KEPADATAN DAN POLA DISTRIBUSI SACCOSTREA CUCULLATA DI PERAIRAN TELUK KENDARI

Thymineless death in polA+ and polA- strains of Escherichia coli.

The extreme sensitivity of polA(-) cells to thymineless death is due, primarily, to the absence of an extended lag prior to the commencement of death. Once thymineless death has commenced, the rate in polA(-) cells is only slightly faster than in polA(+) cells.

مقایسه بافتی ساختار روپوش در دوکفه‌ای مرواریدساز Pinctada radiata و دوکفه‌ای خوراکی Saccostrea cucullata

بافت روپوش دوکفه­ای­ها در شکل­گیری پوسته و مروارید نقش دارد. مطالعه حاضر به بررسی و مقایسه ساختار بافتی لبه روپوش در بین گونه­های مرواریدساز Pinctada radiata و خوراکی Saccostrea cucullata پرداخته است. این مطالعه، اولین پژوهش در زمینه مقایسه بافتی روپوش در بین دوکفه­ای­های مرواریدساز و غیرمرواریدساز خلیج فارس است. برای مطالعه لبه روپوش، قسمت قدامی، خلفی و مرکز لبه روپوش هر کفه جدا شد و مقاطع باف...

Biomonitoring Total Mercury in the Persian Gulf Using the Rock Oyster (Saccostrea cucullata)

This study is an attempt to evaluate the biomonitoring capabilities of rock oyster, Saccostrea cucullata, for mercury (Hg) pollution. The oyster and sediment samples were collected from 10 rocky habitats of Qeshm and Hormoz Islands in the Persian Gulf. The concentration of mercury in the shell and soft tissues of the oysters and sediments were analyzed using an advanced mercury analyzer. Biot...

بررسی مولکولی جمعیت صدف های خوراکی Saccostrea cucullata در سواحل شمالی خلیج فارس و دریای عمان

Journal of Marine Biology and Aquaculture

Along the Indian coast, oysters were identified and studied since the beginning of the 20th century. One of the first records on the taxonomy of Indian oysters is by Hornell (1910) [2]. Since then a series of reports on the taxonomy of Indian oyster were made[1,3,4-9]. Originally the Indian oysters were referred to under the genus Ostrea but was later included under the genus Crassostrea. Anoth...
