Genomic insights into the chromosomal elongation in a family of Collembola
<p>Collembola is a highly diverse and abundant group of soil arthropods with chromosome numbers ranging from 3 to 11. Tomoceridae is one of the oldest collembolan families, and previous karyotype studies indicated that this family possesses an exceptionally long chromosome. To better understand chromosome size evolution in Collembola, we obtained a chromosome-level genome of <em>Yoshiicerus persimilis</em> with a size of 334.44 Mb and BUSCO completeness of 97.0%. Both genomes of <em>Y. persimilis </em>and <em>Tomocerus qinae</em> (recently published) have an exceptionally large chromosome (ElChr>100 Mb), accounting for nearly one-third of the genome. Comparative genomic analyses revealed a high degree of homology between the two ElChr, with 95.08% (2,224) of 1:1:1 orthologous genes shared between them. The ElChr elongation was caused by segmental duplication and transposon proliferation, with genes in these regions experiencing stronger selection pressure (higher dN/dS) than conserved regions. Enrichment analysis revealed that duplicated genes of ElChr were primarily associated with proliferation and growth, which explains their larger body size. Moreover, inter-genomic synteny analyses indicated that chromosomal fission/fusion events played a crucial role in the evolution of chromosome numbers within Entomobryomorpha. This study provides important insights into the mechanisms of chromosome evolution and offers a valuable omics resource for Collembola.</p>

Seasonal patterns of leaf exsertion, elongation and senescence for Eriophorum vaginatum and Carex bigelowii was measured in mesic tussock tundra sites near Toolik Lake, AK. In addition, the response of both species to NP fertilizer and to variation in site fertility (after track versus non-track areas) were also assayed and compared. The research was done over two full growing seasons.

Data from: Extreme neck elongation evolved despite strong developmental constraints in bizarre Triassic reptiles – implication for neck modularity in archosaurs
<p>The Triassic radiation of vertebrates saw the emergence of the modern vertebrate groups, as well as numerous extinct animals exhibiting conspicuous, unique anatomical characteristics. Among these, members of Tanystropheidae (Reptilia: Archosauromorpha) displayed cervical vertebral elongation to an extent unparalleled in any other vertebrate. Tanystropheids were exceptionally ecologically diverse and had a wide spatial and temporal distribution. This may have been related to their neck anatomy, yet its evolution and functional properties remain poorly understood. We used geometric morphometrics to capture the intraspecific variation between the vertebrae comprising the cervical column among early archosauromorphs, to trace the evolutionary history of neck elongation in these animals. Our results show that the cervical series of these reptiles can be divided into modules corresponding to those of extant animals. Tanystropheids achieved neck elongation through somite elongation and a shift between cervical and thoracic regions, without presacral vertebrae count increase - contrary to crown archosaurs. This suggests a peculiar developmental constraint that strongly affected the evolution of tanystropheids. The data obtained just at the base of the archosauromorph phylogenetic tree is crucial for further studies on the modularity of vertebral columns of not only Triassic reptile groups but extant and other extinct animals as well.</p>

AlloyManufacturingNet for discovery and design of hardness-elongation synergy in multi-principal element alloys
<p>Description</p> <p>1. Models saved after training the neural networks:</p> <p>a. hardness_saved_models.zip</p> <p>b. ductility_saved_models.zip</p> <p>2.<strong> prediction_data_for_casting_process.zip</strong>: Alloy types and their composition variants are provided in the file <strong>multicomponent_alloys_variants_compositions.csv</strong>. The hardness prediction for casting process with alloys are given in <strong>hardness_prediction_alloys_CAT-A.csv</strong> file whereas elongation prediction for the alloys for the same process (manufacturing route) are provided in<strong> elongation_prediction_alloys_CAT-A.csv</strong>. The composition sets D1_{x}D2_{y}(ZrHfNb)_{1-x-y} are referred to as<strong> Alloy A</strong>, whereas D1_{x}D2_{y}(VNbTa)_{1-x-y} are denoted as <strong>Alloy B</strong> in the columns of the csv files. The numeric value after alloy type denotes the specific pairs of the dopants [D1,D2] . For example, the alloy variants Ti_{x}Ta_{y}(ZrHfNb)_{1-x-y}, W_{x}Ta_{y}(ZrHfNb)_{1-x-y}, Mo_{x}Ta_{y}(ZrHfNb)_{1-x-y}, and Cr_{x}W_{y}(ZrHfNb)_{1-x-y} are referred to as Alloy A1, Alloy A2, Alloy A3 and Alloy A4 respectively. Similarly, Alloy A1, Alloy A2, Alloy A3 and Alloy A4 respectively denote Cr_{x}W_{y}(VNbTa)_{1-x-y}, Zr_{x}W_{y}(VNbTa)_{1-x-y}, Hf_{x}W_{y}(VNbTa)_{1-x-y}, and Mo_{x}Ti_{y}(VNbTa)_{1-x-y}. Hence, if a column is represented as HV_A2, then it is the hardness prediction for the alloy systems W_{x}Ta_{y}(ZrHfNb)_{1-x-y}, and if the column header is EL_B3, then the elongation of Hf_{x}W_{y}(VNbTa)_{1-x-y} alloy systems is estimated.</p>
Pistil length and width, pollen diameter, pollen tube elongations, fruitset, seedset and germination rates in european invasive populations of Ludwigia grandiflora subsp. hexapetala in the two floral morphs
<p>Mating system influences local population genetic structure, effective size, offspring fitness and functional variation. Determining the respective importance of self- and cross-fertilization in hermaphroditic flowering plants is thus important to understand their ecology and evolution. The worldwide invasive species, <em>Ludwigia </em><em>grandiflora</em> subsp. <em>hexapetala </em>(<em>Lgh</em>) presents two floral morphs: one self-compatible short-styled morph (S-morph) and one self-incompatible long-styled morph (L-morph). Most invasive populations worldwide are only composed of self-incompatible L-morphs, which questions the importance of sexual reproduction during the invasion. In this study, we identified the mating systems of western European experimental and natural populations of <em>Lgh </em>by comparing structural characteristics of pollen and style, by studying self- and cross-pollen tube elongations and the viability of the resulting seeds and seedlings in both morphs. The dataset provides measures of pistil length and width; pollen diameter; pollen tube elongations along time after pollination; fruitset, seedset and germination rate in in situ monomorphic L-morph and S-morph populations of western europe invasive <em>Lgh</em>. These data support the manuscript "Late-acting self-incompatible system, preferential allogamy and delayed selfing in the heterostylous invasive populations of <em>Ludwigia grandiflora</em> subsp. <em>hexapetala</em>" by Luis O. Portillo Lemus, Marilyne Harang, Michel Bozec, Jacques Haury, Solenn Stoeckel and Dominique Barloy arguing for a mixed mating system in a European invasive populations of <em>Ludwigia grandiflora</em> subsp. <em>hexapetala.</em></p> <p> </p> <p> </p>
