Impact of Elevated Suspended Sediment on the Physiology of the Temperate Sponge Suberites australiensisNARA Subscribed
Suspended sediment (SS) is a major stressor to coastal marine ecosystems worldwide, with SS loads expected to increase under future anthropogenic and climatic pressures. Sponges, as obligate filter feeders, are often assumed to be sensitive to elevated SS, yet responses vary widely among species, and little is known about physiological impacts of SS. Here, we examined the response of the abundant temperate sponge Suberites aus...
Mapping the Distribution and Conservation Status of Mature and Old Growth Forests Across Coastal Alaska and British ColumbiaNARA Subscribed
Old growth forests in coastal Alaska and British Columbia represent some of the most expansive temperate rainforests on Earth, supporting high biodiversity, substantial carbon stocks, and the cultural heritage of Indigenous communities. Despite their importance, spatially consistent information on the distribution of old growth and mature forests in this region remains limited. We addressed this gap by integrating data across...
With over half of people with HIV (PWH) in the U.S. entering older adulthood, identifying markers to distinguish Alzheimer’s disease (AD) and its precursor, amnestic mild cognitive impairment (aMCI), from other forms of neurocognitive impairment among PWH is urgent. We examined how HIV and aMCI status relate to AD CSF biomarkers in adult PWH and people without HIV (PWoH) characterized for aMCI. We included 80 PWH from the Nati...
Seabed‐contact activities operating in the deep sea can generate sediment plumes that pose varying levels of threat to benthic fauna. Corals are important components of deep‐sea ecosystems and can be particularly sensitive to elevated suspended sediment concentrations. In this study, we exposed colony fragments of the New Zealand deep‐sea scleractinian Goniocorella dumosa to four‐day pulses of four target sediment concentratio...
Muscle fat infiltration (i.e., myosteatosis) is an important index of muscle health and pathology in disease states, such as chronic liver disease (CLD). However, it is unknown whether myosteatosis differs due to anatomical location. Further, the mechanistic implications of divergent intermuscular adipose tissue (IMAT) deposition remain unknown in patients with CLD. Thirty-three patients with CLD (55.0 ± 10.5 years) and 17 hea...
