The Importance of Species
Author: Peter KareivaPublisher: Princeton University Press
ISBN: 1400866774
Category : Science
Languages : en
Pages : 446
Book Description
A great many species are threatened by the expanding human population. Though the public generally favors environmental protection, conservation does not come without sacrifice and cost. Many decision makers wonder if every species is worth the trouble. Of what consequence would the extinction of, say, spotted owls or snail darters be? Are some species expendable? Given the reality of limited money for conservation efforts, there is a compelling need for scientists to help conservation practitioners set priorities and identify species most in need of urgent attention. Ecology should be capable of providing guidance that goes beyond the obvious impulse to protect economically valuable species (salmon) or aesthetically appealing ones (snow leopards). Although some recent books have considered the ecosystem services provided by biodiversity as an aggregate property, this is the first to focus on the value of particular species. It provides the scientific approaches and analyses available for asking what we can expect from losing (or gaining) species. The contributors are outstanding ecologists, theoreticians, and evolutionary biologists who gathered for a symposium honoring Robert T. Paine, the community ecologist who experimentally demonstrated that a single predator species can act as a keystone species whose removal dramatically alters entire ecosystem communities. They build on Paine's work here by exploring whether we can identify species that play key roles in ecosystems before they are lost forever. These are some of our finest ecologists asking some of our hardest questions. They are, in addition to the editors, S.E.B. Abella, G. C. Chang, D. Doak, A. L. Downing, W. T. Edmondson, A. S.

NOAA Coastal Ocean Program Decision Analysis Series
Author: Seagrasses: Biology, Ecology and Conservation

Languages : en
Pages : 724
Book Description
Seagrasses are unique plants; the only group of flowering plants to recolonise the sea. They occur on every continental margin, except Antarctica, and form ecosystems which have important roles in fisheries, fish nursery grounds, prawn fisheries, habitat diversity and sediment stabilisation. Over the last two decades there has been an explosion of research and information on all aspects of seagrass biology. However the compilation of all this work into one book has not been attempted previously. In this book experts in 26 areas of seagrass biology present their work in chapters which are state-of–the-art and designed to be useful to students and researchers alike. The book not only focuses on what has been discovered but what exciting areas are left to discover. The book is divided into sections on taxonomy, anatomy, reproduction, ecology, physiology, fisheries, management, conservation and landscape ecology. It is destined to become the chosen text on seagrasses for any marine biology course.

Mitigating Potential Impacts of Ferry Terminal Siting and Design on Eelgrass Habitat

ISBN:
Category : Docks
Languages : en
Pages : 116
Book Description
"Increases in population and ferry traffic in western Washington require expansion of existing terminals, threatening the ecological functions of existing eelgrass ("Zostera marina" L.) meadows. Eelgrass meadows are affected by light reduction and other initial and long-term disturbances associated with terminal construction and maintenance, propeller wash, and bioturbation by macroinvertebrates. Technological mitigation measures showed that concrete blocks with clear plastic centers, reflective material placed under terminals, and artificial lighting can all enhance light under the terminals. Restoration of damaged meadows adjacent to terminals is proposed as an alternative"--National Sea Grant Library publication website.
Managing Seagrasses for Resilience to Climate Change
Author: Mats BjörkPublisher: IUCN
ISBN: 2831710898
Category : Climatic changes
Languages : en
Pages : 60
Book Description
Seagrasses are flowering plants that thrive in shallow oceanic and estuarine waters around the world. Although there are only about 60 species of seagrasses worldwide, these plants play an important role in many shallow, near-shore, marine ecosystems. There is growing evidence that seagrasses are declining globally because of anthropogenic impacts. This paper presents an overview of seagrasses, the impacts of climate change, and other threats to seagrass habitats. Finally, it proposes tools and strategies for managers to help support seagrass resilience.
