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.Researchers from the UBC Biodiversity Research Centre created mini-ecosystems in large aquatic tanks using different species of three-spine stickleback fish and saw substantial differences in the ecosystems in as little as 11 weeks.Their findings are published in today's...

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.By randomly pairing fish of varying degrees of "boldness," the researchers showed that each member of a pair adopts the role of leader or follower. More importantly, they found, the behavior of each member of the pair is strongly influenced by its partner." Our study shows that the process by...

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...

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...
