Algae Investigation Olivia Buvala Wildlands Semester Evaluation
Contents • Mission • About Algae • Periphyton • Algae as Indicators
Project Mission Informative Algae Basic Knowledge My Experiments Pollution Indicators
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
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
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.
Reproduction Spore (May be motile or non-motile) Simple sex Where algae act gametes But can also operate with complex egg and sperm cells
Helpful Hints:Motile Flagellated UnicellSelf Propelled-with a whip-singular cell
Algal Reproduction Q. Why did the algae fail math? A. He divided when mutliplying
Energy Heterotrophic- Heteron=(an)other Trophe=nutrition Synthesizing required organic materials from inorganic sources Photosynthetic- Sunlight to synthesize carbohydrates from carbon dioxide and water
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
Algae Q. What is the most common form of algae transportation? A. A nitrogen-cycle
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)
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
Periphyton Surface Attached Algae Food source (invertebrates, fish) Water quality indicator Represents physiological and community-level changes
Algae Q. What kind of algae most often joins the military? A. Fighter-planktons
EPA 1 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
EPA 2 Pollution Indicators:Rapid Bioassessment Objectives Assessment of: Biomass Species Composition Biological Condition of Periphyton Assemblages
Details, details, details:Epiphytic and Benthic Epiphytic one organism living within or upon another without causing harm. Benthic Living in or on the bottom of a body of water
EPA 1 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:
EPA 1 Pollution Indicators:Phosphorus Pandorina Dinobryon Scenedesmus Schroederia Anabaena Oscillatoria Staurastrum Aphanzinomenon Pediastrum Cosmarium Microcystis Closterium Microsterias
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
My Data • Motic Images • Data Collection Tool • Digital Microscope
My Images Hydrodictyon Chlorella Cosmarium Microspora
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 Proper Sampling Apparel
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
EPA 2 Data Collection
The Final Joke Q. What couldn’t the algae keep a steady relationship? A. He wasn’t really a fun-gi
