32 <br />reproduction, were abundant in some ponds. They were treated the same <br />as fish when ponds were drained; all were recovered, sub-sarnples were <br />measured, and total biomass recorded. <br />Weights (Wr) and TL of razorback sucker larvae recovered from <br />different treatments were compared using analyses of variance. <br />Non parametric analysis of salamander biomass, and volumes of prey <br />Mmianisms in ponds and fish guts were done with the Mann-Whitney U- <br />test. Strauss' Li was tested for among-treatment differences by <br />regression analysis and comparisons of slopes, and for differences <br />E <br />from zero by a Student's t-test. Loss of samples necessitated <br />combination of data from weeks 2 and 3 for some statistical purposes. <br />General tests for significance among treatments or other oamparisons <br />were by analysis of variance or Student's t-test. Statements of <br />significant difference are at the 0.1 level, unless otherwise noted. <br />Mean values in text are given ± one standard error, where appropriate. <br />Raw data from which figures and tables were compiled are available <br />from Papoulias or from Dexter NFH. All data manipulation and analysis <br />was perforated on an IHK PC cmputer using IotusO, Systat® and <br />Sigmaplot® software.
