NESP MaC Project 2.6 - Mapping critical Australian sea lion habitat to assess ecological value and risks to population recovery

本记录概述了国家环境保护计划海洋和沿海枢纽项目“绘制关键的澳大利亚海狮栖息地地图，以评估种群恢复的生态价值和风险”。有关此项目的特定数据输出，请参阅与此元数据关联的子记录。<br/> <br/> 在过去的40年里，濒临灭绝的澳大利亚海狮的数量下降了60%。在物种范围内的丰度和趋势上存在明显的不均匀分布，这表明来自威胁的局部风险概况在小空间尺度上有所不同。栖息地利用的细微规模差异被认为是这些差异的基础，但关于物种对关键栖息地的依赖及其对人类影响的脆弱性的知识有限。该项目将在海狮身上部署水下摄像机，以识别和绘制它们的关键栖息地，评估它们的生态价值，并确定对种群的风险。结果将提高我们对海狮种群威胁的了解，并支持未来的保护行动，以恢复该物种。<br/> <br/> 产出<br/> ·从海狮部署的标签跟踪数据：位置、深度、时间、温度、光线、加速度[数据集]<br/> ·海狮配置的摄像机拍摄的带有时间戳的视频片段[数据集]<br/> ·最终项目报告[书面]

This record provides an overview of the NESP Marine and Coastal Hub project "Mapping critical Australian sea lion habitat to assess ecological value and risks to population recovery". For specific data outputs from this project, please see child records associated with this metadata.<br /> --------------------<br /> <br /> Populations of the endangered Australian sea lion have declined by &gt;60% over the last 40 years. There is a marked uneven distribution in abundance and trends across the species range, suggesting that localised risk profiles from threats vary at small spatial scales. Fine scale differences in habitat use are thought to underpin these differences, yet knowledge about the species dependency on key habitats and their vulnerability to human impacts is limited. This project will deploy underwater cameras onto sea lions to identify and map their critical habitats, assess their ecological value and identify risks to populations. Results will improve our understanding of threats to sea lion populations and support future conservation actions to recover the species.<br /> <br /> Outputs<br /> • Tracking data from sea lion-deployed tags: location, depth, time, temperature, light, acceleration [dataset]<br /> • Timestamped video footage from sea lion-deployed cameras [dataset]<br /> • Final project report [written]
