Detection of fish DNA in faeces of trawling Myotis species

Fish remains are difficult to detect in faecal pellets of bat species; thus, piscivory may not always be reliably detected by morphological identification of prey remains. But with the help of fish DNA in the faeces and DNA barcoding, fish was revealed a part of the diet European bat species also in Germany. The findings of this study improve our understanding of ecological relation around water bodies.
