Bay of Quinte Long Reach - Cladoceran Size Structure Paleolimnology Project

These data were collected as a part of a larger paleolimnological assessment of the Bay of Quinte, Lake Ontario. The goal of these specific data was to measure change in cladoceran size structure over time in response to historical trophic alteration. We wanted to identify the best indicators of trophic change that could then be applied to further paleolimnological investigations of the Bay of Quinte and coupled with other assemblage metrics (e.g., relative abundance, diversity, and concentration) to provide a comprehensive overview of long-term change.<br>These data were generated and analysed as part of the following work:<br>Armstrong, I., &amp; Cumming, B. F. (Submitted) Novel methods in cladoceran size structure analysis reveal ~60 years of trophic change in a sediment core from Bay of Quinte, Lake Ontario. <i>Freshwater Biology</i>

本数据集采集自安大略湖昆特湾的大型古湖沼学（paleolimnological）评估项目。本次特定数据集的核心研究目标，是量化枝角类（cladoceran）体型结构随时间的变化，以表征历史营养状态扰动带来的响应效应。本研究旨在筛选出最优的营养状态变化指示物，后续可将其应用于昆特湾的进一步古湖沼学调查，并结合其他集合体指标（如相对丰度、多样性与浓度），全面呈现该区域长期生态变化的完整图景。<br>本数据集的生成与分析依托以下研究成果：<br>阿姆斯特朗（Armstrong, I.）与卡明（Cumming, B.
