“…Previous studies with other terrestrial and marine predator-prey systems have shown contrasting results with prey presenting either higher or lower CT max than their predators (Cheng et al, 2017;Coombs & Bale, 2014;Franken et al, 2018;Hughes et al, 2010;de Mira-Mendes et al, 2019;Monaco et al, 2016;Stoks et al, 2017).…”

“…Although our approach has provided, to our knowledge, the most extensive analyses of thermal tolerances within a predator–prey system, we cannot rule out the possibility that the relationship between predatory thermal margins and environmental thermal variability could arise if more field sites are included. Previous studies with other terrestrial and marine predator–prey systems have shown contrasting results with prey presenting either higher or lower CT max than their predators (Cheng et al., 2017; Coombs & Bale, 2014; Franken et al., 2018; Hughes et al., 2010; de Mira‐Mendes et al., 2019; Monaco et al., 2016; Stoks et al., 2017). Those differences may be idiosyncratic and related to specific predation and evasion mechanisms within each system and therefore should be analysed independently.…”

“…de Mira‐Mendes et al. (2019) showed that invertebrate predators, which possess higher thermal tolerance than their tadpole prey, increase their predation rate at higher temperatures. Additionally, damselflies increase food intake and ultimately growth rate with heat waves (Van Dievel et al., 2017).…”

Climate change may have dramatic consequences for communities through both direct effects of peak temperatures upon individual species and through interspecific mismatches in thermal sensitivities of interacting organisms which mediate changes in interspecific interactions (i.e. predation). Despite this, there is a paucity of information on the patterns of spatial physiological sensitivity of interacting species (at both landscape and local scales) which could ultimately influence geographical variation in the effects of climate change on community processes. In order to assess where these impacts may occur, we first need to evaluate the spatial heterogeneity in the degree of mismatch in thermal tolerances between interacting organisms. We quantify the magnitude of interspecific mismatch in maximum (CTmax) and minimum (CTmin) thermal tolerances among a predator–prey system of dragonfly and anuran larvae in tropical montane (242–3,631 m) and habitat (ponds and streams) gradients. To compare thermal mismatches between predator and prey, we coined the parameters maximum and minimum predatory tolerance margins (PTMmax and PTMmin), or difference in CTmax and CTmin of interacting organisms sampled across elevational and habitat gradients. Our analyses revealed that: (a) predators exhibit higher heat tolerances than prey (~4°C), a trend which remained stable across habitats and elevations. In contrast, we found no differences in minimum thermal tolerances between these groups. (b) Maximum and minimum thermal tolerances of both predators and prey decreased with elevation, but only maximum thermal tolerance varied across habitats, with pond species exhibiting higher heat tolerance than stream species. (c) Pond‐dwelling organisms from low elevations (0–1,500 m a.s.l.) may be more susceptible to direct effects of warming than their highland counterparts because their maximum thermal tolerances are only slightly higher than their exposed maximum environmental temperatures. The greater relative thermal tolerance of dragonfly naiad predators may further increase the vulnerability of lowland tadpoles to warming due to potentially enhanced indirect effects of higher predation rates by more heat‐tolerant dragonfly predators. However, further experimental work is required to establish the individual and population‐level consequences of this thermal tolerance mismatch upon biotic interactions such as predator–prey.

“…Third, our proposed hypothesis helps to explain why size-specific metabolic responses to fish cues are temperature dependent. This may occur because olfaction of fish cues is stronger at higher temperatures and (or) because predator-prey encounters tend to become more frequent as temperature increases [1,25,[28][29][30]53,54]. As expected, fish cues have little effect on metabolic scaling at low temperatures, but at high temperatures, the presence of fish cues causes small amphipods to increase their metabolic rate more than that of large amphipods, which show little change, thus decreasing the scaling exponent.…”

Temperature and predator cues interactively affect ontogenetic metabolic scaling of aquatic amphipods

A common belief is that body mass scaling of metabolic rate results chiefly from intrinsic body-design constraints. However, several studies have shown that multiple ecological factors affect metabolic scaling. The mechanistic basis of these effects is largely unknown. Here, we explore whether abiotic and biotic environmental factors have interactive effects on metabolic scaling. To address this question, we studied the simultaneous effects of temperature and predator cues on the ontogenetic metabolic scaling of amphipod crustaceans inhabiting two different aquatic ecosystems, a freshwater spring and a saltwater lagoon. We assessed effects of phenotypic plasticity on metabolic scaling by exposing amphipods in the laboratory to water with and without fish cues at multiple temperatures. Temperature interacts significantly with predator cues to affect metabolic scaling. Our results suggest that metabolic scaling is highly malleable in response to short-term acclimation. The interactive effects of temperature and predators show the importance of studying effects of global warming in realistic ecological contexts.

“…Climate change is composed of different processes and phenomena (IPCC, 2013 ), including extreme weather events such as heavy precipitations or heatwaves (HWs; Jentsch et al, 2007 ). HWs are characterized by a short‐term, rapid increase in temperature, which can impact all trophic levels, from microorganisms (Szymczak et al, 2020 ) to large predators (de Mira‐Mendes et al, 2019 ), across all ecosystem types (Stillman, 2019 ). HWs are of particular concern because their magnitude and frequency are predicted to increase in the future (Meehl & Tebaldi, 2004 ; Woolway et al, 2021 ).…”

Freshwater ecosystems are strongly influenced by weather extremes such as heatwaves (HWs), which are predicted to increase in frequency and magnitude in the future. In addition to these climate extremes, the freshwater realm is impacted by the exposure to various classes of chemicals emitted by anthropogenic activities. Currently, there is limited knowledge on how the combined exposure to HWs and chemicals affects the structure and functioning of freshwater ecosystems. Here, we review the available literature describing the single and combined effects of HWs and chemicals on different levels of biological organization, to obtain a holistic view of their potential interactive effects. We only found a few studies (13 out of the 61 studies included in this review) that investigated the biological effects of HWs in combination with chemical pollution. The reported interactive effects of HWs and chemicals varied largely not only within the different trophic levels but also depending on the studied endpoints for populations or individuals. Hence, owing also to the little number of studies available, no consistent interactive effects could be highlighted at any level of biological organization. Moreover, we found an imbalance towards single species and population experiments, with only five studies using a multitrophic approach. This results in a knowledge gap for relevant community and ecosystem level endpoints, which prevents the exploration of important indirect effects that can compromise food web stability. Moreover, this knowledge gap impairs the validity of chemical risk assessments and our ability to protect ecosystems. Finally, we highlight the urgency of integrating extreme events into multiple stressors studies and provide specific recommendations to guide further experimental research in this regard.
