Stable isotopes reveal that gelatinous zooplankton diets group by taxonomy and feeding traits in a coastal upwelling systemNARA Subscribed
Gelatinous zooplankton are abundant in marine ecosystems, yet their trophic roles and functional diversity in food webs have only recently gained attention. Gelatinous zooplankton taxa including hydromedusae, ctenophores, siphonophores, chaetognaths, and pelagic tunicates span multiple phyla and are often grouped taxonomically, but trait‐based categorizations have emerged as an ecologically meaningful alternative. Considering...
Pacific white shrimp ( Litopenaeus vannamei ) are among the most important aquaculture species but are highly susceptible to Vibrio infections. Novel disease management strategies are necessary. Previous studies have reported that peracetic acid (PAA) is an effective disinfectant, but its application in shrimp aquaculture remains underexplored. This study aimed to determine the median lethal concentration (LC 50 ) of PAA at tw...
Two new species of black coral are described herein: Leiopathes dumosa nov. sp. and Leiopathes brugleri nov. sp. Samples were collected between depths of 244 and 617 m on the North American continental slope between Texas and Florida, USA, and recognized in the family Leiopathidae Haeckel, 1896. L. dumosa nov. sp. is characterized by short stems and short branches forming bush-like colonies (usually less than 1 m tall and 0.25...
Functional diversity patterns have been thoroughly described for reef fishes across geographic gradients, but the effect of depth on these patterns remains largely unknown. Using diet, life-history, and behavioral traits, we evaluated the functional diversity of Caribbean reef-fishes from the surface to 450 m depth to test if taxonomically distinct communities along the reef slope are characterized by similar or distinct ecolo...
Small skeletal fossils associated with Archaeocyath reefs from the Xiannüdong Formation (Cambrian Series 2), southern Shaanxi, ChinaNARA Subscribed
Improved understanding of both the Small Skeletal Fossil (SSF) assemblages and archaeocyath reefs of the early Cambrian Period is important to best elucidate the evolution of early marine ecosystems during the Cambrian Radiation. To address this issue, we investigate the well-preserved SSF fauna associated with archaeocyaths of the early Cambrian Xiannüdong Formation (Dayingcun Section, Nanzheng area, southern Shaanxi). The Xi...
Rationale Acute alcohol intoxication impairs cognitive and motor control, elevating risk in safety–critical contexts. While blood alcohol concentration (BAC) quantifies exposure, it does not reflect real-time functional impairment. Mobile, performance-based assessments may offer scalable detection tools, but their sensitivity under controlled alcohol challenge requires further validation. Objectives To evaluate the sensitivity...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Accurate and precise age determination is essential for estimating key life-history parameters in fishes. Recent studies suggest that some fisheries management metrics, such as mortality, may be robust to biased age estimates. Thus, it can be more important to identify the most precise structure for age assignment. However, precision can vary geographically, highlighting the need for location-specific evaluations. Smallmouth b...
