Biologists show how the evolution of physical traits can influence behavior
For many male African cichlid fish, the best way to attract a mate is to build a really nice pit or sand castle on a lake bottom.
Fishes' innate food choice could change with the environment
The fact that fish choose their food based on what colours they can see, as opposed to how it tastes, is an inherited trait that could have implications for the evolution in the animal kingdom, new Deakin ...
Study shows cold climate animals may suffer as global temperatures rise
The devil is in the detail
Researchers have looked at a species of fish to help unravel one of the biggest mysteries in evolutionary biology.
Study finds tropical fish moving into temperate waters
Tropical herbivorous fish are beginning to expand their range into temperate waters – likely as a result of climate change – and a new international study documents the dramatic impact of the intrusion ...
Trawling makes for skinny flatfish
Trawling the seabed doesn't just remove some of the fishes living there; it also makes some of the survivors thinner and less healthy by forcing them to use more energy finding less nutritious food.
Top marine scientists call for action on 'invisible' fisheries
To protect our oceans from irreversible harm, governments, conservationists, and researchers around the world must address the enormous threat posed by unregulated and destructive fisheries, say top marine ...
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.
