Study Notes
Philippine Biodiversity Status
- The Philippines is one of 17 megadiverse countries globally, with over 52,000 described species.
- Half of these species are endemic, meaning they're found nowhere else.
- The archipelago's islands are characterized by high endemism for both plants and animals.
- From 1997 to 2016, over 300 new species of plants and animals were discovered.
Ecosystem Uniqueness and Factors
- Ecosystem uniqueness comes from a specific combination of factors.
- Abiotic factors include climate, soil type, and water availability.
- Biotic factors involve the kinds of organisms present, their relationships, and their adaptations.
Key Biodiversity Areas (KBAs)
- The KBA approach is used to prioritize conservation in the Philippines.
- Important Bird Areas (IBAs) and Conservation Priority Areas (CPAs) are used as a basis for identifying KBAs.
Taxonomy
- Taxonomy involves classifying and naming all living organisms in the world, including plants, animals, and microorganisms (prokaryotes and eukaryotes).
Philippine Biodiversity Benefits
- Ecosystem services are positive benefits that wildlife and ecosystems provide to people, these can be direct or indirect. (small or large)
- Provisioning services: food, materials, and other tangible goods.
- Regulating services: managing natural processes such as climate, flood, and water.
- Cultural services: impacting human well-being through recreation, education, spirituality
- Supporting services: enable ecosystems to function, nutrient cycling, soil formation, and biodiversity support.
Effects of Biodiversity Loss on Human Health
- Biodiversity loss impacts health in various ways, which includes the loss of life from genetic diversity to entire ecosystems collapse.
- Emerging infectious diseases are connected to human-induced changes like deforestation, extractive industries, and urban development.
- Food insecurity and malnutrition may be connected to biodiversity loss.
Philippine Population Growth
- Population growth in the Philippines has been significant (due to high fertility rates and urbanization).
- Population growth has implications like increased pressure on resources, urban overcrowding, and economic and environmental strains.
Population Distribution
- Three types of population distribution are:
- Uniform: Spacing organisms evenly
- Random: Randomly scattered
- Clumped: Organisms clustered together.
Agricultural Density
- Agricultural density examines the amount of farmers per unit of arable land.
- Higher agricultural density suggests more reliance on manual labor for food production, lower density suggests more efficient use of technology.
Climate Change and Global Warming
- Climate change causes shifts in temperature and weather patterns.
- This can have results in changes in species distribution and biodiversity.
- Human activities are a major driver of climate change.
