During Pleistocene, the Laurentide ice sheet rearranged and diversified biotic distributions in eastern North America, yet had minimal physical impact in western North America where lineage…
Does morphology predict ecology? Hypothesis testing within a freshwater stream fish assemblage
Ecomorphological analyses appear to be a valid assay for structure within fish assemblages only when limited to within-family comparisons (where the effects of history appear less significant) when many different families are involved in the analysis.

Small Fish in a Large Landscape: Diversification of Rhinichthys osculus (Cyprinidae) in Western North America
The map of 112 restriction sites in the mitochondrial DNA genome of the Speckled Dace suggested at least three separate ichthyofaunal invasions of California, as well as a Bonneville Basin fragmented by a north-south connection between southeastern Idaho and the Colorado River.
Migration and sexual selection in Ambystoma jeffersonianum

Early response to cues of temperature and precipitation, and continued movement under declining nocturnal temperatures enabled males to arrive at the pond sooner and in greater numbers than females, who frequently moved later and under prolonged periods of favorable conditions.
