GLOBALLY, INVASIVE RATS ARE ONE OF the major problems affecting seabirds breeding on islands. When rats jump ship and colonise, their predation of eggs and chicks can lead to massive slumps in seabird numbers. In turn, this makes the rain of seabird poo washing out to surrounding waters shrink from a torrent to a trickle. Surprisingly, for jewel damselfish living on coral reefs there, that affects their habits - including how they react to other fish.
Jewel damselfish are aggressively territorial and will attack intruders - even much larger fish - that stray into territories they hold over small patches of reef.

Does cloning create identical copies?
EMBRYOS ARE MADE OF STEM CELLS that divide to give rise to different types of cells, everything from skin to brain cells. Scientists once thought that reproductive cloning creating a genetically identical copy of an individual organism - would be impossible without using stem cells and that the path leading to mature 'differentiated' cells was irreversible. But clawed frogs proved them wrong...
