Using fecal profiles of bile acids to assess habitat use by threatened carnivores in the Maulino forest of central Chile

The distribution and habitat use by carnivores can be assessed by studying their tracks or feces. If these methods are to be used confidently, they should not only unequivocally discriminate among species, but should also render the same patterns of spatial distributions. We assessed the fulfillment...

If these methods are to be used confidently, they should not only unequivocally discriminate among species, but should also render the same patterns of spatial distributions.

description	The distribution and habitat use by carnivores can be assessed by studying their tracks or feces.
