Section 1: Ecology

Fundamental concepts: Abiotic and biotic components

scales (population, species, community, ecosystems, biomes)

niches and habitats.

Population ecology: Population growth rates (density dependent/independent)

metapopulation ecology (colonization, persistence, extinction, patches, sources, sinks)

age-structured populations.

Interactions: Types (mutualism, symbiosis, commensalism, competition, parasitism, predation, etc)

ecophysiology (physiological adaptations to abiotic environment)

prey-predator interactions (Lotka-Voltera equation etc)

Community ecology: Community assembly, organization and succession

species richness, evenness and diversity indices, species-area relationships

theory of island biogeography Ecosystems structure and function: trophic levels and their interactions

nutrient cycles

primary and secondary productivity

Section 3: Mathematics and Quantitative Ecology

Mathematics and statistics in ecology: Simple functions (linear, quadratic, exponential, logarithmic, etc)

concept of derivatives and slope of a function

permutations and combinations

basic probability (probability of random events

sequences of events, etc)

frequency distributions and their descriptive statistics (mean, variance, coefficient of variation, correlation, etc).

Statistical hypothesis testing: Concept of p-value

Type I and Type II error, test statistics like t-test and Chi-square test

basics of linear regression and ANOVA.
