Book Description
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 Description
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.

Book Description
« This report is a compilation and analysis of the results of nearly 10 years of testing the lethal dietary toxicities of pesticidal and industrial chemicals to young bobwhites (Colinus virginianus), Japanese quail (Coturnix c. japonica), ring-necked pheasants (Phasianus colchicus), and mallards (Anas platyrhynchos). A total of 131 compounds were tested. » --

Book Description
The 31 chapters provide a wealth of previously unpublished information, plus topic syntheses, for a wide range of ecological parameters.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.
