Figure 2 in Genetic differentiation in Scriptaphyosemion geryi (Lambert, 1958) suggests the existence of a species complex
Figure 2. - Consensus tree based on Maximum Likelihood (PHYML), Parsimony (TNT), and Bayesian phylogenetic analysis (number of generation = 6 108, burn-in = 25%). Numbers above or below the branches are percentages of bootstrap values based on 1000 replicates for respectively each method (except for Bayesian inferences where the numbers represent the percentage of trees with best likelihood scores in which the particular node was found). Numbers on the right side of the tree represent genetically-defined clades.

Data from: Potentials of closed contour analysis in species differentiation and holotype designation: a case study on lower Norian (Upper Triassic) conodonts
<p><span>Geometric morphometric approaches become increasingly applied in the fields of biology and paleontology. Taxonomy is a good example, where a long-standing intention of scientists is to eliminate subjectivity as much as possible. In the case of biostratigraphically important conodont elements, the application of such methods is not widespread. Indeed, only a handful of studies attempted to deal with the morphological variance of conodont elements from this aspect. The detailed description of five lower Norian (Upper Triassic) taxa (<em>Ancyrogondolella quadrata, A. rigoi, A. triangularis, A. uniformis</em> and <em>Metapolygnathus mazzai</em>) is presented here based on landmarks and Fourier analysis of the P1 element and keel outlines. Both methods led to similar outcomes regarding taxonomic differentiation and exposing shape variability. Consensus shapes were generated to objectively reveal the typical contour shape of each taxon, which allowed their comparison with each other, and with the members of their respective sample population including the holotypes. The results pointed out that the holotype of a taxon is generally not an average representative, but rather a peripheral form with well-separable morphological characteristics. <em>Ancyrogondolella quadrata</em> and <em>A. rigoi</em> turned out to represent a morphological continuum with ample transitional forms between these two end-members that may cause bias in their biostratigraphic applicability; however, their combined shape variance seems to be too large for uniting them into a single species. Given the results that may be too subtle to realize based solely on qualitative observations, future taxonomic studies and type material designation could greatly benefit from the application of similar methodologies.</span></p>

Fig. 3. Bayesian inference tree based on an analysis of 520 nucleotides of the mitochondrial cytochrome c oxidase 1 gene showing relationships between Spirostreptida species and outgroups (Julida and Callipodida species). Numbers adjacent to taxon names are GenBank accession numbers, and indicate sequences that were downloaded from the NCBI Genbank. This tree was congruent in structure with maximum parsimony and neighbour-joining analyses of the same dataset. Nodal support values are indicated as (posterior probability / maximum parsimony bootstrap / neighbour-joining bootstrap).
Differentially-expressed genes in blood in response to lipopolysaccharide in three rodent species
<p>Infection tolerance in rodents was examined by injecting single-dose lipopolysaccharide (LPS) to induce inflammation in <span><em>Peromyscus</em> <em>leucopus</em></span><span> (LL stock), the white-footed deermouse also reservoir for Lyme disease and </span><span><em>Mus</em> <em>musculus</em></span><span> (outbred CD-1 breed), the house mouse, and </span><span><em>Rattus</em> <em>norvegicus</em></span><span>, the brown rat (Fischer strain). Reaction to LPS was analyzed in the blood of challenged rodents and compared to control animals. As natural reservoirs of zoonoses deermice show significant anti-inflammatory response as described in "An Infection-Tolerant Mammalian Reservoir for Several Zoonotic Agents Broadly Counters the Inflammatory Effects of Endotoxin" (</span><a href="https://doi.org/10.1128/mBio.00588-21)" rel="noopener"><span>https://doi.org/10.1128/mBio.00588-21)</span></a><span>. The project and the description of the samples are described under the following NCBI BioProjects: PRJNA975149 (</span><a href="https://www.ncbi.nlm.nih.gov/bioproject/PRJNA975149" rel="noopener"><span>https://www.ncbi.nlm.nih.gov/bioproject/PRJNA975149)</span></a><span> for mouse and deermouse and PRJNA973677 (</span><a href="https://www.ncbi.nlm.nih.gov/bioproject/PRJNA973677)" rel="noopener"><span>https://www.ncbi.nlm.nih.gov/bioproject/PRJNA973677)</span></a><span>. This project is a follow-up project focusing on the transcriptomic analysis of the whole blood bulk RNA-seq and further analysis of differentially expressed genes (DEG) between the treatment arm and controls. Complete fold change and false discovery rate for all three rodent species used for the current Dryad set are previously published (<a href="https://doi.org/10.7280/D1470Z">https://doi.org/10.7280/D1470Z</a>). Here we report that deermice tolerance to infection is partly due to lower expression of interferon-gamma in comparison to mice and rats. <br></span></p>
