“…As the sheepshead minnow, Cyprinodon variegatus, is acclimated to temperatures from 5°C to 40°C, its CTmax increases; concomitantly, its CTmin increases, so that the overall thermal range of activity remains more or less constant (Beitinger et al, 2000). In addition, Layne et al (1987) found that crayfish acclimated to 5°C had lower CTmin and CTmax than crayfish acclimated to 25°C. However, the data of Klok and Chown (2003) indicate that CTmin and CTmax are decoupled in several species of weevils.…”

SUMMARY The primary objectives of this study were to determine (1) whether rapid cold-hardening (RCH) preserves reproductive behaviors during modest cooling,(2) whether increased mating success at a lower temperature comes at the cost of decreased performance at a higher temperature and (3) whether RCH is associated with an elevated metabolic rate. Drosophila melanogaster(Diptera: Drosphilidae) were rapidly cold-hardened by a 2-h exposure to 16°C prior to experiments. A temperature decrease of only 7°C(23°C to 16°C) prevented half (11/22) of the control pairs of D. melanogaster from engaging in any courtship activity. By contrast, most RCH pairs courted (17/20). Additionally, the 7°C transfer prevented mating in every pair of control flies, whereas more than half (11/20) of the RCH pairs mated. There was no evidence of impaired courtship or mating performance when RCH pairs were tested at 23°C. Finally, RCH is apparently not an energy-demanding process because no increase in the metabolic rate was detected during its induction. Overall, these data demonstrate that RCH serves to constantly fine-tune an insect's physiological state to match slight changes in environmental temperature. Furthermore, the RCH response is not restricted to cryoprotection and survival in the cold but also preserves more subtle behaviors, such as courtship, at moderate to high temperatures throughout the year.

“…They also found that LT 50 values declined with exposure time. Similar laboratory studies have been performed for freshwater snails in New Zealand (Winterbourn 1969) and for northern hemisphere species of caddisflies (Moulton et al 1993), bivalve molluscs (Read & Cumming 1967), crayfish (Layne et al 1987), dragonfly nymphs (Martin & Gentry 1974), and amphipods (Buchanan et al 1988).…”

For two key New Zealand freshwater invertebrates (the mayfly Deleatidium autumnale and the snail Potamopyrgus antipodarum) the upper thermal tolerances were measured in the laboratory under both constant and diumally varying temperatures. At constant temperature 50% mortality in 96 h ( const LT 50 ) occurred at 24.2 ± 0.9°C for mayflies and 31.0 ± 0.6°C for snails: values similar to previously published estimates (Quinn et al. 1994). For diurnally varying temperatures (daily amplitude 10°C) 50% mortality occurred when the daily mean temperature was 21.9 ± 0.7°C (mayflies) and 28.6 ± 0.4°C (snails) which is c. 10% (2.5 ± 1.3°C) lower than the const LT 50 . Conversely, 50% mortality occurred when the daily maximum temperature was 26.9 ± 0.7°C (mayflies) and 33.6 ± 0.4°C (snails) which is c. 10% (2.5 ± 1.3°C) higher than the const LT 50 . Many published temperature limits for stream organisms are derived from constant temperature experiments. Our results indicate that such limits should be applied to a temperature midway between the daily average and the daily maximum of a diurnal profile.

“…The mayfly nymph, Deleatidium sp., was the most sensitive of the animals tested, with 50% mortality after 96 h occurring at 22.6 ± 0.8°C (mean ± 95% confidence interval), whereas the snail Potamopyrgus antipodarum was the least sensitive (32.4 ± 2.5°C). Similar studies have been performed for a variety of other aquatic invertebrate species (e.g., see Read & Cumming 1967;Winterbourn 1969;Martin & Gentry 1974;Buchanan et al 1987;Layne et al 1987;Moulton 1993). These studies provide good insights into the relative temperature tolerances of species but the results cannot easily be applied to natural streams because the experiments were conducted at either constant or linearly increasing temperatures.…”

“…This suggestion is supported by the observation that Deleatidium collected in summer and acclimated at 21-22°C had a significantly lower mortality than Deleatidium also collected in summer but acclimated at 16-17°C when exposed to 25 ± 2.5°C. Acclimation in stream macroinvertebrates is generally well documented (Sweeney 1978;Layne et al 1987;Buchanan et al 1988) although it has not been quantified for the majority of New Zealand stream invertebrates (Quinn et al 1994). …”

Predicting the effects of time‐varying temperatures on stream invertebrate mortality

Stream managers often need to predict the impacts of high and time-varying temperature on key stream invertebrates. A simplified model has been developed and calibrated using mortality observations made at constant temperature for two important New Zealand stream invertebrates: the snail Potamopyrgus antipodarum and the mayfly Deleatidium autumnale. A close fit was obtained for Deleatidium but Potamopyrgus showed evidence of acclimation during the 96-h tests. The model successfully predicted the mortality observed when temperature varied diurnally by ±5°C in seven experiments but over-estimated mortality in the eighth. The experiments used to calibrate and test the model were performed on test animals collected in winter (April-June) and acclimated at 16-17°C. The model was less successful at predicting mortality on Deleatidium collected in summer (December-January) and/or acclimated at 21-22°C. The likely reason is that the model, calibrated using winter data, does not account for summer acclimation.
