Climate change is expected to affect temperature in many ways other than simply increasing the long-term mean. In this organized oral session, speakers will focus on impacts that have been largely neglected in ecological studies such as disproportional nighttime warming in relation to daytime temperatures, changes in the frequency and intensity of extreme events, increases in temperature variability, and the higher frequency of low intensity droughts. This oral session is deliberately broad to reflect the diversity of impacts derived from these phenomena in different ecological systems and processes, providing an enriching discussion that fully agrees with the 2022 meeting theme A Change is Gonna Come. Because these shifts in weather patterns are already occurring and are predicted to be more prevalent with climate change, accounting for research that encompasses biological responses to multiple dimensions of climate change will be critical to guide management processes.
We propose a discussion of neglected aspects of climate change and biological consequences. For example, invasive species in more northern regions may benefit from night warming, since many originate from warmer areas (Ramesh et al., 2017). Native species, with lower optimal night temperatures, may be disadvantaged (e.g., Wu, Ismail, & Ding, 2017). Warmer nights can disrupt key species interactions due to differential thermal tolerance patterns in arthropods and their symbionts (Higashi, Barton, & Oliver, 2020), or result in divergent insect demography and predation pressure in relation to average conditions (Ma et al., 2021). Further, daytime and nighttime warming can have opposite effects on community composition (Barton & Schmitz, 2017), highlighting the need for predictive studies to carefully consider how temperature is changing throughout the day and respective ecological consequences.
Our session will further explore underappreciated dimensions of climate change that can have cascading impacts on individuals, communities and ecosystems. The frequency of low-intensity droughts may result in accumulated stress conditions triggering the rate of mortality of some forest communities and the occurrence of alternative contrasting responses (Sánchez-Pinillos et al., 2021). In addition, extreme weather events lasting only a day to a week can disrupt occurrence and abundance patterns in birds, with species representing certain functional trait groups (e.g., long-distance migrants) disproportionately impacted (Cohen, Fink, & Zuckerberg, 2020). Finally, temperature variability differentially affects disease susceptibility among amphibian hosts across elevational gradients due to a thermal mismatch between hosts and parasites (Cohen et al., 2018). Such studies will guide our discussion and expand the knowledge on the topic.
