Study Notes
Ecological Range of Tolerance
- Defines conditions like temperature, salinity, pH, or sunlight that organisms can withstand before suffering injury or death.
- Both species and individual organisms have distinct ranges of tolerance for various environmental conditions.
Example of Ecological Range of Tolerance
- Salmon exhibit a basic temperature tolerance range from 6°C to 22°C.
- Certain individual salmon may have adaptations allowing them to tolerate conditions beyond this species-specific range.
Optimal Range
- The optimal range is the specific set of conditions where organisms can survive, thrive, grow, and reproduce effectively.
Zone of Physiological Stress
- A transitional range where organisms can survive but face stress, leading to issues such as infertility, stunted growth, and reduced activity levels.
Zone of Intolerance
- Represents conditions that lead to the death of organisms.
- Examples of intolerant conditions include thermal shock, suffocation, and scarcity of essential resources like food, water, or oxygen.
Limiting Factors
- Identifies the environmental factor most limited in supply, which regulates population growth despite other factors being optimal.
Soil Nutrients
- Critical nutrients in soil often include nitrogen, phosphorus, and potassium, leading to the use of NPK testing kits and the formulation of fertilizers.
Open Ocean Nutrients
- Key limiting nutrients can include nitrogen, silica, iron, or dissolved oxygen (DO) in marine environments.
Freshwater Nutrients
- Phosphorus often serves as a limiting nutrient for lakes and rivers, influencing aquatic ecosystems.
Bays and Estuaries
- Salinity is a crucial factor in these environments, affecting the ecological balance and species presence.
