To let contrasting that have before education, we including used nonspatial simply take-recapture methods to guess adult jaguar thickness (look for Appendix B having steps and results).
Estimating cub density and you can society framework
We estimated densities separately for males, reproductive women, and you may nonreproductive people. I attempted to match activities right to findings out of cubs, but their simple grab records didn’t bring adequate data to own an optimum possibilities study. So you’re able to guess cub thickness, we multiplied the newest reproductive ladies thickness from our better model by the imply level of cubs each reproductive females. This type of estimates desired computation out of complete jaguar occurrence and population structure for males, nonreproductive ladies, reproductive women, and you can cubs.
Efficiency
Our very own full testing energy are twelve,302 cam pitfall-evening. I obtained 1465 captures, as well as 1369 that have recognizable anyone (Dining table 1). In total, i known 42 jaguars, and fourteen males, fourteen adult lady, and you may 14 cubs. Of one’s 14 photographed mature people, 7 have been earnestly recreating and you can shoot that have cubs (Images D1, D2). Although we inserted equivalent numbers of people, female, and you may cubs on investigation town, the brand new simply take frequency of any classification differed: 58% away from identified photos had been those of males (798 grabs), 33% out of recognizable captures had been the ones from women (452), and just 9% have been those of cubs (119).
