Research sometimes means looking for one thing and finding another. Such was the case when biology professor Alice Gibb and her research team at Northern Arizona University witnessed a small amphibious fish, the mangrove rivulus, jump with apparent skill and purpose out of a small net and back into the water. This was no random flop, like you might see from a trout that´s just been landed. The rivulus seemed to know what it was doing. They hadn´t expected to see that behavior,...

Spanish and French researchers have evaluated the spread of the invasive mosquitofish Gambusia holbrooki, which is native to the United States and lives in Mediterranean rivers in Spain and France. The scientists warn that climate change will extend the current distribution area of this and other invasive species to the north. The scientists at the University of Girona (UG) who coordinated this study say it is important to understand the interaction between climate change and invasive...

How social status is negotiated among fishes Being the neighborhood bully has its obvious advantages, but it becomes useless if your authority is continuously being challenged. In many animal species, however, stable hierarchies are routinely formed in which some individuals seem to slip naturally into their dominant role whereas others resign themselves to play the part of lowly subordinates. But why do the latter embrace this fate so readily instead of putting up a fight? A research team...

By Lisa M Krieger The scrappy little mosquitofish, the pit bull of ichthyology and the region's leading defense against West Nile virus, is a savior to insect-infested waters. Unless you're a frog. Yes, the fish dines on larval mosquitoes, as intended. But scientists have learned it also has an appetite for the tadpoles of frogs, toads and other amphibians -- including the threatened red- legged frog and the endangered Santa Cruz long-toed salamander. "Frog populations have disappeared...
