The USGS is offering a funding opportunity to a CESU partner for research on ⿿Characterizing Hybridization of the Pallid Sturgeon and Evaluating Analyses to Improve Species Identification and Assess the Threat of Introgression.⿝ Considerable uncertainty exists regarding the nature, frequency and extent of hybridization between the endangered pallid sturgeon and the common shovelnose sturgeon throughout its range. Resolving this uncertainty is crucial to developing management strategies to recover endangered sturgeon and to prioritize management actions in the large river ecosystems where they reside. Current genetic markers and analyses are insufficient to adequately characterize hybridization between these species and research is needed to identify pathways forward to rapidly develop cost-effective genetic tools.
