Descrizione

61 pages including index. Deals with the consequences of ecological change, particularly those brought about by human activity. "It commonly happens that man, while pursuing his own ends, incidentally uproots, fragments or destroys communities of plants and animals. Subsequent changes include the re-constitution of parts and wholes of those communities from surviving organisms and immigrants. Some of the immigrants become pests, also some of the native organisms." Attempts to point out the intellectual status of the subject as a whole and indicate a few of the avenues along which progress can be made, and to comment upon certain methods of study. Good unmarked copy with brown age spotting to both endpapers and some waviness to pages. Some bumping to corners. Dust jacket has light to moderate age spotting. Book
