Wyoming crayfish assemblages 1969 - 2020

Crayfish have experienced extensive community reorganization as a result of global change, with some species becoming globally invasive while others have become rare or extinct. We combined historical and contemporary sampling data to determine temporal trends of crayfish assemblages of Wyoming, United States (1969–2020). The dataset includes previous statewide surveys and more narrow studies focusing on locations like Yellowstone National Park, individual native species, or newly discovered populations of invasive Faxonius rusticus. It also includes data from a 2020 statewide sampling effort of crayfish assemblages at 289 sites between April and November 2020.

受全球变化影响，螯虾（crayfish）类群发生了广泛的群落重构，部分物种已成为全球性入侵物种，而另一些则日趋稀有甚至灭绝。本研究整合历史与当代采样数据，以解析美国怀俄明州螯虾群落的时间变化趋势（1969年—2020年）。本数据集涵盖既往全州范围调查，以及聚焦于黄石国家公园、单一本土物种或新发现的入侵性Faxonius rusticus种群等对象的专项研究。此外，数据集还包含2020年4月至11月间，针对怀俄明州289个采样点开展的螯虾群落全州普查数据。
