1. Population Ecology:

  • Study of populations and their interactions in a specific area.

  • Key attributes include population size, density, and dispersion patterns.

  • Models like exponential and logistic growth explain population dynamics.

  • Factors influencing population growth are discussed.

2. Population Interactions:

  • Explores interactions (competition, predation, mutualism, etc.) among populations in ecosystems.

  • Understanding interactions is crucial for comprehending ecological relationships and community dynamics.

3. Biodiversity and Conservation:

  • Biodiversity encompasses genetic, species, and ecosystem diversity.

  • Factors leading to biodiversity decline: habitat destruction, overexploitation, pollution, invasive species.

  • Conservation strategies include protected areas, species conservation, and sustainable resource management.

4. Population Attributes:

  • Attributes like age distribution, sex ratio, birth rate, death rate, and life expectancy provide insights into population structure.

  • Concepts like carrying capacity and environmental resistance explain population limitations.

5. Adaptations:

  • Adaptations are traits aiding survival and reproduction.

  • Three types: structural, behavioral, physiological.

  • Adaptations enhance fitness and species success in specific habitats.

6. Significance of Diversity:

  • Biodiversity is vital for ecosystem functioning and stability.

  • Diverse ecosystems are more resilient to environmental changes.

  • Conservation is essential to maintaining ecological balance and future well-being.
