students explain how DNA is extracted from Bighorn Sheep scat samples. -
Sample preparation - PCR
Use for DNA Extraction
Instructions for how to use
equipment for DNA extraction. - Vortex - Centrifuge -
Macroinvertebrates - Feeding Groups and Sampling
An overview of benthic
macroinvertebrate sampling in Montana alpine streams.
Fairy shrimp, eubranchipus, inhabit vernal pools and tarns. Discover their means of dispersal and get a glimpse into their life cycle. This is the beginning of a DNA study that will examine their genetic diversity.
Bighorn Sheep Scat Collection
Students demonstrate a method for collecting and cataloging bighorn sheep scat samples to be used for DNA analysis.
Hydrology, Water Chemistry, and LabQuest Use
Students examine the interrelatedness of soil and water pH and measure changes in dissolved oxygen and turbidity in various portions of a stream. A lab for determining soil pH is demonstrated, as is the use of Labquest meters to measure turbidity, pH, and dissolved oxygen.
CWW students demonstrate how to locate transects and monitor their use by deer and elk. Filmed at Calf Creek WMA near Corvallis, MT.
