Figure 9.
Results on occurrence of mayflies in each substrate for pseudo-replicas experiments: (A) results are shown for each pseudo-replica; (B) results of all pseudo-replicas are summed. Replica no. 1 indicate the first time of exposure. NAT = natural substrate; lMP = PET, PP, PS (in equal proportions); MIX = NAT and lMP (50% each). The images (A) and (B) are obtained by the software GraphPad Prism (ver. 8.4.2, https://www.graphpad.com/support/faq/prism-842-release-notes/).
