Isle Royale National Park's inbred gray wolf population remains dangerously low for a third consecutive year, while the moose on which they feed have doubled during the same period — trends that could lead to long-term problems for the Lake Superior archipelago's ecosystems, scientists said Wednesday.
Only nine wolves roamed the park this winter — one more than the eight recorded last year, which was the lowest total since wildlife biologists began observing the relationship between Isle Royale wolves and moose in the late 1950s. The study is the world's longest of a predator-prey relationship in a closed ecosystem.Full Story

Earthlings get their first solar eclipse of the year Tuesday. But you have to be well south of the equator to see it.
The solar eclipse will be visible to skygazers in Antarctica, Australia, and the southern Indian Ocean about 0600 GMT (2 a.m. EDT). It's one of two solar eclipses in 2014, when the moon lines up between Earth and the sun. This one is a rare type of annular eclipse, meaning the sun will appear as a ring around the moon.Full Story

The smallest and least known of Spain's Canary Islands, El Hierro, is making a splash by becoming the first island in the world fully energy self-sufficient through combined water and wind power.
A wind farm opening at the end of June will turn into electricity the gusts that rake the steep cliffs and green mountains of the volcanic island off the Atlantic coast of Africa.Full Story
A German wildlife rescue project is deploying small aerial drones to find and protect young deer hiding in tall grass from being shredded by combine harvesters cutting hay in spring.
The pilot project has shown great promise in spotting the young animals, about 100,000 of which fall victim in Germany every year to the large agricultural machines, said project spokesman Rolf Stockum on Friday.Full Story
