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.
