damaged reefs discourage new growth
2014-08-25 03:30:06

Brett Israel, Georgia Institute of Technology Pacific corals and fish can both smell a bad neighborhood, and use that ability to avoid settling in damaged reefs. Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the degraded habitat, according to new research. The study shows for the first time that coral larvae can smell the difference between healthy and damaged reefs when they decide where to settle. Coral reefs are...

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,...

University of Montreal New study on parasitoid reveals that heat favours production of male progeny Whether an insect will have a male or female offspring depends on the weather, according to a study led by Joffrey Moiroux and Jacques Brodeur of the University of Montreal's Department of Biological Sciences. The research involved experimenting with a species of oophagous parasitoid (Trichogramma euproctidis), an insect that lays its eggs inside a host insect that will be consumed by the...

New Species Of Sea Bass Identified Based On Larval, Adult Specimen
2014-05-14 13:14:48

Brett Smith for redOrbit.com - Your Universe Online Thanks to a lot of hard work and a little luck – two scientists from the National Museum of Natural History at the Smithsonian Institution have identified a mysterious larval fish and the same fish in its adult stage as a new species of sea bass. Most fish that live in the ocean have a pelagic larval stage that floats inside the surface or near-surface currents, an ecosystem very distinct from the one they occupy as adults. Two...

Oysters And Crabs 'Stuck In The Middle'

By Angela Herring, Northeastern University Northeastern University ecologist David Kimbro claims to have watched a lot of TV growing up, particularly The Brady Bunch. “You could kind of get a flavor for how an episode was going to turn out based on how Jan or Peter were faring—you know, the middle kids,” said Kimbro, an assistant professor in the Department of Marine and Environmental Sciences. He and his colleagues—associate professor Jon Grabowski and assistant professor...

DAVIS, Calif., April 16, 2014 /PRNewswire-USNewswire/ -- Farmers, including Forest landowners, along California's northern coast, have long been committed to improving fish habitat while running sustainable agriculture operations. The USDA Natural Resources Conservation Service (NRCS) in California will provide $500,000 in financial assistance to help these landowners take additional steps to boost local salmonid and other aquatic-species populations. "Helping local producers...

bass underwater
2014-04-08 05:09:07

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...
