abstract     the major constraints of agricultural production in the south western coastal areas of bangladesh are soil and water salinity of varying degrees, lack of fresh water for irrigation, slow soil drying pattern which are being augmented further due to climate change, requires suitable options of farming systems and component technologies. the major constraints and potentials of agricul...

the purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof nodushan, yazd. the plant species cover and the environmental variables were measured at 9 sites. soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. vegetation was classified using twowayindicator species analysis (twinspan). data was analyzed u...

Feeding farmed Artemia with yeast heat shock proteins is a novel way to protect them from stress conditions during the culture.  In this study, the effect of feeding with stressed new identified Saccharomyces cerevisiae strain YG3-1 yeasts (containing induced heat shock proteins) on the survival of Artemia in stress conditions, was evaluated. For this purpose, heat shock proteins 82 (Hsps 82) o...

This study evaluated the susceptibility of Penaeus vannamei, Kona stock-line, to infection by an isolate of Taura syndrome virus from Belize (TSV-BZ) under hyperthermic conditions (32 degrees C). Shrimp exposed to the reference Hawaii-94 isolate of TSV (TSV-HI) showed resistance to infection at 32 degrees C as demonstrated by the absence of mortality, histopathological lesions and decreased vir...
