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

本记录概述了国家环境保护计划海洋和沿海枢纽研究计划2023年项目“东部灰鲨种群数量和趋势”。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/> 东部种群灰鲨，金牛座，根据1999年EPBC法案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进行持续研究的优先事项，这些研究构成了这一拟议项目的基础。这包括研究以完善东澳大利亚灰鲨种群的数量和趋势估计，并研究将活动范围扩大到维多利亚水域的可能性。这将增加最近的年龄和生长估计的价值，并检查青少年的表观遗传老化。这些信息对于评估当前的保护安排非常重要，例如空间关闭。<br/> <br/> 产出<br/> ·幼年灰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]
