Researchers capture video of freshwater fish grabbing birds out of the air
Slow-evolving elephant shark genome is first to be sequenced from cartilaginous fish
A team of researchers including SF State Assistant Professor of Biology Scott Roy has sequenced the entire genome of the elephant shark, uncovering several features that may shed light on the evolution of ...
Farm salmon pose clear reproductive threat to wild gene pools
Farmed salmon show full reproductive potential to invade wild gene pools and should be sterilised - according to new research from the University of East Anglia (UEA).
Ninety-five per cent of world's fish hide in mesopelagic zone
An international team of marine biologists has found mesopelagic fish in the earth's oceans constitute 10 to 30 times more biomass than previously thought.
Competition breeds new fish species, study finds
Competition may play an important role during the evolution of new species, but empirical evidence for this is scarce, despite being implicit in Charles Darwin's work and support from theoretical studies.
Study of jaw mechanics shows tetrapods still fed underwater
A study of the jaws of one of the earliest known limbed vertebrates shows the species still fed underwater, not on land.
A battery small enough to be injected, energetic enough to track salmon
(Phys.org) —Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon through rivers in the Pacific Northwest and around ...
Genetic chip will help salmon farmers breed better fish
Atlantic salmon production could be boosted by a new technology that will help select the best fish for breeding.
Fish biomass in the ocean is ten times higher than estimated
With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean. However, a team of researchers with the participation of the Spanish National Research ...
Link confirmed between salmon migration, magnetic field
A team of scientists last year presented evidence of a correlation between the migration patterns of ocean salmon and the Earth's magnetic field, suggesting it may help explain how the fish can navigate across ...
Seabirds' personalities determine feeding styles
Seabirds have distinct individual personalities that affect where they feed and how likely they are to prosper, a pair of recent studies suggests.
Evidence that land animals evolved the ability to breathe air as ancient fish
(Phys.org) —In a major evolutionary discovery, Flinders University palaeontologist Professor John Long (pictured) has found evidence to show that four-legged animals first developed the ability to breathe ...
How the genetic blueprints for limbs came from fish
A study led by Denis Duboule shows that limbs emerged during evolution by modernisation of a preexisting DNA structure.
Risky behaviour more likely in male fish than female
Male stickleback fish are bolder and more willing to take risks than females, say scientists.
