This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.

Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments

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.

With the underpinning role of forage legumes in the nitrogen economy and animal productivity from temperate grasslands certain to expand in the future, particularly in regions where their potential has not yet been realized, it is essential that the wealth of information currently available is widely disseminated. This book serves the purpose with

Grasses and Grassland Ecology provides an ecologically orientated introduction to this influential group of plants, summarizing the most recent scientific research in ecology and agriculture in the context of the older, classic literature. Ten chapters cover the morphology, anatomy, physiology and systematics of grasses, their population, community and ecosystem ecology, their global distribution, and the effects of disturbanceand grassland management.
