Beschreibung:
A power law called the species-area relationship describes the finding that the number of species is proportional to the size of the area in which they are found, raised to an exponent (usually, a number between 0.2 and 0.3). In their Perspective, May and Stumpf discuss new results from a survey of five tropical forest census areas containing a total of a million trees. They explain how this large data set can be used to fine-tune the existing power law so that it provides a better prediction of species diversity in small census samples.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉May, R M -- Stumpf, M P -- New York, N.Y. -- Science. 2000 Dec 15;290(5499):2084-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zoology Department, Oxford University, Oxford OX1 3PS, UK. robert.may@zoo.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11187834" target="_blank"〉PubMed〈/a〉
