The relict population of Neotoma fl oridana occurring along the Niobrara River in north-central Nebraska was found to have a diet composed of 38 types of food items of which 37 types were plants. Unique features of the summer diet of this population were a higher than expected use of red cedar (Juniperus virginiana) and invertebrates as food items.
In this paper, three new Phyllocoptini eriophyoid mite species from Yunnan Province, China are described and illustrated: Proiectus rodgeseta sp. nov. on Pinus armandii Franch. (Pinaceae), Proiectus granularpro sp. nov. on Pinus tabuliformis Carr. (Pinaceae) and Phyllocoptrutajuniperiana sp. nov. on Juniperus chinensis Linn. (Cupressaceae). All are vagrants causing no apparent damage to their h...
To test the hypothesis that eastern red cedar (Juniperus virginiana L.) is allelopathic, seedling establishment of five herbaceous prairie species was evaluated by growing seeds in soil collected beneath and adjacent to a stand ofthis tree species. While four species showed no significant effect, the gennination of one species, finger coreopsis (Coreopsis pa/mata Nutt.), was significantly reduc...
مقدمه: تغذیه گیاه عامل مهمی در رشد و ترکیبات شیمیایی گیاهان است. کاربرد کودهای طبیعی می تواند عملکرد و شاخص های دارویی گیاهان را ارتقاء بخشد. هدف: در این تحقیق امکان جایگزینی کودهای شیمیایی با کودهای زیستی: نیتروکسین، بیوفسفر و بیوسولفور در تولید گیاه دارویی سرخارگل از طریق مقایسه عملکرد پیکر رویشی و ترکیبات فنلی گیاه در پاسخ به سطوح خالص و یا تلفیقی کودهای زیستی با اوره بررسی شد. روش بررسی: ای...
BACKGROUND Juniperus communis Linn. is an important plant in India traditional system of medicine which is widely used by different tribes in many countries. OBJECTIVE In the present study, the antioxidant, cytotoxic and hepatoprotective activities of Juniperus communis leaves were investigated against various models. MATERIALS AND METHODS ethanolic extract (70% v/v) of J. communis leaves w...
In arid ecosystems, abiotic processes facilitate the physical and chemical degradation of plant litter to the extent that decomposition models that use climatic and litter composition variables as surrogates for microbial activity are not predictive. The purpose of this study was to estimate the potential contribution of photodegradation to the decomposition of plant litters that varies in arch...
A bulk collection of terminal branchlets was made from J. pinchotii and subjected to drying at 42oC (24 hrs), then stored for up to 24 mos. at 22oC (room temperature, RT). The oils were distilled and analyzed from fresh, 0.5, 1, 2, 4, 8, 16, and 24 mos. storage at RT. The oil yields showed a slight decline initially, but remained fairly constant. Camphor, camphene hydrate and citronellal declin...
