Changes in phenology due to climate warming could disrupt temporal overlap between interacting organisms when previously synchronized species respond to climate change at different rates. Phenologies of plants and insects are known to be sensitive to temperature and/or timing of snowmelt, with warmer temperatures and earlier snowmelt generally advancing spring flowering and emergence; however, some groups of pollinators, such as solitary bees, have been little explored in this context. One striking aspect of eastern hardwood forests is the emergence of understory wildflowers each spring, most of which rely, at least to some extent, on wild native pollinators for seed set. Without an understanding of the environmental drivers of phenology of these species, we have little ability to predict whether pollinators will continue to be well synchronized with flowering as the climate changes. In this study, I determined how spring temperatures and timing of snowmelt influence the phenology of spring wildflowers, activity of bees, and their temporal overlap in Gatineau Park, Québec. From 2013 to 2018, I characterized bee activity phenology and flowering phenology of understory plants in multiple study plots, focusing on early-flowering Anemone spp. and later-flowering Trillium grandiflorum. The sampled bee community was dominated by Andrena, Lasioglossum, and Nomada, all of which have similar activity periods. Degree-day accumulation was a better predictor of Anemone and Nomada phenology than were day of year or snowmelt date, whereas T. grandiflorum appeared to be more sensitive to photoperiodic cues; since day of year was the variable that best described its phenology. Activity periods of Andrena and Lasioglossum were equally well described by degree-day accumulation and by day of year. No taxon's phenology was best predicted by snowmelt date. Despite these differences among taxa in the identities of the best predictors of phenology, bee activity and plant flowering phenologies responded at similar rates to interannual and among-site variation in snowmelt date and early spring temperature. Temporal overlap between flowering and bee activity was similar over the years of this study and was affected neither by snowmelt date nor by temperature. These results suggest that interacting plant and bee taxa may respond to different environmental variables but still maintain their synchrony under the conditions recorded so far.

Early in the year, our North American forests come to life as native wildflowers start to push up through patches of snow. With longer days and sunlight streaming down through bare branches of towering trees, life on the forest floor awakens from its winter sleep. Plants such as green dragon, squirrel corn, and bloodroot interact with their pollinators and seed dispersers and rush to create new life before the trees above leaf out and block the sun's rays. Wake Up, Woods showcases the splendor of our warming forests and offers clues to nature's annual springtime floral show as we walk in our parks and wilderness areas, or even in shade gardens around our homes. Readers of Wake Up, Woods will see that Gillian Harris, Michael Homoya and Shane Gibson, through illustrations and text, present a captivating look into our forests' biodiversity, showing how species depend on plants for food and help assure plant reproduction. This book celebrates some of nature's most fascinating moments that happen in forests where we live and play.

This volume presents a detailed description of more than thirty-five wildflower species of the Northeast, describing their colors, habitats, range, pollination, history, cultural lore, medicinal uses, and literary and artistic references. The spring-blooming wildflowers looked at range from old favorites to lesser-known species. Featuring more than 500 full-color photos in large-sized format, the book delves deep into the life histories, lore, and cultural uses of more than 35 plant species. The narrative covers topics such as the naming of wildflowers; the reasons for taxonomic changes; pollination of flowers and dispersal of seeds; uses by Native Americans; related species in other parts of the world; herbivores, plant pathogens, and pests; medicinal uses; and wildflower references in history, literature, and art. The photos capture the beauty of these plants and also illustrate the concepts discussed in the text.
