What is ecology?

Today we constantly hear and read about ecology, and there are many reasons for this. Although ecology is one of the youngest sciences, it is of great importance for the future of mankind. Each creature has its own way of life, which depends partly on the creature itself, its activities, and partly on the environment. The environment affects all living beings. And they, in turn, affect the environment. Each organism is only a part of the surrounding world.

At the same time, each organism is part of a group of organisms. They are all together also part of the environment. Therefore, when we study the life of animals or plants in their natural environment, we must also study this environment. A scientist who studies these questions is called an ecologist. His subject of study is ecology, which comes from two Greek words meaning "study of the environment".

Ecology studies the interconnection of living beings in the world and can tell us how to use and conserve our resources efficiently. She can answer, for example, such questions as: "How to better use the land? How to save forests, arable land, all natural life? How to reduce the losses caused by harmful insects?" These are examples of ecologists trying to answer the practical questions that life raises.

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 ... >>

Seals get the flu too 12.08.2000

Epidemiologists have long known that the type A influenza virus is the culprit in all major influenza pandemics, occurring not only in humans, but also in many other mammals, as well as in birds, such as ducks. Another virus, type B, has so far only been found in humans.

Virologist Albert Osterhaus, working at the University of Amsterdam (Holland), recently found influenza type B virus in seals from the North Sea. More precisely, the virus was found in one seal, and in the other - only antibodies to it, but this indicates that the organism of the sea animal has already met with this disease.

The strain of the virus found is almost identical to the one that caused an epidemic among humans in 1995. It seems that it was then that the virus was also introduced to seals, since blood samples from North Sea seals collected before 1995 and stored in a special freezer do not contain the virus, and out of 391 samples taken later, the virus was found in eight. Blood samples are regularly taken from the seals to monitor marine pollution and have material for comparison over the years.

Researchers believe that if you don't want to catch the flu, it's best to stay away from seals just in case.
