Summary

The Arkansas River Shiner (ARS), Notropis girardi, is a federally threatened minnow that now occurs natively in modest numbers only in the South Canadian River, following decades of range contraction and population losses. The remaining populations are at increasing risk as global change is expected to impact the upper and middle South Canadian River with a rise in temperature as much as 4-6 F and a decrease in precipitation from 10 to 35 % in this century. The primary objective of this project was to evaluate potential effects of habitat and environmental change on Arkansas River shiners by examination of habitat use and availability at several spatial scales using both historical and recently-collected data from seven sites within [...]

Purpose

The predicted changes in climatic patterns that will affect the Canadian River basin will undoubtedly affect habitat available to ARS. The objective of this study was to evaluate probable changes in habitat availability for use by ARS and other fishes in response to changes in flow or river discharge. To address this, we used historical and contemporary data on habitat availability and use by ARS and other small-bodied riverine fishes from studies conducted at several sites in the South Canadian River within the boundaries of the GPLCC. We also performed detailed monthly habitat surveys at one site from September 2012 through August 2013. This site historically had a large population of ARS, although recent collections here have yielded very few ARS.
