Diving down below the range of scuba in the Curasub, Smithsonian deep reef explorers discovered a new world where roughly half of the fish had no names. They are calling it the rariphotic.
A comprehensive study on the rhythmicity of limpets -- mobile intertidal molluscs -- employing field and laboratory observations, as well assembling a clock oriented transcriptome -- shows that in the same way that these animals behave with a tidal rhythm, so too are a majority of their genes expressed in a tidal (and not circadian) rhythm, including some genes which were thought to play an important role in circadian clocks/timing.
Researchers explore an alternative pathway to fast-tracking the global recovery of fisheries
When cattle congregate, they're often cast as the poster animals for overgrazing, water pollution and an unsustainable industry. While some of the criticism is warranted, cattle production -- even allowing herds to roam through grasslands and orchards -- can be beneficial to the environment as well as sustainable.
Many studies have shown that larvae of various fish species can be negatively affected by ocean acidification. Acidification is caused by large amounts of carbon dioxide (CO2) entering the seawater from the atmosphere. But CO2 can also influence the food supply for the fish larvae. Researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel investigated how the combination of these effects influences herring larvae. Their results have been published today in the international journal Nature Ecology and Evolution.
Shark Bay seagrass carbon storage hotspot suffers alarming losses after a devastating marine heat wave, according to a study led by ICTA-Universitat Autònoma de Barcelona researchers. The loss of seagrass would have released up to nine million metric tons of carbon dioxide (CO2) into the atmosphere.
US Geological Survey scientists have developed the first laboratory test that picks up traces of manatees' genetic material in waterways. The environmental DNA test shows whether one or more of the elusive marine mammals has been in the area in the past month.
Shark Bay seagrass carbon storage hotspot suffer alarming losses after a devastating marine heat wave, according to a study involving KAUST researchers.
A cheap, safe and effective method of dealing with harmful algal blooms is on the verge of being introduced following successful field and lab tests.
Some of the fishing methods used in today's small-scale fisheries are causing more damage to coral reefs than ever, a new UBC study has found.
