Sentences with phrase «for eutrophication»

Figure: Areas where critical loads for acidification are exceeded by acid depositions (top) and areas where critical loads for eutrophication are exceeded (bottom) at 2005 (left) and 2015 (right) emission levels.

Progress is however markedly slower for eutrophication, which is caused by excess nitrogen deposition resulting from emissions of nitrogen oxides (NOx) and ammonia (NH3).

Warming temperatures in the Chesapeake Bay region's streams will have implications for future shifts in water quality, eutrophication and water column layers in the bay.

For years scientists have known that nitrogen and phosphorus, which commonly enter freshwater lakes in chemical fertilizers, play a role in eutrophication — the process by which algal blooms, turbidity, and oxygen deficiencies turn a lake into a dead zone, largely devoid of animal life.

This has consequences for climate models, since more loss of carbon dioxide and mineral nitrogen would have a direct bearing on the soil's contribution to greenhouse gases and eutrophication.

1.6 %: estimated proportion of marine fish species (for which trend data exist) with increasing populations, due to improved conditions including better fishing management and decreased eutrophication

26.6 %: estimated proportion of marine fish species (for which trend data exist) that have declining populations, due to unsustainable fishing, habitat degradation, invasive alien species, eutrophication and climate change

According to a study conducted by marine biologists of GEOMAR Helmholtz Centre for Ocean Research Kiel and Rostock University within the German research network BIOACID (Biological Impacts of Ocean Acidification), eutrophication — that is already known for its negative effects — and rising seawater temperatures could lead to a decline of the bladder wrack in the Baltic Sea.

But after the Nile perch was introduced — for commercial reasons — in the 1950s, and the lake also experienced substantial eutrophication, about half of the cichlid species became extinct.

According to the report, the worst scenario for the Baltic Sea region is worsening eutrophication situation.

Integrated Assessment Modelling for the Protocol to Abate Acidification, Eutrophication and Ground - level Ozone in Europe.

The main areas covered in this work booklet are: Species Classification Distribution of organisms Sampling Predator prey graphs Adaptations Pyramids of biomass Carbon cycle Water cycle Eutrophication Global warming Food security Sustainable fisheries Microprotein Within the booklet are a range of different activities for students to work through to help them remember the content.

Eutrophication by sewage effluent, and / or differential exploitation of shellfish species, for example, may help to explain your observations.

They report in Environmental Research Letters that they examined 740 different production systems for 90 different foods, to calculate levels of land use, greenhouse gas emissions (GHGs), fossil fuel energy use, the nutrient runoff that leads to eutrophication or «dead zones» in lakes and rivers, and the potential for acidification of the waters.

But other elements could potentially also contribute to a collapse: an accelerating extinction of animal and plant populations and species, which could lead to a loss of ecosystem services essential for human survival; land degradation and land - use change; a pole - to - pole spread of toxic compounds; ocean acidification and eutrophication (dead zones); worsening of some aspects of the epidemiological environment (factors that make human populations susceptible to infectious diseases); depletion of increasingly scarce resources [6,7], including especially groundwater, which is being overexploited in many key agricultural areas [8]; and resource wars [9].

In addition to increasing the quantity of organic carbon and reducing the availability of oxygen, eutrophication may also affect the overall quality of organic matter for fueling CH4 - producing archaea.

In southern Europe, to compensate for increased climate - related risks (lowering of the water table, salinisation, eutrophication, species loss)(Williams, 2001; Zalidas et al., 2002), a lessening of the overall human burden on water resources is needed.

These hypoxic areas — virtually uninhabitable for most marine life — are a result of eutrophication, or too many nutrients from fertilizer runoff and sewage discharges finding their way into coastal waters.

«Scientist» seems to agree with Gavin on this, because, despite these ugly numbers, despite the graph that's level for centuries before going hyperbolic in the 20th Century, despite the obvious impossibility of meaningful calibration 1850 - 1995, despite the chapter - and - verse description in Tiljander03 of roadbuilding, peat cutting, farming, bridge reconstruction, and eutrophication — I used the word «absolutely.»

A very shallow lake, its has suffered from eutrophication that has continued for decades, due to increased nutrient load from farming and other human activities.

And you're going with Gavin on this, because, despite these ugly numbers, despite the graph that's level for centuries before going hyperbolic in the 20th Century, despite the obvious impossibility of meaningful calibration 1850 - 1995, despite the chapter - and - verse of roadbuilding, peat cutting, farming, bridge reconstruction, and eutrophication — I used the word «absolutely.»

However, the conditions predicted for the open ocean may not reflect the future conditions in the coastal zone, where many of these organisms live (Hendriks et al. 2010a, b; Hofmann et al. 2011; Kelly and Hofmann 2012), and results derived from changes in pH in coastal ecosystems often include processes other than OA, such as emissions from volcanic vents, eutrophication, upwelling and long - term changes in the geological cycle of CO2, which commonly involve simultaneous changes in other key factors affecting the performance of calcifiers, thereby confounding the response expected from OA by anthropogenic CO2 alone.

Nutrients like phosphorus and nitrogen are necessary for plant growth, but excess nutrients in a water system can cause a dangerous form of pollution known as eutrophication.
