Scientists Say Arctic Sea Ice Levels Linked With Gray Whale Mass Die-Off Events
Scientists Say Arctic, Sea Ice Levels Linked With , Gray Whale Mass Die-Off Events.
LiveScience reports that scientists may have determined
the reason behind a series of mass deaths among
gray whales in the northeastern Pacific Ocean.
.
According to a new study, scientists have linked recent
major mass mortality events with Arctic sea ice levels.

According to a new study, scientists have linked recent
major mass mortality events with Arctic sea ice levels.
.
Three major die-off events have
impacted gray whales off the coast
of North America since the 1980s.
Those events reduced the whale population
by 15% to 25% each time they occurred,
killing over 2,000 gray whales.
In 2019, the latest die-off event
started with over 70 gray whales washing
ashore dead in only six months.
Since then, a total of 688 are known
to have died, while the cause of
the event has remained unclear.
These are extreme population swings
that we did not expect to see in a large,
long-lived species like gray whales, Joshua Stewart, Study lead author and assistant professor at Oregon State University's Marine Mammal Institute, via LiveScience.
According to the new study, published in the journal 'Science,' changing conditions and fluctuations in sea ice levels in the Arctic may be responsible for these events.
.
Sea ice cover and the amount of
available food may dictate how
the gray whale population fares.
.
When the availability of their prey
in the Arctic is low and the whales
cannot reach their feeding areas because
of sea ice, the gray whale population
experiences rapid and major shocks, Joshua Stewart, Study lead author and assistant professor at Oregon State University's Marine Mammal Institute, via LiveScience.

A lawsuit filed by the mother of the late Russian opposition figure, Alexei Navalny, alleging inadequate medical care during his time in the Arctic penal colony where he passed away, has been dismissed. The court in the town of Labytnangi, near the penal colony, rejected the suit, citing Navalny's absence as the plaintiff. Ivan Zhdanov, a former aide to Navalny, expressed dismay over the decision, highlighting Navalny's history of filing lawsuits regarding medical care in prisons. The dismissal, Zhdanov noted, comes with a tone of mockery, given Navalny's tragic demise.

During a nighttime training flight, two Japanese navy helicopters, each carrying four crew members, crashed in the Pacific Ocean south of Tokyo, possibly colliding with each other, according to the country's defence minister on Sunday. Tragically, one crew member recovered from the waters was later declared deceased, while rescuers continued to search for the remaining seven who were still missing. The incident occurred late Saturday near Torishima island, approximately 600 kilometres (370 miles) south of Tokyo, involving two SH-60K choppers from the Maritime Self-Defense Force, Defense Minister Minoru Kihara informed reporters.

The seven-phase Lok Sabha polls season will witness an unprecedented rise in the heatwave in most parts of the country, the India Meteorological Department warned here on Monday. While above-normal temperatures are likely almost all over the country, 10-20 days of heatwave is expected between April and June in different parts against normal of 4-8 days. The most heatwave prone areas are Gujarat, central Maharashtra and north Chhattisgarh, Odisha and Andhra Pradesh. “More heatwave days are expected in an El Nino year. The El Nino (an unusual rise of temperature in the Pacific Ocean with impacts all over the world) is still there in April-May even though it is receding and may become neutral by June,” Mrutyunjay Mohapatra, director general of meteorology at the IMD said.
What are El Nino and La Nina and how do they affect the weather conditions?

Study Reveals First Case , of an American Dolphin , Diagnosed With Bird Flu.
'Newsweek' reports that a new study has found
that a Florida dolphin was discovered with
a "highly pathogenic" form of bird flu.

The case is the first cetacean ever recorded

The case is the first cetacean ever recorded
in North America with highly pathogenic
avian influenza virus (HPAIV).
The study warns that a highly contagious
bird flu "could be catastrophic"
for cetacean species.
In March of 2022, a dolphin was found
"in distress" in a Dixie County canal and died
shortly after the arrival of a rescue team. .
A postmortem revealed that the dolphin suffered
from a number of health problems, including
leptomeninges disease and brain inflammation.
We still don't know where
the dolphin got the virus and
more research needs to be done, Richard Webby, Director of the World Health
Organization Collaborating Center for Studies
on the Ecology of Influenza in Animals and Birds at
St. Jude Children's Research Hospital, via 'Newsweek'.
After first being detected in North America
in 2021, the virus has been spreading
among birds and other mammals.

According to researchers, harbor seals and grey seals
in the area had died from the same virus. A small
amount were also found to have neurological symptoms.
So far, seals and sea lions have
been the primary mammal species
to be impacted by the disease. .
'Newsweek' reports that the recent study highlights the
importance of learning more about the virus in order to
potentially prevent it from spreading to further species.
