Monarchs In A Changing World

Monarch butterflies are among the most popular insect species in the world and are an icon for conservation groups and environmental education programs. Monarch caterpillars and adults are easily recognizable as welcome visitors to gardens in North America and beyond, and their spectacular migration in eastern North America (from breeding locations in Canada and the United States to overwintering sites in Mexico) has captured the imagination of the public. Monarch migration, behavior, and chemical ecology have been studied for decades. Yet many aspects of monarch biology have come to light in only the past few years. These aspects include questions regarding large-scale trends in monarch population sizes, monarch interactions with pathogens and insect predators, and monarch molecular genetics and large-scale evolution. A growing number of current research findings build on the observations of citizen scientists, who monitor monarch migration, reproduction, survival, and disease. Monarchs face new threats from humans as they navigate a changing landscape marked by deforestation, pesticides, genetically modified crops, and a changing climate, all of which place the future of monarchs and their amazing migration in peril. To meet the demand for a timely synthesis of monarch biology, conservation and outreach, Monarchs in a Changing World summarizes recent developments in scientific research, highlights challenges and responses to threats to monarch conservation, and showcases the many ways that monarchs are used in citizen science programs, outreach, and education. It examines issues pertaining to the eastern and western North American migratory populations, as well as to monarchs in South America, the Pacific and Caribbean Islands, and Europe. The target audience includes entomologists, population biologists, conservation policymakers, and K–12 teachers.

Monarch Butterflies is a richly illustrated, large-format book that celebrates North America’s most recognized butterfly and educates children and families about what they can do to help protect these beloved pollinators from the impacts of habitat loss and climate change.

Synthesizes current scientific knowledge on the life cycle, behavior, spectacular migration, and conservation of this charismatic insect.

The British monarchy has long been a subject of fascination for many people. Television shows and films have been created to tell the history of influential, long-reigning monarchs such as Queen Elizabeth II, and royal weddings are televised worldwide. This engaging look at British history examines past and present monarchs, how marriages such as the one between Prince Harry and Meghan Markle broke tradition, and the controversy over whether or not Britain needs a monarchy. Through sidebars, annotated quotations, maps, and full-color photographs, readers will gain a deeper understanding of this popular historical topic.

A ten-year-old girl may be the only person who can save humanity from extinction in this exciting graphic novel adventure. It’s been fifty years since a sun shift wiped out nearly all mammal life across the earth. Towns and cities are abandoned relics, autonomous machines maintain roadways, and the world is slowly being reclaimed by nature. Isolated pockets of survivors keep to themselves in underground sites, hiding from the lethal sunlight by day and coming above ground at night. 10-year-old Elvie and her caretaker, Flora, a biologist, are the only two humans who can survive during daylight because Flora made an incredible discovery – a way to make an antidote to sun sickness using the scales from monarch butterfly wings. Unfortunately, it can only be made in small quantities and has a short shelf life. Free to travel during the day, Elvie and Flora follow monarchs as they migrate across the former Western United States, constantly making new medicine for themselves while trying to find a way to make a vaccine they can share with everyone. Will they discover a way to go from a treatment to a cure and preserve what remains of humanity, or will their efforts be thwarted by disaster and the very people they are trying to save? Little Monarchs is a new kind of graphic novel adventure—one that invites readers to take an intimate look at the natural world and the secrets hidden within. Elvie and Flora’s adventures take place in real locations marked panel-by-panel with coordinates and a compass heading. Curious readers can follow their travel routes and see the same landscapes—whether it be a secluded butterfly grove on the California coast or a hot-springs in the high desert. Through both comic narrative and journal entries, readers learn the basics of star navigation, how to tie useful knots, and other survival skills applicable in the natural world. Creator Jonathan Case acquired the fact-based portion of Little Monarchs through intensive research and several expeditions to study monarchs across the western United States. Scientific support also came from the Xerces Society, the world leaders in monarch preservation.

Why are monarch butterflies disappearing? Scientists are racing to find answers. These iconic orange, black, and white butterflies flutter across much of the North American continent, and are a familiar summer sight in many backyards. But in the last twenty years, the monarch butterfly population has been decreasing. Why? Skilled science writer Rebecca E. Hirsch takes readers on a quest to discover what scientists already know—and what they're hoping to learn. In addition, she offers tips about what monarch lovers can do to make a difference, from planting a butterfly garden to getting the word out about harmful pesticides to taking part in citizen science projects.

The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant Monarch butterflies are one of nature's most recognizable creatures, known for their bright colors and epic annual migration from the United States and Canada to Mexico. Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed—a toxic plant named for the sticky white substance emitted when its leaves are damaged—and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species. The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed—the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers. Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.

Although no one had ever followed North American monarch butterflies on their annual southward journey to Mexico and California, in the 1990s there were well-accepted assumptions about the nature and form of the migration. But to Robert Michael Pyle, a naturalist with long experience in monarch conservation, the received wisdom about the butterflies’ long journey just didn’t make sense. In the autumn of 1996 he set out to uncover the facts, to pursue the tide of “cinnamon sailors” on their long, mysterious flight. Chasing Monarchs chronicles Pyle’s 9,000-mile journey to discover firsthand the secrets of the monarchs’ annual migration. Part road trip, part outdoor adventure, and part natural history study, Pyle’s book overturns old theories and provides insights both large and small regarding monarch butterflies, their biology, and their spectacular migratory travels. Since the book’s first publication, its controversial conclusions have been fully confirmed, and monarchs are better understood than ever before. The Afterword for this volume includes not only updated information on the myriad threats to monarch butterflies, but also various efforts under way to ensure the future of the world’s most amazing butterfly migration.
