General Ecology - The historical development of ecology. Ecology of the interactions between organisms and the physical environment: Conditions; Spatial and temporal variations; Adaptations in response to variations in environmental conditions; Limiting factors; Tolerance ranges; Environmental optima; Biological rhythms - climatic factors; Classification of climates; Phytogeographic zonation; Hints of paleoclimatology; Biomes. Evolutionary Ecology - Genetic analysis of populations; Hardy-Weinberg's law; Genetic variability; Evolutionary forces (mutation, selection, gene flow, genetic drift); inbreeding; Wahlund effect; Balanced polymorphisms; Linkage disequilibrium; supergenes; Genetic divergence; Species concept; Reproductive isolation mechanisms; Speciation mechanisms; Hybrid zones and reinforcement; Sibling species; Biodiversity at the genetic level. Population ecology - Demography and dynamics: population structure and growth; Demographic parameters; Demographic tables; Intrinsic growth rate - numerical regulation of populations; Density dependent and independent factors; Exponential growth; environmental carrying capacity - logistic growth curve. Interspecific interactions: symbiosis; commensalism; inquilinism; antibiosis; parasitism; adaptations to parasitic life; coevolution; predation - adaptations to predation; cryptism; mimicry; intraspecific competition; interspecific competition; ecological niche; Principle of competitive exclusion; character displacement; r and K selection. Community and Ecosystem Ecology – What is community and its diversity, diversity indices, natural successions. Principles of Biogeography and islands biogeography. Ecosystems: structure, primary and secondary productivity, flux of energy through the ecosystem, trophic webs.
