Selection of the best model generalized linear models (GLM) for echolocation click and click train parameters.

The first column shows the ranks, numbered from the smallest Akaike’s Information Criterion (AIC). This table shows models with AICs < 2. The second column shows the explanatory variables for GLMs (vessel = absence/presence of vessel noise, DN = day/night, vessel: DN = interaction between day/night and absence/presence of vessel noise, temp = temperature, flow = synthetic flow velocity, noise level = noise level, site = recording site). Bold text indicates the respective response variable. df: degrees of freedom.
