GATE 2025 Ecology and Evolution (EY) Detailed Syllabus PDF Download

Overview

The GATE 2025 EY paper is a test that checks the knowledge of candidates about the basic concepts in ecology and evolutionary biology. The study material for this exam consists of all the basic and advanced topics in ecological principles to even advanced evolutionary theories. As the breadth of scope covered by this paper is highly extensive, a proper preparation plan has to be undertaken to achieve a good score.

Exam Pattern

Necessary to know the pattern of the exam, and proper preparation: Paper pattern of the GATE 2025 Ecology and Evolution paper deals in detail with the following:

• Type of Questions: This examination will have three types of questions:
• Multiple-Choice Questions (MCQs): In this type, every question has four options with only one correct answer.
• Multiple-Select Questions (MSQs): In such cases, more than one answer can be correct, and the candidate needs to mark all the correct answers.
• Numerical Answer Type Questions: These questions will be attempting numerical problems where the candidate would answer directly in the text box.
• Duration: 3 hours
• Total marks: 100

Distribution of marks:

• General Aptitude 15
• Subject Knowledge (Ecology and Evolution): 85
• Negative Marking: For MCQ there is involved penalty for the wrong answer. One-third marks will be deducted for every wrong answer in a one-mark question and two-thirds marks will be deducted for a two-mark question. MSQ/NAT will carry no negative marking

GATE Ecology and Evolution Syllabus 2025

1. Fundamentals of Ecology

Concepts in Ecology

• Definition and Scope: Knowing the simple definitions of ecology, scope, and importance.
• Levels of Organization: The different levels of biological organization from the organism to the ecosystem.

Ecosystems

• Structure and Function: Ecosystem composition, biotic and abiotic factors, and their functioning.
• Energy Flow: Energy transfer along food chains and food webs. Primary productivity. Trophic levels.
• Nutrient Cycling: Cycles of carbon, nitrogen, phosphorus, and their roles in the ecosystem

Population Ecology:

• Population Dynamics: Growth, density, dispersion, and the limiting factors that determine population numbers
• Growth Models: Logistic and exponential models of growth, carrying capacity, and what it means
• Regulation: Mechanisms of population regulation through predation, competition, disease, etc.

Community Ecology:

• Species Interactions: Predation, mutualism, commensalism, and competition.
• Community Structure: Species diversity, dominance, and community stability.
• Ecological Succession: Primary and secondary succession processes, and elements influencing succession.

Ecosystem Services:

• Economic and Social Classified into Provisioning, regulating, supporting, and cultural services.
• Valuation and Conservation: Quantification of or methods of valuation and measures for conservations of the ecosystem services.

2. Evolutionary Biology

Evolutionary Theory:

• Ancient Views: The establishment by earlier scientists, such as Lamarck and Darwin, and the way evolutionary theory unfolded.
• New Synthesis: Evolutions through the integration of genetics and Darwinian evolution to form a new synthesis.

Genetic Basis of Evolution:

• Mutation: Different types of mutations, causes, and consequences of genetic variability.
• Selection: Natural selection and sexual selection and how they alter the allele frequency.
• Genetic Drift: Role of genetic drift in a small population and impact on genetic diversity.
• Gene Flow: Transfer of genes between populations and their impact on genetic diversity.

Speciation:

• Mechanisms: Allopatric, sympatric, parapatric, and peripatric speciation.
• Types: Study of various speciation events and their consequences.

Evolutionary Ecology:

• Evolutionary Strategies: Life history strategies, r/K selection theory, and trade-offs.
• Adaptation: Mechanisms of adaptation to environmental changes and selection pressures.
• Co-evolution: Interactions between species and their co-evolutionary processes.

3. Biodiversity and Conservation

Biodiversity:

• Definition and Types: Genetic, species, and ecosystem diversity.
• Importance: Roles of biodiversity in ecosystem functioning and human well-being.

Conservation Biology:

• Principles: Key principles of conservation biology, such as the protection of endangered species and habitats.
• Strategies: In situ and ex-situ conservation strategies, protected areas, and conservation planning.
• Policies: International conventions and agreements in the context of conservation.

Threats to Biodiversity:

• Habitat Loss: Causes and consequences of habitat destruction and fragmentation.
• Climate Change: Impacts of climate change on biodiversity and ecosystems
• Invasive Species: How invasive species affect native ecosystems and methods of management.

4. Applied Ecology

Human Impact:

• Urban Ecology: Study of ecological processes in urban environments and their management.
• Agricultural Practices: How agricultural practices affect ecosystems and biodiversity.
• Pollution: Forms of pollution (air, water, soil) and the ecological implications.

Restoration Ecology:

• Principles: Objectives and methodologies for restoring degraded ecosystems
• Practices: Restoration methods and examples of successful ecosystem restorations.

Sustainable Development:

• Concepts: Knowledge of sustainable development objectives and activities
• Applications: Implementation of sustainability principles in different industries such as agriculture, forestry, and urbanization.

5. Quantitative Ecology

Statistical Methods:

• Basic Statistics: Descriptive statistics, distributions, and testing hypotheses.
• Data Analysis: Regression and Correlation Analysis for Ecological Data
• Modeling: Introduction to statistical models and application to ecology

Ecological Modeling

• Simulation Models: simulation models for predicting ecological outcomes
• Population Models: deterministic and stochastic models in population dynamics

Ecological Forecasting: Methods of predicting the future trends and outcomes in ecology

Exam Preparation Tips

• Understand the Pattern of Exam: Familiarize oneself with the structure of the exam and types of questions to tailor study plans accordingly.
• Focus on Core Topics: Focus on the core areas covered in the syllabus. Ensure a great hold of base concepts in both ecology and evolutionary biology.
• Practice Standardized Pattern: Continue to solve question papers and sample tests of previous years to get adjusted to the patterns of questions asked and also time management.
• Refer to Quality Resources: Read from well-known textbooks and scientific journals to understand the subject matter well. Best-suited books include "Ecology: Concepts and Applications" by Manuel C. Molles and "Evolutionary Biology" by Douglas J. Futuyma.
• Stay Updated: Keep an eye on announcements and updates from the official GATE office about any changes to the syllabus or the exam pattern.
• Practice Time Management : It should help you manage your time properly so that you have sufficient time to write the paper when you seat for the exam.

Best Books

• "Ecology: Concepts and Applications" by Manuel C. Molles: This book is an introduction to ecological principles and their practical applications.
• Evolutionary Biology, Douglas J. Futuyma: a thorough overview of evolutionary theory, genetics, and speciation.
• A classic text on the subject and still wholly adherent to elementary facts, "Fundamentals of Ecology" by Eugene P. Odum and Gary W. Barrett, deals with the basics of ecological systems and processes.
• "Conservation Biology: Foundations, Concepts, Applications" by David A. Bowman, et al.: Excellent work with in-depth and broad conservation principles and practices exploration.
• "Quantitative Ecology and Evolution: Insights and Perspectives" edited by David L. H.: This collection presents a wealth of statistical methods and modeling practices in ecology and evolution.
