Pygospio elegans size distributions - The 5th setiger widths of P. elegans for the weed and non-weed plots after 4 weeks and 20 weeks are given in Figures 5.5(i) and (ii) respectively. The results of the X 2 goodness of fit and Kolmogorov-Smimov tests are given in Table 5.2. 5th setiger X2 goodness of fit K-S width (mm) 0.30 0.33-37 0.40-43 0.47-50 0.53 p value p value 4 Weeks 77.1% 1.2% 7.4% 9.0% 5.2%
After 20 weeks, there was no significant difference between the P. elegans size- frequencies in the weed and non-weed plots although this was probably due to the low abundances in the non-weed plots preventing a definite size distribution being ascertained. c.) 80 — (i) 4 Weeks 70 — 60 — 50 — 40 — • 30 — L) 4.9 LL. 20 — 10 — 0 1 1 1I 120 — 100 — 80 — 60 — 40 — 20 — 0 r-- o en r-- N 6 6 6 -11 N --, 6 1 0 en r- N N N 6 6 6 1 1- r- o • •zr. o I I 1 1 1 r- o . o 1 Fifth setiger width (mm) (ii) 20 Weeks en • Non-weed plots n = 297 El Weed plots n= 609 • Non-weed plots n = 55 El Weed plots n = 940 1 I Elm o en 6 en en 6 r- en 6 • 1111 o en
