鳄鱼天生就是很难研究的动物。然而，对野生动物的研究对于制定可靠的长期管理是必不可少的。在这里，我们描述了通过使用档案标签(数据记录器)以及通过卫星、无线电和声学遥测来获取和监测自由放养鳄鱼的行为和生理变量的方法。具体地说，描述了电子标签的附着或植入，并提供了可以收集的数据类型的示例。我们的研究小组使用了多种方法来监测鳄鱼的运动、潜水活动、体温和心率，包括对澳大利亚淡水鳄鱼(Crocodylus Johnstoni)、河口鳄鱼(Crocodylus Porosus)和凯门鳄(Caiman Atirostris)的研究。每一种做法或方法都提出了独特的挑战和问题，主要是由于鳄鱼物种的身体形态和大小、它们的行为和它们所处的栖息地的差异。
Crocodilians are by their very nature difficult animals to study. However, research on wild animals is essential for the development of reliable long-term management. Here, we describe methods for the acquisition and monitoring of behavioural and physiological variables from free-ranging crocodilians through the use of archival tags (data-loggers) and via satellite, radio and acoustic telemetry. Specifically, the attachment or implantation of electronic tags is described and examples provided of the type of data that can be collected. Our research group has used a combination of approaches to monitor the movements, diving activity, body temperatures and heart rates of crocodilians, including studies on the Australian freshwater crocodile (Crocodylus johnstoni), the estuarine crocodile (Crocodylus porosus) and the caiman (Caiman latirostris). Each approach or method presents unique challenges and problems, chiefly as a consequence of differences in body morphology and size of the crocodilian species, their behaviours and the habitats they occupy.
