Survival strategy found in living corals which was only seen in fossil records

Some corals can recover after massive mortality episodes caused by the water temperature rise. This survival mechanism in the marine environment — known as rejuvenation — had only been described in some fossil corals so far. A new study reveals the first scientific evidence of the rejuvenation phenomenon in vivo in Cladocora caespitosa coral colonies, in the marine reserve in Columbrets, in the coast of Castellón.

Many cooks don't spoil the broth: Manifold symbionts prepare the host for any eventuality

Deep-sea mussels, which rely on symbiotic bacteria for food, harbor a surprisingly high diversity of these bacterial 'cooks': Up to 16 different bacterial strains live in the mussel's gills, each with its own abilities and strengths. Thanks to this diversity, the mussel is prepared for all eventualities, researchers report.

much attention has been given to the growth of the 'Blue Economy' — a term which refers to the sustainable use of ocean and marine resources for economic growth, jobs, and improved livelihoods. Ocean resources are viewed as lucrative areas for increased investment, including in fisheries, aquaculture, bio-prospecting, renewable energy, oil and gas, and other businesses. Ensuring that socially equitable and sustainable development occurs should be the mandate of governments and industry, maintain an international group of researchers, led by UBC.

New tool enables Nova Scotia lobster fishery to address impacts of climate change

October 11, 2019 0 Comments Climate, Environmental Awareness, Fish, Fisheries, Global Warming, Marine Biology, Nature, Oceanography

Researchers use long-term survey data sets and climate models to help fishing communities plan for a warmer ocean. Researchers have developed a tool that incorporates projected changes in ocean climate onto a geographic fishery management area. Now fishermen, resource managers, and policy-makers can use it to plan for the future sustainability of the lobster fishery in Nova Scotia and Canadian waters of the Gulf of Maine.

Solution to Ice Age ocean chemistry puzzle

New research into the chemistry of the oceans during ice ages is helping to solve a puzzle that has engaged scientists for more than two decades. At issue is how much of the CO2 that entered the ocean during ice ages can be attributed to the 'biological pump', where atmospheric carbon is absorbed by phytoplankton and sequestered to the seafloor as organisms die and sink.

Reef fish caring for their young are taken advantage of by other fish

Among birds, the practice of laying eggs in other birds' nests is surprisingly common. This phenomenon, known as brood parasitism, was unknown in coral reef fish because most marine fish don't provide any parental care at all. Now, however, biologists studying an unusual kind of coral reef fish that does care for its young have found that, sure enough, other fish are taking advantage of this to get free parental care for their offspring.

A unique study sheds light on the ecology of the glacial relict amphipod Gammaracanthus lacustris

October 9, 2019 0 Comments Biology, Ecology Research, Endangered Animals, Extreme Survival, Fish, Fisheries, Marine Biology, Nature

The glacial relict amphipod Gammaracanthus lacustris only occurs in deep and cold waters. A new study produced new information on the life cycle and ecology of this rare amphipod. G. lacustris is adapted to cold water and would probably not survive in rising water temperatures due to climate change.
