Long distance calls: Negligible information loss of little auk social vocalisations due to high frequency propagation losses
Table 3
Results of the permuted discriminant function analysis for classic calls attenuated to mimic signal structure at distances from 1 to 1000 m (552 calls of 11 individuals per distance), as well as for all distances pooled together (5520 calls of 11 individuals), using the principal components of eigenvalues > 1.
Calls could be reliably classified to individuals above chance levels independently of the attenuation.
