<br />Colorado USA: Southwest Nat., v..34, no. 2, p. 225-231.
<br />
<br />Distribution of the northern red belly dace, Phoxinuseos, in the South Platte River Basin,
<br />Colorado, was historically restricted to a narrow band of stream habitat in the
<br />transition zone along the Front Range of the Rocky Mountains. Phoxinus eos has been
<br />taken only in the West Plum Creek drainage since 1951, where it mainly occupies off-
<br />channellentic habitats that are cool, clear, vegetated, and without large predaceous
<br />fishes. Age and growth, reproduction, and diet characteristics are similar to those
<br />known for population of P. eos in the center of the species' range. The naturally limited
<br />range and habitat of P. eos in Colorado has been much reduced by stream
<br />channelization, reductions in discharge, and changes in water quality. Continued
<br />urban development threatens remaining populations.
