Estimating jaguar (Panthera onca) density in a preserved coastal area of French Guiana
Résumé
Knowledge of the jaguar population is needed in French Guiana that faces an increase of human-jaguar conflicts. We carried out a camera trap survey to assess jaguar local density and home range size in a preserved coastal area of French Guiana. We ran spatially explicit capture recapture (SECR) models. In our model, the scale parameter σ, that is linked to the home range size, was larger for males (σ = 3.87 ± 0.59 SE km) than for females (σ = 2.33 ± 0.30 SE km). The assessed jaguar density was 3.22 ± 0.87 SE ind. 100 km−2, which should be considered as an optimal density in a French Guiana coastal area.
