Understanding Biodiversity and Ecosystem Services

Biodiversity

Variety of life forms in ecosystems.

Generalist Species

Broad niche, diverse diet, adaptable habitats.

Specialist Species

Narrow niche, limited diet, specific habitats.

Ecological Niche

Pattern of living for a species.

Keystone Species

Crucial species affecting ecosystem structure.

Population Control Factors

Elements limiting population size and growth.

Density-independent Factors

Limit population size regardless of density.

Density-dependent Factors

Effects vary with population density.

Ecosystem Diversity

Variety of habitats in an area.

Species Diversity

Number and balance of species in ecosystems.

Genetic Diversity

Variation of genes within a population.

Species Richness

Total number of different species present.

Species Evenness

Balance of individual organisms among species.

Biodiversity Benefits

Higher biodiversity enhances ecosystem health.

Genetic Diversity Benefits

Improves population resilience to environmental stress.

Bottleneck Event

Population reduction affecting genetic diversity.

Inbreeding Depression

Reduced fitness from mating closely related individuals.

Ecosystem Resilience

Ecosystem's ability to recover after disturbances.

Ecosystem Services

Natural benefits provided to humans by ecosystems.

Provisioning Services

Direct goods/products from ecosystems for human use.

Regulating Services

Ecosystem processes that moderate natural conditions.

Supporting Services

Ecosystem processes that facilitate human activities.

Cultural Services

Revenue from recreational and scientific ecosystem benefits.

Anthropogenic Activities

Human actions disrupting ecosystem functions.

Overfishing

Depleting fish populations affecting economic stability.

Deforestation

Clearing forests impacting climate and biodiversity.

Pollinator Habitat Loss

Decline in habitats affecting pollination services.

Wetland Functions

Natural filtration and groundwater purification processes.
