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 mothers 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 couldnt the algae keep a steady relationship?
A. He wasnt really a fun-gi
