Linking Foraging Behaviour and Habitat Preferences During Moult Across Multiple Populations of Red-Throated Diver.

Understanding the habitat use of individuals can facilitate methods to measure the degree to which populations will be affected by potential stressors. Such insights can be hard to garner for marine species that are inaccessible during phases of their annual cycles. Here, we quantify the link between foraging habitat and behaviour in an aquatic bird of high conservation concern, the red-throated diver () across three breeding populations (Finland, Iceland and Scotland) during their understudied moult period.

Portable Touchscreen Assessment of Motor Skill: A Registered Report of the Reliability and Validity of EDNA MoTap.

Portable and flexible administration of manual dexterity assessments is necessary to monitor recovery from brain injury and the effects of interventions across clinic and home settings, especially when in-person testing is not possible or convenient. This paper aims to assess the concurrent validity and test-retest reliability of a new suite of touchscreen-based manual dexterity tests (called ™) that are designed for portable and efficient administration. A minimum sample of 49 healthy young adults will be conveniently recruited.

Selection against domestication alleles in introduced rabbit populations.

Humans have moved domestic animals around the globe for thousands of years. These have occasionally established feral populations in nature, often with devastating ecological consequences. To understand how natural selection shapes re-adaptation into the wild, we investigated one of the most successful colonizers in history, the European rabbit.

Long-wavelength traveling waves of vasomotion modulate the perfusion of cortex.

Brain arterioles are active, multicellular complexes whose diameters oscillate at ∼ 0.1 Hz. We assess the physiological impact and spatiotemporal dynamics of vaso-oscillations in the awake mouse.

First Detection and Circulation of RHDV2 in New Zealand.

Rabbit haemorrhage disease virus 2 (RHDV2) is a highly pathogenic lagovirus that causes lethal disease in rabbits and hares (lagomorphs). Since its first detection in Europe in 2010, RHDV2 has spread worldwide and has been detected in over 35 countries so far. Here, we provide the first detailed report of the detection and subsequent circulation of RHDV2 in New Zealand.

A pilot study of the acceptability, efficacy, and iatrogenic effects of a brief dynamic norms intervention for reducing young adult alcohol use.

Background: Alcohol use and its related consequences are a public health problem among young adults. Building upon efficacious personalized normative feedback interventions, dynamic norms can be used to highlight the decreasing prevalence of alcohol use over time among young adults' peers, thereby increasing their motivation to change drinking consistent with the trend. Because limited research has examined dynamic norms feedback interventions for alcohol use, we examined the acceptability and initial efficacy of such an intervention, and potential iatrogenic effects of showing norms feedback about drinking to light drinkers and nondrinkers.

Cannabis to cope with COVID-19 in college.

Cannabis use in college students has increased over time and is linked to negative consequences. During the COVID-19 pandemic, many students experienced greater stress, which could heighten cannabis use and related consequences. This study was designed to clarify motivations for cannabis use that may link pandemic-related stressors to time spent high and cannabis-related consequences.

Age-related patterns in high-risk alcohol and cannabis use and their associations with positive and negative affect in young adulthood.

Objective: We examined age-varying associations between young adult simultaneous alcohol and marijuana/cannabis use (SAM) and heavy episodic drinking (HED) and positive and negative affect to inform harm reduction efforts.

Methods: Young adults reporting past-year alcohol use (n = 556; ages 19-25) were recruited in a state where alcohol and nonmedical cannabis use was legal for those 21 +. Participants provided 24 repeated monthly assessments.

A framework to unlock marine bird energetics.

Energetics can provide novel insights into the roles of animals, but employing an energetics approach has traditionally required extensive empirical physiological data on the focal species, something that can be challenging for those that inhabit marine environments. There is therefore a demand for a framework through which to estimate energy expenditure from readily available data. We present the energetic costs associated with important time- and energy-intensive behaviours across nine families of marine bird (including seabirds, ducks, divers and grebes) and nine ecological guilds.

Significant Mitigation of Blast Overpressure Exposure During Training by Adjustment of Body Position as Demonstrated With Field Data.

Introduction: During training and deployment, service members (SMs) experience blast exposure, which may potentially negatively impact brain health in the short and long term. This article explores if blast exposure mitigation can be effectively achieved for four different weapon training scenarios that are being monitored as part of the CONQUER (COmbat and traiNing QUeryable Exposure/event Repository) program. The training scenarios considered here are a detonating cord linear (det linear) breaching charge, a water breaching charge, a shoulder-fired weapon, and a 120-mm mortar.

Experiencing restraint: A dialogic narrative inquiry from a service user perspective.

In recent decades concerns about violence and programs for the minimization of physical restraint, amongst other restrictive practices, have proliferated within mental health policy and practice. Whilst nurses are often called upon when violence occurs within mental health care settings, they often find themselves having the conflicting roles of caring and controlling. Within such situations it is service users, who are experts by experience, who perhaps can offer more meaningful insight into being restrained and thus provide a more appropriate approach in dealing with mental distress.

Dynamic monitoring of service members to quantify blast exposure levels during combat training using BlackBox Biometrics Blast Gauges: explosive breaching, shoulder-fired weapons, artillery, mortars, and 0.50 caliber guns.

CONQUER is a pilot blast monitoring program that monitors, quantifies, and reports to military units the training-related blast overpressure exposure of their service members. Overpressure exposure data are collected using the BlackBox Biometrics (B3) Blast Gauge System (BGS, generation 7) sensors mounted on the body during training. To date, the CONQUER program has recorded 450,000 gauge triggers on monitored service members.

Capturing, the experiences of undergraduate student nurses undertaking a pre-registration nursing degree course using an adapted experience based co-design approach.

Background: The quality of student experience in higher education plays an increasingly important role in attracting and retaining pre-registration nurses. Identifying and understanding the students' experiences of their course is a necessary step in the move towards improving the student experience. Experience Based Co-design (EBCD) is successfully established as an effective process for improving patient experience in a health care setting.

Alcohol and marijuana use predicting next-day absenteeism and engagement at school and work: A daily study of young adults.

This study examined effects of alcohol and marijuana use on next-day absenteeism and engagement at work and school among young adults (18-25 years old) who reported past-month alcohol use and simultaneous alcohol and marijuana use. Participants completed twice daily surveys for five, 14-day bursts. The analytic sample was 409 [64 % were enrolled in university (N = 263) and 95 % were employed (N = 387) in at least one burst].

Blood-Based Biomarkers of Repetitive, Subconcussive Blast Overpressure Exposure in the Training Environment: A Pilot Study.

Because of their unknown long-term effects, repeated mild traumatic brain injuries (TBIs), including the low, subconcussive ones, represent a specific challenge to healthcare systems. It has been hypothesized that they can have a cumulative effect, and they may cause molecular changes that can lead to chronic degenerative processes. Military personnel are especially vulnerable to consequences of subconcussive TBIs because their training involves repeated exposures to mild explosive blasts.

Modular Micro Raman Reader Instrument for Fast SERS-Based Detection of Biomarkers.

Sensitive detection of biomarkers is very critical in the diagnosis, management, and monitoring of diseases. Recent efforts have suggested that bioassays using surface-enhanced Raman scattering as a signal read-out strategy possess certain unique beneficial features in terms of sensitivity and low limits of detection which set this method apart from its counterparts such as fluorescence, phosphorescence, and radiolabeling. Surface-enhanced Raman scattering (SERS) has also emerged as an ideal choice for the development of multiplexed bioassays.

Perceived weight-related stigma, loneliness, and mental wellbeing during COVID-19 in people with obesity: A cross-sectional study from ten European countries.

Background: Increased weight-related stigma during the COVID-19 pandemic has amplified the need to minimise the impacts on mental wellbeing. We investigated the relationship between the perceived changes in the representation of obesity in the media and mental wellbeing during the pandemic in a sample of people with obesity across 10 European countries. We also investigated the potential moderating effect of loneliness.

Winter locations of red-throated divers from geolocation and feather isotope signatures.

Migratory species have geographically separate distributions during their annual cycle, and these areas can vary between populations and individuals. This can lead to differential stress levels being experienced across a species range. Gathering information on the areas used during the annual cycle of red-throated divers (RTDs; ) has become an increasingly pressing issue, as they are a species of concern when considering the effects of disturbance from offshore wind farms and the associated ship traffic.

A single introduction of wild rabbits triggered the biological invasion of Australia.

Biological invasions are a major cause of environmental and economic disruption. While ecological factors are key determinants of their success, the role of genetics has been more challenging to demonstrate. The colonization of Australia by the European rabbit is one of the most iconic and devastating biological invasions in recorded history.

Sign-tracking modulates reward-related neural activation to reward cues, but not reward feedback.

Research shows cognitive and neurobiological overlap between sign-tracking [value-modulated attentional capture (VMAC) by response-irrelevant, discrete cues] and maladaptive behaviour (e.g. substance abuse).

Alcohol and marijuana use, consequences, and perceived descriptive norms: Differences between two- and four-year college students.

Among two-year college students, alcohol and marijuana use, related consequences, and risk factors for use are not well understood. We examined differences between two- and four-year students in alcohol and marijuana use, consequences, and perceived descriptive norms, and explored whether two-year status moderated associations between norms and use. Data were drawn from a cross-sectional subsample of two- and four-year students aged 18-23 ( = 517) participating in a longitudinal study on alcohol use.

The role of perceived social norms in college student vaccine hesitancy: Implications for COVID-19 prevention strategies.

Among US adults, the highest rates of hesitancy to receive the COVID-19 vaccine are among young adults aged 18 to 25. Vaccine hesitancy is particularly concerning among young adults in college, where social interactions on densely populated campuses can lead to substantial community spread. Given that many colleges have opted not to mandate vaccines, identification of modifiable predictors of vaccine hesitancy - such as perceived social norms - is key to informing interventions to promote vaccine uptake.
