Westley Diane Whited Andrew R. Whiteley Fred W. Allendorf Ryan Kovach 2017 <p>We appreciate the comments of Young et al. (2017) on our recent paper (Muhlfeld et al., 2017) concerning spatiotemporal dynamics of hybridization between native westslope cutthroat trout (<i>Oncorhynchus clarkii lewisi</i>; WCT) and introduced coastal rainbow trout (<i>Oncorhynchus mykiss irideus</i>; RBT). Nevertheless, we believe there is no evidence for “ecological segregation” protecting WCT from hybridization with invasive RBT. Here we consider their three major arguments for ecological segregation and find their conclusions invalid.</p> application/pdf 10.1111/gcb.13825 en Wiley No evidence for ecological segregation protecting native trout from invasive hybridization article
