polymorphic gene locus

a locus that has more than one alleles in more than 1 percent of the populations

7

Simpson's index of biodiversity

a measure of the diversity of a habitat

8

species evenness

a measure of how evenly represented the species are

9

species richness

a measure of how many different species are present

10

climate change

significant long-lasting changes in weather patterns

11

monoculture

a crop consisting of one strain of one species

12

keystone species

a species that has a disproportionate effect on its environment relative to its abundance
