Milwaukee Public Museum Crayfish Expedition 3

The Milwaukee Public Museum holds the largest collection of crayfish from Wisconsin. These specimens formed the foundation of  The Crayfish and Shrimp of Wisconsin by Joan Jass and H. H. Hobbs III. As aquatic ecosystems are impacted by humans, crayfish could potentially become invasive species as they populate new habitats, or native populations may decline, risking extinction.This expedition will give scientists the tools they need to answer these questions. These labels can be challenging to interpret--please see our updated tutorials. Click on "View tutorial" to download the PDFs. Thank you for helping us transcribe our labels! This expedition of 497 tasks is fully transcribed and validated. This data resource is harvested periodically into the main occurrence index.

密尔沃基公共博物馆（Milwaukee Public Museum）藏有威斯康星州规模最大的螯虾（crayfish）标本馆藏。这些标本是琼·雅斯（Joan Jass）与H·H·霍布斯三世（H. H. Hobbs III）所著专著《威斯康星州的螯虾与虾类（The Crayfish and Shrimp of Wisconsin）》的核心研究基础。随着水生生态系统遭受人类活动干扰，螯虾可能在入侵新栖息地后成为外来入侵物种，亦或本土螯虾种群数量持续下降并面临灭绝风险。本次标注项目将为科学家解答上述科学问题提供必要的研究工具。部分标本标签的解读存在一定难度，请参阅我们更新后的官方教程。点击「查看教程（View tutorial）」即可下载相关PDF文件。感谢您协助我们完成标本标签的转录工作！本次包含497项任务的标注项目已完成全部转录与校验工作。本数据集资源将定期汇入主物种出现记录索引（main occurrence index）。
