Table 2.
Relationship between light and activity
species | r2 | p | type | trend |
---|---|---|---|---|
D. polychroa | 0.005 | 0.87 | lin | - |
D. tigrina | 0.653 | <0.01 | log | - |
P. tenuis | 0.0003 | 0.97 | lin | + |
Correlations between diel light irradiance and planarian activity, using the values reported in Figure 1 (n = 8 and df = 6 for each correlation). Best fitting correlations are reported for each species; lin = linear and log = logarithmic relationships; positive and negative trends are reported as "+" and "-", respectively.
