Stocking of reservoirs.

Porzului, anybody that has a pond in the country, wants to revive it: to plant water plants, make a stream or waterfall. And many of the owners of these ponds are installing a fountain, and finally, trigger fish. Stocking of reservoirs is a common phenomenon in our days. And the school of fish not often associated with utilitarian needs, not to feed the family, but for beauty. For aesthetic pleasure. Fish and plants in the pond closely interact.

In the daytime the plants, using the reaction of photosynthesis, water consume carbon dioxide and give back oxygen. Fish breathe this oxygen. In the dark aquatic plants, like fish, consume the oxygen and works the same as the fish exhale carbon dioxide. When plants in the pond the excess, then in the morning, when the concentration of oxygen in water is negligible fish starts to die from lack of oxygen.

M OST fish species, e.g. carp or other herbivorous carp. They eat aquatic vegetation. With one hand they are cleaning the pond of excess vegetation, but on the other hand they can destroy the aquatic plants that you are trying to cultivate. Spending and the stocking of the pond, it is necessary to consider, if you want to have both fish and aquatic plants at the same time. Ie need to consciously choose the right types of plants and fish species for your pond. Continue reading

Marine life “suffocate” from greenhouse gases

Greenhouse gas emissions in the coming decades could have a significant impact on oceanic life forms, with such dire predictions were made by the expert on marine biology Michael Beeman from the University of California in Merced. – Concern about this issue in informed circles is growing because human activity is very rapidly changes the pH (acidity) in the oceans. And although we don’t know what will be the final effect of changing the nitrogen cycle, the experiments are being conducted worldwide, and based on them we can assume that the effect will be global.

According to him, the growth of carbon dioxide emissions, increased by the burning of fossil fuels and other human activity increases the acidity of water, which, in turn, significantly alters the nitrogen cycle in the sea. And because nitrogen is an essential nutrient for living organisms, although, as it turned out recently, some life forms can adapt to other elements, eventually the process will affect all forms of marine life, reports innovanews .

During his research Dr. Beman lowered the pH of water at six different sites in the Atlantic and Pacific oceans. In each case, when pH was lowered, and decreased generation of oxidized forms of nitrogen, which usually uses phytoplankton and drugability. This nitrogen is produced through the oxidation of ammonia in sea water by microorganisms. According to the scientist, these results can be used to assess the potential impact of oxidation on the nitrogen cycle in the sea and marine life forms in General. But the observed effects require additional research. Continue reading
