Dr. Zoe Panchen The blossoming of the Arctic: Natural history records as a resource to study plant responses to climate change The Arctic is experiencing some of the most dramatic changes in climate with temperatures rising at treble the rate of the global average. Phenology, the timing of natures seasonal events, is often related to temperature and, as the climate warms, Arctic flowering and fruiting times are generally shifting earlier. Natural History records of pressed plants (herbarium specimens) are often collected in flower or fruit and offer a snap shot of flowering and fruiting times over the past century or more. Herbarium specimens are thus an excellent resource for predicting how plants will respond to climate change. In this talk, I will discuss how Arctic plants are responding to climate change, focusing on findings from my Nunavut plant phenology research using herbarium specimens and long-term phenology monitoring. I will conclude my presentation by describing my current research on evolutionary and life history trait patterns in Arctic plant phenological responses to climate change.
