A closer look at “Ocean Warming and Herbivorous Fish Grazing Drive Kelp Forest Collapse Along Japan's Izu Pe”, exactly as the source publishes it. Kelp forests along Japan's Izu Peninsula are collapsing due to a combination of rising ocean temperatures and overgrazing by herbivorous fish, according to new research. These underwater forests, formed by large brown seaweeds, are critical habitats for numerous fish and invertebrates, and they play These underwater forests, formed by large brown seaweeds, are critical habitats for numerous fish and invertebrates, and they play a key role in coastal productivity and carbon cycling.
Yet across Japan, kelp forests have been declining, replaced by 'isoyake' – a phenomenon where rocky reefs become largely barren of large seaweeds. The study highlights how warming waters stress kelp, while expanding populations of grazing fish, such as rabbitfish and parrotfish, consume the weakened algae.
