Where Humans Live, The Corals Fail Posted By : miumiu
2008-02-04 14:02:00 The worlds coral reefs are in alarming decline, and a recent groundbreaking study singles out human settlement, especially coastal development and agriculture, as the main culprit, even more so than warming sea waters and acidification linked to global warming.

Fossilized deep-ocean corals might reveal ancient climate secrets
2008-02-02 11:58:00 Scientists aboard the Southern Surveyor, a research vessel, have retrieved live and fossilized deep-ocean corals from a depth of 1,650 meters near the Tasman Fracture Zone, south-east of Tasmania, which might reveal ancient climate secrets.The samples were collected by scientists from the US and CSIRO’s (Commonwealth Scientific and Research Organization) Wealth from Oceans National Research Flagship.The composition of deep-sea corals is used to determine past ocean conditions, such as temperature, salinity and the mixing of surface and deep-water layers, over tens to hundreds of thousands of years.“These corals are evidence of an extinct coral reef,” said the voyage’s Chief Scientist, CSIRO Marine and Atmospheric Research’s Dr Ron Thresher.“Our sampling came up with some very old fossil corals of the type we are now seeing live and forming extensive reefs at depths of 800-1300 metres. This suggests that the reef extended much deeper in the past,&r...

Starfish outbreak threatens corals
2008-01-24 11:42:00 Outbreaks of the notorious crown of thorns starfish now threaten the "coral triangle," the richest center of coral reef biodiversity on Earth, according to recent surveys by the Bronx Zoo-based Wildlife Conservation Society and ARC Centre of Excellence for Coral Reef Studies.The starfish - a predator that feeds on corals by spreading its stomach over them and using digestive enzymes to liquefy tissue - were discovered in large numbers by the researchers in reefs in Halmahera, Indonesia, at the heart of the Coral Triangle, which lies between Indonesia, Malaysia, the Philippines, Papua New Guinea and the Solomon Islands. It is considered the genetic fountainhead for coral diversity found on Australia's Great Barrier Reef, Ningaloo and other reefs in the region.Scientists fear the outbreak is caused by poor water quality and could be an early warning of widespread reef decline.Recent surveys of Halmahera by the Wildlife Conservation Society and ARC Centre of Excellence for Coral Reef ...
Corals of the Egyptian Red Sea-Photos
2008-01-24 02:03:00 Corals belong to a group of animals called Cnidarians. This includes hard and soft corals, sea fans, gorgonians, jelly fish and sea anemones. Amongst other common characteristics is the presence of stinging cells (nematocysts) which are used to catch prey.A single coral animal is a polyp - the attractive "flowery" item looking like an anemone. The soft coral shown above is actually a colony of animals, each connected to its neighbour by living tissues. Soft corals are not reef-building, although they do secrete limestone. In their case this is as internal crystals called sclerites or spicules. Because soft corals do not have large skeletons, they grow faster than hard coralsEight feathery tentacles surround the coral's mouth and whip food into it. They filter-feed: removing plankton from water flowing around the colony. Relatively recent data on soft corals indicates that they feed on very small planktonic particles, such as single-celled algae, rather than larger larvae as had pre...
What are Corals and Coral Reefs?
2007-10-30 17:44:00 Appearing as solitary forms in the fossil record more than 400 million years ago, corals are extremely ancient animals that evolved into modern reef-building forms over the last 25 million years. Coral reefs are unique (e.g., the largest structures on earth of biological origin) and complex systems. Rivaling old growth forests in longevity of their ecological communities, well-developed reefs reflect thousands of years of history (Turgeon and Asch, in press).Corals and their KindCorals are anthozoans, the largest class of organisms within the phylum Cnidaria. Comprising over 6,000 known species, anthozoans also include sea fans, sea pansies and anemones. Stony corals (scleractinians) make up the largest order of anthozoans, and are the group primarily responsible for laying the foundations of, and building up, reef structures. For the most part, scleractinians are colonial organisms composed of hundreds to hundreds of thousands of individuals, called polyps.
Moonlight spurs corals to spawn
2007-10-22 07:57:00 By the light of the silvery moon, corals get in tune, and soon, it's a spawning delight. While that silvery moon was written about people, the songwriter understood the motivation. Now, scientists think they may have found out how reef-building corals manage to coordinate their sex lives in moonlight bay. In late spring it's reef madness as corals release sperm and eggs into the water for a few nights after a full moon. But how do they know? Researchers led by Oren Levy of the Center for Marine Studies at the University of Queensland, Australia, studied corals on Australia's Great Barrier Reef.They report in Friday's issue of the journal Science that while corals don't have eyes they are able to sense changes in light — especially blue light — and respond to them. The corals contain ancient proteins called cryptochromes which react to light. Cryptochromes have also been found in mammals and insects where they effect the circadian clock that regulates the daily rhythms of li...
Corals May Have Defense Against Global Warming
2007-10-05 12:25:00 Ancient corals may have been more adaptable to changing ocean chemistry than previously thought, a new study shows. The findings may offer hope that modern corals can adapt as global warming causes seas to become more acidic. These fossil corals in diverse reef communities adjusted to an acidic environment by altering the way they built their chalky skeletons. Modern hard corals—known as scleractinians—form reefs of thousands of tiny skeletons made from a calcium carbonate called aragonite.Aragonite is susceptible to the corrosive effects of acidic oceans, which today has become a byproduct of a build-up of carbon dioxide in the atmosphere. "We now have many different arguments to prove that these corals were actually made originally out of calcite—and not just aragonite that was transformed after the coral died and become fossilized," said study co-author Jaroslaw Stolarski, a paleontologist from the Institute of Paleobiology at the Polish Academy of Sciences. Curious Coral T...
Good Starter Corals For The Beginner
2007-09-05 22:33:00 When starting a new reef tank, especially if you are a beginner to the hobby as I am sure you may by now appreciate there is at times quite a lot to learn. Starting a reef aquarium is only as hard as you allow it to be. Why learn all about advanced water chemistry for example at the very beginning - learn the basics first, get your aquarium running and then carry on reading, studying and learning. Why make starting an aquarium harder by including corals in your aquarium where you have to learn a lot about how to care for and maintain them. There are some corals which are exceptionally hard to care for so why not keep some of the easier to keep corals whilst you are learning the basics and as you learn more and your aquarium ages then you can add more.

Aquarium Additives and Hard Corals
2007-08-03 07:22:00 The reef aquarium with hard corals (SPS) is the desire of many an aquarist. The sight of pictures on the internet and in books only serves to increase that desire. With modern aquaria and equipment, plus the knowledge gained over recent years, this desire can be met, and more easily than some suspect. It is taken as read that the need for high water quality is understood. High water quality means a proper and stable pH, between 8.0 and 8.4, nitrate less than 10 ppm (parts per million), phosphate preferably undetectable, but no more than 0.03 ppm, and ammonia and nitrite undetectable. Equipment should include a properly sized and efficient protein skimmer. Water movement, which I consider a part of water quality, should be vigorous and chaotic. There is also a need for strong lighting, the best of which is metal halide, supplemented by actinic T5 fluorescents. A greater number of T5 fluorescents can be used without a metal halide, as many as can be fitted into the aquarium including...

Aquarium Additives and Soft Corals
2007-08-02 00:52:00 Keeping a seawater aquarium nowadays is a generally straightforward affair. Provided the design and setting up is satisfactory and the aquarist does the necessary periodic maintenance properly, the aquarium will give pleasure for a long period. Commercial seawater mixes are good overall. The mix will provide adequate levels of elements in the seawater, but checks should still be made, particularly when the aquarium is matured and settling and onwards, to ensure that important parameters are as they should be.

How To Acclimitise New Corals And Fish Correctly
2007-07-26 21:50:00 It always amazes me how many people I see or talk to who purchase a marine animal, take it home, open the bag and pour it into their aquarium. I can never understand why some people do not acclimitise their purchases properly, it could be laziness, lack of knowledge, impatience etc but one thing is for certain life is on the line here so it must be done correctly. The purpose of acclimatisation is simple - the water that the animal is packaged in may have a different temperature, pH and salinity than that of your aquarium. Aquatic life (especially corals and invertebrates) are very sensitive to minor changes in water parameters therefore acclimatisation is a definate requirement for success.

Caribbean Corals In Danger Of Extinction: Climate Change, Warmer Waters Cit
2007-06-13 07:56:00 Caribbean coral species are dying off, indicating dramatic shifts in the ecological balance under the sea, a new scientific study of Caribbean marine life shows.The study found that 10 percent of the Caribbean's 62 reef-building corals were under threat, including staghorn and elkhorn corals. These used to be the most prominent species but are now candidates to be listed as Critically Endangered on the IUCN Red List of Threatened Species."One of the Atlantic Ocean's most beautiful marine habitats no longer exists in many places because of dramatic increases in coral diseases, mostly caused by climate change and warmer waters," said Dr. Michael L. Smith, director of the Caribbean Biodiversity Initiative at Conservation International.A gathering of 23 scientists in Dominica in March 2007 analyzed data on Western Tropical Atlantic corals, seagrasses, mangroves and algae, which are fundamental components of marine ecosystems providing food and shelter for numerous other organisms and ...

Corals in UMS?
2007-03-05 00:58:00 Went to UMS (University Malaysa of Sabah or something lidat) in Kota Kinabalu, Sabah last December. The university was surprisingly beautiful with nice landscaping and stuff. The best part about it was that it was just beside the sea. So students over there can study while overlooking the sea.So lucky.Anyway, they had a akuarium over there. A teeny tiny one. You have to pay RM 2 for the entrance fee if I'm not mistaken.Is this coral nice?Or this wan is nicer?Was testing the light and found out actually both looks nice. Couldn't decide on which is nicer.
