Dataset for: Conservation genomics of federally endangered Texella harvester species (Arachnida, Opiliones, Phalangodidae) from cave and karst habitats of central Texas
<p>Genomic-scale data for non-model taxa are providing new insights into landscape genomic structuring and species limits, leading to more informed conservation decisions, particularly in taxa with extremely restricted microhabitat preferences and small geographic distributions. This study applied sequence capture of ultraconserved elements (UCEs) to gather genomic-scale data for two federally endangered <i>Texella</i> harvester species distributed in Edwards Formation cave and karst habitats of central Texas, near Austin. We gathered UCE data for 51 <i>T. reyesi </i>specimens from 46 different caves, seven <i>T. reddelli</i> specimens from five caves, and from relevant outgroup species. For these UCE data we applied a combination of phylogenomic, multispecies coalescent phylogenetic, and single-nucleotide polymorphism (SNP) machine-learning analyses. We found that samples of <i>T. reddelli</i> and <i>T. reyesi</i> together form a single clade in phylogenetic analyses, but that <i>T. reddelli </i>samples are not recovered as monophyletic. Instead, <i>T. reddelli </i>samples from three northern caves are embedded within a larger <i>T. reyesi</i> genetic clade. Significantly, the genetic structuring of all samples closely follows geologic barriers defined for the region and formalized as karst fauna regions (KFRs). One exception is the Jollyville Plateau KFR, which includes two divergent, non-sister genetic lineages. Levels of troglomorphy, here assessed by a simple scoring of corneal and retinal development, also closely follows clade (and geographic) boundaries, implying that divergent genetic lineages might also have distinct ecologies. Overall, our study has important taxonomic implications, is the first to explore (and validate) regional KFR boundaries using intraspecific genetic data, and provides essential data for future management decisions involving these federally endangered species.</p>

FIGURE 1. Phylogenetic tree of Cyphellophora based on the combined data set of ITS and nucLSU with Phaeomoniella prunicola as outgroup. Clades with Bayesian probabilities>0.95 and bootstrap support values>60% are indicated at the nodes (ML/BI). For the Bayesian inference, the best-fit model (GTR+I+G with ingamma-distributed rate) for ITS and nucLSU were selected in MrModeltest 2.3. The phylogenetic tree obtained from Bayesian analyses was using MrBayes 3.0b4. Thickened branches represent posterior probabilities (>0.95) from BI. The scale bar indicates 0.1 substitutions per site. The two new species from this study are marked in bold. The type specimens are indicated with an T.
