The detailed distribution of Gammarus duebeni in freshwater habitats is discussed by Hynes (1954) and Sutcliffe (1967a). It occurs in a number of isolated coastal localities situated on the western sea-boards of Britain, including the Isle of Man, and on the Shetlands, the Faroes, Iceland, Norway and Brittany. In most of these localities the amphipod is restricted to only a few of the streams a...

We examined patterns of habitat function (plant species richness), productivity (plant aboveground biomass and total C), and nutrient stocks (N and P in aboveground plant biomass and soil) in tidal marshes of the Satilla, Altamaha, and Ogeechee Estuaries in Georgia, USA. We worked at two sites within each salinity zone (fresh, brackish, and saline) in each estuary, sampling a transect from the ...

Growth of American eels, Anguilla rostrata (Lesueur), sampled in saltwater bays and adjacent freshwater ponds in the southern Gulf of St. Lawrence, Canada, was estimated by otolith annulus back-calculation, and related to salinity of growth habitat as determined using otolith strontium:calcium ratios. Eels resident in salt water grew on average in length 2.2 times faster than freshwater residen...

In the present investigation a total of six parasite species, some eye-specific and others non-organ specific parasites were found in the eyes of 48 examined fish species, collected from fresh and brackish waters of Iran during 2004-2006. Ichthyophthirius multifiliis  was isolated from the external surface of the eyes of Oncorhynchus mykiss, Gyrodactylus stankovici from Cyprinus carpio and Lern...

The survival of 'atypical', cytochrome oxidase-negative Aeromonas salmonicida in microcosms containing sterilized water and sediment was assessed using the plate count method. The effect of sal~nity, temperature and presence of sediment was investigated on the survival of 2 strains isolated from ulcerated flounder Platjcl~thys flesus from the northern Baltic Sea. The strains survived for only a...

–The Late Triassic (Norian) phytosaurs Nicrosaurus kapffi and Mystriosuchus planirostris appear at about the same time in central Europe. Both have very distinctive snout shapes and are thought to occupy different ecological niches. The depositional environment and post-cranial morphology suggest a secondarily terrestrial lifestyle for Nicrosaurus. Some phytosaurs might have exploited coastal h...

Flat plate-type solar water distillation (FPSWD) is having importance for providing hot water and drinking water simultaneously to households in rural areas or small community/hotels. It utilizes solar radiation to heat the water, produce fresh water out of the saline or brackish water, and also produce hot water. The paper is focused on field performance of inclined FPSWD for domestic and comm...

this experiment was conducted to increase the resistance of tiger barb (capoeta tetrazona ) against environmental stress by feeding brackish water gammarus sp. powder as supplementary diet in three levels (25%, 50% and 75%) and three replicates pe group compared to control group for 60 days. fishes was fed with 4 diet treatment containea of: 100% artificial diet (control group), 25% brakish wat...
