Anne Magurran is a professor at the University of St. Andrews, Scotland and an ecologist interested in the measurement, conservation and evolution of biological diversity.
Brian McGill is a professor at the University of Arizona. He is interested in understanding and measuring how human-caused global change especially global warming and land cover change affect communities of organisms. He works with large datasets from many different types of organisms and locations. The strength of the volume is Parts III and IV on, respectively, species abundance distributions and aspects of diversity other than abundance.
The former, in particular, contains a set of closely connected chapters that walk through the various concepts and metrics with clear guidelines on which of the very many metrics are the most useful. Scheiner, Arlington, Virginia. Convert currency. Add to Basket. Compare all 27 new copies.

Biological Diversity provides an up to date, authoritative review of the methods of measuring and assessing biological diversity, together with their application. However the rapid development of new methods, theinconsistent and sometimes confusing application of old ones, and the lack of consensus in the literature about the best approach, means that there is a real need for a current synthesis. The final section of the book turnsto a selection of contemporary challenges such as measuring microbial diversity, evaluating the impact of disturbance, assessing biodiversity in managed landscapes, measuring diversity in the imperfect fossil record, and using species density estimates in management and conservation.

Some forms of management may involve making land-use decisions through such mechanisms as environmental markets Pindilli and Casey , which are often incorporated in regulatory frameworks that guide management of species and habitats Salzman and Ruhl A related issue that merits discussion is whether expansion of the current index to include taxa other than vascular plants would improve its suitability for measuring biological diversity. In total, individuals, species, 88 genera and 45 families were recorded from Kilombero grasslands. In another empirical study, Axmacher et al. With adequate training and supervision, non-professional volunteers can be as proficient as professionals in many tasks, as shown by a number of quantitative evaluations of volunteer-collected data [e. But we believe there are serious and unaddressed concerns about the suitability of ecological integrity assessment as described by Faber-Langendoen et al. Finally, even under ideal circumstances, the metric would be at best an ambiguous measure of native plant diversity: a large mean C at a site can be obtained when just one or a few high-value species are observed, and a much smaller mean C can be obtained from the range of conservatism values resulting when numerous species are observed.
