Abstract Many basins in the Cerrado biome already face increases water disputes caused by agricultural expansion without long-term planning and monitoring of natural resources. The amount timing availability are crucial for socioeconomic development activities climate change resilience enhancement Cerrado. This study relied on a dataset developed to characterize its current status. Different in...

After the scientific development of biotic ligand models (BLMs) in recent decades, these models are now considered suitable for implementation in regulatory risk assessment of metals in freshwater bodies. The BLM approach has been described in many peer-reviewed publications, and the original complex BLMs have been applied in prospective risk assessment reports for metals and metal compounds. B...

Strong, dissolved, copper-complexing ligands are known to control copper speciation and bioavailability in most marine waters. We are testing the hypothesis that metal-responsive production of such ligands occurs in the Elizabeth River estuary, and that picoplankton and bacterioplankton produce the ligands. Recent studies utilizing cultures of marine picoplankton (Synechococcus) and bacteriopla...

One application of plant physiological heat tolerance measurements is the assessment vulnerability to increasing environmental temperatures under climatic change. A thermal safety margin (TSM), difference between and temperature, a common metric for vulnerability. However, there are biological methodological aspects consider when evaluating that have potential substantially alter assessments. T...

This paper introduces the concept of Environmental Security in relation with the parameters of the environment which could affect the availability of essential resources for populations. Water availability and its management are evaluated in different regions of the world and in different environmental conditions and the role of international organisations on this issue has been taken into cons...

The dryland areas of Central Chile are associated to Mediterranean climate. Under these conditions, water availability during crop growth is a crucial factor for crop productivity. Conservation tillage systems play an important role in this area, increasing soil water availability; however, crop yield responses can be variable. Soil management should be aimed at reducing water loss and promotin...

It has been suggested that systemic fluoride absorption from drinking water may be influenced by the type of fluoride compound in the water and by water hardness. Using a human double-blind cross-over trial, we conducted this study to measure c(max), T(max), and Area Under the Curve (AUC) for plasma F concentration against time, following the ingestion of naturally fluoridated hard and soft wat...

Population growth in Indonesia is increasing every year, resulting an need for food. To support maximum agricultural yields irrigation needed as well the availability and demand water irrigation. discharge to irrigate fields. DI Rintau has decreased along with a decrease function of catchment area due existence several soil channels, which can increase possibility seepage or infiltration loss. ...
