Genomic evidence of speciation by fusion in a recent radiation of grasshoppers
<p><span>Post-divergence gene flow can trigger a number of creative evolutionary outcomes, ranging from the transfer of beneficial alleles across species boundaries (<em>i.e.</em>, adaptive introgression) to the formation of new species (<em>i.e.</em>, hybrid speciation). While neutral and adaptive introgression has been broadly documented in nature, hybrid speciation is assumed to be rare and the evolutionary and ecological context facilitating this phenomenon still remains controversial. Through combining genomic and phenotypic data, we evaluate the hypothesis that the dual feeding regime (based on both </span><span>scrub legumes and gramineous herbs)</span><span> of the taxonomically controversial grasshopper <em>Chorthippus saulcyi</em> <em>algoaldensis</em> resulted from hybridization between the sister taxa </span><em><span>C. binotatus </span></em><span>(that exclusively feeds on scrub legumes) and </span><em><span>C. saulcyi</span></em><span><em> </em>(that only feeds on </span><span>gramineous herbs)</span><span>. Genetic clustering analyses and inferences from coalescent-based demographic simulations confirm that <em>C. s. algoaldensis</em> represents an independently evolving lineage and support the ancient hybrid origin of this taxon (<em>ca. </em>1.4 Ma), which sheds light on its uncertain phylogenetic position and might explain its broader trophic niche. We propose a Pleistocene hybrid speciation model where range shifts resulting from climatic oscillations can promote the formation of hybrid swarms and facilitate its long-term persistence through geographic isolation from parental forms in topographically complex landscapes.</span></p>

Finite element mesh of fusion energy heat exchange component: hybrid CAD/IBSim model including a graphite foam interlayer
<p>Image-Based Simulation (IBSim) mesh:<br> A finite element mesh of a conceptual design for a fusion energy heat exchange component (monoblock). The mesh is a hybrid from a computer aided design (CAD) drawing for the pipe and armour and IBSim for the interlayer. The IBSim interlayer is generated directly from a 3D volumetric image of a graphite foam block (KFoam). The 3D image was generated with an X-ray tomography scan performed by Dr Llion Evans with Manchester X-ray Imaging Facility equipment, which was funded in part by the EPSRC (grants EP/F007906/1, EP/F001452/1 and EP/I02249X/1). Conversion of the data to FE mesh was achieved using ScanIP, part of the Simpleware suite of programmes, version 7 (Synopsys Inc., Mountain View, CA, USA).</p> <p>The FE mesh data uses the EnSight Gold file format and may be visualised using Paraview (<a href="https://www.paraview.org">https://www.<strong>paraview</strong>.org</a>).</p> <p>The CT data used for the mesh is available as a separate dataset:</p> <p>This data was used originally for the following publications (please cite if re-using the data):<br> Ll.M.
