Popular Science: Energetic Metabolism of Agriculture in the Czech Republic and Poland after the Fall of the Communist Regime

Popular Science: Energetic Metabolism of Agriculture in the Czech Republic and Poland after the Fall of the Communist Regime

Global processes like climatic changes, growth of the human population and dependence on fossil fuels cause biodiversity loss and the endangerment of whole ecosystems. It is possible that the potential of the biosphere will not be able to satisfy the demands of human production and consumption. Efforts for the sustainability of agricultural production require an increasingly better understanding of energy flow in ecosystems. In agriculture, energy is not only the food foundation, but it is a crucial part in the circulation of elements (esp. carbon) and in the hydrologic cycle.

Popular Science: Astonishing diversity of trypanosomes in frogs

Popular Science: Astonishing diversity of trypanosomes in frogs

If you have ever heard about trypanosomes, probably it was in connection with sleeping sickness and Chagas disease, serious tropical illnesses. It is not so well known that the trypanosomes were actually first discovered in frogs. Many of these parasites can be found also in Czech frogs, though they do not cause human diseases and therefore remain generally neglected. An international research team, in which the Charles University was represented by Jan Votýpka from the Department of Parasitology, made an attempt to gain insight into this little-known world.

Popular Science: Do birds in our forests fare well or not?

One of the factors responsible for decline in biodiversity is land-use change, which is a result of major socioeconomic changes associated with the advancement of human society. And what about forest management? Does it influence species abundance? And how? These and other questions were studied by an international team of scientists. Jiří Reif from the Institute of Environmental Studies and his colleagues were especially interested in associations between environmental changes, forest management and forest bird abundance.

Junior ERC grant is going to the Botany Department

Junior ERC grant is going to the Botany Department

The awarding of a European Research Council (ERC) grant recognizes research of the highest quality. In the category of junior grants for researchers who received their PhDs within the last seven years, only one was given this year in the Czech Republic. Like last year, it was clinched by the Faculty of Science at Charles University. Botanist Filip Kolář can now count on five years of financial support to investigate the importance of multiplying genetic information (polyploidization) in plants. The results of his work will help in understanding evolutionary mechanisms in plants and may even be useful in breeding.

Popular Science: 104.6 km from the confluence, or what is the water quality of Slapy Reservoir?

Popular Science: 104.6 km from the confluence, or what is the water quality of Slapy Reservoir?

In recent decades, there has been a significant improvement in the surface water quality of the main streams of the Czech Republic, mainly because of the decrease of heavy industry and due to the construction of wastewater treatment plants in municipalities over 2000 inhabitants. However, the surface water quality of small rivers is still very low, because they are often found in agricultural areas, which are still affected by fertilizers and other pollutants and many of them also do not yet have wastewater treatment plants. One of these is the Mastník stream in the Central Bohemian Region, which flows into the Vltava River’s Slapy Reservoir. Luboš Mrkva and Bohumír Janský from the Department of Physical Geography and Geoecology at our Faculty have focused on the development and current state of the water quality of this important water body.

Researchers reveal the metabolic capacity of a termite gut protist and its associated bacteria using single-cell (meta)genomics.

Parasitology department´s scientists (Sebastian Treitli a Vladimír Hampl) in collaboration with researchers from University of British Columbia, sequenced the genomes of an isolated individual cell of the protist, Streblomastix strix, and at least eight different species or strains of bacterial symbionts which cover its surface. They used this genomic data to reconstruct the metabolism within this complex symbiotic system.

Popular Science: Judging people by their dustbins

Popular Science: Judging people by their dustbins

Perhaps everyone has some experience with shopping. Just like shopping carts differ, so does the content of the dustbins. Although Czechia occupies top places in waste sorting at present, lots of things must still be improved in waste generation. The knowledge of the population’s differing patterns of behaviour may provide a vital help in this sphere. Researchers from the Department of demography and geodemography Kristýna Rybová, Boris Burcin and Tomáš Kučera, in cooperation with another three scientific centres in Czechia, focused on the research into socio-demographic factors and their influence on waste generation.

Popular Science: Czechs not willing to pay extra for water cleaned of pharmaceuticals

Thanks to the rapid development of analytical laboratory methods, we can now detect the presence of trace concentrations of pharmaceuticals and personal care products in water. The wastewater treatment plants currently in use are, however, often not equipped to completely remove these substances. Zbyněk Hrkal and other scientists from the T. G. Masaryk Water Research Institute and the Charles University Faculty of Science investigated how much Czechs are willing to pay for cleaner water.

Popular Science: Is it possible to save the water from the micropollutants?

Not long ago, they were not known and even today there is still a lack of information about the potentially negative effects of all groups of “micropollutants”. At present, however, together with pesticides, they pose the most significant threat to drinking water quality. What substances do we actually drink and is it possible to remove them? A team of researchers from the T. G. Masaryk Water Research Institute, p. r. i. together with Zbyněk Hrkal and David Rozman from the Institute of Hydrogeology, Engineering Geology and Applied Geophysics of the Faculty of Science is dealing with the question.

Popular Science: Intensive agriculture keeps contaminating groundwater by nitrates

Popular Science: Intensive agriculture keeps contaminating groundwater by nitrates

Nitrates occur in nature naturally, but at higher concentrations they are, in developed countries, also one of the most common contaminants. Nitrates in the human body can be reduced to nitrites, which prevent the absorption of oxygen after entering the bloodstream. This can be particularly dangerous for children and pregnant women. The Hydrogeology Journal published a study by scientists from the Faculty of Science of Charles University and the Czech Geological Survey on factors affecting nitrate concentrations in groundwater that serves as an important water source for Prague and the Central Bohemian Region.

Popular Science: Where are Czech forests under potential risk due to the highest O3 exposures and N deposition?

Nitrogen is known as an essential nutrient for plants. However, its excess amount is harmful to the natural environment, including forest ecosystems. Nitrogen, along with ambient ozone, is currently considered to be one of the main threats for forest ecosystems, in addition to climate change. Therefore, a group of scientists under the leadership of Iva Hůnová from the Institute for Environmental Studies analyzed and indicated the areas of forest ecosystems in the Czech Republic with the highest levels of ambient ozone and nitrogen deposition.

Popular Science: Sewing – when and where was it invented?

Popular Science: Sewing – when and where was it invented?

Clothing plays a very important role in human lives. It is a way of communicating social and individual identity. Moreover, sewing and clothing was of great significance for the history of humans because it enabled man to colonize the cold regions of our planet and to cope with climate change. It is, however, still unclear when, how and where this innovation first appeared. When studying the invention of clothing, needles (made of bone, ivory or antler) represent a proxy for this research. An international team of scientists, among them Martina Lázničková-Galetová from the Hrdlička Museum of Man (Charles University, Faculty of Science) and the Moravian Museum in Brno, aimed to answer questions about the invention of needles and clothing.

She always steps in the same river

Surely everybody noticed that some of his friends (or even he himself) have a certain “type” when it comes to a choice of a romantic partner. Some men prefer blonds, others think that freckles are cute. Some women are attracted to muscles, others like bearded men. How does this observation stand up, however, when we look at it through the eyes of science? And is there a difference between partners we have children with and our other long-term relationships? These are the questions asked by Zuzana Štěrbová, Petr Tureček and Karel Kleisner of the Human Ethology research group, Faculty of Science of Charles University.

Popular Science: Farmers´ markets in Czechia – unique or just a copy?

Between 2009 and 2011, Prague experienced a huge increase in the number of farmers´ markets: from zero to forty-one in the summer of 2011. This phenomenon, which is well-known from the most developed countries, had arrived in Czechia. The question, however, remains: are the Czech markets the same as the markets in the “West”? An assessment of this phenomenon was carried out by Lucie Fendrychová from the Department of Social Geography and Regional Development together with Petr Jehlička.
