Two new species are described inSpadicoides—S. carpatica Hol.-Jech.,S. penatium Hol.-Jech. and three new species inDiplococcium—D. bicolor Hol.-Jech.,D. insolitum Hol.-Jech. andD. parcum,Hol.-Jech.     

Oenothera rostanskii sp. nova from Czechoslovakia

A new species ofOenothera was described which is related toOe. nissensis Rostański. It has been found on three synanthropic localities in Moravian Silesia uptill now.     

Succession of vegetation on dumps from strip coal mining,N. W. Bohemia,Czechoslovakia

Folia Geobot. Phytotax., Praha, 22: 339–354.—The primary succession of vegetation (higher plants) was studied on large dumps from brown coal mining in N.W. Bohemia, Czechoslovakia. Three differently aged stages were investigated (1977–1986), using permanent plots and transects. Changes in the species composition, the participation of life forms, and the species diversity were expressed on the basis of cover data for a period of 30 years of the succession. The data were processed by an ordination technique (DCA).     

Health and environment in Czechoslovakia.

The study summarizes basic information on environmental conditions and health status of the Czechoslovak population. It analyzes the relationships between health and environmental conditions, and Appendix brings the comprehensive results of relevant studies performed in Czechoslovakia. The analytic results suggest the quality of Czechoslovak ecology as unsatisfactory, which in some localities, e.g. North Bohemia coal fields, Prague, Ostrava, is next to critical, with heavy impact on the population's health. The Czechoslovak citizens are more prone to falling ill, die sooner than their peers in the majority of European and non-European countries. In addition to the specific effects of individual factors and life style also immunity, reproduction cycle, metabolic processes etc. become involved in the health-living conditions relationships. All these influences are responsible for high rates of morbidity due to the so-called civilization diseases. Inevitably, the only possible solution is to protect effectively human healthy by protecting his living conditions, i.e. environment and life style.     

Haemogregarina vltavensis n. sp. from perch (Perca fluviatilis) in Czechoslovakia

A new species, Haemogregarina vltavensis n. sp., is described from the blood of perch (Perca fluviatilis) in southwestern Czechoslovakia. Both intra-erythrocytic and free stages interpreted as gametocytes were detected. Only one parasite per erythrocyte was found. It displaces the nucleus and fills most of the volume of the infected host cell. No other developmental stages were discovered.     

Spectral Analysis of the Automatically Recorded Data from Slapy Reservoir,Czechoslovakia

The data for solar radiation (S), air temperature (T_a), surface water temperature (T_w) and pH recorded at 0.5 hr intervals at Slapy Reservoir were subject to spectral analysis. The complete series covered the month of July 1978, where three characteristic sections were distinguished, of which one was characterized by low variations, more irregular values and a slowly decreasing trend and another with high and regular variations as well as a steeply increasing trend. These sections were analysed separately in addition to the complete series. The period of 24 hrs was most important and represented for S, T_a and pH 60, 38 and 18 % of the total variances, respectively. The deterministic periodic component represented 65–95 % of the total variance. The cross-correlation and cross-covariance between selected pairs of variables suggested lags of up to 4.5 hrs, the longest lag being observed for T_w and S. An autoregressive model of the interrelation between the signals was formulated.     

Ochyraea tatrensis gen. et spec. nov., a remarkable pleurocarpous moss from Czechoslovakia

Abstract

A new pleurocarpous moss genus and species, Ochyraea tatrensis Váňa, known only from a single collection from the Nízké Tatry Mts (Czechoslovakia) is described and figured. This genus is placed in the recently described family Hypnobartlettiaceae.     

Coronilla moravica Chrtková etStavělová spec. nova from Czechoslovakia

A new speciesCoronilla moravica (familyFabaceae) is described from the locality ?aklovy N of Uherský Brod in E Moravia, Czechoslovakia.     

Anti-hantavirus antibodies in human sera in Czechoslovakia.

By indirect immunofluorescence using antigens of hantavirus Hantaan and CG 18-20 on Vero E6 cells were examined 5,827 samples of sera from 5,299 probands of Czechoslovakia. In 49 persons (0.94%) were found antibodies of titres 1:32 and higher. Two groups of elderly farm workers showed a cluster of positive individuals amounting to 9.9% and 29.4% respectively. The ratio of positivities in some other, randomly and specifically selected groups was deep below 1%. The partial results for the group of farmers were confirmed by RIA test. Occasionally antibodies only to one of the hantavirus serotypes, at other time, to both were found. The authors discuss the findings of antibodies of the two serotypes in humans as related to the evidenced existence of two hantavirus antigen serotypes in animals.
