NATIONAL MONITOR - NOAA TO DOUBLE SIZE OF MARINE RESERVE AREA IN SAN FRANCISO BAY full article
Excerpt:
The Cordell Bank National Marine Sanctuary, originally designated in 1989, is located north of San Francisco will increase to 1,286 square miles from its present 529 square miles. The Culf of the Farallones National Marine Sanctuary, designated in 1981, located due west of San Francisco will expand to 3,295 from its current 1,282 square miles. ...
According to a statement from the White House, “NOAA’s action today reflects President Obama’s strong commitment to protecting our oceans and coasts. The ocean provides food, jobs, and opportunities for tourism and recreation for Americans all over the country. But the ocean is in trouble, facing serious threats from carbon pollution to overfishing. That’s why the President has taken action throughout his Administration to promote marine conservation and give Americans a voice in protecting areas of the sea that matter most to them.”

AFTER MENOPAUSE FEMALE KILLER SHARKS BECOME LEADERS
NBC - LEADERSHIP ROLES OF KILLER SHARKS AFTER MEMOPAUSE full article by
Linda Carroll.
EXCERPTS: After observing 102 killer whales in the wild, British researchers have determined that female killer whales become key leaders in their pods only after they age out of fertility...

Menopause, it turns out, is quite rare in the animal kingdom: human women and only two whale species outlive their reproductive lives in a major way, says the study's lead author, Lauren Brent, an associate research fellow in animal behavior at the University of Exeter. Female killer whales typically become mothers between the ages of 12 and 40, but they can live for more than 90 years as compared to the males who rarely make it past 50.
The evolutionary reason, Brent says, is probably similar across the species. Older females become valued for their accumulated knowledge and wisdom. ...

SEA LION EMERGENCY - VOLUNTEER? -THOUSANDS WASHING ASHORE SICK AND DYING - THOUSANDS MORE DEAD ON CHANNEL ISLANDS
SACBEE - ENVIRONMENTAL - SICK STARVING SEA LION PUPS WASH UP IN RECORD NUMBERS full intense article by Peter Hecht
EXCERPTS:
Along the length of the California coastline, an extraordinary rescue effort is underway. In January and February alone, 1,450 malnourished or dying sea lion pups have washed up on shore – compared with just 68 in the same period last year.
“These are pups that should be nursing on their mothers,” said Dr. Shawn Johnson, director of the veterinary science department at The Marine Mammal Center in Sausalito. “They’re (arriving) extremely emaciated. They have no energy stores. They’re just skin and bones, wasting away and on the brink of death.”
From Sea World in San Diego to the Northcoast Marine Mammal Center in Del Norte County, seven California marine rescue facilities are tube-feeding fish gruel to skeletal pups, helping them learn to catch and digest whole fish and administering vitamins and medication to ward off pneumonia and skin infections....

HUNDREDS OF STARVING BABY SEA LIONS ABANDONED AND ON SHORE - OVERWHELMING RESCUE
SCIENCE WORLD REPORT - PUPS WASHED ASHORE by Catherine Griffin
Excerpts:
"While sea lion pups are usually weaned from their mothers in April, it seems that many of the young mammals have been separated from their parents earlier this year. In fact, it's estimated that about 45 percent of the pups that were born in June at island rookeries off the Southern California coast have now died...
The pups that have washed ashore tend to be extremely underweight and dehydrated. It's a miracle that they make it to the coast at all. That said, experts believe that the pups are using a combination of ocean currents and swimming to make the arduous journey...
Currently, the sea lion strandings are nearly three times higher than the historical average, and two weeks ago, the Pacific Marine Mammal Center declared a state of emergency due how many sick and stranded sea lions were being brought in.

EVOLUTION FAVORS THE BIGGER SEA ANIMALS - PALEOBIOLOGY
FrontLine Desk - EVOLUTION LIKES BIGGER SEA ANIMALS by Robert Anderson
"The research is a strong support for Cope’s rule. The rule is named after the famous paleontologist Edward Cope. It states that that sizes of animals increase over time.
Earlier, scientists were not certain whether the rule is applicable to marine life or not. They believe that land mammals are the only one to observe the cope’s rule.
Jonathan Payne, Standford University Paleobiologists, discussed the study in detail. He informs that scientists were already aware of the fact that sea animals are growing bigger day by day. The current size of the Blue Whale is nearly 1000 times larger as compared to when it was first evolved..."
