Study Notes
Ecology
- Theophrastus authored "Enquiry into plants"
- Oikos means "household" in the Greek word "ecology"
- Logos refers to "study" in the Greek word "ecology"
- Ecology is the scientific study of the interactions between organisms and their environment
- Alexander von Humboldt is known as the "father of biogeography"
- Traits such as size, and speed are influenced by fitness which is environment-specific and species-specific; measured across generations
- Natural selection operates on variations, survival of the fittest and reproduction
- Selection occurs in forms of direction, disruptive, stabilizing and stochastic
- Interactions that determine the distribution and abundance of organisms are the focus of ecology
Hierarchy and Evolution
- Hierarchical structures are stable as they emerge from various evolutionary processes.
Cell Biology
- The mitochondrion is a sub-cellular organelle.
Ecological Research
- The laboratory approach to ecology uses experiments.
Biodiversity
- Beta (β) biodiversity refers to the diversity that exists among different geographies.
- Alpha (α) biodiversity refers to the diversity that exists within an ecosystem.
Systems of Classification
- The hierarchical system was given by Humboldt.
- A species is defined as "groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups".
Emergent Principles
- The emergent principle states that Whole > sum of parts.
Biodiversity and Competition/Predation
- There is more biodiversity in areas with less competition, less predation.
