The lowering of the ocean’s pH is making it harder for corals to grow their skeletons and easier for bioeroding organisms to tear them down. Erosion rates increase tenfold in areas where corals are also exposed to high levels of nutrients, according to a study published January 2015 in the journal Geology. As sea level rises, these reefs may have a harder time growing toward the ocean surface, where they get sunlight they need to survive.

Launched in October 2014, Infra (which stands for “International Fugitive Round Up and Arrest”) Terra focuses on 139 fugitives altogether wanted by 36 member countries for crimes including illegal fishing, wildlife trafficking, trade and disposal of waste, logging and trading in illicit ivory.
 

Gushing downpours finally arrived in California last month, when December rains brought some relief to a landscape parched after three years of severe drought. 

But the rain came too late for thousands of Chinook salmon that spawned this summer and fall in the northern Central Valley. The Sacramento River, running lower than usual under the scorching sun, warmed into the low 60s — a temperature range that can be lethal to fertilized 

Chinook, the largest species of Pacific salmon, need cool waters to reproduce. 

As conservationists continue to worry about the possibility of a world without monarchs, they’ve gotten some hope with an announcement from the U.S. Fish and Wildlife Service (FWS) that federal protection may be warranted for these iconic butterflies. In August, the Center for Biological Diversity, Center for Food Safety, Xerces Society for Invertebrate Conservation and monarch scientist Dr. Lincoln Brower filed a legal petition with the FWS seeking protection for monarchs under the Endangered Species Act.

Trawling the seabed doesn't just remove some of the fishes living there; it also makes some of the survivors thinner and less healthy by forcing them to use more energy finding less nutritious food. That's the conclusion of a new paper published in Proceedings of the Royal Society B, based on the work Dr Andrew Frederick Johnson undertook while studying for his PhD at Bangor University.

A trip to Antarctica might not be a dream vacation for everyone, but it’s on the list for many who are clearly willing to trek to there. While tourists are busy exploring the scenery and greeting the penguins who live there, scientists are raising concerns about how exposure to us could increase their risk of contracting infectious diseases. Scientists and disease experts believe the immune systems of penguins, and other species in the region, are less able to deal with pathogens that are commonplace in the rest of the world because they’ve been isolated for so long with few visitors.

Christmas came early this year for gray wolves thanks to an awesome ruling handed down by a federal judge that immediately reinstated federal protection for them in the Great Lakes region.

The ruling affects wolves in Michigan, Minnesota and Wisconsin, and, unless overturned, will stop these three states from holding any more hunting and trapping seasons, which is expected to protect an estimated 3,700 wolves.

The world's mussel population could be under threat as rising CO2 levels in atmosphere and oceans makes their shells weaker and more brittle shells - making them more vulnerable to stormy seas, and predation.

Weddell seals have biological adaptations that allow them to dive deep--as much as of hundreds of meters--while hunting, but also an uncanny ability to find the breathing holes they need on the surface of the ice. Now, researchers supported by the National Science Foundation (NSF) believe they have figured out how they do it--by using the Earth's magnetic field as a natural GPS. "This animal, we think, may be highly evolved with an ability to navigate using magnetic sense in order to find ice holes some distance apart and get back to them safely," explained Randall Davis of the Department of Marine Biology at Texas A&M University. If the hypothesis turns out to be true, it would represent the first evidence of such a trait in a marine mammal.

Scientists studying the distribution of four commercial and recreational fish stocks in Northeast U.S. waters have found that climate change can have major impacts on the distribution of fish, but the effects of fishing can be just as important and occur on a more immediate time scale. The four species studied– black sea bass, scup, summer flounder, and southern New England/Mid-Atlantic Bight winter flounder – have varied in abundance and have experienced heavy fishing pressure at times over the past 40 years.
