Hibernating Grizzly Bears Maintain Circadian Rhythms, Study Finds

A genetic study led by researchers at Washington State University (WSU) has found that grizzly bears maintain their circadian rhythm even during hibernation, highlighting the importance of circadian rhythms in the metabolism of organisms. The study revealed that bears' energy production still follows a daily pattern during hibernation, although the amplitude of the energy production is reduced. The peak of energy production occurs later in the day during hibernation. Researchers believe that altering the circadian rhythm during hibernation helps bears conserve energy and survive without food for months.

"Republican Opposition and Conservation Concerns Surround Biden's Grizzly Bear Release Plan"

Republican Rep. Dan Newhouse has introduced legislation to block a federal proposal by the Biden administration to release grizzly bears in the North Cascades National Park in Washington state. The proposal, which aims to restore the threatened apex predator species, has been met with opposition from local lawmakers and residents who are concerned about public safety and the negative impacts on communities. The legislation would force the Department of the Interior to withdraw the proposed rule and draft environmental impact statement. The Biden administration's plan includes options to actively restore grizzly bear populations, with the goal of establishing a population of around 200 bears in the coming decades.

"Insatiable Grizzlies: Devouring 40,000 Moths Daily"

Grizzly bears in north-west Wyoming rely on army cutworm moths as a crucial food source during the summer months, with some bears consuming up to 40,000 moths per day. The moths, known as "bear butter" due to their high fat content, migrate to the mountain peaks by the hundreds of millions each year, providing a high-calorie buffet for the bears. As other food sources decline due to climate change, the stability of the moth population becomes increasingly important for the grizzlies' recovery. However, human interference and the climate crisis pose threats to this unique relationship.

Close Encounters: Hikers Face Off with Grizzly Bears in Banff

Hikers in Banff National Park had an "intense" experience when they were stalked by a grizzly bear and her cub for several minutes. The bears followed closely behind as the hikers made their way to Consolation Lake, but did not attack. This behavior is unusual as grizzly bears typically avoid groups of people. The encounter serves as a reminder to be prepared and carry bear spray while hiking in bear country.

"Grizzly Attack Sparks Renewed Bear Overpopulation Debate Near Yellowstone"

The recent fatal grizzly bear attack near Yellowstone National Park has reignited the debate over whether there are too many bears in the area and whether they should be removed from the Endangered Species Act. Despite the growing population of grizzlies, statistics show that the likelihood of being killed by a grizzly is similar to being killed by a falling tree. Experts argue that coexistence between humans and bears is possible, as demonstrated in the greater Yellowstone ecosystem. However, some elected leaders in the region are calling for delisting the bears, while others emphasize the importance of adapting to their presence and serving the ecological integrity of the area. The U.S. Fish and Wildlife Service is currently analyzing grizzly recovery, and politicians have introduced legislation to delist the bears through Congress.

Grizzly Emerges from Hibernation in Captivating Video

A park in British Columbia captured the moment a grizzly bear named Boo emerged from hibernation after several months. Grizzly bears slow their metabolism and heart rate during hibernation and do not eat, drink, or defecate. Researchers studying brown bears in Sweden found that some bears are more predatory than others, with one 13-year-old female killing 38 reindeer calves and 18 young moose after waking up from hibernation. The study shows differences in individual bears' predatory behavior and how this helps explain individual variation in their habitat selection.
