Abstract Maternal investment in mammals may take many forms, including spatial relocation of offspring. Litter relocation behavior, in which a female moves her litter to a new location, has been reported for several species of carnivores and rodents but has received little study. We describe litter

In 2012 the Marmot Library Network implemented the Douglas County Library Model of ebook collection and circulation. By 2014 Marmot had loaded 838 ebooks purchased direct from publishers and independent authors to an Adobe Content Server, and made them available in an open source discovery layer bas

Recent work in central Utah has outlined the broader features of the area's thrust geometry. Although individual interpretations differ, most models indicate the region is similar to better understood segments of the Cordilleran thrust belt. Poor and limited seismic data and the paucity of drill-hol

Abstract. A declining spring snowpack is expected to have widespread effects on montane and subalpine forests in western North America and across the globe. The way that tree water demands respond to this change will have important impacts on forest health and downstream water subsidies. Here, we pr

Abstract A new species of homolid crab, Zygastrocarcinus tricki sp. nov., is reported from the Late Cretaceous (middle Campanian, Baculites scotti Zone) of the Pierre Shale Formation (Baculite Mesa, Pueblo County, Colorado). This nearly complete homolid, hereto described is the sixth species assigne

Abstract. Harry Gunnison Brown's fifty plus years of active advocacy of land value taxation are reviewed in the light of two recent articles. One indicates a waning interest and even understanding of Brown's chosen cause while the other demonstrates quite the opposite: the persistence and relevance

Hunter harvest is a potential factor contributing to population declines of sage-grouse (Centrocercus spp.). As a result, wildlife agencies throughout western North America have set increasingly more conservative harvest regulations over the past 25 years to reduce or eliminate hunter success and co

The Uncompahgre Uplift within the Colorado Plateau contains several salt anticline valleys. The Moab Valley is situated within one of these valleys which formed as the underlying salt member of the Paradox Formation migrated. As the unit migrated, the resulting collapse of the valley left behind sur

THE Conservation Reserve Program (CRP) and conservation compliance provisions of the 1985 Food Security Act have had a dramatic impact in Colorado. As of May 1989, landowners in the state had enrolled more than 1.8 million acres in the CRP. Baca County, in southeastern Colorado, has the greatest num

Abstract Mountainous headwater streams are sustained by both snowmelt‐driven streamflow and groundwater discharge in the Upper Colorado River Basin. However, predicting headwater stream discharge magnitude and peak flow timing is challenging in mountainous terrains, where snowmelt rates vary with ve

In the course of nesting microclimatic studies of the Broad-tailed Hummingbird (Selusphorus platycercus), I observed three cases of intra-or interspecific piracy of nesting materials. These observations were made in the vicinity of the Rocky Mountain Biological Laboratory, Gothic, Gunnison County, C
