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 36 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?

Available in PDF, EPUB and Kindle. Book excerpt: "The baiji/Chinese river Dolphin/Yangtze River Dolphin (Lipotes vexillifer) was listed as endangered under the Endangered Species Act (ESA) in 1989. The Office of Protected Resources, National Marine Fisheries Service has completed a 5-year of the status of the species. A 5-year review is a periodic analysis of a species' status conducted to ensure that the listing classification of a species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants (List) (50 CFR 17.11 - 17.12) is accurate. The 5- year review is required by section 4(c)(2) ofthe Endangered Species Act of 1973, as amended (ESA) and was prepared pursuant to the joint National Marine Fisheries Service (NMFS) and U.S. Fish and Wildlife 5 year Review Guidance and template (USFWS and NMFS 2006). The NMFS Office of Protected Resources led the 5-year review. We relied on peer-reviewed publications, and government and technical reports. We gathered information through September 2017"--Page 1.

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 Terra written by Michael Novacek and published by Farrar, Straus and Giroux. This book was released on 2008-11-11 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: A paleontologist awakens us to the "extinction event" that human activity is bringing about today The natural world as humans have always known it evolved close to 100 million years ago, with the appearance of flowering plants and pollinating insects during the age of the dinosaurs. Its tremendous history is now in danger of profound, catastrophic disruption. In Terra, a brilliant synthesis of evolutionary biology, paleontology, and modern environmental science, Michael Novacek shows how all three can help us understand and prevent what he (and others) call today's "mass extinction event." Humanity's use of land, our consumption, the pollution we create, and our contributions to global warming are causing this crisis. True, the fossil record of hundreds of millions of years reveals that wild and bounteous nature has always evolved not quietly but thunderously, as species arise, flourish, die off, and are replaced by new species. We learn from paleontology and archaeology that for 50,000 years, human hunting, mining, and agriculture have changed many localities, sometimes irrevocably. But today, Novacek insists, our behavior endangers the entire global ecosystem. And if we disregard—through ignorance, antipathy, or apathy—the theory of evolution that developed with our modern understanding of the Earth's past, we not only impede enlightenment but threaten any practical strategy for our own survival. The evolutionary future of the entire living planet depends on our understanding this.

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 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.
