Review of Monarchs and Milkweed: A Migrating Butterfly, a Poisonous Plant, and Their Remarkable Story of Coevolution by Agrawal Anurag
Notice bibliographique
Résumé
During my final year of graduate study at Northern Michigan University, several of my naturalist friends and I decided to take a long weekend, despite our need to continue writing our master's theses.we loaded up all of our plant presses, field guides, nets, collecting jars, binoculars, and spotting scopes and headed down to Peninsula Point in Delta County, Michigan.It was a beautiful fall day and we arrived early in the morning in order to get a glimpse of any birds making their way from Canada to their overwintering spots in the neotropics.However, the real stars of the show turned out to be the thousands of monarch butterflies that had gathered for their own continental migration.This natural spectacle sparked in me my love of Lepidoptera and eventually set me on a course of studying plant-herbivore interactions when I started a PhD about a year later.Dr. Anurag Agrawal's new book has in no doubt been influenced by the hundreds of naturalists like myself who are entranced by the wonders of monarch biology.Dr. Agrawal, with years of studies under his belt, is one of the top plantherbivore biologists in the world.Carefully tracing the life history of the monarch along its spring migration from Mexico to southern Canada and back again in the autumn, Dr. Agrawal weaves in classic studies, including past monarch research by the Urquharts and Lincoln Brower as well as insights from his own years of studying monarch caterpillars and milkweeds.Dr. Agrawal's personal insight is what makes this book unique.Sandwiched between accounts of spring and fall monarch migration (which make up the first and last chapters of the book), are chapters in which Dr. Agrawal draws deeply from his expertise on plant-insect interactions.The discussion of the biology of milkweeds, and particularly their defense traits, is not only interesting in itself, but also provides a great general discussion on how chemistry and biology conspire to create the wonderful co-evolutionary study of monarchs and milkweeds.Dr. Agrawal makes it clear that this story isn't just about monarchs, but also about the diverse genus that contains milkweed.Here he discusses several species of the milkweed genus (Asclepias) and the various ways milkweeds have evolved to defend themselves from herbivore attack through chemical defenses and physical defenses.Dr. Agrawal shows that these defense traits vary among the roughly 140 species of milkweeds; for example, some relying heavily on chemicals to defend themselves, whereas others don't bother to produce as many chemicals and instead stick to trichomes for defense.The discussion of milkweed diversity, however, is primarily framed as being a problem for monarchs to solve.The rich research history on the common milkweed (Asclepias syriaca) is
