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

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

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

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

At Camp Albion, Boulder County, Colorado, an unusual assemblage of ore and gangue minerals is found in a sheared and brecciated zone cutting the contact between pre-Cambrian gneiss and a composite Tertiary monzonite stock.Petrographic and chemical-mineralogic studies suggest that the ore was deposit

Otero County, situated on the High Plains of eastern Colorado, typifies many rural agricultural counties. This article surveys its history, demography, and social economy during the period from its formation in 1889 to 1987. It compares the county's demographic changes with those of the state and pr

As Colorado River Basin states prove unable to reach a consensus in reducing their water consumption, the U.S. Department of the Interior is investigating an option that defies the Law of the River.

Many thanks to Remi Bullock for that introduction and, more broadly, to the Potter

Durante el verano y otoño de 1967, se realizaron levantamientos magnéticos de intensidad vertical en dos áreas adyacentes al pozo Rocky Mountain Arsenal Num. 1, localizado al NE de la ciudad de Denver, Condado de Adams, en el Estado de Colorado. Se dio a estos levantamientos el nombre de Arca Manila

The Dunmore lode is localized along a persistent fissure zone over two miles long and averaging nearly 100 feet in width along the length of the Dunmore claim. The fault in which the lode is located offset the pre-Cambrian quartzite and slate walls about 4,500 feet prior to deposition of the overlyi

Ferberite, the chief tungsten mineral, occurs in (a), coarse textured, drusy veins; (b), stringers with chalcedony and cryptocrystalline quartz; and (c), breccia fragments. In (a), ferberite coats the walls, and scheelite is in the druses; in (b), ferberite likewise encrusts the walls and quartz cru

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

Abstract The Black Hollow field is located in Weld County, Colorado, on the W. flank of the Denver-Cheyenne Basin. The producing reservoir is the Lyons Sandstone of Permian age. Seismic work was begun in the area in 1944, following up gravity leads resulting from a gravity survey done in 1943. A min

The identities of avian nest predators remain unknown in many systems. The Mountain White-crowned Sparrow (Zonotrichia leucophrys oriantha) is a high-elevation ground-nesting passerine for which only 4 of 15 suspected nest predator species have been confirmed. In this short communication, we confirm

The delta of the Colorado River in Mexico historically contained 780,000 ha of riparian, marsh, and gallery forest habitat. Similar to other desert river deltas, such as the Nile and Indus, the lower delta of the Colorado River has been severely affected by the upstream diversion of water for human

Abstract Where climate is seasonal, such as in high‐altitude ecosystems, the occurrence and activity patterns of insect pollinators may vary with the varying occurrence of floral resources. This high turnover of species occurrence and interactions may lead to changes in the structure and properties
