Waste stabilization pond systems are widely used to treat animal wastes under highly variable hydraulic loading regimes. These systems have received limited research attention with regard to their hydrodynamic behaviour and the potential impact of shock hydraulic loading on their performance. In this study a two-stage dairy shed waste stabilisation pond system was topographically surveyed to de...

as the first case, a baby red eared slider turtle, trachemys scripta elegans, 1.77 inches long, with a 4 month history of anorexia and blind eyes was referred to the aquatic animal clinic, school of veterinary medicine, shiraz university, iran. the eyes of the pet were swollen and he was not active in swimming and feeling around. in the clinic, after stress treatment, he was kept in a clean aqu...

sewage stabilization pond is recommended as one of the economical methods for sewage treatment particularly in dry areas of the world and those places which are in shortage of water and income deficit, this method can be used for treatment of sewage in rural areas, small towns and even large cities. sewage stabilization pond system does not require technical equipment and specialists, and efflu...

Introduction of sahar in cage-cum-pond integration system of mixed-sex Nile tilapia was evaluated using 15 outdoor cemented ponds of 24 m2 (4.9m × 4.9m) size with 1.25 m water depth placing a cage of 1.2m× 1m × 1m size holding 1 m3 water at the center of each pond at Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, for 158 days. The experiment was conducted in a completely r...

The turtle shell is a wonderful example of a genuine morphological novelty, since it has no counterpart in any other extant vertebrate lineages. The evolutionary origin of the shell is a question that has fascinated evolutionary biologists for over two centuries and it still remains a mystery. One of the turtle innovations associated with the shell is the carapacial ridge (CR), a bulge that app...

Despite increased efforts from government agencies, scientists, and non-government organizations over the past few decades, anthropogenic sources of sea turtle mortality continue to threaten the survivorship of sea turtle species around the globe. More recent efforts to engage local people with community-based sea turtle conservation programs have been based primarily on economic incentives and...

The heat extraction from the lower convective zone or storage zone of salinity gradient solar pond with corrugated bottom is investigated with the aim of increasing the overall efficiency of collecting solar radiation, storing heat and delivering this heat to different applications. The energy balance equations for each zone have been used to develop the expression of temperature distribution i...

Urea is the major excretory end product of nitrogen metabolism in most chelonian reptiles. In the present study, we report the isolation of a 1632 base pair cDNA from turtle kidney with one open reading frame putatively encoding a 403-residue protein, the turtle urea transporter (turtle UT). The first cloned reptilian UT has high homology with UTs (facilitated urea transporters) cloned from ver...

40 With increasing atmospheric CO2 concentrations, the oceans are expected to increase in acidity during the next century. Increasing ocean acidity has been shown to negatively affect many marine ecosystems, particularly calcifying organisms. We investigated acidification effects on the turtle grass communities of Little Cayman Island, British West Indies (BWI). We hypothesized that acidified s...
