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...
Diet affects arctic ground squirrel gut microbial metatranscriptome independent of community structureNARA Subscribed
Summary We examined the effect of diet on pre‐hibernation fattening and the gut microbiota of captive arctic ground squirrels ( Urocitellus parryii ). We measured body composition across time and gut microbiota density, diversity and function prior to and after five‐weeks on control, high‐fat, low‐fat (18%, 40% and 10% energy from fat, respectively), or restricted calorie (50% of control) diets. Squirrels fattened at the same...
Multi‐proxy study of Holocene environmental change and human activity in the Central Apennine Mountains, ItalyNARA Subscribed
This paper describes a multi‐proxy palaeoecological investigation undertaken in conjunction with an archaeological survey of the Upper Sangro Valley in the Abruzzo National Park, Central Italy. Despite being a biodiversity hotspot and regarded as a near‐pristine area, the pollen, spore and diatom data all show major changes in the vegetation extending to over 2000 m a.s.l. during the mid to late Holocene. Although there are ch...
Response of freshwater microcosm communities to nutrients, fish, and elevated temperature during winter and summerNARA Subscribed
Under conditions of stress, shallow freshwater ecosystems can undergo a state change characterized by the rapid loss of macrophytes and subsequent dominance of phytoplankton. Elevated water temperature may promote such change. Here we report the impact of two warming regimes (continuous 3°C above ambient and 3°C above ambient during summer only), with two nutrient loadings and the presence or absence of fish, on 48 microcosm e...
Late Holocene (ca. 4 ka) marine and terrestrial environmental change in Reykjarfjördur, north Iceland: climate and/or settlement?NARA Subscribed
Core B997‐328PC is from the landward side of a 100‐m‐deep basin in Reykjarfjördur, a small fjord on the north coast of the northwest peninsula of Iceland. This is an area that can be severely affected by incursions of polar sea‐ice but has not suffered marked land erosion during the Settlement period. The core is 422 cm in length and consists principally of fine‐grained muds with in situ molluscs. Eleven AMS 14 C dates on moll...
