Biologist Mikhail Matz uses next-generation sequencers and a massive, NSF-supported supercomputer to study corals at the genomic level and look for evolutionary changes.
By examining 800,000-year-old polar ice, scientists increasingly are learning how the climate has changed since the last ice melt and that carbon dioxide has become more abundant in the Earth's atmosphere.
Droughts in the late 20th century rival some of North Africa's major droughts of centuries past, reveals new research that peers back in time to the year 1179.
An international team of marine biologists has found that existing diversity in some coral populations may significantly influence their response to extreme temperature disturbances â€” such as those predicted from climate warming.
Scientists may use fossilized coral reefs in the Great Barrier Reefs to understand how sea levels have changed over the past 20,000 years.
Ice Age climate records from an Arizona stalagmite link the Southwest's winter precipitation to temperatures in the North Atlantic.
Researchers spent two months this summer high in the Peruvian Andes and brought back two cores, the longest ever drilled from ice fields in the tropics.
An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change.
A U.S.-led scientific team has found a rare photosynthetic alga might be able to save certain colonies of coral from the damaging effects of global warming. The team, led by Pennsylvania State University Assistant Professor Todd LaJeunesse, evaluated corals -- and the photosynthetic algae that live inside their cells -- before, during and after a period in 2005 when global warming caused Caribbean Ocean sea-surface temperatures to rise. Symbiodinium trenchi is normally a rare species of...
Scientists take advantage of 'experiment of nature' to discover new insights into coral bleaching.
Nephtheidae is a family of soft corals known as carnation corals, tree corals or colt soft corals. These corals are very striking and show a wide range of rich colors including red, pink, yellow and purple. These corals are mainly tree-like in that they branch out and have little knobs on the end of their rubbery branches. Another name given these animals are broccoli corals, due to the fact that their polyps retract in the daytime, giving them the resemblance of the vegetable. The polyps...
Fungia scutaria is a species of mushroom coral in the family Fungiidae. It is found in the Indo-Pacific oceanic region. It occurs on upper reef slopes especially where there is considerable water movement. It is typically found on sand beds or coral fragments. It lives as a single individual rather than as a colony and is detached from the seabed. It has an elongated shape and can grow quite large. The polyp can be up to 6.7 inches long and is embedded in a cup-shaped hollow known as a...
Astrocoeniidae is a family of stony corals endemic to the waters around Papua New Guinea and northern Australia. Their habitats are steep slopes where strong currents rise from below, in crevices and below overhangs. These are reef-building colonial corals containing an algae known as zooxanthallae. These algae typically encrust corals up to 20 inches in diameter. On reef slopes, where water is more turbid (cloudy/murky), they are much smaller, only reaching 2 inches across. The World...
Alcyoniidae is a family of leathery corals that occur globally in temperate and tropical seas. These reef dwellers are often found in wave-exposed areas of reef crests, less turbid waters in lagoons, on steep slopes, under overhangs, and at depths of 100 feet and deeper. A colony of leathery coral is stiff, hard, and inflexible. It is composed of tiny polyps projecting from a shared leathery tissue. There are two kinds of polyps seen in Alcyoniidae corals: autozooids have long trunks and...
