Suppose we conduct a study on a rodent species over an area of 120 ha (1 ha = 10,000 m2). It is found that rodents live only in scattered areas represent a quarter of the area of the region. It captures a first sample of 200 individuals, there brand and they are released. Later, capture a second sample of 200 individuals. It is then found that 20% of the animals of the first sample were recaptured. (Answer the following questions by showing your calculations.)
to. Using these data, estimates the size of the total population.
b. What is the density of the population of rodents (in per hectare)?
