in this study, macrobenthic bivalves were identified at 12 stations located in four regions (markazi, shahr no, khalasi, and gabrik creeks). the relationships between density of bivalves and non-biological factors were examined, as well. sampling of sediments was done seasonally from autumn 2009 to summer 2010, by 0.04 m2 van veen grab, in three stations including mouth, middle and end of each ...

Rotaviruses were concentrated from 8-liter samples of raw domestic sewage and sewage-polluted creek water by adsorption to and elution from positively charged microporous filters (Zeta Plus 60S), followed by ultracentrifugation of the filter eluates. Indirect immunofluorescence and direct immunoperoxidase methods allowed detection and enumeration of rotavirus in 6 (20.6%) of 29 sewage samples a...

We combined a conceptual rainfall-runoff model and input-output relationships of stable isotopes to understand ecohydrological influences on hydrological partitioning in snow-influenced northern catchments. Six sites in Sweden (Krycklan), Canada (Wolf Creek; Baker Creek; Dorset), Scotland (Girnock) and the USA (Dry Creek) span moisture and energy gradients found at high latitudes. A meta-analys...

Spatio–temporal variations in the distribution and community structure of the estuarine larval fishes on the west coast of Taiwan was examined in the estuaries of Shuangchi Creek (SC), Gongshytyan Creek (GST), Tatu Creek (TT) and Tongkang River (TK). Fish were collected by a net (mesh 0.8–1.8 mm) set against the flood tide at night during the newand full-moon periods from September 1997 through...

 Seasonal changes of the thyroid gland structure and hormones secretion was examined in yellowfin seabream (Acanthopagrus latus) in the northwest of Persian Gulf (Musa creek). Thyroid gland composed of follicles scattered around the ventral aorta, near the gills. Follicular cells varied according to secretion of the gland during warm and cold seasons. Thyroid hormones (Triidothyronine [...
