jaguar's position from horseback, trucks, planes, and on foot will give us the
answers to some of our questions.
So far, we have trapped eight jaguars and four pumas, giving them names that, for Mexico, are exotic -- such as Shoe, Mitcha, Ron, and Tony. We have already learned that jaguars in Calakmul are mainly nocturnal, resting most of the day in the shade of a tree or a cave. Their main prey are peccaries and temazate deer, although they do feed occasionally on other mammals such as coatíes, armadillos, and tepezcuincles. We also know that the jaguar requires from 30 to 59 square kilometers to survive, truly a large expanse of land. In Belize, Venezuela, and Brazil, other researchers have documented a range between 15 and 72 square kilometers. Males need twice as much -- or more territory as females.Because the areas partially overlap, the density of jaguar in Calakmul is one every 15 to 30 square kilometers. This makes for a total population of from between 241 and 482 jaguars in the whole reserve. One direct implication of this information is that the reserve, despite its enormity, is barely sufficient to maintain a viable jaguar population. An appropriate strategy for long-term conservation of the species in the area, then, would mean that it be protected against illegal hunting and that its habitat be protected, both inside and outside the reserves. This means that the jungle areas outside the reserve
