Download or read book Threat to the Yangtze River Dolphin written by Amie Jane Leavitt and published by Mitchell Lane. This book was released on 2020-02-04 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yangtze River dolphins, also known as Baiji, have splashed in the waters of Chinas Yangtze River for millions of years. The Chinese people have always loved these mammals. They considered the Baiji to be a beautiful part of their river, and they have told many stories about them. Today, the Yangtze is a very different place. Trash floats in the water, and toxic chemicals pollute it. Thousands of boats travel up and down the river every day, and people use dangerous fishing equipment with sharp rolling hooks. The Yangtze River is no longer a safe place for the Baiji to live. Most of them have died out. Scientists worry that it might be too late for these dolphins. Is there any way to save them?
Download or read book Witness to Extinction written by Samuel Turvey and published by OUP Oxford. This book was released on 2009-08-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tragic recognition of the extinction of the Yangtze River Dolphin or baiji in 2007 became a major news story and sent shockwaves around the world. It made a romantic story, for the baiji was a unique and beautiful creature that features in many Chinese legends and folk tales. The Goddess of the Yangtze, as it was known, was also the lone representative of an entire and ancient branch of the Tree of Life. But perhaps the greater tragedy is that its status as one of the world's most threatened mammals had been widely recognized, yet despite wide publicity virtually no international funds became available. A compelling read by a young naturalist, Samuel Turvey tells the story of the plight of the Yangtze River Dolphin from his unique perspective as a conservation biologist deeply involved in the struggle to save the dolphin. This is both a celebration of a beautiful and remarkable animal that once graced one of China's greatest rivers, its natural history and its role as a cultural symbol; and also a personal, eyewitness account of the failures of policy and the struggle to get funds that led to its tragic demise. It is a true cautionary tale that we must learn from, for there are countless other threatened species that will suffer from the same human mistakes, and whose loss we shall not know until it is too late.

Download or read book Biosonar written by Annemarie Surlykke and published by Springer. This book was released on 2014-07-19 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two groups of animals, bats and odontocetes (toothed whales), have independently developed the ability to orient and detect prey by biosonar (echolocation). This active mechanism of orientation allows these animals to operate under low light conditions. Biosonar is a conceptual overview of what is known about biosonar in bats and odontocetes. Chapters are written by bat and odontocetes experts, resulting in collaborations that not only examine data on both animals, but also compare and contrast mechanisms. This book provides a unique insight that will help improve our understanding of biosonar in both animal groups.

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Download or read book Threat to the Bengal Tiger written by Claire O'Neal and published by Mitchell Lane. This book was released on 2020-02-04 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before the 1900s, hundreds of thousands of wild tigers roamed Southeast Asia. Their beauty, fierceness, and intelligence inspired fear and awe in their human neighbors. These peoples gave the tiger starring roles in folktales and mythology. Human fascination with tigers continues. Unfortunately, the tiger may not survive in the wild much longer. Researchers estimate that fewer than 2,500 tigers remain in their natural habitat. As the human population explodes in Southeast Asia, the wild tiger population pays the price. Can the wild tiger be saved by its only natural enemy, people?

Download or read book 100 Butterflies and Moths written by Jeffrey C. Miller and published by Harvard University Press. This book was released on 2007 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walking a forest trail in Costa Rica, a visitor might be struck by the sight of an iridescent blue morpho butterfly fluttering ahead in the filtered daylight, or an enormous silk moth, as magnificently patterned and subtly colored as a Persian carpet, only emerging to fly at night. Elsewhere, vivid yellow and orange sulphur butterflies flock to puddles to sip the concentrated minerals. Such is the dazzling variety of the butterflies and moths unique to this region. Gathered by biologists Daniel Janzen and Winifred Hallwachs in the forests of northwestern Costa Rica, 100 tropical butterflies and moths represent the diversity in large-format photographs by Jeffrey Miller that document the dizzying variety of shapes, colors, and markings. The photographs are accompanied by species accounts and images of the corresponding caterpillar. The authors recount these insects' feats of mimicry and migration, lift the veil on their courtship, and show how the new technology of DNA barcoding is changing the picture of Lepidopteran biodiversity. The authors also tell the success story of Area de Conservacion Guanacaste, where the long-term work of Janzen and Hallwachs, a team of caterpillar collectors, and the participation of neighboring farming communities has deepened understanding of Costa Rica's Lepidoptera and has brought about advances in restoration ecology of tropical habitats, biodiversity prospecting, biotechnology, and ecotourism development.

Download or read book Ethology and Behavioral Ecology of Odontocetes written by Bernd Würsig and published by Springer. This book was released on 2019-08-02 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.
Download or read book 100 Animals written by Nick Garbutt and published by Bradt Travel Guides. This book was released on 2007 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 100 Animals to See Before They Die is inspired by the Zoological Society of London's recently launched conservation project EDGE - Evolutionarily Distinct and Globally Endangered. EDGE targets some of the world's most bizarre and unusual creatures, animals which are extremely distinct in the way they look, live and behave. They have few or no close relatives and require immediate action to save them from extinction. If they disappear there will be nothing like them left on the planet. Amazingly, many of these species are ignored by existing conservation plans. 100 Animals fights this ignorance by highlighting the danger these species are in and will encourage greater involvement in the fight to save them. Some EDGE species, such as tigers, elephants and pandas are well known, but 100 Animals features dozens of lesser known and extraordinary animals such as the Yangtze River Dolphin (the world's rarest cetacean), the Bumblebee Bat (the smallest mammal on earth) and the egg-laying Long-beaked Echidna. Organised by world regions (Eurasia, Australasia, Africa, New World, South East Asia, the Oceans) and with a whole section devoted to Madagascar, 100 Animals is inspirational and packed with information about each animal and where to find it. Each animal is illustrated in colour and accompanied by a distribution map and information about its key characteristics and the specific threats it faces, plus details about any conservation work taking place.
