The Lyman Alpha Reference Sample. XVI. Global 21cm HI properties of Lyman-alpha emitting galaxies.
<p>21cm maps and spectra of galaxies in the Lyman Alpha Reference Samples (LARS and eLARS). The field of view has been tailored to show the full extent of the main SoFIA 2 detection. In each FIgure, the top left panel shows DECaLS optical composite image with HI column density contours at level $1.0\times2^n \times10^{19}\,\textrm{cm}^{-2}$, with $n=0,1,2,...,5$ overlaid. The blue solid line shows the regions with SNR>3. Contours fully included in the SNR>3 mask are shown in white, low signal-to-noise contours are shown in gray. A gray cross indicates the position of the galaxy according to optical coordinates, a synthesized beam shaped aperture centred on these coordinates was used to extract HI properties in the center. The top right panel shows column density maps with the same contours as on the previous panel overlaid. The middle left pannel shows the moment-1 map. The middle right panel shows the linewidth map. The bottom pannel shows the total 21cm spectrum (gray) and beam-extracted 21cm spectrum (black). Velocity centroids are indicated by a vertical solid line, and velocity at half width on either side of the peaks by dashed lines, in either gray or black for the total or beam extraction respectively. In the Figure for eLARS05, the object on the bottom left of the top left panel is a separate detection by SoFIA-2.</p>

Data from: Phylogenetic sampling affects evolutionary patterns of morphological disparity
<p>Cladistic character matrices are routinely repurposed in analyses of morphological disparity. Unfortunately, the sampling of taxa and characters within such datasets reflects their intended application - to resolve phylogeny, rather than distinguish between phenotypes - resulting in tree shapes that often misrepresent broader taxonomic and morphological diversity. Here we use tree shape as a proxy to explore how sampling can affect perceptions of evolving morphological disparity. Through analyses of simulated and empirical data, we demonstrate that sampling can introduce biases in trait space occupation between clades that are predicted by differences in tree symmetry and branch length distribution. Symmetrical trees with relatively long internal branches predict more expansive patterns of trait space occupation. Conversely, asymmetrical trees with relatively short internal branches predict more compact distributions. Additionally, we find that long external branches predict greater phenotypic divergence by peripheral morphotypes. Taken together, our results caution against the uncritical repurposing of cladistic datasets in disparity analyses. However, they also demonstrate that when morphological diversity is proportionately sampled, differences in tree shape between clades can speak to genuine differences in morphospace occupation. While cladistic datasets may serve as a useful starting point, disparity datasets must attempt to achieve uniformity of lineage sampling across time and topology. Only when all potential sources of bias are accounted for can genuine evolutionary phenomena be distinguished from artefactual signals. It must be accepted that the non-uniformity of the fossil record may preclude representative sampling and, therefore, a faithful characterization of the evolution of morphological disparity.</p>

Data for: PickMe: sample selection for species tree reconstruction using coalescent weighted quartets
<p>After collecting large data sets of many genes for many species for phylogenomics studies, researchers may make ad hoc decisions about which genes or samples to include in a species tree reconstruction analysis based on various parameters, including the amount of missing data. Optimally, sampling would be maximized, but it can be difficult for empiricists to determine where to draw the line for sample inclusion when data sets are incomplete. Under the multispecies coalescent model, in which the dominant quartet topology displayed across gene trees matches the topology of that quartet on the species tree, we propose a Bayesian framework to select samples for which there is support for inclusion in a species tree analysis. Given a collection of gene trees, a posterior probability is assigned to each quartet topology, describing the likelihood that the species tree displays this topology. From this, individual samples are assigned reliability scores computed as the average of a rescaling of the posterior probabilities. These weights are used in a Bayesian framework in an algorithm called PickM}, which determines which individuals should be included in a species tree analysis. To illustrate the efficacy of this tool, PickMe is applied to gene trees generated from target capture data from milkweeds. PickMe indicates that more samples could have reliably been included in a previous milkweed phylogenomic analysis than the authors analyzed, without access to a formal decision-making procedure. Thus, PickMe will be a valuable addition to data analysis pipelines for phylogenomics studies.</p>

Sanger sequencing traces of specific exons of the Sm.TRPM_PZQ gene from schistosome field samples
<p>Praziquantel (PZQ) is the only drug available to treat schistosomiasis, which is caused by schistosome blood flukes. In <em>Schistosoma mansononi</em>, the transient receptor potential (TRP) channel Sm.TRPM<sub>PZQ</sub> is strongly suspected to be the target of PZQ. Our <a href="https://doi.org/10.1101/2021.06.09.447779">genetic analysis of <em>S. mansoni</em> response to PZQ</a> revealed a QTL on its chromosome 3 which contains the <em>Sm.TRPM<sub>PZQ</sub></em> gene, strongly suggesting that <em>Sm.TRPM<sub>PZQ</sub></em> could be responsible for PZQ resistance. Therefore, understanding the natural variation in this gene and identifying potential resistance alleles will be a valuable tool for monitoring mass treatment programs aimed at schistosomiasis elimination.</p> <p>We investigated our schistosome collection to examine mutations present in <em>Sm.TRPM<sub>PZQ</sub></em> in natural schistosome populations. We analyzed exome sequencing data from 259 miracidia, cercariae or adult parasites from 3 African countries (Senegal, Niger, Tanzania), the Middle East (Oman) and South America (Brazil). We were able to sequence 36/41 exons of <em>Sm.TRPM<sub>PZQ</sub></em> from 122/259 parasites on average (s.e. = 18.65). We identified several mutations in critical areas of the channel. However, these mutations were supported by a limited number of reads only and required confirmation by Sanger sequencing.</p> <p>The present dataset corresponds to the sequencing effort done on specific exons which carried the mutations to be confirmed. We generated PCR products which were sequenced on on ABI sequencer using Eurofins Genomics services. The SCF files were then analyzed using PolyPhred (see manuscript for details about PCR conditions and data analysis). The trace files are available in the traces folder. Each filename carries a barcode which corresponds to a combination of sample, exon, and primer. All the combinations and corresponding barcodes are listed in the barcode_list.tsv file.</p> <p>Table header details of the barcode list:</p> <ul> <li><em>Sample</em>: the name of sample. The sample coding is as follows: species.country_patientID. BR: Brazil, SN: Senegal, NE: Niger, TZ: Tanzania, OM: Oman.</li> <li><em>Exon</em>: the exon targeted. The exon number corresponds to the exon number of isoform 5 and not the exon number of the gene.</li> <li><em>Barcode</em>: the barcode provided by Eurofins Genomics.</li> <li><em>Primer</em>: the primer used for sequencing. F: forward, R: reverse.</li> </ul>
