Sampling Methods Early, mid, and late winter samples Paired with brown trout diets In each sample event: 5 Hess samples 10 minute dipnet sample 10 minutes pupal exuviae collection
Sample Analyses Simpson’s Index with jack-knifing Measure of population diversity (D) Range from 0 < D < 1 • 0 represents no diversity • 1 represents infinite diversity Whittaker’s Percentage Similarity Measure of within-reach heterogeneity Range from 0 to 1 • 0 represents complete heterogeneity • 1 represents complete homogeneity
