Regional oceanographic controls on water column nitrogen fixation in northern Australian watersOA Marine
Large blooms of the diazotrophic cyanobacteria, Trichodesmium , have been reported along the north coast of Australia and are readily evident in remote sensing images. During a research cruise in November 1999, we sampled from Townsville to Broome, examined Trichodesmium population densities and their rates of carbon and N 2 fixation alongside microscopy-based cell counts of them and other cyanobacterial diazotrophs. Additiona...
Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Precision oncology in non-small cell lung cancer (NSCLC) depends on biomarker testing and access to targeted therapies. However, disparities in testing and treatment highlight critical educational needs for patients, providers, and health systems. Using the NIH All of Us Research Program (2017–2022), we identified 287 patients with advanced NSCLC who received first-line carboplatin-based chemotherapy or targeted therapy. Socia...
Global Patterns and Drivers of Seagrass Biomass, Net Primary Production and Meadow StructureNARA Subscribed
Aim We decipher global patterns in seagrass growth and structure to advance seagrass science, facilitate multidisciplinary research, and promote effective management strategies and policy development for seagrass habitats. Location: Global. Time period: 1975 to 2024. Major taxa studied: Seagrasses—marine angiosperms. Methods A global data set on seagrass total biomass, total net primary productivity (NPP), shoot density, and p...
Seagrasses have been entwined with human culture for millennia, constituting a natural resource that has supported humanity throughout this history. Understanding the societal value of seagrass fosters appreciation of these ecosystems, encouraging conservation and restoration actions to counteract historic and predicted losses. This study overviews the plethora of seagrass use in human history, ranging from spiritual and cerem...
Marsh vegetation dampens wave energy, providing protection to coastal communities from storms. A new modeling framework was applied to study wave height evolution over the saltmarsh bordering Newbury, MA. A regional Delft3D hydrodynamic model generated wind driver waves in the open water portions of the study area, which were then one-way coupled with an analytical model, the Marsh Transect Wave Attenuation (MTWA) model, which...
Coverage matters: identifying and mitigating sampling frame issues in recreational fishing surveysNARA Subscribed
Surveys play an integral part in monitoring and maintaining sustainable recreational fisheries. For any probabilistic survey, the selection of a sampling frame (e.g., list of individuals or fishers) is an important decision because it influences the ability to provide unbiased estimates of recreational catch and effort. Undercoverage occurs when units of the target population (i.e., the population of interest) are missing from...
