The aim was to determine which faecal DNA field preservation method best enhances PCR amplification success. Samples stored in ethanol showed a significantly higher amplification success of microsat ellite loci than samples stored in the other two media. In contrast, amplification success of a mitochondrial locus was similar among the samples stored in the three types of media. We reviewed twelve previous studies that employed different media for the storage of faeces, although patterns of success were not fully consistent among different media, ethanol storage was scored high est in the majority of these tests展开更多
