Data from: A stable phylogenomic classification of Travunioidea (Arachnida, Opiliones, Laniatores) based on sequence capture of ultraconserved elementsShahan Derkarabetian, James Starrett, Nobuo Tsurusaki, Darrell Ubick, Stephanie Castillo & Marshal Hedin
Molecular phylogenetics has transitioned into the phylogenomic era, with data derived from next-generation sequencing technologies allowing unprecedented phylogenetic resolution in all animal groups, including understudied invertebrate taxa. Within the most diverse harvestmen suborder, Laniatores, most relationships at all taxonomic levels have yet to be explored from a phylogenomics perspective. Travunioidea is an early-diverging lineage of laniatorean harvestmen with a Laurasian distribution, with species distributed in eastern Asia, eastern and western North America, and south-central Europe....
Data from: Taxonomic revision of the Malagasy Camponotus subgenus Mayria (Hymenoptera, Formicidae) using qualitative and quantitative morphologyJean Claude Rakotonirina & Brian L. Fisher
The Camponotus subgenus Mayria is revised based on the analysis of both qualitative morphological characters and morphometric traits. The multivariate analysis combined the Nest Centroid (NC)-clustering method and Partitioning Algorithm based on Recursive Thresholding (PART) function to generate species hypotheses based on 19 continuous morphological traits of minor workers. The proposed species hypotheses were confirmed by cumulative Linear Discriminant Analysis (LDA). Morphometric ratios for the subsets of minor and major workers were used in species...
Background: Echinoidea is a clade of marine animals including sea urchins, heart urchins, sand dollars and sea biscuits. Found in benthic habitats across all latitudes, echinoids are key components of marine communities such as coral reefs and kelp forests. A little over 1,000 species inhabit the oceans today, a diversity that traces its roots back at least to the Permian. Although much effort has been devoted to elucidating the echinoid tree of life using a...
Data from: Quantifying the dark data in museum fossil collections as palaeontology undergoes a second digital revolutionCharles R. Marshall, Seth Finnegan, Erica C. Clites, Patricia A. Holroyd, Nicole Bonuso, Crystal Cortez, Edward Davis, Gregory P. Dietl, Patrick S. Druckenmiller, Ron C. Eng, Christine Garcia, Kathryn Estes-Smargiassi, Austin Hendy, Kathy A. Hollis, Holly Little, Elizabeth A. Nesbitt, Peter Roopnarine, Leslie Skibinski, Jann Vendetti & Lisa D. White
Large-scale analysis of the fossil record requires aggregation of palaeontological data from individual fossil localities. Prior to computers these synoptic datasets were compiled by hand, a laborious undertaking that took years of effort and forced palaeontologists to make difficult choices about what types of data to tabulate. The advent of desktop computers ushered in palaeontology’s first digital revolution – online literature-based databases, such as the Paleobiology Database (PBDB). However, the published literature represents only a...
Mites (Acari) are one of the most diverse groups of life on Earth, yet their evolutionary relationships are poorly understood. Also, the resolution of broader arachnid phylogeny has been hindered by an underrepresentation of mite diversity in phylogenomic analyses. To further our understanding of Acari evolution,we design targeted ultraconserved genomic elements (UCEs) probes, intended for resolving the complex relationships between mite lineages and closely related arachnids. We then test our Acari UCE baits in-silico by...
Data from: Paleotropical diversification dominates the evolution of the hyperdiverse ant tribe Crematogastrini (Hymenoptera: Formicidae)Bonnie B. Blaimer, Philip S. Ward, Ted R. Schultz, Brian L. Fisher & Seán G. Brady
Levels of diversity vary strikingly among different phylogenetic lineages of ants. Rapid radiations in early ant evolution have often proven difficult to resolve with traditional Sanger-sequencing data sets of modest size. We provide a phylogenomic perspective on the evolution of the hyperdiverse ant tribe Crematogastrini by analyzing sequence data for nearly 1800 ultraconserved element (UCE) loci from 153 species comprising 56 genera. We reconstruct a next-to-complete genus-level phylogeny using concatenated maximum-likelihood and species-tree approaches, estimate...
Data from: Adaptation to reef habitats through selection on the coral animal and its associated microbiomeMadeleine J.H. Van Oppen, Pim Bongaerts, Pedro Frade, Lesa M. Peplow, Sarah E. Boyd, Hieu T. Nim, Line K. Bay & Madeleine J. H. Van Oppen
Spatially adjacent habitats on coral reefs can represent highly distinct environments, often harbouring different coral communities. Yet, certain coral species thrive across divergent environments. It is unknown whether the forces of selection are sufficiently strong to overcome the counteracting effects of the typically high gene flow over short distances, and for local adaptation to occur. We screened the coral genome (using restriction-site-associated sequencing [RAD-seq]), and characterized both the dinoflagellate photosymbiont and tissue-associated prokaryote microbiomes (using...
Coral reefs are increasingly threatened by thermal bleaching and tropical storm events associated with rising sea surface temperatures. Deeper habitats offer some protection from these impacts and may safeguard reef-coral biodiversity, but their faunas are largely undescribed for the Indo-Pacific. Here, we show high species richness of scleractinian corals in mesophotic habitats (30-125 m) for the northern Great Barrier Reef region that greatly exceeds previous records for mesophotic habitats globally. Overall, 45% of shallow reef...
Data from: Scaling up DNA barcoding - primer sets for simple and cost efficient arthropod systematics by multiplex PCR and Illumina amplicon sequencingHenrik Krehenwinkel, Susan R. Kennedy, Alexandra Rueda, Athena Lam & Rosemary G. Gillespie
1. The simplicity and cost efficiency of Illumina amplicon sequencing has greatly contributed to the advancement of DNA barcoding and metabarcoding applications. However, current amplicon sequencing based barcoding approaches are usually restricted to short, single-locus fragments, limiting their taxonomic and phylogenetic resolution. 2. Here, we establish a cost efficient and simple multiplex PCR protocol for arthropod systematics by Illumina amplicon sequencing. We introduce primer sets, including several new, generic primers, to reliably amplify nine loci...
Data from: Cryptic speciation yields remarkable mimics: A new genus of sea slugs that masquerade as toxic algae (Caulerpa spp.)Patrick J. Krug, Nur Leena W.S. Wong, Melanie R. Medina, Terrence M. Gosliner, Angel A. Valdes & Nur Leena W. S. Wong
“Cryptic” can refer to species that match their background through camouflage or disruptive coloration, or in taxonomy to externally similar but unrecognized congeners. In adaptive resemblance, organisms resemble parts of a larger host animal or plant on which the mimic is highly cryptic. Mimetic lineages that radiate onto superficially similar hosts may contain cryptic species in both senses: taxa that are difficult to detect, and challenging for taxonomists to distinguish. Here, we describe a new...
