Brett Smith for redOrbit.com – Your Universe Online A new study on the schooling habits of fish could provide new insights into the social behaviors and natural variations of humans. Published on Thursday in the journal Current Biology, the new study was able to trace the tendency and the aptitude for schooling to different genomic regions in the threespine stickleback, a small fish that lives in the Northern Hemisphere. "The motivation to be social is common among fish and...

New work from the HudsonAlpha Institute for Biotechnology, with collaborators at Stanford University and five other groups, has pinpointed evolution in action. By determining genomic sequence from many groups of stickleback fish, the scientists were able to show specific genomic changes leading to the ability of different fish populations to adapt to new environments. "We were pleased with the ability of genomics to show us what molecular changes are important in evolutionary processes,"...

University of British Columbia researchers have observed one of the fastest evolutionary responses ever recorded in wild populations. In as little as three years, stickleback fish developed tolerance for water temperature 2.5 degrees Celsius lower than their ancestors. The study, published in the current issue of the Proceedings of the Royal Society B, provides the some of the first experimental evidence that evolution may help populations survive effects of climate change. Measuring three to...

University of Oregon labs combine emerging technologies to identify gene regions underlying adaptation Twenty billion pieces of DNA in 100 small fish have opened the eyes of biologists studying evolution. After combining new technologies, researchers now know many of the genomic regions that allowed an ocean-dwelling fish to adapt to fresh water in several independently evolved populations. The discovery -- made possible in a project funded by the National Science Foundation and National...

 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. That surprised researchers, who expected the same genes would control the same changes in both related fish."We knew that in many cases of evolution, the same gene has been used over and over again "“ even in different species "“ to give the same anatomy," says Mike Shapiro, first author of the new study and...

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. The researchers said that...

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...

By ELIE DOLGIN In a dark, damp corner of a University of Wisconsin-Madison laboratory, Jenny Boughman dropped a 3-inch, three-spined female fish into a fish tank, and waited. 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...
