Data from: Monopolar detection thresholds predict spatial selectivity of neural excitation in cochlear implants: implications for speech recognition

Ning Zhou
The objectives of the study were to (1) investigate the potential of using monopolar psychophysical detection thresholds for estimating spatial selectivity of neural excitation with cochlear implants and to (2) examine the effect of site removal on speech recognition based on the threshold measure. Detection thresholds were measured in Cochlear Nucleus® device users using monopolar stimulation for pulse trains that were of (a) low rate and long duration, (b) high rate and short duration, and...

Mortality data from the Baja California peninsula of Mexico

Ryan Schacht
A consistent finding from contemporary Western societies is that women outlive men. However, what is unclear is whether sex differences in survival are constant across varying socio-ecological conditions. We test the universality of the female survival advantage with mortality data from a 19th century population in the Baja California peninsula of Mexico. When examined simply, we find evidence for a male-biased survival advantage. However, results from Cox regression clearly show the importance of age intervals...

Asymmetrical effects of temperature on stage-structured predator-prey interactions

Andrew Davidson, Elizabeth Hamman, Michael McCoy & James Vonesh
Warming can impact consumer-resource interactions through multiple mechanisms. For example, warming can both alter the rate at which predators consume prey and the rate prey develop through vulnerable life stages. Thus, the overall effect of warming on consumer-resource interactions will depend upon the strength and asymmetry of warming effects on predator and prey performance. Here, we quantified the temperature dependence of both 1) density-dependent predation rates for two dragonfly nymph predators on a shared mosquito...

Structural competency in pre-health and health professional learning : A scoping review

Courtney Caiola, Taylor Nelson, Kristin Black, Christie Calogero, Irma Corral, Kaitlin Guard & Amanda Haberstroh
Long-standing health inequities in the United States persist and, in some cases, are worsening (1). Health inequities are not just disparate health outcomes among certain populations, rather they are avoidable and unjust systemic differences in health outcomes based on the position people and communities occupy in a social hierarchy (2). Social and structural factors significantly contribute to these inequities and include factors such as racism (3), gender oppression (4), housing segregation (4), mass incarceration (4),...

Dual role of CsrA in regulating the hemolytic activity of Escherichia coli O157:H7

Zhibin Sun, Ning Zhou, Wenting Zhang, Yan Xu & Yu-Feng Yao
Post-transcriptional global carbon storage regulator A (CsrA) is a sequence-specific RNA-binding protein involved in the regulation of multiple bacterial processes. Hemolysin is an important virulence factor in the enterohemorrhagic Escherichia coli O157:H7 (EHEC). Here, we show that CsrA plays a dual role in the regulation of hemolysis in EHEC. CsrA significantly represses plasmid-borne enterohemolysin (EhxA)-mediated hemolysis and activates chromosome-borne hemolysin E (HlyE)-mediated hemolysis through different mechanisms. RNA structure prediction revealed a well-matched stem-loop structure with...

Alpha: A Fortran program for simulating porewater radiolysis

Joel DeWitt
The radiolysis of porewaters by uranium, thorium, and potassium in mineral grains is a recognised source of molecular hydrogen in rock- and sediment-hosted fluids. This radiolytic hydrogen is of geomicrobiological interest as a potential energy source (electron donor) for microbial metabolism, especially in energy-limited settings such as the marine deep biosphere or the subsurface of Mars. Previous efforts to predict the production of radiolytic hydrogen from columns of rock and sediment have tended to rely...

Addressing Perinatal Mental Health Equity For Marginalized Birthing People in the US: A Scoping Review Protocol

Karlene Cunningham, Krupa Trivedi, Amanda Haberstroh & Ke' Craig
Estimates suggest that Black women are twice as likely to experience perinatal mood disorders and Black, Asian, and Native American birthing people are less likely to be screened for postpartum depression. Less is known about other marginalized groups such as sexual and gender minorities. Despite these disparities, seemingly less focus has been placed on the unique considerations and strategies to close the gaps in perinatal mental health and promote health equity. The purpose of this...

Perception of speaker sincerity in complex social interactions by cochlear implant users

Ning Zhou
Understanding insincere language, for example sarcasm and teasing, is a fundamental element of communication and crucial for maintaining social relationships. This can be a challenging task for cochlear implant users (CIs) who receive degraded suprasegmental information important for perceiving a speaker’s attitude. We measured perception of speaker sincerity (literal positive, literal negative, sarcasm, and teasing) in 16 adults with CIs using an established video inventory. Participants were presented with audio-only and audio-visual social interactions between...

Nurses' self-care strategies: A mapping review protocol

Laura Gantt & Amanda Haberstroh
The aim of this review is to provide a map of the literature identifying studies that seek to answer the following question: what self-care strategies do nurses find most effective in allowing them to continue practicing as nurses? To accomplish this, the mapping review will utilize broad search strategies across several databases and within high-impact nursing journals.

Gene expression in male and female sticklebacks from populations with convergent and divergent throat coloration

Jeffrey McKinnon, W. Burns Newsome & Christopher Balakrishnan
Understanding of genetic mechanisms underlying variation in sexual dichromatism remains limited, especially for carotenoid-based colors. We addressed this knowledge gap in a gene expression study with threespine stickleback. We compared male and female throat tissues across five populations, including two in which female red coloration has evolved convergently. We found that the expression of individual genes, gene ontologies, and coexpression networks associated with red female color within a population differed between California and British Columbia...

Analysis of oil vapor diffusion after oil spill from tank group based on wind tunnel experiment and numerical simulation

Chunyan Wu, Weiqiu Huang, Feng Chen, Xue Xu, Xufei Li, Xinya Wang, Yongyin Zheng & Ning Zhou
The diffusion of oil vapor after oil spill from tank caused serious consequences. It is studied by combining wind tunnel experiment and numerical simulation. Results show that the higher the fire dike, the more oil vapor accumulates at the inner corner of fire dike; the explosion limit area is the largest when the oil spills in front of single tank on the windward side; concentration of multi-spills will superimpose to induce the presenting of multi-explosion...

Data from: Millipede taxonomy after 250 years: classification and taxonomic practices in a mega-diverse yet understudied arthropod group

Michael S. Brewer, Petra Sierwald & Jason E. Bond
BACKGROUND: The arthropod class Diplopoda is a mega-diverse group comprising >12,000 described millipede species. The history of taxonomic research within the group is tumultuous and, consequently, has yielded a questionable higher-level classification. Few higher-taxa are defined using synapomorphies, and the practice of single taxon descriptions lacking a revisionary framework has produced many monotypic taxa. Additionally, taxonomic and geographic biases render global species diversity estimations unreliable. We test whether the ordinal taxa of the Diplopoda are...

Data from: Reproductive isolation related to mimetic divergence in the poison frog Ranitomeya imitator

Evan Twomey, Jacob S. Vestergaard & Kyle Summers
In a mimetic radiation—when a single species evolves to resemble different model species—mimicry can drive within-species morphological diversification, and, potentially, speciation. While mimetic radiations have occurred in a variety of taxa, their role in speciation remains poorly understood. We study the Peruvian poison frog Ranitomeya imitator, a species that has undergone a mimetic radiation into four distinct morphs. Using a combination of colour–pattern analysis, landscape genetics and mate-choice experiments, we show that a mimetic shift...

Data from: The evolutionary enigma of mixed mating systems in plants: occurrence, theoretical explanations, and empirical evidence

Carol Goodwillie, Susan Kalisz & Christopher G. Eckert
Mixed mating, in which hermaphrodite plant species reproduce by both self- and cross-fertilization, presents a challenging problem for evolutionary biologists. Theory suggests that inbreeding depression, the main selective factor opposing the evolution of selfing, can be purged with self-fertilization, a process that is expected to yield pure strategies of either outcrossing or selfing. Here we present updated evidence suggesting that mixed mating systems are frequent in seed plants. We outline the floral and pollination mechanisms...

Data from: Sex ratio effects on reproductive strategies in humans

Ryan Schacht & Monique Borgerhoff Mulder
Characterizations of coy females and ardent males are rooted in models of sexual selection that are increasingly outdated. Evolutionary feedbacks can strongly influence the sex roles and subsequent patterns of sex differentiated investment in mating effort, with a key component being the adult sex ratio (ASR). Using data from eight Makushi communities of southern Guyana, characterized by varying ASRs contingent on migration, we show that even within a single ethnic group, male mating effort varies...

Data from: Temporal dynamics of the genetic clines of invasive European green crab (Carcinus maenas) in eastern North America

Sarah J. Lehnert, Claudio DiBacco, Nicholas W. Jeffery, April M.H. Blakeslee, Jonatan Isaksson, Joe Roman, Brendan F. Wringe, Ryan R.E. Stanley, Kyle Matheson, Cynthia H. McKenzie, Lorraine C. Hamilton, Ian R. Bradbury, Ryan R. E. Stanley & April M. H. Blakeslee
Two genetically distinct lineages of European green crabs (Carcinus maenas) were independently introduced to eastern North America, the first in the early 19th century and the second in the late 20th century. These lineages first came into secondary contact in southeastern Nova Scotia, Canada (NS), where they hybridized, producing latitudinal genetic clines. Previous studies have documented a persistent southward shift in the clines of different marker types, consistent with existing dispersal and recruitment pathways. We...
