coastal monitoring programs are valuable tools for assessing the current state of coastal environments, for determining spatial and temporal trends in pollution and identifying potential sources of contaminants. monitoring often involves organisms from different environments, such as estuarine and intertidal zones, where conditions (e.g. salinity, temperature) fluctuate. Biomarkers “report” on ...

Shark nurseries are susceptible to environmental fluctuations in salinity because of their shallow, coastal nature; however, the physiological impacts on resident elasmobranchs are largely unknown. Gummy sharks (Mustelus antarcticus) and school sharks (Galeorhinus galeus) use the same Tasmanian estuary as a nursery ground; however, each species has distinct distribution patterns that are coinci...

We present a seasonal and baseline survey of selected physicochemical parameters in epipelagic samples from Qua Iboe (QIB) and Cross River (CRV) estuaries in Niger Delta region of Nigeria. The parameters analysed were temperature, pH, salinity, turbidity, total suspended solids (TSS), dissolved oxygen (DO), biochemical oxygen demand (BOD), total organic carbon (TOC), total nitrogen, available p...

seed germination is a crucial stage in the plant life cycle and salt tolerance during germination stage is vital for the establishment of plants in saline soils. in order to evaluation of sesame (sesamum indicum) landraces germination to salinity stress at different temperature, an experiment was conducted at ferdowsi university of mashhad, collage of agriculture during 2009. experimental type ...

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated in Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn accumulation showed to increase. As a results, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the macrophyt...

Salinity has plagued irrigated agriculture throughout history (Tanji, 1990), and soil salinization is an old–yet– new problem in arid regions. For example, there are approximately 100 million ha of salt–affected soils in China, accounting for one tenth of the total land area (Li, 2009). The development of effective salinity control practices requires an understanding of the causal relationship ...

Despite recent development in producing chemical medicines, associated side effects have led to increased use of medicinal plants and natural compounds. Soil salinity, especially in arid and semi-arid regions, is a serious threat to global agriculture. Nowadays, efforts have been made to find benchmarks that can effectively select salt-tolerant or salt-resistant genotypes. In this regard, the u...

The present study was conducted to assess the physiological and biochemical responses of winter vegetable radish (Raphanus sativus L.) to salinity stress. Salt stress markedly reduced biomass production of both radish varieties. Shoot fresh and dry weights were significantly reduced under salt stress, higher reduction was found at 120 mM NaCl as compared. Salt stress significantly reduced chlor...
