Abstract To mitigate the effects of climate change, it is important to understand species' responses increasing temperatures. This has often been done by studying survival or activity at temperature extremes. Before such extremes are reached, however, on fertility may already be apparent. Sex differences in thermal sensitivity (TSF) could impact species persistence under warming because female typically more limiting population growth than male fertility. However, little known about sex TSF. Here we first demonstrate that mating system can strongly influence TSF using seed beetle Callosobruchus maculatus . We exposed populations carrying artificially induced mutations two generations short‐term experimental evolution alternative systems, manipulating opportunity for natural and sexual selection mutations. then measured males females subjected juvenile adult heat stress. Populations kept had higher fitness, but similar TSF, compared control relaxed selection. males, strikingly, this difference increased over only evolving hypothesized an increase male‐induced harm during played a central role driving evolved difference, indeed, remating conditions harassment reduced both Moreover, show manipulation parameters C. generates intraspecific variation equal found among diverse set studies insects.

Abstract Climate change is affecting population growth rates of ectothermic pests with potentially dire consequences for agriculture and global food security. However, current projection models pest impact typically overlook the potential rapid genetic adaptation, making forecasts uncertain. Here, we predict how climate adaptation in life-history traits insect affects their on agricultural yields by unifying thermodynamics classic theory resource acquisition allocation trade-offs between foraging, reproduction, maintenance. Our model predicts that warming temperatures will favour towards maintenance coupled increased through larval evolution this strategy results both per capita host consumption, causing a double-blow yields. We find support these predictions studying thermal gene expression wide-spread pest, Callosobruchus maculatus ; 5 years under experimental an almost two-fold increase its predicted footprint.

Abstract Temperature influences nearly all aspects of fitness. However, reproduction is often more thermally sensitive than survival. Thermoregulation must maintain performance in both components fitness to buffer populations from environmental change. We assessed the benefits thermoregulation Enchenopa binotata treehoppers. Under realistic mesocosm conditions, we quantified fine‐scale microclimates using 3D‐printed operative temperature models. then compared temperatures treehopper body and translated patterns into variation survival reproduction. also two thermoregulatory mechanisms: precise microclimate choice heat‐escape behaviours. Finally, applied our results evaluate if arthropod accurately characterized by theoretical models commonly used simulate responses found substantial thermal at fine spatial scales relevant insects: a single point time, within 30‐cm‐tall plants spanned ranges up 19°C (23–42°C). Lethal were common when air high. heat escapes allowed treehoppers almost entirely avoid lethal temperatures.

Adaptation to different climates fuels the origins and maintenance of biodiversity. Detailing how organisms optimize fitness for their local is therefore an essential goal in biology. Although we increasingly understand survival-related traits evolve as adapt climatic conditions, it unclear whether also that coordinate mating between sexes. Here, show dragonflies consistently warmer across space time by evolving less male melanin ornamentation-a mating-related trait absorbs solar radiation heats individuals above ambient temperatures. Continent-wide macroevolutionary analyses reveal species inhabiting ornamentation.

Observations from 2005 2019 detail contemporary selective pressures oppose ornaments years; our climate-warming projections predict further decreases 2070. Conversely, female ornamentation responds idiosyncratically temperature time, indicating sexes ways meet demands climate. Overall, these macro- microevolutionary findings demonstrate predictably climate just they do traits.

Abstract In light of the increased frequency heatwaves due to climate change, it is crucial better understand their potential effects on animal reproduction. Heat stress can affect all aspects reproduction, including gamete development, fertilisation success, parental care and offspring survival. We may, therefore, expect these be highly sensitive timing a heatwave event relative an organism's reproductive cycle. Here, we use insect study system ( Nicrophorus vespilloides ) test whether variation in within short timeframe has differential success fitness. found that had little no effect when they occurred few days before or after mating, but were detrimental for fitness if during mating. Individuals experienced mating significantly less likely have successful breeding bout, longer smaller suffered lower survival rate.

Significance Organisms are increasingly challenged by increasing temperatures due to climate change. In insects, body strongly affected ambient temperatures, and insects therefore expected suffer from heat stress, potentially reducing survival reproductive success leading elevated extinction risks. We investigated how temperature fitness in two insect species the temperate zone. Male female survivorship benefitted more low than did success, which increased with higher revealing a thermal conflict between components. plasticity reduced survival, natural sexual selection operated on such plasticity.
