UBC researchers find first-ever 'wanderlust gene' in tiny bony fish
Date:8/4/2009

A gene previously associated with physical traits is also dictating behaviour in a tiny fish widely regarded as a living model of Darwin's natural selection theory, according to a University of British Columbia study.

Measuring three to 10 centimetres, stickleback fish originated in the ocean but began populating freshwater lakes and streams following the last ice age. Over the past 15,000 years, freshwater sticklebacks have lost their bony lateral plates, or "armour," in these new environments. Scientists have identified a mutant form of a gene, or allele, that prohibits growth of armour and is commonly found in freshwater sticklebacks but exists in less than one per cent of their marine counterparts.

Now UBC PhD candidate Rowan Barrett and colleagues from UBC's Dept. of Zoology have found that the gene may also be contributing to the fish's tendency to relocate instead of adjusting to their surroundings the first time a gene associated with this type of behaviour has been identified. Their findings are published today in the journal Biology Letters.

"Contrary to our assumption, the low-armour allele is not linked to a preference for fresh water, or low salinity," says Barrett. "Instead, we found a strong association between having the allele and the fish's inclination to move into different salinities a sort of 'wanderlust gene,' if you will instead of staying put and acclimatizing to the current salinity."

"The combination of physical and behavioural traits could explain why the low-armour allele keeps turning up during marine sticklebacks' 'invasion' of freshwater habitats," says Barrett.

"The new behavioural association we've identified may also shed light on why there's still a small but constant population of armour-less sticklebacks in the sea despite the high predation there. Sticklebacks with the mutant allele just like to go to new places."
