Emlen takes us outside the lab and deep into the forests and jungles where he's been studying animal weapons in nature for years, to explain the processes behind the most intriguing and curious examples of extreme animal weapons. As singular and strange as some of the weapons we encounter on these pages are, we learn that similar factors set their evolution in motion. Emlen uses these patterns to draw parallels to the way we humans develop and employ our own weapons, and have since battle began.
To survive in the wild, all animals need a natural form of defence against predators. Using their teeth, claws, horns and antlers to defend, fight and hunt, these incredibly powerful creatures do whatever it takes to stay alive. Join twelve-year-old author James Ryan as he shares a bunch of surprising, cool and occasionally gross facts with us about some of nature's most awesome animals and their built-in weapons.
Venom brings readers face to face with some of the most dangerous creatures on the planet, including jellyfish, snakes, and wasps, as it uncovers the story of venom. The book explores how venom is used for predation, defense, competition, and communication by an incredible diversity of species. It examines the unique methods that these species have evolved to create and deliver their deadly toxins. The book traces venom back to its origin in early jellyfish and sea anemones, and reveals how venoms have evolved dozens of times independently all across the animal kingdom since that time. And finally, it examines the relationships between these dangerous creatures and humans. Humans have not only learned to live with them, but also to benefit from them: scientists increasingly are harnessing the power of venom to create new drugs, treatments, and anti-venoms.
Covers more than 600 reserves in over 80 countries, includes information on how to visit these extraordinary sites, their ecological significance and some historical background.
The human race is considered the ‘Wise Creature’ and superior to other living beings, but are we really Wise compared to other living creatures? This book covers negative traits prevalent among Humans which prove detrimental to the lives of even other living beings. The book also mentions about so-called achievements made by humans, in spite of which our knowledge about the eternal soul, formation processes of life, and other mysteries shrouding the Universe remain meager. A human being is on a collision course with Mother Nature and damage to the environment has become the greatest bane of our times. Man in his endeavor to usurp the role of God should not attempt to play with Mother Nature which will lead to a cataclysm.
Mostly tiny, infinitely delicate, and short-lived, insects and their relatives—arthropods—nonetheless outnumber all their fellow creatures on earth. How lowly arthropods achieved this unlikely preeminence is a story deftly and colorfully told in this follow-up to the award-winning For Love of Insects. Part handbook, part field guide, part photo album, Secret Weapons chronicles the diverse and often astonishing defensive strategies that have allowed insects, spiders, scorpions, and other many-legged creatures not just to survive, but to thrive. In 69 chapters, each brilliantly illustrated with photographs culled from Thomas Eisner’s legendary collection, we meet a largely North American cast of arthropods—as well as a few of their kin from Australia, Europe, and Asia—and observe at firsthand the nature and extent of the defenses that lie at the root of their evolutionary success. Here are the cockroaches and termites, the carpenter ants and honeybees, and all the miniature creatures in between, deploying their sprays and venom, froth and feces, camouflage and sticky coatings. And along with a marvelous bug’s-eye view of how these secret weapons actually work, here is a close-up look at the science behind them, from taxonomy to chemical formulas, as well as an appendix with instructions for studying chemical defenses at home. Whether dipped into here and there or read cover-to-cover, Secret Weapons will prove invaluable to hands-on researchers and amateur naturalists alike, and will captivate any reader for whom nature is a source of wonder.
This powerful book provides the first comprehensive overview of the intellectual roots of the worldwide environmental movement - from ancient religions and philosophies to modern science and ethics - and synthesizes them into a new philosophy of nature in which to ground our moral values and social action. It traces the origins and evolution of the dominant worldview that has built our industrial, technocratic, man-centered civilization, and brought us to the current ecological crisis. At the same time, it uncovers an alternative cultural tradition in the world's different religions and philosophies and describes how these ideas are now surfacing and coalescing to form an ecological sensibility and a new vision of nature which recognizes the inter-relatedness of all living things. Finally, this book integrates these varied traditions with modern physics and the science of ecology into a larger philosophical whole that provides the environmental movement with a comprehensive vision of an organic and sustainable society in harmony with nature. As ecological disasters continue to threaten our planet, becoming worse with every passing moment of indifference, it has become clear that we must take action. We must change our relationship with nature, and return to the days when our lives were intimately connected to and dependent upon the natural world. Nature's Web lays the foundations for that change by explaining where our complex ideas about nature come from, why they are wrong, and what we can do to change them.
The Serengeti is one of the world's most renowned ecosystems, and at its apex prowls the Serengeti Lion. These majestic mammals are iconic, and integral, and also in constant danger from encroaching humans. Craig Packer is among the unique species that has spent a lifetime ensuring the study and perpetuity of these dark maned cats. He has dedicated countless research hours and dollars to the coexistence of humans and wildlife in the Serengeti. He has even proposed ways of using lion hunting to ensure their value, and hence their protection. "Lions in the Balance "takes us into the red-in-tooth-and-claw world of lion conservation. It is an incredibly candid, entertaining, and at points alarming look at what the future of the Serengeti lions entails, and how the politics of conservation require survival strategies far more creative and powerful than what animals (humans included) on the savannas must possess. A sequel to Mr. Packer's "Into Africa, "this diary based chronicle of the past decade draws readers along the dusty trails and into the spectacular sunsets of the Serengeti. Through his experiences we learn that female lions prefer their male manes dark and long, that lion attacks on humans most commonly occur during the full moon cycles, and that citizen science is shaping the world--Packer's initiative Snapshot Serengeti has helped engage globally, and locally, and has identified thousands of images of the Serengeti. The narrative moves from Arusha to the Serengeti to Washington DC, and with some temporal hopping, as often the stories are as rich and multilayered as the Serengeti ecosystem. And Mr. Packer demonstrates that he possesses himself a bit of cat, having needed nearly nine lives to persist in the ever dynamic and vexed world of conservation in Africa.
North East India is called nature’s gift to India. It is mountainous, thickly forested, nourished by massive rainfall, has massive rivers, has a diverse wildlife, inhabited a number of forest dwellers called tribes who cherished environmentalist ethos. The region has been experiencing environmental depletion which was a result of colonial policies, exploitation of its ecological and mineral resources, large scale trans-border immigration and settlement of people, establishment of the plantation industry through deforestation and the dependence of the dairy industry on grazing and other factors. This books depicts the precariousness of the environmental situation and traces the history and politics of such degeneration with a view to raise the consciousness of the people of the region towards their environment and save it from further aggravation.
