Freshwater biodiversity in a rapidly changing Arctic: An expert horizon scan of key research questionsNARA Subscribed
Arctic freshwater biodiversity is rapidly changing due to climate warming, resource extraction, infrastructure development, and landscape transformation. To improve understanding, predict future responses, and inform policy formulation, research needs must be clearly identified. Using a horizon scan survey, Arctic freshwater experts from government, international agencies, and Indigenous Peoples identified 77 biodiversity rese...
Population‐specific bycatch risks in two vulnerable anadromous clupeids: Insights from otolith microchemistryNARA Subscribed
Otolith microchemistry analysis revealed that bycatch of European shads, allis shad Alosa alosa and twaite shad Alosa fallax , in western Iberian commercial fisheries removes individuals from a wide array of natal origins, with the most abundant source rivers suffering the heaviest losses. Spatial variation in bycatch risk was evident: Specific marine areas exhibited high natal origin diversity, reflecting complex dispersal. A...
Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream InvertebratesNARA Subscribed
For many Arctic rivers and streams, climate‐driven intensification of permafrost thaw slumping is a major source of disturbance to aquatic habitats. Thaw slumps are dynamic landforms that severely increase total suspended solids (TSS) and nutrients in downstream reaches and can persist over decades. Effects may differ in magnitude as slumps cycle through periods of higher and lower activity, with expansion of retrogressive slu...
Calcium Isotopes Correlate With Baleen Whale Feeding EcologyNARA Subscribed
Baleen whales are among the largest animals ever and engineer marine ecosystems by transporting nutrients both vertically through the water column and across vast oceanic distances. Hidden underwater, their feeding habits often remain unseen and hence must be studied indirectly based on stomach contents and stable isotopes. Here, we explore the potential of bone‐bound calcium isotopes as a chemical proxy for extant baleen whal...

Wildfire ash inhibits the growth and photosynthetic efficiency of marine phytoplanktonNARA Subscribed
While the ecological effects of wildfires have been documented in terrestrial and aquatic environments, impacts on coastal and ocean ecosystems are largely unexplored. Here, we describe the physical and chemical properties of ash from the CZU Lightning Complex fire (California, USA) and assess its experimental impacts on unicellular marine phytoplankton, using model monocultures. Air‐fall ash samples were primarily composed of...
What Predicts Gene Flow During Speciation? The Relative Roles of Time, Space, Morphology and ClimateNARA Subscribed
The processes that restrict gene flow between populations are fundamental to speciation. Here, we develop a simple framework for studying whether divergence in morphology, climatic niche, time and space contribute to reduced gene flow among populations and species. We apply this framework to a model system involving a clade of spiny lizards ( Sceloporus ) occurring mostly in northeastern Mexico, which show striking variation i...
Changes to virus taxonomy and the ICTV Statutes ratified by the International Committee on Taxonomy of Viruses (2024)NARA Subscribed
This article reports changes to virus taxonomy and taxon nomenclature that were approved and ratified by the International Committee on Taxonomy of Viruses (ICTV) in April 2024. The entire ICTV membership was invited to vote on 203 taxonomic proposals that had been approved by the ICTV Executive Committee (EC) in July 2023 at the 55th EC meeting in Jena, Germany, or in the second EC vote in November 2023. All proposals were ra...
Purpose To determine if post-exercise heart rate variability, in the form of logged transformed root mean square of successive differences of the R–R intervals (LnRMSSD) can be measured reliably during the recovery from a submaximal cycle test and what the relationship of LnRMSSD is with training status of the cyclists. Methods Fourteen male cyclists participated in the reliability part for the study, which included performing...
Projections of West African Monsoon (WAM) precipitation are uncertain. To address this, an improved understanding of the mechanisms driving WAM precipitation change is needed to shed light on inter-model differences and aid model development. The full forcing of increased CO 2 can be decomposed into different components such as the impact of ocean warming, or the direct radiative effect of increased CO 2 . This paper investiga...
Wastewater-based epidemiology (WBE) has been commonly used for monitoring SARS-CoV-2 outbreaks. As sampling times and methods (i.e. grab vs composite) may vary, diurnal changes of viral concentrations in sewage should be better understood. In this study, we collected untreated wastewater samples hourly for 4 days at two wastewater treatment plants in Wales to establish diurnal patterns in virus concentrations and the physico-c...
