Biodiversity Flashcards
Is the diversity of genes, species, and ecosystem in a region
Biodiversity
3 types of diversity
✓Diversity of genes
✓Diversity of species
✓Diversity of ecosystem
Is the death of a species, the elimination of all individuals of a species
Extinction
3 benefits of bio diversity
- Ecological services benefits
- Aesthetic benefits
- Cultural benefits
Some species are prone to be extinct by their own characteristics
Extinction by the nature
Least likely to be extinct if:
• High population density
• Found over large area
• Generalized niche
• High reproductive rate
Most likely to become extinct if:
• Low population density
• Found in small area
• Specialized niche
• Low reproductive rate
Threath to species by human activities
HIPPO
• Habitat destruction
• Introduction of invasive species
• Pollution and population growth
• Overharvesting
Example of Habitat destruction
• Destroy the forest
• Mining
• Climate Change
Are those species that could become extinct if critical factors in their environment are changed continuously
Threatened species
A biographic region with a rich biodiversity including endemic flora and fauna, that is also threatened with destruction
Biological hotspot
3 Ways to sustain biodiversity
✓ Establish and protect wilderness area, park, and nature preserves
✓ Identify and protect biological hotspots
✓ Restore damaged ecosystem
5 ways in restoring damaged ecosystem
- Removing physical stressors: pollutants, vehicle traffics, inadequate water supply
- Controlling invasive species
- Replanting
- Captive breeding and reestablishing fauna
- Monitoring
Are those species that present in small number that they are in immediate jeopardy of becoming extinct species
Endangered species
Examples of endangered species
- White rhino
- Leopard
- Panda
