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

  6. VERNAL POOL

  7. VERNAL POOL INDICATOR SPECIES(OBLIGATE SPECIES) MARBLED SALAMANDER BLUE SPOTTED SALAMANDER SPOTTED SALAMANDER FAIRY SHRIMP JEFFERSON SALAMANDER FINGERNAIL CLAM

  8. WOOD FROGS

  9. MARINE BIOMES • -COVER MOST OF EARTH • SUNLIGHT TO ABOUT 200 METERS MAXIMUM • PHOTIC ZONE • PHOTOSYNTHESIS TAKES PLACE HERE • WHERE PHYTOPLANKTON AND ALGAE GROW

  10. PHYTOPLANKTON

  11. 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

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

  13. NERITIC ZONE CONT. • MOST OF OCEAN LIFE EXISTS HERE • MANY SPECIES REPRODUCE HERE • SUBJECT TO POLLUTION

  14. 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

  15. 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

  16. 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
