Bushwalk Australia

Some interesting research into the impact of the toileting habits of walkers on Tassie Devils, with a potential human-devil parasite transmission.

And here's the original, open access journal paper. Because, when it comes to the media reporting on science, it's always good to see the original source http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0174994

The link is through a paywall. Access by google should bring it up to read (once).
Not that it seems an entirely accurate interpretation, and be good to see a wider framework for poop V wildlife generally.
I suspect, between the omnivores and typical cathole conditions, very little actually stays buried (just observation, no hard data).

I find it interesting that the full article is available on line, but the Mercury hides their misleading version behind a paywall.
The study showed no evidence that bushwalkers transmit any parasites to devils. The only human-type parasite was in a captive devil.

Hence the link to the original research. From that you can draw your own, properly informed conclusions. Which you can't do from the Mercury article. The potential for introduction/transmission of diseases and parasites from walkers like ourselves is an interesting question though and i'd like to see some more research done on this.
