A new study demonstrates a female preference for rare males using an experiment in a wild population, rather than a laboratory setting. When it comes to choosing a mate, female guppies don't care ...

Thanks to a unique combination of biology and ecology, the guppies have provided researchers with insights into evolution for decades. Evans and Fitzpatrick have pushed those insights a step further, ...

Any owner of a freshwater aquarium likely has had guppies (Poecilia reticulata), those small brightly colored fish with a propensity for breeding. Now guppy populations manipulated in natural habitats ...

This is a preview. Log in through your library . Abstract When fish inspect a predator they incur risk. One way of reducing the cost of inspection is to approach predators in groups large enough to ...

Researchers used high-speed cameras to film male guppies as they jumped. When a guppy jumped out of a laboratory tank and nearly landed in her cup of tea, Daphne Soares couldn’t resist putting her ...

A new study of wild guppies could unsettle a decades-old idea about the role of danger in the evolution of aging. Biologists in the 1950s predicted that in a treacherous habitat, creatures would ...

TALLAHASSEE, Fla. — When it comes to choosing a mate, female guppies don't care about who is fairest. All that matters is who is rarest. Florida State University Professor Kimberly A. Hughes in the ...

When a guppy jumped out of a laboratory tank and nearly landed in her cup of tea, Daphne Soares couldn’t resist putting her current research on hold to investigate this strange leaping behavior. "The ...
