Interesting article by Ken Thompson in the Telegraph touching the evolution of seaweeds. Brown seaweeds "kidnapped" a red alga and its chloroplasts, then used them to build a big photosynthetic organism.

Animals and plants are eukaryotes (organisms whose cells contain nuclei, unlike bacteria, which don’t). Eukaryotes themselves never evolved the ability to photosynthesise – they simply “borrowed” the ability by engulfing a photosynthetic bacterium, which eventually became a chloroplast. This crucial event happened only once in the entire history of life, somewhere around a billion years ago. The direct line of descent from this event branched a very long time ago. One branch became the green plants, while the other became the red seaweeds, so there’s a very good argument for calling red seaweeds plants; not only are they large and photosynthetic, they’re even related (distantly) to green plants.

In another part of the evolutionary forest altogether, unrelated to green plants, animals and fungi, in fact unrelated to anything you’ve ever heard of, another group of organisms acquired chloroplasts “second hand” by kidnapping a red alga, and then used them to build a big photosynthetic organism. These are the brown seaweeds

Scientists urge divers to remove lionfish in the Mediterranean Sea

Lionfish have begun invading the Med - they have already colonised the south coast of Cyprus.

Lionfish spawn every four days, year-round, producing around two million floating eggs a year. These travel with water currents for about a month before they settle. They can spread very quickly and prompt action by divers and fishermen is all that will prevent them from spreading further.

The fish have very few predators, although large grouper will sometimes eat them.

When out of their own Red Sea environment, lionfish become a serious threat to the diversity of their foreign home. Research in the Bahamas showed that lionfish caused reductions of up to 80% in the recruitment of native fishes on experimental reefs.

+Per-Erik Einerth They are beautiful in their own Red Sea environment.They cause lots of damage where they are not native though because they eat so many fish, have practically no predators in their new areas and are very successful at reproducing. They have reduced the population of of small native reef fishes by up to 95% at some invaded sites.

More fish in Indonesia shark sanctuary
Good news for Indonesia’s shark sanctuary: sharks and other fish are more abundant within zones with fishing restrictions according to a new study. Bad news for the people who fish for a living – they sometimes turned to crime to make ends meet.

Vanessa Jaiteh examined the impact of no-take zones on both sharks and people inside a recently established shark sanctuary along the coastal area of Raja Ampat, Indonesia. Working with local scientists from The Nature Conservancy, she measured the abundance of sharks and other fishes within two no-take zones (where fishing was prohibited) and one open access zone where fishing for sharks and other species continued unabated. The no-take zones were established by Misool Eco Resort in partnership with local communities with traditional land and sea rights to the area. Predictably, abundance levels for all fishes – mackerels, tunas, snappers, groupers and sharks – were much higher in the no-take zones when compared to the open access area.

The second phase of the study – an examination of perceptions and behavioral changes in people from coastal communities – revealed that most people living outside Raja Ampat, but travelling to fish in this regency, were unsure of why sharks were being protected. In interviews conducted with people simultaneously with field surveys on sharks and fish, respondents felt that government agencies were not considering their dependence on fishing for existence. Also, participants in the survey indicated that fishing closures not only forced them to shift their activities to unprotected areas, but also prompted some to engage in illicit activities such as the trafficking of illegal petrol.

“In some areas, ecotourism centered on sharks and coral reefs actually provides a livelihood alternative to fishing,” said Jaiteh. “However, we now realize that it also may be shifting fishing pressure to other areas and promoting illegal activity. Only a multi-dimensional effort focused on both protection of sharks and livelihood security will achieve sustainable results, with benefits to both overharvested marine life and coastal fishing communities.”

Lionfish begin invasion into Mediterranean Sea: Cyprus already colonised
According to evidence from scuba divers and fishermen, lionfish have recently increased in abundance and within just one year have penetrated almost the entire south eastern coast of Cyprus.

The authors of a new report into the Mediterranean lionfish, published in Marine Biodiversity Records, are urging divers and fishermen to remove the lionfish when they see them.

Lionfish feed on a variety of fish and crustaceans, with large individuals preying almost exclusively on fish. They can live for 15 years.

Lionfish spawn every four days, year-round, producing around two million floating eggs a year. These travel with water currents for about a month before they settle.

When out of their own Red Sea environment, lionfish become a serious threat to the diversity of their foreign home. Research in the Bahamas showed that lionfish caused reductions of up to 80% in the recruitment of native fishes on experimental reefs.

'Zombie corals' pose new threat to world's reefs writes Damian Carrington in today's Guardian newspaper.

Zombie corals, which look healthy but cannot reproduce, have been discovered by researchers, dashing hopes that such reefs could repopulate areas destroyed by bleaching.

Part of the problem is aerosol sunscreen,

The places with the heaviest tourism had the most severe damage to coral reproductive capability.

Oxybenzone, a common UV-filtering compound in sunscreen, kills coral but also causes DNA damage in adult coral and deforms the larval stage, making normal development unlikely.

The research also showed the toxic effects to coral, sea urchin embryos, shrimp larvae, and fish larvae exposed to preservatives, UV absorbers and microbeads from personal care products.
