With Complete Solutions
species area relationship
species richness increases with area sampled
species and extinction
1. immigration of new species to a near island causes lower rate
of species present
2. immigration of new species to a distant island causes lowest
rate of species present
3. extinction on a small island means higher rate of species
present
4. extinction on a large island means less high rate of species
present
large islands...
have more species than small islands.
hot spots
large regions containing exceptional concentrations of endemic
plants and experiencing high rates of habitat loss.
hot spot qualifications
must contain 1500 endemic species of vascular plants
have a loss of >70% of its original native habitat
amount of carbon fixed depends on
climate and leaf area index
, primary productivity measures...
harvest biomass, chlorophyll concentration
NPP constrained by...
precipitation, temperature, nutrients, herbivory
secondary production is generated through the consumption of
organic matter by...
heterotrophs
Key transformation processes
decomposition, mineralization
Elizabeth colbert
first latitudinal gradient of biodiversity increases as you ski
down from Ellesmere Island.
Species-area relationship
species richness of a particular sample against the area of that
sample. species diversity increases with area sampled. large
islands have more species than small islands
habitat loss
major threat to biological diversity conservation.
Large and continuous habitat is reduced and divided into smaller
isolated patches of habitats.
Habitat fragmentation
