Table 1 Biovolume of Food vs Thoracic Beats in D. magna One Way Analysis of Variance Thursday, February 02, 2006, 4:26:10 PM Group Name N Missing Mean Std Dev SEM Mean TB High Micro 4 0 190.500 39.233 19.617 Mean TB Low Micro 4 0 220.200 68.091 34.045 Mean TB High Nano 4 0 147.600 11.758 5.879 Mean TB Low Nano 4 0 198.300 19.751 9.876 The differences in the mean values among the treatment groups are not great enough to exclude the possibility that the difference is due to random sampling variability; there is not a statistically significant difference (P = 0.140). Though there is no significant difference between the Biovolume level of food and the number of thoracic beats in D. magna, there was a trend observed where the Daphnia performed a greater number of thoracic beats at the lower concentrations of food. Also, there was a trend where the number of thoracic beats was greater when in concentrations of Nanocloropsys.

One Way Analysis of Variance Tuesday, February 07, 2006, 1:57:21 PM Data source: Nanno & MC Data in zool811 Mic vs TB Normality Test: Failed (P < 0.050) Kruskal-Wallis One Way Analysis of Variance on Ranks Tuesday, February 07, 2006, 1:57:21 PM Data source: Nanno & MC Data in zool811 Mic vs TB Group N Missing Median 25% 75% Micro PAR lo 4 0 1.667 1.167 2.333 Micro PAR hi 4 0 2.333 1.333 3.500 Nanno PAR lo 4 0 1.000 0.667 1.833 Nanno PAR hi 4 0 2.500 1.333 6.167 H = 2.789 with 3 degrees of freedom. (P = 0.425) The differences in the median values among the treatment groups are not great enough to exclude the possibility that the difference is due to random sampling variability; there is not a statistically significant difference (P = 0.425)

  6. Post Abdominal Rejection at Low and High Food Concentrations There is no significance between the post abdominal reflexes (PAR) at the food concentrations tested, however, one allegedly present trend was noted: there were fewer PAR’s in the low concentrated substrates.
