Evolution in action: Genetic study may answer why we have plenty of fish in the sea
(PhysOrg.com) -- Three-spine sticklebacks aren't as pretty as many aquarium fish, and anglers don't fantasize about hooking one. But biologists treasure these small fish for what they are revealing about the ...

Diseases and sex: The cocktail maintaining immune gene variation
The great variation of a specific form of immune genes makes organ transplants so complicated. On the other hand, we need such a great variability in order to resist infectious diseases. This is why it also ...

Noise distracts fish from their dinner
Using underwater speakers to play noise at levels similar to those produced by recreational speedboats, the researchers found that three-spined sticklebacks exposed to even brief noise playback made more foraging mistakes ...

Ecologists get fish eye view of sexual signals
Carotenoid pigments are the source of many of the animal kingdom's most vivid colours; flamingos' pink feathers come from eating carotenoid-containing shrimps and algae, and carotenoid colours can be seen among garden birds ...

Tiny fish evolved to tolerate colder temperature in three years: study
University of British Columbia researchers have observed one of the fastest evolutionary responses ever recorded in wild populations. In as little as three years, stickleback fish developed tolerance for water ...

Introducing Robofish: Leading the crowd in studying group dynamics
UK scientists have created the first convincing robotic fish that shoals will accept as one of their own. The innovation opens up new possibilities for studying fish behaviour and group dynamics, which provides ...

Potential antifouling substance can cause paler fish
The sedative medetomidine has proved effective at inhibiting fouling and is now being trialled by the EU as an ingredient for the antifouling paints of the future. Research at the University of Gothenburg, ...

Researchers find first-ever 'wanderlust gene' in tiny bony fish
(PhysOrg.com) -- 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 ...

Researchers document rapid, dramatic 'reverse evolution' in the threespine stickleback fish
Evolution is supposed to inch forward over eons, but sometimes, at least in the case of a little fish called the threespine stickleback, the process can go in relative warp-speed reverse, according to a study led by researchers ...
