Oxidative stress tolerance in intertidal red seaweed Hypnea musciformis (Wulfen) in relation to environmental components.
Oxidative stress parameters in relation to temperature and other factors have been analysed in Hypnea musciformis, the red seaweed from Anjuna beach, Goa, with an aim to understand its susceptibility to the changing seasons. The results indicate that elevated temperature, sunshine and dessication during peak summer in May enhanced the activity of lipid peroxide, hydrogen peroxide and antioxidan...
متن کاملEffects of Seawater Salinity and Temperature on Growth and Pigment Contents in Hypnea cervicornis J. Agardh (Gigartinales, Rhodophyta)
This study simulated outdoor environmental living conditions and observed the growth rates and changes of several photosynthetic pigments (Chl a, Car, PE, and PC) in Hypnea cervicornis J. Agardh (Gigartinales, Rhodophyta) by setting up different ranges of salinity (25, 30, 35, 40, 45, and 50) and temperature (15, 20, 25, and 30°C). At conditions of culture, the results are as follows. (1) Chang...
متن کاملمطالعه تنوع درون گونه ای در گونه های Hypnea (Rhodophyta, Gigartinales)
مطالعه حاضر به بررسی مورفومتری و تنوع ژنتیکی 24 جمعیت از Hypnea می‌پردازد. تجزیه و تحلیل‌های آماری نشان داد که صفاتی مانند روش پیشروی انشعابات در زیستگاه، اندازه و موقعیت تتراسپورانژها نقش مهمی در تنوع درون گونه ای داشته است. در هر دو تجزیه و تحلیل‌های مورفومتری و تنوع ژنتیکی، در گروه‌بندی جمعیت‌ها، گونه‌ها به خوبی از هم جدا شده‌اند اما جمعیت‌ها به خوبی از هم جدا نشده‌اند. تجزیه و تحلیل‌ها ...
متن کاملDifferences in physiological responses between winter and summer Gracilaria tenuistipitata (Gigartinales, Rhodophyta) to varying temperature
Gracilaria tenuistipitata var. liui Zhang et Xia, which is farmed in brackish water ponds of southern Taiwan as a major food of sea abalone, produces poor yields in winter. This study investigated the effects of year, location (pond), and season on the physiological responses of G. tenuistipitata to varying temperature. Neither year nor pond affected the physiological parameters. Season signifi...
متن کاملIn vitro exposure of Ulva lactuca Linnaeus (Chlorophyta) to gasoline - Biochemical and morphological alterations.
Refined fuels have considerable share of pollution of marine ecosystems. Gasoline is one of the most consumed fuel worldwide, but its effects on marine benthic primary producers are poorly investigated. In this study, Ulva lactuca was chosen as a biological model due to its cosmopolitan nature and tolerance to high levels and wide range of xenobiotics and our goal was to evaluate the effects of...
