Ecological effects of ranching: A six-point critique Ecological effects of ranching: A six-point critique

Ranching is the dominant land use in much of the American West. Although a copious literature has examined the effects of various grazing practices on native ecosystems, we present here the idea that ranching has important impacts on the land independent of those caused by grazing itself. If biological conservation is to be successful on the western grasslands and shrublands, ranchers...

Differences in native soil ecology associated with invasion of the exotic annual chenopod, Halgeton glomeratus Differences in native soil ecology associated with invasion of the exotic annual chenopod, Halgeton glomeratus

Various biotic and abiotic components of soil ecology differed significantly across an area whereHalogeton glomeratus is invading a native winterfat, [ Krascheninnikovia (= Ceratoides) lanata] community. Nutrient levels were significantly different among the native, ecotone, and exotic-derived soils. NO3, P, K, and Na all increased as the cover of halogeton increased. Only Ca was highest...

Identification of a genetic marker that discriminates ocean-type and stream-type chinook salmon in the Columbia River basin Identification of a genetic marker that discriminates ocean-type and stream-type chinook salmon in the Columbia River basin

A marker based on randomly amplified polymorphic DNA (RAPD), OT-38, was discovered that nonlethally discriminates between stream-type and ocean-type populations of chinook salmon Oncorhynchus tshawytscha in the Columbia River basin, including the threatened fall-run (ocean-type) and spring-run (stream-type) Snake River populations. This marker was developed by amplifying chinook salmon...
