Bears pack on fat when preparing to hibernate each winter. To avoid the health risks often associated with human obesity, the bears have specialized gut microbiota that takes in more energy from food in the summer.
Snowshoe hares typically shed their brown summer coats to blend in with the snowy scenery of the winter. However, when there is no snow, these mismatched animals have no place to hide and increase their chances of being spotted by a predator.
Although the appearance of plants and trees are known to change between seasons, a new study from Temple University offers recommendations for designing landscapes in temperate climates that people can enjoy year-round. This includes planting evergreens and plants that produce colorful berries.
Plants and animals alter their behaviors based on the seasons. Humans, it turns out, are no different. Here are just a few ways we change with the season.
Deciduous trees along rivers and streams provide protection from damaging solar radiation and valuable foliage every autumn. Fallen leaves act as a vital food source for insects, and keeping insect populations healthy could ultimately help river ecosystems combat climate change, researchers reveal in a new study.
European rollers are facing deforestation in Europe and their yearly winter migration to Africa is getting tougher each year. Now researchers have identified key areas that will help conservationists better protect the threatened species.
Among all bat species, African straw-colored fruit bats are record-holding flyers. This enables them to successfully forage for food, while spreading seeds and pollen over wide-spread areas of Africa.
Americans have depended on groundhogs for tips on when spring will arrive for over two centuries; now scientists say they can do better with new modeling software. Here's their prediction for the coming year.
It's allergy season, and as if everyone wasn't sneezing and wheezing enough, now new research says that allergy attacks could increase with climate change as the notorious ragweed pollen spreads.
With summer nearly a month away, there's a reason everyone is anticipating its arrival. The sun is always shining, school's out, you lay on the beach and tan, and you just feel better. Well, the latter may be because people are generally healthier in the summer.
Seasons on Earth are determined by how and when our big blue world is tilted towards the Sun. The Sun then, as it is at the center of this process, could not possibly have seasons of its own. Now new research has revealed that this is not necessarily true, for the star actually undergoes predictable swings between times of relative calm and times of intense solar activity.
Spring officially started last Friday evening, even if a good majority of folks in the north were still seeing snow on the ground and ice on the roads. And while these last legs of chilly weather may seem to indicate that spring has been pushed back, the reality is that the season is actually shortening, with summer expected to come earlier than ever before this year.
A team of astronomers has discovered a rare planet called Kepler-432b that boasts some extreme seasons unlike Earth's own spring, summer, fall and winter, new research finds.
The same time every year, some people across the globe suddenly find themselves severely depressed. This is called seasonal affective disorder (SAD) and it has left professionals scratching their heads for years. Now a team of researchers have discovered that SAD could be caused by increased levels of the serotonin transporter protein.
