Detailed GATE Ecology and Evolution Syllabus 2023
The core subject of the GATE Ecology and Evolution (EY) syllabus comprises 85% of the exam marks while the rest 15% is from the General Aptitude section. The Ecology and Evolution syllabus is broadly divided into five main sections which are mentioned below.
- Mathematics and Quantitative Ecology
- Behavioural Ecology
- Applied Ecology and Evolution
Further, let us now discuss in detail the topics included in these sections.
GATE EY Syllabus-Ecology
The Ecology section of the GATE Ecology and Evolution syllabus consists of various important topics such as population ecology, ecophysiology, theory of island biogeography, etc. Let us discuss these topics in detail.
- Fundamental Concepts: Scales (species, population, ecosystem, biomes, community), Abiotic and biotic components, habitats, and niches.
- Population ecology: Metapopulation ecology (colonization, persistence, extinction, patches, sources, sinks); Population growth rates (density-dependent/independent); age-structured populations.
- Interactions: Prey-predator interactions, Types (mutualism, symbiosis, commensalism, competition, parasitism, predation, etc), ecophysiology (physiological adaptations to the abiotic environment).
- Ecosystems structure and function: Trophic levels and their interactions, nutrient cycles; primary and secondary productivity.
- Community ecology: Species-area relationships, Community assembly, theory of island biogeography, organization and succession; species richness, evenness and diversity indices.
GATE EY Syllabus-Evolution
The Evolution section of GATE EY syllabus 2023 consists of various important topics such as iteroparity, allocation of resources, drift, Hardy- Weinsberg equilibrium, etc. Further, let us check these topics mentioned in the table below.
History of Evolutionary thought
Lamarckism; Darwinism; Modern Synthesis.
Variation; heritability; natural selection; fitness and adaptation; types of selection (stabilizing, directional, disruptive).
Diversity of Life
Origin and history of life on earth; diversity and classification of life; systems of classification (cladistics and phenetics).
Life history strategies
Allocation of resources; trade-offs; r/K selection; semelparity and iteroparity.
Coevolution (co-adaptations, arms race, Red Queen hypothesis, co- speciation); prey-predator interactions (mimicry, crypsis, etc).
Population and Quantitative genetics
Origins of genetic variation; Mendelian genetics; Hardy-Weinberg equilibrium; drift; selection (one-locus two-alleles model); population genetic structure (panmixia, gene flow, FST); polygenic traits; gene-environment interactions (phenotypic plasticity); heritability.
Species concepts and speciation; adaptive radiation; convergence; biogeography.
Molecular evolution and phylogenetics
Neutral theory; molecular clocks; rates of evolution; phylogenetic reconstruction; molecular systematics.
GATE EY Syllabus-Mathematics and Quantitative Ecology
The Mathematics and Quantitative ecology section of GATE Ecology and Evolution syllabus 2023 consists of various important topics from Statistical hypothesis testing and Mathematics in ecology sections. Let us discuss these topics in detail.
- Mathematics and statistics in ecology: Simple functions (linear, quadratic, exponential, logarithmic, etc); the 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.
GATE EY Syllabus-Behavioural Ecology
The Behavioural ecology section of GATE Ecology and Evolution syllabus 2023 comprises various important topics such as Neuroethology, mating systems, imprinting, reciprocity, etc. Let us discuss these topics in the table mentioned below.
Instinct; fixed action pattern; imprinting; learned behavior; proximate and ultimate questions.
Neuroethology; communication (chemical, acoustic and visual signaling); recognition systems.
Foraging behaviour; optimal foraging theory,
Cost of sex; sexual dimorphism; mate choice; sexual selection (runaway selection, good genes, handicap principle, etc); sexual conflict; mating systems; parental care.
Costs and benefits of group-living (including responses to predators); effect of competition (scramble and contest) on group formation; dominance relationships; eusociality; kin selection; altruism; reciprocity; human behaviour.
GATE EY Syllabus-Applied Ecology and Evolution
The Applied Ecology and Evolution section of GATE EY syllabus 2023 consists of the following topics- Biodiversity & conservation, plant & animal breeding, global climate change, and disease ecology & evolution. Let us discuss these topics in detail.
- Biodiversity and conservation: Importance of conserving biodiversity; ecosystem services; threats to biodiversity; invasive species; in-situ conservation (endemism, biodiversity hotspots, protected areas); ex-situ conservation; conservation genetics (genetic diversity, inbreeding depression); DNA fingerprinting and DNA barcoding.
- Disease ecology and evolution: Epidemiology; zoonotic diseases; antibiotic resistance; vector control
- Plant and animal breeding: Marker-assisted breeding; genetic basis of economically important traits
- Global climate change: Causes; consequences; mitigation.
