Tổng quan này nhằm mục đích để điều tra một số liên kết giữa lý thuyết và thực hành bảo tồn sinh thái và sau đó để đánh giá liệu các mối liên kết đã được hữu ích. Ngay từ đầu, chúng ta được rõ ràng, quản lý có thể thành công trong trường hợp không hoàn thành của một liên kết với lý thuyết. Chỉ cần suy nghĩ về những người nông dân và fanciers người nhanh chóng được nhân giống và di truyền cố định ngoạn mục giống thuần mà không có có kiến thức về chọn lọc tự nhiên.

From the outset let us be clear management can be successful in the complete absence of a link with theory. Just think about the farmers and fanciers who quickly bred and genetically fixed the many spectacular domesticated varieties without any knowledge of natural selection. In this case there was a link but it was in the opposite direction Darwin developed his theory of natural selection in part from the practice of selection by the stockbreeders. So given that theory can evolve from practice is the reverse possible can practice evolve from theory Put another way do we have the equivalent of a reference library of useful theory to help in management or is it better to rely on the experience of a manager Aquestion asked Maynard-Smith 1978 but not yet answered. Suppose for example that we are modeling energy flow through an ecosystem we may need the metabolic rate of a large number of species a laborious and expensive task. Fortunately because the theory is well established in this case all it is necessary to know is the weight of the individual animals concerned and whether they are single-celled or warm-blooded or not as the case may be. The equations of Kleiber s Law will then provide us the precise information we need. A similar approach is possible in plants Reich et al. 2006 . How often can we parallel such downloading in .
