The recent widespread adoption of drones for studying marine animals provides opportunities deriving biological information from aerial imagery. large scale imagery data acquired is well suited machine learning (ML) analysis. Development ML models analyzing animal has followed the classical paradigm training, testing, and deploying a new model each dataset, requiring significant time, human effort, expertise. We introduce Frame Level ALIgment tRacking (FLAIR), which leverages video...
Abstract Reef fish assemblages are exposed to a wide range of anthropogenic threats as well chronic natural disturbances. In upwelling regions, for example, there is seasonal influx cool nutrient‐rich waters that may shape the structure and composition reef assemblages. Given climate change disrupt oceanographic processes by altering frequency strength disturbances, understanding how respond events essential effectively manage ecosystems under changing ocean conditions. This study used...
Long-distance movements associated with environmental and ecological drivers are common in a wide array of mobile marine species. Understanding such is particularly important for management conservation threatened species, which may be exposed to anthropogenic threats throughout their range. Pacific nurse sharks (Ginglymostoma unami) endangered because interactions fisheries lack biological knowledge as recently described Little known about this species’ its broad distribution the tropical...
Abstract Tiger sharks ( Galeocerdo cuvier ) play an important ecological role as top predators, yet knowledge of their reproductive ecology is scarce. Here, the authors report first observation a potential neonate G. at Cocos Island, predator‐dominated oceanic island in Eastern Tropical Pacific (ETP). The individual was detected using baited remote underwater video stations (BRUVS). cameras also female individuals potentially pregnant, suggesting that parturition may take place or near...
Abstract No-take marine protected areas (MPAs) can mitigate the effects of overfishing, climate change and habitat degradation, which are leading causes an unprecedented global biodiversity crisis. However, assessing effectiveness MPAs, especially in remote oceanic islands, be logistically challenging often restricted to relatively shallow accessible environments. Here, we used a long-term dataset (2010–2019) collected by DeepSee submersible Undersea Hunter Group that operates Isla del Coco...
