C.1.1: Survival Factors
-
-
Plant & Salinity
Salinity Dependency
Glycophytes
- Not salt tolerant
- Easily damaged by high salinity
Halophytes
- Salt tolerant
- Become stressed in freshwater
-
Coral & Temperature
Zooxanthellae (Algae)
Coral polyps receive nutrients from algae
- Lives within polyp's endodermis
The algae cannot survive in cold
Algae leaves coral tissue at too high temperature
- Coral bleaching
- Above 35 degrees C
Reefs Building Corals
Typical optimal growth range
- 20 to 30 degrees C waters
Tropical and sub-tropical regions
- Intraspecific: Within species
- Interspecific: Between species
- Light
- Temperature
- Salinity
- Rainfall
- Wind velocity
- Soil pH
- Central portion with conditions favouring maximal reproductive success and survivability
- Regions flanking optimal, organisms can survive with reduced reproductive success
- Outermost regions, no survival and extremes of limiting factors
