Structural complexity drives taxonomic and functional diversity in kelp holdfast communitiesNARA Subscribed
Kelp holdfasts form dense 3D habitat that supports diverse biological communities, but the relative importance of different structural components and the methods used to measure them are poorly understood. Here, we compare multiple 3D imaging approaches spanning different levels of cost and accessibility including CT scanning, photogrammetry and depth sensing, to quantify the structural complexity of holdfasts in the kelp Eckl...
Case study: Applying the resist–accept–direct framework to an Ojibwe Tribe's relationship with the natural worldNARA Subscribed
Ojibwe Tribes' approach to the natural world is guided by the original treaties between beings (species and spirits) and the Ojibwe people who reside in lands now known as the United States and Canada. Relationships with these beings, such as ogaa (walleye Sander vitreus ), are best characterised as taking care of a relative/gift for the next seven generations of Ojibwe. Initial denial of treaty rights by the state government...
Japanese Hops ( Humulus japonicus ) Control and Management Strategies in Large River FloodplainsNARA Subscribed
Japanese hops (Humulus japonicus) is an invasive vine that establishes in open areas in riverine habitats and suppresses tree regeneration and native vegetation. This study evaluated the use of herbicides and tree plantings to control and manage Japanese hops on five Mississippi River islands over a four-year period. Herbicide treatments included a preemergent (sulfometuron methyl), a postemergent (glyphosate), and a combinati...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Ongoing scientific programs that monitor marine environmental and ecological systems and changes comprise an informal but collaborative, information-rich, and spatially extensive network for the Alaskan Arctic continental shelves. Such programs reflect contributions and priorities of regional, national, and international funding agencies, as well as private donors and communities. These science programs are operated by a varie...
Marine recreational fishing ( MRF ) is a high‐participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative requirement, estimates are only available for some countries. Here, data on numbers of fishers, participation rates, days fished, expenditures, and catches of two widely targeted species were synthesized to...
Mechanisms of subzero growth in the cryophile Planococcus halocryophilus determined through proteomic analysisNARA Subscribed
Summary The eurypsychrophilic bacterium Planococcus halocryophilus is capable of growth down to −15°C, making it ideal for studying adaptations to subzero growth. To increase our understanding of the mechanisms and pathways important for subzero growth, we performed proteomics on P . halocryophilus grown at 23°C, 23°C with 12% w/v NaCl and −10°C with 12% w/v NaCl. Many proteins with increased abundances at −10°C versus 23°C al...
