Mammalian herbivores, particularly dietary specialists must have an efficient means to metabolize the high doses of plant secondary compounds they consume. We found previously that Neotoma stephensi, a juniper specialist, upregulated catechol-O-methyl transferase (COMT) mRNA almost seven fold in response to an ecologically relevant diet (70% juniper). To further investigate the relevance of thi...

Determination of suitable species is the most important factor in success of forestation in unfavorable conditions. One of the least costly and the shortest ways for introduction of adaptable species in an area is recognition of the plants that grow naturally. The objective in this study was to find out the effects of protection and water spreading operations on the quantitative improvement of ...

Western juniper (Juniperus occidentalis subsp. occidentalis) range expansion into sagebrush steppe ecosystems has affected both native wildlife and economic livelihoods across western North America. The potential listing of the greater sage-grouse (Centrocercus urophasianus) under the U.S. Endangered Species Act has spurred a decade of juniper removal efforts, yet limited research has evaluated...

Effects of replacing cottonseed hulls with dry redberry juniper leaves on performance and serum NEFA, urea N, and IGF-1 were investigated in Rambouillet lambs (n = 24, initial BW = 28.6 +/- 4.94 kg). In a study with 2 feeding periods (period 1 = 65% concentrate ration, 28 d; period 2 = 85% concentrate ration, 49 d), lambs were individually fed ad libitum treatment diets containing cottonseed hu...

The acaricidal effect of eleven essential oils (Sweet basil, Common juniper, Atlas cedar, Coriander, Blue gum, European silver fir, Common lavender, Lemon, Peppermint, Scots pine, Summer savory) against poultry red mite Dermanyssus gallinae was tested in vitro using the direct contact method, at three different doses: 0.2 mg/cm2, 0.4 mg/cm2 and 0.6 mg/cm2. The results of the study revealed that...

Iran has high vegetation diversity due to different climates and ecological conditions. Golestan province is one of the most diverse vegetation provinces in the country. Among the plant species of this province, the Juniper genus, with the presence of 6 native species, is one of the few coniferous species which is an important part of the under story vegetation flora of the area. Chahar Bagh Ju...

To isolate potential insect biocontrol agents, entomogenous nematodes were surveyed in Tennessee plant nurseries in 1991. Soil samples from 113 nursery sites were baited with greater wax moth (Galleria mellonella) larvae, house cricket (Acheta domesticus) adults, lesser mealworm (Alphitobius diaperings) adults, and house fly (Musca domestica) larvae. Heterorhabditis bacteriophora and Steinernem...
