The attention-grabbing and intricate evolutionary dating of the monarch butterfly and the milkweed plant
Monarch butterflies are one in all nature's such a lot recognizable creatures, recognized for his or her vibrant shades and epic annual migration from the U.S. and Canada to Mexico. but there's even more to the monarch than its unique presence and mythic touring. In Monarchs and Milkweed, Anurag Agrawal offers a bright research into how the monarch butterfly has developed heavily along the milkweed—a poisonous plant named for the sticky white substance emitted whilst its leaves are damaged—and how this inextricable and intimate dating has been like an fingers race over the millennia, a conflict of exploitation and protection among interesting species.
The monarch existence cycle starts off every one spring while it deposits eggs on milkweed leaves. yet this dependency of monarchs on milkweeds as nutrients isn't reciprocated, and milkweeds do all they could to poison or thwart the younger monarchs. Agrawal delves into significant medical discoveries, together with his personal pioneering study, and strains how plant poisons haven't purely formed monarch-milkweed interactions yet have additionally been culturally very important for hundreds of years. Agrawal provides present rules concerning the contemporary decline in monarch populations, together with habitat destruction, elevated iciness storms, and absence of milkweed—the final one a concept that the writer rejects. He evaluates the present sustainability of monarchs and divulges a singular reason for their plummeting numbers.
Lavishly illustrated with greater than 80 colour images and pictures, Monarchs and Milkweed takes readers on an unforgettable exploration of 1 of nature's most vital and complicated evolutionary relationships.
