Monarchs and Milkweed - A Migrating Butterfly a Poisonous Plant and Their Remarkable Story of Coevolution

Anurag Agrawal

Summary

The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plantMonarch 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.

Patient Care

MD Paul Seward

Recalling remarkable cases-and people-from a career launched in the first days of Emergency Medicine, Dr. Paul Seward leads us in his memoir through suspenseful diagnoses and explorations of anatomy. By his side, we learn to distinguish nursemaid's elbow from a true broken arm. We learn how our breathing and swallowing mechanisms resemble a practical joke. But when a baby's heart stops and a young doctor forgets what to do, the situation is far from funny. Within the conditions of great stress and rapid decision-making that are routine in the ER, Dr. Seward shows us that medical staff must be more than technicians of the body: they must be restorers of the human. Whether it is comforting anxious families or subjecting a distressed patient to tough procedures, they must learn the difficult work of caring for strangers. Throughout Patient Care, Dr. Seward reflects on how a life in medicine tests what it means to put ethics into practice.

Peaceful Breeze

Mark Carrington

Caring for someone you love who is suffering from a terminal illness can be one of the greatest honours in life. Helping a loved one to die with peace, grace and dignity is their human right and a privilege for their carer to enable. It can be a truly transformative experience.

In Peaceful Breeze Mark Carrington shares his searingly honest account of nursing his much-loved mother after she was diagnosed with bowel cancer in 2014.

As his mum's son, carer and advocate, Mark felt alone and under tremendous pressure to look after her the best he could; at the time, he wished that there was a practical guide to support him as he was supporting his mum.

Peaceful Breeze is Mark's profound journey through terminal illness; from his mum's initial diagnoses, through her valiant fight, to her ultimate passing. He charts the emotional turmoil - from complete despair to moments of joy with his mum that will live on forever - the stress, the difficult decisions he had to make and finally the all-consuming grief he experienced at her loss.

Mark Carrington story is one of bravery, devotion, love and hope, one which he hopes will support and inform other carers as they nurse and cherish their own family and friends.

London Transport's Last Buses -...

Matthew Wharmby

The Olympian was Leyland's answer to the competition that was threatening to take custom away from its second-generation OMO double-deck products. Simpler than the London Transportcentric Titan but, unlike that integral model, able to respond to the market by being offered as a chassis for bodying by the bodybuilder of the customer's choice, the Olympian was an immediate success and soon replaced both the Atlantean and Bristol VRT as the standard double-decker of the NBC. It wasn't until 1984 that London Transport itself dabbled with the model, taking three for evaluation alongside trios of contemporary double-deckers.The resulting L class spawned an order for 260 more in 1986, featuring accessibility advancements developed by LT in concert with the Ogle design consultancy, but the rapid changes engulfing the organisation meant that no more were ordered. During the 1990s company ownerships shifted repeatedly as the ethos of competition gave way to the cold reality of big business, an unstable situation which even saw London's bus operations broken up.The L class was split between three new companies, but the backlog of older vehicles to replace once corporate interests released funding ensured the buses up to a further decade in service. Finally, as low-floor buses swept into the capital at the turn of the century, Olympian operation at last declined, and the final examples operated early in 2006.This profusely illustrated book describes the diversity of liveries, ownerships and deployments that characterised the London Leyland Olympians' two decades of service.
