The mining lease area of Surka [District Bhavnagar, Gujarat (India)] is located within 6-12 km horizontal distance of sea shore of Gulf of Cambay. Whenever, there will be onset of lignite extraction, there will be always a threat of sea water intrusion into the mining lease area due to its close proximity to seashore. This article describes the prediction of sea water intrusion into the lease a...

Secondarily marine vertebrates are thought to live independently of fresh water. Here, we demonstrate a paradigm shift for the widely distributed pelagic sea snake, Hydrophis (Pelamis) platurus, which dehydrates at sea and spends a significant part of its life in a dehydrated state corresponding to seasonal drought. Snakes that are captured following prolonged periods without rainfall have lowe...

STRONG evidence has been brought forward (Kitching, 1934, 1936 a) to show that in euryhaline marine peritrich ciliates the contractile vacuole prevents excessive swelling of the body when the organism is placed in dilute sea water. From this it has been inferred (Kitching, 1936 a, p. 24; and 1937) that in fresh-water Protozoa the contractile vacuole normally controls the body volume. In order t...

the silversides or sand smelts are found in coastal areas of temperate to tropical seas and in fresh water. there are about 14 genera and 68 species with only one native species in the caspian sea basin, atherina caspia . in this review, the systematics, morphology, distribution, biology, economic importance and conservation of the caspian silverside of iran are described, the species is illust...

The present study deals with biology, ecology and population dynamics of freshwater turtle Kachuga tentoria and its role as water purifier. The study area Panchnada is the site, where five important national rivers meet together and is preserving an appreciable population of nine species of fresh water turtles. Kachuga tentoria was located at all the sampling stations surveyed by the authors, a...

[1] Oxygen isotopic records of meltwater outflow and records of sea level change do not support the idea that fresh waters derived solely from the melting of Northern Hemisphere ice sheets was likely to have stabilized the upper layers of the North Atlantic Ocean and prevented deep convection during the Younger Dryas. Yet there are paleoceanographic indicators that point to a pause in the forma...

this study was carried out to investigate the occurrence of potentially pathogenic species of vibrio in sea water and estuarine environments of the caspian sea in the golestan province of iran. a total of 127 water samples from coastal waters as well as from river and estuaries were collected and analyzed by culture, during april and september 2001. following prompt centrifugation, the resuspen...

BACKGROUND Criminal offenders have a fundamental goal not to leave any traces at the crime scene. Some may suppose that items recovered underwater will have no forensic value, therefore, they try to destroy the traces by throwing items in water. These traces are subjected to the destructive environmental effects. This can represent a challenge for forensic experts investigating fingerprints. ...

It might be useful to start by stating arguments for the positive image of, or even prejudice about, Croatia as a country with some key and untapped advantages in comparison with other countries. Can we consider as founded the claims that this country has a preserved and relatively clean environment – air, land, water, soil, flora and fauna – an advantageous geo-strategic location and creative,...

Azolla nilotica does not occur in Egypt today, reaching as far north as central Sudan. Its spores have been recorded in sediment cores from the Nile Delta near Manzala Lake up to ca. 550 AD. As part of the CASSARINA Project on recent changes in ecosystems of North African lakes, short sediment cores, covering up to the last two centuries, were taken from the open water of the large Delta lagoon...
