For example, the females of the lowland species glue their eggs to food plants, so hatching caterpillars will have a food source on hand. The alpine Lycaeides butterflies show unique behaviors that fit their extreme habitat. 'Problems like this one are too big to solve in the time frame of a Ph.D. Fordyce, Nice and Forister are all former students of Shapiro's, and the group has continued to collaborate after they got their doctorates. At the time, the hybrids were not recorded in the scientific literature and were 'almost entirely overlooked,' he said. The project began more than 30 years ago, when Shapiro collected the alpine species at Sonora Peak. There is no gene flow, or interbreeding, between the parent species and the hybrid. Zachariah Gompert, a graduate student at Texas State University, with James Fordyce at the University of Tennessee, Knoxville Matthew Forister at the University of Nevada, Reno Shapiro and Chris Nice at Texas State, used molecular genetics techniques to show that the hybrid alpine butterflies carry a unique mix of genes from both parental species. In between, in the harsh climate above the tree line, is a third, alpine species of Lycaeides. Lycaeides melissa butterflies live on the eastern side of the Sierra, and Lycaeides idas live to the west. This type of speciation has been shown in plants, but never in animals, he said. 'Darwin published 'On the Origin of Species' in 1859, but we are still learning about the ways new species can form,' said Arthur Shapiro, professor of evolution and ecology at UC Davis and co-author of the paper. It is the first time that this type of species formation has been shown in animals, according to the report published online Dec. High in the Sierra Nevada mountains, a new species of butterfly has emerged as a hybrid of two existing species.
