For decades, climate scientists have tried to explain why ice-age cycles became longer and more intense about 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles.Read more
The islands and atolls (Ducie, Henderson, Oeno, and Pitcairn) are situated in the central South Pacific, thousands of miles from any continent, halfway between New Zealand and South America.Read more
A mysterious disease affecting sea stars has erupted along the Oregon coast. Sea star wasting syndrome causes the creature’s body to disintegrate, ultimately leading to death.Read more
A core migratory corridor of 1,150 km length and 30,800 km2 area was defined, of which 52% fell within 11 reserves.Read more
Macroalgae are the dominant habitat-forming organisms on temperate coastlines, providing habitat and food to entire communities.
In recent decades, there has been a decline in macroalgal cover along some urbanised shorelines, leading to a shift from diverse algal forests to more simple turf algae or barren habitats.
Along the urban shores of Sydney, its disappearance is coincident with heavy sewage outfall discharges along the metropolitan coast during 1970s and 1980s. Despite significant improvements in water-quality since that time, Phyllospora has not re-established.Read more
When designing terrestrial protected areas, the key is to consider not only how much they benefit terrestrial biodiversity but also how much they benefit coral reef ecosystemsRead more
Coral reefs are damaged by natural disturbances and local and global anthropogenic stresses such as global warming and ocean acidification. As stresses intensify, so do debates about whether reefs will recover after significant damage.Read more
Imagine swimming through a 50,000-year-old primeval forest. That's what happened to Ben Raines off the coast of Alabama. After hearing tales of a spot replete with fish and wildlife, Raines dove in and discovered masses of ancient bald cypress trees 60 feet below the surface. He says the stumps are as big as trucks and that the trees are so well-preserved that they still smell like fresh cypress sap when they're cut. The 0.5-square-mile forest was probably preserved in an oxygen-free environment under ocean sediment until Hurricane Katrina rolled in and uncovered it in 2005.Read more
A genetically modified strain of Salmon which have been engineered with extra genes to make them grow more quickly, pass on this trait to the hybrid offspring, researchers from Memorial University of Newfoundland, Canada, has found.Read more
Biosphere mixing appears to provide about one third the power required to bring the deep, cold waters of the world ocean to the surface, which in turn completes the ocean's conveyor belt circulation critical to the global climate system.Read more
Caffeine is found in many food and beverage products as well as some pharmaceuticals, and caffeine pollution is directly related to human activity (although many plant species produce caffeine, there are no natural sources of the substance in theRead more
