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

keystone species

major effect Ex: bison

species dominance

most abundant species

Take, sell, import/export, possess, or transport endangered animals

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?
