Study Notes
Autecology (Idioecology) or Individual Ecology
- Autecology studies the characteristics of living organisms, focusing on their adaptations to various environmental factors
- These factors include temperature, humidity, salinity, and other environmental conditions
Plan
-
Organism and Environment:
- Habitat is the part of nature that surrounds a living organism and interacts with it
- Components and properties of the environment vary and are diverse
- Living organisms continually adjust to their environment and adapt vital functions to changes
-
Adaptation of Organisms to the Environment:
- Adaptation is a primary property of life
- It allows for the existence and survival of organisms
- It enables reproduction
-
Environmental Factors:
- Properties or elements influencing organisms are environmental factors.
- Environmental factors are categorized into abiotic and biotic components
-
Law of Optimum:
- Each environmental factor has defined limits for positive effects on organisms.
- The optimum effect of a factor depends on its intensity.
- Insufficient or excessive manifestation of a factor can negatively impact life activity
- Favorable effects occur within the optimum range.
- Deviation from the optimum results in suppressive effects (pessimum area)
-
Shelford's Law of Tolerance:
- Organisms face limiting effects from factors, not only due to absence but also presence (excess)
- Organisms can be characterized by their environmental tolerance limits.
- These limit are denoted as ecological minimum and ecological maximum, forming a tolerance range
-
Law of the Minimum:
- This law, formulated by Liebig, describes how the organism's endurance is determined by the weakest link in the environmental chain.
-
Anthropogenic Factors:
- These are human societal activities that alter natural environments
-
Biotic Factors:
- Biotic factors refer to interactions between living organisms.
-
Abiotic Factors:
- Abiotic factors are components of inanimate nature influencing living organisms.
- These encompass physical (e.g., space, climate) and chemical factors (e.g., soil composition, water, air, pH).
-
Climatic Factors:
- Radiant solar energy, humidity, precipitation, and ventilation (wind) impact living organisms.
-
Chemical Factors:
- Soil components, water, air, pH, and impurities are chemical factors.
-
Examples of Anthropogenic Impacts:
- Hunting, agriculture, industry, and transportation have significantly changed the planet.
- Deforestation is a harmful result of human activity.
- Domestication of wolves (e.g., dogs) changed their lifestyles but not necessarily harmed them.
-
Stenobionts and Eurybionts:
- Stenobionts have narrow ranges of tolerance for various environmental factors
- Eurybionts have wide ranges of tolerance for various environmental factors
-
Maximum Permissible Concentration (MPC)
- MPC defines the limit of existence for various plants and animals through experimentation.
- It is grounded in tolerance limits identified through ecological experiments .
-
Limiting Factors:
- Factors limiting the life of organisms are called limiting factors
- Limiting factors can include insufficient or excess of an essential factor.
- Sufficient amounts of essential factors (such as potassium, sodium, and phosphorus, along with microelements like copper) are required for plant growth
