   How do biologists measure species diversity?

   • Biologists have developed three quantitative measures of species diversity as a means of measuring and comparing species diversity: Alpha diversity (or species richness), the most commonly referenced measure of species diversity, refers to the total number of species found in a particular biological community, such as a lake or a forest.

   What are diversity measures?

   • Various diversity measures have been developed and tailored to specific applications in different fields including ecology, biology, and economics. Mathematically, one can describe populations in terms of species numbers ni (number of entities of type i) or clone counts ck (number of species of size k ).

   How do we estimate species diversity in different habitats?

   • There are many mathematical models that have been developed to quantify species diversity in different habitats. While these models differ in the exact method of diversity estimation, they all include two important components: species richness and species evenness.

   What is a unified method for measuring diversity?

   • A unified method for measuring diversity was developed by Hill (1973), and re-introduced to ecologists by Jost (2006). This method takes as its starting point that both the number and the relative abundance of species are components of diversity, and that these components cannot be fully separated.

   Why are ecologists attracted to species richness as a diversity metric?

   • Ecologists may be attracted to species richness as a diversity metric because true richness depends only on the number of species, but not on their relative abundances. However, estimates of richness are, in fact, highly sensitive to the relative abundances of species in the community being sampled.

   Can diversity be measured in a single measure?

   • Quantifying the diversity of a given population in terms of a single measure such as richness does not fully describe the underlying distribution of species or other properties. Various diversity measures have been developed and tailored to specific applications in different fields including ecology, biology, and economics.

   Mar 3, 2020 · In each of these disciplines, diversity is a measure of the range and distribution of certain features within a given population. It is considered a key attribute that can be dynamically varying, influenced by intra-population interactions, and modified by environmental factors.
