Book Synopsis Wading Birds as Biological Indicators by : Thomas W. Custer
Download or read book Wading Birds as Biological Indicators written by Thomas W. Custer and published by . This book was released on 1977 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1975 we studied the suitability of wading birds (herons and their allies) as biological indicators in the coastal environment. Eight teams of investigators located and censused 198 colonies along the Atlantic coast from Maine to Florida. Fourteen species including over one-quarter million breeding birds were censused. Wading bird colony sites are generally active each year and the number of colonies may have recently increased in some areas of the coast. The breeding population of wading birds was correlated with the area of coastal wetlands by State. The use of wading birds to their full potential as biological indicators requires further exploration: survey and reproductive success methods need to be tested, the survey of colonies repeated, available historical information assembled, and habitat requirements measured.

Book Synopsis Conservation Monitoring in Freshwater Habitats by : Clive Hurford
Download or read book Conservation Monitoring in Freshwater Habitats written by Clive Hurford and published by Springer Science & Business Media. This book was released on 2009-12-09 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: As in the terrestrial environment, most data collection from freshwater habitats to date falls into the survey, surveillance or research categories. The critical difference between these exercises and a monitoring project is that a monitoring project will clearly identify when we need to make a management response. A Model for Conservation Management and Monitoring Monitoring (as defined by Hellawell) is essentially a tool of practical conservation management, and Fig. 1.1 shows a simple, but effective, model for nature conser- tion management and monitoring. The need for clear decision-making is implicit in this model. First we must decide what would represent a favourable state for the key habitat or species, and then we must decide when to intervene if the state is (or becomes) unfavourable. A third, often overlooked, but equally important, decision concerns when we would consider the habitat or species to have recovered; this is unlikely to be the same point that we became concerned about it. This decision not only has resource imp- cations, it can also have major implications for other habitats and species (prey species are an obvious example). All of these decisions are essential to the devel- ment of an efficient and effective monitoring project.

Book Synopsis Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments by : Elżbieta Kalisińska
Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Download or read book Everglades written by Steve Davis and published by CRC Press. This book was released on 1994-01-01 with total page 954 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 31 chapters provide a wealth of previously unpublished information, plus topic syntheses, for a wide range of ecological parameters. These include the physical driving forces that created and continue to shape the Everglades and patterns and processes of its flora and fauna. The book summarizes recent studies of the region's vegetation, alligators, wading birds, and endangered species such as the snail kite and Florida panther. This referee-reviewed volume is the product of collaboration among 58 international authors from 27 institutional affiliations over nearly five years. The book concludes with a synthesis of system-wide restoration hypotheses, as they apply to the Everglades, that represent the integration and a collective viewpoint from the preceding 30 chapters. Techniques and systems learned here can be applied to ecosystems around the world.
