Our meta-analysis of the diet of the Eurasian otter is now published in the April issue of Mammal Review.
We showed that the plasticity of otter feeding behaviour might be explained by the various habitats occupied by otters. Habitat differences reflected in otters’ diets might have importance for the maintenance and conservation of local populations of this species.
The other important point is that the high diversity of methods used by researchers to report the results of dietary studies precludes full comparisons and synthesis. This demonstrates the importance of unification of reporting. Moreover, the conclusions reached by the authors of any particular study might be highly dependent on the method they applied.
