Study Notes
Intertidal Zone Overview
- The intertidal zone is the coastal area immersed underwater during high tide and exposed to air during low tide.
- It experiences varying conditions due to tidal movements and wave action.
Characteristics of the Intertidal Zone
- Covered with water at high tide, providing a marine environment.
- Exposed to dry air at low tide, creating unique survival challenges for organisms.
Types of Intertidal Zones
- Sandy shore: Composed primarily of sand, offering different habitats and species.
- Rocky shore: Characterized by solid rock, hosting various organisms adapted to harsh conditions.
Influencing Factors
- Waves and tides are the main factors impacting the intertidal zone, affecting habitat dynamics and organism availability.
Tides
- Tides result from the gravitational pull of the moon and sun combined with Earth's rotation, causing the sea to alternate between rising and falling.
Splash Zone
- This area is where waves crash during high tide, affecting organisms' survival and habitat structure.
Rocky Shores
- Rocky shores are intertidal zones dominated by solid rock, serving as a habitat for diverse marine life.
Rocky Intertidal Zone Example
- Tide pools are found in rocky intertidal areas, providing unique ecosystems.
Organism Types
- Organisms in the intertidal zone are primarily marine, as opposed to freshwater.
Biomass in the Intertidal Zone
- High biomass indicates abundant food sources resulting from photosynthesis and nutrient availability.
Nutritional Dynamics
- High sunlight levels and the presence of nitrates and phosphates support high levels of algae growth, crucial for the food web.
Wave Impact
- Organisms not attached to surfaces can be adversely affected by wave action, especially in rocky intertidal zones.
Abiotic Factors
- Key abiotic factors include tides, waves, oxygen availability, light levels, density, and sediment types, all influencing organism survival.
Tidal Cycles
- The highest tides occur when the sun and moon align, while the lowest tides occur when they are perpendicular to each other.
Tidal Effects
- Tides expose and submerge coastlines and drive the circulation of bays and estuaries.
Dominant Producers
- Algae are the most common producers found in rocky tide pool areas, playing a crucial role in the ecosystem.
Stressors for Rocky Shore Organisms
- Key stressors include overheating, wave shock, and temperature fluctuations leading to harsh living conditions.
Adaptations to Environmental Stress
- Organisms develop adaptations to minimize overheating and desiccation, such as large body sizes, light coloration, clumping behavior, and retreats to lower areas.
Wave Shock Adaptations
- Organisms exhibit flattened or compressed body shapes and strong adhesion to rocks to withstand wave forces.
Tide Pool Dynamics
- Tide pools can experience rapid changes in oxygen levels, salinity, temperature, and pH when tides return, challenging the organisms within.
Tide Pool Definition
- Tide pools are bodies of water that remain on reefs or beaches after tides recede, creating unique microhabitats.
Tide Pool Organisms
- Common organisms include algae, starfish, anemones, sea urchins, sea cucumbers, and barnacles, each adapted to tide pool conditions.
