Available in PDF, EPUB and Kindle. Book excerpt: Investigators have long recognized the importance of certain elements, commonly called "minerals," in the diet of humans and animals and in the soil that supports plants, in that these elements are essential for the life or optimum health of the organisms. Deficiencies of 20 to 24 elements in animals and man and of 13 to 18 elements in plants have been recognized. At the same time, an understanding of the responses of these organisms to the insult of toxic concentrations of these and other elements also has been of interest. More recently, concern has arisen regarding the effects of an organism's exposure to the more subtle chronic and subchronic concentrations of certain elements that industrial and other human activities are releasing into the environment.

Download or read book Ecological Impacts of Non Native Invertebrates and Fungi on Terrestrial Ecosystems written by David Langor and published by Springer Science & Business Media. This book was released on 2009-01-21 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the arrival of Europeans about 500 years ago, an estimated 50,000 non-native species have been introduced to North America (including Hawaii). Non-native species figure prominently in our lives, often as ornamentals, sources of food or pests. Although many introduced species are beneficial, there is increasing awareness of the enormous economic costs associated with non-native pests. In contrast, the ecological impacts of non-native species have received much less public and scientific attention, despite the fact that invasion by exotic species ranks second to habitat destruction as a cause of species loss. In particular, there is little information about the ecological impacts of hyper-diverse groups such as terrestrial fungi and invertebrates. A science symposium, Ecological impacts of non-native invertebrates and fungi on terrestrial ecosystems, held in 2006, brought together scientists from the USA and Canada to review the state of knowledge in this field of work. Additional reviews were solicited following the symposium. The resulting set of review/synthesis papers and case studies represents a cross-section of work on ecological impacts of non-native terrestrial invertebrates and fungi. Although there is a strong focus on Canadian work, there is also significant presentation of work in the northern USA and Europe.
