مدیریت در عرصه های منابع طبیعی تجدید شونده به ویژه پوشش گیاهی آن، بدون شناخت دقیق و جامع عناصر اصلی آن امکان پذیر نیست. طرح ملی آت اکولوژی گونه های مهم مرتعی با همین هدف در کل کشور به اجرا درآمده است. در مطالعه حاضر آت اکولوژی گونه salsola orientalis که نام جدید salsola rigida است در استان اصفهان و در منطقه موته بمدت سه سال از 1376 تا پایان 1378 مورد تحقیق قرار گرفت. بدین منظور مجموعه ای از عو...
Macroalgal blooms occur worldwide and have the potential to cause severe ecological and economic damage. Narragansett Bay, RI is a eutrophic system that experiences summer macroalgal blooms composed mostly of Ulva compressa and Ulva rigida, which have biphasic life cycles with separate haploid and diploid phases. In this study, we used flow cytometry to assess ploidy levels of U. compressa and ...
Parapiptadenia rigida is a tropical early secondary succession tree characteristic of the Tropical Atlantic Rainforest. This species is of great ecological importance in the recovery of degraded areas. In this study we investigated the variability and population genetic structure of eight populations of P. rigida. Five AFLP primer combinations were used in a sample of 159 individuals representi...
Salsola is one of the largest and most important genera in the family Chenopodiaceae. Salsola species are used for their anti-inflammatory, antinociceptive, anthelmintic and antipruritic effects and also as diuretic in traditional medicines worldwide. The aim of the present study is to assess the activity potential of the extracts, subextracts and isolated compounds from the aerial parts of and...
The byssus is the set of proteinaceous threads widely used by bivalves to attach themselves to the substrate. Previous researchers have focused on a single byssate family, the Mytilidae. However, the properties of byssal threads from species outside this family are of interest - first, because evolutionary patterns are only detectable if species from a range of taxa are examined, and second, be...
Ethanol whole plant extracts of three halophytic plants from Bahrain Sesuvium verrucosum, Salsola baryosma, Zygophyllum quatarense have been tested for their cytotoxic activity by the brine shrimp method. Only S. verrucosum showed a marked significant activity (LC(50) = 102.7 microg/mL)

The in vitro growth and differentiation of the alga Ulva rigida C. Agardh have been studied. Plants grown in enriched sea water (medium II and especially medium L) have a higher chlorophyll content and regularly release a large number of reproductive cells (in 10 days). This capability does not depend on the collecting season. It has been confirmed that axenic Viva cultures grown in solution de...
Burkholderia sp. strain UYPR1.413 is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from a root nodule of Parapiptadenia rigida collected at the Angico plantation, Mandiyu, Uruguay, in December 2006. A survey of symbionts of P. rigida in Uruguay demonstrated that this species is nodulated predominantly by Burkholderia microsymbionts. Moreover, Burkholderia sp. strain...
