Definition species richness
Webspecies richness is generally used as a measure of diversity within a single ecological community, habitat or micro-habitat, although the definition of small depends on the species in question. Ecologists have long been intrigued by the fact that small-scale species richness can vary substantially among WebEstimating species richness Nicholas J. Gotelli and Robert K. Colwell 4.1 Introduction Measuring species richness is an essential objec-tive for many community ecologists and conserva-tion biologists.

WebThe rarefaction curve is a plot of the number of species against the number of samples. This curve is created by randomly re-sampling the pool of N samples several times and then plotting the average number of species found on each sample. Generally, it initially grows rapidly (as the most common species are found) and then slightly flattens ... WebSpecies richness S is the simplest measure of biodiversity and is simply a count of the number of different species in a given area. This measure is strongly dependent on sampling size and effort ...

WebSpecies richness is the number of different species that occurs in a defined area. In practice, estimates of species richness (or any other metric of species diversity) are typically restricted to a particular taxonomic group (e.g., trees and mammals), or a particular trophic level (e.g., primary producers and herbivores). ...
