Scientists have revealed that the northern Galapagos Islands of Darwin and Wolf are home to the largest shark biomass reported to date (12.4 tons per hectare).
Severe oxygen drops in the water can leave trails of fish kills in their wakes, but scientists thought adult fish would be more resilient to the second major threat in coastal waters: acidification.
Coral reefs around the world are in deep trouble.
"Ocean acidification is likely to progress along our coastline as a patchwork of hotspots," said researcher Kristy Kroeker.
Three species of shark, tiger, lemon and Caribbean reef, all use deeper coral reefs in the Virgin Islands, but only lemon shark presence was associated with seasonal grouper spawning aggregations, according to a new study.
How species genetically adapt to their environment is a central question related to the evolution of biodiversity. In a new study scientists at Uppsala University and their colleagues report that whole genome sequencing of Atlantic and Baltic herring revealed hundreds of loci underlying adaptati ...
By now, you've probably heard that at least 90 percent of the Great Barrier Reef has been affected by a global bleaching event. But these "rocks" on the seabed play a key role for life in oceans - and for people, too.
Antarctic regions are natural laboratories to study biodiversity and the impact of climate change. In Antarctica, some marine ecosystems are particularly vulnerable to the ocean acidification due to an excess of carbon dioxide released into the atmosphere.
A successful trial has been described of a new method of identifying the carbon uptake of specific marine bacterioplankton taxa.
The oceans are in bad shape. The high seas — like the moon, outer space and Antarctica — can’t be claimed by any nation.
21 April 2016 – International guidelines being developed by a United Nations agency and new technologies are expected to boost efforts to cut down levels of abandoned fish gear, which often continues to carry out the capture process, entangling fish and other marine animals in its nets, a phenom ...
Authorities are looking into whether pollution is to blame for a spate of mysterious mass fish deaths along the country’s central coast
Australian scientists said on Wednesday that just seven percent of the Great Barrier Reef, which attracts around A$5 billion ($3.90 billion) in tourism every year, has been untouched by mass bleaching that is likely to destroy half the coral.
CAIRNS, Australia, April 20 (UPI) -- Just 7 percent of the Great Barrier Reef has avoided bleaching. It's the worst coral bleaching event in Australia's history.
Australia’s world heritage site is the largest living thing on Earth. But warm water driven by El Niño is bleaching the reef, and a recent report calls for it to be listed as in danger
Singapore/Bangkok, 15 April 2015 - Guidance material on how recreational diving can protect fragile marine biodiversity threatened by growing coastal tourism and support the 2030 Agenda for Sustainable Development will be launched tomorrow at Asia's largest and oldest dive expo by the United Nat ...
Australia’s Great Barrier Reef is undergoing the most severe bleaching event in its history, as corals along the reef expel the symbiotic algae that provide them both with their rich colours and food.
A new study found that about 11 percent of adult loggerhead turtles were dying early in the waters off Middle East and North Africa due to entanglement in fishing nets used by small-scale fisheries.
DHAKA, Bangladesh, Apr 12 2016 (IPS) - Bangladesh has decided to set up a Hilsa Conservation Trust Fund (HCTF) to protect this fish from over-exploitation due to population growth and effects of climate change.
Approximately 2,500 miles east of Rio de Janeiro and just over 1,200 miles west of the African country of Angola, lies St. Helena Island: one of the most remote inhabited islands in the world.
A recent study shows that effective shark conservation in Indonesia only works when shark protection through no-fishing zones is combined with efforts to involve local communities in the management of their own fisheries and by providing alternatives to sustain their livelihoods.
It’s a deep-sea crab invasion. A unique video has captured a surprise swarm of red crabs on the sea floor at the Hannibal Bank seamount off the Pacific coast of Panama.
WOODS HOLE, Mass., April 6 (UPI) -- Surprisingly, some microbes thrive beneath ocean floor. For the first time, scientists have studied in detail the microbial community living inside dense, rocky crust under the ocean floor.
Thousands of loggerhead turtles are killed annually in areas of Syria, Libya and Egypt and Tunisia where they travel to find food
A new study has found that multiple stressors might be too much for corals. The findings have important implications for the resilience of coral reefs to climate change.
They might host habitats of huge ecological importance, but two-thirds of the world’s oceans lie beyond the authority of national governments
Plankton is the basis for the entire marine food web - and it is under threat. From the Mediterranean to the Pacific, animals have been struggling to survive, due apparently to changes with plankton.
A panel of scientists, convened in 2013 at the behest of government officials, has delivered their findings on the threat of ocean acidification to the North American West Coast. The danger is real, they say, but they see a path to progress.
CAPE TOWN, South Africa, Apr 4 2016 (IPS) - When Africa’s oldest protected marine area, Tsitsikamma — the largest in the world, incorporating 80 km of rocky coastline, bustling with marine life, much of it endangered — was opened as a pilot for public fishing on December 15, 2015, there was a bi ...
The world’s coral reefs face unprecedented threats. Their survival depends on how well they can cope with a long list of pressures including fishing, storms, coral bleaching, outbreaks of coral predators and reduced water quality.
The southern tip of Africa is washed by two oceans: the Indian and Atlantic oceans. This should allow South Africa to benefit economically from various activities through developing the ocean economy. Fisheries, tourism and maritime activities are some of the sectors that can underpin the economy.
