Between April 2020 and this April, losses across the country averaged 45.5 percent according to preliminary data from the Bee Informed Partnership, a collaboration of researchers that has conducted the annual bee loss survey for 15 years.
Why did species go extinct at the end of the Triassic period? Huge and widespread volcanic eruptions triggered the end-Triassic extinction. Some 200 million years ago, an increase in atmospheric CO2 caused acidification of the oceans and global warming that killed off 76 percent of marine and terrestrial species on Earth.
What plants went extinct in the Triassic period? Many plant families were culled; giant club mosses and horsetails also went extinct during the late Permian, and new forms evolved during the Triassic. The Triassic was the beginning of a boom in conifers and cycadophytes. Leptocycas was a cycad, a primitive seed plant from the late Triassic period.

There has been many reasons for hunting wolves. At first wolves were hunted for their thick winter fur.
