A suspected die-off
of roughly 75 percent of land species didn't accompany the Permian extinction around 252 million years ago, a team of geologists contends.
We have lost half the global population as a result of the mass die-off
in May and I am devastated to learn that one of the transboundary populations is at the brink of extinction.
There is no direct connection between the mass die-off
of saiga antelopes and launches of the Russian rocket-carriers Proton at the Baikonur cosmodrome, said acting chairman of the Aerospace Committee of the Ministry of Investment and Development of Kazakhstan Meirbek Moldabekov.
ROCKAWAY BEACH - Thousands of jellyfish- like creatures have been piling up on the beach in what appears to be a massive die-off
The findings are the latest volley in an ongoing debate over whether an asteroid or volcanism killed off the dinosaurs about 65 million years ago in the mass die-off
known as the K-T extinction.
Practical methods are needed to accurately measure the low, but infective, concentrations and die-off
rates of the pathogens themselves.
Affected and healthy-cohort mussels were collected to characterize the bacterial flora prior to, during, and after a July 2006 die-off
, and during a subsequent die-off
in September 2008.
In the early spring of 2006, an eider duck die-off

in central Alberta, including 50 cm above normal during the major die-off
of moose in late winter-spring 1982 (Table 1).
Low oxygen levels, High C02 and high sweltering heat caused the greatest die-off
of all time.
