AQUATIC BIOMES

1
AQUATIC BIOMES

• -WATER ECOSYSTEMS
• -FRESHWATER, MARINE, ESTUARIES
• -ABIOTIC FACTORS
• -LIGHT INTENSITY
• -OXYGEN LEVELS
• -CARBON DIOXIDE LEVELS
• -ORGANIC AND INORGANIC NUTRIENTS

2
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

3
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

4
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

5
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.

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

• 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

14
NERITIC ZONE

• EXTENDS FROM LOW TIDE LINE TO EDGE OF OPEN SEA
• SEAWEED ABUNDANT HERE, IN PHOTIC ZONE
• KELP FORESTS OF CALIFORNIA

15
NERITIC ZONE CONT.

• MOST OF OCEAN LIFE EXISTS HERE
• MANY SPECIES REPRODUCE HERE
• SUBJECT TO POLLUTION

16
OPEN SEA ZONE

• PHTOPLANKTON 80-90 OF EARTHS PHOTOZYNTHESIS
• BASE OF OCEAN FOOD WEB
• MANY FISH (PELAGIC), MAMMALS (WHALES, DOLPHINS),
  SEA BIRDS
• NUTRIENTS SCARCE
• LIMITS NUMBER OF ANIMALS THERE

18
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

• 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
