View Resource Effects of frost on wildflowers: an unexpected consequence of climate change [resource group]

A collection of slides about the effects of frost on Colorado wildflowers at the Rocky Mountain Biological Laboratory (RMBL). RMBL is a high-altitude field research station at 9,500 feet in the Colorado Rocky Mountains. RMBL has supported field work since it was founded in 1928, and is the location of the research described in this slide show.

An example of a late spring frost and snow event at the Rocky Mountain Biological Laboratory (RMBL), at 9,500 feet in the Colorado Rocky Mountains. This photograph was taken on 13 June 2001, when the temperature went down to 21.5 F, (-5.8 C). This cold period killed flower buds of several wildflower species that had already produced leaves and buds.

A graph (modified from Boggs and Inouye 2012, Ecology Letters) demonstrating that Speyeria mormonia (Mormon fritillary) butterfly visits are proportionally greater when their food plant, Erigeron (fleabane), produces many flowers. Frost damage reduces the number of available flowers. When flowers are abundant, they produce more nectar and attract more butterflies. In turn, the greater...

Delphinium barbeyi, or tall larkspur, flowering in a year with no frost damage. Photographed (by David Inouye) in front of Gothic Mountain, at the Rocky Mountain Biological Laboratory. Altitude about 9,500 ft (2,900m).

A Mormon fritillary butterfly (Speyeria mormonia) visiting flowers of the fleabane daisy (Erigeron speciosus), an important and preferred nectar resource. Flower buds of E. speciosus are frost-sensitive. Egg production of female S. mormonia butterflies is limited by the amount of nectar they can collect (which is unusual for butterflies). Therefore, spring frosts that kill E. speciosus flowers...
