Study Notes
Ecology and Human Interaction
- Ecology is the study of the economy, household, and organisms.
- Ecosystem models the cycle of energy and matter, including organic and inorganic entities.
- Organisms depend on energy and matter.
- Ecosystems describe how human populations influence and are influenced by their surroundings.
Ecosystem Stability
- Resilience measures a system's ability to change while maintaining its basic elements and relationships.
- Stability measures how quickly a system returns to equilibrium after disturbances.
- Systems with high resilience but low stability may experience continual change.
- Systems with high stability but low resilience may show little change in response to disturbances but can collapse suddenly.
Types of Ecosystems
- Natural Systems: Not noticeably altered by humans. Ecosystems such as mountains, lakes, and primeval forests are examples.
- Semi-natural Systems: Ecosystems altered by human activities but retaining significant natural elements. Examples include areas with traditional agricultural forms.
Artificial Ecosystems
- These are human-made systems with plants, animals, and people.
- Examples include zoos with artificial ecosystems replicating natural habitats.
Human Systems
- Families are the fundamental social unit with associated relationships.
- Organizations, random groups, or carefully constructed groups address short or long-term needs.
- Communities are the theory of relationships helping local populations meet daily requirements.
Ecosystem Models and Approaches
- Ecosystem-based models focus on the relationship between human populations and ecosystems.
- Social systems interact with the ecosystem and receive inputs from it.
- The human ecosystem model involves critical resources (biotic and abiotic), social systems, and their interactions.
Climate Change
- Climate change is a systematic change in the atmospheric conditions over multiple decades or more.
- Natural variation in climate occurs over months to decades.
- Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and black carbon, released during the Industrial Revolution caused and are causing climate change.
Climate Change Impacts
- Surface and ocean temperatures are rising.
- Glaciers and snowpack are losing mass.
- Sea levels are rising.
- Increased extreme weather events (storms, floods, droughts).
- Ocean acidification due to increased carbon dioxide absorption.
Adaptation and Vulnerability
- Adaptation is the ability of a system to adjust to climate change.
- Vulnerability is the system's predisposition to being negatively affected by climate change.
- Adaptive capacity is a system's ability to anticipate, recover, respond, and recover from threats.
- Factors influencing adaptive capacity include access to information, resources, flexibility, and willingness to adapt.
- Vulnerability assessments consider sensitivity and exposure in addition to adaptive capacity.
