“…This finding showed that tolerance to the insecticide declined after HIT treatment, confirming the phenomenon of climate‐induced toxicant sensitivity 13,54,55 . The synergistic effects of thermal and insecticide exposure could be explained as follows: (1) the organisms did not recover fully from the first stressor, and subsequent exposure to another stressor produced stronger effects 56 ; or (2) the organism depleted its energy while coping with the first stressor, such that it could not defend itself against the second stressor, thereby aggravating the impacts of the latter 10 …”

“…The abiotic environment is vital to the development of most organisms, 1–3 and the earlier experience of this environment regulates development, but also partly induces it 4–6 . Previous studies have suggested that earlier experiences of environmental stressors can prompt plasticity responses 7 in fitness traits, including development, longevity and fecundity, 8,9 or induce changes in tolerance to other stressors 10,11 . Thus, exploring how adaptation to one environmental stressor impacts the tolerance and phenotypic plasticity to other stressors requires attention in a rapidly changing world.…”

“…In particular, species with relatively short life cycles are increasingly likely to experience the stressor at various stages during development. Consequently, the complex interaction of different stressors at varying stages is essential for predicting acclimation capacities or evolutionary adaptation in a changing environment 10 . Diverse stressors experienced at early life stages influence not only the contemporary fitness traits, but also the fitness of the offspring through transgenerational effects 17–20 …”

BACKGROUND Experience of an earlier environment plays an important role in the induction of delayed and even intergenerational phenotypes of an organism. Evidence suggests that rapid adaptation to an environmental stressor can change the performance of organisms, and even enable them to deal with other stressors. The goal of this study was to determine the effects of adult imidacloprid exposure on life‐history traits within and between generations of the cereal aphid, Sitobion avenae, under three developmental conditions: constant temperature, 22°C; a low‐intensity thermal condition, 22 + 34°C for 2 h per day; and a high‐intensity thermal condition, 22 + 38°C for 2 h per day. RESULTS Early thermal experience not only changed the tolerance of S. avenae to the insecticide, imidacloprid, but also caused adults to incur fitness costs: the higher the heat intensity, the higher the costs. Negative transgenerational impacts of combined heat and insecticide stressors were limited to the developmental stage, whereas positive stimulation of heat intensity was observed during the adult stage. Overall, nymphal thermal experience exacerbated the detrimental effects of adult insecticidal exposure on the intrinsic rate of population increase in the maternal generation, but stimulated a net reproductive rate in the succeeding offspring generation. CONCLUSION These findings underpin the importance of considering the experience of the early developmental environment, but also enhance our understanding of the transgenerational effects of combined thermal and insecticide stressors on the population fate of S. avenae. They also help to assess the efficacy of chemical control in a warming world. © 2021 Society of Chemical Industry.

“…Interestingly, MDA, which is a degradation product of polyunsaturated fatty acids and thus a marker for lipid peroxidation through ROS (Liu et al 1997 ; Janssens et al 2017 ), was lower in Swedish than in Italian or German individuals. The reduced oxidative damage may be related to relatively high levels of antioxidants (here: GSH) in Swedish individuals.…”

Clinal variation in investment into reproduction versus maintenance suggests a ‘pace-of-life’ syndrome in a widespread butterfly

Extreme weather events such as heat waves are predicted to increase in the course of anthropogenic climate change. Widespread species are exposed to a variety of environmental conditions throughout their distribution range, often resulting in local adaptation. Consequently, populations from different regions may vary in their capacity to deal with challenging conditions such as thermal stress. In this study, we investigated clinal variation in body size, fecundity, and oxidative markers along a pan-European latitudinal gradient in the green-veined white butterfly Pieris napi, and additionally gene expression in German individuals. We exposed butterflies from replicated Italian, German, and Swedish populations to cold, control, or hot temperatures for 24 h. Under hot conditions, molecular chaperones were up-regulated, while oxidative damage remained unaffected and levels of the antioxidant glutathione (GSH) were reduced under cold and hot conditions. Thus, the short-term exposure to heat stress did not substantially affect oxidative balance. Moreover, we found decreased body size and fecundity in cooler compared with warmer regions. Interestingly, oxidative damage was lowest in Swedish animals exhibiting (1) high levels of GSH, (2) low early fecundity, and (3) low larval growth rates. These results suggest that Swedish butterflies have a slower life style and invest more strongly into maintenance, while those from warmer regions show the opposite pattern, which may reflect a 'pace-of-life' syndrome.

“…Species confronted with novel habitats face numerous challenges in the form of changes to the physical and/or biotic environment (Hobbs et al 2009). Consequently, successful colonization of anthropogenic landscapes is likely to require adjustments at multiple levels and urban animals often differ from their rural conspecifics in terms of behaviour (reviewed in Sol et al 2013), morphology (Winchell et al 2016;Janssens et al 2017;Kern & Langerhans 2018;Merckx et al 2018a) and life-history or physiological traits (Sprau et al 2017;Tüzün et al 2017a;Diamond et al 2018;Sepp et al 2018). Both genetic differentiation and phenotypic plasticity may contribute to such landscape-related differences, although the relative contribution of each mechanism is often difficult to assess.…”

During the last century, the human footprint on natural ecosystems has increased strongly and human-altered habitats such as urban and agricultural areas have extended globally. Despite their negative impacts on biodiversity, these habitats offer unique opportunities to study how native species respond to novel environmental conditions. Here, we studied phenotypic divergence associated with colonization of human-altered habitats in the Speckled wood (Pararge aegeria). We reared butterflies of woodland, urban and agricultural origins under common garden conditions and we measured boldness and activity at the adult stage. Both behavioural traits were repeatable at the individual level (i.e. personality traits), but we found weak evidence for ecotype-related differences in mean boldness and activity. In line with urban areas being stressful habitats, we found that boldness and activity traits correlate in urban butterflies, while we found no such syndrome pattern in woodland and agricultural butterflies.Our results show that urbanization can alter some aspects of personality in an insect species, but they do not support the assumption that anthropogenic habitats favour boldness. Significance statementHuman activities such as urbanization and intensive agriculture strongly alter terrestrial ecosystems and they are among the most significant threats to biodiversity. To tolerate humandominated landscapes, many vertebrate species show behavioural shifts towards bold personalities, but similar responses remain rather overlooked in invertebrate taxa. Here, we studied the progeny of woodland, agricultural and urban Speckled woods reared under common garden conditions and we assessed their personality. We found little evidence for differences in personality traits among landscape types, but the behavioural syndrome linking boldness and 3 activity was detected only in urban butterflies. This shows that urbanization can indeed shape some aspects of personality in invertebrates.
