Cichlid fish genome helps tell story of adaptive evolution
(Phys.org) —Roughly 40 million years ago, a handful of species of fish from the Nile River went into three lakes in Africa and experienced an unusual flurry of evolution. In one of these lakes as many as ...
Specialized species critical for reefs
One of Australia's leading coral reef ecologists fears that reef biodiversity may not provide the level of insurance for ecosystem survival that we once thought.
Sequencing of five African fishes reveals diverse molecular mechanisms underlying evolution
In an effort to understand the molecular basis of adaptation in vertebrates, researchers sequenced the genomes and transcriptomes of five species of African cichlid fishes. A research team led by scientists at the Broad Institute ...
Climate change will threaten fish by drying out Southwest US streams, research predicts
Fish species native to a major Arizona watershed may lose access to important segments of their habitat by 2050 as surface water flow is reduced by the effects of climate warming, new research suggests.
Lionfish characteristics make them more 'terminator' than predator
New research on the predatory nature of red lionfish, the invasive Pacific Ocean species that is decimating native fish populations in parts of the Caribbean Sea and Atlantic Ocean, seems to indicate that ...
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 ...
