Ecosystem Services
The four types of ecosystem services
provisional, regulating, supporting, cultural
Example: excess hunting decreases the genetic diversity of a population, decreasing it's overall size
Population Bottleneck
a group of populations together
Areas with high levels of biodiversity
between 0-30 degrees latitude
Example: a park built by a forest
cultural
Example: Koalas
Specialist Species
Species
a population of organism that can breed together and produce fertile offspring
Biomes with the highest biodiversity
tropical rainforests and coral reefs
Species Diversity
the range/amount of species within an ecosystem
Example: the food web or the nitrogen cycle
supporting
Example: Deer
Generalist Species
Population
a number of organism in a time and place
List One Legislation to Protect Ecosystems
- Endangered Species Act (ESA)
- Convention on International Trade of Endangered Species (CITES)
Ecosystem Diversity
the variety of ecosystems in a geographical location
Example: trees provide us with oxygen to breathe in
provisional
Example: Otters
Indicator Speices - reflects the health of the environment as they're sensitive to changes
Ecosystem
an area consisting of biotic and abiotic factors
The Shannon Index Measures
diversity in regards to both species richness and evenness
Species Evenness
disteribution of a species
Example: CO2 sequestration
Regulating
Example: Bees
Keystone Species - the ecosystem is heavily dependent on these species
Abiotic vs. Biotic
nonliving vs. living
The Biggest Threats To Biodiversity Are (HINT: HIPPCO)
H - habitat destruction
I - invasive species
P - pollution
P - poaching
C - climate change
O - over exploitation
Species Richness
number of species
