Those candidates who are going to appear in GATE 2020 examination are advised to check the complete syllabus of Ecology and Evolution. In this article, we are discussing the paper pattern and complete syllabus for Ecology & Evaluation subject.

GATE 2020 Syllabus for Ecology & Evaluation Syllabus

The syllabus of GATE exam is based on graduation level. The syllabus of every paper is quite different but Engineering Mathematics section is the same in most of the papers. This section will carry 15% of questions in the exam. Applicants are advised to check complete syllabus before starting the preparation of exam. 

GATE Syllabus for Ecology and Evaluation comprises of four sections. The following sections with their sub topics are given below:

  • Ecology
  • Evolution
  • Mathematics and Quantitative Ecology
  • Behavioural Ecology

Chapter 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.

Chapter 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;

Origin of genetic variation; Mendelian genetics; polygenic traits, linkage and recombination; epistasis, gene-environment interaction; heritability; population genetics; Molecular evolution; molecular clocks; systems of classification: cladistics and phenetics; molecular systematics; gene expression and evolution.

Chapter 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.

Chapter 4 – Behavioural Ecology

Classical ethology; neuroethology; evolutionary ethology; chemical, acoustic and visual signaling Mating systems; sexual dimorphism; mate choice; parenting behaviour Competition; aggression; foraging behaviour; predator–prey interactions; Sociobiology: kin selection, altruism, costs and benefits of group-living.
