Notes to the use of Aulacoseira taxa in the palaeoecological reconstruction of the Bohemian forest lakes
Aulacoseira taxa are the most abundant members of diatom
assemblages in Prášilské
Lake (Czech Republic) during the Holocene. These dominant
diatom taxa were studied in freshwater
lacustrine sediments in order to harmonize data for
subsequent diatom-based palaeoecological
reconstruction. Nine taxa were distinguished within the
genus, six of them (A. alpigena, A. lacustris,
A. laevissima, A. lirata, A. perglabra, A. valida) showed
clear features for identification, the rest
three taxa (A. nivalis, A. pfaffiana, A. aff. tenella)
required deeper analysis. We decided to use taxa
in species rank, A. nivalis (W. Smith) English et Potapova
and A. pfaffiana (Reinsch) Krammer, in
spite of their hardly odds and the earlier suggested merging.
Morphology of A. aff. tenella was also
discussed in detail. Despite all endeavours, to distinguish
some specimens belonging to the A. distans
species complex using light microscope is impossible and a
classification into the aggregates is
needed. We suggested counting the valve face views and the
valve mantle views separately, in order
to repair subsequent potential misidentifications more
simply
Změny dostupnosti živin zachycené dlouhodobou sukcesí jezerních rozsivek
An examination of primary production in lakes shows regular trends during the Late Glacial and the Holocene periods: an increase ('eutrophication') and a decrease ('oligotrophication') usually connected with the input of terrestrial organic matter ('dystrophication'). Although nutrient availability usually influences production, other abiotic and biotic factors enter lakes' complex ontogeny, such as light availability, mixing regime, pH level, mechanical disturbance, predation or competition. Consequently, the past relationship between nutrient availability and primary production contains important information about the drivers of ecosystem functioning in the past. The reconstruction of past processes relies on the sensitive response of aquatic organisms to environmental changes. Their subfossil remains record the dynamic processes in the sediments and reveal both the local lacustrine history and more global events. Among other organisms, diatoms fulfil their function as a valuable proxy of past physical and chemical properties of water bodies. Whereas the record of planktonic diatom species dynamics represents the general ecosystem condition, variations in species-rich littoral periphytic diatoms add necessary insight into finer environmental fluctuations. The presented research combines...Ve vývoji jezerní primární produkce během pozdního glaciálu a holocénu lze vysledovat ustálené trendy: postupný nárůst produkce - "eutrofizaci" a naopak pokles produkce - "oligotrofizaci", často spojenou s přísunem organické hmoty z povodí - "dystrofizací". Kromě nejčastějšího ovlivnění produkce dostupností živin, vstupuje do komplexního jezerního vývoje řada abiotických a biotických faktorů jako dostupnost světla, režim míchání, pH, mechanické disturbance, predace nebo kompetice. Vztah dostupnosti živin a primární produkce v minulosti v sobě tedy skrývá důležitou informaci o všech těchto faktorech ve fungování jezerního ekosystému. Rekonstrukce minulých procesů vychází z citlivé reakce vodních organismů na změny prostředí. Jejich subfosilními zbytky se do usazenin ukládá záznam o dynamických procesech, které odhalují historii konkrétních jezer ale i události celosvětového rozsahu. Mezi organismy, z nichž lze rekonstruovat minulé fyzikálně chemické podmínky, patří významné postavení rozsivkám. Zatímco planktonní rozsivky přináší spíše informaci o celkovém stavu jezera, změny v druhově pestrém společenstvu perifytických rozsivek umožňují vhled do jemnějších změn ekosystému z pohledu litorálu. Předkládaný výzkum pátrá po komplexních procesech v jezerním vývoji propojením kvalitativní a kvantitativní...Department of BotanyKatedra botanikyPřírodovědecká fakultaFaculty of Scienc
Thinness, overweight, and obesity in 6‐ to 9‐year‐old children from 36 countries: The World Health Organization European Childhood Obesity Surveillance Initiative - COSI 2015-2017
In 2015-2017, the fourth round of the World Health Organization (WHO) European Childhood Obesity Surveillance Initiative (COSI) was conducted in 36 countries. National representative samples of children aged 6–9 (203,323) were measured by trained staff, with similar equipment and using a standardized protocol. This paper assesses the children's body weight status and compares the burden of childhood overweight, obesity, and thinness in Northern, Eastern, and Southern Europe and Central Asia. The results show great geographic variability in height, weight, and body mass index. On average, the children of Northern Europe were the tallest, those of Southern Europe the heaviest, and the children living in Central Asia the lightest and the shortest. Overall, 28.7% of boys and 26.5% of girls were overweight (including obesity) and 2.5% and 1.9%, respectively, were thin according to the WHO definitions. The prevalence of obesity varied from 1.8% of boys and 1.1% of girls in Tajikistan to 21.5% and 19.2%, respectively, in Cyprus, and tended to be higher for boys than for girls. Levels of thinness, stunting, and underweight were relatively low, except in Eastern Europe (for thinness) and in Central Asia. Despite the efforts to halt it, unhealthy weight status is still an important problem in the WHO European Region.The authors gratefully acknowledge support from a grant from the

Urban and rural differences in frequency of fruit, vegetable, and soft drink consumption among 6–9‐year‐old children from 19 countries from the WHO European region
In order to address the paucity of evidence on the association between childhood eating habits and urbanization, this cross-sectional study describes urban–rural differences in frequency of fruit, vegetable, and soft drink consumption in 123,100 children aged 6–9 years from 19 countries participating in the fourth round (2015-2017) of the WHO European Childhood Obesity Surveillance Initiative (COSI). Children's parents/caregivers completed food-frequency questionnaires. A multivariate multilevel logistic regression analysis was performed and revealed wide variability among countries and within macroregions for all indicators. The percentage of children attending rural schools ranged from 3% in Turkey to 70% in Turkmenistan. The prevalence of less healthy eating habits was high, with between 30–80% and 30–90% children not eating fruit or vegetables daily, respectively, and up to 45% consuming soft drinks on >3 days a week. For less than one third of the countries, children attending rural schools had higher odds (OR-range: 1.1–2.1) for not eating fruit or vegetables daily or consuming soft drinks >3 days a week compared to children attending urban schools. For the remainder of the countries no significant associations were observed. Both population-based interventions and policy strategies are necessary to improve access to healthy foods and increase healthy eating behaviors among children.The authors gratefully acknowledge support from a grant from the

Methodology and implementation of the WHO European Childhood Obesity Surveillance Initiative (COSI)
Establishment of the WHO European Childhood Obesity Surveillance Initiative (COSI)has resulted in a surveillance system which provides regular, reliable, timely, andaccurate data on children's weight status—through standardized measurement ofbodyweight and height—in the WHO European Region. Additional data on dietaryintake, physical activity, sedentary behavior, family background, and schoolenvironments are collected in several countries. In total, 45 countries in the EuropeanRegion have participated in COSI. The first five data collection rounds, between 2007and 2021, yielded measured anthropometric data on over 1.3 million children. In COSI,data are collected according to a common protocol, using standardized instrumentsand procedures. The systematic collection and analysis of these data enables inter-country comparisons and reveals differences in the prevalence of childhood thinness,overweight, normal weight, and obesity between and within populations. Furthermore,it facilitates investigation of the relationship between overweight, obesity, and poten-tial risk or protective factors and improves the understanding of the development ofoverweight and obesity in European primary-school children in order to supportappropriate and effective policy responses.The authors gratefully acknowledge support through a grant from

Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020
We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation, compare the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2
Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)
From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions

Changes in nutrient availability imprinted in long-term diatom succession in lakes
An examination of primary production in lakes shows regular trends during the Late Glacial and the Holocene periods: an increase ('eutrophication') and a decrease ('oligotrophication') usually connected with the input of terrestrial organic matter ('dystrophication').

Pretreatment of hops for further processing in beer technology
This diploma thesis deals with pre-treatment of hops for further processing in beer technology. In the experimental part of the work, the effect of low temperatures, as pre-treatment of hops, on the monitored parameters was observed. Three types of cold pretreatment were used. In two cases, the hop material was frozen using a freezer at -25 ° C and in the second case at -70 ° C. In the third case, the hop material was treated by contact with liquid nitrogen in combination with mechanical treatment. The variety of hop materiál was Žatecký poloraný červeňák, which were in the form of pellets or pressed hop cones. The total bitterness of the samples, the total content of phenolic substances, the total content of flavonoids, the antioxidant activity and the concentration of essential oils, specifically myrcene humulene and geraniol, were examined. The effect of pre-treatment was investigated during conventional worth boiling as well as dryhopping. The experimental part includes descriptions of the hopping process, descriptions of individual analytical methods. A parallel measurement was performed on each sample. Significant advantages or disadvantages of some of the pretreatments were not demonstrable, however, the most significant differences were observed in samples hopped with hops pretreated by freezing at -70 ° C, which had a positive effect on the amount of extracted essential oils during cold hops
