intro to sustainability and conservation

three key threats to vaquita

are bycatch, habitat loss, and pollution.

what does increase population mean for bidoiversity

increase population threatens the biodiversity causing loss to biodiversity- demand for resources goes up so does the consumption

red index list is

shows the trends in overall extinction risk for species

according to red index list what is the most threatened species and what species is most rapidly moving to extinction

• amphibians

• corals

vaquita biggest threats

entanglement and drowning in gillnets

current rate of species extinctions

is estimated to be 100 to 1,000 times higher than the natural rate occured through earths history

planetary boundaries concept

the environmental limits of human activities which can occur without causing irreversible or catastrophic damage

4 planetary boundaries that have been over stepped

• climate change

• Biosphere integrity

• Biogeochemical flows

• Land-system change

5 key principles of conservation biology

• The diversity of species and ecosystems should be preserved.

• The untimely extinction of populations and species should be prevented

• Ecological complexity should be maintained

• evolution should continue

3 levels of biodiversity

• genetic diversity

• species diversity in an ecosystem

• ecosystem diversity all processes

species?

a morphologically distinct interbreeding group to produce offspring

Biological Community

The species that occupy a particular locality and the interactions among those species

limiting resources

limiting resources will limit the growth, survival or reproduction of a species population.

carrying capacity

maximum population an environment can support determined by the supply of resources

species richness

number of different species in a region

Functional diversity

The range of species and the traits / characteristics of these species that influence the functioning of ecosystems

3 pillars of sustainability

• environment

• social

• economics
