Physical Non-Contact Communication between Microscopic Aquatic Species: Novel Experimental Evidences for an Interspecies Information Exchange

Table 1

Listed are the mean values and standard errors () of the absolute population size of Paramecium caudatum at the end of the exposure to Euglena viridis or its absence (yes/no). The separation between the species was conducted with cuvettes made of glass (G) or quartz (Q).

Exposure to Euglena	Material	Mean ± standard error
Yes	G	192.1 ± 4.2
Yes	Q	202.6 ± 5.1
No	G	215.7 ± 5.2
No	Q	213.1 ± 4.8
