Data from: Anchored hybrid enrichment provides new insights into the phylogeny and evolution of longhorned beetles (Cerambycidae)

Stephanie Haddad, Seunggwan Shin, Alan R. Lemmon, Emily Moriarty Lemmon, Petr Svacha, Brian Farrell, Adam Ślipiński, Donald Windsor & Duane D. McKenna
Cerambycidae is a species-rich family of mostly wood-feeding (xylophagous) beetles containing nearly 35 000 known species. The higher-level phylogeny of Cerambycidae has never been robustly reconstructed using molecular phylogenetic data or a comprehensive sample of higher taxa, and its internal relationships and evolutionary history remain the subjects of ongoing debate. We reconstructed the higher-level phylogeny of Cerambycidae using phylogenomic data from 522 single copy nuclear genes, generated via anchored hybrid enrichment. Our taxon sample (31...

Phylogenomic data for hyperdiverse daisy tribes

Jennifer Mandel, Linda Watson & Carolina Siniscalchi
Asteraceae account for 10% of all flowering plant species, and 35-40% of these are in five closely-related tribes that total over 10,000 species. These tribes include Anthemideae, Astereae, Calenduleae, Gnaphalieae, and Senecioneae, which form one of two enormous clades within Subfamily Asteroideae. We took a phylogenomics approach to resolve evolutionary relationships among these five tribes. We sampled the nuclear and plastid genomes via HybSeq target enrichment and genome skimming, and recovered 74 plastid genes and...

Data from: Distribution and biogeography of Sanguina snow algae: fine-scale sequence analyses reveal previously unknown population structure

Shawn Brown
It has been previously suggested that snow algal species within the genus Sanguina (S. nivaloides and S. aurantia) show no population structure despite being found globally (S. nivaloides) or throughout the Northern Hemisphere (S. aurantia). However, systematic biogeographic research into global distributions is lacking due to few genetic and no genomic resources for these snow algae. Here, using all publicly available and previously unpublished Sanguina sequences of the Internal Transcribed Spacer 2 region, we investigate...

Phylogenomic analysis sheds light on the evolutionary pathways towards acoustic communication in Orthoptera

Hojun Song, Olivier Béthoux, Seunggwan Shin, Alexander Donath, Harald Letsch, Shanlin Liu, Duane D. McKenna, Guanliang Meng, Bernhard Misof, Lars Podsiadlowski, Xin Zhou, Benjamin Wipfler & Sabrina Simon
Acoustic communication is enabled by the evolution of specialised hearing and sound producing organs. In this study, we performed a large-scale macroevolutionary study to understand how both hearing and sound production evolved and affected diversification in the insect order Orthoptera, which includes many familiar singing insects, such as crickets, katydids, and grasshoppers. Using phylogenomic data, we firmly establish phylogenetic relationships among the major lineages and divergence time estimates within Orthoptera, as well as the lineage-specific...

Data from: The genetic basis of speciation in the Giliopsis lineage of Ipomopsis (Polemoniaceae)

Troy E. Wood, Takuya Nakazato & Loren H. Rieseberg
One of the most powerful drivers of speciation in plants is pollinator-mediated disruptive selection, which leads to the divergence of floral traits adapted to the morphology and behavior of different pollinators. Despite the widespread importance of this speciation mechanism, its genetic basis has been explored in only a few groups. Here, we characterize the genetic basis of pollinator-mediated divergence of two species in genus Ipomopsis, I. guttata and I. tenuifolia, using quantitative trait locus (QTL)...

Data from: An empirical assessment of a single family-wide hybrid capture locus set at multiple evolutionary timescales in Asteraceae

Katy E Jones, Tomáš Fér, Roswitha E Schmickl, Rebecca B Dikow, Vicki A Funk, Sonia Herrando-Moraira, Norbert Kilian, Carolina M Siniscalchi, Alfonso Susanna, Marek Slovák, Ramhari Thapa, Linda E Watson & Jennifer R Mandel
Premise of the study: Hybrid capture with high-throughput sequencing (Hyb-Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family-specific Hyb-Seq method and the outcomes of different phylogenetic analyses are assessed. Methods: Hyb-Seq data from 112 Asteraceae samples were organized into groups at different taxonomic levels (tribe, genus, and species). For each group, datasets of non-paralogous loci were built and proportions of parsimony informative characters estimated. The impacts of the analyzing alternative...

Data from: Genomic and morphological evidence converge to resolve the enigma of Strepsiptera

Oliver Niehuis, Gerrit Hartig, Sonja Grath, Hans Pohl, Jörg Lehmann, Hakim Tafer, Alexander Donath, Veiko Krauss, Carina Eisenhardt, Jana Hertel, Malte Petersen, Christoph Mayer, Karen Meusemann, Ralph S. Peters, Peter F. Stadler, Rolf G. Beutel, Erich Bornberg-Bauer, Duane D. McKenna & Bernhard Misof
The phylogeny of insects, one of the most spectacular radiations of life on earth, has received considerable attention. However, the evolutionary roots of one intriguing group of insects, the twisted-wing parasites (Strepsiptera), remain unclear despite centuries of study and debate. Strepsiptera exhibit exceptional larval developmental features, consistent with a predicted step from direct (hemimetabolous) larval development to complete metamorphosis that could have set the stage for the spectacular radiation of metamorphic (holometabolous) insects. Here we...

Data from: A protocol for targeted enrichment of intron-containing sequence markers for recent radiations: a phylogenomic example from Heuchera (Saxifragaceae)

Ryan A. Folk, Jennifer R. Mandel & John V. Freudenstein
Premise of the study: Phylogenetic inference is moving to large multilocus data sets, yet there remains uncertainty in the choice of marker and sequencing method at low taxonomic levels. To address this gap, we present a method for enriching long loci spanning intron-exon boundaries in the genus Heuchera. Methods: Two hundred seventy-eight loci were designed using a splice-site prediction method combining transcriptomic and genomic data. Biotinylated probes were designed for enrichment of these loci. Reference-based...

Phylogenomics resolves the relationships within Antennaria (Asteraceae, Gnaphalieae) and yields new insights into its morphological character evolution and biogeography

Ramhari Thapa, Randall Bayer & Jennifer Mandel
Antennaria are dioecious perennial herbs distributed mainly in the Holarctic Region with their major center of diversity in the Rocky Mountains of Western North America. The genus comprises 33 known sexual diploid/tetraploid species and at least five polyploid agamic complexes which mostly reproduce by forming asexual seeds. We performed a phylogenetic reconstruction of the 31 sexually-reproducing Antennaria species using a novel target enrichment method that employs custom capture probes and is designed to work across...

Data from: Phylogenomics resolves the timing and pattern of insect evolution

Bernhard Misof, Shanlin Liu, Karen Meusemann, Ralph S. Peters, Alexander Donath, Christoph Mayer, Paul B. Frandsen, Jessica Ware, Tomas Flouri, Rolf G. Beutel, Oliver Niehuis, Malte Petersen, Fernando Izquierdo-Carrasco, Torsten Wappler, Jes Rust, Andre J. Aberer, Ulrike Aspöck, Horst Aspöck, Daniela Bartel, Alexander Blanke, Simon Berger, Alexander Böhm, Thomas Buckley, Brett Calcott, Junqing Chen … & Xin Zhou
Insects are the most speciose group of animals, but the phylogenetic relationships of many major lineages remain unresolved. We inferred the phylogeny of insects from 1478 protein-coding genes. Phylogenomic analyses of nucleotide and amino acid sequences, with site-specific nucleotide or domain-specific amino acid substitution models, produced statistically robust and congruent results resolving previously controversial phylogenetic relations hips. We dated the origin of insects to the Early Ordovician [~479 million years ago (Ma)], of insect flight...

Data from: Let's stick together: infection enhances preferences for social settings in a songbird species

Marissa Langager, James Adelman & Dana Hawley
Acute infections can alter foraging and movement behaviours relevant to sociality and pathogen spread. However, few studies have examined how infection with directly-transmitted pathogens influences host social preferences. Juvenile house finches are gregarious and particularly susceptible to infection by the bacterial pathogen Mycoplasma gallisepticum (MG). Changes in sociality during infection are likely to have important consequences for MG transmission throughout majority-juvenile flocks, but it remains unknown how infection influences sociality in house finches. To test...

Data From: Phylogenomics reveals accelerated late Cretaceous diversification of bee flies (Diptera: Bombyliidae)

Xuankun Li, Luisa C. Teasdale, Keith M. Bayless, Allan G. Ellis, Brian M. Wiegmann, Carlos José E. Lamas, Christine L. Lambkin, Neal L. Evenhuis, James A. Nicholls, Diana Hartley, Seunggwan Shin, Michelle Trautwein, Andreas Zwick, Bryan D. Lessard & David K. Yeates
Bombyliidae is a very species-rich and widespread family of parasitoid flies with more than 250 genera classified into 17 extant subfamilies. However, little is known about their evolutionary history or how their present-day diversity was shaped. Transcriptomes of 15 species and anchored hybrid enrichment (AHE) sequence captures of 86 species, representing 94 bee fly species and 14 subfamilies, were used to reconstruct the phylogeny of Bombyliidae. We integrated data from transcriptomes across each of the...

Historical biogeography of New World Passalidae

Cristian Beza-Beza, Larry Jiménez-Ferbans & Duane McKenna
Aim: The fauna of Mesoamerica is extraordinarily species rich and exhibits a high degree of local, regional, and high-elevation endemism. Traditionally, this area has been seen as a transition zone between the Nearctic and Neotropical regions; in contrast, new data suggest Mesoamerica is a center of origin and taxonomic diversification. For example, the diversity of species and genera of Passalidae in Mesoamerica is concentrated in montane environments and there are many locally-endemic taxa; thus, Mesoamerica...

Data from: Using phylogenomics to resolve mega-families: an example from Compositae

Jennifer R. Mandel, Rebecca B. Dikow & Vicki A. Funk
Next-generation sequencing and phylogenomics hold great promise for elucidating complex relationships among large plant families. Here we performed targeted capture of low copy sequences followed by next-generation sequencing on the Illumina platform in the large and diverse angiosperm family Compositae (Asteraceae). The family is monophyletic based on morphology and molecular data, yet many areas of the phylogeny have unresolved polytomies and interpreting phylogenetic patterns has been historically difficult. In order to outline a method and...

Data from: Phylogenomics clarifies repeated evolutionary origins of inbreeding and fungus farming in bark beetles (Curculionidae, Scolytinae)

Andrew Johnson, McKenna, Bjarte H. Jordal, Anthony I. Cognato, Sarah M. Smith, Alan R. Lemmon, Emily L. Moriarty Lemmon & Jiri Hulcr
Bark and ambrosia beetles (Curculionidae, Scolytinae) display a conspicuous diversity of unusual genetic and ecological attributes and behaviors. Reconstructing the evolution of Scolytinae, particularly the large and ecologically significant tribe Cryphalini (pygmy borers), has long been problematic. These challenges have not adequately been addressed using morphological characters, and previous research has used only DNA sequence data from small numbers of genes. Through a combination of anchored hybrid enrichment, low-coverage draft genomes, and transcriptomes, we addressed...

Data from: Pre- and post-natal effects of experimentally manipulated maternal corticosterone on growth, stress reactivity, and survival of nestling house wrens

Beth M. Weber, E. Keith Bowers, Kimberly A. Terrell, Josephine F. Falcone, Charles F. Thompson & Scott K. Sakaluk
1. Corticosterone plays a central role in maintaining homeostasis, promoting energy acquisition, and regulating the stress response in birds. Exposure to elevated levels of corticosterone during development can profoundly alter offspring behaviour and physiology, but the effects of elevated maternal corticosterone on offspring development remain poorly understood. 2. We tested two competing hypotheses concerning the effect of maternally derived corticosterone on growth and development of free-living house wrens: i) elevated maternal corticosterone causes damaging effects...

Data from: Epigenome-wide association study of lung function level and its change

Medea Imboden, Matthias Wielscher, Faisal I Rezwan, Andre F S Amaral, Emmanuel Schaffner, Ayoung Jeong, Anna Beckmeyer-Borowko, Sarah E Harris, John M Starr, Ian J Deary, Claudia Flexeder, Melanie Waldenberger, Annette Peters, Holger Schulz, Su Chen, Shadia KHan Sunny, Wilfried J J Karmaus, Yu Jiang, Gertraud Erhart, Florian Kronenberg, Ryan Arathimos, Gemma C Sharp, Alexander John Henderson, Yu Fu, Paivi Piirila … & Nicole M Probst-Hensch
Previous reports link differential DNA methylation (DNAme) to environmental exposures which are associated with lung function. Direct evidence on lung function DNAme is however limited. We undertook an agnostic epigenome-wide association study (EWAS) on pre-bronchodilation lung function and its change in adults. In a discovery-replication EWAS design, DNAme in blood and spirometry were measured twice, six-to-15 years apart, in the same participants of three adult population-based discovery cohorts (n=2,043). Associated DNAme markers (P<5x10-7) were tested...

Data from: Climate and host plant associations shaped the evolution of ceutorhynch weevils throughout the Cenozoic

Harald Letsch, Brigitte Gottsberger, Christian Metzl, Jonas Astrin, Ariel Leib Leonid Friedman, Duane D. McKenna & Konrad Fiedler
Using molecular phylogenetic data and methods we infer divergence times and diversification patterns for the weevil subfamily Ceutorhynchinae in the context of host-plant associations and global climate over evolutionary time. We detected four major diversification shifts that correlate with both host shifts and major climate events. Ceutorhynchinae experienced an increase in diversification rate at ~53 Ma, during the Early Eocene Climate Optimum, coincident with a host shift to Lamiaceae. A second major diversification phase occurred...

Data from: Resource constraints highlight complex microbial interactions during lake biofilm development

Kevin H. Wyatt, Rody C. Seballos, Maria N. Shoemaker, Shawn P. Brown, Sudeep Chandra, Kevin A. Kuehn, Allison R. Rober & Steven Sadro
Abstract 1. This study evaluated how the availability of nutrients and organic carbon interact to influence the associations between autotrophic and heterotrophic microorganisms during lake biofilm development. Considering that decomposers are often better competitors for nutrients than producers in aquatic environments, we hypothesized that heterotrophs would outcompete autotrophs for available nutrients unless heterotrophs were limited by organic carbon provided by autotrophs. 2. To test our hypothesis, we evaluated autotrophic (algae) and heterotrophic (fungi, bacteria) biomass...

Male meadow vole scent marking 1 rival odor context

Ryan Scauzillo
Meadow voles (Microtus pennsylvanicus) rely on olfactory communication, such as scent marking, to find and secure mating opportunities during the breeding season. Scent marks, and odors in general, provide information about the donors and persists in the environment for extended periods, allowing a wide audience. Whether a vole responds to another scent mark(s), or odor(s), depends on the social context and the information the odor provides about the donor(s). Therefore, we examined if male scent...

Variation in brown rat cranial shape shows directional selection over 120 years in New York City

Emily Puckett, Emma Sherratt, Matthew Combs, Elizabeth Carlen, William Harcourt-Smith & Jason Munshi-South
Urbanization exposes species to novel environments and selection pressures that may change morphological traits within a population. We investigated how the shape and size of crania and mandibles changed over time within a population of brown rats (Rattus norvegicus) living in Manhattan, New York, USA, a highly urbanized environment. We measured 3D landmarks on the cranium and mandible of 62 adult individuals sampled in the 1890s and 2010s. Static allometry explained approximately 22% of shape...

Bergmann's rule is followed at multiple stages of post-embryonic development in a long-distance migratory songbird

Joseph Youtz, Kelly Miller, Emerson Bowers, Samantha Rogers, Lesley Bulluck, Matthew Johnson, Brian Peer, Katie Percy, Erik Johnson, Elizabeth Ames, Christopher Tonra & Than Boves
Aim: We assessed the presence of Bergmann’s rule in a model migratory species across all life stages on their breeding grounds. We then compared historic and contemporary egg sizes to understand if the biogeographic patterns during this developmental life stage have changed over time. Location: Eastern North America. Time period: 1865 to 2019. Major taxa: Prothonotary warbler, Protonotaria citrea Methods: We measured the size of eggs, young and old nestlings, and adults (of two age...

Data from: On the rupture propagation of the 2019 M6.4 Searles Valley Earthquake, and the lack of immediate triggering of the M7.1 Ridgecrest Earthquake

Jordan Cortez, David Oglesby, Christodoulos Kyriakopoulos, Baoning Wu, Kuntal Chaudhuri, Abhijit Ghosh & Roby Douilly
The 2019 M6.4 Searles Valley, Southern California, earthquake nucleated on a buried right-lateral fault segment and propagated around a perpendicular fault intersection to a surface-outcropping left-lateral segment, but it did not propagate coseismically to the intersecting fault of the subsequent M7.1 Ridgecrest mainshock. We use the 3D finite element method to explore the physical reasons for this curious rupture path. Rather than model the details of the measured and inferred slip distribution, we use simple...

Data from: The first phylogeny of Australasian Lamiinae longhorn beetles

Lauren Ashman, Seunggwan Shin, Andreas Zwick, Adam Slipinski & Duane McKenna
We used phylogenomic data and information from the beetle fossil record to reconstruct the phylogeny and historical biogeography of Australasian longhorn beetles (Cerambycidae) in the subfamily Lamiinae. We further focused our study on the distribution of proposed diagnostic morphological characters in Lamiinae, and on the phylogeny of Rhytiphora Audinet-Serville, Australia’s most species-rich genus of longhorn beetles. Lamiinae was monophyletic, but the majority of tribes were poly- or paraphyletic. Within Lamiinae, we recovered four main clades,...

Data from: Anthelmintic drugs modulate the acute phase immune response but not the microbiota in wild Song Sparrows

Grace Vaziri, Michelle Jusino, Jon Palmer, Matthew Brewer & James Adelman
Co-infection with microparasites (e.g., bacteria) and macroparasites (e.g., helminths) is often the natural state for wild animals. Despite evidence that gut helminths can bias immune responses away from inflammatory processes, few field studies have examined the role that helminths, or their potential interactions with internal microbial communities, play in modulating immunity in free-living, wild birds. Here, we used anthelmintic drugs to treat wild Song Sparrows (Melospiza melodia) for helminth infections and measured markers of systemic...
