Book Description
El Niño is a meteorologic/oceanographic phenomenon that occurs sporadically (every few years) at low latitudes. It is felt particularly strongly in the eastern Pacific region, notably from the equator southwards along the coasts of Ecuador and Peru. The El Niño is a component of the ENSO (El Niño Southern Oscillation) which accentuates the intimate and causal connection between atmospheric and marine processes. Obvious manifestations of El Niño in the eastern Pacific are anomalous warming of the sea; reduced upwelling; a marked decline in fisheries, and high rainfall with frequent flooding. The 1982/83 El Niño was exceptionally severe, and was probably the strongest warming of the equatorial Pacific Ocean to occur during this century. The warming was intense and spread over large parts of the Pacific Ocean and penetrated to greater depths than usual. Many eastern Pacific coral reefs that had exhibited uninterrupted growth for several hundred years until 1983 were devasted by the disturbance and are now in an erosional mode. Marine species were adversely affected. The consequent depletion of the plant food base resulted in significant reductions in stocks of fish, squid etc. This led to a mass migration and near-total reproductive failure of marine birds at Christmas Island. Emphasis in this volume is placed on disturbances to benthic communities; littoral populations; terrestrial communities and extratropical regions.

Encyclopedia of Modern Coral Reefs

Encyclopedia of Modern Coral Reefs PDF Author: David Hopley
Publisher: Springer Science & Business Media
ISBN: 904812638X
Category : Science
Languages : en
Pages : 1226

Book Description
Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

Pinnipeds and El Niño

Pinnipeds and El Niño PDF Author: Fritz Trillmich
Publisher: Springer Science & Business Media
ISBN: 3642763987
Category : Science
Languages : en
Pages : 299

Book Description
El Niño is a meteorological and oceanographic phenomenon, which occurs at irregular intervals in the eastern tropical Pacific. Its most obvious characteristic is the warming of surface waters, which causes enormous disturbances of the marine environment. A severe Niño may also affect continental systems worldwide. This book gathers in a comprehensive way the information available on the effects of the exceptionally strong 1982-83 Niño on a group of marine mammals, the pinnipeds. It presents an analysis of the effects of environmental stress on the populations of top predators. Data and interpretations are based on a most unusual collection of long-term studies of pinniped population dynamics, behavior and ecology which spanned the El Niño event. The responses of pinniped populations to the El Niño disturbance of the marine ecosystem also has important implications for the management and conservation of marine mammal populations.

Marine Ecosystems and Climate Variation

Marine Ecosystems and Climate Variation PDF Author: Nils Chr. Stenseth
Publisher: OUP Oxford
ISBN: 019152316X
Category : Science
Languages : en
Pages : 266

Book Description
This research level text focuses on the influence of climate variability on the marine ecosystems of the North Atlantic. The ecological impact of climate variability on population dynamics is addressed at the full range of trophic levels, from phytoplankton through zooplankton and fish to marine birds. Climate effects on biodiversity and community structure are also examined. 40 scientists from around the world synthesise what is currently known about how climate affects the ecological systems of the North Atlantic and then place these insights within a broader ecological perspective. Many of the general features of the North Atlantic region are also seen in other marine ecosystems as well as terrestrial and freshwater systems. The final section of the book makes these generalities more explicit, so as to stimulate communication and promote co-operation amongst researchers who may previously have worked in semi-isolation. The book comprises 5 main sections: background (general introduction, atmospheric and ocean climate of the North Atlantic, and modelling methodology), plankton populations (phytoplankton and zooplankton), fish and seabird populations, community ecology (phytoplankton, benthos and fish), and the final section consisting of six commentaries from scientists working in areas outside the North Atlantic marine sector. In order to enhance integration, a series of introductions link chapters and sections. Throughout the book, numerous examples highlight different aspects of ecology-climate interactions. They document recent progress and illustrate the challenges of trying to understand ecological processes and patterns in the light of climate variations.

Climate Variability and the Global Harvest

Climate Variability and the Global Harvest PDF Author: Cynthia Rosenzweig
Publisher: Oxford University Press
ISBN: 9780198031475
Category : Science
Languages : en
Pages : 280

Book Description
The Earth's climate is constantly changing. Some of the changes are progressive, while others fluctuate at various time scales. The El Ni?o-la Ni?a cycle is one such fluctuation that recurs every few years and has far-reaching impacts. It generally appears at least once per decade, but this may vary with our changing climate. The exact frequency, sequence, duration and intensity of El Ni?o's manifestations, as well as its effects and geographic distributions, are highly variable. The El Ni?o-la Ni?a cycle is particularly challenging to study due to its many interlinked phenomena that occur in various locations around the globe. These worldwide teleconnections are precisely what makes studying El Ni?o-la Ni?a so important. Cynthia Rosenzweig and Daniel Hillel describe the current efforts to develop and apply a global-to-regional approach to climate-risk management. They explain how atmospheric and social scientists are cooperating with agricultural practitioners in various regions around the world to determine how farmers may benefit most from new climate predictions. Specifically, the emerging ability to predict the El Ni?o-Southern Oscillation (ENSO) cycle offers the potential to transform agricultural planning worldwide. Biophysical scientists are only now beginning to recognize the large-scale, globally distributed impacts of ENSO on the probabilities of seasonal precipitation and temperature regimes. Meanwhile, social scientists have been researching how to disseminate forecasts more effectively within rural communities. Consequently, as the quality of climatic predictions have improved, the dissemination and presentation of forecasts have become more effective as well. This book explores the growing understanding of the interconnectedness of climate predictions and productive agriculture for sustainable development, as well as methods and models used to study this relationship.

Geological Approaches to Coral Reef Ecology

Geological Approaches to Coral Reef Ecology PDF Author: Richard B. Aronson
Publisher: Springer Science & Business Media
ISBN: 0387335374
Category : Science
Languages : en
Pages : 457

Book Description
This book provides a unique perspective on the destruction - both natural and human-caused - of coral reef ecosystems. Reconstructing the ecological history of coral reefs, the authors evaluate whether recent dramatic changes are novel events or part of a long-term trend or cycle. The text combines principles of geophysics, paleontology, and marine sciences with real-time observation, examining the interacting causes of change: hurricane damage, predators, disease, rising sea-level, nutrient loading, global warming and ocean acidification. Predictions about the future of coral reefs inspire strategies for restoration and management of ecosystems. Useful for students and professionals in ecology and marine biology, including environmental managers.
