Phenology, the seasonal timing of life-history events, is a major determinant of the abiotic environment and ecological interactions that species experience. Phenological plasticity, or the responsiveness of phenology to differences in inter-annual climatic conditions, is one of the ways that species cope with environmental variability and climatic shifts. Shifts in spring plant phenology are one of the clearest biotic signals of recent anthropogenic climate change, as temperatures have increased in much of the world, and many plant species have been documented to bloom and leaf-out earlier. While these patterns have been well documented, much less has been understood about the phenological plasticity of pollinators that depend on flowering plants, such as bees. Here, I investigate several aspects of bee phenology and the effect of climate change on phenological variability broadly.This dissertation is composed of six chapters, with four manuscripts bookended by introductory and concluding chapters. Chapter 2 examines the drivers of bee phenology in a subalpine bee community, quantifying the relative effects of inter-annual climate variability, topography, and species traits on the emergence, peak, and senescence timing of several dozen bee species over a decade. Using the same dataset and a complementary long-term flower phenology monitoring dataset, Chapter 3 quantifies the degree to which bee and flower phenological distributions are skewed toward early- or late-season abundance. Synthesizing work from Chapters 2 and 3, Chapter 4 presents a mechanistic model of bee phenology that is based on demographic rates and is parameterized using Halictus rubicundus abundance data collected at a fine temporal scale. Expanding the scope of inquiry, Chapter 5 investigates the degree to which the spring phenology of over a thousand species of plants, insects, and birds is becoming more or less variable across years as a result of climate change.
