AQUATIC BIOMES

-WATER ECOSYSTEMS

-FRESHWATER, MARINE, ESTUARIES

-ABIOTIC FACTORS:

-LIGHT INTENSITY

-OXYGEN LEVELS

-CARBON DIOXIDE LEVELS

-ORGANIC AND INORGANIC NUTRIENTS


Freshwater biomes
FRESHWATER BIOMES

  • RIVERS, LAKES, STREAMS, PONDS, VERNAL POOLS

    • SUPPLY DRINKING WATER

    • MANY BECOMING POLLUTED

    • BECOMING SCARCE IN MANY AREAS

    • SOURCE OF FOOD

      • FLOATING PLANTS/ANIMALS (PLANKTON) PROVIDE FOOD FOR FISH, AMPHIBIANS


Vernal pools
VERNAL POOLS

  • TEMPORARY POOLS (2000 IN MASS.)

  • FORM IN SPRING FROM SNOW MELT/RUNOFF

  • SUPPORT SPECIES FOUND IN NO OTHER ECOSYSTEMS

  • OBLIGATE SPECIES REPRODUCE ONLY IN TIDE POOLS

  • DESIGNATED VERNAL POOLS ARE PROTECTED

  • ANYONE CAN HAVE A VERNAL POOL CERTIFIED


Vernal pool characteristics
VERNAL POOL CHARACTERISTICS

  • MUST DRY UP IN SUMMER

  • MUST HAVE NO INLET OR OUTLET

  • MUST SUPPORT AT LEAST ONE OBLIGATE SPECIES

  • OBLIGATE SPECIES INCLUDE:

    • FAIRY SHRIMP

    • FINGERNAIL CLAMS

    • MOLE SALAMANDERS

      • JEFFERSON

      • SPOTTED

      • MARBLED

      • BLUE SPOTTED


Vernal pool certification
VERNAL POOL CERTIFICATION

  • SIGNED APLICATION

  • DOCUMENT LOCATION (MAP)

  • TAKE PHOTOS OF AREA

  • TAKE PHOTOS OF OBLIGATE SPECIES

  • PROVIDE EVIDENCE OF OBLIGATE SPECIES (NOT THE ORGANISMS THEMSELVES!)

  • CONTACT/SEND INFO TO WILDLIFE DEPT.

  • http://www.vernalpool.org/macert_3.htm

Marine biomes
MARINE BIOMES

  • -COVER MOST OF EARTH

  • SUNLIGHT TO ABOUT 200 METERS MAXIMUM

    • PHOTIC ZONE

    • PHOTOSYNTHESIS TAKES PLACE HERE

      • WHERE PHYTOPLANKTON AND ALGAE GROW



Interdtidal zone
INTERDTIDAL ZONE

  • VERY NARROW AREA NEAR SHORE

  • SUBJECT TO POLLUTION

  • DIFFICULT FOR LIVING THINGS

  • MUST TOLERATE CHANGING CONDITIONS

  • SUBMERGED PART OF DAYM EXPOSED TO AIR PART OF DAY

  • ADAPTATIONS TO SURVIVE POUDING WAVES

    • CLAMS BURROW

    • BARNACLES, SEAWEED ATTACH TO ROCKS

    • SNAILS, URCHINS, SEASTARS CLING TO ROCKS


Neritic zone
NERITIC ZONE

  • EXTENDS FROM LOW TIDE LINE TO EDGE OF OPEN SEA

  • SEAWEED ABUNDANT HERE, IN PHOTIC ZONE

  • KELP FORESTS OF CALIFORNIA


Neritic zone cont
NERITIC ZONE CONT.

  • MOST OF OCEAN LIFE EXISTS HERE

  • MANY SPECIES REPRODUCE HERE

  • SUBJECT TO POLLUTION


Open sea zone
OPEN SEA ZONE

  • PHTOPLANKTON: 80-90% OF EARTH’S PHOTOZYNTHESIS

    • BASE OF OCEAN FOOD WEB

  • MANY FISH (PELAGIC), MAMMALS (WHALES, DOLPHINS), SEA BIRDS

  • NUTRIENTS SCARCE

    • LIMITS NUMBER OF ANIMALS THERE


Deep sea zone
DEEP SEA ZONE

  • AREA OF HIGH PRESSURE

  • TOTAL DARKNESS, COLD TEMPERATURES

  • INHABITED BY MANY STRANGE ORGANISMS

  • FEED ON DETRITUS FROM ABOVE AND ON EACH OTHER

  • ZOOPLANKTON MIGRATE TO SURFACE AT NIGHT TO FEED ON PHYTOPLANKTON

  • MANY BOTTOM DWELLERS


Estuaries
ESTUARIES

  • BOUNDARY BETWEEN FRESH, SALT WATER

  • SALT MARSHES, MANGROVE SWAMPS, LAGOONS, MOUTHS OF RIVERS

  • MIXTURE OF FRESH/SALT WATER

  • SUPPORT VARIETY OF LIFE

  • SHALLOW, SUPPORTS AQUATIC PLANTS

  • MANY FISH, INVERTEBRATES

  • SPAWNING, HATCHING AREAS FOR MANY

  • NESTING AREAS FOR SOME BIRD SPECIES
