In this third lecture on Ecology and Environment, we delve into key ecological concepts critical for UPSC Civil Services Examination and other competitive exams. Understand the concepts of Ecotone, Edge Effect, Edge Species, and Ecological Niche with clarity. Key Topics Covered Ecotone: Definition: Transitional area between two diverse ecosystems. Examples: Mangroves (between marine and terrestrial ecosystems). Grasslands (between forests and deserts). Estuaries (between freshwater and saltwater ecosystems). Characteristics: Can be narrow or wide. Intermediate conditions of adjoining ecosystems. High species diversity and population density. Eco Cline: Gradual and continuous change between two ecosystems. Influenced by abiotic factors like altitude, temperature, salinity, and depth. Example: Gradual transition from forest to desert. Edge Effect & Edge Species: Edge Effect: Changes in population or community structure at the boundary of two habitats. Edge Species: Species that thrive primarily in ecotones (e.g., birds in terrestrial ecotones). Examples: Mangroves hosting unique species not found in terrestrial or marine ecosystems. Ecological Niche: Definition: Unique functional role and position of a species in its habitat. Types: Habitat Niche: Where it lives. Food Niche: What it eats. Reproductive Niche: How and when it reproduces. Physical/Chemical Niche: Environmental requirements like temperature and humidity. Difference Between Habitat and Niche: Habitat: Physical space or address of a species. Niche: Unique functional role or "profession" in the ecosystem. Importance for Conservation: Knowledge of niche helps preserve species in native habitats. UPSC Prelims Question on Niche: Question: Which term describes both physical space and functional role in a community? Answer: Ecological Niche. Why Watch This Lecture? Simplified and detailed explanations of complex ecological concepts. Ideal for UPSC Prelims GS Paper 1 and Mains GS Paper 3 (Environment and Ecology).
