Study Notes

Functional Biodiversity

Variety of biological processes, functions, and characteristics within a specific ecosystem.

Benefits of Biodiversity

Anthropocentric Benefits:
- Provides scientific information, useful materials, and recreational, medical, or consumptive benefits for humans.
Anthropocentric Nature:
- Choosing to protect species or ecosystems due to potential future benefits.

Ecocentric Benefits of Biodiversity

Ecosystem Services:
- Purifying water and air.
- Pollinating crops.
- Stabilizing soil.
- Maintaining heat balance in the atmosphere.
- Cycling critical nutrients.
Economic Context:
- Mangrove forests mitigate damage from typhoons, acting as a protective barrier against strong winds and waves.
Intrinsic Value:
- The mere existence of healthy and vibrant ecosystems (like coral reefs or tropical forests) holds inherent value, even if they are not directly experienced by humans.

Importance of Biodiversity

Not explicitly stated in the text, but biodiversity underpins ecosystem stability, resilience, and overall health.

Measuring and Monitoring Biodiversity

Ideal measurement involves direct assessment of processes (productivity rates, pollination rates, species interactions). However, this is very time consuming.
Surrogate Species Method:
- Uses a select group of species to represent broader sets of species and habitats.
- This simplifies and speeds up the monitoring process.
Surrogates Species Approaches:
- Keystone Species: Essential community roles, influence far beyond their abundance.
- Umbrella Species: Require large habitats, protecting them indirectly protects other species.
- Indicator Species: Their presence or absence signals the health of a whole habitat.
- Flagship Species: Charismatic species used to raise public awareness and support for biodiversity conservation efforts.

Keystone Species

Critical to maintaining ecosystem stability, removing them can cause significant changes.

Umbrella Species

Extensive home range offers indirect protection to other species in their habitat.

Species Diversity:

Reflects the variety and relative abundance of different species within a specific area, including their interactions and distribution.

Ecological Diversity:

Ecosystem Diversity:
- Abundance and distribution of habitats, biotic communities, and ecological processes within a specific area.

Aspects of Species Diversity:

Species Richness (S):
- Total number of species present.
Species Evenness (E):
- Relative abundance or proportion of each species.

Biodiversity Attributes and Ecosystem Processes:

Compositional Biodiversity:
- Describes the types of components and their abundance within a defined area.
Structural Biodiversity:
- Represents the arrangement of components over space and time.
