So that reviews having prior to training, we as well as applied nonspatial just take-recapture approaches to imagine mature jaguar thickness (look for Appendix B for strategies and you will efficiency).
Estimating cub occurrence and you can populace construction
We projected densities on their own for men, reproductive lady, and you can nonreproductive women. I attempted to complement activities right to findings regarding cubs, but their simple capture records did not promote enough studies to have an optimum possibilities data. So you can imagine cub density, we increased the fresh reproductive female density from your top 
design by suggest amount of cubs for every single reproductive females. These estimates allowed computation of complete jaguar density and you may inhabitants build for males, nonreproductive lady, reproductive women, and you can cubs.
Performance
All of our complete testing efforts is actually 12,302 digital camera pitfall-nights. I gotten 1465 captures, together with 1369 with recognizable individuals (Desk step 1). Overall, i identified 42 jaguars, along with fourteen males, 14 adult females, and you will fourteen cubs. Of the 14 photographed adult lady, 7 was indeed positively reproducing and you may shoot having cubs (Photographs D1, D2). Although we entered equal quantities of people, women, and cubs from the study area, the newest need frequency of each and every group differed: 58% of identified photographs was indeed those of men (798 catches), 33% away from identifiable catches was in fact those of female (452), and only 9% was that from cubs (119). Normally, males have been caught 56 moments for every, people 32 times, and you may cubs only 9 minutes. Reproductive women had a bit highest final number of catches than nonreproductive female (257 as opposed to 195, respectively) and better average quantity of captures each private (38 instead of twenty eight). Reproductive females were more frequently grabbed alone (109 minutes) than just accompanied by cubs (69 grabs) throughout identified young ones dependency. However, cubs was indeed submitted more frequently with regards to parents (83 private catches) than simply alone (thirty six grabs).
Occurrence prices out of mature jaguars
Of the 32 models analyzed with the secr package with sex/reproductive status and sessions as covariates, those which did not allow density to vary across sessions obtained the lowest AICc values. In contrast, models assuming density variation across sessions received less support (Tables 2, C1). The top secr model for adult jaguars included an effect of sex/female reproductive status on D, ? 0, and ? and between session variation in ? 0. All three parameters differed significantly between sex/reproductive status groups (Table 3). Baseline detection probability was lowest for reproductive females (0.04 on average), whereas nonreproductive females had the greatest baseline detectability (0.13 on average) and males intermediate (0.08 on average) to the two female reproductive classes. Males had the largest values of estimated movement distribution (? = 2.97 ± 0.09 km), while reproductive and nonreproductive females obtained smaller ? values (2.04 ± 0.11 and 2.32 ± 0.19 km, respectively). Estimated densities were higher for reproductive females and males (1.97 ± 0.33 and 1.62 ± 0.22 individuals/ 100 km 2 , respectively) than for nonreproductive females (0.85 ± 0.19 individuals/100 km 2 ). In total, the best model estimated 4.44 ± 1.16 adult jaguars/100 km 2 (Table 3).
Cub thickness and jaguar inhabitants construction
Of findings of your 7 reproductive female which have youngsters from inside the analysis months, i projected step 1.64 cubs for every single reproductive females an average of. As well, one cub try submitted alone using one event along with a not known mother. I omitted that it solitary observance regarding further study. On the basis of reproductive lady occurrence about greatest model, we estimated 3.23 cubs/100 km 2 regarding research area. Hence, i estimated an entire density out of eight.67 jaguars/a hundred km dos . Jaguar population structure try 21% men, 11% nonreproductive lady, 26% reproductive females, and you will 42% cubs (Desk step three).
