The return of sea otters to an estuary on the central Californian coast has significantly improved the health of seagrass, new research has found.
Seagrass was deemed to be heading for extinction in this region before the otters returned. Scientists found that the animals triggered a chain reaction of events that boosted the water-dwelling plants.
Two new studies show that ocean acidification is negatively affecting species and ecosystems, albeit to varying degrees. Acidification may also amplify global warming, according to a third study.
The oceans absorb more than a quarter of anthropogenic carbon dioxide emitted to the atmosphere. They form a natural store without which the Earth would now be a good deal warmer. But their storage capacities are limited and the absorption of carbon dioxide results in their acidification.
Warming oceans are causing marine species to change breeding times and shift homes with expected substantial consequences for the broader marine landscape, according to a new global study.
The three-year research project has shown widespread systemic shifts in measures such as distribution of species and phenology -- the timing of nature's calendar - on a scale comparable to or greater than those observed on land.
