项目摘要

Bees are important not only for their unmatched pollination services but also for their wide range of social behaviours. In my lab, we study the interplay between maternal care and nutritional ecology. Our research focuses on the small carpenter bees as a model for the study of social evolution and pollinator health. We have developed a wide range of tools, techniques, and share open access data of broad relevance to both evolutionary ecologists and conservation biologists. The first part of our research focuses on maternal care and offspring development. We study the small carpenter bees because they are a solitary bee with many social tendencies, including prolonged maternal care, grooming and guarding of offspring, extensive mother-adult offspring interaction, and mutual tolerance of adults in the nest. Further, they are locally abundant and easily tractable in both field and lab settings. We are studying the role of maternal care and mother-offspring interaction on whether offspring develop into tolerant or aggressive individuals. Our studies involve observation colonies which allow us to track mother-offspring interaction and to experimentally modify their nutrition and social environment. We also use genomic methods to identify maternally collected pollen, socially transmitted microorganisms, as well as their effects on offspring gene expression to understand the role of maternal care on offspring nutrition and development. The second part of our research focuses on nutritional ecology and pollinator health. Not only do mothers play a critical role in offspring production and survival, but arguably environmental factors such as food availability, disease, and nesting habit have an overwhelming influence. Our studies demonstrate that bees are sensitive to floral availability not only in terms of the quantity, but also the quality of resources available. Further, there is growing appreciation that core nutrition is complemented by a core microbiome. Bees that are malnourished and combating pathogens have reduced survival and rarely reproduce. We aim to determine the core nutritional requirements and healthy microbiome of bees to inform landscape restoration and conservation practices. With data on nutritional requirements and their availability in the landscape we can better protect pollinator populations. Our research is significant to all Canadians, because our system is unique in permitting experimental assessments of all components that result in a healthy bee. On a practical side, our research also informs pollinator plantings, conservation status recommendations, and bee habitat across a wide range of farm, forest, and urban land use practices. We broadly disseminate information through public lectures, educational websites, school visits, and guided nature walks. The skills that students learn in our lab are directly translated into careers in teaching, research, environmental monitoring, industry, and science communication.
蜜蜂的重要性不仅在于它们无与伦比的授粉服务,还在于它们广泛的社会行为。在我的实验室里,我们研究产妇护理和营养生态学之间的相互作用。我们的研究重点是小型木蜂作为研究社会进化和传粉者健康的模型。我们已经开发了广泛的工具,技术,并共享与进化生态学家和保护生物学家广泛相关的开放获取数据。我们的研究的第一部分集中在产妇护理和后代的发展。我们研究小木蜂,因为它们是一种具有许多社会倾向的独居蜜蜂,包括长期的母性关怀,梳理和保护后代,广泛的母亲与成年后代的互动,以及巢中成年蜜蜂的相互容忍。此外,它们在当地很丰富,在现场和实验室环境中都很容易处理。我们正在研究母亲的照顾和母亲与后代的互动对后代是否发展成为宽容或侵略性个体的作用。我们的研究涉及观察殖民地,使我们能够跟踪母子互动,并通过实验改变他们的营养和社会环境。我们还使用基因组方法来识别母体收集的花粉,社会传播的微生物,以及它们对后代基因表达的影响,以了解母体护理对后代营养和发育的作用。 我们研究的第二部分集中在营养生态学和传粉者健康。母亲不仅在后代的生产和生存中发挥着关键作用,而且可以说环境因素,如食物供应,疾病和筑巢习惯也有压倒性的影响。我们的研究表明,蜜蜂对花卉的可用性不仅在数量上,而且在可用资源的质量上都很敏感。此外,人们越来越认识到核心营养是由核心微生物组补充的。营养不良和与病原体作斗争的蜜蜂生存率降低,很少繁殖。我们的目标是确定蜜蜂的核心营养需求和健康微生物组,为景观恢复和保护实践提供信息。有了关于营养需求及其在景观中可用性的数据,我们可以更好地保护传粉者种群。 我们的研究对所有加拿大人都很重要,因为我们的系统是独一无二的,可以对健康蜜蜂的所有成分进行实验评估。在实践方面,我们的研究还为传粉者种植,保护状况建议以及广泛的农场,森林和城市土地利用实践中的蜜蜂栖息地提供了信息。我们通过公开讲座、教育网站、学校参观和引导自然散步广泛传播信息。学生在我们实验室学习的技能直接转化为教学,研究,环境监测,工业和科学传播的职业生涯。
