Bromus danthoniae Trin. is an annual grass species that is well adapted to harsh climates and could be considered as an important genetic resources for tolerance to environmental stresses such as salinity. In this study, 24 genotypes collected from Ilam, Kurdistan, Kermanshah (non-saline areas) and West Azerbaijan (saline area: shores of Uremia Salt Lake) provinces of Iran were investigated at ...
Lake Siombak is a tidal lake that an estuary around the covered with various mangrove trees. It interesting to study fish's spatial and temporal distribution as unique distinctive ecosystem. This research was conducted for year (from September 2018 August 2019). Fish sampling performed by installing gill nets (mesh size 1 inch) cast 0.5 inch). Gill were installed at high low tides during full m...
Background and Aim: In this research we isolated the bacterial species degrading polycyclic aromatic hydrocarbons (PAHs) and determined optimal salt concentration for PAH degradation.Materials and Methods: We used naphthalene and anthracene as the only sources of carbon for isolating PAH-degrading bacteria the main culture medium was ONR7a. The bacteria isolated by this method were used for the...
Urmia Lake is one of the largest hyper saline lakes in the world and largest inland lake in Iran which located in the north west of Iran, between the provinces of East Azerbaijan and West Azerbaijan. The lake basin is one of the most influential and valuable aquatic ecosystems in the country and registered as UNESCO Biosphere Reserve. In addition, it is very important in terms of water resource...
Eleven prairie saline (conductivity 1.8-58.8 mS cm-‘) lakes were examined over the 1994 growing season to determine what salinity-related factor or factors were responsible for controlling phytoplankton standing crops. The study lakes were characterized by high total P (0.15-24.2 mg liter-‘), total N (3.75-12.35 mg liter-‘), total Fe (552,800 p,g liter-‘), dissolved organic C (40-195 mg liter-l...
a r t i c l e i n f o Keywords: Lake Malawi Ostracoda Lake levels Climate change Ostracod species from at least seven genera were recovered from drill cores recently collected at Lake Malawi, a large (29,500 km 2) and deep (706 m) African rift valley lake located in the southern African tropics (9–14° S). Allocypria? and an unknown Cypridosine. Taphonomic variables such as the percentage of val...
Plants may induce small-scale heterogeneity in soil nutrients, forming fertile islands. However, this process may depend on plant spices, plant developmental stages and habitat conditions. Vegetation cover in arid and semi-arid regions is mostly in the form of plant patches and bare soil of inter-patch areas, this form of vegetation cover can be useful to study plants impact on soil to get appl...
Remote sensing is increasingly used in studies of periodic changes of land use and landsurface temperature (LST) calculations. In this paper, the effect of change in the area ofMaharlu Lake on climatic elements, land surface temperature and vegetation cover in theareas surrounding the lake were studied. To this end, the ETM + & TM sensor data ofLANDSAT satellite on May 22, 1987, May 17, 2000, M...
background: groundwater nitrate pollution is an important environmental problem in water resources management. in this regard, specific measures aiming at prevention of water pollution will be helpful to managers and decision-makers. identification of aquifers’ vulnerable areas and determination of groundwater protection zones using most widely used models, such as drastic and cd, are one of th...
