When Charles Darwin visited the Falkland Islands during the voyage of the Beagle in 1835, he saw a wolf-like species, wrote about it in his diaries and correctly commented that it was being hunted in ...
Life Sciences |A large and unexpected one, say wildlife biologists from Michigan Technological University. Joseph Bump, Rolf Peterson and John Vucetich report in the November 2009 issue of the journal Ecology that t...
Ecology, The Environment and Conservation |Wolves (Canis lupus) have been pursued by humans for centuries due to their supposed "addiction" to livestock. However, the study by Isabel Barja, sole author and researcher at the Universid...
Ecology, The Environment and Conservation |In “Canine and Feline Behavior and Training: A Complete Guide to Understanding Our Two Best Friends,” author Linda P. Case answers these questions and explains the divergent evolutionary paths of dogs...
Life Sciences |"For the first time in world history it is possible to provide a detailed picture of the dog, with its birthplace, point in time, and how many wolves were tamed," says Peter Savolainen, a bi...
Life Sciences |Variants in just three genes acting in different combinations account for the wide range of coat textures seen in dogs — from the poodle's tight curls to the beagle's stick-straight fur. A t...
Life Sciences |That means that village dogs from most African regions are genetically distinct from non-native breeds and mixed-breed dogs. They also are more genetically diverse because they have not been subjected...
Life Sciences |A series of tests, described in BioMed Central's open access journal Behavioral and Brain Functions, should caution researchers against making simple generalizations about the effects of domestic...
Life Sciences |The proposal is modeled after research done in the United States, at Yellowstone National Park and elsewhere, which has demonstrated that the absence of large predators such as wolves and cougars has ...
Ecology, The Environment and Conservation |A single evolutionary event appears to explain the short, curved legs that characterize all of today's dachshunds, corgis, basset hounds and at least 16 other breeds of dogs, a team led by the Na...
Life Sciences |But domestic dogs bark more than other animals for reasons related to their 10,000-year history of hanging around human food refuse dumps. Biologically speaking, many animals besides dogs bark...
Life Sciences |The wide-ranging list of endangered and threatened species includes such well known wildlife as snow leopards, wolves, and brown bears, but also lesser-known species such as the paghman salamander, go...
Ecology, The Environment and Conservation |Most such studies ignore differences between populations within a species and the interactions between species, in the interest of simplicity. An article in the June issue of BioScience, by Eric Post ...
Life Sciences |During a seminar at another institution several years ago, University of Chicago paleontologist David Jablonski fielded a hostile question: Why bother classifying organisms according to their physical...
Studies and Analyses |A biochemical analysis of a rare Clovis-era stone tool cache recently unearthed in the city limits of Boulder, Colo., indicates some of the implements were used to butcher ice-age camels and horses th...
