Question

How would you calculate a species' richness?

Answer 1

here is ur answer----------------❤❤❤

Species Richness

Species richness is a measure of the number of species found in a sample. Since the larger the sample,

the more species we would expect to find, the number of species is divided by the square root of the

number of individuals in the sample. This particular measure of species richness is known as D, the

Menhinick's index.

D = s

√N

where s equals the number of different species represented in your sample, and N equals the total

number of individual organisms in your sample.

Species Diversity

Species diversity differs from species richness in that it takes into account both the numbers of species

present and the dominance or evenness of species in relation to one another. As a measure of species

diversity, we will calculate the Shannon index, H. Interestingly Shannon, a physicist, developed the

index as a formula for measuring the entropy of matter in the universe. It turns out that the

mathematical relationships hold true whether one is dealing with molecules in solution or species in an

ecological community.

H = ∑ (pl

) |ln pl

|

Where (pl

) is the proportion of the total number of individuals in the population that are in species “l”.

Understanding the Difference Between Species Richness and Species Diversity

Consider the following data from samples of organisms obtained from two different biological

communities.

Hey buddy here is ur answer !!

》Species richness is ameasure of the number ofspecies found in a sample.

》Since the larger the sample, the more species we would expect to find, the number of bspecies is divided by the square root of the number of individuals in the sample.
