Study Notes
Ecology Overview
- Ecology is the scientific analysis and study of interactions among organisms and their environment, including abiotic factors.
- Ecology is interdisciplinary, encompassing biology and Earth science.
- The term "ecology" was coined by Ernst Haeckel in 1866.
- Ecology studies interactions between organisms and their environment.
Ecological Development
- Ecology seeks to explain why certain organisms compose communities, how organisms interact, and how to maintain those communities.
- Ecological processes include the movement of materials and energy, ecosystem development, and organism distribution and biodiversity.
- Ecology highlights the interdependence between the natural world and human activities.
Objectives of Ecology
- A key objective is understanding how biotic elements of an ecosystem interact and depend on one another.
- Ecology also studies the interactions between biotic and abiotic components of ecosystems.
- Other objectives include studying the relationships between organisms within ecosystems, the effects of environmental change on organisms, and changes in organism behavior and adaptations.
Importance of Ecology
- Ecology provides scientific foundations for agriculture, forestry, and fisheries, aiding understanding of resources and their distribution.
- It helps to determine organism distribution and abundance over earth's surface.
- Understanding the consequences of environmental interventions, like dams and river diversions, is crucial.
- It underpins biological conservation and helps predict, prevent, and remedy pollution.
- A better understanding of ecosystems aids in comprehending global and regional competition for resources.
Divisions of Ecology
- Autecology: Focuses on the ecology of a single species and its interaction with other organisms and its environment at different stages of its life cycle.
- Synecology: Deals with the ecology of communities. It includes the study of community structure, nature, organization, and development.
Basic Ecological Terms
-
Population: A group of organisms of the same species in a given area.
-
Community: A group of different species interacting in a particular area forming a complex web of relationships.
-
Habitat: Physical place where an organism lives or is found.
-
Ecosystem: A functional unit of ecology containing a self-sustaining community of interacting organisms with their non-living environment.
-
Ecological Niche: Combines the spatial habitat and functional role of an organism in a community.
-
Biosphere: All ecosystems on Earth and their interconnected relationships, the largest ecological scale.
-
Biome: A large geographical area defined by distinct life forms, especially the dominant type of vegetation and adapted to a particular set of living conditions.
-
Environment: Includes the physical, social (human), and built world influences affecting organisms.
-
Biogeochemical Cycles: Cyclical movement of materials/nutrients through different points in an ecosystem. Energy is recycled and not lost.
-
Ecological Interactions: Relationships among organisms (e.g., competition, predation, mutualism).
-
Ecological Succession: Process of gradual change in an environment where organisms occupy the area and gradually change the conditions allowing other species to move in.
-
Trophic Levels: Feeding levels in an ecosystem (e.g., producers, herbivores, carnivores)
Ecological History and Development
- Key figures and their contributions to ecological understanding are discussed, including their discoveries and developments in understanding natural processes.
Levels of Ecological Study
- Various levels of study, from global processes to organismal interactions, are examined. These include:
- Global ecology
- Landscape ecology
- Ecosystem ecology
- Community ecology
- Population ecology
- Organismal ecology
- Molecular ecology
Hierarchical Structure of Ecological Systems
- Organisms, populations, communities, ecosystems, biomes, and the biosphere are explained.
- Ecology focuses on these hierarchical relationships.
