Evaluating the Effects of Climate on the Phenology of Host and Nectar Sources for the Endangered Karner Blue Butterfly (Lycaeides melissa samuelis).

Climatic changes are impacting ecosystems across the globe. Changing temperatures have been shown to advance bloom times of flowering plants, which can have detrimental consequences for obligate pollinator species, however, much more research is needed. The federally endangered Karner blue butterfly (KBB) utilizes a single host plant for the larval stage of its life cycle, wild lupine (Lupinus perennis), and as adults feeds on a variety of forbs. KBB are bivoltine, having two broods per year. Advances in bloom times and senescence of wild lupine, as well as the bloom times of other nectar sources may have negative impacts on KBB populations, if bloom times and butterfly emergence are not synchronized. For this study I propose to evaluate 1) how varying levels of forest canopy cover affect forest floor temperatures and subsequent timing of phenology in lupine and other KBB nectar sources, and 2) evaluate the response of KBB to timing of phenology in these host and nectar species.
