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.

The deeper these octopuses live, the wartier their skin

Deep beneath the ocean's surface, surprisingly cute pink octopuses creep along the seafloor. Some of them have super warty skin, and some are smooth. Scientists weren't sure if these octopuses were even members of the same species, and they didn't know how to explain the differences in the animals' looks. But a new study shows that the deeper in the ocean the octopuses live, the bumpier their skin and the smaller their bodies.

Another casualty of climate change? Recreational fishing

Another casualty of climate change will likely be shoreline recreational fishing, according to new research. The study finds some regions of the U.S. may benefit from increasing temperatures, but those benefits will be more than offset by declines in fishing elsewhere.

Proximity to paths and roads is a burden for white-tailed sea eagles

A research team has now measured concentrations of the hormone corticosterone and its metabolic products in white-tailed sea eagles in northern Germany and correlated these values with potential causes of stress. They found that the levels of corticosterone in the birds' urine are higher the closer a breeding pair's nest is to paths or roads.
