| How to study populations of wild mammals? | |
| 2015 Full Book | |
When I was studying biology at the National University of La Plata in the late 1980s, a proverbial final exam question in Nature Protection and Conservation used to be how many jaguars there are in Iguaz£ National Park. It had a precise answer, which I don't remember, but I was intrigued as to how the professor had arrived at a number, as at the time this was unknown. There was a study on the mammals of Iguaz£ National Park by Jorge Crespo of the Bernardino Rivadavia Argentine Museum of Natural Sciences, which described general aspects of the ecology and behaviour of the mammals in that protected area, but no research had been done on the jaguar populations in the region and there was a lack of informed estimates on the abundance or population density of species that, like this one, are solitary, rare, mostly nocturnal, elusive and live in environments with low visibility. |
