Chapter 6: Wild Species and Biodiversity
Biological Wealth
Makes up our ecosystem capital and provides intrumental value
Instrumental value is value for humans
Intrinsic value is value for own sake
Biodiversity is dimensional
Genetic diversity
Species diversity
Ecosystem diversity
Range of communities and ecosystems
Biodiversity
Declining- North America and global extinction on the rise
Tropics covers about 40% of the earth's area
Tropics are highly diversed
Species decline is due to "HIPPO"
H- habitat destruction
I- invasive species
P- pollution
O- over exploitation
P- population (human)
Biodiversity
Conversion
Habitat Destruction is the greatest source of loss of biodiversity
Fragmentation
Simplification
Intrusion of other species
Invasive species are organisms that are not native to an area and can cause environmental change
Resons for invasion include deliberate, gradual, and accidental
Invasive species include:
Spotted lantern fly
Emerald Ash Borer
Autumn Olive
Spotted Knapweed
Biodiversity Pollution
Biological- pathogens and parasites
Chemical- nutrients, EDCs, industrial waste
Physical- light, sediment, noise, and thermal
Consequences of Biodiversity
Loss of ecosystem services
Keystone species
Ecotourism
K vs. R strategists
Conservation
Lacey Act
Endangered species act- listing, critical habitat, recovery plans
Endangered species legislation
