In addition, the evolution of plants and animals, especially mammals and dinosaurs, is well preserved in the region, which also has among the best records of the origin of modern man. The Story of Earth and Life provides a fascinating insight into this remarkable history - how southern Africa's mineral deposits were formed, how its life evolved and how its landscape was shaped. Along the way readers will be enthralled by accounts of the Big Bang that marked the beginning of time and matter, by drifting and colliding continents, folding and fracturing rocks, meteors colliding with the Earth, volcanic eruptions, and the start of life. Other topics include why South Africa is so rich in minerals, how glacial deposits came to be found in the Karoo, why dinosaurs became extinct, how mammals developed from reptiles, and how closely humans are related to the apes. The answers to many such questions can be found here.

Yet Pulitzer Prize-winning author Annie Dillard avers Moby-Dick is the \"best book ever written about nature,\" and nearly the entirety of the story is set on the waves, with scarcely a whiff of land. In fact, Ishmael's sea yarn is in conversation with the nature writing of Emerson and Thoreau, and Melville himself did far more than live for a year in a cabin beside a pond. He set sail: to the far remote Pacific Ocean, spending more than three years at sea before writing his masterpiece in 1851.\u003cbr\u003e\u003cbr\u003eA revelation for Moby-Dick devotees and neophytes alike, Ahab's Rolling Sea is a chronological journey through the natural history of Melville's novel. From white whales to whale intelligence, giant squids, barnacles, albatross, and sharks, Richard J. King examines what Melville knew from his own experiences and the sources available to a reader in the mid-1800s, exploring how and why Melville might have twisted what was known to serve his fiction. King then climbs to the crow's nest, setting Melville in the context of the American perception of the ocean in 1851--at the very start of the Industrial Revolution and just before the publication of On the Origin of Species. King compares Ahab's and Ishmael's worldviews to how we see the ocean today: an expanse still immortal and sublime, but also in crisis. And although the concept of stewardship of the sea would have been entirely foreign, if not absurd, to Melville, King argues that Melville's narrator Ishmael reveals his own tendencies toward what we would now call environmentalism.\u003cbr\u003e\u003cbr\u003eFeaturing a coffer of illustrations and an array of interviews with contemporary scientists, fishers, and whale watch operators, Ahab's Rolling Sea offers new insight not only into a cherished masterwork and its author but also into our evolving relationship with the briny deep--from whale hunters to climate refugees.\u003c\/p\u003e","brand":"I H Pentz Booksellers","offers":[{"title":"Default Title","offer_id":40011421909154,"sku":"","price":860.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0364\/4047\/3732\/products\/9780226514963.jpg?v=1623071768"},{"product_id":"9780521269322","title":"Biophysics and Biochemistry at Low Temperatures by Franks, Felix","description":"\u003cp\u003eISBN: 9780521269322\u003c\/p\u003e\n\u003cp\u003eCAMBRIDGE UNIVERSITY PRESS | 19 Jul 2012\u003c\/p\u003e\n\u003cp\u003ePaperback 222 Description\u003c\/p\u003e\n\u003cp\u003eCold is the single most important enemy of life, and this book, first published in 1985, discusses the responses of living organisms to low temperatures.

The prevailing methodology, which claims causality from measures of statistical significance, is inductive and yields contradictory results. In this book, instead of correlations, Isabelle Tsakok looks for patterns common to cases of successful agricultural transformation and then tests them against other cases. She proposes a hypothesis that five sets of conditions are necessary to achieve success. She concludes that government investment in and delivery of public goods and services sustained over decades is essential to maintaining these conditions and thus successfully transform poverty-ridden agricultures. No amount of foreign aid can substitute for such sustained government commitment.

This book traces in detail a broad variety of such 'Anthropocene encounters': in science, philosophy and literary fiction. It asks what it means to 'think green' in a time when nature no longer offers a stable backdrop to political analysis. Do familiar political categories and concepts, such as democracy, justice, power and time, hold when confronted with a world radically transformed by humans? The book responds by inviting more radical political thought, plural forms of engagement, and extended ethical commitments, making it a fascinating and timely volume for graduate students and researchers working in earth system governance, environmental politics and studies of the Anthropocene.

The need to adopt a novel approach arose because the existing practice of agricultural extension did not meet the needs of the farming community there, and the funding bodies were dissatisfied with the return on their investment. The way in which the relationship between the rural community and researchers might be differently, and perhaps more fruitfully, managed are discussed. The issues addressed have relevance in a wider context and, as a result, this book will be of importance to any professional involved in agricultural management and policy making.\u003c\/p\u003e","brand":"IH Pentz Booksellers","offers":[{"title":"Default Title","offer_id":41889360478370,"sku":"","price":200.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0364\/4047\/3732\/products\/9780521039413.jpg?v=1668171297"},{"product_id":"9781868123735","title":"Wild Ways: A Field Guide to Mammal Behavior in Southern Africa :  by Apps, Peter","description":"\u003cp\u003eISBN: \"9781868123735\u003c\/p\u003e\n\u003cp\u003eSouthern Book Publishers \u003cspan data-mce-fragment=\"1\"\u003e01 March 1998\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003ePaperback 198 pages Book by Apps, Peter\u003c\/p\u003e\n\u003cp\u003eSouthern Africa has one of the richest and most accessible mammal fauna in the world.

Indeed anyone interested in birds will study their nests and habitats. In this handsome book the author describes the varied kinds of nests and their construction: from simple nests of twigs to the complicated woven nests stitched by the tailor-bird. Illustrated throughout in color and black-and-white, we see the \"traditional\" cup-shaped nests of straw, mud nests, hanging nests, enclosed or domed nests, even the edible nests which produce the rare and expensive - but tasteless - birds’ nest soup. \"Birds as Builders\" tells us how some birds build vast structures, many times their own weight, on the ground and how others nest in colonies, cooperative communities and even communes. Some species make nests but do not rear their young, others build no nest but raise their brood conscientiously, and still others neither build nests nor care for their eggs - the parasites, like the cuckoo, for instance, who rely on \"host\" birds to do the work.

Using a combination of historical analyses, theoretical models and case studies, with explicit links to invasion biology, the authors cover biological control of insects, weeds, plant pathogens and vertebrate animals. The book reflects increasing recognition of risks over the past 20 years, and incorporates the latest technological advances and theoretical developments. It is ideal for researchers and students of biological control and invasion biology.\u003c\/p\u003e","brand":"I H Pentz Booksellers","offers":[{"title":"Default Title","offer_id":42740386365602,"sku":"","price":800.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0364\/4047\/3732\/products\/9780521845144.jpg?v=1666014206"},{"product_id":"9780521532037","title":"People and Wildlife, Conflict or Co-existence? by Woodroffe, Rosie","description":"\u003cp\u003eISBN: 9780521532037\u003c\/p\u003e\n\u003cp\u003eCambridge University Press, 31 July 2008\u003c\/p\u003e\n\u003cp\u003ePaperback, 516 pages\u003c\/p\u003e\n\u003cp\u003eDescription\u003c\/p\u003e\n\u003cp\u003eHuman-wildlife conflict is a major issue in conservation. As people encroach into natural habitats, and as conservation efforts restore wildlife to areas where they may have been absent for generations, contact between people and wild animals is growing. Some species, even the beautiful and endangered, can have serious impacts on human lives and livelihoods. Tigers kill people, elephants destroy crops and African wild dogs devastate sheep herds left unattended. Historically, people have responded to these threats by killing wildlife wherever possible, and this has led to the endangerment of many species that are difficult neighbours. The urgent need to conserve such species, however, demands coexistence of people and endangered wildlife. This book presents a variety of solutions to human-wildlife conflicts, including novel and traditional farming practices, offsetting the costs of wildlife damage through hunting and tourism, and the development of local and national policies.\u003c\/p\u003e","brand":"I H Pentz Booksellers","offers":[{"title":"Default Title","offer_id":42769879302306,"sku":"","price":350.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0364\/4047\/3732\/products\/9780521532037.jpg?v=1666869745"},{"product_id":"9781108821575","title":"There Is No Planet B by Berners-Lee, Mike","description":"\u003cp\u003eISBN: 9781108821575\u003c\/p\u003e\n\u003cp\u003eCambridge University Press, 01 January 2021\u003c\/p\u003e\n\u003cp\u003ePaperback, 336 pages\u003c\/p\u003e\n\u003cp\u003eFeeding the world, climate change, biodiversity, antibiotics, plastics, pandemics - the list of concerns seems endless.

When entering the field over a decade ago, many young primatologists were driven by evolutionary questions centered in behavioural ecology. However, given the current environment of cascading extinctions and increasing threats to primates we now need to ensure that primates remain in viable populations in the wild before we can simply engage in research in the context of pure behavioural ecology. This has changed the primary research aims of many primatologists and shifted our focus to conservation priorities, such as understanding the impacts of human activity, habitat conversion or climate change on primates. This book presents personal narratives alongside empirical research results and discussions of strategies used to stem the tide of extinction.
