Much of the Earth's species diversity is concentrated into a few relatively small areas. Twenty-five regions have been identified which together cover only 1.4% of the Earth's land surface but contain nearly half of all plant species and a third of all terrestrial vertebrate species. All are under pressure from human activities.

The two types of seaweed, which grow more than 200m underwater, represent previously unrecognised ancient forms of algae, say the scientists. As such, the algae could belong to the earliest of all known green plants, diverging up to one billion years ago from the ancestor of all such plants.

A survey of about 600 scientists published this week found that a majority think it's time to consider conservation triage - focusing resources on animals that can realistically be saved, and giving up on the rest. Those that fall into the too-expensive-to-save category, it has been suggested, might include the panda and the tiger. So, should we give up on one endangered species to save another?

The authors said that 70% of the world's languages were found within the planet's biodiversity hotspots. Data showed that as these important environmental areas were degraded over time, cultures and languages in the area were also being lost.
