the role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولRemnant and Restored Prairie Response to Fire, Fertilization, and Atrazine
The effect of spring burning, fertilization, and atrazine on herbage yield of warmand cool-season grasses, flowering stalk density, and seed yield of selected warm-season grasses was determined on a remnant prairie and a restored prairie located near Lincoln and Center, Nebraska, respectively. Sites were burned in mid-April 1987 and followed by application of fertilizer (112 kg N/ha at the remn...
متن کاملFire Regimes and Avian Responses in the Central Tallgrass Prairie
Grasslands make up the largest vegetative province in North America, and one that has been signifi cantly altered over the past two centuries. The tallgrass prairie of the eastern Great Plains and Midwest has declined to a greater extent than any other ecosystem, primarily due to plowing for cereal grain production. Grassland bird populations have declined at a greater rate and over a wider are...
متن کاملPrairies and Pastures of the Dissected Loess Plains of Central Nebraska
INTRODUCTION Lvni-north of the great southward bend o[ the Platte River in central Nebraska but southeast of the sandhills, there are several thousand square miles of rugged uplands known as loess bluffs. They are quite unlike the sandhills with their typical cover, largely of postelimax tall grasses. They also differ widely from the Nebraska plain eastward and south-eastward where mid-grass or...
متن کاملBiomass-diversity responses and spatial dependencies in disturbed tallgrass prairies.
Monotonic, hump-shaped and zero-correlation productivity-diversity relationships have been found to date in many ecosystems. This diversity of responses has puzzled ecologists in their search for general principles on ecosystem functioning. Some state that the scale of observation is crucial in defining this relationship. We have developed a spatial model of tallgrass prairies where biomass and...
