Athletic Training Student Patient Encounter Characteristics during Immersive and Non-Immersive Experiences: A Report From the Athletic Training Clinical Network

Bailey Jones, Julie M. Cavallario, Cailee-Welch Bacon, Stacey Walker & Bonnie Van Lunen
Context: Professional athletic training programs are now required to include at least one immersive clinical experience (ICE), which allow students to see more patient-care opportunities and job responsibilities that athletic trainers complete than those at a non-immersive clinical experience (N-ICE). Therefore, the purpose of this study was to compare the characteristics of patient encounters (PEs) that occurred at ICEs and N-ICEs. Methods: This study used a multi-site panel design in which 336 athletic training students...

Individual-Based-Model used in \"Population context matters: predicting effects of metabolic stress mediated by food availability and predation with an agent- and energy budget-based model\"

Maxime Vaugeois, Valery E Forbes, Paul A Venturelli, Chiara Accolla & Stephanie L Hummel
This is the programming software code of the model developed to investigate the population-level impacts of a hypothetical, sublethal stressor that can affect an individual’s metabolism (growth, reproduction, maintenance, or assimilation) in systems in which population size is controlled by different combinations of food availability and predation pressure. The life cycle of fathead minnow (Pimephales promelas) is describe through their metabolism, using the Dynamic Energy Budget theory (DEB) and we represent the populations through an...

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...

Fish abundance data (fish per m) collected during the MACRO project in Mongolia. We collected fish assemblages in river networks of two different ecoregions, the Forest Steppe (FS) and Grassland (G), in 2017 and 2019.

Dataset for: Intercontinental analysis of temperate steppe stream food webs reveals consistent autochthonous support of fishes

Emily Arsenault, James Thorp, Michael Polito, Mario Minder, Walter Dodds, Flavia Tromboni, Alain Maasri, Mark Pyron, Bud Mendsaikhan, Amarbat Otgonganbat, Solongo Altangerel, Sudeep Chandra, Robert Shields, Caleb Artz & Hayat Bennadji
Quantifying the trophic basis of production for freshwater metazoa at broad spatial scales is key to understanding ecosystem function and has been a research priority for decades. However, previous lotic food web studies have been limited by geographic coverage or methodological constraints. We used compound-specific stable carbon isotope analysis of amino acids to estimate basal resource contributions to fish consumers in streams spanning grassland, montane, and semi-arid ecoregions of the temperate steppe biome on two...

Data from: Local pain dynamics during constant exhaustive exercise

Agnė Slapšinskaitė, Selen Razon, Natàlia Balagué, Robert Hristovski, Gershon Tenenbaum & Natàlia Balagué Serre
The purpose of this study was to delineate the topological dynamics of pain and discomfort during constant exercise performed until volitional exhaustion. Eleven physical education students were tested while cycling and running at a “hard” intensity level (e.g., corresponding to Borg’s RPE (6–20) = 15). During the tests, participants reported their discomfort and pain on a body map every 15s. “Time on task” for each participant was divided into five equal non-overlapping temporal windows within...

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: Parasite and host elemental content and parasite effects on host nutrient excretion and metabolic rate

Nicole Chodkowski & Randall J. Bernot
Ecological stoichiometry uses the mass balance of elements to predict energy and elemental fluxes across different levels of ecological organization. A specific prediction of ecological stoichiometry is the growth rate hypothesis (GRH), which states that organisms with faster growth or reproductive rates will require higher phosphorus content for nucleic acid and protein synthesis. Although parasites are found ubiquitously throughout ecosystems, little is understood about how they affect nutrient imbalances in ecosystems. We (1) tested the...

Buck Creek fish samplings

Paul DeRolf, Mark Pyron & Drew Holloway
Buck Creek is a spring-fed, cool-water tributary of the West Fork White River, Indiana. The Muncie Bureau of Water Quality sampled fishes and monitored water temperature in Buck Creek annually from 1986-2018. For this study, we utilized long-term fish data from the Bureau of Water Quality to evaluate spatial and temporal changes in the fish assemblages of Buck Creek in Delaware County, Indiana, USA. Non-metric multidimensional scaling (NMDS) was used to describe changes in the...

Data from: Environmental estrogens cause predation-induced population decline in a freshwater fish

Daniel C. Rearick, Jessica Ward, Paul Venturelli & Heiko Schoenfuss
Understanding population-level effects of environmental stressors on aquatic biota requires knowledge of the direct adverse effects of pollutants on individuals and species interactions that relate to survival and reproduction. Here, we connect behavioral assays with survival trials and a modeling approach to quantify changes in antipredator escape performance of a larval freshwater fish following exposure to an environmental estrogen, and predict changes in population abundance. We quantified the effects of short-term (21 d) exposure to...

Antipredator responses of embryos and larval fathead minnows

Jessica Ward & Chris Crowder
Most research on embryonic learning and behavior in aquatic vertebrates has focused on fitness benefits after hatching, but the ability of embryos to perceive and respond to environmental stimuli may also have immediate adaptive value. Here, we examined whether fathead minnow embryos, Pimephales promelas, detect and respond to cues indicative of predation risk, and whether the embryonic environment influences behavior after hatching. We compared the behavior of 5-day post-fertilization (dpf) embryos reared in the presence...

An introduction to the analysis of ranked response data

Holmes Finch
Researchers in many disciplines work with ranking data. This data type is unique in that it is often deterministic in nature (the ranks of items k-1 determine the rank of item k), and the difference in a pair of rank scores separated by k units is equivalent regardless of the actual values of the two ranks in the pair. Given its unique qualities, there are specific statistical analyses and models designed for use with ranking...

Heavy-load exercise in older adults activates vasculogenesis and has a stronger impact on muscle gene expression than in young adults

Kaare M. Gautvik, Ole K. Olstad, Ulrika Raue, Vigdis T. Gautvik, Karl J. Kvernevik, Tor P. Utheim, Solveig Ravnum, Camilla Kirkegaard, Håvard Wiig, Garan Jones, Luke C. Pilling, Scott Trappe, Truls Raastad & Sjur Reppe
Abstract Background A striking effect of old age is the involuntary loss of muscle mass and strength leading to sarcopenia and reduced physiological functions. However, effects of heavy-load exercise in older adults on diseases and functions as predicted by changes in muscle gene expression have been inadequately studied. Methods Thigh muscle global transcriptional activity (transcriptome) was analyzed in cohorts of older and younger adults before and after 12–13 weeks heavy-load strength exercise using Affymetrix microarrays....

Data from: Conspicuous signal evolution in heterogeneous environments

Jessica L. Ward
A fundamental prediction of reproductive signal evolution is that selection should favor male courtship signals that are conspicuous with respect to the surrounding media. However, many species live in heterogeneous environments where spatiotemporal variability can degrade the efficacy of signals tuned to specific conditions. One rarely considered solution to this problem is to evolve generalized signals that can effectively transmit information under most of the conditions that are likely to be encountered. Here, I present...

Data from: Trophic interactions regulate peatland carbon cycling

Kevin Wyatt
Peatlands are the most efficient natural ecosystems for long-term storage of atmospheric carbon. Our understanding of peatland carbon cycling is based entirely on bottom-up controls regulated by low nutrient availability. Recent studies have shown that top-down controls through predator-prey dynamics can influence ecosystem function, yet this has not been evaluated in peatlands to date. Here, we used a combination of nutrient enrichment and trophic-level manipulation to test the hypothesis that interactions between nutrient availability (bottom-up)...

Fish assemblages on two continents

Mark Pyron
Aim: Fish assemblages –whether defined by taxonomy or functional traits—respond to regional and local habitat variation. We sampled rivers of Mongolia and the western United States (US) to determine the scale at which habitat could predict fish assemblage variation, classified by taxonomy or functional traits. Our hypothesis was that fish assemblages could be predicted using valley-scale hydrogeomorphology and reach-scale hydrology. We further predicted that if valley-scale variables explained high variation in fish assemblages then reach-scale...

Diet overlap among non-native trout species and native Cutthroat Trout (Oncorhynchus clarkii) in two U.S. ecoregions

Mario Minder, Emily Arsenault, Bolortsetesg Erdenee, Alain Maasri & Mark Pyron
The invasion of freshwater ecosystems by non-native species can constitute a significant threat to native species and ecosystem health. Non-native trouts have long been stocked in areas where native trouts occur and have negatively impacted native trouts through predation, competition, and hybridization. This study encompassed two seasons of sampling efforts across two ecoregions of the western United States: The Great Basin in summer 2016 and the Yellowstone River Basin in summer 2017. We found significant...
