Study Notes
Biodiversity Levels
- Genetic biodiversity refers to individual genetic variation within a population and between populations.
Species Extinction
- Local extinction of a species is also known as extirpation.
Conservation Status Assessment
- The organization that assesses the conservation status of species in Canada and makes recommendations to the federal government is not specified.
Human-Induced Global Changes
- Ozone depletion is not a global change brought about by humans.
Fragmented Habitats
- Movement corridors are used to connect fragmented habitats, allowing species to migrate and maintain genetic diversity.
Toxic Chemicals
- Biomagnification is the process by which toxic chemicals build up within predators.
Natural Reserves
- Approximately 12% of the world's land has been established as natural reserves.
Greenhouse Gas Emissions
- Nuclear power generation is not a source of greenhouse gas emissions.
Ozone Depletion
- The main cause of ozone depletion is the presence of chlorofluorocarbons (CFCs) in the atmosphere.
Montreal Protocol
- The Montreal Protocol aims to reduce the production and consumption of ozone-depleting substances.
Sustainable Development
- Sustainable development is a development model that meets the needs of the present without compromising the ability of future generations to meet their own needs.
Threats to Biodiversity
- Habitat destruction and fragmentation are considered the single greatest threat to biodiversity.
Global Environmental Changes
- Global environmental changes involve alterations in broad ecological systems, atmospheric chemistry, climate, and ozone depletion.
Landscape Ecology
- The goal of landscape ecology is to understand the dynamics of spatial patterns and processes in landscape mosaics.
IUCN Red List
- The IUCN Red List is used to classify species based on their conservation status, providing a global standard for measuring the extinction risk of species.
