Biogas plants help farmers in Vietnam

Animal excrements, especially those of pigs, are produced in large volumes in Southeast Asia . Where these wastes are not properly treated, negative impacts on natural environment and health of local inhabitants are a consequence.

Climate change will affect fish communities

According to a study by scientists from the Czech University of Life Sciences Prague and the Leibniz Institute of Freshwater Ecology and Inland Fisheries (Berlin, Germany), climate change and land use will cause significant changes in the composition of fish communities in the river network by 2050. The article was published by the prestigious scientific journal Global Change Biology.

SCOPUS: SAB included in the second quartile

University journal Scientia Agriculturae Bohemica (SAB) was ranked 74th amongst 217 scientific journals in the field of Agricultural and Biological Sciences – miscellaneous.

Climate change endangers forests around the world

A recent study in the Nature Climate Change journal, published by an international team of experts from the CULS Faculty of Forestry and Wood Sciences and the Faculty of Environmental Sciences, shows that ongoing climate change will significantly increase the frequency of large-scale calamities of economic forests.

SENOSEČ 2017: Hundreds of rescued animals, new versions of a mobile app and prevention practices

A new version of the Senoseč online mobile app with new profiles for farmers and gamekeepers developed by the Faculty of Economics and Management of the Czech University of Life Sciences will help to save animals during haymaking more efficiently.

Photovoltaic Panel of a New Generation

With the current state of solar technology, an important role is played by the development of materials stable in long-term irradiation and temperature changes, which may be used to develop new PV panels. Scientists from the CULS are testing the possibilities of encapsulating panels in silicone gel.

Medium-chain Fatty Acids Reduce Bacterial Contamination

One of the main causes of foodborne infections of humans in developed countries is microbial contamination of chicken meat by enteropathogenic bacteria. For their effective reduction, it is necessary to reduce the number of the campylobacteriosis and salmonellosis bacterial species in the digestive tract of animals, because the content of the digestive tract is the most common source of resulting contamination of the surface of poultry meat.

Forest Soils Are Significantly Binding Carbon

Soil analyses conducted by the scientists from the CULS in the Orlické Mountains have shown that even in young forest soils the content of soil carbon has increased almost tenfold during several decades.

Special Substance Can Cope with Lead in the Soil

Scientists from the CULS are testing a sorbent that would bind lead in contaminated locations where the contaminated soil cannot be extracted and leakage into groundwater is imminent.

Scientists Tested Biodegradable Deicers

Czech-Polish expedition on the Selma yacht has set a maritime record near Antarctica. This was due to the deicers developed by scientists from the CULS.

New Biopesticides

Due to the concerns raised in consumers by the use of synthetic chemicals in the process of growing agricultural crops, the recent trend is the search for their safe substitutes.

Mathematical Models Help Foresters with Planting

Scientists from the CULS introduced a new and effective way of planting forest tree seed orchards. The new spatial scheme (referred to as “MI design”) supports random crossing, limits self-pollination and in all monitored parameters exceeds the alternative methods of the spatial arrangement of orchards.

Childbirth Affects Microbial Colonisation of Infants

The method of childbirth has a major impact on the composition of intestinal microbiota in early childhood. The numbers of bifidobacteria differ significantly in children born by Caesarean section and those born by vaginal births.

300 Years of Trojmezná through a Prism of Dendrochronological Analysis

A picture of the development of natural spruce stands after the disturbances inside the Bohemian Forest was created with the use of dendrochronological analyses based on the manner of recruitment of juveniles into the canopy and the change of the width of the tree rings increment in older individuals.

Hydrogen Sulfide as an Anti-aging Agent?

Hydrogen sulfide added in small quantities successfully protected porcine oocytes matured in in vitro conditions from death due to their aging. In addition, hydrogen sulfide improved in aging eggs their ability to develop into a foetus.

Fragrant Essential Oils Protect Wood

The greatest efficacy in combating fungal attacks on beech wood has been shown by oils containing substances carvacrol and thymol, found for example in oregano and thyme. It was found by a research of the scientists from the CULS.

Ash from Biomass Is an Important Source of Nutrients

The vast majority of renewable energy comes from biomass combustion, while about 476 million tonnes of ash is generated annually from the burned biomass all over the world. This inorganic part of the fuel, which remains in the boiler after the combustion of the organic matter comprised in the biomass, contains most of the minerals of the original biomass and can be a welcome fertilizer.

How Do Rhinos Communicate?

Only the basic communication features have so far been described in rhinoceroses, even though they have developed a complex system of social interactions. White rhinos have the most developed social system and thus also the widest vocal repertoire out of all the rhinoceros species.

How to Respond to the Drought in the Forests of Central Europe?

Approaches to the options for reducing the negative impact of drought on the condition of forests in the Czech Republic and in the neighbouring states were presented in a study developed by five research centres of the Central European region.

University Scientists Take Part in the Discovery of New Bacterial Species

Molecular genetic methods, such as the sequencing of bacterial genes and even the entire genome bring new knowledge in the field of bacterial systematics. There is an increasing number of newly described bacterial species from various ecological niches.

The Foul-smelling Hydrogen Sulfide Is Beneficial to Mammalian Eggs

Surprising results have been brought by the “foul-smelling” research of Czech and French scientists. They have found that the eggs of mammals produce by themselves otherwise repulsively smelling and highly toxic gas hydrogen sulfide and regulate with its help their preparation for fertilization.

New Findings on the Immunity of the Bees

Bee colonies are exposed in recent years to great pressure from pathogens of which the most important are the Varroa mites and American foulbrood. The research projects undertaken at the CULS indicate that a large role in the immunity of the bees is apparently played by microorganisms, but also by a varied diet and antimicrobial phenols and alkaloids in nectar and pollen.

What is the Cause of the Faster Growth of Silver Fir?

Some authors assume that the recent climate change is the most important factor causing the higher increment, while others have indicated that the regeneration of the fir and spruce growth was significantly contributed by the rapid reduction in emissions over the last 30 years. The results of the study carried out in Slovakia by experts from the CULS point to a combination of both factors.

Transformation of Variables Facilitates the Analysis of Quasilinear Experimental Dependences

The transformation of variables proposed by the experts from the CULS allows capturing the subtle changes in the course of experimentally obtained results.
