Regional and context-specific approaches can improve marine heat wave research
Ocean heat waves can encourage predators and prey to migrate to areas where researchers do not expect to find them. It can also lead to biological changes in some species. Credit: Nunosa, Woods Hole Marine Facilities Ocean heat waves can create chaos in marine ecosystems and destroy coastal economies. In recent years, they have made headlines to fuel the storm…

Marine animals ingest microplastic particles and excrete them in their feces, posing a risk to the marine environment
Professor Schenker on a research dive. Credit: Dr. Tom Schlesinger. A new study from Tel Aviv University reveals alarming findings about the spread of microplastic particles in marine food webs. In recent years, numerous studies have investigated the dangers of marine animals, and more specifically filter feeders, ingesting non-degradable microplastic particles. In this study, the researchers sought to understand how…
