calculating biodiversity

Question 1

what’s species richness

Answer 1

number of different species

Question 2

what does the n, N stand for in Simpsons index of decay

Answer 2

N= total number of organisms of all species
n= total number of a particular species

Question 3

what’s genetic diversity

Answer 3

-measure of how many variations there are in the genetic code or between individuals of a particular species/ between different species

Question 4

how to calculate genetic diversity

Answer 4

-calculating percentage of gene loci in the population that have more than 1 allele
-some loci have more than 2 alleles (polymorphic)= number of polymorphic gene loci/total number of loci

Question 5

what is simpsons index of decay

Answer 5

1- (E(n/N)^2)

Question 6

what does a low Simpsons index mean

Answer 6

-the habitat is dominated by one/few species
-ecosystem is unstable and less likely to cope with change
