Summary Introduction

To describe: The way in which diversity,stability, redundancy, keystone, and idiosyncratic hypotheses link species richness with ecosystem function.

Introduction: The species richness of any particular area is called as the biodiversity of that area. The biodiversity includes various species of both fauna and flora in a particular habitat. The species richness has a direct relationship with the productivity of the ecosystem.

SUBJECT : Biology - Ecology How would you describe the slope of a rank-abundance curve that vary with increasing species evenness?
Ecology and Biology: Shannon Diversity Index: Definition & Example The Shannon Diversity Index (sometimes called the Shannon-Wiener Index) is a way to measure the diversity of species in a community. Denoted as H, this index is calculated as: H = -Σpi * ln(pi) where: Σ: A Greek symbol that means “sum” ln: Natural log pi: The proportion of the entire community made up of species i The higher the value of H, the higher the diversity of species in a particular community. The lower the value of H, the lower the diversity. A value of H = 0 indicates a community that only has one species. The Shannon Equitability Index is a way to measure the evenness of species in a community. The term “evenness” simply refers to how similar the abundances of different species are in the community. Denoted as EH, this index is calculated as: EH = H / ln(S) where: H: The Shannon Diversity Index S: The total number of unique species What is the Shannon diversity index value for this community?

A realized niche describes the conditions of the environment in which a species is 
actually found, while a fundamental niche describes the potential environmental conditions
 tolerated by a species. True False
