Bison conservation initiative: Bison conservation genetics workshop: Report and recommendations Bison conservation initiative: Bison conservation genetics workshop: Report and recommendations
One of the first outcomes of the Department of the Interior (DOI) Bison Conservation Initiative was the Bison Conservation Genetics Workshop held in Nebraska in September 2008. The workshop brought together scientists from government agencies and non-governmental organizations with professional population geneticists to develop guidance for the genetic management of the federal bison...

Bringing wisents back to the Caucasus Mountains: 70 years of a grand mission Bringing wisents back to the Caucasus Mountains: 70 years of a grand mission
We describe the history of mountain wisent restoration in the north-west Caucasus region. We review information on wisent during the 18th and 19th centuries, contemporary regional development and reasons for wisent extirpation. We emphasize the key role of the Kuban Hunting Reserve as a main factor in preserving wisent in this region between 1888 and 1909. The article provides...

Survey of ungulate abundance on Santa Rosa Island, Channel Islands National Park, California, March 2009 Survey of ungulate abundance on Santa Rosa Island, Channel Islands National Park, California, March 2009
Reliable estimates of elk (Cervus elaphus) and deer (Odocoileus hemionus) abundance on Santa Rosa Island, Channel Islands National Park, California, are required to assess the success of management actions directed at these species. We conducted a double-observer aerial survey of elk on a large portion of Santa Rosa Island on March 19, 2009. All four persons on the helicopter were...

Historic distribution and challenges to bison recovery in the northern Chihuahuan Desert Historic distribution and challenges to bison recovery in the northern Chihuahuan Desert
Ecologists and conservationists have long assumed that large grazers, including bison (Bison bison), did not occur in post-Pleistocene southwestern North America. This perception has been influential in framing the debate over conservation and land use in the northern Chihuahuan Desert. The lack of an evolutionary history of large grazers is being used to challenge the validity of...

Second chance for the plains bison Second chance for the plains bison
Before European settlement the plains bison (Bison bison bison) numbered in the tens of millions across most of the temperate region of North America. Within the span of a few decades during the mid- to late-1800s its numbers were reduced by hunting and other factors to a few hundred. The plight of the plains bison led to one of the first major movements in North America to save an...

A simple solar radiation index for wildlife habitat studies A simple solar radiation index for wildlife habitat studies
Solar radiation is a potentially important covariate in many wildlife habitat studies, but it is typically addressed only indirectly, using problematic surrogates like aspect or hillshade. We devised a simple solar radiation index (SRI) that combines readily available information about aspect, slope, and latitude. Our SRI is proportional to the amount of extraterrestrial solar radiation
