NESP MB Project A9 - Grey Nurse Shark CK-MR Population Estimate – East Coast

本记录概述了NESP海洋生物多样性中心项目A9 -“灰护士鲨CK-MR种群估计-东海岸”的范围和研究成果。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 /> <br /> 对2002年灰护士鲨国家恢复计划（DEWHA 2009）的审查得出结论，无法确定东海岸种群是否显示出任何恢复迹象（能源部2014）;建议为该物种制定新的恢复计划。新的恢复计划（能源部2014年）的主要目标是提高对GNS种群状况的认识。这将需要对人口规模和趋势进行可靠的估计，而迄今为止还没有提供这种估计。该项目将使用遗传SNP数据为近亲属标记重捕分析提供信息，以估计种群规模和趋势，并为东海岸灰护士鲨种群的未来监测策略提供指导。<br /> <br /> 计划产出<br /> ·完善和综合CK-MR和物种人口统计数据的工具，用于在全国范围内对一个主要受威胁物种进行种群评估（将在本项目下开发的知识与在NESP下对广盐鲨鱼和白色鲨鱼采用的类似技术相结合）。<br /> ·将对东澳大利亚州的灰护士鲨种群规模和趋势进行全国性的（人口普查）估计，以完成国家恢复计划的最高优先行动。<br /> ·确定国家战略，以指导今后对灰护士鲨种群的监测。 <br /> ·该项目将为科学文献提供经同行审查的补充，这将增加对制定和实施政策的科学支持，以支持澳大利亚海洋环境的生态可持续管理。

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A9 - "Grey Nurse Shark CK-MR Population Estimate – East Coast". For specific data outputs from this project, please see child records associated with this metadata.<br /> <br /> --------------------<br /> <br /> A review of the 2002 National Recovery Plan for Grey Nurse Shark (DEWHA 2009) concluded it was not possible to determine if the east coast population had shown any signs of recovery (DoE 2014); recommending a new recovery plan be developed for this species. A primary objective of the new recovery plan (DoE 2014) is to improve knowledge of GNS population status. This will require a robust estimate of population size and trend – something that has not been provided to date. This project will use genetic SNP data to inform close kin-mark recapture analysis to estimate population size and trend, and provide guidance on future monitoring strategies for the east coast population of grey nurse shark. <br /> <br /> Planned Outputs<br /> • Tools to refine and integrate CK-MR and species demographic data for population assessments of a key threatened species at a national scale (combining knowledge developed under this project combined with similar techniques being applied under NESP to euryhaline sharks and white sharks). <br /> • A national estimate of (census) population size and trend for the eastern Australian population of grey nurse shark will be developed to fulfil the highest priority actions of the National Recovery Plan.<br /> • Identify national strategies to guide future monitoring of grey nurse shark populations. <br /> • The project will provide peer-reviewed additions to the scientific literature that will add to the science-support for the development and implementation of policies to support the ecologically sustainable management of Australia’s marine environment.
