Data from: Species identity and cave-dwelling tree hyraxes of the Kenyan coast
<p><span>The eastern tree hyrax is thought to be a solitarily living arboreal species of the forests of East Africa. However, on the coast of Kenya, indigenous forests have been almost entirely cleared, and some of the last tree hyrax populations live in limestone rocky formations and caves. Interestingly, they seem to be living in social groups. Here, we describe and document photographically these unique tree hyrax populations. We also describe their acoustical communication and their calling activity in three different habitats. Based on these animals' physical appearance and acoustic analyses of their calls, they represent the species eastern tree hyrax, <em>Dendrohyrax</em> <em>validus</em>. Due to immence pressure from humans, the future of these small and isolated, cave-living tree hyrax populations does not seem bright.</span></p>

Data for: Speleothem stable isotopes from 670 - 240 ka ago at Cape Limeworks Cave 1, Robertson, South Africa
<p class="MsoNormal">We present stable oxygen and carbon isotope data (<span>δ<sup>18</sup>O and δ<sup>13</sup>C ) </span>and U-Th chronology data from five speleothems from Cape Limeworks Cave 1 near Robertson, Western Cape, South Africa (33.73S°, 19.77E°). The data set covers the time interval between 240 and 670 ka BP with hiatuses at 630-500 ka and 360-310 ka. Stable isotope ratios range between -6.5 and -3.7 ‰ for <span>δ<sup>18</sup>O and -11.0 and -8.5 ‰ for δ<sup>13</sup>C. Analyses of the dispersion of the δ<sup>18</sup>O and δ<sup>13</sup>C data sets suggest that the highly diverse western part of the Cape Floristic </span>Region experienced climatic stability across several glacial-interglacial cycles when compared to less diverse Mediterranean Climate Regions and the eastern parts of the Cape Floristic Region. This result provides support for the hypothesis that lower extinction rates associated with Pleistocene biome stability may explain the higher diversity in the CFR relative to other MCEs.</p>

Astyanax cavefish body shape coordinates from: Phylogeographic relationships and morphological evolution between cave and surface Astyanax mexicanus populations (De Fillipi 1853) (Actinopterygii, Characidae)
<p>The <em>Astyanax mexicanus</em> complex includes two different morphs, a surface and a cave-adapted ecotype, found at three mountain ranges in Northeastern Mexico: Sierra de El Abra, Sierra de Guatemala, and Sierra de la Colmena (Micos). Since their discovery, multiple studies have attempted to characterize the timing and the number of events that gave rise to the evolution of these cave-adapted ecotypes. Here, using RAD-seq and genome-wide sequencing, we assessed the phylogenetic relationships, genetic structure, and gene flow events between the cave and surface <em>Astyanax</em> <em>mexicanus</em> populations, to estimate the time and mode of evolution of the cave-adapted ecotypes. We also evaluated the body shape evolution across different cave lineages using geometric morphometrics to examine the role of phylogenetic signal vs. environmental pressures. We found strong evidence of parallel evolution of cave-adapted ecotypes derived from two separate lineages of surface fish and hypothesize that there may be up to four independent invasions of caves from surface fish. Moreover, a strong congruence between the genetic structure and geographic distribution was observed across the cave populations, with the Sierra de Guatemala the region exhibiting most genetic drift among the cave populations analyzed. Interestingly, we found no evidence of phylogenetic signal in body shape evolution, but we found support for parallel evolution in body shape across independent cave lineages, with cavefish from the Sierra de El Abra reflecting the most divergent morphology relative to surface and other cavefish populations.</p>

Data for dating in the dark: Elevated substitution rates in cave cockroaches (Blattodea: Nocticolidae) have negative impacts on molecular date estimates
<p>Rates of nucleotide substitution vary substantially across the Tree of Life, with potentially confounding effects on phylogenetic and evolutionary analyses. A large acceleration in mitochondrial substitution rate occurs in the cockroach family Nocticolidae, which predominantly inhabit subterranean environments. To evaluate the impacts of this among-lineage rate heterogeneity on estimates of phylogenetic relationships and evolutionary timescales, we analysed nuclear ultraconserved elements (UCEs) and mitochondrial genomes from nocticolids and other cockroaches. Substitution rates were substantially elevated in nocticolid lineages compared with other cockroaches, especially in mitochondrial protein-coding genes. This disparity in evolutionary rates is likely to have led to different evolutionary relationships being supported by mitochondrial genomes and UCE loci. Furthermore, analyses using relaxed-clock models inferred much deeper divergence times compared with a flexible local clock. Our phylogenetic analysis of UCEs, which is the first genome-scale study to include all nine major cockroach families, unites Corydiidae and Nocticolidae and places Anaplectidae as the sister lineage to the rest of Blattoidea. We uncover an extraordinary level of genetic divergence in Nocticolidae, including two highly distinct clades that separated ~115 million years ago despite both containing representatives of the genus <em>Nocticola</em>. The results of our study highlight the potential impacts of high among-lineage rate variation on estimates of phylogenetic relationships and evolutionary timescales.</p>
