GATE Ecology and Evolution Syllabus 2021 – EY Chapters, Topics


GATE Ecology and Evolution Syllabus 2021 : Check out the latest GATE Syllabus for Ecology and Evolution (EY). Ecology and Evolution subject is the one of the papers in GATE 2021 Exam. Earlier we’ve provided GATE Exam pattern 2021, Now we are providing GATE Syllabus 2021 of Ecology and Evolution Paper. EY is the subject code of GATE Ecology and Evolution Exam. Below we’ve provided GATE Ecology and Evolution Syllabus and weight-age for GATE 2021 Exam. Here you can see Ecology and Evolution applicable chapters and topics for GATE exam 2021.

GATE Paper Pattern & Marks Weightage

GATE paper questions are divided into three sections.  As given below GATE marks are distributed for each section. 70% of the marks covers the core subject of the GATE Exam. i.e here Core Subject is Ecology and Evolution.

GATE Ecology and Evolution Syllabus 2021

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;

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.

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.

Section 4: Behavioural Ecology

Classical ethology; neuroethology; evolutionary ethology; chemical, acoustic and visual signaling

Sensory ecology: Neuroetholgy, communication (acoustic, chemical, and visual signaling); recognition system.

Foraging ecology: Foraging behaviour; optimal forgaging theory

Reproduction: Cost of sex. sexual dimorphism; mate choice; sexual selection (runaway selection, good-gense, handicap priciples, etc); sexual conflict, mating systems, parents care

Social living: Costs and benefits of group-living (including responses to predators); effect of competition (scramble and contest) on group formation; dominance relationship; eusociality; kin selection, altrusim; reciprocity; human behaviour

Section 5: Applied Ecology  & Evolution

Biodiversity and Conservation: Importance of conserving biodiversity; econsyste services; threats to biodiversiy; 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: Epidemology, Zoonotic diseases; antibiotic resistance; vector control

Plant and animal breeding: genetic basis of economically, maker assisted.

Globa elimate change: Causes; consequences; mitigation
