Ecology:
Theory and Applications Gaytha A. Langlois,
Ph.D. Site
Map Ecology
- Test Review - Lab Exam Techniques Compound Microscope
Dissecting (stereo)
microscope
Use of PASCO kits
to test pH and Temperature
Water Quality Tests
(dissolved oxygen; salinity, nitrates, phosphates)
Photosynthetic pigment
extraction & separation (chromatography)
Soil Measurements
(% moisture; grain size; soil organisms)
How to measure photosynthesis
(Elodea) & respiration (Gammarus)
Assessing tree growth
in a wetlands
Organisms Diatoms (e.g., Fragillaria,
Tabellaria, Pinnularia)
Green algae (e.g.,
Closterium,Spirogyra)
Protozoa (e.g.,Amoeba,
Vorticella, Paramecium, Stylonychia) Planaria
Gammarus sp.
Daphnia Nematode worms
Rotifer
Aiptasia (sea
anemone)
Tardigrades
Data Results of Aiptasia
population growth experiment
Variation in student
heights
Response of planaria
to light exposure
Response of gammarids
to neutral red and methyl blue dyes
Fish respiration &
temperature stress
Structure of an aquatic
food web
Photosynthesis &
Respiration results in Elodea
General Information How to read a graph
How to organize a
lab report
Challenges for animals
in terrestrial versus aquatic environments
General characteristics
of a freshwater wetland
What do the Aiptasia
eat (in our aquaria)?
Why is the level of
nitrates or phosphates important in pond water?
How long does it take
for frog tadpoles to hatch? (e.g., leopard frogs and green frogs)
How are wetland soils
different from upland soils?
Importance of ripraps
to control erosion
