Abstract Detail
Biodiversity Informatics & Herbarium Digitization Pearson, Katelin [1]. Spring- and fall-flowering species show diverging phenological responses to climate in the Southeast USA. Plant phenological shifts (e.g., earlier flowering dates) are known consequences of climate change that may alter ecosystem functioning, productivity, and ecological interactions across trophic levels. Temperate, subalpine, and alpine regions have largely experienced advancement of spring phenology with climate warming, but the effects of climate change in warm, humid regions and on autumn phenology are less well understood. I used nearly 10,000 digitized herbarium specimen records to examine the phenological sensitivities of fall- and spring-flowering asteraceous plants to temperature and precipitation in the U.S. Southeastern Coastal Plain. Climate data reveal warming trends in this already warm climate, and spring- and fall-flowering species responded differently to this change. Results suggest that even warm, humid regions may experience phenological shifts and thus be susceptible to potentially detrimental effects such as plant-pollinator asynchrony.
