Abstract

Animal monitoring research involving mark-recapture techniques increasingly requires non-invasive methods of individual identification. The photographic identification method (PIM) is an excellent tool for this purpose and has been applied successfully to many taxa. However, the utility of PIM is a function of species-specific features that are judged suitable for a given target-species. Herein, the suitability of inguinal color patterns for photo identification of individuals of Pithecopus gonzagai are evaluated by comparing two widely used computer-assisted photographic matching programs (I³S and Wild.ID). Both programs accurately identified more than 70% of individuals in the top 20 potential matching photographs. Wild.ID was slightly better than I³S in matching efficiency and has a faster processing time. Thus, PIM is useful to identify individual P. gonzagai; however, before implementing the technique in animal-monitoring studies of other taxa, one must evaluate the suitability PIM for the target species and calibrate the relative efficiency of the software programs in identifying individuals.

巴西东北部贡萨皮蝗腹股沟颜色图案的照片识别效率

涉及标记再捕获技术的动物监测研究越来越需要非侵入性的个体识别方法。摄影识别方法(PIM)是实现这一目标的一个很好的工具，并已成功地应用于许多分类群。然而，PIM的效用是物种特异性特征的函数，这些特征被判断为适合给定的目标物种。通过比较I³S和Wild.ID两种常用的计算机辅助照片匹配程序，评价了冈萨加皮猿猴腹股沟颜色图案在个体照片识别中的适用性。这两个程序都能准确识别出前20张潜在匹配照片中70%以上的个体。野外。ID在匹配效率上略优于I³S，处理时间也更快。因此，PIM可以有效地识别黄颡鱼个体;然而，在将该技术应用于其他分类群的动物监测研究之前，必须评估PIM对目标物种的适用性，并校准软件程序在识别个体方面的相对效率。
