Description

Environmental factors play a large role in determining what species are capable of living and reproducing successfully in an ecosystem. For aquatic ecosystems - stream temperature, altitude, slope, land use, mine drainage and oil well drainage are some of the most restrictive factors that aquatic organisms need to adjust to. Two local trout species, brook trout (Salvelinus fontinalus) and brown trout (Salmo trutta), were looked at in this study to determine and compare thresholds for each abiotic factor stated above. Using data gathered from local, state, and international agencies, averages for each environmental factor were compared between streams that contained neither trout species, only brook trout, only brown trout, and both trout species. Brook trout were significantly more common in cooler, higher, and less human-influenced streams, while brown trout showed the opposite. There was not enough data to find significant differences due to coal mine nor oil well impacted streams.
