Key Ecological Concepts and Definitions
- Autoecology: Studies individual species and their interactions with other species and their environment.
- Synecology: Studies ecological communities and their relationships with the environment.
- Biome: A large community of plants and animals with similar life forms and environmental conditions, often characterized by dominant plant types and climate.
- Biological Community: Also known as a biocenosis, it is the group of organisms of all species (bacteria, protozoa, fungi, plants, and animals) that coexist in a specific place, called a biotope.
- Ecosystem: According to Tansley's original definition (1935), an ecosystem is a biological community (biocenosis) together with its physical environment (biotope), as defined by many ecologists.
- Population: A group of organisms of the same species that interact with each other and live in a particular geographic area within a given time.
- Habitat: The place a species occupies within the physical space of a community.
- Ecological Niche: The role a species plays within its community, for example, as producers, herbivores, or carnivores.
Understanding Sustainable Development
Sustainable development is defined as development that satisfies current needs without compromising the ability of future generations to meet their own needs.
Dimensions of Sustainable Development
| Dimension | Description |
|---|---|
| Social Dimension | Refers to social peace and the basic services that an organized society must fulfill, such as security, employment, urban development, adequate population growth, gender equity, and positive availability of schools and public services accessible to the whole society, as well as ensuring a high educational level for everyone. |
| Economic Dimension | Refers to the possibility of continuous economic growth through the rational use of natural resources that does not involve their depletion or environmental degradation in the short and long terms. |
| Ecological Dimension | Refers to the maintenance of life-supporting systems by caring for ecosystems through the rational and sustainable use of resources to preserve genetic diversity. |
