biodiversity Flashcards
bio means?
life
diversity equals?
variety
Is the variety of life on Earth and the essential interdependence of all living things
Biodiversity
3 components of biodiversity
Ecological/Ecosystem Diversity
Species Diversity
Genetic Diversity
found in warm tropical waters above the continental shelf
Coral Reefs
Changes greatly between its source and its mouth
A river environment
the richest biomes in terms of species diversity
Wetlands
Reflect regional variations in climate
Terrestrial biomes
Grasslands with scattered trees
Savannas
Drier, tropical areas are characterized by the savanna
Defined by their dryness
- Driest of all terrestrial biomes
Deserts
Spiny shrubs dominate the?
Chaparral
Is a shrubland with cool, rainy winters and dry
Chaparral biome
Found in the interiors of the continents, where winters are cold
Temperate grasslands
grow where there is sufficient moisture to support the growth of large trees
Temperate deciduous forests
Largest terrestrial biome on earth
Coniferous forest (taiga)
Characterized by long, cold winters and short, wet summers
Taiga
It is a treeless biome characterized by extreme cold, wind, and permafrost
The artic tundra
Importance of biodiversity
Medicine
Air and water purification
Pollination and seed dispersal
Economic/ cultural value
Drought, erosion and flood control
Threats to biodiversity
Habitat destruction
Pollution
Species Introductions
Global climate change
Exploitation
One of the 18 countries identified as containing 70% of the world’s biodiversity
Philippines
Any species which are vulnerable to endangerment in the near future
Threatened Species
Treats threatened Species not as a single category, but as a group
The World Conservation Union (IUCN)
is used to refer to the least at risk of those three categories
Vulnerable Species
refer to the more at risk categories of threatened species
Endangered and critically endangered
Threats to Philippine Biodiversity
A. Habitat Destruction
B. Over- Exploitation
C. Chemical or Environmental Pollution
D. Biological Pollution
Approaches to biodiversity conservation ans management
- IN-SITU Approaches
- EX-SITU Approaches
- Restoration and Rehabilitation
- Major Land Use
- Policy Institutional
