Latest Stickleback Stories
Canadian scientists say they have conducted the first experiment that shows the evolution of new species impacts the environment. Scientists at the University of British Columbia created mini-ecosystems in large aquatic tanks using different species of three-spine stickleback fish and saw substantial differences in the ecosystems within 11 weeks. Stickleback fish originated in the ocean, but began populating freshwater lakes and streams following the last ice age.
Scientists have come to agree that different environments impact the evolution of new species. Now experiments conducted at the University of British Columbia are showing for the first time that the reverse is also true.
Followers are just as important to good leadership as are the leaders themselves, reveals a new study of stickleback fish published online on January 29th in Current Biology, a Cell Press publication.
According to a British study published on Thursday, stickleback fish are more willing to take risks when in pairs.
The stickleback fish, Gasterosteus aculeatus, is one of the most thoroughly studied organisms in the wild, and has been a particularly useful model for understanding variation in physiology, behavior, life history and morphology caused by different ecological situations in the wild.
Shedding some genetically induced excess baggage may have helped a tiny fish thrive in freshwater and outsize its marine ancestors, according to a UBC study published Thursday in Science Express.
The Nine-spined Stickleback (Pungitius pungitius), is a species of fish in the Gasterosteidae family.

The Three-Spined Stickleback, Gasterosteus aculeatus, is a fish native to much of northern Europe, northern Asia and North America. It has been introduced into parts of southern and central Europe. Three subspecies that are currently recognized by the IUCN are Gasterosteus aculeatus aculeatus, which is found in most of the species range, and is the subspecies most strictly termed the Three-Spined Stickleback; its common name in England is the Tiddler, although "tittlebat" is also sometimes...
