Evolutionary studies are often limited by missing data that are critical to understanding the history of selection. Selection experiments, which reproduce rapid evolution under controlled conditions, are excellent tools to study how genomes evolve under selection. Here we present a genomic dissection of the Longshanks selection experiment, in which mice were selectively bred over 20 generations for longer tibiae relative to body mass, resulting in 13% longer tibiae in two replicates. We synthesized evolutionary theory,...

Data from: Trophic interactions and abiotic factors drive functional and phylogenetic structure of vertebrate herbivore communities across the Arctic tundra biome

Rees, Anna Skarin, Natalya Sokolova, Andrew H. Thornhill, Ingunn Tombre & Eeva M. Soininen
Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions and interactions with other species. The evolutionary and colonisation histories of communities are characterised by phylogenetic diversity, while functional diversity is indicative of abiotic and biotic conditions. The relationship between functional and phylogenetic diversity infers whether species functional traits are divergent (differing between related species) or convergent (similar among distantly related species). Biotic interactions...

Data from: Enamel hypoplasia and dental wear of North American late Pleistocene horses and bison: an assessment of nutritionally-based extinction models

Christina I. Barrón-Ortiz, Christopher N. Jass, Raúl Barrón-Corvera, Jennifer Austen & Jessica M. Theodor
Approximately 50,000 – 11,000 years ago many species around the world became extinct or were extirpated at a continental scale. The causes of the late Pleistocene extinctions have been extensively debated and continue to be poorly understood. Several extinction models have been proposed, including two nutritionally-based extinction models: coevolutionary disequilibrium and mosaic-nutrient models. These models draw upon the individualistic response of plant species to climate change to present a plausible scenario in which nutritional stress...

Geography, seasonality, and host‐associated population structure influence the fecal microbiome of a genetically depauparate Arctic mammal

Samantha Bird, Erin Prewer, Susan Kutz, Lisa-Marie Leclerc, Sibelle T. Vilaça & Christopher J. Kyle
The Canadian Arctic is an extreme environment with low floral and faunal diversity characterized by major seasonal shifts in temperature, moisture and daylight. Muskoxen (Ovibos moschatus) are one of few large herbivores able to survive this harsh environment. Microbiome research of the gastrointestinal tract may hold clues as to how muskoxen exist in the Arctic, but also how this species may respond to rapid environmental changes. In this study, we investigated the effects of season...

High-frequency measurements of aeolian saltation flux: time series data

Raleigh L. Martin, Jasper F. Kok, Chris H. Hugenholtz, Thomas E. Barchyn, Marcelo Chamecki & Jean T. Ellis
High-frequency (25-50 Hz) coupled observations of wind speed and aeolian saltation flux (i.e, the wind-blown movement of sand) were measured at three field sites: Jericoacoara, Brazil; Rancho Guadalupe, California; and Oceano, California. The dataset provided here contains the full record of raw and processed time series of saltation flux and wind speed measured at multiple heights above the sediment surface.

Implementing standardized provider documentation in a tertiary epilepsy clinic: supplemental material

Felipe J.S. Jones, Jason R. Smith, Neishay Ayub, Susan T. Herman, Jeffrey R. Buchhalter, Brandy E. Fureman, Sydney S. Cash, Daniel B. Hoch & Lidia M.V.R. Moura
Objective: To incorporate standardized documentation into an epilepsy clinic and use these standardized data to compare patients’ perception of epilepsy diagnosis to provider documentation. Methods: Using quality improvement methodology, we implemented interventions to increase documentation of epilepsy diagnosis, seizure frequency and type from 49.8% to 70% of adult non-employee patients seen by six providers over five months of routine clinical care. The main intervention consisted of an interactive SmartPhrase that mirrored a documentation template developed...

Data from: Opsin genes of select treeshrews resolve ancestral character states within Scandentia

Gwen Duytschaever, Mareike C. Janiak, Perry S. Ong, Konstans Wells, Nathaniel J. Dominy & Amanda D. Melin
Treeshrews are small, squirrel-like mammals in the order Scandentia, which is nested together with Primates and Dermoptera in the superordinal group Euarchonta. They are often described as living fossils, and researchers have long turned to treeshrews as a model or ecological analogue for ancestral primates. A comparative study of colour vision-encoding genes within Scandentia found a derived amino acid substitution in the long-wavelength sensitive opsin gene (OPN1LW) of the Bornean smooth-tailed treeshrew (Dendrogale melanura). The...
