Identification of animal tissue in support of WIIS
... Why do you need to identify tissues? Entire animals are normally easy to identify, although identification of juveniles can sometimes be problematic. However, often when we are investigating wildlife crime the whole animal is not available. This may be due to predation or decomposition of carcasses ...
