Phase resolution of heterozygous sites in diploid genomes is important to phylogenomic analysis under the multispecies coalescent model

Ziheng Yang, Jun Huang, Tomas Flouri, Jeremy Bennett & Adam Leache
Genome sequencing projects routinely generate haploid consensus sequences from diploid genomes, which are effectively chimeric sequences with the phase at heterozygous sites resolved at random. The impact of phasing errors on phylogenomic analyses under the multispecies coalescent (MSC) model is largely unknown. Here we conduct a computer simulation to evaluate the performance of four phase-resolution strategies (the true phase resolution, the diploid analytical integration algorithm which averages over all phase resolutions, computational phase resolution using...

Coexistence of predators in time: effects of season and prey availability on species activity within a Mediterranean carnivore guild

Marc Vilella, Mariona Ferrandiz-Rovira & Ferran Sayol
1. The degree of coexistence among predators can determine the structure of ecological communities. Niche partitioning is a common strategy applied by species to enhance their coexistence. Diet, habitat or time use can be responsible for segregation among carnivore species, the latter factor being the least studied in Mediterranean ecosystems. Terrestrial medium-sized carnivores (i.e. mesocarnivores) carry out important functions in ecosystems and identifying their interactions is essential for their conservation. 2. In this study, we...

The asymptotic behavior of bootstrap support values in molecular phylogenetics

Jun Huang, Yuting Liu, Tianqi Zhu & Ziheng Yang
The phylogenetic bootstrap is the most commonly used method for assessing statistical confidence in estimated phylogenies by non-Bayesian methods such as maximum parsimony and maximum likelihood (ML). It is observed that bootstrap support tends to be high in large genomic datasets whether or not the inferred trees and clades are correct. Here we study the asymptotic behavior of bootstrap support for the ML tree in large datasets when the competing phylogenetic trees are equally right...

Breaking a species barrier by enabling hybrid recombination

G. Ozan Bozdag, Jasmine Ono, Jai A. Denton, Emre Karakoc, Neil Hunter, Jun-Yi Leu & Duncan Greig
Hybrid sterility maintains reproductive isolation between species by preventing them from exchanging genetic material. Anti-recombination can contribute to hybrid sterility when different species’ chromosome sequences are too diverged to cross-over efficiently during hybrid meiosis, resulting in chromosome mis-segregation and aneuploidy. The genome sequences of the yeasts Saccharomyces cerevisiae and Saccharomyces paradoxus have diverged by about 12% and their hybrids are sexually sterile: nearly all of their gametes are aneuploid and inviable. Previous methods to increase...

Middle Eocene terrestrial paleoweathering and climate evolution in the midlatitude Bohai Bay Basin of Eastern China

Di Chen, Xiongqi Pang, Kun Zhang, Guoyong Liu, Fujie Jiang, Liang Li, Youwei Wang, Min Li & Yang Liu
The middle Eocene is a key time period for understanding Cenozoic cooling of the global climate. In eastern Asia, this time period was marked by deposition of extensive mudstones, shales and interbedded siltstones, especially in the midlatitude Bohai Bay Basin. Still, midlatitude terrestrial records of climate evolution during the middle Eocene are rare. Here, we analyze a continuous, high-resolution record of this period using samples of the shales in the fourth submember of the third...

Natural history, phenotypic spectrum, and discriminative features of multisystemic RFC1-disease

Andreas Traschütz, Andrea Cortese, Selina Reich, Natalia Dominik, Jennifer Faber, Heike Jacobi, Annette Hartmann, Dan Rujescu, Solveig Montaut, Andoni Echaniz-Laguna, Sevda Erer, Valerie Cornelia Schütz, Alexander Tarnutzer, Marc Sturm, Tobias Haack, Nadège Vaucamps-Diedhiou, Helene Puccio, Ludger Schöls, Thomas Klockgether, Bart P. Van De Warrenburg, Martin Paucar, Dagmar Timmann, Ralf-Dieter Hilgers, Jose Gazulla, Michael Strupp … & Matthis Synofzik
Objective: To delineate the full phenotypic spectrum, discriminative features, piloting longitudinal progression data, and sample size calculations of RFC1-repeat expansions, recently identified as causing cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS). Methods: Multimodal RFC1 repeat screening (PCR, southern blot, whole-exome/genome (WES/WGS)-based approaches) combined with cross-sectional and longitudinal deep-phenotyping in (i) cross-European cohort A (70 families) with ≥2 features of CANVAS and/or ataxia-with-chronic-cough (ACC); and (ii) Turkish cohort B (105 families) with unselected late-onset ataxia. Results:...

Borane Catalyzed Stereoselective C–H insertion, Cyclopropanation, and Ring-Opening Reactions - data

Ayan Dasgupta, Rasool Babaahmadi, Ben Slater, Brian F Yates, Alireza Ariafard & Rebecca L Melen
Lewis acidic boranes have been shown to be an effective metal-free catalyst for highly selective reactions of donor-acceptor diazo compounds to a range of substrates. The reactions of α-aryl α-diazoesters with nitrogen heterocycles indole or pyrrole selectively generates C3 and C2 C–H insertion products respectively in good to excellent yields even when using unprotected indoles. Alternatively, benzofuran, indene, and alkene substrates give exclusively cyclopropanated products with α-aryl α-diazoesters, whereas the reactions with furans leads to...

Higher sociability leads to lower reproductive success in female kangaroos

Alecia Carter, Clementine Menz, Best Emily, Natalie Freeman, Ross Dwyer, Simone Blomberg & Anne Goldizen
In social mammals, social integration is generally assumed to improve females’ reproductive success. Most species demonstrating this relationship exhibit complex forms of social bonds and interactions. However, female eastern grey kangaroos (Macropus giganteus) exhibit social preferences, yet do not appear to cooperate directly. It is unclear what the fitness consequences of sociability could be in species that do not exhibit obvious forms of cooperation. Using four years of life history, spatial, and social data from...

Evolution of the speech‐ready brain: The voice/jaw connection in the human motor cortex

Steven Brown, Ye Yuan & Michel Belyk
A prominent model of the origins of speech, known as the “frame/content” theory, posits that oscillatory lowering and raising of the jaw provided an evolutionary scaffold for the development of syllable structure in speech. Because such oscillations are non‐vocal in most non‐human primates, the evolution of speech required the addition of vocalization onto this scaffold in order to turn such jaw oscillations into vocalized syllables. In the present functional MRI study, we demonstrate overlapping somatotopic...

Data from: Ten more years of discovery: revisiting the quality of the sauropodomorph dinosaur fossil record

Daniel Cashmore, Philip Mannion, Paul Upchurch & Richard Butler
Spatiotemporal changes in fossil specimen completeness can bias our understanding of a group’s evolutionary history. The quality of the sauropodomorph fossil record was assessed a decade ago, but the number of valid species has since increased by 60%, and 17% of the taxa from that study have since undergone taxonomic revision. Here, we assess how 10 years of additional research has changed our outlook on the group’s fossil record. We quantified the completeness of all...

A total-evidence dated phylogeny of Echinoidea combining phylogenomic and paleontological data

Nicolás Mongiardino Koch & Jeffrey Thompson
Phylogenomic and paleontological data constitute complementary resources for unravelling the phylogenetic relationships and divergence times of lineages, yet few studies have attempted to fully integrate them. Several unique properties of echinoids (sea urchins) make them especially useful for such synthetizing approaches, including a remarkable fossil record that can be incorporated into explicit phylogenetic hypotheses. We revisit the phylogeny of crown group Echinoidea using a total-evidence dating approach that combines the largest phylogenomic dataset for the...

Data from: Feeding specialisation and longer generation time are associated with relatively larger brains in bees

Ferran Sayol, Miguel Á. Collado, Joan Garcia-Porta, Marc A. Seid, Jason Gibbs, Ainhoa Agorreta, Diego San Mauro, Ivo Raemakers, Daniel Sol & Ignasi Bartomeus
Despite their miniature brains, insects exhibit substantial variation in brain size. Although the functional significance of this variation is increasingly recognized, research on whether differences in insect brain sizes are mainly the result of constraints or selective pressures has hardly been performed. Here, we address this gap by combining prospective and retrospective phylogenetic-based analyses of brain size for a major insect group, bees (superfamily Apoidea). Using a brain dataset of 93 species from North America...

National bat monitoring programme roost counts dataset

Lea Dambly, Kate Jones, Katherine Boughey & Nick Isaac
Many long-term wildlife population monitoring programmes rely on citizen scientists for data collection. This can offer several benefits over traditional monitoring practices as it is a cost-effective, large-scale approach capable of providing long time series data and raising public environmental awareness. Whilst there is a debate about the quality of citizen science data, a standardised sampling design can allow citizen science data to be of a similar quality to those collected by professionals. However, many...

Drosophila-parasitoid interactions along an elevation gradient in an Australian rainforest, 2016

C.T. Jeffs, J.C.D. Terry, M. Higgie, A. Jandová, H. Konvičková, J.J. Brown, C-H. Lue, M. Schiffer, E.K. O’Brien, J. Bridle, J. Hrček & O.T. Lewis
The dataset contains records of Drosophila flies and associated parasitic wasps collected along two elevational (temperature) gradients from Australian rainforest site. The data is presented at the individual Drosophila pupae level. It describes patterns of parasitism levels from 14 sites and the structure of quantitative food webs at six sites. Also included are temperature records from each site.

Data from: Late Cretaceous bird from Madagascar reveals unique development of beaks

Patrick O'Connor, Alan Turner, Joseph Groenke, Ryan Felice, Raymond Rogers, David Krause & Lydia Rahantarisoa
Mesozoic birds display considerable diversity in size, flight adaptations and feather organization, but exhibit relatively conserved patterns of beak shape and development. Although Neornithine (that is, crown group) birds also exhibit constraint on facial development, they have comparatively diverse beak morphologies associated with a range of feeding and behavioural ecologies, in contrast to Mesozoic birds. Here we describe a crow-sized stem bird, Falcatakely forsterae gen. et sp. nov., from the Late Cretaceous epoch of Madagascar...

Data from: Increased dystrophin production with golodirsen in patients with Duchenne muscular dystrophy

Diane E. Frank, Frederick J. Schnell, Cody Akana, Saleh H. El-Husayni, Cody A. Desjardins, Jennifer Morgan, Jay S. Charleston, Valentina Sardone, Joana Domingos, George Dickson, Volker Straub, Michela Guglieri, Eugenio Mercuri, Laurent Servais & Francesco Muntoni
Objective To report safety, pharmacokinetics, exon 53 skipping, and dystrophin expression in golodirsen-treated patients with Duchenne muscular dystrophy (DMD) amenable to exon 53 skipping. Methods Part 1 was a randomized, double-blind, placebo-controlled, 12-week dose titration of once-weekly golodirsen; Part 2 is an ongoing, open-label evaluation. Safety and pharmacokinetics were primary and secondary objectives of Part 1. Primary biological outcome measures of part 2 were blinded exon skipping and dystrophin protein production on muscle biopsies (baseline,...

Data From: Analysing social media forums to discover potential causes of phasic shifts in cryptocurrency price series

Andrew Burnie, Emine Yilmaz & Tomaso Aste
The recent extreme volatility in cryptocurrency prices occurred in the setting of popular social media forums devoted to the discussion of cryptocurrencies. We develop a framework that discovers potential causes of phasic shifts in the price movement captured by social media discussions. This draws on principles developed in healthcare epidemiology where, similarly, only observational data are available. Such causes may have a major, one-off effect or recurring effects on the trend in the price series....

Data from: Anthropogenic extinctions conceal widespread evolution of flightlessness in birds

Ferran Sayol, Manuel J. Steinbauer, Tim M. Blackburn, Alexandre Antonelli & Søren Faurby
Human-driven extinctions can affect our understanding of evolution, through the nonrandom loss of certain types of species. Here, we explore how knowledge of a major evolutionary transition—the evolution of flightlessness in birds—is biased by anthropogenic extinctions. Adding data on 581 known anthropogenic extinctions to the extant avifauna increases the number of species by 5%, but quadruples the number of flightless species. The evolution of flightlessness in birds is a widespread phenomenon, occurring in more than...

Evolution and development at the origin of a phylum

Bradley Deline, Jeffery Thompson, Nicholas Smith, Samuel Zamora, Imran Rahman, Sarah Sheffield, William Ausich, Thomas Kammer & Colin Sumrall
Quantifying morphological evolution is key to determining the patterns and processes underlying the origin of phyla. We constructed a hierarchical morphological character matrix to characterize the radiation and establishment of echinoderm body plans during the early Paleozoic. This showed that subphylum-level clades diverged gradually through the Cambrian, and the distinctiveness of the resulting body plans was amplified by the extinction of transitional forms and obscured by convergent evolution during the Ordovician. Higher-order characters that define...

Data accompanying ‘Microstructural controls on thermal crack damage and the presence of a temperature-memory effect during cyclic thermal stressing of rocks’ submitted for publication in Geophysical Research Letters

John Browning, Ali Daoud, Philip Meredith & Thomas Mitchell
Acoustic emissions (AE) and ultrasonic wave velocity data recorded during a series of high temperature thermal cracking experiments by Daoud et al., in the Rock and Ice Physics Laboratory of the University College London. The data gives the time and magnitude of AE output which were recorded contemporaneously whilst cyclically heating three rock types (A Slaufrudalur Granophyre, A Santorini Andesite and a Seljadalur Basalt). The ultrasonic wave velocity data was recorded pre- and post- heating....

Data from: A circuit mechanism for decision making biases and NMDA receptor hypofunction

Sean Cavanagh, Norman Lam, John Murray, Laurence Hunt & Steven Kennerley
Decision-making biases can be features of normal behaviour, or deficits underlying neuropsychiatric symptoms. We used behavioural psychophysics, spiking-circuit modelling and pharmacological manipulations to explore decision-making biases during evidence integration. Monkeys showed a pro-variance bias (PVB): a preference to choose options with more variable evidence. The PVB was also present in a spiking circuit model, revealing a potential neural mechanism for this behaviour. To model possible effects of NMDA receptor (NMDA-R) antagonism on this behaviour, we...

Data from: Contrasting trajectories of morphological diversification on continents and islands in the Afrotropical white-eye radiation

Julia J. Day, Frederico C. Martins, Joseph A. Tobias & David J. Murrell
Aim Morphological and lineage evolution are predicted to follow different patterns in island and mainland radiations. However, the extent to which these geographical contexts influence evolutionary trajectories remains poorly understood, in part because few studies have focused on species-rich clades colonising continents and archipelagos over comparable timeframes. Focusing on a diverse songbird clade radiating on the African continent and adjacent islands, we tested whether morphological evolution is best explained by adaptive or non-adaptive processes, and...

Data from: An integrative phylogenomic approach to elucidate the evolutionary history and divergence times of Neuropterida (Insecta: Holometabola)

Alexandros Vasilikopoulos, Bernhard Misof, Karen Meusemann, Doria Lieberz, Tomáš Flouri, Rolf G. Beutel, Oliver Niehuis, Torsten Wappler, Jes Rust, Ralph S. Peters, Alexander Donath, Lars Podsiadlowski, Christoph Mayer, Daniela Bartel, Alexander Böhm, Shanlin Liu, Paschalia Kapli, Carola Greve, James E. Jepson, Xingyue Liu, Xin Zhou, Horst Aspöck & Ulrike Aspöck
Background The latest advancements in DNA sequencing technologies have facilitated the resolution of the phylogeny of insects, yet parts of the tree of Holometabola remain unresolved. The phylogeny of Neuropterida has been extensively studied, but no strong consensus exists concerning the phylogenetic relationships within the order Neuroptera, and the timeline of diversification of thelineages of Neuropterida. Here, we assembled a novel transcriptomic dataset to address previously unresolved issues in the phylogeny of Neuropterida and to...
