Study Notes
Theoretical Approach in Ecology
- Focuses on developing frameworks and equations to model ecological systems.
- Utilizes mathematical models to understand how populations interact.
- Involves defining relationships like how prey population (p) is influenced by both the predator population (P) and the existing prey population.
- One example of this approach is using the Lotka-Volterra equations to model predator-prey dynamics.
Laboratory Approach in Ecology
- Utilizes the scientific method, focusing on hypothesis formation and testing.
- Employs experiments to validate ecological theories and understand ecological processes.
- Involves analyzing factors that impact organism abundance and distribution.
Example: Limiting Factors in a Pond
- Example investigates why an algae population is low in a pond.
- The low abundance of algae suggests the presence of limiting factors.
- The laboratory approach would involve conducting experiments to identify these limiting factors.
- The specific limiting factors may include nutrients, temperature, or light availability.
Illustration of Pond
- Depicts a pond divided into eight sections.
- Each section represents a parameter influencing the ecological system in the pond.
- Possible parameters include temperature, nutrient levels (nitrogen, phosphorus), and other factors influencing algae abundance.
- The "Control" circle likely represents a baseline or reference point for comparison.
