    But what were and are the true potentates of our planet? Insects, says Scott Richard Shaw—millions and millions of insect species. Starting in the shallow oceans of ancient Earth and ending in the far reaches of outer space—where, Shaw proposes, insect-like aliens may have achieved similar preeminence—Planet of the Bugs spins a sweeping account of insects’ evolution from humble arthropod ancestors into the bugs we know and love (or fear and hate) today. Leaving no stone unturned, Shaw explores how evolutionary innovations such as small body size, wings, metamorphosis, and parasitic behavior have enabled insects to disperse widely, occupy increasingly narrow niches, and survive global catastrophes in their rise to dominance. Through buggy tales by turns bizarre and comical—from caddisflies that construct portable houses or weave silken aquatic nets to trap floating debris, to parasitic wasp larvae that develop in the blood of host insects and, by storing waste products in their rear ends, are able to postpone defecation until after they emerge—he not only unearths how changes in our planet’s geology, flora, and fauna contributed to insects’ success, but also how, in return, insects came to shape terrestrial ecosystems and amplify biodiversity. Indeed, in his visits to hyperdiverse rain forests to highlight the current insect extinction crisis, Shaw reaffirms just how crucial these tiny beings are to planetary health and human survival. In this age of honeybee die-offs and bedbugs hitching rides in the spines of library books, Planet of the Bugs charms with humor, affection, and insight into the world’s six-legged creatures, revealing an essential importance that resonates across time and space.

    But these tiny insects, once merely a seasonal annoyance, now are capturing headlines worldwide as new information emerges about the diseases they carry, their migratory population, and their growing resistance to pesticides.Harvard professor Andrew Spielman has dedicated his life to understanding this insect, a passion that makes him the perfect guide to their amazing world and the perfect author of this lively, accessible book that offers an intriguing and horrifying mosquito-eye view of nature and man. He explains where mosquitoes breed, and how they die, showing us their natural foes and man-made enemies while explaining the myriad diseases they bring to all corners of the world. Spielman offers colorful examples of how the mosquito has insinuated itself into human history, from the defeat of Sir Francis Drake's fleet to the death of thousands of Frenchmen working on the Panama Canal to the recent widespread West Nile panic in New York City. Filled with little-known facts and illuminating anecdotes that bring this tiny being into larger focus, Mosquito offers fascinating, alarming, and convincing evidence that the sooner we get to know this little creature, the better off we'll be.

    Since reptiles are cold-blooded creatures, most humans don't instinctively understand their requirements the way they understand the needs of a cat or dog. Herp expert Philippe de Vosjoli and his team of veterinarians and authors seek to make keepers confident in their ability to properly care for their bearded dragons through this most informative book. A key component of caring for bearded dragons, according to the authors, is recognizing that their needs change as they develop. De Vosjoli states in the introduction to the book, "Looking at the life stages of bearded dragons also made [the authors] aware that, like humans, they undergo changes in growth and behavior, which may require the dedicated owner to make adjustments in husbandry (and general care) to meet the needs of each life style." The Bearded Dragon Manual is the first book to present this information that is so critical to the proper maintenance of these very popular reptiles.Colorfully illustrated, The Bearded Dragon Manual provides chapter-length coverage on the following topics: selecting a dragon, making a home for a dragon, heating and lighting, diet and feeding management, and behavior. The feeding chapter, which includes as age-by-age guide to nutrition, was co-written with veterinarian Dr. Susan Donoghue. A chapter on breeding discusses strategies for breeding dragons, requirements, conditioning, incubation, and potential problems encountered. Lizard vet extraordinaire Dr. Roger Klingenberg has written a chapter on recognizing and treating bearded dragon diseases, in which he discusses how to recognize a sick dragon, various internal and external parasites, nutritional disorders as well as kidney disease, prolapses, egg-binding, respiratory infections, and eye problems. The chapter concludes with a four-page chart for troubleshooting health problems. Herb expert Jerry Cole has provided a special chapter on frilled dragons, an agamid similar to the bearded dragon that has attracted many bearded dragon fans. Appendices and index included.

    But it was not reels of wool or bales of cotton that awaited him, but plants and seeds…Over the next forty years, Bartram would send hundreds of American species to England, where Collinson was one of a handful of men who would foster a national obsession and change the gardens of Britain forever, introducing lustrous evergreens, fiery autumn foliage and colourful shrubs. They were men of wealth and taste but also of knowledge and experience like Philip Miller, author of the bestselling Gardeners Dictionary, and the Swede Carl Linnaeus, whose standardised botanical nomenclature popularised botany as a genteel pastime for the middle-classes; and the botanist-adventurer Joseph Banks and his colleague Daniel Solander who both explored the strange flora of Tahiti and Australia on the greatest voyage of discovery of modern times, Captain Cook’s Endeavour.This is the story of these men – friends, rivals, enemies, united by a passion for plants – whose correspondence, collaborations and squabbles make for a riveting human tale which is set against the backdrop of the emerging empire, the uncharted world beyond and London as the capital of science. From the scent of the exotic blooms in Tahiti and Botany Bay to the gardens at Chelsea and Kew, and from the sounds and colours of the streets of the City to the staggering vistas of the Appalachian mountains, The Brother Gardeners tells the story of how Britain became a nation of gardeners.

    To love and loathe the fox is a British condition."The fox is our apex predator, our most beautiful and clever killer.

And yet we long to stroke the tumbling cubs outside their tunnel homes and watch the vixen stalk the cornfield.There is something about foxes. They captivate us like no other species.Exploring a long and sometimes complicated relationship, The Wild Life of the Fox captures our love – and sometimes loathing – of this magnificent creature in vivid detail and lyrical prose.
