The late formation of Arctic sea ice may be forcing some hungry and desperate polar bears in northern Manitoba to resort to cannibalism. “A big male polar bear separated a young cub from its mother and had its way with the cub,” some tourists said. “But the whole time, while that mother polar bear watched and witnessed, and actually after the big bears left, she still tried to take care of it. It was difficult for us to witness and it was difficult for us to hear about and learn about. Retired Environment Canada biologist Ian Stirling, who has studied bears all over the arctic, said evidence suggests the cubs are being killed for food, not just so the male can mate with the sow.

Mammatus clouds —  also known as mammatocumulus (meaning “mammary cloud” or “breast cloud”), is a meteorologicalterm applied to a cellular pattern of pouches hanging underneath the base of a cloud. The name mammatus, derived from the Latin mamma (meaning “udder” or “breast”), refers to a resemblance between the characteristic shape of these clouds and the breast of a woman.

magicalnaturetour: Long eared jerboa ~ The long-eared jerboa (Euchoreutes naso) is a terrestrial jumping rodent found in southern parts of Mongolia and north-central areas of China. The species is primarily nocturnal, spending the daylight hours in underground tunnels, and insectivorous. The main threat to the species is thought to be human disturbance of its habitat, but very little is currently known about the species. Words and picture via Wildlife Extra :)

Life scientists view biodiversity through a whole new dimension: Body size, feeding rates

ScienceDaily (May 31, 2012) — How can blue whales, the largest animals on the planet, survive by feeding on krill, shrimp-like creatures that are the size of a penny? According to UCLA life scientists, it’s all a matter of dimensions.

In findings published May 30 in the journal Nature, the researchers demonstrate for the first time that the relationship between animals’ body size and their feeding rate — the overall amount of food they consume per unit of time — is largely determined by the properties of the space in which they search for their food.

An animal searching for food in a three-dimensional space, like the ocean or sky, is likely to consume much more than a similarly sized animal searching in a flat, two-dimensional space, like a savannah or a sea bed, they found.
