Drone Creates Detailed Coral Reef Maps
2013-10-16 15:47:05

[ Watch the Video: Coral Reef Mapping With The Help Of Drones ] Brett Smith for redOrbit.com - Your Universe Online The War on Terror may have given unmanned drones a bad name, but a research team from Stanford University just might be able to rehabilitate that image. Ved Chirayath, an aeronautics researcher, and Steven Palumbi, a marine biologist, have started using an unmanned drone and cutting-edge computer software to map and measure centuries-old corals. Equipped with several...

Eilat's Corals Have Better Chance Of Survival Than Other Sites
2013-09-30 10:40:55

The Hebrew University of Jerusalem Israel's southern Red Sea resort of Eilat, one of whose prime attractions is its colorful and multi-shaped underwater coral reefs, may have a clear advantage in the future over rival coral-viewing sites around the world, scientists at the Hebrew University of Jerusalem and Bar-Ilan University have found. Coral reefs, earth's richest and most diverse ecosystem, are deteriorating rapidly. One of the most devastating causes for that deterioration is coral...

Fish Species Losing Homes As Sea Anemones Suffer From Bleaching
2013-08-20 10:13:39

Brett Smith for redOrbit.com - Your Universe Online Marine biologists have been warning recently about the dangers of coral bleaching and new research from a team of international scientists indicates sea anemones are also susceptible to the color-sapping phenomenon that is thought to result from death of sea creatures’ symbiotic algae. In addition to being suspected of causing an increase in sea anemone mortality, bleaching also affects clownfish and 27 other fish species that depend...

Coral Reef Protection From Cloud Seeding
2013-07-11 04:51:24

April Flowers for redOrbit.com - Your Universe Online New research from the University of Leeds reveals threatened coral reefs could be protected from bleaching by warming oceans. The study proposes a targeted version of the geoengineering technique known as Marine Cloud Brightening (MCB) - seeding the clouds to cool sea surface temperatures - could give coral a fifty year "breathing space" to recover from acidification and warming. "Coral bleaching over the last few decades has been...

Coral Bleaching Study Explains Different Responses To Climate Change
2013-04-24 12:24:35

Brett Smith for redOrbit.com - Your Universe Online When corals become stressed, they expel their symbiotic algae companions in a process known as “bleaching.” Corals can survive the bleaching, but it leaves them highly vulnerable and often results in die-off. As a changing climate threatens to bleach the corals of the world´s oceans on a massive scale, a team of researchers from Northwestern University has found that some corals facilitate bleaching through the...

Using a world-first scientific discovery, Australian researchers are developing a stress-test for coral, to measure how coral reefs are being impacted by pressures from climate change and human activity. The scientists have found hemoglobin genes in the microalgae which live symbiotically with coral, which may provide a readout on how stressed a particular coral is — and how likely it is to bleach and die. Coral bleaching occurs when the symbiotic algae abandon the coral due to...

Increase In Coral Reef Bleaching Attributed To Climate Change
2013-02-25 19:26:09

Michael Harper for redOrbit.com — Your Universe Online Rising temperatures associated with climate change have already been shown to have an effect on a wide range of ecosystems and the creatures that reside within. Recent studies have now added coral reefs to the list of ecosystems that may be damaged as a result of climate change. Judging from new maps and models, the rising sea temperatures, which accompany climate change, could result in more frequent coral bleaching events,...

Investigating How Corals Survive In The Hottest Reefs On The Planet
2013-02-01 14:48:45

National Oceanography Centre, Southampton (UK) Coral reefs are predicted to decline under the pressure of global warming. However, a number of coral species can survive at seawater temperatures even higher than predicted for the tropics during the next century. How they survive, while most species cannot, is being investigated by researchers at the National Oceanography Centre, Southampton (NOCS) and New York University Abu Dhabi (NYUAD). We tend to associate coral reefs with tropical...

Coral Can Have Too Much Of A Good Thing
2012-10-15 04:54:29

redOrbit Staff & Wire Reports - Your Universe Online While the single-celled algae that live inside corals typically play a vital role in keeping the reefs healthy, a new study suggests that an overabundance of the symbiotic organisms could have a negative effect on them. According to scientists at the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science, these algal symbionts provide corals with the energy needed to build larger reef frameworks. When...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
