“…We can turn to a non‐herbivorous system as an example Carbonell & Stoks (2020) recently documented evolutionary changes in the thermal performance curves of the European damselfly ( Ischnura elegans ) during its range expansion toward warmer regions. Yet examples of the evolution of thermal performance curves under climate change are rare (Tüzün & Stoks, 2018), and more such studies are needed in herbivores , as it remains unclear whether standing genetic variation for heat resistance is adequate for sustained responses to selection (Kellermann et al ., 2012; Kellermann & van Heerwaarden, 2019).…”

“…While development refers to the rate at which organisms go through developmental stages, growth refers to the increase in mass over time (Van der Have and de Jong 1996). Intriguingly, moving to colder regions may also result in faster development and growth rates because of countergradient variation where populations evolve a faster life history through selection imposed by the stronger time constraints in cooler environments (Conover et al 2009, Tüzün and Stoks 2018). Countergradient variation occurs when selection results in genetic adaptation that counteracts environmental effects such that a similar phenotype is maintained across environments (Levins 1968, 1969, Eckhart et al 2004).…”

Species' range edges are expanding to both warmer and cooler regions. Yet, no studies directly compared the changes in range-limiting traits within the same species during both types of range expansions. To increase our mechanistic understanding of range expansions, it is crucial to disentangle the contributions of plastic and genetic changes in these traits. The aim of this study was to test for plastic and evolutionary changes in heat tolerance, life history, and behavior, and compare these during range expansions toward warmer and cooler regions. Using laboratory experiments we reconstructed the thermal performance curves (TPCurves) of larval life history (survival, growth, and development rates) and larval heat tolerance (CTmax) across two recent range expansions from the core populations in southern France toward a warmer (southeastern Spain) and a cooler (northwestern Spain) region in Europe by the damselfly Ischnura elegans. First-generation larvae from field-collected mothers were reared across a range of temperatures (16°-28°C) in incubators. The range expansion to the warmer region was associated with the evolution of a greater ability to cope with high temperatures (increased mean and thermal plasticity of CTmax), faster development, and, in part, a faster growth, indicating a higher time constraints caused by a shorter time frame available for larval development associated with a transition to a greater voltinism. Our results thereby support the emerging pattern that plasticity in heat tolerance alone is inadequate to adapt to new thermal regimes. The range expansion to the cooler region was associated with faster growth indicating countergradient variation without a change in CTmax. The evolution of a faster growth rate during both range expansions could be explained by a greater digestive efficiency rather than an increased food intake. Our results highlight that range expansions to warmer and cooler regions can result in similar evolutionary changes in the TPCurves for life history, and no opposite changes in heat tolerance.

“…Such responses may cause TPCs to shift as a result of adaptation to the local thermal conditions (Conover, Duffy, & Hice, ; Sinclair et al, ). Shifts in TPCs typically take one of two forms (Conover et al, ; Tüzün & Stoks, ). A ‘horizontal shift’ occurs when warm‐adapted populations perform better at higher temperatures compared to cold‐adapted populations and vice versa.…”

1. Trait-based studies are needed to understand the plastic and genetic responses of organisms to warming. A neglected organismal trait is elemental composition, despite its potential to cascade into effects on the ecosystem level.2. Warming is predicted to shape elemental composition through shifts in storage molecules associated with responses in growth, body size and metabolic rate. Our goals were to quantify thermal response patterns in body composition and to obtain insights into their underlying drivers and their evolution across latitudes.3. We reconstructed the thermal response curves (TRCs) for body elemental composition [C (carbon), N (nitrogen) and the C:N ratio] of damselfly larvae from highand low-latitude populations. Additionally, we quantified the TRCs for survival, growth and development rates and body size to assess local thermal adaptation, as well as the TRCs for metabolic rate and key macromolecules (proteins, fat, sugars and cuticular melanin and chitin) as these may underlie the elemental TRCs. 4. All larvae died at 36°C. Up to 32°C, low-latitude larvae increased growth and development rates and did not suffer increased mortality. Instead, growth and development rates of high-latitude larvae were lower and levelled off at 24°C, and mortality increased at 32°C. This latitude-associated thermal adaptation pattern matched the 'hotter-is-better' hypothesis. With increasing temperatures, lowlatitude larvae decreased C:N, while high-latitude larvae increased C:N. These patterns were driven by associated changes in N contents, while C contents did not respond to temperature. Consistent with the temperature-size rule and the thermal melanism hypothesis, body size and melanin levels decreased with warming. While all traits and associated macromolecules (except for metabolic rate that showed thermal compensation) assumed to underlie thermal responses in elemental composition showed thermal plasticity, these were largely independent and none could explain the stoichiometric TRCs. 5. Our results highlight that thermal responses in elemental composition cannot be explained by traditionally assumed drivers, asking for a broader perspective including the thermal dependence of elemental fluxes. Another key implication is that thermal evolution can reverse the plastic stoichiometric thermal responses Additional supporting information may be found online in the Supporting Information section at the end of the article.
