“…To minimize this problem, we carefully designed the temperature gradient to ensure that the temperature extremes were not too far away from the in situ temperature (see 'Materials and methods'). Although the thermal shock effect cannot be eliminated completely, our estimates of activation energy for grazing and respiration rates are generally within the normal ranges of literature reports (Dell et al 2011, Fussmann et al 2014, suggesting that the problem of thermal shock was not severe. The third problem is that the design of abrupt changes of temperature in our experiments cannot address the effect of temperature at evolutionary time scales.…”

“…Although often treated as a constant in models, the activation energies can vary significantly with species and environment, confirmed by the significant random effects in the mixed-effect models (Dell et al 2011, Huey & Kingsolver 2011, Fussmann et al 2014. Together with other thermal traits such as optimal temperature (Thomas et al 2012), these overlooked parameters likely play important roles in affecting the response of plankton dynamics and ecosystem properties to warming.…”

“…It is vital to reliably quantify the temperature sensitivity of these key ecological fluxes to evaluate the effects of global warming to our ecosystem (Vasseur & McCann 2005, Fussmann et al 2014. The temperature sensitivity of photosynthesis has been claimed to be lower than that of heterotrophic processes such as respiration and grazing rates (López-Urrutia et al 2006, Rose & Caron 2007, Regaudie-De-Gioux & Duarte 2012.…”

“…Conversely, estimates of temperature sensitivity for the same taxa/ assemblages should be more appropriate for local scales. Significant heterogeneity exists among activation energies, which may vary with functional groups and different ecological processes (Dell et al 2011, Huey & Kingsolver 2011, Fussmann et al 2014.…”

We investigated the responses of plankton collected throughout a seasonal cycle from a eutrophic, subtropical coastal site near Xiamen, China to short-term temperature modulations from the in situ ambient temperature. We used linear mixed effect models to estimate the temperature coefficients (i.e. activation energy) and tested the hypothesis that the activation energies of autotrophic rates (i.e. phytoplankton growth and photosynthesis) are lower than those of heterotrophic rates (i.e. microzooplankton grazing and community respiration). However, we found that there were no significant differences of activation energy (~0.65 eV) between autotrophic and heterotrophic rates. Based on both physiological and statistical grounds, we argue that the inherent activation energies of phytoplankton photosynthesis and growth rates may not be lower than 0.65 eV in some instances.KEY WORDS: Temperature · Phytoplankton · Growth · Grazing · Activation energy · Photosynthesis · Respiration Resale or republication not permitted without written consent of the publisher Editorial responsibility: Graham Savidge,

“…These interactions form the foundation of many emergent aspects of community structure and function. As a result, any change to consumer-resource interaction strengths can induce changes in ecosystem function (O'Connor et al 2011, Fussmann et al 2014, and there is a pressing need to predict how rapid climate change alters fundamental consumer-resource interactions and population dynamics. Strong species interactions often destabilize food webs unless counterbalanced by numerous weak interactions (McCann et al 1998).…”

Citation: Lemoine, N. P. 2019. Considering the effects of temperature 9 nutrient interactions on the thermal response curve of carrying capacity. Ecology 100(4):Abstract. Climate warming will likely destabilize populations or drive consumers locally extinct. These predictions arise from consumer-resource models incorporating temperaturedependent parameters, and the accuracy of these predictions hinges on the validity of temperature scalings for each parameter. Among all parameters, carrying capacity (K) is the most ill-defined and the temperature scaling of this parameter has no empirically verified foundation. Most studies assume that K declines exponentially with warming, but others have assumed a positive or no relationship between K and temperature. Here, I developed a theoretical foundation for a temperature scaling of K based on physiological principles of temperature and nutrient limitation of phytoplankton growth. The trade-off between thermodynamics and nutrient uptake yields a unimodal thermal response curve for K, and this prediction is supported by empirical data on both phytoplankton and insects. Analyses of consumer-resource models demonstrate the primacy of K in determining predictions of coexistence and stability. Since K exerts a dominant influence on model predictions, ecologists should carefully consider the temperature scaling of K for the species and region in question to ensure accurate estimates of population stability and extinction risk.

Changing temperatures will impact food webs in ways we yet to fully understand. The thermal sensitivities of various physiological and ecological processes differ across organisms and study systems, hindering the generation of accurate predictions. One step towards improving this picture is to acquire a mechanistic understanding of how temperature change impacts trophic interactions before we can scale these insights up to food webs and ecosystems. Here, we implement a mechanistic approach centered on the thermal sensitivity of energetic balances in pairwise consumer-resource interactions, measuring the thermal dependence of energetic gain and loss for two resource and one consumer freshwater species. Quantifying the balance between
