Accelerated carbon cycling after 50 years of warming and increasing hydrologic variability in a temperate streamNARA Subscribed
Rivers transform and transport much of the organic input they receive from terrestrial ecosystems. This carbon sustains stream food webs and fuels the production and release of carbon dioxide and methane to the atmosphere. Warming water temperatures and intensification of the hydrologic cycle due to climate change are likely to affect these carbon transformations and downstream transport in streams. Here, we examine the natura...
Algal assemblage drives patterns in ecosystem structure but not metabolism in a productive riverNARA Subscribed
Algal dynamics are fundamental drivers of lotic ecosystem processes. Although rivers tend to be heterotrophic and have low standing stocks of autotrophic biomass, filamentous algae can cause nuisance algal blooms that alter the structure of the autotrophic assemblage. Still, the influence of these blooms on ecosystem processes can be variable. Here, we examined the structural and functional contribution of filamentous and epil...
Combining fish tracking methods is a promising way of leveraging the strengths of each approach while mitigating their individual weaknesses. Acoustic telemetry provides presence information as the fish move within receiver range, eliminating the need for tag recovery. Archival tags, on the other hand, record environmental variables on tag retrieval, enabling continuous path reconstruction of a fish beyond coastal regions. Thi...
Nutrient dynamics, carbon storage and community composition on artificial and natural reefs in Bali, IndonesiaNARA Subscribed
Artificial reefs are now commonly used as a tool to restore degraded coral reefs and have a proven potential to enhance biodiversity. Despite this, there is currently a limited understanding of ecosystem functioning on artificial reefs, and how this compares to natural reefs. We used water sampling (bottom water sampling and pore water sampling), as well as surface sediment sampling and sediment traps, to examine the storage o...
Artificial coastal structures (ACSs) are primarily designed to provide services for human use, such as flood defence or shipping, and are generally poor for marine biodiversity. Consequently, there has been significant research effort to enhance these hard structures to increase biodiversity and habitat availability via eco-engineering. On seawalls and breakwaters, this has included the creation of habitats for benthic species...
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...
Purpose of Review Disasters are becoming more common and challenge national and global resiliency and response efforts. As a result, government agencies have increased interest in disaster research to understand their environmental impact and health-related consequences. With the research field greatly expanding, Institutional Review Boards (IRBs) are being asked to review research protocols aimed at assessing health risks, ex...
Temporal and spatial variation in adult and juvenile mobile fauna associated with natural and artificial coastal habitatsNARA Subscribed
Coastal habitats are important for commercially exploited and protected species of fish and larger mobile invertebrates. The addition of artificial structures within the marine environment has the potential to alter the connectivity between habitats and to affect metapopulations of a region. Baited remote underwater videos (BRUV) were used to investigate the spatial and seasonal variation in abundance of adult and juvenile mob...
