Monitoring animal population size, structure, and trend is an
essential part of wildlife biology. However, such monitoring poses
serious challenges when the animals of interest are difficult to detect
because they are rare or elusive, live in concealing environments,
or are sensitive to disturbance. Fortunately, non-invasive
DNA-based methods have been developed to estimate population
size and other parameters and have the advantage that genetic
samples (e.g. hairs or feces) can be collected relatively easily without
the need to see or disturb the animals
