An empirical ridge statistic that correlates weekly level ice thickness with keel depth and weekly number of ridges was investigated using upward looking sonars (ULS) data from 2006 to 2020 in the Fram Strait. The applied methodology was similar to the previous studies for the Beaufort Sea. The data were divided into weekly segments. For each of them, level ice thickness (hi), the number of ridges (N) and the average (hk) and...
Coastal systems are vital to human societies, delivering numerous ecosystem services. However, human activities introduce contaminants, especially trace metals (TM) that contribute to their degradation. These environments are inherently dynamic and complex, characterized by rapidly occurring biogeochemical processes. As a consequence, high-frequency sampling is required to evaluate short-term TM dynamics. The hourly temporal v...
Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership of scientists and practitioners called the Shorebird Science and Conservation Collec...
Do lactating ewes guide lambs to their teats by smell? Perinatal change in inguinal wax composition and lambs’ reaction to itNARA Subscribed
Amongst the array of sensory cues maternal ewes provide to their lambs, the role of odors still remains unclear in Ovis aries . Specifically, the communicatory potential on lambs of the scent released by the ewes’ perimammary inguinal glands is little studied. It is thus worthy to increase our insight about the adaptive value of ovine inguinal glands, the chemical nature of their secretion (i.e., inguinal wax, IW) and their co...
Water quality of spawning grounds constrains the population dynamics of an emblematic diadromous species (Alosa alosa)NARA Subscribed
In this study, the role of water quality has been studied to assess its suitability for the allis shad ( Alosa alosa ), a diadromous fish for which abundance has drastically declined at the beginning of 2000 and is remaining critically low in the Garonne basin (France). The water quality regarding contamination at spawning grounds and its toxicity for embryos and larvae is one possible explanatory factor for this decline, whic...
Levels of dissolved oxygen in open ocean and coastal waters are decreasing (ocean deoxygenation), with poorly understood effects on marine megafauna. All of the more than 1000 species of elasmobranchs (sharks, skates, and rays) are obligate water breathers, with a variety of life‐history strategies and oxygen requirements. This review demonstrates that although many elasmobranchs typically avoid hypoxic water, they also appear...
Whole blood transcriptome signature predicts severe forms of COVID-19: Results from the COVIDeF cohort studyNARA Subscribed
COVID-19 is associated with heterogeneous outcome. Early identification of a severe progression of the disease is essential to properly manage the patients and improve their outcome. Biomarkers reflecting an increased inflammatory response, as well as individual features including advanced age, male gender, and pre-existing comorbidities, are risk factors of severe COVID-19. Yet, these features show limited accuracy for outcom...
Comparison of active measurements, lichen biomonitoring, and passive sampling for atmospheric mercury monitoringNARA Subscribed
The number of atmospheric mercury (Hg) monitoring stations is growing globally. However, there are still many regions and locations where Hg monitoring is limited or non-existent. Expansion of the atmospheric Hg monitoring network could be facilitated by the use of cost-effective monitoring methods. As such, biomonitoring and passive monitoring offer a unique alternative to well-established monitoring by active measurements, s...
