Study Notes
Conservation of Biodiversity
- Conservation biology aims to protect and manage Earth's biodiversity by combining principles from ecology, biology, genetics, and other natural sciences.
- Key goals of conservation biology include understanding biodiversity, assessing threats, developing conservation strategies, sustainable use of resources, and education and advocacy.
Threats to Biodiversity
- Overexploitation of organisms leads to population decline, ecosystem imbalance, economic and livelihood consequences, and extinction.
- Examples of overexploitation include overfishing, hunting and poaching, logging and timber harvesting, wildlife trade, and medicinal and ornamental plants.
Strategies to Combat Overexploitation
- Sustainable harvesting practices, protected areas, monitoring and enforcement, community involvement, and public awareness are strategies to combat overexploitation.
Invasive Species
- Invasive species, also known as exotic or non-native species, are introduced to new environments through human activities such as trade, travel, agriculture, and aquaculture.
- Invasive species can cause harm to the environment, economy, or human health.
Impacts of Invasive Species
- Impacts of invasive species include biodiversity loss, habitat alteration, ecological imbalance, human health, and economic costs.
Management and Control
- Restoration, early detection, and rapid response, biological, mechanical, and chemical alteration are methods for managing and controlling invasive species.
Pollution and Degradation
- Pollution is the introduction of harmful materials into the environment, causing harm to humans or the environment.
- Different types of pollution include water pollution, air pollution, radioactive contamination, chemical pollution, noise pollution, and light pollution.
Habitat Alteration and Loss
- Habitat alteration refers to changes in natural environments that organisms depend on for survival.
- Habitat loss refers to the complete destruction of a habitat, rendering it unable to support the species that once lived there.
- Human activities such as urbanization, agriculture, deforestation, pollution, infrastructure development, and climate change contribute to habitat alteration and loss.
Strategies to Mitigate Habitat Alteration and Loss
- Public awareness, climate action, land-use planning, and protected areas are strategies to mitigate habitat alteration and loss.
