摘要

休眠是水蚤属淡水甲壳类动物的一种生存策略，包括通过基因编码抑制生物体的生长、发育和繁殖。虽然水蚤产生停顿期胚胎的环境诱因和诱导孵化的环境诱因已被充分记录，但在不同的停顿期子阶段，环境挑战的影响仍有待探索。在这项研究中，我们在指定的休眠亚阶段将大型水蚤的休眠胚胎暴露在不同的温度和光照条件下。我们的研究结果强调了母体环境对准备进入休眠期的胚胎的重要性。此外，我们还展示了一个强制性发育停滞期，在此期间无法触发发育重启。此外，我们还展示了胚胎在孵化过程中根据环境变化调整孵化的能力。这项研究揭示了水蚤胚胎在休眠期的固有发育模式及其对环境变化的适应能力。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
