Suggest why it was not appropriate to estimate the number of Jaguars using the capture-recapture technique (2) - Ans .Estimate will be inaccurate because it is a low number. Dangerous for collector. Most studies estimate the population density of Jaguars South American rainforest to be 5 individuals per 100km2. In the 2007 study: • 100 camera traps were set up covering an area of 271 km2. • 28 images of 9 different jaguars were recorded. How well do these results support a populati...
