Where are small marine animals most vulnerable to getting eaten? In a new study published in Proceedings of the National Academy of Sciences Oct. 26, scientists sketched the first global "BiteMap" showing where the ocean's mid-sized predators are most active. By fishing with dried squid baits called "squid pops," they discovered rising temperatures can shape entire communities of predators and have potential impacts lower down the food web.
Study using biomimetic fish-like robots shows that swimming closely together offers fish hydrodynamic benefits - research project with participation from University of Konstanz researchers provides first experimental validation of an answer to an old question.
Marine fish species are migratory in nature and not respectful of human-made territorial boundaries, which represents a challenge for fisheries management as policies tend to focus at the national level. With an average catch of 48 million tonnes per year, and USD $77 billion in annual fishing revenue, these species support critical fisheries, and require international cooperation to manage.
Mussels, barnacles, and snails are declining in the Gulf of Maine, according to a new paper by biologists Peter Petraitis of the University of Pennsylvania and Steve Dudgeon of California State University, Northridge. Their 20-year dataset reveals that the populations' steady dwindling matches up with the effects of climate change on the region.
The latest report from the Living Oceans Foundation finds Palau's reefs had the highest coral cover observed on the Global Reef Expedition--the largest coral reef survey and mapping expedition in history. Published today, the Global Reef Expedition: The Republic of Palau Final Report summarizes the Foundation's research on the status of coral reefs and reef fish in Palau and provides conservation recommendations that can help preserve these outstanding coral reefs for generations to come.
For recreational fishing enthusiasts, the thrill of snagging their next catch comes with discovering what's hooked on the end of the line. In many freshwater streams and rivers -- across the central and eastern parts of the U.S. -- anglers are often catching a popular freshwater game fish: the smallmouth bass. Now, scientists have discovered a new level of biodiversity within that species.
A new University of Washington and NOAA Fisheries study found that sea lions have the largest negative effect on early-arriving endangered Chinook salmon in the lower Columbia River. The results of this study will publish Oct. 18, 2020 in the Journal of Applied Ecology.
The number of sea turtles spotted along the coasts of the UK and Ireland has declined in recent years, researchers say.
Although the krill catch is regulated, caution is required to avoid endangering the population itself and the species that depend on it, warns a group of krill experts headed by Prof. Dr. Bettina Meyer from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) in the journal Communications Earth & Environment - Nature.
Researchers from The University of Hong Kong's School of Biological Sciences and The Swire Institute of Marine Science, have for the first time investigated the historical presence of coral communities in the Greater Bay Area, revealing a catastrophic range collapse and loss of diversity that occurred in the last several decades.
