In this context, the creation in the year 2002 of a Natural Park, has positively released the pressure over this territory but, at the same time, h...
rangelands are among the natural resources which have a considerable effect on environment and man’s life. iranian rangelands mostly have poor condition and exhausted by intensive over grazing, should be utilized according to their ecological capability and land suitability. the main objective of this study is to evaluate ecological capability and land suitability of gheshlagh dam’s watershed a...
There are some barriers for rangers to take part in range plan projects andevaluation. Their participation is very useful for range managers to plan and provide solutionsfor solving problems. This study aims at comparing barriers of participating from rangers andexperts point of view in Lar moor rangelands, Tehran, Iran. In this research, data werecollected based on documentation-library and fi...
In order to investigate the effects of range management plans on species diversity, richness and evenness in Semirum rangelands, 52 sites (28 with treated plan and 24 without treated plan) were selected. The non-parametric indices for species richness (Margalof, Menhinick, Jacknife and counting method) and species diversity (Simpson, Camargo, Smith and Wilson and modified Nee) were compared in ...
چکیده: برش مورد مطالعه در 15 کیلومتری جاده ایلام به سمت مهران در منطقه ای تحت عنوان تنگ گراب قرار دارد. سازند گورپی متشکل از سنگهای نرم و تیره رنگ و لیتولوژی نرم بر روی سازند ایلام با سنگهای آهکی سخت و به رنگ سفید و نخودی قرار دارد. در این مطالعه تعداد 51 گونه متعلق به 23 جنس از فرامینیفرهای پلانکتونیک شناسایی و محدوده ی حضور آنها در برش مورد مطالعه تعیین شد. بر این اساس این سازند به 12 بایوزو...
Rangeland management projects considered to be a management tools to increase the quantity and quality of the rangelands. Persomably, It could work more efficintley in areas where the grazing pressure is high and consequently their condition and trend are regressive. In this study, production, range condition and range trend were examined before and after the implementation of the range managem...
بر اساس پخش و پراکندگی چینه شناسی روزنبران پلانکتونیک شناسایی شده از برش مورد پژوهش 9 بیوزون شناسایی و معرفی شد که منطبق با بایوزون های استاندارد جهانی در قلمرو تتیس بوده و به ترتیب ازپایین به بالا شامل : بیوزون 1)dicarinella concavata interval zone (سانتونین پسین) بیوزون 2) dicarinella asymetrica total range zone ( کامپانین میانی) بیوزون 3) globotruncanita elevata interval zone ( کامپانین پ...
We present a long range planning (LRP) system, the Spike Plan Window Scheduler, which has been in use for observations on the Hubble Space Telescope (HST) for the past four years and which is being adapted for the Space Infrared Telescope Facility (SIRTF) and Next Generation Space Telescope (NGST) orbiting astronomical observatories. Due to the relatively underconstrained nature of this domain,...
