Sixth-grader proves invasive species of ocean fish can thrive in low saline water
Beautiful but a threat: Tropical fish invasion destroys kelp forests
The migration of tropical fish as a result of ocean warming poses a serious threat to the temperate areas they invade, because they overgraze on kelp forests and seagrass meadows, a new study concludes.
Climate change accelerates hybridization between native and invasive species of trout
(Phys.org) —Scientists have discovered that the rapid spread of hybridization between a native species and an invasive species of trout in the wild is strongly linked to changes in climate.
Scientists link unusual fish larva to new species of sea bass from Curacao
Identifying larval stages of marine fishes in the open ocean is difficult because the young fishes often bear little or no resemblance to the adults they will become. Confronted with a perplexing fish larva ...
Researchers find blind fish use novel type of navigational aid
Study shows heart abnormalities in fish embryos exposed to Deepwater Horizon oil
A new study showed that several Gulf of Mexico fish embryos developed serious defects in heart development following exposure to crude oil from the Deepwater Horizon oil spill. The study is the first to analyze ...
Plan to delist gray wolf endangers other threatened species, researchers find
The federal government's proposal to discontinue protection for the gray wolf across the United States could have the unintended consequence of endangering other species, researchers say.
Sandcastle-building fish offer evolution clue
(Phys.org) —In Lake Malawi, East Africa, there are around 200 different species of cichlid fish that once or twice a year build large sand structures (known as bowers) on which the fish mate. Each different ...
New species of giant Amazonian fish reported
(Phys.org) —A new species of the giant fish arapaima has been discovered from the central Amazon in Brazil, raising questions about what other species remain to be discovered and highlighting the potential ...
Global study reveals new hotspots of fish biodiversity
Teeming with millions of species, tropical coral reefs have been long thought to be the areas of greatest biodiversity for fishes and other marine life—and thus most deserving of resources for conservation.
Taking over the oceans: Adult fish characteristics predict a species' dispersal
As fish disperse to find new habitats, scientists have developed a new model to judge a species' success in colonising new places. The study has shown some surprising results, suggesting that success can ...
The coelacanth leads a monogamous life
Scientists have successfully analyzed the genetic make-up of the offspring of pregnant coelacanth females for the first time. They found that the likelihood that the offspring is fathered by one single individual ...
Researchers claim evidence suggests cichlid fish evolved long after Gondwana rifted apart
In whole-lake experiment, have invasive crayfish met their match?
Four years ago, UW-Madison researchers wrapped up a multi-year effort to dramatically reduce the population of a destructive invasive species in a northern Wisconsin lake.
