BIODIVERSITY/PAIC/FAUNAL REGION Flashcards
- Variety of Life
-described in terms of niche, food intake, interaction, morphology, genetic material, distribution and abundance.
Biodiversity
- Number of Organism
- Distribution and Abundance
Diversity of Ecosystem
- describing phenotype/ morphological/ genotype
Diversity in Genetic Level
- a geological and biological concept that explains the unique biodiversity of the Philippines.
Pleistocene Aggregate Island Complex (PAIC)
3 Key Point about PAIC
- Formation
-Isolation
-Biodiversity
During ice ages, vast amounts of water were locked up in glaciers, causing sea levels to drop dramatically. This connected numerous islands into large landmasses.
FORMATION
As sea level rose again in the end of ice ages, these land masses were isolated, leading to the formation of distinct ecological and geological barriers
ISOLATION
This process of isolation and subsequent reconnection created ideal conditions for species diversification, resulting in Rich ______ found in the Philippines today
BIODIVERSITY
Impact of Biodiversity (PAIC)
- High Levels of Endemism
-Complex Patterns of Distribution
-Rapid Speciation
Evolution of Plants and Animals found only in the Philippines due to the isolation on these former larger islands
HIGH LEVELS OF ENDEMISM
Distribution of Species across the Archipelago reflects the historical connection and separation of PAIC’s
COMPLEX PATTER OF DISTRIBUTION
The repeated cycles of isolation and reconnection accelerated the formation of new Species
RAPID SPECIATION
Geographical Areas characterized by distinct Animal Life. These regions are defined based on the unique species found within them, as well as their evolutionary history and ecological adaptation.
FAUNAL REGIONS
Faunal Regions is also known as ______
ZOOGEOGRAPHIC REGIONS
Key Factors in identifying faunal regions in the Philippines.
- Geographic Barriers
-Pleistocene Aggregate Island Complex (PAIC)
-Endemic Species
-Genetic Analysis
