According to a British study published on Thursday, stickleback fish are more willing to take risks when in pairs. Although the stickleback fish tends to find protection in numbers, researchers also discovered the leading fish would become proportionally bolder depending on the shyness of the following fish. "Our study shows that the process by which leaders and followers emerge is a dynamic one," said Andrea Manica of the University of Cambridge. "Individuals aren't simply born leaders or...

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. On biological levels from molecular and genetic to developmental and morphological, and finally ending with the population level, it has proven far more complex than even imagined. Studies of stickleback have...

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. Measuring three to 10 centimeters long, stickleback fish originated in the ocean but began populating freshwater lakes and streams following the last ice age. Over the past 20,000 years "“ a relatively short time span in evolutionary terms "“ freshwater sticklebacks have lost their bony...

She sat perfectly still as she watched a male fish swim out slowly from its nest, beneath a cracked flower pot. At first, the male didn't notice the female among the strips of floating green, plastic table cloth that Boughman had ripped up to mimic a seaweed-like plant. Then he spotted her. He zigged left and...

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...
