Lake Sarez, which is located in the Pamir Mountains in Tajikistan, was created in 1911. A massive landslide, triggered by an earthquake, blocked the Murgab River valley, creating a natural dam, which was called Usoi. In 1999, the International Decade for Natural Disaster Reduction Secretariat led a mission to assess the risk and impacts in the Pamir Mountains of Tajikistan including this...

I am pleased to have had the opportunity to revise the first version of this set of course notes for the stream temperature models. In some ways, there have been many changes and in some ways the notes have stayed much the same. Generally, I was satisfied that the notes were both comprehensive and fairly easy to read. The exercises using SSTEMP have been upgraded to reflect advances in...

Executive Summary Cassin’s Sparrow (Aimophila cassinii) is a grassland species endemic to the southwestern U.S. and northern Mexico. Its behavior and ecology have been shaped by these arid ecosystems and the health of its populations is dependent on the availability of grasslands that contain a shrub component. Populations of many grassland birds have experienced dramatic declines due to...

Here, you will find a series of questions and answers resulting from many years of technical assistance with SNTEMP and SSTEMP. These (in)frequently asked questions are presented here so that you may get a feel for the range of questions posed, learn from the questions and their 'answers,' and share in the discussions if you wish. I certainly didn't answer all the questions, nor do I...

Ecological Studies of the Pryor Mountain Wild Horse Range, 1992-1997 provides a synthesis of key findings of landscape-scale, interdisciplinary studies of the effects of wild horses and native ungulates on a rugged, mountain ecosystem. This is perhaps the most comprehensive study of a wild horse herd conducted. This was a complex study and one involving a truly interagency approach. Six

Using the example of a reintroduced bighorn sheep population in Badlands National Park, South Dakota we demonstrate the usefulness of neutrality tests and demographic data for detecting a severe genetic bottleneck (Ne 10). From demographic data the effective population size of the founding population at Badlands was estimated to be six, and a heterozygosity excess test revealed evidence...

We monitored movements of small mammals resident on floodplains susceptible to spring floods to assess whether and how these animals respond to habitat inundation. The 2 floodplains were associated with 6th order river segments in a semiarid landscape; each was predictably inundated each year as snowmelt progressed in headwater areas of the Rocky Mountains. Data from live trapping...
