FTR treatment were incubated for up to 8 weeks. Each week, a subset (n = 36) of FTR pupae was removed from FTR and placed at 25 °C until emergence to determine mortality. No adults ...
We compared responses of adults and larvae of the brooding corals Pocillopora damicornis and Seriatopora hystrix to 12-h exposures to constant temperature treatments (21掳C, 28掳C, or 30掳C) and a treatment in which temperature fluctuated from 28掳 to 21掳C, simulating daily temperature ...
The impact of daily temperature fluctuations on arthropod life history parameters is inadequately studied compared with the ample amount of research that has been conducted on the effects of constant temperatures. Fluctuating temperatures are likely to be more realistic, as they are ecologically more ...
Life table statistics varied among temperature regimes when time was expressed in days, but converged when time was expressed in degree-days (DD). Stable instar distributions varied on a DD scale. The proportion of immatures increased and the proportion of adults decreased with increasing temperature...
Under an FTR of 11°C (22h)/20°C (2h) (average 11.8°C) survival of females drastically increased compared to that at a constant temperature of 12°C, whereas the survival of males increased slightly. Survival under FTRs indicates that adult B. latifrons may not overwinter in the north...
melanogaster versus a constant temperature of 6 and 22 °C. We demonstrate that FTR increases mean longevity by 8.8‐fold compared to a constant 6 °C and by 5.9‐fold to a constant 22 °C. We assessed male and female fertility of FTR treated adults from 20 to 100 days at 20 day ...
Most studies of temperature effect address constant thermal regime (CTR), whereas organisms are exposed to fluctuating thermal regime (FTR) in their natural environ- ments. In addition, previous works have predominantly addressed issues of thermal tolerance in adults rather than in early life stages....
(pupac and adults).Generally,FTR improved cold storage tolerance with respect to constant low temperatures(CLT).Cold mortality was lower when recovery temperature was 20鈩 or higher,when duration was 2 h per day or longer,and when warming interruptions occurred frequently(every 12 or 24 h)....
We found no significant differences between the treatments in juvenile growth rate or juvenile survival. Also, adults that had grown up under high frequency temperature fluctuations did not suffer from reduced starvation resistance compared to animals growing under low frequency temperature fluctuations. ...
