Book Description
Excerpt from Key to the Families of North American Insects: An Introduction to the Classification of Insects More than fifty thousand different species of insects are now known from North America. Their descriptions fill libraries and their final identification requires the knowledge of specialists. Obviously no single volume can provide for their determination. But this host of species is divided into groups of related forms, the families of insects, and it is with their recognition that the present work deals. Identification of the families has been effected by means of analytical keys, which have been arranged as dichotomies. In the first couplet, for example, two contrasting descriptions are given, one of which should agree with the insect to be determined. The number at the end of this description indicates the couplet which should then be studied, and so on until the final name is secured. All of the keys have been arranged in this way, as the writers' experience in the classroom shows that specimens can be most easily and rapidly classified with a key of this type, which also requires much less space for printing. While the dichotomies frequently represent the natural relationships or the lines of phyletic development, no attempt has been made to preserve natural divisions wherever the convenience and practical Opera tion of the keys would have been sacrificed.

Book Description
Rapid depletion and degradation of species in diverse ecosystems and the implications of this for human welfare have the cause for increasing concern. Biodiversity or variability among living organisms and the ecological complexes of which they are a part, is essential for ensuring the basic ecological services and resources necessary for sustaining human welfare. The loss of biodiversity is therefore, considered one of the most serious problem threatening the world today. An understanding of the ecological implications of the increasing loss of bodiversity, not to mention of the economic implications, has therefore, became vital. A biodiversity loss is irreversible. A calls for increased caution in our efforts to convert and exploit natural resources. Some minimal level of biodiversity is necessary to main ecological functioning, which in turn is necessary for generating the biological resources on which human welfare depends. Needless to emphasive that substantial biodiversity loss occurs due to forest clearing and degradation, leading to the need for assessing biodiversity in different ecosystems. Keeping these aspects in mind, the present volume highlights biodiversity in different cropping systems besides that the impact of cold and hot deserts. Selection of the topics in the various chapters is essentially because of the experience of the authors in the field of biodiversity.
