Microplastics accumulation in freshwater organisms is expected to rise with the level of urbanization occurring near riverbanks, although other factors also contribute to this trend. Benthic macroinvertebrates, in particular, may be disproportionately affected by microplastic accumulation due to their feeding strategies (e.g., filter vs deposit feeders), highlighting feeding type-specific ingestion patterns. Nevertheless, it r...

Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are essential for conservation planning. Using the loggerhead turtle ( Caretta caretta )...

Experiments on entire ecosystems have contributed knowledge on effects of atmospheric CO 2 and climate change, environmental pollutants, trophic cascades, response of fisheries to management, consumer interactions, ecosystem resilience and stability, and early warning indicators of critical transitions in ecosystem state. Rate of change in external drivers of an ecosystem such as climate warming, inflow of water or nutrients,...

Objectives Physical activity is associated with reduced risk of prostate cancer (PCa) progression and death; changes in insulin sensitivity and inflammation are potential mediating mechanisms. This study examined whether exercise after PCa diagnosis affects insulin-related and inflammatory biomarkers. Methods The Active Surveillance Exercise (ASX) randomized controlled trial was assigned to men undergoing active surveillance f...

Purpose Identifying suspended-sediment (SS) sources, seasonal variability, and phosphorus (P) transported with SS is critical information for basin managers, although there may be concerns about comparability between flow-integrated SS samples used for sediment fingerprinting and discrete samples used for concentrations and loads in basins where SS is mostly silt + clay and(or) one land-use predominates. Objectives were to det...

Pleural effusion (PE) is a common clinical manifestation associated with advanced stages of both malignant and non-malignant diseases. PE frequently occurs in advanced non-small cell lung cancer (NSCLC) and contributes to tumor progression. NSCLC accounts for more than 85% of the lung cancers and remains a problem worldwide due to its late diagnosis and low rate of response to treatment. Extracellular vesicles (EVs) present in...

Multiple-use conflicts of the marine benthos (“bottom-use conflicts”) are increasing as humans expand use of the coastal zone. These conflicts necessitate balanced policies that consider the economic and ecological benefits of different bottom uses. In the Virginia coastal lagoons on the US east coast, there is a potential bottom-use conflict between hard clam ( Mercenaria mercenaria ) aquaculture and seagrass ( Zostera marina...

In the shift toward sustainable energy production, offshore wind power has experienced notable expansion. Several projects to install floating offshore wind farms in European waters, ranging from a few to hundreds of turbines, are currently in the planning stage. The underwater operational sound generated by these floating turbines has the potential to affect marine ecosystems, although the extent of this impact remains undere...

Between 2012 and 2022, the Vancouver Aquarium Marine Mammal Rescue Centre sedated 110 harbor seal pups for physical examinations, diagnostic procedures, or treatment. A sedation protocol of butorphanol and midazolam (0.1–0.2 mg/kg each) was administered via a single i.v. injection in 171 procedures. Of these, 21 pups were anesthetized only with the injectables, while supplemental isoflurane inhalation anesthesia by mask was pr...
