Introduction Understanding migration timing and movement behavior is critical for predicting population responses to environmental changes. The beluga whale ( Delphinapterus leucas ) population in Cumberland Sound, Nunavut, is currently endangered due to historical and ongoing overharvesting. Methods By comparing satellite telemetry data from two distinct time periods (1998–1999 and 2006–2008), we evaluated beluga whale dive b...
Although plasma pTau181 has been shown to accurately discriminate patients with Alzheimer’s disease from healthy older adults, there are few studies of plasma biomarkers among middle-aged populations. Given the potential utility of plasma AD biomarkers such as pTau181 in screening for disease risk, examining pTau181 in a middle-aged cohort without AD is important for future implementation. The objectives of this study were to...
Comparison of Six Data Cleaning Methods for Determining Repetitive Head Impact Exposure in Youth Tackle FootballNARA Subscribed
Purpose Instrumented mouthguards (iMGs) are commonly used to quantify head acceleration event (HAE) exposure, but accurate interpretation requires rigorous data cleaning methods. This study compared six data cleaning methods for determining HAE rates and magnitudes, as well as cleaning method validity compared to the 5 th method video verification in youth tackle football. Methods Fifty athletes (ages 8-12) wore Impact Monitor...
We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee ( Oncorhynchus nerka ) at a given level of abundance by increasing the availability of Daphnia , an important food source. Age‐specific size (length, weight, and relative weight) and biomass were compared for periods with and without N addition....
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Mineral Resource Disclosure with Probabilistic ModelsNARA Subscribed
Geological variability at all scales and sparse sampling make Mineral Resource uncertainty an inevitable reality for mining companies and the concerned public. The workflow for probabilistic resource modeling is established, providing accurate and precise estimates of uncertainty in local and global resources. Companies that adopt standard probabilistic resource modeling practices across assets have powerful information for ri...

Seasonal occurrence and condition of leopard seals at an extralimital Sub-Antarctic IslandNARA Subscribed
Leopard seals ( Hydrurga leptonyx ) occur mainly south of the Antarctic Polar Front, but immatures, in particular, seasonally move beyond this range during the austral winter and spring, typically under increased sea ice conditions. Extralimital occurrences of leopard seals can be observed at several sub-Antarctic islands where they haul out to rest. We present new records of leopard seal sightings at Marion Island, southern I...
Ultraconserved Elements Reveal the Relationship Between Facultative Keratinophagy and Synanthropic Evolution in Clothes MothsNARA Subscribed
Synanthropic species live in close association with, or benefit from, humans. Despite their potential impacts to human health, little is known about the mechanisms driving synanthropic life‐history evolution, evolutionary forces shaping diet among synanthropes, or how these combined factors affect population dynamics and/or speciation. The Tineidae moth family contains several synanthropic species, including the globally distr...
Recreational fishing surveys have an important role in providing data to inform fisheries management. The selection of a contact method is an important and often challenging consideration that influences the potential for non‐sampling errors that can result in unrepresentative data and biased estimates. Telephones are used for many off‐site recreational fishing surveys, but widespread use of digital technology suggests that on...
● This abstract summarizes the results of two expert consultations conducted to gather insights into effective communication and engagement strategies in recreational fisheries. ● Effective science communication fosters knowledge, understanding, and trust in both science and management decisions. ● Public involvement and stakeholder engagement are essential for effective management. ● Simplifying complex research findings and...
The purpose of this study was to investigate the effects of acute nitrate (NO 3 − )-rich beetroot juice ingestion on explosive and high-intensity exercise performance, oral microbiota composition, and cognitive flexibility (i.e., function), before and after maximal intermittent running exercise. Fifteen women team-sport athletes were assigned in a randomized, double-blind, crossover design to consume concentrated NO 3 – -deple...
Does visual or mechanosensory disruption influence risk assessment in coral reef fishes: a preliminary studyNARA Subscribed
Interpreting and responding to environmental cues from different modalities has survival value. In fish, the role of multimodal perception has been studied in regard to both foraging and risk assessment, with modalities including vision, olfaction, and mechanoreception via lateral lines. We studied reef fish boldness by placing novel objects that obstructed vision, lateral line use, or both into a coral reef environment with n...
