The German Barcoding initiatives BFB and GBOL have generated a reference library of more than 16,000 metazoan species, which is now ready for applications concerning next generation molecular biodiversity assessments. To streamline the barcoding process, we developed meta-barcoding pipeline: We pre-sorted single malaise trap sample (obtained during one week in August 2014, southern Germany) into 12 arthropod orders extracted DNA from pooled individuals each order separately, to facilitate...
Abstract Most cellular ubiquitin signaling is initiated by UBA1, which activates and transfers to tens of E2 enzymes. Clonally acquired UBA1 missense mutations cause an inflammatory-hematologic overlap disease called VEXAS (vacuoles, E1, X-linked, autoinflammatory, somatic) syndrome. Despite extensive clinical investigation into this lethal disease, little known about the underlying molecular mechanisms. Here, dissecting VEXAS-causing mutations, we discovered that p.Met41 alter cytoplasmic...
Weevils (Curculionoidea) comprise one of the most diverse groups organisms on earth. There is hardly a vascular plant or part without its own species weevil feeding it and diversity greater than number fishes, birds, reptiles, amphibians mammals combined. Here, we employ ultraconserved elements (UCEs) designed for beetles novel partitioning strategy loci to help resolve phylogenetic relationships within radiation Australasian smurf-weevils (Eupholini). Despite being emblematic New Guinea...
Abstract Tetraopes longhorn beetles are known for their resistance to milkweed plant toxins and coevolutionary dynamics with plants ( Asclepias ). This association is considered a textbook example of coevolution, in which each species specialized feed on one or few . A major challenge investigating hypotheses conducting molecular ecology studies lies the limited understanding evolutionary history biogeographical patterns By integrating genomic, morphological, paleontological, geographical...

Among vertebrates, turtles have many unique characteristics providing biologists with opportunities to study novel evolutionary innovations and processes. We present here a high-quality, partially phased, chromosome-level Red-Eared Slider (Trachemys scripta elegans, TSE) genome as reference for future research on turtle tetrapod evolution. This TSE assembly is 2.269 Gb in length, has one of the highest scaffold N50 N90 values any published date (N50 = 129.68 Mb 19 Mb), total 28,415 annotated...
The genus Cyriotasiastes (Neman, 1842) is revised using a combination of morphological, biogeographic, and molecular data. Based on this, we proposed to erect the four species belonging sub-species rhetenor: C.rhetenor rhetenor, C. rhetenor mindorensis, panayensis, solsonanensis, as separate with following statuses: (Newman, stat. nov., solsonanensis Medina et al., 2023 mindorensis Vives, 2009 C.s panayensis Barševskis, 2018 nov. A new Cyiotasiastes mindanaonis sp. also described, this first...
Abstract The simplicity and cost efficiency of Illumina amplicon sequencing has greatly contributed to the advancement DNA barcoding metabarcoding applications. However, current sequencing‐based approaches are usually restricted short, single‐locus fragments, limiting their taxonomic phylogenetic resolution. Here, we establish a efficient simple multiplex PCR protocol for arthropod systematics by sequencing. We introduce primer sets, including several new, generic primers, reliably amplify...
Abstract Background The New Guinean archipelago has been shaped by millions of years plate tectonic activity combined with long-term fluctuations in climate and sea level. These processes Guinea’s location at the junction between Australian Pacific plates are inherently linked to evolution its rich endemic biota. With advent molecular phylogenetics an increasing amount geological data, field biogeography begins be reinvigorated. Results We inferred a comprehensive dated phylogeny diving...
Patterns of genomic architecture across insects remain largely undocumented or decoupled from a broader phylogenetic context. For instance, it is unknown whether translocation rates differ between insect orders. We address broad scale patterns genome Insecta by examining synteny in framework open-source genomes. To accomplish this, we add chromosome level to crucial lineage, Coleoptera. Our assembly the Pachyrhynchus sulphureomaculatus first for hyperdiverse Phytophaga lineage and currently...
Abstract Aim We studied the gecko genus Ebenavia to reconstruct its colonization history, test for anthropogenic versus natural dispersal out of Madagascar, and correlate divergence date estimates our phylogeny with geological age islands in region. Location Madagascar surrounding Western Indian Ocean (Comoros, Mayotte, Mauritius, Pemba). Methods reconstructed covering entire geographical range using a molecular data set three mitochondrial two nuclear markers. estimated times based on...
Past geological and climatological processes shape extant biodiversity. In the Hawaiian Islands, these have provided physical environment for a number of extensive adaptive radiations. Yet, single species that occur throughout islands provide some best cases understanding how respond to shifting dynamics in context colonization history associated demographic shifts. Here, we focus on happy-face spider, color-polymorphic species, use mitochondrial nuclear allozyme markers examine (1) mosaic...
Our understanding of the origin and evolution astonishing Neotropical biodiversity remains somewhat limited. In particular, decoupling respective impacts biotic abiotic factors on macroevolution clades is paramount to understand assemblage in this region. We present first comprehensive molecular phylogeny for Anaeini leafwing butterflies (Nymphalidae, Charaxinae) and, applying likelihood-based methods, we test impact major (Andean orogeny, Central American highland Proto-Caribbean seaway...
Genetically controlled colour polymorphisms provide a physical manifestation of the operation selection and how this can vary according to spatial or temporal arrangement phenotypes, their frequency in population. Here, we examine role shaping exuberant polymorphism exhibited by spider Theridion californicum. This species is part system which several distantly related spiders same lineage, but living very different geographical areas, exhibit remarkably convergent polymorphisms. These are...
Abstract The evolutionary origins of mimicry in the Easter egg weevil, Pachyrhynchus, have fascinated researchers since first noted more than a century ago by Alfred Russel Wallace. Müllerian mimicry, or which 2 distasteful species look similar, is widespread throughout animal kingdom. Given varied but discrete color patterns this genus presents one best opportunities to study evolution both perfect and imperfect mimicry. We analyzed 10,000 UCE loci using novel partitioning strategy resolve...
Abstract Spatial and environmental heterogeneity are major factors in structuring species distributions alpine landscapes. These landscapes have also been affected by glacial advances retreats, causing taxa to undergo range shifts demographic changes. nonequilibrium population dynamics the potential obscure effects of on distribution genetic variation.

Phylogenomics via ultraconserved elements (UCEs) has led to improved phylogenetic reconstructions across the tree of life. However, inadvertently incorporating non-targeted DNA into UCE marker design will lead misinformation being incorporated subsequent analyses. To date, effectiveness basic metagenomic filtering strategies not been assessed in arthropods. Designing markers from museum specimens requires careful consideration methods due high levels microbial contamination typically found...
The habitat template concept applied to a freshwater system indicates that lotic species, or those which occupy permanent habitats along stream courses, are less dispersive than lentic occur in more ephemeral aquatic habitats. Thus, populations of species will be structured species. Stream courses include both flowing water and small, stagnant microhabitats can provide refuge when streams low. Many these but remain poorly studied. Here, we present population genetic data for one such the...
