Effects of frost on wildflowers: an unexpected consequence of climate change--image 22 of 22

Thumbnail
The ratio of flowers/butterfly (Erigeron speciosus to Speyeria mormonia) in year t is a good predictor of the change in the size of the Mormon fritillary butterfly population from year t to the next year (measured here by number of males). Years having few flowers per butterfly result in a population decline the following year. In contrast, population growth is higher when many flowers are available for each butterfly. Thus, food availability (lots of Erigeron speciosus flowers) in a given year affects the number of butterflies in the following year. (Graph modified from Boggs and Inouye 2012, Ecology Letters)
Temporal and geographic description Data from two long-term studies at the Rocky Mountain Biological Laboratory, in Colorado.
Legend (figures or tables) Population growth of Mormon fritillary butterflies (Speyeria mormonia) plotted against the number of fleabane daisy (Erigeron speciosus) flowers per butterfly. Both axes are natural log scale.
