Study Notes
Mangrove Fauna
- Mangroves protect coasts and nurture life.
- Mangrove fauna refers to animal life in mangrove ecosystems.
- Mangroves are tropical and subtropical coastal forests with salt-tolerant trees/shrubs.
- These forests stabilize coastlines, reduce erosion, and provide habitats for marine/terrestrial species.
- Mangrove fauna encompasses various species including fish, birds, crustaceans, mollusks, and mammals.
What is Mangrove Fauna?
- Fauna is the animal life found in a particular region (similar to flora for plants).
- Mangrove fauna specifically refers to animal species associated with mangrove ecosystems.
- Fish use mangroves as breeding and nursery grounds.
- Birds use mangroves for nesting and feeding.
Fauna of Mangrove Ecosystems: Fish
- Mangrove Red Snapper ( Lutjanus argentimaculatus)
- Popular fish species in mangrove habitats.
- Striking red colour and size.
- Tarpon ( Megalops cyprinoides)
- Large fish known for jumping.
- Often found in mangrove areas.
- Mudskipper ( Periophthalmus spp.)
- Unique fish, also moves on land.
- Uses pectoral fins to "walk" and breathe through skin/mouth.
Fauna of Mangrove Ecosystems: Birds
- Pacific Reef Heron ( Egretta sacra)
- Wading bird that hunts in shallow waters.
- Collared Kingfisher ( Todiramphus chloris)
- Vibrant colors and impressive hunting skills.
- Often seen near water.
- Black-crowned Night Heron ( Nycticorax nycticorax)
- Nocturnal bird feeding on small fish and invertebrates.
- Common in mangrove areas.
Fauna of Mangrove Ecosystems: Crustaceans & Mollusks
- Blue Swimming Crab ( Portunus pelagicus)
- Known for its sweet meat, valuable for the economy.
- Mangrove Whelk ( Terebralia palustris)
- Large snail prevalent in mangrove areas.
- Mud Crab ( Scylla serrata)
- Large crab, valued for its meat.
- Giant Clam ( Tridacna gigas)
- One of the largest mollusks often found in mangroves.
Fauna of Mangrove Ecosystems: Mammals
- Philippine Long-tailed Macaque ( Macaca fascicularis)
- Primate that may venture into mangrove areas.
- Dugong ( Dugong dugon)
- Gentle sea mammal grazing on mangrove vegetation.
Mangrove Plant and Fauna Interactions
- Mangrove root systems provide habitat for fish/invertebrates supporting birds.
- Mangrove leaves are a nutrient source for algae/invertebrates creating a productive food web.
- Microorganisms cycle nutrients (important in maintaining health and productivity).
- Fallen leaves decompose, releasing nutrients for other organisms.
- This creates a balanced, interconnected food web.
How do Mangrove Vegetation Adapt to Salt Water?
- High salinity harms plants by drawing water from them.
- Mangrove leaves have a waxy cuticle preventing water loss.
- Salt exclusion at leaves helps control salt content in plants.
How do Mangrove Vegetation Adapt to High Sedimentation?
- Buttress roots (thickened roots) stabilize mangroves in soft, unstable soil.
- Stilt roots grow from the base of the tree into the substrate.
- Pneumatophores (breathing roots) grow upward from the sediment and absorb air.
Mangrove Adaptation to Reproduction
- Vivipary (some mangroves reproduce while still attached to plant).
- Floating propagules (seedlings) dispersal to new environments.
- Pollination method varies by species (wind, bats, birds, insects).
Human Impacts on Mangroves
- Deforestation & Land Conversion (cleared for agriculture, urbanization, aquaculture leading to loss).
- Pollution (industrial/agricultural pollutants affecting water quality and mangrove health).
- Climate Change (sea levels rise, storm intensity affecting mangroves sustainability).
- Overexploitation (overharvesting for timber, fuel, etc).
