Views: The Beautiful And Bizarre ‘Eyes” Of Animals

“The cornea, which in fish is simply a transparent protective cover for the eye, became an image-forming structure in its own right,” wrote the late Michael Land, a biologist at the University of Sussex in England, in a 2005 study in the journal Current Biology, “because it now had air on one side and water on the other.”

Some organisms have kept basic structures—flatworms and mollusks still have their simple pit eyes—while others sprouted mirrored components, elaborate pupil dynamics and arrangements that let their owner see above and below a waterline simultaneously. Even in animals that rely primarily on sensations besides sight, incredible eye features persist.

Animals & Wildlife: ‘The Evolution Of Bears’

Bears are able to live and sometimes thrive from the North Pole to the tropical rainforests around the equator and although they are largely confined to the forests nowadays, in the not too distant past they dominated grassy plains as well. And in overcoming the challenges of each new habitat they migrated into presented, they have evolved to drastically change diets. Bears evolved from small carnivorous animals and yet have become omnivorous, insect eaters, or have a diet occupied entirely of plant foods. So how have bears been able to evolve to eat almost any food in a very small amount of time.

Wildlife: The ‘Gray Wolves’ Of Yellowstone (Video)

Watch the majestic wolves of Yellowstone National Park. Videographer: Justin Grubb.

Gray wolves were reintroduced into Yellowstone National Park in 1995, resulting in a trophic cascade through the entire ecosystem. After the wolves were driven extinct in the region nearly 100 years ago, scientists began to fully understand their role in the food web as a keystone species.

Ecology: Benfits Of 50% Of Serengeti Grasslands Burning Each Year (Video)

After receiving twelve hours of solar energy every day, the Serengeti grasslands become a tinderbox, just waiting to be lit.

The vast majority of the African fires currently burning seem to be in grasslands, in exactly the places we expect to see fires at this time of year. These fires are usually lit by cattle farmers as part of their traditional management of the savannahs where their animals graze. Some fires are started to stimulate new growth of nutritious grass for their animals, others are used to control the numbers of parasitic ticks or manage the growth of thorny scrub.

Without fires, many savannahs (and the animals they support) wouldn’t exist, and lighting them is a key management activity in many of the iconic protected areas of Africa. For instance the Serengeti in Tanzania is known worldwide for its safari animals and awe-inspiring wildebeest migration – and our work shows that around half of its grasslands burn each year.
