Canadian freshwater mussels and their host associations

Freshwater mussels (order Unionida) are one of the world’s most imperiled taxonomic groups of animals. These mussels have an obligate parasitic larval phase wherein the larva (usually, a glochidium) must attach to a suitable host to complete its metamorphosis into a juvenile mussel. This review synthesizes the current knowledge on the hosts of all 55 species of freshwater mussels in Canada compiled from 264 citations, 70 of which were newly identified by this review. As of October 2023, 827 mussel-host interactions have been documented. The Winged Floater and the Lake Floater currently have no known hosts, with 14 other species having only a single associated evidence type. This review provides an updated library of current knowledge on hosts of Canadian unionids, discusses notable trends in the data, and outlines outstanding knowledge gaps to be addressed in future studies. Relatively few studies aimed at identifying unionid hosts have been conducted in Canadian waters. This lack of un..., , # Canadian freshwater mussels and their host associations

## Description of the data and file structure

Dataset contains the known or suspected hosts of Canada's freshwater mussel species (Unionidae, Margaritiferidae) collected from the Illinois Natural History Survey's Mussel Host Database and via literature review. Evidence types were assigned to each interaction in accorance with previously published literature.

淡水蚌类（Unionida，蚌目）是全球最受威胁的动物类群之一。这类蚌类具有专性寄生的幼虫阶段，其幼虫（通常为钩介幼虫（glochidium））必须附着于适宜宿主方能完成变态发育成为幼蚌。本综述整合了当前关于加拿大境内全部55种淡水蚌类宿主的研究知识，数据源自264篇参考文献，其中70篇为本次综述新确认的文献。截至2023年10月，已有827组蚌类-宿主互作被记录。翼形帆蚌（Winged Floater）与湖帆蚌（Lake Floater）目前暂无已知宿主，另有14个物种仅有一种关联证据类型。本综述更新了加拿大蚌类宿主相关的现有知识库，讨论了数据中呈现的显著趋势，并梳理了未来研究亟待填补的知识空白。目前加拿大水域中针对蚌类宿主鉴定的相关研究相对匮乏，此类研究缺口尚未……，
