Appendix A. A table presenting summary data for Gyrinophilus porphyriticus individuals captured during surveys of Merrill Brook, a first-order stream in northern New Hampshire, in June, July, and August of 1999–2004.

TABLE A1.Summary data for Gyrinophilus porphyriticus individuals captured during surveys of Merrill Brook, a first-order stream in northern New Hampshire, in June, July, and August of 1999–2004. Movement data are from individuals that were marked and recaptured in the same year (“Recaptures”). Body condition and dispersion index values are from individuals that were marked and not recaptured in each year (“New captures”). Standard errors of kurtosis estimates were calculated using methods in Cramer and Howitt (2004).
