The physiological arms race: Exploring thermal acclimation among interacting species
چکیده انگلیسی

Thermal acclimation is often expected to increase performance during survival-related interactions, such as prey-capture and predator escape. However, few studies have examined acclimation responses in the context of the organism's ecology: namely, considering interactions among different species. In this study, we investigated the acclimation responses of three species of aquatic organisms from the same environment that simultaneously interact across different seasons. We predicted that the crimson spotted rainbowfish (Melanotaenia duboulayi) and the freshwater shrimp (Paratya australiensis), which are involved in a predator–prey relationship, would exhibit similar thermal acclimation responses due to an arms race in physiological responses. In contrast, we expected that the backswimmer (Enithares sp.) species from the same environment, which is not commonly preyed upon due to their hard chitinous exterior, would display a limited acclimation response. We found that acute increases in temperature resulted in improved locomotor performance for all three species and an improved prey capture performance for M. duboulayi. Acclimation to 15 °C or 25 °C for 6 weeks did not affect the prey-capture performance of M. duboulayi or the locomotor performance of either M. duboulayi or Enithares sp. However, acclimation to cool temperatures improved the locomotor performance of P. australiensis at both cool and warm temperatures. Thus, the interaction between M. duboulayi (predator) and P. australiensis (prey) is likely to change across seasons via differences in acclimation responses, which could directly affect their behavioural strategies and population dynamics.
