Species Evenness is a measurement of:

• the number of different species in a community

• how close in numbers each species is in a community or ecosystem.

• how spread out the species are in a community

• How rare the species are in a community

Sample 1 has 4 different species, with about 300 individuals of each. Sample 2 has 4 different species, with way more individuals of some species than others. Which community has higher Species Evenness?

• Sample 1

• Sample 2

• They are both equal

• I can't tell

A community has 10 lions, 80 zebras and 10 elephants. What is the relative abundance of each species?

• 3

• 100

• It's impossible to tell.

Site 1 has a Simpon's Diversity Index of 0.81 and site 2 has 0.43. Choose the correct statement.

• Site 1 is more biodiverse than site 2

• Site 2 is more biodiverse than site 1

• You cannot compare the biodiversity of two different sites

• These numbers are qualitative and therefore more data is required to compare both sites
