The torrent salamanders (Rhyacotritonidae) are a family of headwater-obligate species endemic to the Pacific Northwest. Cascade torrent salamanders (Rhyacotriton cascadae) are one of two species being considered as candidate species for listing under the Federal Endangered Species Act, due to ongoing and projected habitat loss from climate change and timber harvest. The cold, fast-flowing water of the often intermittent headwater streams that they inhabit is crucial for completion of their life cycle, making them at particular risk from decreased snowpack and rising water temperatures. To mitigate these threats, establishing riparian buffers along their streams has been proposed, but their fishless headwater streams are currently not afforded the same protections as fish bearing streams throughout most of their range. To investigate the landscape covariates that impact dispersal and geneflow for R. cascadae, we conducted a landscape genomics study in the H.J. Andrews Long-Term Experimental Research (LTER) site. We collected tissue samples from individuals across the 10km watershed, and used double digest reduced-representation sequencing (ddRADseq) to generate a dataset of single nucleotide polymorphisms (SNPs) from this population. Using our SNP dataset, we investigated the impact of multiple landscape features including topographic roughness, heat load index, and canopy cover on geneflow between sites. As R. cascadae is highly desiccation intolerant, they are thought to use streams as corridors for dispersal. We used our dataset to test this hypothesis, evaluating the relationship between distance to stream and dispersal. We found that, to R. cascadae, not all streams are created equal. The best performing models contained distance to stream, but only when accounting for other landscape features. Our results provide direct guidance to managers wishing to maintain corridors for gene flow, and subsequent population persistence, across the range of this threatened Pacific Northwest salamander.
