Most believe the imperial woodpecker faded unseen into history in the late 20th century in the high mountains of Mexico. But now the largest woodpecker that ever lived can be seen once more in an 85-second flight that offers us a lesson its behavior, and ours.
Rangelands is a full-color publication of the Society for Range Management published six times per year. Each issue of Rangelands features scientific articles, book reviews, and society news. Additionally, readers may find youth, technology, and policy departments. The journal provides a forum for readers to get scientifically correct information in a user friendly, non-technical format. Rangelands is intended for a wide range of individuals, including educators, students, rangeland owners and managers, researchers, and policy leaders. The journal is available online at www.srmjournals.org. To learn more about the society, please visit www.rangelands.org.
DNA sequences for human and chimpanzees are nearly indentical, despite vast phenotypical differences between the two species. Georgia Tech researchers have determined that the insertion and deletion of large pieces of DNA near genes are highly variable between humans and chimpanzees and may account for these major differences.
Researchers in the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech have identified the first strains of hepatitis E virus from farmed rabbits in the United States. It is unknown whether the virus can spread from rabbits to humans.
In a new camera trap survey in the world’s most biologically diverse landscape, researchers for the Wildlife Conservation Society have identified more individual jaguars than ever before.
While European settlers were spreading across North America, the coyote, originally a creature of the American Midwest, was also expanding its territory. Changes in North American ecosystems have helped the coyote spread west to the Pacific, east to the Atlantic, north to Alaska, and south all the way to Panama. Following the coyote’s eastward expansion route, researchers have found evidence of hybridization with the endangered red wolf, and now, the Great Lakes wolf, which according to some biologists is a distinct species.
Preliminary results from a 2011 survey conducted by researchers at the Virginia Institute of Marine Science (VIMS) reveals a strong class of young-of-year striped bass will enter the adult population in 2012. That's good news for anglers and the Chesapeake Bay ecosystem.
Researchers at the University of Montreal have developed a computer programme that enables regulators to evaluate the ecological and economic tradeoffs between marine mammal conservation, whale watching and marine transportation activities in the Saint Lawrence Estuary.
Researchers with the Virginia Institute of Marine Science will embark on October 15 for a 3-and-a-half-week visit to sturgeon collaborators and collections at natural history museums in Russia, Romania; and France. The ultimate goal of the collaborative international study is to resolve the tangled classification of this ancient and threatened group of fishes in order to make more informed conservation decisions.
In the waters along Florida’s east and west coasts, Florida State University marine biologists are collecting new data on the once severely overfished Atlantic goliath grouper, a native species that is making a comeback in the southeastern United States after a 21-year moratorium on its capture while remaining critically endangered everywhere else in the world.
Actors Jack Black, Owen Wilson and Steve Martin go on a one-year search for birds in the upcoming comedy film, “The Big Year.” The movie, which debuts in the United States on Oct. 14, includes 18 sounds from the Cornell Lab of Ornithology’s Macaulay Library, the world’s largest collection of animal sounds.
A team of Russian veterinary colleagues and health experts from the Wildlife Conservation Society’s Bronx Zoo are collaborating to understand how distemper – a virus afflicting domestic dogs and many wildlife species – may be a growing threat to Siberian (Amur) tigers.
When a species recovers enough to be removed from the federal endangered species list, the public trust doctrine – the principle that government must conserve natural resources for the public good – should guide state management of wildlife, scientists say.
Researchers discover an unlikely trait shared between humans and song birds in the way that we sing.
The invasive sea squirt, Styela clava, has now been discovered along the Eastern Seaboard as far south as Bridgeport Harbor and poses a significant danger to Connecticut’s $30 million shellfish business, according to field research conducted by Carmela Cuomo, head of the marine biology program at the University of New Haven, and several of her students.
The Outing Club organizes an annual Peak Weekend, in which they try to place participants on all 46 "high peaks" of the Adirondack Mountains.
Two teams of Indiana State students spent their summer working in the southern Appalachian Mountains researching the federally endangered Indiana bat, the little-known eastern small-footed bat and acoustic activity of bats.
Fish in a cramped, barren space turn mean, a study from Case Western Reserve University has found. With nearly 183 million ornamental fishes in tanks across the U.S., that's a big deal, researcher says.
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 where their homes are and to determine if they are related to a potential mate.
Call a bird “birdbrained” and they may call “fowl.” Cornell University researchers have proven that the capacity for learning in birds is not linked to overall brain size, but to the relative size and proportion of their specific brain regions.
