The natural abundance of stable carbon isotope values (δ13C) of organic matter of marine macroalgae collected from Taiwan and its offshore islands (Penghu Islands) were analyzed in this study. These values ranged from -10.5 to -29.5‰. The highest δ13C value came from green algae (-10.5‰), Ulva pertusa while most algae exhibited values in the -14 to -19‰ range. On average, the δ13C values of red...
تالاب و شبه جزیره میانکاله یکی از ذخایر اصلی زیست کره یونسکو در ایران و خاورمیانه است. تنوع فیتوپلانکتونی تالاب میانکاله از مهرماه 88 الی شهریور 89 بررسی شده است. بخشی از کار توسط رمضان نژاد قادی انجام گرفته و این دومین مطالعه فلورستیک جلبک در تالاب میانکاله ایران است. پنج گروه اصلی جلبکی به نام های باسیلاریوفیتا، سیانوباکتری ها، کلروفیتا، اوگلنوفیتا و گزانتوفیتا گزارش شده است. 95 گونه و واریته...
many studies on cold environments have been developed over the past two decades. highmountain freshwater presents high variability of nutrients and chemico-physical parameters, showing variations of ph, oxygen concentration, metals and temperature throughout the year. national park of sierra nevada (granada, spain) (37°032 n 03°182 w), has almost 40 lakes that are reported to be both endemic an...
in the present study the freshwater algae of siahdarvishan river were sampled on a montly basis from december 2007 through november 2008. three sampling stations (gaght roudkhan , shahkezr dame and talab laleh ) were chosen in the river. some physical and chemical parameters (water temperature , total hardness , nitrate , nitrite, phosphate and ph) of water samples were measured. a total of 84 ...

In this study, effects of pH and salinity on growth and bloom of Dunaliella sp. algae were investigated. The algae were reared in different pH (6.0, 6.8, 7.0, 7.3, 7.6, 8.0, 8.6, 9.0, 9.7 and 11.0) and salinities (20.0, 31.6, 50.1, 79.4, 117.1, 125.9 and 200.0 ppt) at Inland Aquaculture Research Institute Phycolab during 2011. After 96 h, the algae reared in 50ppt salinity and below that had ne...

Objective(s): Diabetes is a metabolic syndrome which is associated with the worldwide major public health problems. There are many natural compounds from the sea-market, as a valuable aquatic source, along with the variety of health and therapeutic benefits. In the present research, with respect to the traditional and ethnic uses of Sargassum oligocystum algae for healing of some diseases which...
Background: Marine algae, especially brown species, produce a wide range of metabolites with various biological activities. Objective: Since marine algae are rich source of dietary fibers, minerals, proteins, vitamins and phenolic components with antioxidant effect, in addition to the rule of oxidative stress in pathogenesis of chronic diseases, the aim of this study was to investigate possib...
