bear : any of a family of large heavy mammals of America and Eurasia that have long shaggy hair, rudimentary tails, and plantigrade feet and feed largely on fruit, plant matter, and insects as well as on flesh — Webster
Bears are carnivoran mammals of the family Ursidae. Bears are classified as caniforms, or doglike carnivorans. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout the Northern Hemisphere and partially in the Southern Hemisphere. Bears are found on the continents of North America, South America, Europe, and Asia. Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails.
While the polar bear is mostly carnivorous, and the giant panda feeds almost entirely on bamboo, the remaining six species are omnivorous with varied diets. With the exception of courting individuals and mothers with their young, bears are typically solitary animals. They may be diurnal or nocturnal and have an excellent sense of smell. Despite their heavy build and awkward gait, they are adept runners, climbers, and swimmers. Bears use shelters, such as caves and logs, as their dens; most species occupy their dens during the winter for a long period of hibernation, up to 100 days. — Wikipedia

- The next generation of biodiversity conservation...on October 22, 2020 at 6:00 pm
Nearly three decades have passed since world leaders agreed to reverse biodiversity loss. It hasn't gone according to plan. This year, the current decade of biodiversity conservation targets are set to expire well short of the goal line. The world needs to change strategies if we are to have any hope for biodiversity. A global group of scientists has provided advice for a more successful replacement scheme, a quite literal "next-generation" plan being hashed out by the Convention on Biological […]

Feral hogs are among the most damaging, invasive animals that you probably haven't heard of. University of Delaware's Center for Experimental and Applied Economics researcher Sean Ellis hadn't heard about them either. But, after his economics research on these hogs and how to address the many problems they present, he's unexpectedly become a hog expert. Along with UD's Kent Messer, Ellis is a co-author of new feral hog research published this October in Applied Economic Perspectives and Policy.
- Tradition of petrified birds in the Dome of the...on October 20, 2020 at 8:11 pm
On the southern exterior wall of the Dome of the Rock, a very important Islamic shrine in Jerusalem's Old City, there are two marble slabs, both carved from the same stone and placed side by side to form a symmetrical pattern, that depicts two birds. In a recent article published in the Journal of Near Eastern Studies, "Solomon and The Petrified Birds on the Dome of the Rock," author Elon Harvey explores the history of this marble decoration and describes how different narratives about Solomon […]
- The evolutionary advantage of being friendlyon October 20, 2020 at 1:17 pm
We've all heard the term "survival of the fittest," which scientist Charles Darwin famously coined to explain how organisms with heritable traits that give them an advantage—such as avoiding predators or beating out others for the chance to mate—are able to survive and pass on these advantageous traits to their offspring.
