1. Intermediate metrics of translocation success are useful for long-lived, slow to mature species where survival and reproduction happen over decades.
2. With fewer than 150 individuals in the wild, the Critically Endangered Philippine crocodile (Crocodylus mindorensis) is one of the most threatened species on Earth. This study presents the first analysis of diet and body condition of wild Philippine crocodiles and headstarted (i.e. captive-reared) individuals released into the wild over the last decade, and uses these results to show how diet and body condition can be pertinent intermediate metrics of translocation success.
3. Analyses of stomach contents revealed 17 different aquatic and terrestrial invertebrate and vertebrate prey species. Interestingly, 70% of Philippine crocodiles showed snails to be the predominent prey type, followed by fish (36.7%), birds (33.3%) and reptiles (33.3%). More than 50% of crocodiles consumed the invasive golden apple snail, a leading agricultural pest. Regardless of crocodile history (wild vs. headstarted) or size class (juvenile vs. adult), no evidence was found for dietary differences in percentage occurrence, percentage composition or prey diversity.
4. Body condition was significantly higher in wild compared with headstarted individuals when analysed together in a pooled group, although neither group differed significantly from the standardized expectation, and headstarted individuals were not significantly different when body condition was derived independently for the two groups.
5. This study provides a working example of how assessing the convergence of diet and body condition between translocated and wild individuals can provide complementary monitoring parameters to demonstrate post-release establishment of translocated crocodylians. The congruent dietary composition and comparable body condition observed in this study suggest that headstarted crocodiles adapt well following release.
6. Crocodylus mindorensis survives in an agricultural landscape and is likely to play an ecologically important role by exploiting invasive species, reinforcing the importance of this species to local communities.

使用饮食和身体状况评估作为极危菲律宾鳄鱼 (Crocodylus mindorensis) 易位成功的中间指标

1. 易位成功的中间指标对于存活和繁殖持续数十年的长寿、缓慢到成熟的物种很有用。
2. 极度濒危的菲律宾鳄鱼 ( Crocodylus mindorensis )在野外的数量不到 150 只，是地球上最受威胁的物种之一。本研究首次分析了过去十年中放归野外的菲律宾野生鳄鱼和先发制人（即圈养饲养）个体的饮食和身体状况，并使用这些结果表明饮食和身体状况如何成为相关的中间指标。转位成功。
3. 对胃内容物的分析揭示了 17 种不同的水生和陆生无脊椎动物和脊椎动物猎物。有趣的是，70% 的菲律宾鳄鱼显示蜗牛是主要的猎物类型，其次是鱼 (36.7%)、鸟类 (33.3%) 和爬行动物 (33.3%)。超过 50% 的鳄鱼吃掉了入侵的金苹果螺，这是一种主要的农业害虫。无论鳄鱼的历史（野生与自暴自弃）或大小等级（幼年与成年），都没有证据表明饮食在出现百分比、组成百分比或猎物多样性方面存在差异。
4. 在合并组中一起分析时，野生动物的身体状况显着高于头脑清醒的个体，尽管两组都与标准化预期有显着差异，而且当两个群体的身体状况独立得出时，头脑清醒的个体没有显着差异。
5. 这项研究提供了一个工作示例，说明如何评估易地和野生个体之间饮食和身体状况的趋同性，可以提供补充监测参数，以证明易地鳄鱼的释放后建立。在这项研究中观察到的一致的饮食成分和类似的身体状况表明，先发制人的鳄鱼在释放后适应良好。
6. Crocodylus mindorensis在农业景观中生存，并可能通过开发入侵物种发挥重要的生态作用，加强该物种对当地社区的重要性。
