“Conversations with Fireflies” by Lisa Carloye

Handout 4

LBG content of Photuris females, plotted as a function of LBG-I consumed.

2 graphs showing LBG content

Data are presented as concentrations as in the previous Handout 3. In both cases, significant differences were detected [ANOVAs of log (x + 1) transformed data, P<0.0001]. Within a plot, columns not sharing underlining are significantly different (experiment-wide alpha = 0.05).

Questions

  1. What conclusions can you draw based on these data?
  2. In this experiment the scientists fed Photuris spp. different LGB concentrations. Why was this a necessary experiment?
