Mountain Pikas Eat Moss to Survive Climate Changes Pikas are small mammals closely related to rabbits and hares that are native to cold, alpine climates in North America, Asia and Eastern Europe. Pikas are very sensitive to heat, dying if they spend more than two hours above 78 degrees Fahrenheit, so cold climate is important to their survival. And sadly, as increasing temperatures continue to play a role in our changing climate, pikas have gone extinct in some mountain ranges and moved to higher peaks in others in the American West. However, researchers have also discovered pikas living in rockslides near sea level in Oregon. But how is this species surviving in these warmer gorge areas when they are dependent on colder weather? Well, biologists claim pikas survive hot weather simply by eating moss.
More than 40% of Scotland's energy demand is now met by renewables Scotland’s renewable electricity output has reached record-high levels, according to official statistics released today.
The figures, published by the Department of Energy and Climate Change, show that renewables met a record-breaking 40.3 per cent of gross electricity consumption in 2012, confirming that Scotland is on track to meet its interim target of 50% by 2015.
Amazing study shows how dinosaurs walked For the first time scientists have learnt how the largest four-legged dinosaurs got from A to B.
The new research, published in Plos ONE, wanted to understand how one of the biggest animals to have lived on Earth, the Argentinosaurus, walked.
The Argentinosaurs, at 80 tonnes and 40m long was the equivalent of fifteen elephants, and scientists were unsure how such a big animal could even move.
Upper atmosphere mystery solved by UCLA researchers University of California, Los Angeles (UCLA) researchers have conducted detailed modeling to reveal that characteristics of natural very low–frequency radio waves known as "chorus" in the Earth's upper atmosphere are primarily responsible for the observed relativistic electron build-up showing that radial diffusion is not responsible for the observed acceleration during an atmospheric storm. This newfound knowledge and procedural understanding will influence our activities throughout the universe.
New Tapir Species Discovered In what will likely be considered one of the biggest (literally) zoological discoveries of the Twenty-First Century, scientists today announced they have discovered a new species of tapir in Brazil and Colombia. The new mammal, hidden from science but known to local indigenous tribes, is actually one of the biggest animals on the continent, although it's still the smallest living tapir. Described in the Journal of Mammology, the scientists have named the new tapir Tapirus kabomani after the name for "tapir" in the local Paumari language: "Arabo kabomani."
