Data from: Wall structure and material properties cause viscous damping of swimbladder sounds in the oyster toadfish Opsanus tau

Michael L. Fine, Terrence L. King, Heba Ali, Nehan Sidker & Timothy M. Cameron
Despite rapid damping, fish swimbladders have been modelled as underwater resonant bubbles. Recent data suggest that swimbladders of sound-producing fishes use a forced rather than a resonant response to produce sound. The reason for this discrepancy has not been formally addressed, and we demonstrate, for the first time, that the structure of the swimbladder wall will affect vibratory behaviour. Using the oyster toadfish Opsanus tau, we find regional differences in bladder thickness, directionality of collagen...

Data from: Toward translating near-infrared spectroscopy oxygen saturation data for the non-invasive prediction of spatial and temporal hemodynamics during exercise

Laura Ellwein, Margaret M. Samyn, Michael Danduran, Sheila Schindler-Ivens, Stacy Liebham, & John F. LaDisa
Image-based computational fluid dynamics (CFD) studies conducted at rest have shown that atherosclerotic plaque in the thoracic aorta (TA) correlates with adverse wall shear stress (WSS), but there is a paucity of such data under elevated flow conditions. We developed a pedaling exercise protocol to obtain phase contrast magnetic resonance imaging (PC-MRI) blood flow measurements in the TA and brachiocephalic arteries during three-tiered supine pedaling at 130, 150, and 170 % of resting heart rate...

Data from: Predator diversity reduces habitat colonization by mosquitoes and midges

Ethan G. Staats, Salvatore J. Agosta & James R. Vonesh
Changes in predator diversity via extinction and invasion are increasingly widespread and can have important ecological and socio-economic consequences. Anticipating and managing these consequences requires understanding how predators shape ecological communities. Previous predator biodiversity research has focused on post-colonization processes. However, predators can also shape communities by altering patterns of prey habitat selection during colonization. The sensitivity of this non-consumptive top down mechanism to changes in predator diversity is largely unexamined. To address this gap,...

Data from: Effects of roads and land use on frog distributions across spatial scales and regions in the eastern and central United States

Charbonnier, Andreia Dantas, Elizabeth Forys, Miran Foster, Jaquelyn General, Kristen S. Genet, Macie Hanneken, Kyle R. Hess, Shane A. Hill, Faisal Iqbal, Nancy E. Karraker, Eran S. Kilpatrick, Tom A. Langen, James Langford, Kathryn Lauer, Alison J. McCarthy, Joseph Neale … & Mohammad Tasleem
Aim: Understanding the scales over which land use affects animal populations is critical for conservation planning, and it can provide information about the mechanisms that underlie correlations between species distributions and land use. We used a citizen-science database of anuran surveys to examine the relationship between road density, land use, and the distribution of frogs and toads across spatial scales and regions of the United States. Location: Eastern and Central United States Methods: We compiled...

Data from: Microbiota-driven transcriptional changes in prefrontal cortex override genetic differences in social behavior

Gene-environment interactions impact the development of neuropsychiatric disorders, but the relative contributions are unclear. Here, we identify gut microbiota as sufficient to induce depressive-like behaviors in genetically distinct mouse strains. Daily gavage of saline in non-obese diabetic (NOD) mice induced a social avoidance behavior that was not observed in C57BL/6 mice. This was not observed in NOD animals with depleted microbiota via oral administration of antibiotics. Transfer of intestinal microbiota, including members of the Clostridiales,...

Data from: Can plan recommendations improve the coverage decisions of vulnerable populations in health insurance marketplaces?

Andrew J. Barnes, Yaniv Hanoch & Thomas Rice
Objective: The Affordable Care Act’s marketplaces present an important opportunity for expanding coverage but consumers face enormous challenges in navigating through enrollment and re-enrollment. We tested the effectiveness of a behaviorally informed policy tool—plan recommendations—in improving marketplace decisions. Study Setting: Data were gathered from a community sample of 656 lower-income, minority, rural residents of Virginia. Study Design: We conducted an incentive-compatible, computer-based experiment using a hypothetical marketplace like the one consumers face in the federally-facilitated...

Data from: Spatial variation in Allee effects influences patterns of range expansion

Jonathan A. Walter, Derek M. Johnson & Kyle J. Haynes
Allee effects are thought to slow range expansion and contribute to stable range boundaries. Recent studies have shown Allee effects to vary spatiotemporally due to influences of environmental heterogeneity on population processes. Gradients in Allee effects might occur as a species' range approaches suboptimal conditions while expanding into new territory. Allee effects could exhibit patchiness if drivers of positive density dependence (e.g., mate finding rates) are influenced by habitat patchiness. However, theoretical studies have largely...

Data from: Commercial harvest and export of snapping turtles (Chelydra serpentina) in the United States: trends and the efficacy of size limits at reducing harvest

Benjamin C. Colteaux & Derek M. Johnson
As Asian turtle populations have crashed, China has increasingly turned to international import to meet domestic demand, which has increased pressure on global turtle populations. Snapping turtles (Chelydra serpentina) are being harvested in unprecedented numbers in the United States (US) to meet the needs of this international market. Here we report US snapping turtle live export from 1999 to 2013, and for the first time test the effectiveness of size limits in reducing commercial harvest...
