I am back with another odd question. I am studying small mammals and have to collect faeces from them on the field. Problem is that, for some frugivorous species with high metabolism, food is processed quickly through the digestive tract resulting in faeces visually looking a lot like crushed (old) fruits. So my question is: can anybody come up with a simple protocol (ideally, usable on the field) to check whether a sample is really a faeces? Or, in biological terms, do you have an idea what could be present/absent and allow to discriminate such samples?
Thanks a lot in advance for your help.
P.S.: I was not sure which section of the forum was the most appropriate. Sorry if my choice was inappropriate.
