Quantum of fear: Herbivore grazing rates not affected by reef shark presence Mar. Environ. Res. (IF 3.3) Pub Date : 2024-03-11 Sterling B. Tebbett, Sasha I. Faul, David R. Bellwood
Grazing by nominally herbivorous fishes is widely recognised as a critical ecosystem function on coral reefs. However, several studies have suggested that herbivory is reduced in the presence of predators, especially sharks. Nevertheless, the effects of shark presence on grazing, under natural settings, remains poorly resolved. Using ∼200 h of video footage, we quantify the extent of direct disturbance

Competition between ocean thermal structure and tropical cyclone characteristics modulates ocean environmental responses in the Yellow and Bohai Seas Mar. Environ. Res. (IF 3.3) Pub Date : 2024-03-10 Xiuting Wang, Jiagen Li, Liang Sun, Mengyuan Xu, Haihua Liu, Rui Liu
To study the environmental responses of tropical cyclones (TCs) in continental shelf regions, TCs passing over the Yellow Sea and Bohai Sea (YBS) during 2002–2020 were investigated, with a special focus on how competition between ocean thermal structure and TC characteristics modulates ocean surface changes. The spatial distributions of the climatic mixed layer depth (MLD), accumulated wind forcing
