Turning turtle: Scaling relationships and self-righting ability in Chelydra serpentina

Jonathan Codd
Testudines are susceptible to inversion and self-right using their necks, limbs, or both, to generate enough mechanical force to flip over. We investigated how shell morphology, neck length, and self-righting biomechanics scale with body mass during ontogeny in Chelydra serpentina, which uses neck-powered self-righting. We found that younger turtles flipped over twice as fast as older individuals. A simple geometric model predicted the relationships of shell shape and self-righting time with body mass. Conversely, neck...

Adaptation at different points along antibiotic concentration gradients

Mato Lagator, Hildegard Uecker & Paul Neve
Antibiotic concentrations vary dramatically in the body and the environment. Hence, understanding the dynamics of resistance evolution along antibiotic concentration gradients is critical for predicting and slowing the emergence and spread of resistance. While it has been shown that increasing the concentration of an antibiotic slows resistance evolution, how adaptation to one antibiotic concentration correlates with fitness at other points along the gradient has not received much attention. Here, we selected populations of Escherichia coli...

Tripartite symbioses regulate plant-soil feedback in alder

Agnes Ardanuy, Jennifer KM Walker, Ully Kritzler, Andy FS Taylor & David Johnson
• Plant-soil feedbacks regulate plant productivity and diversity, but potential mechanisms underpinning such feedbacks, such as the allocation of recent plant assimilate, remain largely untested especially for plants forming tripartite symbioses. • We tested how soils from under alder (Alnus glutinosa) and beneath other species of the same and different families affected alder growth and nutrition, and colonisation of roots by nitrogen-fixing Frankia bacteria and ectomycorrhizal fungi. We also measured how the soil environment affected...

The release of inertial instability near an idealized zonal jet

Callum Thompson & David M. Schultz
Inertial instability is a hydrodynamic instability that occurs in strong anticyclonic flow and is typically diagnosed by negative absolute vorticity in the Northern Hemisphere. As such, inertial instability is often observed on the anticyclonic-shear side of jet streams, yet the release of the instability in this environment is still poorly understood. We simulate the release of inertial instability near an idealized midlatitude zonal jet compared a control simulation with no instability. We find that the...

Data Collected During Simultaneous Neutron Powder Diffraction and Microwave Characterisation at Elevated Temperatures

Michael Barter, Gemma Smith, Sihai Yang, Martin Schröder, Martin Owen Jones & Adrian Porch
This dataset contains data collected during simultaneous neutron diffraction and microwave characterisation of a metal-organic framework (MOF), MFM-170, at elevated temperatures. The experiment consisted of the desolvation of the as synthesised MOF sample by flowing nitrogen gas heated to 150 °C through the sample, followed by rehydration of the sample by flowing air through the sample, and subsequent desolvation at a higher flow rate. Temperatures throughout the experiment are given (time and temperature) along with...

Supplementary Information for Phylogenetic analyses of ray-finned fishes (Actinopterygii) using collagen type I protein sequences

Virginia Harvey, Joseph Keating & Michael Buckley
Ray-finned fishes (Actinopterygii) are the largest and most diverse group of vertebrates, comprising over half of all living vertebrate species. Phylogenetic relationships between ray-finned fishes have historically pivoted on the study of morphology, which has notoriously failed to resolve higher-order relationships, such as within the percomorphs. More recently, comprehensive genomic analyses have provided further resolution of actinopterygian phylogeny, including higher-order relationships. Such analyses are rightfully regarded as the ‘gold standard’ for phylogenetics. However, DNA retrieval...

Datasets associated with: Late Holocene spread of pastoralism coincides with endemic megafaunal extinction on Madagascar

Sean Hixon, Kristina Douglass, Brooke Crowley, Lucien Rakotozafy, Geoffrey Clark, Atholl Anderson, Simon Haberle, Jean Freddy Ranaivoarisoa, Mike Buckley, Salomon Fidiarisoa, Balzac Mbola & Douglas Kennett
Recently expanded estimates for when humans arrived on Madagascar (up to ~10,000 years ago) highlight questions about the causes of the island’s relatively late megafaunal extinctions (~2000-500 years ago). Introduced domesticated animals could have contributed to extinctions, but the arrival times and past diets of exotic animals are poorly known. To conduct the first explicit test of the potential for competition between introduced livestock and extinct endemic megafauna in southern and western Madagascar, we generated...

SARA module 3: NGS epitope sequencing: Illumina FASTQ files

Thomas Walker, Spyridon Megremis & Janine Lamb
We investigate the accumulated microbial and autoantigen antibody repertoire in adult-onset dermatomyositis patients sero-positive for TIF1γ (TRIM33) autoantibodies. We use an untargeted high-throughput approach which combines immunoglobulin disease-specific epitope-enrichment and identification of microbial and human antigens. We observe antibodies recognizing a wider repertoire of microbial antigens in dermatomyositis. Antibodies recognizing viruses and Poxviridae family species are significantly enriched. The identified autoantibodies recognise a large portion of the human proteome, including interferon regulated proteins; these proteins...

Swallowtail butterfly wing and tail measurements

Robert Nudds & Lydia Koutrouditsou
The European swallowtail butterfly (Papilio machaon) is so named, because of the long and narrow prominences extending from the trailing edge of their hindwings and, although not a true tail, they are referred to as such. Despite being a defining feature, an unequivocal function for the tails is yet to be determined, with predator avoidance (diverting an attack from the rest of the body), and enhancement of aerodynamic performance suggested. The swallowtail, however, is sexually...

Metadata for the characterization of Platynereis dumerilii cephalic and non-cephalic sensory cell types

Roger Revilla-I-Domingo, Vinoth Babu Veedin-Rajan, Monika Waldherr, Günther Prohaczka, Hugo Musset, Lukas Orel, Elliot Gerrard, Moritz Smolka, Matthias Farlik & Robert J. Lukas
Rhabdomeric Opsins (r-Opsins) serve as light-sensory molecules in cephalic eye photoreceptors of many invertebrates, but also play roles in additional sensory organs. This has prompted questions on the evolutionary relationship of the cell types, specifically if ancient r-Opsins cells possessed non-photosensory functions. By extracting and profiling cephalic and non-cephalic r-opsin1-expressing cell types of the marine bristleworm Platynereis dumerilii, we find evidence for shared and distinct identities between these two cell types. We establish that non-cephalic...

Productivity, niche availability, species richness and extinction risk: Untangling relationships using individual-based simulations

Euan Furness, Russell Garwood, Philip Mannion & Mark Sutton
It has been widely hypothesised that the productivity of an ecosystem affects the number of species that it can support. Despite decades of study, the nature, extent, and underlying mechanisms of this relationship are unclear. One suggested mechanism is the “more individuals” hypothesis (MIH). This proposes that productivity controls the number of individuals in the ecosystem, and that more individuals can be divided into a greater number of species before their population size is sufficiently...

Adverse positioning in mammography - observations of imaging features

Patsy Whelehan
This dataset consists of observations of mammographic images, plus three relevant variables used in the validation process for the measure of adverse positioning we developed based on the dataset. An expert observer generated the primary data by reviewing mammographic images to judge the presence or absence of a set of features developed through theory and consultation with other experts. The data can be reused by anyone wishing to learn and practice psychometric validation techniques, for...

Convex hull estimation of mammalian body segment parameters

Sam Coatham, William Sellers & Thomas Püschel
Obtaining accurate values for body segment parameters (BSPs) is fundamental in many biomechanical studies, particularly for gait analysis. Convex hulling, where the smallest-possible convex object that surrounds a set of points is calculated, has been suggested as an effective and time-efficient method to estimate these parameters in extinct animals, where soft tissues are rarely preserved. We investigated the effectiveness of convex hull BSP estimation in a range of extant mammals, to inform the potential future...

Data from: Fossils improve phylogenetic analyses of morphological characters

Nicolás Mongiardino Koch, Russell Garwood & Luke Parry
Fossils provide our only direct window into evolutionary events in the distant past. Incorporating them into phylogenetic hypotheses of living clades can help time-calibrate divergences, as well as elucidate macroevolutionary dynamics. However, the effect fossils have on phylogenetic reconstruction from morphology remains controversial. The consequences of explicitly incorporating the stratigraphic ages of fossils using tip-dated inference are also unclear. Here we use simulations to evaluate the performance of inference methods across different levels of fossil...

Do tradeoffs govern plant species responses to different global change treatments?

J. Adam Langley, Emily Grman, Kevin Wilcox, Meghan Avolio, Kimberly Komatsu, Scott Collins, Sally Koerner, Melinda Smith, Andrew Baldwin, William Bowman, Nona Chiariello, Anu Eskelinen, Harry Harmens, Mark Hovenden, Kari Klanderud, Rebecca McCulley, Vladimir Onipchenko, Clare Robinson & Katharine Suding
Plants are subject to tradeoffs among growth strategies such that adaptations for optimal growth in one condition can preclude optimal growth in another. Thus, we hypothesized that the response of plant species abundance to one global change treatment would relate inversely to the response to a second treatment, particularly for treatment combinations that accentuate distinct traits. To address this hypothesis, we examined plant species abundances in 39 global change experiments manipulating CO2, nitrogen, phosphorus, water,...

Home-based exercise for people living with frailty and chronic kidney disease: a mixed-methods pilot randomised controlled trial

Andrew Nixon, Theodoros Bampouras, Helen Gooch, Hannah Young, Kenneth Finlayson, Neil Pendleton, Sandip Mitra, Mark Brady & Ajay Dhaygude
Background and Aims: Frailty is highly prevalent in adults with chronic kidney disease (CKD) and is associated with adverse health outcomes. However, exercise training may improve physical function leading to associated improvements in outcomes. The EX-FRAIL CKD trial (ISRCTN87708989) aimed to inform the design of a randomised controlled trial (RCT) that investigates the efficacy of a progressive home-based exercise programme in pre-frail and frail older adults with CKD. Methods: Patients aged ≥65 years with CKD...
