This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Delineation and estimation of the Maugean skate population in Macquarie Harbour, Tasmania". For specific data outputs from this project, please see child records associated with this metadata.<br /> --------------------<br /> <br /> The endangered Maugean skate is now only found in Macquarie Harbour, which has a long history of environmental degradation, and recent research suggests that the population may be declining. However, our current abundance estimation tools are inadequate to determine population status and a new method is needed. This project will use next generation genetic sequencing and novel imaging survey tools to delineate and estimate the size of the Macquarie Harbour Maugean skate population to inform conservation strategies. There is also a need to investigate the evolutionary potential of the Maugean skate to adapt to the changing environmental conditions. This research will address these needs by examining the skate's genetic diversity and fine-scale population structure using whole genome typing, and developing a high-resolution dataset of genome-wide single nucleotide polymorphisms. This genetic approach will help inform adaptive management strategies, such as captive breeding, and enhance our ability to detect differentiated lineages with adaptive potential.<br /> <br /> Outputs<br /> • Tissue sampling results and genome-wide population genetic structure [dataset]<br /> • Adaptive resolution imaging sonar (ARIS) and lidar water column scanning [dataset]<br /> • Final project report [written]

该记录概述了2023年NESP MARINE和沿海枢纽研究计划“塔斯马尼亚州麦格理港的Maugean滑板人口的划定和估计”。有关此项目的特定数据输出，请参阅与此元数据相关的子记录。<br /> ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- <br /> 濒临灭绝的Maugean滑板现在仅在麦格理港口发现，该港口有悠久的环境退化史，最近的研究表明，人口可能正在下降。但是，我们当前的丰度估计工具不足以确定人口状况，需要一种新的方法。该项目将使用下一代遗传测序和新颖的成像调查工具来描述和估计Macquarie Harbour Maugean滑板人群的规模，以告知保护策略。还需要调查Maugean滑板的进化潜力，以适应不断变化的环境条件。这项研究将通过使用整个基因组键入检查滑板的遗传多样性和细数种群结构来解决这些需求，并开发全基因组单核苷酸多态性的高分辨率数据集。这种遗传方法将有助于为适应性管理策略（例如圈养育种）提供信息，并增强我们以自适应潜力检测分化谱系的能力。<br /> <br /> 输出<br /> •组织采样结果和全基因组种群遗传结构[数据集] <br /> •自适应分辨率成像声纳（ARIS）和LIDAR水柱扫描[数据集] <br /> •最终项目报告[书面]
