P Value

What creeks are most similar and why:

Buck and Booth are most similar because there is only a 59.46% chance that the observed difference is by random chance.

Which river is the best match to Buck mountain:

After comparing our 2 sample sights (Rocky upper and Upper lower), we have concluded that rocky upper is more similar to buck mountain than rocky lower.

What parameters are most similar and which differ the most:

Turbidity is the most similar, while temperature is the most different.

Benthic 

Most common species in each season:

  • Water pennies, netspinners, and hellgrammites all appeared most commonly in fall

  • Asian clams and gilled snails were most commonly found in winter.

  • Trueflies, midges, beetles, caddisflies, dragonflies, mayflies, stoneflies, and worms were all most commonly found in spring

  • Spring was the season with the greatest variety of species 

  • May was the month in which the benthic scores were the highest, with mayflies and caddisflies appearing the most.

Most common species at each creek:

  • At Rocky Creek, the Midge was the primary species recorded.

  • At Upper Rocky, the Caddisfly was species recorded the most.

  • At Lower Rocky and Buck Creek, the mayfly was the most recorded species

Benthic scores:

Out of the three locations, lower Rocky received the highest average benthic score of 116, while Buck’s average was 81, and Rocky’s average, the lowest, was 76.

General Conclusions

  • We found 2 live JSM and 2 Stuns in the Meechum’s River upstream of the Barracks Road Bridge

  • We isolated Asian clam DNA, ran a gel indicating the presence of the DNA

  • Each student designed and conducted their own research project related to water quality
