“…S1), and this variability could play an important role in shaping species’ responses to change ( 3 ). For example, variable environments could select for plasticity ( 47 ) with implications for adaptation ( 48 ). Future work assessing how different temporal scales of environmental variability (i.e., diel, semidiel, and seasonal) or predictability alter species’ performance will help to further elucidate the role of variability in structuring evolutionary responses to global change.…”

Variation in environmental conditions across a species’ range can alter their responses to environmental change through local adaptation and acclimation. Evolutionary responses, however, may be challenged in ecosystems with tightly coupled environmental conditions, where changes in the covariance of environmental factors may make it more difficult for species to adapt to global change. Here, we conduct a 3-month-long mesocosm experiment and find evidence for local adaptation/acclimation in populations of red sea urchins, Mesocentrotus franciscanus , to multiple environmental drivers. Moreover, populations differ in their response to projected concurrent changes in pH, temperature, and dissolved oxygen. Our results highlight the potential for local adaptation/acclimation to multivariate environmental regimes but suggest that thresholds in responses to a single environmental variable, such as temperature, may be more important than changes to environmental covariance. Therefore, identifying physiological thresholds in key environmental drivers may be particularly useful for preserving biodiversity and ecosystem functioning.

“…Environmental change is complex, and our ability to predict evolutionary responses to it is still poor (Rescan et al, 2022). In particular, there is growing recognition of the need to better account for the complexity of temporal environmental change in biological predictions (Bates et al, 2018;Dillon et al, 2016;Helmuth et al, 2014;Vinton et al, 2022). Our brief review of theory on adaptation to temporal environmental change identified two key gaps.…”

“…Populations in highly-stochastic environments may thus be prone to genetic drift, risking loss of genetic diversity and fitness (Lande & Shannon, 1996;Tufto, 2015). In general, however, we still lack a thorough understanding of how different components of environmental change combine to shape adaptation and plasticity, and their rates of evolution, across populations and landscapes (Catullo et al, 2019;Rescan et al, 2022;Shaw & Etterson, 2012;Vinton et al, 2022;Visser, 2008). This understanding is crucial to predicting adaptive capacity and persistence under the fast-paced and complex nature of climate change.…”

Environmental change drives evolutionary adaptation, which determines geographic patterns of biodiversity. At a time of rapid environmental change, however, our ability to predict its evolutionary impacts is far from complete. Temporal environmental change, in particular, often involves joint changes in major components such as mean, trend, cyclic change, and noise. While theoretical predictions exist for adaptation to temporal change in isolated components, knowledge gaps remain. To identify those gaps, we review the relevant theoretical literature, finding that studies rarely assess the relative effects of components changing simultaneously, or attempt to translate theoretical predictions to field conditions. To address those gaps, we draw on classic evolutionary theory to develop a model for the evolution of environmental tolerance, determined by an evolving phenotypically plastic trait, in response to major components of temporal environmental change. We assess the effects of different components on the evolution of tolerance, including rates of adaptation towards new environmental optima, and the evolution of plasticity. We retrieve and synthesize earlier predictions of responses to components changing in isolation, while also generating new predictions of responses to components changing simultaneously. Notably, we show how different forms of environmental predictability emerging from the interplay of cyclic change, stochastic change (noise), and generation time shape predicted outcomes. We then parameterise our model using temperature time series from global marine hotspot in southern Australia, illustrating its utility for predicting testable geographic patterns in evolved thermal tolerance. Our framework provides new insights into the evolution of adaptation and plasticity under temporal environmental change, while offering a path to improving predictions of biological responses to climate change.

Dissecting plant responses to the environment is key to understanding if and how plants adapt to anthropogenic climate change. Stomata, plants' pores for gas exchange, are expected to decrease in density following increased CO2 concentrations, a trend already observed in multiple plant species. However, it is unclear if such responses are based on genetic changes and evolutionary adaptation. Here we make use of extensive knowledge of 43 genes in the stomatal development pathway and newly generated genome information of 191 A. thaliana historical herbarium specimens collected over the last 193 years to directly link genetic variation with climate change. While we find that the essential transcription factors SPCH, MUTE and FAMA, central to stomatal development, are under strong evolutionary constraints, several regulators of stomatal development show signs of local adaptation in contemporary samples from different geographic regions. We then develop a polygenic score based on known effects of gene knock-out on stomatal development that recovers a classic pattern of stomatal density decrease over the last centuries without requiring direct phenotype observation of historical samples. This approach combining historical genomics with functional experimental knowledge could allow further investigations of how different, even in historical samples unmeasurable, cellular plant phenotypes have already responded to climate change through adaptive evolution.
