A research team led by Yale University scientists has for the first time determined the original colors of an ancient moth, based on nearly 50 million-year-old fossils from Germany.
The discovery could help scientists learn the colors of a wide variety of long-extinct creatures, including birds, fishes, and other insects, and shed light on color’s function and evolution. (more…)
*New formula reduces feed costs by 10 percent*
VIDEO: Turkeys Stop Gobbling the Profits
COLUMBIA, Mo. – As feed prices have risen in recent years, feeding turkeys has become more costly than many producers can bear. Satisfying turkeys’ hunger accounts for 70 percent of the cost of producing turkey meat. Now, a researcher at the University of Missouri has produced a cheaper turkey feed, which could fill turkeys’ tummies and producers’ pockets. (more…)
AUSTIN, Texas — An international team of scientists that includes two University of Texas at Austin researchers has found that Ecuador’s Yasuní National Park, which sits on top of massive reserves of oil, is in the single most biodiverse region in the Western Hemisphere.
The announcement is part of a final push for the Yasuní-ITT Initiative at the United Nations General Assembly. The initiative proposes that Ecuador receive compensation for half of the revenues the nation would lose by protecting the estimated 846 million barrels of oil that lie beneath the forest. (more…)
Birds may have a more highly developed sense of smell than researchers previously thought, contend scholars who have found that penguins may use smell to determine if they are related to a potential mate.
The research by the University of Chicago and the Chicago Zoological Society, which manages Brookfield Zoo, shows how related birds are able to recognize each other. The study, published Wednesday, Sept. 21 in the article, “Odor-based Recognition of Familiar and Related Conspecifics: A First Test Conducted on Captive Humboldt Penguins (Spheniscus humboldti),” in the journal PLoS ONE, could help conservationists design programs to help preserve endangered species.
“Smell is likely the primary mechanism for kin recognition to avoid inbreeding within the colony,” said Heather Coffin, lead author of the paper. (more…)
Where do turtles belong on the evolutionary tree? For decades, the mystery has proven as tough to crack as the creatures’ shells. With their body armor and retractable heads, turtles are such unique creatures that scientists have found it difficult to classify the strange animals in terms of their origins and closest relatives.
“We know turtles evolved from a common ancestor along with birds, lizards and snakes about 300 million years ago, but who modern-day turtles are most closely related to is one of the biggest and most controversial questions in the field of systematics,” said Tyler Lyson, a Yale University graduate student who studies the evolutionary relationships between different animal groups.

One in 10 species could face extinction by the year 2100 if current climate change impacts continue.
This is the result of University of Exeter research, examining studies on the effects of recent climate change on plant and animal species and comparing this with predictions of future declines.
Published in leading journal Proceedings of the National Academy of Sciences, the study uses the well-established IUCN Red List for linking population declines to extinction risk. The research examines nearly 200 predictions of the future effects of climate change from studies conducted around the world, as well as 130 reports of changes which have already occurred. (more…)
SANTA FE, N.M.— Garbage mounds left by prehistoric humans might have driven the formation of many of the Florida Everglades’ tree islands, distinctive havens of exceptional ecological richness in the sprawling marsh that are today threatened by human development.
Tree islands are patches of relatively high and dry ground that dot the marshes of the Everglades. Typically a meter (3.3 feet) or so high, many of them are elevated enough to allow trees to grow. They provide a nesting site for alligators and a refuge for birds, panthers, and other wildlife. (more…)
*MU researchers find that man-made development affects bird flight patterns and populations*
COLUMBIA, Mo. – It may seem like birds have the freedom to fly wherever they like, but researchers at the University of Missouri have shown that what’s on the ground has a great effect on where a bird flies. This information could be used by foresters and urban planners to improve bird habitats that would help maintain strong bird populations.
