Canine Conversations

In this episode of K9 Conservationists, Kayla speaks with Misa Winters and Tara Wilson about laboratory analysis of scat after field collection. Science Highlight: Duration of urination does not change with body size What can we learn from our scat samples? Genetic analysis (what species, what individual, what did it eat, sex typing) Morphological diet analysis (fur, bones, teeth, plants, insects) Microbiome (bacteria and immune system interaction) Parasites, pathogen analysis (bacteria and viral disease) Hormonal analysis (stress, pregnancy, nutrition, relative age) Age (isotope data) Hormones in particular are great from scat because it is more representative of an animal over time, versus a blood sample which is a smaller snapshot in time and could be skewed by the stress of capturing or darting an animal. What questions from samples are harder/easier to answer? Easier: Species ID from mitochondrial DNA (if you have good reference data) Prey analysis (if you have a targeted strategy - e.g. it’s
