Abstract Decades of research have illuminated the underlying ingredients that determine scope evolutionary responses to climate change. The field biology therefore stands ready take what it has learned about influences upon rate adaptive evolution—such as population demography, generation time, and standing genetic variation—and apply assess if how populations can evolve fast enough “keep pace” with Here, our review highlights contribute still needs learn provide more mechanistic predictions winners losers We begin by developing broad for contemporary evolution change based on theory. then discuss methods assessing climate‐driven evolution, including quantitative studies, experimental space‐for‐time substitutions. After providing this mechanism‐focused overview both evidence specifically, evolving keep pace change, we next consider factors limit actual responses. In context, dual role phenotypic plasticity in facilitating but also impeding Finally, detail a deeper consideration constraints improve forecasts inform conservation management decisions.

When the notion of climate change emerged over 200 years ago, few speculated as to impact rising atmospheric temperatures on biological life. Tens decades later, research clearly demonstrates that life Earth is enormous, ongoing, and with foreseen effects lasting well into next century. Responses have been widely documented. However, breadth phenotypic traits involved evolutionary adaptation remains unclear. In addition, it difficult identify genetic and/or epigenetic bases phenotypes adaptive change, in part because often not clear whether this plastic, genetic, or some combination two. Adaptive responses climate-driven selection also interact other processes driving changes general, including demography driven by factors. Special Issue, we explore factors will overall outcome adaptation. Our contributions explain include only classic phenomena, such range shifts environmentally dependent sex determination, but overlooked phenomena social sexual conflicts expression stress hormones. We learn how can be mediated via both natural selection, effectively influencing key fitness-related offspring growth fertility potential. Finally, limits opportunities for predicting change. This contribution forms basis 10 actions believe improve predictions when organisms may adapt genetically anticipate Issue inform novel investigations unfold from genotypes, particularly methodologies increasingly allow researchers study field experiments.

Abstract Heatwaves are increasing in frequency and severity, posing a significant threat to organisms globally. In aquatic environments heatwaves often associated with low environmental oxygen, which is deadly combination for fish. However, surprisingly little known about the capacity of fishes withstand these interacting stressors. This issue particularly critical species extreme conservation concern such as sturgeon. We assessed tolerance juvenile white sturgeon from an endangered population heatwave exposure investigated how this affects additional acute measured whole-animal thermal hypoxic performance underlying epigenetic transcriptional mechanisms. Sturgeon exposed simulated had increased exhibited complete compensation effects hypoxia. These changes were increase mRNA levels involved stress ( hsp90a, hsp90b, hsp70 hif1a ) following Global DNA methylation was sensitive rapidly responded hypoxia over course hour. data demonstrate that exhibit substantial resilience heatwaves, improved cross-tolerance stressors involving rapid responses both

Abstract Many species are threatened by climate change and must rapidly respond to survive in changing environments. Epigenetic modifications, such as DNA methylation, can facilitate plastic responses regulating gene expression response environmental cues. Understanding epigenetic is therefore essential for predicting species' ability adapt the context of global change. Here, we investigated functional significance different methylation‐associated cellular processes on temperature‐dependent life history seed beetles, Callosobruchus maculatus Fabricius 1775 (Coleoptera: Bruchidae). We assessed changes under thermal stress (1) methyltransferase ( Dnmt1 Dnmt2 ) levels, (2) genome‐wide methylation (3) reproductive performance, with following treatment 3‐aminobenzamide (3AB) zebularine (Zeb) over two generations. These drugs well‐documented alter across tree life. found that were expressed throughout body males females, but highly females compared exhibited temperature dependence. However, whole‐genome did not significantly vary temperature, only marginally or inconclusively drug treatment. Both 3AB Zeb led profound shifts female trade‐off allocation, often increasing fitness control beetles. Mismatch between magnitude effects versus suggest potential trade‐offs via repair recycling processes, rather than addition (subtle) methylation. Together, our results mechanisms relating Dnmt expression, pathways, possibly strongly implicated modulating insect
