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...
Indirect effects of invasive predators on litter decomposition and nutrient resorption on seabird‐dominated islandsNARA Subscribed
Despite recent interest in the ecosystem impacts of invasive aboveground organisms, most work in this area has focused on effects of invasive plants, and the effects of invasive herbivores and predators remain poorly understood. We studied 18 forested, offshore islands in northern New Zealand. Nine of these host high densities of burrowing seabirds that serve as ecosystem drivers by transporting nutrients from the ocean to lan...
Above‐ and below‐ground impacts of introduced predators in seabird‐dominated island ecosystemsNARA Subscribed
Predators often exert multi‐trophic cascading effects in terrestrial ecosystems. However, how such predation may indirectly impact interactions between above‐ and below‐ground biota is poorly understood, despite the functional importance of these interactions. Comparison of rat‐free and rat‐invaded offshore islands in New Zealand revealed that predation of seabirds by introduced rats reduced forest soil fertility by disrupting...
