Study Notes
What is Ecology?
- Scientific study of interactions between organisms and their environment.
- Originates from Greek words: "Oîkos" (house) and "λογία" (-logia) (study of life).
- Aims to describe the relationships between living organisms (biotic) and their environment (abiotic).
Factors of Ecology
- Abiotic Factors: Non-living components like light, temperature, water, atmosphere, nutrients, and heat.
- Biotic Factors: All living organisms including plants, animals, and microorganisms in a habitat.
History of Ecology
- The term "Ecology" was coined by Ernst Haeckel in 1866.
- Danish botanist Eugenius Warming expanded on the concept of Ecology.
Classification of Ecology
- Ecophysiology: Studies how physiological functions of organisms affect their environmental interactions.
- Behavioral Ecology: Examines animal behavior and adaptation to environments.
- Population Ecology: Analyzes dynamics of populations for a single species.
- Community Ecology (Synecology): Focuses on species interactions within ecological communities.
- Ecosystem Ecology: Investigates energy and matter flows in ecosystems.
- Systems Ecology: Interdisciplinary approach studying ecological systems holistically.
- Landscape Ecology: Studies processes across multiple ecosystems or large geographic areas.
- Evolutionary Ecology: Considers evolutionary histories of species and their interactions.
- Political Ecology: Links political and economic issues to environmental control and ecological change.
Levels of Ecology
- Biosphere: Total global surface of Earth inhabited by living organisms.
- Region: Groups of ecosystems sharing the same climate and communities.
- Landscape: Collections of interacting ecosystems in a specific area.
- Ecosystem: Communities and populations within a common environment.
- Community: Different species populations interacting in a specific area.
- Population: Individuals of the same species in a particular geographic area.
- Individual: Single organisms capable of breeding and producing fertile offspring.
Types of Ecosystems
- Tropical Forest: Vertical stratification; canopy trees block light to lower strata; epiphytes present.
- Desert: Very low rainfall (<30 cm/year) with adaptations for water conservation; can vary in temperature extremes.
- Coniferous Forest: Largest terrestrial biome; old growth forests diminishing; abundant moisture.
- Tundra: Characterized by permafrost; bitter cold and high winds; no trees present.
Ecosystem Dynamics
- An ecosystem is a complex interaction of plant, animal, microorganism communities, and their abiotic environment, functioning as a unit.
- Dynamic ecosystems maintain ecological balance.
Current Status of Ecology
- Past Status: Ecosystems were stable, undisturbed by human activity.
- Present Status: Increasing human population is impacting ecosystems, leading to ecological crises.
Ecological Crisis
- Main causes include:
- Overpopulation: Depletion of resources caused by excessive population density.
- Environmental Pollution: Harmful contaminants affecting air, water, and land.
- Deforestation: Destruction of forests leading to loss of biodiversity and habitat.
Hydrologic Cycle
- Example of a dynamic ecosystem highlighting interactions between living organisms and water systems.
