Impacts of a millennium drought on butterfly faunal dynamics

M. L. Forister, J. A. Fordyce, C. C. Nice, J. H. Thorne, D. P. Waetjen, A. M. Shapiro

This study examines how a millennium drought affected butterfly populations in northern California, showing differential impacts at low and high elevations based on phenological shifts and flight season length.
