The Engineer Research and Development Center (ERDC) of the U.S. Army Corps of Engineers is inviting applications for a federal grant titled "Statistical Evaluation of Adaptive Management Study Duration," aimed at assessing fish populations in Pool 22 of the Upper Mississippi River. The project seeks to conduct a statistical power analysis to determine the necessary sampling size to detect changes in native fish populations, thereby improving habitat connectivity affected by navigation structures. This initiative is crucial for enhancing ecological integrity and informing future conservation efforts, with an estimated total program funding of $169,905 and a single award anticipated. Interested non-federal partners of the Great Rivers Cooperative Ecosystems Studies Unit must submit initial expressions of interest by July 26, 2025, followed by full proposals due by August 11, 2025. For further inquiries, applicants can contact Kisha M. Craig at kisha.m.craig@usace.army.mil or by phone at 601-634-5397.
