Excerpts;

Seagrass beds are so effective in protecting tropical beaches from erosion, that they can reduce the need for regular, expensive beach nourishments that are used now. Biologists and engineers from the Netherlands and Mexico describe experiments and field observations around the Caribbean Sea…

Larger marine animals at higher risk of extinction, and humans are to blame, Science Daily (09-14-2016)
In today’s oceans, larger-bodied marine animals are more likely to become extinct than smaller creatures, according to a Stanford-led report. It’s a pattern that is unprecedented in the history of life on Earth, and one that is likely driven by human fishing…

Excerpts;

With sea ice reduced, polar bears in the Arctic are spending more time on land, leading to increased attacks on people. Concerned Inuit communities want to increase hunting quotas, but researchers are testing new technologies they hope will reduce these often deadly confrontations…

Busy Times at the World’s Largest Polar Bear Prison; The Atlantic (12-16-2016)
Sea ice has done some extremely odd things in 2016, as climate change is reshaping the Arctic faster than the rest of the planet. According to a new study, there’s a 71 percent chance that the global polar bear population will fall by over 30 percent in the next three decades. The only hope for the polar bear is to reduce carbon emissions, in the hope that the runaway pace of Arctic warming will eventually stabilize and reverse…

Excerpts;

Artificial intelligence and extensive satellite imagery have allowed researchers to map the world’s intertidal zones for the first time, revealing a significant loss of the crucial ecosystem. The study has shown that global foreshore environments declined by up to 16 percent between 1984 and 2016…

What does a persistent bloom of algae indicate about the health of the planet?

Excerpts;

While the harmful algae known as red tide have historically been common in warm waters like those of the Gulf of Mexico, the troublesome blooms are no longer seasonal. The algae kill marine animals and make life miserable for beachgoers.

“Regions of harmful algal blooms across the globe have increased in size, number and frequency,” Savarese says. “This isn’t just a Florida problem or a Gulf of Mexico problem, this is a planetary problem…”

How Hurricanes Michael, Florence May Have Spread Nonnative Species


The flathead catfish, which is native to the Mississippi Basin, has been recorded in the Carolinas and could be spread by Hurricane Florence’s floodwaters. It could affect the abundance of popular native fish like sunfish. Credit: Eric Engbretson, USFWS, public domain.

Excerpts;

Hurricane Florence’s floodwaters and Hurricane Michael’s storm surge caused obvious devastation to natural areas, but a subtler set of harms is harder to see. Potentially destructive nonnative aquatic species, such as fast-growing plants that can choke waterways and hungry snails that can attack crops, can fan out across the landscape in the storms’ waters, spreading unseen and becoming hard to eradicate…
