Supporting data for "Unveiling Vertebrate Development Dynamics in Frog Xenopus laevis using Micro-CT Imaging"
<p>The dataset contains X-ray Micro Computed Tomography data of Xenopus laevis frog. There are twenty datasets of ten individual animals. Each animal was CT scanned twice – once as a native scan to visualize the hard tissues, and once contrast-stained to visualize the soft tissues. The datasets include nine developmental stages (NF44-45, NF52, NF53, NF54, NF57, NF59, NF62, NF66 and adult). There are two adults, one male and one female. The CT data (in 8bit .tiff format compressed as .tar.gz files) are supported by .stl files created from each dataset. The database also includes .stl files of selected structures of interest (body, skeleton, skull, brain and guts of individual animals).</p>

Does the spatial sorting of dispersal traits affect the phenotype of the non-dispersing stages of the invasive frog Xenopus laevis through coupling?
<p>Over ten weeks, we surveyed the development of <em>X. laevis</em> tadpoles in the French invasive range by conducting experiments in outdoor mesocosms and in laboratory microcosms, from free-swimming larvae to metamorphosis. We tested the effect of the location of the parental pond in the colonised range (core or periphery) on morphological traits related to dispersal (SVL and hind limb length), time to metamorphosis (development) and survival to metamorphosis. This excel spreadsheet contains the metadata and data spreadsheets used in the analysis. In addition to the first metadata sheet, the file contains nine additional sheets each containing data used in the separate analysis as outlined in the manuscript. </p>
TAIL-seq for Xenopus laevis oocytes and embryos in various conditions (internal ID: ms97)
<p>This dataset contains the raw sequencing data from a TAIL-seq run for Xenopus laevis embryos. The cluster intensities of fluorescence signals are repacked as an HDF5 formatted file, then split into multiple parts to fit in the dataset size limitation of the Zenodo.</p>
Data from: Lower jaw modularity in the African Clawed Frog (Xenopus laevis) and Fire Salamander (Salamandra salamandra gigliolii)
<p>Modularity describes the degree to which the components of complex phenotypes vary semi-autonomously due to developmental, genetic, and functional correlations. This is a key feature underlying the potential for evolvability, as it can allow individual components to respond to different selective pressures semi-independently. The vertebrate lower jaw has become a model anatomical system for understanding modularity, but to date, most of this work has focused on the mandible of mammals and other amniotes. In contrast, modularity in the mandible of lissamphibians has been less well-studied. Here, we used geometric morphometrics to quantify the static (intraspecific) modularity patterns in <em>Xenopus laevis</em> and <em>Salamandra salamandra gigliolii.</em> We tested developmental and functional hypotheses of modularity and demonstrate that both species exhibit significant modularity. Functional modularity was supported in <em>Xenopus</em>, yet the lack of definitive support for both the developmental and functional hypotheses in <em>Salamandra</em> suggests influences on modularity are much more complex. Allometry has a small yet significant impact on lower jaw shape in both taxa and sex has a significant effect on shape in <em>Xenopus</em>. The high modularity seen in both species mimics the results of other studies on the amphibian cranium, suggesting that modularity is a ubiquitous feature of the tetrapod jaw.</p>

Data from: Pan-African phylogeography of a model organism, the African clawed frog "Xenopus laevis"
The African clawed frog Xenopus laevis has a large native distribution over much of sub-Saharan Africa and is a model organism for research, a proposed disease vector, and an invasive species. Despite its prominent role in research and abundance in nature, surprisingly little is known about the phylogeography and evolutionary history of this group. Here we report an analysis of molecular variation of this clade based on 17 loci (one mitochondrial, 16 nuclear) in up to 159 individuals sampled throughout its native distribution. Phylogenetic relationships among mitochondrial DNA haplotypes were incongruent with those among alleles of the putatively female-specific sex-determining gene DM-W, in contrast to the expectation of strict matrilineal inheritance of both loci. Population structure and evolutionarily diverged lineages were evidenced by analyses of molecular variation in these data. These results further contextualize the chronology, and evolutionary relationships within this group, support the recognition of X. laevis sensu stricto, X. petersii, X. victorianus, and herein re-validated X. poweri as separate species. We also propose that portions of the currently recognized distributions of X. laevis (north of the Congo Basin) and X. petersii (south of the Congo Basin) be reassigned to X. poweri.
