An understanding of cetacean distribution is necessary to gain insights into crucial ecological processes for species conservation management. However, cetacean habitat preference and distribution in the northern Savu Sea, Indonesia are still poorly understood. We use maximum entropy modelling with five environmental predictors to describe habitat preference and distribution of seven cetacean species in the northern Savu Sea. Our study confirms that static predictors are the most important variables in explaining habitat preferences of seven cetacean species in the northern Savu Sea. Seasonally, each cetacean species has a different environmental preference. Globicephala macrorhynchus prefers the open nearshore areas adjacent to deep waters. Stenella attenuata is associated with nearshore habitats and higher productivity areas. Stenella longirostris prefers nearshore habitat during coastal upwelling events. Tursiops truncatus prefers nearshore sheltered habitat. Grampus griseus habitats are highly related to depth and steep gradients around the isobaths of 200-1,000 m. Feresa attenuata are associated with deep waters and cooler sea temperature. Pseudorca crassidens prefers protective bays with productive waters. This study provides important information for reviewing marine spatial plans of the northern Savu Sea, specifically on managing species fisheries interaction, optimizing surveillance, and regulating marine traffic.

最大熵模型:估计印度尼西亚萨武海北部鲸类栖息地的相对适宜性

了解鲸类分布对于深入了解物种保护管理的关键生态过程是必要的。然而,对印度尼西亚萨武海北部的鲸类栖息地偏好和分布仍知之甚少。我们使用具有五个环境预测因子的最大熵模型来描述萨武海北部七种鲸类物种的栖息地偏好和分布。我们的研究证实,静态预测因子是解释萨武海北部七种鲸类物种栖息地偏好的最重要变量。季节性地,每个鲸类物种都有不同的环境偏好。Globicephala macrorhynchus 喜欢靠近深水区的开阔近岸区域。Stenella attenuata 与近岸栖息地和生产力较高的地区有关。Stenella longirostris 在沿海上升流事件期间更喜欢近岸栖息地。Tursiops truncatus 更喜欢近岸庇护的栖息地。Grampus griseus 栖息地与 200-1,000 m 等深线周围的深度和陡峭梯度高度相关。Feresa attenuata 与深水和较冷的海水温度有关。Pseudorca crassidens 更喜欢有生产水域的保护性海湾。这项研究为审查萨武海北部的海洋空间规划提供了重要信息,特别是在管理物种渔业互动、优化监测和调节海洋交通方面。Feresa attenuata 与深水和较冷的海水温度有关。Pseudorca crassidens 更喜欢有生产水域的保护性海湾。这项研究为审查萨武海北部的海洋空间规划提供了重要信息,特别是在管理物种渔业互动、优化监测和调节海洋交通方面。Feresa attenuata 与深水和较冷的海水温度有关。Pseudorca crassidens 更喜欢有生产水域的保护性海湾。这项研究为审查萨武海北部的海洋空间规划提供了重要信息,特别是在管理物种渔业互动、优化监测和调节海洋交通方面。
