Long-range power-law correlations have been reported recently for DNA sequences containing noncoding regions. We address the question of whether such correlations may be a trivial consequence of the known mosaic structure ("patchiness") of DNA. We analyze two classes of controls consisting of patchy nucleotide sequences generated by different algorithms--one without and one with long-range po...
in this study, the spatial distribution of overwintered adults of sunn pest, eurygaster integriceps puton, was investigated by using dispersion parameters and indices, mathematical distribution, and regression techniques in rainfed wheat fields by sample size of 1 m2 in 2009 and 2010. the dispersion parameters including: mean-variance test and clumping parameter () showed that the overwintered ...
طی نمونه‌برداری‌هایی که در سال زراعی 90-1389 از شته‌های Rhopalosiphum maidis F. و Schizaphis graminum R. در مزارع گندم منطقه باجگاه، استان فارس، انجام شد، پراکنش فضایی و مدل‌های نمونه‌گیری دنباله‌ای با دقت ثابت مورد مطالعه قرار گرفت. برای این منظور دو مزرعه دو هکتاری انتخاب و به‌صورت هفتگی نمونه‌برداری انجام شد. در هر تاریخ تعداد 200 بوته گندم به‌طور تصادفی انتخاب و تعداد شته‌های آن‌ها شمارش ش...
Crown imperial scattered according to soil structure and organic matter in Zagros regions in Ilam. This plant has been performed an important role in the beautification of environment, tourist attraction and providing of plant essential oils which are used for the production of medicines. The current research was carried out to evaluation spatial distribution pattern of Fritillaria imperialis i...
• Relations of Lloyd's I p macrobenthic patchiness studied in 6 types seagrass. Interspecific closely correlated with unoccupancy. Less so abundance, and not mean crowding, c. correlates the expression ' a .unoccupancy + (1? ) c where > 0.8. Patchiness-unoccupancy relationship unaffected by assemblage composition. The macroecological abundance-occupancy is well known; potential one either or bo...
Forest–savanna mosaics exist across all major tropical regions. Yet, the influence of environmental factors on distribution these is not well explored, limiting our understanding constraints savannas especially in Southeast Asia, where most mosaics. Despite clear structural and functional characteristics indicative savannas, SE Asian continue to be classified as forest. This designation problem...
