Reproductive and morphological traits distinguish early- and late-maturing Pacific lamprey (Entosphenus tridentatus)NARA Subscribed
Pacific lamprey, an anadromous fish native to the North Pacific Ocean, are imperiled in parts of their range. Many aspects of their biology are not fully understood, including the physiology of their spawning migration. Pacific lamprey exhibit two divergent reproductive life histories: early-maturing and late-maturing. Interior Columbia River early-maturing lamprey complete the final stages of gonadal maturation ~ 10 months af...
Coral mortality in a mass bleaching event influenced by proximity to diseased tissue and reef topographyNARA Subscribed
Coral reefs of the Florida Keys experienced the hottest summer on record in 2023, causing mass bleaching and mortality of scleractinian corals. Sea surface temperatures remained above 31°C for 41 days, exceeding all prior records for the region. Branching corals fared especially poorly, especially Acropora palmata , which has now been deemed functionally extinct across the entire Florida Reef Tract. High temperatures and prolo...
Predicting the ocean state in a reliable and interoperable way, while ensuring high-quality products, requires forecasting systems that synergistically combine science-based methodologies with advanced technologies for timely, user-oriented solutions. Achieving this objective necessitates the adoption of best practices when implementing ocean forecasting services, resulting in the proper design of system components and the cap...
Scientific advances in environmental data coverage and machine learning algorithms have improved the ability to make large‐scale predictions where data are missing. These advances allowed us to develop a spatially resolved proxy for predicting numbers of tropical nearshore marine taxa. A diverse marine environmental spatial database was used to model numbers of taxa from ∼1000 field sites, and the predictions were applied to a...
