FIGURE 1 in Molecular Systematics of Redband Trout from Genome-Wide DNA Sequencing Substantiates the Description of a New Taxon (Salmonidae: Oncorhynchus mykiss calisulat) from the McCloud River
FIGURE 1. Map of key features and distributions of key lineages in this study. The distribution of Coastal Rainbow Trout (Oncorhynchus mykiss irideus) is shown in grey shading. Other lineages are labeled in different colors. Distributions were retrieved from the PISCES database (pisces.ucdavis.edu, "Historic Range—Expert Opinion") except for Warner Lakes Redband Trout (O. m. ssp.), which is represented by a polygon of hydrologic unit code (HUC) 17120007. Sampling locations used in phylogenetic analyses are indicated with a four-letter code that corresponds to Table 1 and Supplemental Table S1. Samples of O. m. gairdnerii from Idaho are not shown.
FIGURE 5 in Molecular Systematics of Redband Trout from Genome-Wide DNA Sequencing Substantiates the Description of a New Taxon (Salmonidae: Oncorhynchus mykiss calisulat) from the McCloud River
FIGURE 5. Maximum Likelihood (ML) tree (A) and ML consensus tree (B). In both panels subspecies of Rainbow Trout (Oncorhynchus mykiss) are indicated along with members of the Golden Trout Complex. McCloud River Redband Trout (O. m. calisulat, ssp. nov.) and Sacramento Redband Trout (O. m. stonei) are indicated with bold text. Individual sample names are provided at tips and further described in Table 1. In 5A, nodes receiving Shimodaira-Hasegawa approximate Likelihood Ratio Test scores> 80 and bootstrap support (BS)> 95% are indicated with a diamond. In 5B, two spans of bootstrap support are presented, with 100%> BS> 95% as solid black circles and 95%> BS> 90% as grey circles at nodes.

FIGURE 4. Admixture plots from McCloud river trout and other Redband Trout in population genetics dataset. Admixture results from NGSAdmix for genetic clusters (K) from 2-4 with the subset of samples collected as Redband Trout. Sample size of 204, optimal K = 2. The x-axis labels are labeled according to watershed.
FIG. 3 in Few Impacts of Introduced Cutthroat Trout (Oncorhynchus clarki) on Aquatic Stages of Boreal Toads (Anaxyrus boreas boreas)
FIG. 3. Estimated relationships between Cutthroat Trout habitat use and water depth (a), vegetation density (b), and temperature (c) by using the most parsimonious occupancy model, Ψ(size + depth + veg + temp), p(.), during the embryo stage of Boreal Toad development. Relationships with each covariate is plotted using the average values of other covariates. The dashed line designates the relationship for small Cutthroat Trout, and the solid line represents the relationships for large Cutthroat Trout. Shaded areas represent 95% confidence intervals. In (a) and (b), the circles indicate the vegetation density and predicted use at the three egg mass locations. In (c), the squares indicate the average morning temperatures and predicted use at the three egg mass locations. The triangles represent the same for the average evening temperatures.

FIG. 1. Map of Rocky Mountain National Park and its major water bodies. The two study sites, Spruce Lake and Fay Lakes, are denoted by black triangles.
FIG. 2 in Few Impacts of Introduced Cutthroat Trout (Oncorhynchus clarki) on Aquatic Stages of Boreal Toads (Anaxyrus boreas boreas)
FIG. 2. Photograph of two caged Boreal Toad egg mass halves at Spruce Lake. The paired exposed egg mass halves are not visible, but located directly adjacent to each cage.
A new genomic resource to enable standardized surveys of SNPs across the native range of brook trout (Salvelinus fontinalis)
<p>Understanding how genetic diversity is distributed across spatiotemporal scales in species of conservation or management concern is critical for identifying large-scale mechanisms affecting local conservation status and implementing large-scale biodiversity monitoring programs. However, cross-scale surveys of genetic diversity are often impractical within single studies, and combining datasets to increase spatiotemporal coverage is frequently impeded by using different sets of molecular markers. Recently developed molecular tools make surveys based on standardized SNP panels more feasible than ever but require existing genomic information. Here, we demonstrate the utility of genome-wide SNPs reflective of range-wide genetic diversity for surveying populations across the native species range. These data can be leveraged to design SNP panels that allow datasets to be combined for large-scale analyses. We develop this resource for brook trout (<em>Salvelinus fontinalis</em>). We performed restriction site-associated DNA sequencing for wild brook trout from 82 locations spanning much of the native range and domestic brook trout from 24 hatchery strains used in stocking efforts. We identified over 24,000 SNPs putatively representing neutral and adaptive regions of the brook trout genome. We explored the ability of these SNPs to resolve relationships across spatial scales, including population structure, hatchery admixture, and outlier loci. Our dataset captures a wide spectrum of genetic diversity in native brook trout, offering a valuable resource for developing SNP panels. We highlight potential applications of this resource with the goal of increasing the integration of genomic information into decision-making for brook trout and other species of conservation or management concern.</p>
