    1. Algae Investigation Olivia Buvala Wildlands Semester Evaluation

    3. Project Mission Informative Algae Basic Knowledge My Experiments Pollution Indicators

    4. Algae Benefits: Base of the aquatic food chain Useful indicators of pollution Help remove excess nutrients Produce oxygen Constitute the raw material to make agar, iodine, and various food products. Provide spawning habitat for fish

    5. Algae Q. What do the mother’s of blue-green algae hope for? A. That their daughter cells will grow up and marry pond scum

    6. Plant vs. Protist Termed Algae In brief- Simple one-celled Group in colonies Also form organisms with many cells And collaborating together as simple tissues.

    7. Reproduction Spore (May be motile or non-motile) Simple sex Where algae act gametes But can also operate with complex egg and sperm cells

    8. Helpful Hints:Motile Flagellated UnicellSelf Propelled-with a whip-singular cell

    9. Algal Reproduction Q. Why did the algae fail math? A. He divided when mutliplying

    10. Energy Heterotrophic- Heteron=(an)other Trophe=nutrition Synthesizing required organic materials from inorganic sources Photosynthetic- Sunlight to synthesize carbohydrates from carbon dioxide and water

    11. Non-aquatic Habitats Animals- Turtles, snails, rotifers, worms, crustacea, alligators, three-toed sloths, sponges, etc. Soil- Composition varies Terrestrial plants- Via lichenised fungi, shady tree sides, penetrate leaves (rainforests), tree hollows, pitcher plants Snow Rocks- Internal and external

    12. Algae Q. What is the most common form of algae transportation? A. A nitrogen-cycle

    13. Aquatic Habitats Aquatic Plants- Internal and external Lagoons & Billabongs- Rich in desmids Bogs, marshes, swamps- Also rich in desmids(ex. In Sphagnum Hot Springs- Blue-green algae dominate Lakes- All have planktonic algae (free floating or swimming) and periphytic (surface attached)

    14. Aquatic Habitats (cont’) Reservoirs- Provide ideal protected habitat for microalgae Rivers, Streams, Creeks- Wide distribution Mud & Sand- Many species Ponds, Puddles, Roadside Ditches, & Rock Pools- Air transported algae

    15. Periphyton Surface Attached Algae Food source (invertebrates, fish) Water quality indicator Represents physiological and community-level changes

    16. Algae Q. What kind of algae most often joins the military? A. Fighter-planktons

    17. Pollution Indicators:Why are algae such good indicators? Naturally high population Rapid response time Identification to a species level Ease of sampling Tolerance or sensitivity to specific environmental conditions known

    18. Pollution Indicators:Rapid Bioassessment Objectives Assessment of: Biomass Species Composition Biological Condition of Periphyton Assemblages

    19. Details, details, details:Epiphytic and Benthic Epiphytic one organism living within or upon another without causing harm.

    20. Pollution Indicators:Phosphorus Change in algal communities Enriched conditions increase or decrease, depends on epiphytic/benthic, pH, water regime, original state… Florida regulations- less than 1mg/L Species usually affected:

    21. Pollution Indicators:Phosphorus

    22. My Protocol Mark Point on GPS Label sample bag with date, stream, site, sample # Select a cobble size substrate Lift cobble from bed into submerged collecting tray Pour all but a small amount of water out of the collection tray Remove algae from substrate using nylon brush by brushing down into the water in the container for 3 minutes until all algae is visibly removed Rinse substrate, brush, and fingers with 50-100 mL into container Rinse container and pour sample into sample bag Check label Add sample to cooler

    23. My Data Motic Images Data Collection Tool Digital Microscope

    24. My Images

    25. Sampling Sampling Area Eau Claire River Multiple samples Bends, straights, rougher waters Deinhammer Creek Multiple samples Mouth, bends, straights Varying substrates Beaver Creek Pine Creek

    26. Terms to Know:Substrates Substrates: The surface upon which algae attaches its self. Rocks Wood (bark, submerged trees, logs…) Man-made structures (pipes, bridges, boards…) Anywhere

    27. Data Collection

    28. The Final Joke Q. What couldn’t the algae keep a steady relationship? A. He wasn’t really a fun-gi
