Studie představuje výsledky výzkumu zaměřeného na psychologické dopady spojené s epidemií covid-19 v České republice v průběhu měsíců březen–květen 2020. Cílem studie je sledovat a popsat dynamiku psychologických ukazatelů v čase, s ohledem na vývoj situace v ČR – od prvního nárůstu počtu nakažených a výrazných restrikcí, přes kulminaci a ústup první vlny epidemie, až k pomalému návratu do stavu uvolněných restrikcí. Výzkum pracuje se souborem 2716 respondentů ve věku 18–89 let, kteří se zúčastnili on-line dotazníkového šetření, případně byli dotazováni trénovanými výzkumnými asistenty (zejm. v případě seniorů a dalších osob, kteří neměli přístup k internetu). Výzkumná data zahrnovala deskriptivy účastníků a výsledky psychologických testů zaměřených na emoční stavy respondentů, jejich psychický nepokoj (distres) a přítomnost úzkosti a deprese. Tyto psychologické ukazatele byly sledovány jak v celém souboru, tak ve skupinách podle pohlaví a věku. Výsledky dokládají, že nastalá epidemická situace souvisela s výrazným nárůstem negativního emočního prožívání, se symptomatikou psychického nepokoje, úzkostí a depresí, a to až do období kulminace. Poté bylo zaznamenáno postupné zlepšování psychického stavu dotazovaných osob. Negativní dopady byly výraznější v populaci mladších dospělých a v populaci žen. Výsledky poukazují také na rozdílnosti v míře reportovaného stresu u izolovaných osob, které byly dotazovány zprostředkovaně (asistenty), oproti osobám, které reportovaly svůj stav přímo do dotazníku. V případě nezprostředkovaného dotazování byly hodnoty negativních psychických ukazatelů vyšší, oproti osobám, které byly dotazovány asistenty. and The study presents the results of a screening focused on the psychological impact associated with the outbreak and further development of COVID-19 pandemic in the Czech population during March – May 2020. The aim of the study was to investigate temporal dynamics of psychological impact covering the first wave of the epidemic, i.e., first phases of the epidemic growth, culmination, decrease, and slow return to a normal lifestyle. The sample of 2716 respondents aged between 18 and 89 years participated in an online survey from March 18th to May 25th, 2020; part of them (typically seniors and others, who had not access to the internet) were assisted in entering the data by trained interviewers. The survey comprised questionnaires capturing emotional states, psychological disturbance, anxiety, and depression. The changes in the scores by pandemic phase (time frame) were studied for the whole sample and for gender and age groups. The results show that the threat of COVID-19 caused a significant increase in negative emotional experience and in the symptoms of psychological disturbance, anxiety, and depression in the Czech population in time of infection culmination, even when the spread of the pandemic was well controlled, and then a gradual decline over time. The data indicated that the pandemic situation had a more pronounced impact on women and younger adults. The study also showed that in situations of pandemic stress associated with isolation, when isolated people are interviewed about their mental state, their reports on negative experiencing might be significantly reduced compared to direct anonymous selfreports data entry.
Specimens of Viola elatior (VE), V. pumila (VP) and V. stagnina (VS) in 40 Austrian, Czech and Slovak public herbaria were revised, a total of almost 1750 specimens from the three countries. Apart from VE, the quality of the original identifications was rather poor, especially of VS, which was frequently confused with VP and V. canina. This, together with the confusion of nomenclature that persisted during the 19th century, made the old literature records unreliable. Hybrids are usually difficult to identify and are rarer than generally believed. VS and VP have similar distribution patterns: they occur mainly on floodplains of large lowland rivers and in adjacent hills in the N part of Bohemia, S and Central Moravia, E Austria and S Slovakia; they may be classified as river corridor plants. VS differs from VE and VP mainly by its presence in S Bohemia and its absence from large parts of S Slovakia, as well as its rarity in Austria and Slovakia. All three species grow predominantly in regions with a relatively warm and dry climate: most localities are situated in regions with a mean annual temperature of 7–11 °C and mean annual precipitation 401–700 mm. A temporal analysis of records revealed that all three species are declining in all three countries: generally, this decline is weakest in Austria, with 46–61% of grid cells with occurrences confirmed after 1980 (compared with the number of grid cells with records for 1801–2008), and strongest in Slovakia, with 18–32% of grid cells with occurrences confirmed after 1980. The decline is due mainly to the canalization of rivers and subsequent changes in land use, urbanization and recently afforestation. VE may also be endangered by modern forestry practices. The inclusion of all three species in national Red Lists and subsequent conservation measures are justified and necessary, though national Red List status may differ between countries.
