Sex-specific ornament evolution is a consistent feature of climatic adaptation across space and time in dragonflies

July 2021
Michael P. Moore, Kaitlyn Hersch, Chanont Sricharoen, Sarah Lee, Caitlin Reice, Paul Rice, Sophie Kronick, Kim A. Medley, and Kasey D. Fowler-Finn.
Proceedings of the National Academy of Sciences
Dragonflies consistently adapt to warmer climates across space and time by evolving less male melanin ornamentation—a mating-related trait that also absorbs solar radiation and heats individuals above ambient temperatures.Read More →
