“…We also found another behavioural syndrome, where the latency to respond with immobility was negatively correlated with the total duration of immobility. Overall, our results support the fact that RMR may be positively related to mortality, as recently found in land snails, juvenile squirrels, captive voles, and mealworm beetles (Alvarez & Nicieza, ; Smith & Blumstein, ; Artacho & Nespolo, ; Boratynski & Koteja, ; Larivee et al., ; Lantová et al., Krams et al., ). Repeatabilities for our four main measures (RMR, hiding behaviour, latency to become immobile, and total time spent immobile) were all statistically significant and ranged from 0.613 (latency to respond after flicking of the plastic container) to 0.926 (RMR).…”

The energetic definition of fitness predicts that natural selection will maximize the residual energy available for growth and reproduction suggesting that energy metabolism might be a target of selection. In this experimental study, we investigated whether female and male yellow mealworm beetles, Tenebrio molitor L. (Coleoptera: Tenebrionidae), differ in their hiding behaviour, individual response latency time, and duration of immobility to treatments mimicking an approaching predation threat. We experimentally tested whether consistently repeatable anti‐predatory responses and resting metabolic rates (RMR) correlated with survival rates of individuals exposed to a nocturnal predator, the brown rat, Rattus norvegicus (Berkenhout) (Rodentia: Muridae). Resting metabolic rate was part of a syndrome involving anti‐predator behaviour. Individuals with lower RMR concealed themselves against predators in substrate more successfully than individuals with higher RMR, and hiding was associated with longer periods of immobility. Ultimately, mortality was higher in the high‐RMR beetles compared to the low‐RMR beetles. Our results provide direct evidence of natural selection against mobility, i.e., for reduced RMR in T. molitor beetles.

“…These shifts in energy acquisition and allocation can directly impact individuals' reproductive abilities and survival (Magnhagen, 1991;Preisser et al, 2005). Trade-offs between reproductive investment and predation risk and between starvation and predation risk are thus central to many decisions individual prey make regarding habitat choice, foraging and mating (Krams et al, 2013), ultimately leading to predation risk being key to our understanding of how predators shape the life histories of prey.…”

“…However, often predators have a preference for larger individuals, and tadpoles of Rana sylvatica are smaller in the presence of predators . Predation can therefore act as a directional selection pressure that produces particular prey phenotypes, such as smaller size , lower metabolic rates (Handelsman et al, 2013;Krams et al, 2013) and greater locomotor performance (Watkins, 1996). All of these traits that respond to predation pressure are also sensitive to changes in temperature (Traill et al, 2010).…”

Environmental conditions during embryonic development can influence the mean expression of phenotypes as well as phenotypic responses to environmental change later in life. The resulting phenotypes may be better matched to their environment and more resilient to environmental change, including human-induced climate change. However, whether plasticity does improve success in an ecological context is unresolved. In a microcosm experiment, we show that developmental plasticity in embryos of the frog Limnodynastes peronii is beneficial by increasing survivorship of tadpoles in the presence of predators when egg incubation (15 or 25°C) and tadpole acclimation temperature in microcosms (15 or 25°C) coincided at 15°C. Tadpoles that survived predation were smaller, and had faster burst swimming speeds than those kept in no-predator control conditions, but only at high (25°C) egg incubation or subsequent microcosm temperatures. Metabolic rates were determined by a three-way interaction between incubation and microcosm temperatures and predation; maximal glycolytic and mitochondrial metabolic capacities (enzyme activities) were lower in survivors from predation compared with controls, particularly when eggs were incubated at 25°C. We show that thermal conditions experienced during early development are ecologically relevant by modulating survivorship from predation. Importantly, developmental thermal plasticity also impacts population phenotypes indirectly by modifying species interactions and the selection pressure imposed by predation.
