NESP MaC Project 3.13 - Eastern Grey Nurse Shark population abundance and trend

该记录概述了NESP海洋和沿海枢纽研究计划2023项目“东部灰护士鲨种群丰度和趋势”。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 /> <br /> 根据1999年的EPBC法案，东部的灰护士鲨Carcharius taurus被列为极度濒危物种，2002年实施了一项确保恢复的战略，制定了第一个恢复计划。2014年更新的恢复计划确定了需要持续研究的优先事项，这些研究构成了拟议项目的基础。这包括研究，以完善丰富和趋势估计为东澳大利亚人口的灰护士鲨和审查的潜力，范围扩大到维多利亚州的沃茨。这将增加最近年龄和生长估计的价值，并审查青少年的表观遗传老化。这些资料对于评估目前的保护安排，如禁渔区的评估十分重要。<br /> <br /> 输出<br /> ·青少年灰护士鲨的组织样本和提取产品[数据集]<br /> ·最终项目报告[书面]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Eastern Grey Nurse Shark population abundance and trend". For specific data outputs from this project, please see child records associated with this metadata.<br /> --------------------<br /> <br /> The eastern population of grey nurse shark, Carcharius taurus, is listed as Critically Endangered under the EPBC Act 1999, and a strategy to ensure recovery was implemented in 2002 with the development of the first recovery plan. The recovery plan updated in 2014 identifies priorities that require ongoing research that form the basis of this proposed project. This includes research to refine the abundance and trend estimate for the eastern Australian population of grey nurse shark and examine the potential for range expansion into Victorian waters. This will add value to recent age and growth estimates and examine epigenetic ageing of juveniles. Such information is important to inform the assessment of current conservation arrangements such as spatial closures.<br /> <br /> Outputs<br /> • Tissue samples and extracted products from juvenile grey nurse sharks [dataset]<br /> • Final project report [written]
