Top predator ecology and conservation: Lesson from jaguars in southeastern Mexico

Our research is the most comprehensive study of jaguar behavior ecology in Mexico. By analyzing and describing the movements and use of the space, as well as the interactions among individual jaguars, we can better understand their behavioral differences, habitat use, and home range. This type of information is critical for the development and implementation of effective and appropriate conservation strategies. We identified home range size for 14 jaguars in a 13‐year period and described the interspecific relations and use of space by the percentages of overlap of the territories between individuals. Collectively, the average home range size was larger than 200 km 2 , ranging from 48 to 633 km 2 and averaging 296 km 2 for males varied and 37–435 km 2 , with an average of 148 km 2 , for females. However, home range sizes did not differ significantly among males or females. Male territory overlapped about 3.3% on average (range 2.5–15.5%), suggesting that most of the time males avoid each other. Average overlap of female territory was 12%, ranging from 7 to 100%. Males share an average of 18% (range 2–56%) of its territory and with up to five females, suggesting that a given male may be related to all of them at certain periods of time. There were no seasonal changes (dry and rainy seasons) in home range sizes for both male and females. Our research is an important contribution to the ecological information essential for landscape‐level conservation plans for the protection of the jaguars and the biological diversity of the wider Yucatan Peninsula in which they inhabit.
