The cutthroat trout (Oncorhynchus clarki) was the only endemic salmonid species across
most of the western United States, and it has severely declined largely due to introduction …

Although reinforcement should enhance reproductive barriers in sympatric species,
sympatric trout species do hybridize. Using mitochondrial and nuclear species markers, we …

Westslope cutthroat trout (Oncorhynchus clarki lewisi, WCT) and introduced rainbow trout
(O. mykiss, RBT) readily hybridize and introgression has occurred in many drainages across …

Throughout its native range, the Yellowstone cutthroat trout (YCT), Oncorhynchus clarkii
bouvieri, is declining dramatically in both abundance and distribution as a result of …

In this study, we electrofished 961 study sites to estimate the abundance of trout (in streams
only) throughout the upper Snake River basin in Idaho (and portions of adjacent states) to …

Managing and conserving native taxa are becoming increasingly challenging because of
