SFU Newly published research co-authored by scientists at Simon Fraser University and the Raincoast Conservation Foundation shows juvenile coho salmon benefit from dining on the distant remains of their spawning pink and chum cousins. While juvenile coho salmon feed directly on spawning pink and chum salmon carcasses and eggs, even coho with no direct contact with spawning pink and chum benefit from their nutrient contributions to stream ecosystems. The new research shows that...

Dam Removal Improves Shad Spawning Grounds
2014-05-22 16:30:47

North Carolina State University Research from North Carolina State University finds that dam removal improves spawning grounds for American shad and seems likely to improve survival rates for adult fish, juveniles and eggs – but for different reasons. The researchers focused on a small tributary in North Carolina called the Little River, where three dams were removed in the late 1990s and early 2000s. American shad (Alosa sapidissima) spend the bulk of their adult lives in saltwater,...

Brett Smith for redOrbit.com - Your Universe Online Many anglers preach catch-and-release fishing methods as not only humane, but a good practice for maintaining stocks of fish living in a lake. However, a new report from researchers at the University of Illinois has found that catch-and-release fishing could still have a negative impact on largemouth bass. The study, published in Environmental Biology of Fishes, revealed that nest-guarding male bass are critically affected by a...

Promiscuous Female Fruit Flies Prevent Male Extinction
2014-04-02 17:14:08

University of Liverpool Female fruit flies with a large number of sexual partners are playing an invaluable role in preventing the extinction of males, research at the University of Liverpool has shown. Scientists have found that flies in the northern parts of the United States are more inclined to have multiple partners in order to reduce the occurrence of an X chromosome which causes the production of only female offspring. This selfish genetic element (SGE) tries to replicate...
