Validation of an automated shape-matching algorithm for biplane radiographic spine osteokinematics and radiostereometric analysis error quantification

Arin M Ellingson & Craig C Kage
Biplane radiography and associated shape-matching provides non-invasive, dynamic, 3D osteo- and arthrokinematic analysis. Due to the complexity of data acquisition, each system should be validated for the anatomy of interest. The purpose of this study was to assess our system’s acquisition methods and validate a custom, automated 2D/3D shape-matching algorithm relative to radiostereometric analysis (RSA) for the cervical and lumbar spine. Additionally, two sources of RSA error were examined via a Monte Carlo simulation: 1)...

Data from: Snapshot Serengeti, high-frequency annotated camera trap images of 40 mammalian species in an African savanna

Alexandra B. Swanson, Margaret Kosmala, Chris J. Lintott, Robert J. Simpson, Arfon Smith & Craig Packer
Camera traps can be used to address large-scale questions in community ecology by providing systematic data on an array of wide-ranging species. We deployed 225 camera traps across 1,125 km2 in Serengeti National Park, Tanzania, to evaluate spatial and temporal inter-species dynamics. The cameras have operated continuously since 2010 and had accumulated 99,241 camera-trap days and produced 1.2 million sets of pictures by 2013. Members of the general public classified the images via the citizen-science...

Data from: Moose movement rates are altered by wolf presence in two ecosystems

Mark A. Ditmer, John R. Fieberg, Ron A. Moen, Steven K. Windels, Seth P. Stapleton & Tara R. Harris
Predators directly impact prey populations through lethal encounters, but understanding non-lethal, indirect effects is also critical because foraging animals often face tradeoffs between predator avoidance and energy intake. Quantifying these indirect effects can be difficult even when it is possible to monitor individuals that regularly interact. Our goal was to understand how movement and resource selection o a predator (wolves; Canis lupus) influences the movement behavior of a prey species (moose; Alces alces). We tested...

Data from: From cacti to carnivores: improved phylotranscriptomic sampling and hierarchical homology inference provide further insight into the evolution of Caryophyllales

Joseph Frederic Walker, Ya Yang, Tao Feng, Alfonso Timoneda, Jessica Mikenas, Vera Hutchison, Caroline Edwards, Ning Wang, Sonia Ahluwalia, Julia Olivieri, Nathanael Walker-Hale, Lucas C. Majure, Raúl Puente, Gudrun Kadereit, Maximillian Lauterbach, Urs Eggli, Hilda Flores-Olvera, Helga Ochoterena, Samuel F. Brockington, Michael J. Moore & Stephen A. Smith
Premise of the Study— The Caryophyllales contains ~12,500 species and is known for its cosmopolitan distribution, convergence of trait evolution, and extreme adaptations. Some relationships within the Caryophyllales, like those of many large plant clades, remain unclear and phylogenetic studies often recover alternative hypotheses. We explore the utility of broad and dense transcriptome sampling across the order for resolving evolutionary relationships in Caryophyllales. Methods— We generated 84 transcriptomes and combined these with 224 publicly available...

Data from: White matter alterations in Parkinson's disease with normal cognition precede grey matter atrophy

Ivan Rektor, Alena Svátková, Lubomir Vojtísek, Iva Zikmundova, Jirí Vanicek, András Király & Nikoletta Szabó
Introduction: While progressive MRI brain changes characterize advanced Parkinson's disease (PD), little has been discovered about structural alterations in the earliest phase of the disease, i.e. in patients with motor symptoms and with normal cognition. Our study aimed to detect grey matter (GM) and white matter (WM) changes in PD patients without cognitive impairment. Methods: Twenty PD patients and twenty-one healthy controls (HC) were tested for attention, executive function, working memory, and visuospatial and language...

Data from: Transcriptomic basis of genome by genome variation in a legume-rhizobia mutualism

Liana T. Burghardt, Joseph Guhlin, Chan Lan Chun, Junqi Liu, Robert M. Stupar, Michael J. Sadowsky, Nevin D. Young & Peter Tiffin
In the legume-rhizobia mutualism, the benefit each partner derives from the other depends on the genetic identity of both host and rhizobial symbiont. To gain insight into the extent of genome x genome interactions on hosts at the molecular level and to identify potential mechanisms responsible for the variation, we examined host gene expression within nodules (the plant organ where the symbiosis occurs) of four genotypes of Medicago truncatula grown with either Ensifer meliloti or...

Data from: Fitness of Arabidopsis thaliana mutation accumulation lines whose spontaneous mutations are known

Charles B. Fenster, Matthew Thomas Rutter, Angela J. Roles, Jeffrey K. Conner, Ruth G. Shaw, Frank Holcomb Shaw, Korbinian Schneeberger, Stephan Ossowski & Detlef Weigel
Despite the fundamental importance of mutation to the evolutionary process, we have little knowledge of the direct consequences of specific spontaneous mutations to the fitness of the organism. Combining results of whole-genome sequencing with repeated field assays of survival and reproduction, we quantify the combined effects on fitness of spontaneous mutations identified in Arabidopsis thaliana. We demonstrate that the effects are beneficial, deleterious or neutral depending on the environmental context. Some lines, bearing mutations disrupting...

Data from: Global biogeography of mating system variation in seed plants

David A. Moeller, Ryan D. Briscoe Runquist, Annika M. Moe, Monica A. Geber, Carol Goodwillie, Pierre-Olivier Cheptou, Christopher G. Eckert, Elizabeth Elle, Mark O. Johnston, Susan Kalisz, Richard H. Ree, Risa D. Sargent, Mario Vallejo-Marin & Alice A. Winn
Latitudinal gradients in biotic interactions have been suggested as causes of global patterns of biodiversity and phenotypic variation. Plant biologists have long speculated that outcrossing mating systems are more common at low than high latitudes owing to a greater predictability of plant–pollinator interactions in the tropics; however, these ideas have not previously been tested. Here, we present the first global biogeographic analysis of plant mating systems based on 624 published studies from 492 taxa. We...

Data from: Abiotic and biotic predictors of macroecological patterns in bird and butterfly coloration

Rhiannon L. Dalrymple, Habacuc Flores-Moreno, Darrell J. Kemp, Thomas E. White, Shawn W. Laffan, Frank A. Hemmings, Timothy D. Hitchcock & Angela T. Moles
Animal color phenotypes are invariably influenced by both their biotic community and the abiotic environments. A host of hypotheses have been proposed for how variables such as solar radiation, habitat shadiness, primary productivity, temperature, rainfall and community diversity might affect animal color traits. However, while individual factors have been linked to coloration in specific contexts, little is known about which factors are most important across broad taxonomic and geographic scales. Using data collected from 570...

Data from: Exams disadvantage women in introductory biology

Sehoya Cotner, Shima Salehi & Cissy J. Ballen
The gender gap in STEM fields has prompted a great deal of discussion, but what factors underlie performance deficits remain poorly understood. We show that female students underperformed on exams compared to their male counterparts across ten large introductory biology course sections in fall 2016 (N > 1500 students). Females also reported higher levels of test anxiety and course-relevant science interest. Results from mediation analyses revealed an intriguing pattern: for female students only, and regardless...

Data from: Multivariate phenotypic selection on a complex sexual signal

Jessie C. Tanner, Jessica L. Ward, Ruth G. Shaw & Mark A. Bee
Animal signals are complex, comprising multiple components that receivers may use to inform their decisions. Components may carry information of differing value to receivers, and selection on one component could modulate or reverse selection on another, necessitating a multivariate approach to estimating selection gradients. However, surprisingly few empirical studies have estimated the strength of phenotypic selection on complex signals with appropriate design and adequate power to detect non-linear selection. We used phonotaxis assays to measure...

Data from: Coordination of fictive motor activity in the larval zebrafish is generated by non-segmental mechanisms

Timothy D. Wiggin, Jack H. Peck & Mark A. Masino
The cellular and network basis for most vertebrate locomotor central pattern generators (CPGs) is incompletely characterized, but organizational models based on known CPG architectures have been proposed. Segmental models propose that each spinal segment contains a circuit that controls local coordination and sends longer projections to coordinate activity between segments. Unsegmented/continuous models propose that patterned motor output is driven by gradients of neurons and synapses that do not have segmental boundaries. We tested these ideas...

Data from: Restored tallgrass prairies have reduced phylogenetic diversity compared with remnants

Rebecca S. Barak, Evelyn W. Williams, Andrew L. Hipp, Marlin L. Bowles, Gabriela M. Carr, Robert Sherman & Daniel J. Larkin
Ecological restoration is critical for mitigating habitat loss and providing ecosystem services. However, restorations often have lower diversity than remnant, reference sites. Phylogenetic diversity is an important component of biodiversity and ecosystem function that has only recently been used to evaluate restoration outcomes. To move towards prediction in the restoration of biodiversity, it is necessary to understand how phylogenetic diversity of restorations compares with that of reference sites, and where deficits are found, to evaluate...

Data from: Life history as a constraint on plasticity: developmental timing is correlated with phenotypic variation in birds

Emilie C. Snell-Rood, Eli M. Swanson & Rebecca L. Young
Understanding why organisms vary in developmental plasticity has implications for predicting population responses to changing environments and the maintenance of intraspecific variation. The epiphenotype hypothesis posits that the timing of development can constrain plasticity—the earlier alternate phenotypes begin to develop, the greater the difference that can result amongst the final traits. This research extends this idea by considering how life history timing shapes the opportunity for the environment to influence trait development. We test the...

Urbanization impacts apex predator gene flow but not genetic diversity across an urban-rural divide

Daryl R Trumbo, Patricia E Salerno, Kenneth Logan, Mat Alldredge, Roderick B Gagne, Christopher P Kozakiewicz, Simona Kraberger, Nick Fountain-Jones, Meggan E Craft, Scott Carver, Holly B Ernest, Kevin Crooks, Sue VandeWoude & W. Chris Funk
Apex predators are important indicators of intact natural ecosystems. They are also sensitive to urbanization because they require broad home ranges and extensive contiguous habitat to support their prey base. Pumas (Puma concolor) can persist near human developed areas, but urbanization may be detrimental to their movement ecology, population structure, and genetic diversity. To investigate potential effects of urbanization in population connectivity of pumas, we performed a landscape genomics study of 130 pumas on the...
