This is an unusual video about the invasion of Asian silver carp caught on Wabash river (Wabash River) in the Midwest, mark Kirby (Mark Kirby) and his partner Brendan Kearns (Kearns Brendan). According to specialists, the most famous lake in the USA and Canada are on the verge of this ecological disaster. Silver carp, imported once from Kazakhstan (behind the ocean it is called Asian carp), has spread to the waterways of the New world with an incredible scale.
It all started with the fact that in 70-e years of the last century of American fishermen, not thinking about the consequences, brought a few specimens of silver carp and silver carp, which were caught in lake Balkhash to “imported” fish destroyed the excess of algae in the Illinois river. As a result of voracious migrant not only coped with the task set before him, but began to seize new territory, harassing the local fish. Now before American experts had a new goal — to prevent the spread of Asian (silver) carp in the Great lakes.
Interestingly, the number of carp in our area, as a rule, regulates the pike, not allowing him to multiply excessively. But in the rivers Illinois and Mississippi Continue reading

Lake Kaffeklubben (detsk. Kaffeklubben Sø, 83 37′) is a small (48 ha) of the eponymous island, North of Greenland, only 707 km from the pole. This is the most Northern lake on the Earth.
For a long time scientists argued about whether to receive life in such places, the impulse to reproduce as a result of nitrate pollution, or make her stop the impending effects of global warming. It seems that an international group of researchers under the guidance of Bianca Perren of the University of Franche-comté (France) managed to answer this question.
Despite the harsh living conditions, once the lake was full Kaffeklubben life in the face of cyanobacteria. The ice over the lake while constant, varying only the thickness. But even under 1-2 m of ice cyanobacteria survive. However, they are most active in summer when the air temperature above the ice reservoir is as high as +1,6 C. But more complex forms of life here. But now, but once…
3 500 years ago, when the lake had just been formed, it occupied several species of diatoms. But, according to studies of lake cores, which the authors said in the journal Geology, about 2 400 years ago, as the local temperature, the population is entirely extinct. Usually, to return, Continue reading
