    Study Notes

    Community Ecology

    • The primary focus of community ecology is the interactions between different species in a community.

    Biodiversity

    • The main factor affecting the uneven distribution of biodiversity is the variation in environmental conditions such as temperature, rainfall, and latitude.

    Ecosystems

    • Coral reefs are considered the most productive and complex ecosystems on Earth.

    Extinction

    • Habitat destruction is the primary cause of extinction.

    Interactions

    • Mutualism is a type of interaction where both species benefit.

    Symbiotic Relationships

    • Mycorrhizal fungi live with plant roots and form a mutualistic relationship.

    Autotrophic Organisms

    • Autotrophic organisms are also known as producers.

    Energy Transfer

    • Only 10% of energy passes to the next trophic level.

    Ecological Succession

    • The term for the colonization of habitats devoid of life is primary succession.

    Community Structure

    • The term for the most abundant species in a community is dominant species.
    • Keystone species have a large impact on the community structure by determining the food web of an ecosystem.

    Biodiversity Hotspots

    • Biodiversity hotspots are areas with high levels of endemism and species richness.

    Genetic Variability

    • Low genetic variability leads to reduced fitness and increased extinction risk.
    • A small population can become stuck in an evolutionary dead end due to low genetic variability.
