from the article:
"Rohwer and his colleagues tested their idea by putting pieces of Panamanian corals in cups with seawater, and adding different “treatments†to each cup, and essentially “just look[ing] for the coral to die,†Rohwer said.
Organic carbon was indeed the biggest coral killer. "
does this seem like they know what their doing? i think most corals in a cup will die, without anything being added.

that article also says that the corals are dieing from diseases that we pass on to them. so then how can our captive corals not get sick and die too?
i dont beleive in global warming, i think its more like a weather change.
though i must admit that runoff from rivers is also a major player, fish caught in the Mississippi are not good to eat all the way up in Minnesota, i hate to imagine what the fish have in them at the end of the river...
back on topic, there is always a bacterial risk when you enter water that is not safe to drink. you can get the same infections from the lake as you can from your fish tanks.

Stupid question of the night, but as I don't want urchins, never really looked into it- do urchins have toxins or is it simply the flesh wound you need to look out for that one?
Ben
Depends on the species of urchin. Some have no toxins, some have mild toxins like the long spined urchin, than there are few that can land you in the hospital. Fortunately the ones most commonly found in the hobby range between no toxin and mild. The only one I've seen in the trade on occasion that can land you in the hospital is usually sold as "fire urchin" or "electric urchin".

Good to know. Saw one of the electric urchins in a shop a while back. I think its time to dig a bit more into these urchins.
Thanks for the reply,

It's really scary that this is really how people are forming their opinions on scientific subjects.
The article was written by a non-scientist for an audience of non-scientists. It's nothing more than a cartoon of the actual work being done and isn't meant for critical reading or a real understanding of the issue. You can't possibly cover at least 6 different papers in a half page article (which this article tries to do) and dumb it down enough for with no previous knowledge of the subject without oversimplifying things. It's especially hard when you have no knowledge of the subject yourself and haven't read the papers. That's why before you form your opinions you should read what the experts themselves are saying, not what some journalist thinks they said.

Nowhere in the article or the original papers do the authors claim that people are giving the corals diseases. They only say that the life already present on the corals, which is normally harmless, becomes dangerous when organic carbon levels rise. You're also making the erroneous assumption that our corals don't get sick and die.
Yes, they knew what they were doing. No, they didn't literally put corals into cups and wait for them to die. They put corals in individual tanks and exposed them to various components of runoff and sewage to see which had the biggest negative impact on coral health. There were also controls to make sure that just being in the "cups" didn't kill the corals and the experiments were repeated in the wild as well. Even in the case with the highest mortality, (increased carbon) only about 35% of the corals died.

I just got back from a seminar Dr. Rohwer gave about his work, so my understanding is a little bit better now that I've had a chance to ask him some questions and see some pictures of the experimental setups.
The "coral killing machine" as he called it was a big raceway tank filled with large teflon beakers. Each beaker had its own pump outlet providing it with flow and fresh water, which then overflowed the top of the beaker into the raceway. There was also a port in each outlet pipe just before it entered the beaker where they could add whatever chemical they were testing with.

They were only using short sequences of the DNA to identify the microbial and viral communities, so they only identified them to family in most cases.

Supposedly...*My old boss, years ago, was moving liverock around when he pricked his finder pretty good on a small tubeworm. Six months later, or so, the felt like he was getting tendonitis or something, come to find out, the worm of somesort had lodged in his finder and was living of of his tendon*
