Symposium Title: Phenological Plasticity: from Molecular Mechanisms to Ecological and Evolutionary Implications

生活史事件的时间(如迁徙、繁殖、冬眠的时间)统称为物候学，在野外仍然知之甚少。生态学家在解释当前的物候模式以及预测随着全球气候继续变暖时这种模式可能如何变化的能力方面受到了挑战。分子生态学、生理学和人口学的最新进展，加上对野生动物长期的、以个体为基础的研究的积累，将极大地提高我们对气候变化背景下物候变化的集体理解。通过将专注于不同层次组织(从基因和分子到生物体、种群和群落)和不同分类群体的研究人员聚集在一起，我们希望在这个新兴领域内刺激跨学科的讨论和合作。研讨会为早期职业科学家提供机会，如本科生和研究生、博士后研究员、助理教授和初级研究科学家。认识到不同观点的重要性，我们的发言者阵容带来了平衡的性别代表性，并包括来自代表性不足群体的贡献者。主要研讨会的所有发言者将撰写一篇手稿，发表在综合与比较生物学学会的旗舰期刊《综合与比较生物学》杂志上的一期特刊上。除了在ICB上公布成果外，我们还将通过社交媒体广泛宣传和传播研讨会的成果。基本资源可获得性的季节性变化是自然选择的最重要驱动因素之一，这种选择决定了每年反复发生的生命周期事件的阶段和持续时间。季节时间的变化是对气候变化最常见的反应之一，生物体通过表型可塑性或微进化调整其季节时间的能力是弹性的关键组成部分。尽管人们对记录和预测气候变化对物候的影响越来越感兴趣，但我们预测个人、种群和物种可能对环境变化的繁殖时机做出反应的能力受到以下方面的有限知识的限制：1)动物用来调整时机的线索，2)将线索转化为神经和内分泌信号的内源遗传和分子机制，以及3)动物在年度周期内改变其时机和阶段的固有能力。通过将专注于不同等级组织(从基因到生物体、种群和社区)和不同分类小组的研究人员聚集在一起，我们希望刺激围绕这些主题的跨学科合作。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The timing of life history events (e.g. timing of migration, reproduction, hibernation), collectively known as phenology, remains poorly understood in the wild. Ecologists have been challenged in their ability to explain current phenological patterns, as well as predict how such patterns may change as our global climate continues to warm. Recent advances in molecular ecology, physiology, and demography, coupled with the cumulation of long-term, individual-based studies of animals in the wild, will considerably improve our collective understanding of phenological shifts within the context of climate change. By bringing together researchers focused on different hierarchical levels of organization (from genes and molecules to organisms, populations and communities) and different taxonomic groups, we hope to stimulate inter-disciplinary discussion and collaboration within this emerging field. The symposium provides opportunities for early career scientists such as undergraduate and graduate students, postdoctoral fellows, assistant professors, and junior research scientists. Recognizing the importance of diverse perspectives, our speaker line-up brings in balanced gender representation and includes contributors from underrepresented groups. All speakers in the main symposium will be contributing a manuscript for publication in a special issue in the journal Integrative and Comparative Biology, the flagship journal of the Society for Integrative and Comparative Biology. In addition to publication of the results in ICB, we will broadly advertise and disseminate findings of the symposium via social media. Seasonal variation in the availability of essential resources is one of the most important drivers of natural selection on the phasing and duration of annually recurring life-cycle events. Shifts in seasonal timing are among the most commonly reported responses to climate change and the capacity of organisms to adjust their seasonal timing, either through phenotypic plasticity or microevolution, is a critical component of resilience. Despite growing interest in documenting and forecasting the impact of climate change on phenology, our ability to predict how individuals, populations, and species might respond in their timing of reproduction to changes in their environment is constrained by our limited knowledge regarding 1) the cues animals use to adjust timing, 2) the endogenous genetic and molecular mechanisms that transduce cues into neural and endocrine signals, and 3) the inherent capacity of animals to alter their timing and phasing within annual cycles. By bringing together researchers focused on different hierarchical levels of organization (from genes to organisms, populations and communities) and different taxonomic groups, we hope to stimulate inter-disciplinary collaborations around these themes.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
