Many regions of southern California's coastal sage scrub (CSS) are rapidly declining as exotic annual plants replace native shrubs. During this conversion, the subsurface hydrology of the semiarid hillslopes that support CSS may be altered. This could chronically suppress the ability of native shrubland to revegetate the landscape since ecosystem processes of nutrient availability and of seedli...

We compared nutritional quality and morphology of 4 browse forages of black-tailed deer (Odocoileus hemionus columbianus) and Roosevelt elk (Cervus elaphus roosevelti) in clear-cuts and oldgrowth forests on the Olympic Peninsula, Washington. Browse in old-growth forests had a greater proportion of leaves, was more succulent, and had higher percent crude protein than browse in clear-cuts. There ...

There is considerable variability in salt tolerance amongst members of the Triticeae, with the tribe even containing a number of halophytes. This is a review of what is known of the differences in salt tolerance of selected species in this tribe of grasses, and the potential to use wild species to improve salt tolerance in wheat. Most investigators have concentrated on differences in ion accumu...

Nitrogen-fixing plants, by altering the availability of soil N, potentially facilitate plant invasion. Here we describe how herbivore-driven mortality of a native Nfixing shrub, bush lupine (Lupinus arboreus), increases soil N and light availability, which promotes invasion by introduced grasses to the detriment of a native plant community. Soils under live and dead lupine stands contained larg...

The effect of feeding freshly-cut common grasses on growth performance of Black Bengal goats during the pre-monsoon and pre-dry season was evaluated. Four castrated goats of 5-6 months age with a mean initial body weight were 11.17 and 10.23 kg for pre-monsoon and pre-dry season respectively, were used as experimental animal. Nutrient during the premonsoon season contained higher nitrogen (15.6...

warm-season bunch grass native to the eastern United States and is still often found east of Kansas and Oklahoma. This highly productive grass is best adapted to wet habitats; and remnant colonies are commonly found in flood plains and along stream banks. Eastern gamagrass is a relative of field corn (Zea mays) and is characterized by numerous short, well-developed rhizomes. Lower culm internod...
