Loss of Biodiversity
threats of biodiversity
Extinction (natural causes),
H - habitat destruction I - invasive species P - pollution (pesticides, DDT) P- population (human pop. growth) O - over harvesting(poaching)
What does HIPPO stand for
Flagship species
attracted to the public Ex: giant panda
indicator species
conditions Ex: brook trout (when you see a brook trout you know the conditions of the water are clean/safe)
species evenness
distribution of each species in the community
benefits of biodiversity
food, drugs, medicines, a healthy ecosystem, healthy biosphere and ecotourism
killed
if an animal is endangered, threatened, or vulnerable it cannot be _____________
Umbrella species
large areas Ex: tiger

the endangered species act tells us that you are not allowed to ...
endangered
those considered in imminent danger of extinction
threatened
those likely to become endangered, at least locally, in the near future
vulnerable
those that are naturally rare or have been locally depleted to a level that puts them at risk; future listing
genetic diversity
total number of genetic characteristics of a species
Species richness
total number of species
Species diversity
variety of different living things
ecological (habitat) diversity
variety of environments produced from the interaction between the biotic and abiotic factors
biodiversity
variety of species in an ecosystem (3 levels of biodiversity)
Kudzu vine, brown tree snake, can toad.. these have no predators so they over populate
what are some invasive species
diversity is high
what is it when there is a great mix in species
humans
what is the main cause of extinction in different species?
