Coral bleaching threatens the diversity of reef fish

Thu, 05 Apr 18 00:00:40 -0700

New research reveals that global warming also affects fish who depend on corals. The Great Barrier Reef is revered for its kaleidoscope of color. New international research led by Ph.D. student Laura Richardson of the ARC Centre of Excellence for Coral Reef Studies at James Cook University reveals that coral bleaching events not only whitewash corals, but can also reduce the variety of fish occupying these highly valued ecosystems.

The great acceleration reaches new heights

Wed, 04 Apr 18 00:07:30 -0700

An international team of researchers, including researchers at Edysan laboratorie (CNRS / Université de Picardie Jules Verne) has observed an acceleration in the increase of biodiversity on mountain peaks in Europe. This is a new indicator of the 'great acceleration': an increasingly rapid inflation of different parameters around the world (glacier retreat, coral bleaching, etc.) seen in recent years as a result of climate change. Mountain ecosystems could be seriously disturbed as a result.

GPM satellite probes Tropical Cyclone Iris weakening near Australian coast

Wed, 04 Apr 18 00:09:30 -0700

Coral reefs protect coasts from severe storms

Mon, 02 Apr 18 00:16:00 -0700

Coral reefs can naturally protect coasts from tropical cyclones by reducing the impact of large waves before they reach the shore, according to scientists. Tropical cyclones wreak havoc on coastal infrastructure, marine habitats and coastal populations across the world. However, Dr. Michael Cuttler, from the ARC Centre of Excellence for Coral Reef Studies at the University of Western Australia, says that for coastlines facing a direct cyclone impact, a fringing reef can protect the beach from extensive erosion.

Herring larvae could benefit from an acidifying ocean

Thu, 29 Mar 18 00:12:30 -0700

Excess CO2 in the atmosphere is making the oceans more acidic. Some studies show that's bad news for fish, including commercially important species. But a new study shows that herring might be able to tolerate this change.

Untangling the role of climate on sediment and reef evolution over millennial timescales

Tue, 27 Mar 18 00:02:40 -0700

Climatic variability like precipitation changes or increase in extreme events such as storms and tropical cyclones is known to significantly modify the Earth's surface. Yet, our understanding of how sediment dynamics and reef evolution might respond to these changes is still limited. In a recent study, a team of researchers has designed a new model that simulates sediment transport from mountains to coasts, reworking of marine sediments by wave-induced currents, and development of coral reefs.

New research shows how submarine groundwater affects coral reef growth

Tue, 27 Mar 18 00:12:40 -0700

Although submarine groundwater is natural, it can act as a conduit for highly polluted water to shorelines.

Coral reef experiment shows: Acidification from carbon dioxide slows growth

Wed, 14 Mar 18 00:09:00 -0700

Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhouse gas emissions are not abated.

NASA finds strongest storms in newly formed Tropical Cyclone 13P

Mon, 12 Mar 18 00:07:40 -0700

Infrared satellite data showed Tropical Cyclone 13P quickly developed powerful storms with very cold cloud top temperatures. NASA's Aqua satellite analyzed the system in infrared light to determine where its strongest storms were located.

How the color-changing hogfish 'sees' with its skin

Mon, 12 Mar 18 00:10:10 -0700

The hogfish can go from white to reddish in milliseconds as it adjusts to shifting conditions in the ocean. Scientists have long suspected that animals with quick-changing colors don't just rely on their eyes to tune their appearance to their surroundings -- they also sense light with their skin. But exactly how remains a mystery. A study reveals that hogfish skin senses light differently from eyes.

No fish story! Research finds marine reserves sustain broader fishing efforts

Tue, 06 Mar 18 00:16:10 -0800

First evidence of surprising ocean warming around Galápagos corals

Wed, 21 Feb 18 00:02:00 -0800

A new analysis of the natural temperature archives stored in coral reefs shows the ocean around the Galápagos Islands has been warming since the 1970s. The finding surprised the research team, because the sparse instrumental records for sea surface temperature for that part of the eastern tropical Pacific Ocean did not show warming. Scientists thought strong upwelling of colder deep waters spared the region from the warming seen in other parts of the Pacific.

Sea urchins erode rock reefs, excavate pits for themselves

Wed, 21 Feb 18 00:06:30 -0800

Through their grazing activity, sea urchins excavate rock and form the pits they occupy. This activity may cause significant bioerosion of temperate reefs, according to a study published Feb. 21, 2018 in the open-access journal PLOS ONE by Michael Russell from Villanova University, US, and colleagues.

Study exposes misperception of poaching on the GBR and its remedy

Tue, 20 Feb 18 00:00:00 -0800

First video of 'Dumbo' octopod hatchling shows that they look like mini-adults

Mon, 19 Feb 18 00:09:10 -0800

Researchers who've gotten the first look at a deep-sea 'dumbo' octopod hatchling report in Current Biology on Feb. 19 that the young octopods look and act much like adults from the moment they emerge from an egg capsule. Dumbo octopods are so named because their fins resemble Dumbo the elephant's ears.

Hurricanes Irma and Maria temporarily altered choruses of land and sea animals

Thu, 15 Feb 18 00:01:20 -0800

Audio recordings of Hurricanes Irma and Maria's passage over Puerto Rico document how the calls of coastal critters changed in response to the deadly storms. The hurricanes caused a major disruption in the acoustic activity of snapping shrimp, a reduction in insect and bird sounds, and potentially an intensification of fish choruses, according to new research presented at the Ocean Sciences Meeting Friday.

How the cuttlefish spikes out its skin: Neurological study reveals surprising control

Thu, 15 Feb 18 00:05:00 -0800

Wouldn't it be useful to suddenly erect 3-D spikes out of your skin, hold them for an hour, then even faster retract them and swim away? Octopus and cuttlefish can do this as a camouflage tactic. A new study clarifies the neural and muscular mechanisms that underlie this extraordinary defense tactic, conducted by scientists from the Marine Biological Laboratory (MBL), Woods Hole, and the University of Cambridge, UK, and published in iScience.

Snapping shrimp may act as 'dinner bell' for gray whales off Oregon coast

Tue, 13 Feb 18 00:02:50 -0800
