Shorter flowering seasons and declining abundance of flower visitors in a warmer Arctic

Abstract

Climate-induced changes in phenology have the potential to push trophic relationships out of synchrony, but evidence of this phenomenon is scant, particularly in the Arctic. A long-term (1996–2009), spatially replicated data set from high-Arctic Greenland now indicates a climate-associated shortening of the flowering season, and a concomitant decline in flower visitor abundance.
