Congenital stationary night-blindness associated with myopia may be transmitted by two types of inheritance: X-linked recessive (Worth, 1906; Nettleship, 1909 and 1912; Kleiner, 1923) and autosomal recessive (Nettleship, 1912; Vogt, 1923; Gassler, 1925; Akiya, 1935; Merin et al, 1970). There are only a few reports of either variety. The present paper describes a family where 3 sibs are affected...
به منظور شناسایی پارازیتوییدهای سپردار سفید کیوی، (Pseudaulacaspis pentagona (Targioni-Tozzetti در استان مازندران، نمونه برداری از درختان کیوی منطقه قائمشهر در سال های 95-1393 انجام شد. در بین نمونههای جمعآوری شده، زنبور پارازیتوئید (Aphytis chrysomphali (Mercet, 1912)(Hymenoptera: Aphelinidae شناسایی شد. این گونه برای اولین بار روی سپردار سفید کیوی از ایران گزارش می شود.
Observations of ctenophore species were made in the Gulf of Trieste between 2003 and 2006. We examined native ctenophore species with special attention to representatives of the orders Lobata and Beroida, and we recorded among them two non-native ctenophores: Mnemiopsis leidyi A. Agassiz 1865 and Beroe ovata sensu Mayer, 1912. The validity of the Mediterranean species Beroe ovata is discussed. ...
