In Davis Strait, one of two primary Arctic gateways between the Arctic and Atlantic Oceans, the exchange between northward-flowing Atlantic waters and southward-flowing Arctic waters possibly influences deep-water formation in the subpolar North Atlantic. Yet, these circulation pathways and mixing processes, that may be changing, remain uncertain, underscoring the need for new tracers to resolve their structure and variability...
An exceptionally large blood O 2 store underlies the remarkable dive performance of elephant seals. However, elevated carboxyhemoglobin (COHb) concentrations in these seals complicate estimations of blood O 2 content and O 2 depletion rates, and may also affect monitoring of brain oxygenation in seals with new non-invasive near-infrared (NIR) recorders. Using hemoximetry analyses of blood samples during sleep apneas of juvenil...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
Development and validation of molecular biomarkers for the green‐lipped mussel ( Perna canaliculus )NARA Subscribed
Globally, there is a move towards using local, native species for ecotoxicological risk assessments. Anthropogenic stressors from urban, agricultural, and industrial activities can impact the health of receiving ecosystems. Biomarkers can provide valuable insights as early warning signals of the potential environmental impacts of stressors. The aim of this study was to develop biomarkers in the green‐lipped mussel ( Perna cana...
A framework to support the identification of critical habitat for wide-ranging species at risk under climate changeNARA Subscribed
To recover species at risk, it is necessary to identify habitat critical to their recovery. Challenges for species with large ranges (thousands of square kilometres) include delineating management unit boundaries within which habitat use differs from other units, along with assessing any differences among units in amounts of and threats to habitat over time. We developed a reproducible framework to support identification of cr...
Genomics‐informed conservation units reveal spatial variation in climate vulnerability in a migratory birdNARA Subscribed
Identifying genetic conservation units (CUs) in threatened species is critical for the preservation of adaptive capacity and evolutionary potential in the face of climate change. However, delineating CUs in highly mobile species remains a challenge due to high rates of gene flow and genetic signatures of isolation by distance. Even when CUs are delineated in highly mobile species, the CUs often lack key biological information...
Introduction Noise pollution is a major stressor in the marine environment; however, responses of economically and ecologically important invertebrates, such as oysters, are largely unknown. Methods Under laboratory conditions, we measured acute behavioral and physiological responses of eastern oysters ( Crassostrea virginica) to sound treatments mimicking human activity in the environment. Results Oysters immediately reduced...
Induction of metallothionein in the common bully ( Gobiomorphus cotidianus ) from the Motueka RiverNARA Subscribed
The Motueka catchment is a major river system in the South Island, New Zealand, typically considered to be of ‘good water quality’. The catchment has high metal inputs originating from a mineral belt in the headwaters. This study investigated the induction of metallothionein (MT) in the common bully, Gobiomorphus cotidianus , to assess exposure to trace metal contamination in the Motueka River. The results showed a significant...
DNA tandem repeats contribute to the genetic diversity of Brevibacterium aurantiacum phagesNARA Subscribed
Summary This report presents the characterization of the first virulent phages infecting Brevibacterium aurantiacum , a bacterial species used during the manufacture of surface‐ripened cheeses. These phages were also responsible for flavour and colour defects in surface‐ripened cheeses . Sixteen phages (out of 62 isolates) were selected for genome sequencing and comparative analyses. These cos‐type phages with a long non‐contr...
Trophic niche partitioning of dominant North‐Atlantic krill species, Meganyctiphanes norvegica , Thysanoessa inermis , and T. raschiiNARA Subscribed
Different krill species have a pivotal position in many marine food webs by both preying upon several trophic levels and being forage species for consumers. Within these food webs, different krill species coexist, though it remains unclear what mechanisms allow for the coexistence, for instance, of northern krill species in subarctic environments. Here, we hypothesize that the stable coexistence of sympatric krill species is b...
Motivation The Tundra Trait Team (TTT) database includes field‐based measurements of key traits related to plant form and function at multiple sites across the tundra biome. This dataset can be used to address theoretical questions about plant strategy and trade‐offs, trait–environment relationships and environmental filtering, and trait variation across spatial scales, to validate satellite data, and to inform Earth system mo...
