Section 1: Ecology
Population ecology; metapopulation dynamics; growth rates; density independent growth; density dependent growth; niche concept.
Species interactions: Plant-animal interactions; mutualism, commensalism, competition and predation; trophic interactions; functional ecology; ecophysiology; behavioural ecology.
Community ecology: Community assembly, organization and evolution; biodiversity: species richness, evenness and diversity indices; endemism; species-area relationships.
Ecosystem structure, function and services; nutrient cycles; biomes; habitat ecology; primary and secondary productivity; invasive species; global and climate change; applied ecology.
Section 2: Evolution
Origin, evolution and diversification of life; natural selection; levels of selection
Types of selection (stabilizing, directional etc.); sexual selection; genetic drift; gene flow; adaptation; convergence; species concepts.
Life history strategies; adaptive radiation; biogeography and evolutionary ecology.
