|
biodiversity
|
place where an organism lives
|
habitat
|
a group of organisms that can breed to produce fertile offspring
|
species
|
variations between organisms within the same species
|
genetic biodiversity
|
type of sampling - using arbitrary values to decide where to sample
|
random sampling
|
type of sampling - picking an area you know is good/easy to sample
|
opportunistic sampling
|
type of sampling - dividing habitat into areas that appear different + sampling each
|
stratified sampling
|
type of sampling - taking samples at fixed intervals across a habitat
|
systematic sampling
|
square frame with little mini squares inside that is used for sampling

a different version of a gene
|
allele
|

climate change
|
a crop consisting of one strain of one species
|
monoculture
|
mating organisms with desired traits in order to have offspring with desired traits
|
selective breeding
|
when every member of a species dies
|
extinction
|
an important species that has a disproportionately high effect on its ecosystem

active management to maintain biodiversity
|
conservation
|
protection of area and removal of human impact to maintain biodiversity
|
preservation
