Speciation of European bullheads ( Cottus spp.): The next problem for taxonomy of northern freshwater fishesNARA Subscribed
High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from previous generations of molecular studies, a dearth of next‐generation sequencing tools for...
Expert consensus on passive heating interventions to promote skeletal muscle strength and mass: a delphi studyNARA Subscribed
Purpose Passive heating has emerged as a potential non‑exercise method to support muscle strength and mass, but its application is limited by inconsistent protocols and unclear dosage and safety guidelines. This study used a Delphi methodology to establish expert consensus on key parameters for passive heating interventions targeting neuromuscular and muscle morphology outcomes. Methods An international panel of academic exper...
The aetiology of frailty remains unknown. It has been hypothesised that individual differences in epigenetic mechanisms, particularly DNA methylation (DNAm), may help to explain why some individuals become frail while others do not. Relating epigenetic measures to transitions in age-related frailty in individual patients requires longitudinal studies over many years. To overcome this barrier, we study associations between DNAm...
Calls for equity and justice are increasingly shaping ocean and coastal governance; however, a persistent challenge remains in centering how Indigenous Peoples’ and Local Communities’ (IPLCs) values are meaningfully recognized and enacted within decision-making processes, particularly under accelerating socioecological change. This review synthesizes interdisciplinary scholarship to examine how IPLCs mobilize their knowledge,...
Species diversity and competition influence nitrogen resorption efficiency in mixed hardwood plantationsNARA Subscribed
Nutrient dynamics substantially influences forest productivity, yet the influence of competition on these processes in forests is not well understood. Nitrogen is an important limiting nutrient for tree growth, but how canopy nitrogen dynamics are influenced by tree diversity and competition is unclear. Nitrogen-use efficiency is one mechanism suggested to support niche complementarity, promoting increased productivity as dive...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Exploring Marine Mammal Cognition as a Conservation ToolNARA Subscribed
Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities. Large‐brained, long‐lived animals such as marine mammals often have extensive capability to adaptively modify their behavior due to the...
Age-related change in skeletal muscle strength, size, and adiposity over 18 years in Caribbean menNARA Subscribed
Declines in muscle strength outpace declines in muscle mass with age, so factors like muscle adiposity (i.e., myosteatosis) may contribute to strength loss. We describe intermuscular adipose tissue (IMAT) and grip strength over 18 years among middle-aged and older African Caribbean men. We hypothesized that increases in IMAT precede the loss of muscle area and strength, and that increased IMAT is independently associated with...
Does acute stress induced via cold water immersion increase blood THC concentrations in regular cannabis users?NARA Subscribed
Rationale Δ 9 -tetrahydrocannabinol (THC), the principal intoxicant in cannabis, is a highly lipophilic substance that is readily stored in fat. Preclinical research suggests that fat-stored THC can be released into circulation under lipolytic conditions, such as stress. However, compelling evidence of this phenomenon is lacking in humans. Objectives Here, we investigated the effects of acute stress on blood (plasma) THC (and...
Quantifying the Potential of Argon Detection Capabilities for Nuclear Explosion MonitoringNARA Subscribed
Current noble gas detection systems for nuclear explosion monitoring are based on the detection of four radioxenon isotopes—Xe-131m, -133, -133m and -135. The data provided by radioxenon detection could be enhanced by other radionuclide signatures such as Ar-37. Activation of Ca-40 in rock by neutrons produces Ar-37, and monitoring for this additional nuclide could help distinguish detections of nuclear explosions from backgro...
A Participatory Decision-making Strategy for Geoconservation Implemented in Portland, JamaicaNARA Subscribed
Geoconservation aims to protect the legacy of the Earth, and an integral component is decision-making. Decisions in geoconservation impact residents and other stakeholders; therefore, strategies to facilitate participatory decision-making are needed. Here, we present a strategy to facilitate the implementation of the Analytic Hierarchy Process (AHP) with a diverse group of stakeholders in Portland, Jamaica, without previous ex...
