Variation in Forewing Size Linked to Migratory Status in Monarch Butterflies

Long-distance migration can be seen throughout the animal kingdom and can have large impacts on population dynamics and species distributions. The act of migration itself also affects the evolution of a species, as evolutionary forces select for certain characteristics in animals conducting long-dis...
