What do beavers eat?

The beaver (or beaver) is a large rodent and, like all other rodents, the beaver has four front incisor teeth. It is with these teeth that he saws the trunks and branches of trees, which he uses for food and for the construction of dams. Thus, the beaver lives mainly on wood, feeding on trunks, branches, young shoots, and roots of aquatic plants.

And why beavers build dams? The fact is that the beaver lives in the water and leads an active lifestyle in the winter. For this, the beaver needs a dam, deep enough so that it does not freeze to the very bottom in winter. Here, in order to increase the depth of the river or pond where he lives, the beaver builds a dam that raises the water level.

To build a dam, beavers lay willow rods, black alder branches or any other branches that are crushed with mud and stones on the bottom of the river. As the dam grows, branches and tree trunks are put as you please. Often the branches take root and intertwine with each other, which further strengthens the dam.

To cut down a tree, the beaver makes two notches on the trunk, one above the other, and scrapes the wood between these notches with his teeth. The beaver cuts a branch 2 cm thick in two bites. Usually, beavers use trunks about 25 cm thick. A tree this size can be cut in one night. In general, beavers prefer soft woods such as alder, poplar, willow or aspen. Since beavers only eat the inner bark of trees, the gnawed trunks and branches can be used to reinforce the dam. In height, the dam usually reaches no more than 2 meters, but it can be very long!

The house of a beaver is called a hut. It can be located on the bank of a river or in a shallow part of a dam. The floor of the hut is above the water level and is covered with algae or wood chips. The entrances to the hut are under water. In late summer or autumn, the beaver stores food for the winter. Logs, branches and bushes are cut and stacked near the hut. These warehouses are sometimes more than 1 m in height and contain hundreds of branches and young trees.

What was Magellan's goal for circumnavigating the world?

Magellan did not at all intend to make a round-the-world expedition - he only wanted to find a western path to the Moluccas and return back. Only the threat of an attack by the Portuguese forced one of the ships to continue to follow west and eventually go around the globe, while Magellan himself died in a battle in the Philippines during the voyage.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Gypsy genealogy 17.08.2006

Australian geneticists led by Lyuba Kalaijieva (University of Perth) analyzed gene mutations in almost two thousand gypsies from different European countries. One of the mutations is found, except for the gypsies, only among Pakistanis and Indians.

Judging by the known mutation rate of human genes, carriers of this altered gene appeared in Eastern Europe, passing through Asia, about a thousand years ago. This result coincides with the theories of ethnographers and linguists about the origin of the Gypsies.

Analysis of the rest of the genes shows that about 400 years after the arrival in Eastern Europe, a relatively small group of nomads split into three. One group remained in the Balkans, another went north of the Danube, and a third moved to Western Europe.

Since the Gypsies have not retained any information about their origin, only molecular genetic studies can clarify their history.
