Summer low-flow behavior in the semi-arid areas of the Pacific Northwest was studied. Long-term data from thirty-eight streams/rivers and thirty-six precipitation stations was exploited. The study area was divided into five zones based on annual average precipitation. Trends and patterns
in summer low-flows and precipitation were identified. Different zones showed...
Five sympatric species of desert lizards (leopard lizards (Garnbelia wizlizeni), sagebrush lizards (Sceloporus graciosus), side-blotched. lizards (Uta stansburiana), desert horned lizards
(Phrynosoma platyrhinos), and Western whiptails (Cnemidophorus tigris)) were studied in June and July of 1978 and 1979 in northern Nevada on the Charles Sheldon National Wildlife Refuge. Lizard

Proper irrigation, despite being one of the most important factors in maintaining a healthy lawn, is the most often overlooked variable in lawn care. This publication describes common turfgrass species, soil water holding capacity, irrigation scheduling, and management practices to optimize irrigation efficiency.
A sequence of glaciation based on relative dating parameters was established
in each of nine mountain ranges located along a northwest to southeast transect
through the northern Great Basin. Each sequence consists of two or three drift units.
Degree of weathering suggests that the younger drift unit in a two-fold...
Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...
A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...
