Heat tolerance, oxidative stress response tuning, and robust gene activation in early-stageDrosophila melanogasterembryos

ABSTRACT In organisms with complex life cycles, stages that are most susceptible to environmental stress may determine species persistence in the face of climate change. Early embryos Drosophila melanogaster particularly sensitive acute heat stress, yet tropical have higher tolerance than temperate embryos, suggesting adaptive variation embryonic tolerance. We compared transcriptomic responses among and elucidate gene regulatory basis divergence The transcriptomes were differentiated by expression relatively few genes, including genes involved oxidative stress. But response was shared all embryos. Further, shifted thousands showed robust activation, demonstrating that, contrary previous reports, early not transcriptionally silent. involvement corroborates recent reports on critical role redox homeostasis coordinating developmental transitions. By characterizing tolerance, this study is a novel contribution literature physiology genetics, which often lacks ecological evolutionary context.

The city and forest bird flock together in a common garden: genetic and environmental effects drive urban phenotypic divergence

Abstract Urban phenotypic divergences are documented across diverse taxa and commonly assumed to result from microevolution, but the underlying genetic environmental drivers behind these changes unknown in most wild urban systems. We censused common garden studies literature ( N = 77) a range of taxa. Collectively, showed that both plastic responses can contribute divergences, while revealing lack with vertebrates. conducted our own experiment using great tit Parus major ) eggs collected along an urbanization gradient Montpellier, France to: 1) determine whether morphological, physiological, behavioural shifts tits maintained birds forest origins reared 73) 2) evaluate how different sources genetic, early maternal investment, later variation contributed trait experiment. In line divergence wild, had faster breath rates (i.e., higher stress response) were smaller than origins, suggesting differentiation has driven differences. Conversely, differences aggression exploration not garden, indicating plasticity conditions likely drives shifts. Differences between individuals (genetic environmentally induced) explained experiment, among foster nests captive social groups was limited. Among-individual size response similar contexts, whereas among-individual lower wild. Our results provide trait-specific evidence evolution species where change underlies morphology physiology, by plasticity.

The Biological Hierarchy, Time, and Temporal ‘Omics in Evolutionary Biology: A Perspective

Integrative and Comparative Biology, Journal Year: 2022, Volume and Issue: 62(6), P. 1872 - 1886

Published: Sept. 3, 2022

Abstract Sequencing data—genomics, transcriptomics, epigenomics, proteomics, and metabolomics—have revolutionized biological research, enabling a more detailed study of processes, ranging from subcellular to evolutionary, that drive organization. These collectively, are responsible for generating patterns phenotypic variation can operate over dramatically different timescales (milliseconds billions years). While researchers often at specific levels organization isolate processes operating particular scale, the varying types sequence data, or ‘omics, also provide complementary inferences link molecular produce an integrated view evolutionary biology, pathways speciation. We briefly describe how ‘omics has been used across then demonstrate utility integrating sequencing data multiple within same better understand phenomena. However, single-time-point studies cannot evaluate temporal dynamics these processes. Therefore, we put forward as framework enable target Temporal is not infallible, sampling regime directly impacts inferential ability. Thus, discuss role plays in deriving about environmental conditions driving examples impact on inference. Finally, forecast future by highlighting current methodological advancements will be extended species timescales. extend this discussion using multi-omics integrate hierarchy generate variation.

Spring temperature drives phenotypic selection on plasticity of flowering time

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 290(2006)

Published: Sept. 6, 2023

In seasonal environments, a high responsiveness of development to increasing temperatures in spring can infer benefits terms longer growing season, but also costs an increased risk facing unfavourable weather conditions. Still, we know little about how climatic conditions influence the optimal plastic response. Using 22 years field observations for perennial forest herb Lathyrus vernus, assessed phenotypic selection on among-individual variation reaction norms flowering time temperature, and examined if among-year plasticity was associated with temperature We found significant mean plasticity, that plants flowered earlier had more time. Selection favoured individuals lower thermal Less were strongly colder springs, indicating influenced plasticity. Our results show be linked conditions, illustrate understand predict evolutionary responses organisms changing environmental
