“…This is evidenced by a prolonged development time and reduced larval growth rate, body mass, fat content, and PO activity when having fed on plants grown at the higher rather than lower temperature. These findings are in line with other studies on insects (Bauerfeind & Fischer, 2013a; Kuczyk, Müller, et al, 2021; Kuczyk, Raharivololoniaina, et al, 2021; but Raharivololoniaina et al, 2021). The specific mechanisms underlying the reduced performance are unclear, but temperature‐mediated changes in leaf glucosinolate, carbon, and carbon:nitrogen ratio, as have been documented in S .…”

“…These “warm‐adapted” populations appear, therefore, to be more at risk from climate change than their northern counterparts, potentially reflecting a cost of their rapid lifestyle (Günter, Beaulieu, Freiberg, et al, 2020 ; Günter, Beaulieu, Freiberg, et al, 2020 ). We believe that our results have wide‐ranging implications also for other herbivorous insects, as it seems likely that climate change will have pronounced effects on plant chemistry (DeLucia et al, 2012 ; Kuczyk, Müller, et al, 2021 ; Kuczyk, Raharivololoniaina, et al, 2021 ; Suseela & Tharayil, 2018 ). It seems also conceivable that time‐stressed species or populations respond generally more strongly to poor food quality, based on a high demand for nutrients to fuel rapid development.…”

“…Food quality is an important selective pressure (Chown & Gaston, 2010 ), and its effects on herbivores have been widely documented (Awmack & Leather, 2002 ; Scriber & Slansky, 1981 ). Some recent studies on butterflies, for instance, showed that feeding on plants grown at higher temperatures reduces insect performance, indicated by decreased body size, prolonged development time, and a reduced efficiency of converting food into body matter (Bauerfeind & Fischer, 2013a ; Kuczyk, Müller, et al, 2021 ; Kuczyk, Raharivololoniaina, et al, 2021 ). With regard to water availability, drought stress may increase plant quality for insects, as evidenced by increased reproductive performance, growth rate, and body size (Franzke & Reinhold, 2011 ; Kuczyk, Müller, et al, 2021 ; Larsson, 1989 ; Salgado & Saastamoinen, 2019 ).…”

Anthropogenic climate change poses a substantial challenge to many organisms, to which they need to respond to avoid fitness reductions. Investigating responses to environmental change is particularly interesting in herbivores, as they are potentially affected by indirect effects mediated via variation in host‐plant quality. We here use the herbivorous insect Pieris napi to investigate geographic variation in the response to variation in food quality. We performed a common garden experiment using replicated populations from Germany and Italy, and manipulated host quality by growing host plants at different temperature and water regimes. We found that feeding on plants grown at a higher temperature generally diminished the performance of P. napi, evidenced by a prolonged development time and reduced larval growth rate, body mass, fat content, and phenoloxidase activity. Genotype by environment interactions (G × E) were present in several performance traits, indicating that Italian populations (1) respond more strongly to variation in host‐plant quality and (2) are more sensitive to poor food quality than German ones. This may reflect a cost of the rapid lifestyle found in Italian populations. Consequently, German populations may be more resilient against environmental perturbations and may perhaps even benefit from warmer temperatures, while Italian populations will likely suffer from the concomitantly reduced host‐plant quality. Our study thus exemplifies how investigating G × E may help to better understand the vulnerability of populations to climate change.

Climate change has an impact on ecosystem structure and function globally by altering the relationships between plants and soil organisms. Despite the fact that water is the most plentiful molecule on Earth's surface, water scarcity is the element that most severely limits global terrestrial plant production. Little is known about the climatic factors that drive phenological responses to climate change, and less attention has been paid to the fact that phenology is also responsive to other climatic. The aim of this study was to assess the impacts of climate change on plant water interactions. This study was guided by the specific objectives, which included examining the relationship between climate change and plant function; finding out the impacts of climate change on plant water interactions; and assessing how plants handle water scarcity. It was found that there was a linkage between climate change and plant function. The evaporation of water molecules from the outer surfaces of the mesophyll cells initiates the upward transpiration pull in the leaves, and respiring starches and sugars are created during photosynthetic processes using sunlight energy. Climate change enhanced the most enormous movement of species that has occurred without direct human intervention. It was also found that precipitation was a key driver of phenological changes in desert ecosystems. It was also found that drought was one of the most significant biotic challenges faced by plants, with considerable genetic variation in water deficit responses. There is a need for research on climate change to ease biodiversity conservation.
