Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. Species richness (SR) per lake ranged from seven to 26 (mean = 13.22, SD = 4.48) and functional dispersion (FDis) ranged from 0.09 to 0.23 (mean = 0.16, SD = 0.04). The PowerPoint PPT presentation: "Species Diversity" is the property of its rightful owner. • Species diversity is all the differences within and between populations Ecological Communities species diversity and community structure. Species Abundance = Relative abundance of species b. diversity available to humans in plant species, so that the genetic diversity can be safely conserved and efﬁciently used. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.

However, empirical estimates of Hill numbers, including species richness, tend to be an increasing function of sampling effort and, thus, tend to increase with sample completeness. At the outset, let us be clear why the prob-lem of understanding species diversity is com-plicated. Species diversity is defined as the number of species and amplitude of each species that live in a particular location or ecological community. At the outset, let us be clear why the prob-lem of understanding species diversity is com-plicated. 13.2.1 Species Richness This is the oldest and the simplest concept of species diversity - the number of species in the community or the region.
