New study shows warmer temperatures and increases during the summer are compensating for negative factors, stabilizing breeding trends Largely because of well-publicized, diminishing winter colonies in Mexico and California, monarch butterflies across North America have been long thought to be declining as a result of diminishing summer habitat. Previous butterfly research shows that the size of overwintering monarch colonies has fallen across several decades. But what is happening when monarchs breed in the summer was less clear. In a new research study published in Global Change Biology, lead author Michael Crossley, assistant professor and agricultural entomologist at the University of Delaware, and his collaborators examined trends in breeding monarchs across their entire range,...
