Latest Stickleback Stories
Sticklebacks, the roaches of the fish world, are the ideal animal in which to study the genes that control body shape. They’ve moved from the ocean into tens of thousands of freshwater streams and lakes around the world, each time changing their skeleton to adapt to the new environment.
Many animals are able to discriminate between related and unrelated individuals but how they do so has proven remarkably difficult to understand. Joachim Frommen and colleagues at the University of Veterinary Medicine, Vienna have investigated the issue using the three-spined stickleback and its shoaling preferences as a model system.
Three-spine sticklebacks aren't as pretty as many aquarium fish, and anglers don't fantasize about hooking one.
Carotenoid pigments are the source of many of the animal kingdom's most vivid colors; flamingos' pink feathers come from eating carotenoid-containing shrimps and algae, and carotenoid colors can be seen among garden birds in blackbirds' orange beaks and blue tits' yellow breast feathers.
University of British Columbia researchers have observed one of the fastest evolutionary responses ever recorded in wild populations.
University of Oregon labs combine emerging technologies to identify gene regions underlying adaptation.
A gene previously associated with physical traits is also dictating behavior in a tiny fish widely regarded as a living model of Darwin's natural selection theory, according to a University of British Columbia study.
Scientists have discovered that sticklebacks exhibit an advanced, sophisticated learning technique never before seen in the animal world.
New research shows that when two species of stickleback fish evolved and lost their pelvises and body armor, the changes were caused by different genes in each species.
The Nine-spined Stickleback (Pungitius pungitius), is a species of fish in the Gasterosteidae family. It is found in Belarus, Belgium, Canada, China, Denmark, Estonia, Finland, France, Germany, Greenland, Ireland, Japan, South Korea, Latvia, Lithuania, Moldova, Republic of, the Netherlands, Norway, Poland, Russia, Sweden, Switzerland, Turkey, the United Kingdom, and the United States.
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...
