To survive the open ocean, tiny fish larvae, freshly hatched from eggs, must find food, avoid predators, and navigate ocean currents to their adult habitats. But what the larvae of most marine species experience during these great ocean odysseys has long been a mystery, until now.
A team of scientists from NOAA s Pacific Islands Fisheries Science Center, the University of Hawai i (UH) at Mānoa, Arizona State University and elsewhere have discovered that a diverse array of marine animals find refuge in so-called surface slicks in Hawai i. These ocean features create a superhighway of nursery habitat for more than 100 species of commercially and ecologi

A LOCAL authority responsible for one of Britain’s most rural areas looks set to launch an intensive campaign to educate people about the dangers of releasing sky lanterns and helium balloons. North Yorkshire County Council is also set to lobby MPs and one of its former members – Education Secretary Gavin Williamson – to ensure every child is taught about the potentially deadly flying objects after concluding localised bans would have limited effects. An inquiry of the authority’s partnerships scrutiny committee heard how action was urgently needed as farmers were regularly seeing their animals suffer appalling deaths after ingesting the balloons or wires from the lanterns.
