<abstract><title style='display:none'>Abstract</title> Mechanisms of sex determination in plants are popular research topic. Research studies are initiated to describe sex determination mechanisms and develop molecular methods for sex differentiation in plant species where sexual dimorphism is weakly expressed or absent at the early stages of development. This study presents different mechanisms of sex determination in plants, identifies unexplored areas and discusses problems which limit our knowledge of the subject.</abstract>

Mechanisms of Sex Determination in Plants

<abstract><title style='display:none'>Abstract</title>The article covers the results of a survey of the vascular flora of the peat-bogs and forest swamps of the Kotlina depression in southern Poland. Unexpected concentrations of calcicolous plants are shown to exist and the factors governing their presence are discussed. The discovery of previously unexpected glacial relicts is also examined in the context of the area’s importance in phytogeographical studies of Eastern Europe. A number of observed, but unexplained, discrepancies in the distribution of a small number of relic species have been identified and are given as possible worthwhile lines of further research.</abstract>

Fungus gnats (Diptera: Sciaroidea) of the Gemer region (Central Slovakia): Part 2 - Mycetophilidae

<abstract><title style='display:none'>Abstract</title> Aeshna caerulea (Azure Hawker) is present as a post-glacial relict in central European mountains. This species is listed as critically endangered in the Czech Republic (very restricted distribution occurring in two isolated populations) and the European population trend of this species is decreasing. The main objective of the study was to estimate the population size of A. caerulea in the Úpa bog National Nature Reserve (Czech Republic) using capture-mark-recapture data. Population estimates of adults using the Schnabel method was 425 (the 95% confidence limits: 248.1 / 992.3), and using the Schumacher-Eschmeyer method was 416 (the 95% confidence limits: 326.8 / 570.4). Imago activity became apparent at the beginning of July. This study has suggested that the possible future threats for the A. caerulea in the Czech Republic are drying up, air nitrogen depositions, eutrophication, pollution of water by external sources, and terrestrification, mainly as a result of global warming.</abstract>

<abstract><title style='display:none'>Abstract</title> Field revision of current distribution of mountain hawkweeds (Hieracium s. str.) in the Hrubý Jeseník Mts was undertaken. Hieracium atratum, H. chlorocephalum, H. engleri, H. grabowskianum and H. plumbeum, whose last occurrence was documented many decades or even a century ago, were rediscovered. H. plumbeum was even found in new localities. The occurrence of H. alpinum, H. bifidum, H. chrysostyloides, H. inuloides, H. nigritum, H. prenanthoides, H. silesiacum, H. stygium and H. villosum was ascertained at many of their historical localities and a few new localities were found too. A neophyte species H. mixtum was discovered. Hieracium moravicum was not found. Accurate locality description and population size are provided for each finding. Herbarium revision and excerption of crucial literature were performed to provide historical distribution. Distributional changes as well as threatening and beneficial factors influencing Hieracium species in the Hrubý Jeseník Mts are discussed.</abstract>

<abstract><title style='display:none'>Abstract</title>Several species of the genus Cryptomonas EHRENB. are characterized by the sigmoid (S-shaped) form of their cells under natural conditions. Such species were sampled and studied by the author for decades from the plankton of freshwater lakes, dam reservoirs, fishponds, and peat pools, from among littoral vegetation, as well as in small water bodies overgrown with vegetation. After application of optical microscopes on live or chemically treated specimens, they were measured and depicted. Four species known from literature are demonstrated to be easily determinable, namely Cryptomonas curvata, C. reflexa, C. marssonii, C. gracilis. Two new varieties are described. Cryptomonas borealis is shown as a transient species between straight and sigmoid cells. A special attention is given to the occurrence of pyrenoids and Maupas corpuscles within the cells. The new forma of C. cylindrica is pictured and described, with the antapex of the cells deformed differently from sigmoid species.</abstract>

Based on the published findings (Koštejnová 2013, Slezáková 2014, Gajdošík 2020), unpublished data from museum specimens (2005 – 2013), and data from field surveys (2005 – 2023), a total of 13 bat species were recorded in the urban area of Ostrava in North Moravia. Common species in the area included <italic>Pipistrellus pipistrellus</italic>, <italic>Nyctalus noctula, Eptesicus serotinus</italic>, <italic>Myotis daubentonii</italic>, and <italic>Vespertilio murinus</italic>. <italic>P. pipistrellus</italic> was eudominant species (D = 74.41), followed by <italic>N. noctula</italic> (D = 11.41). <italic>E. serotinus</italic> was a subdominant species (D = 4.59), followed by <italic>M. daubentonii</italic> (D = 3.77) and <italic>V. murinus</italic> (D = 2.45). The occurrence of <italic>M. mystacinus/brandtii</italic> was recendent (D = 1.33), and the occurrence of <italic>M. nattereri</italic> (D = 0.51), <italic>E. nilssonii</italic> (D = 0.51), <italic>P. pygmaeus</italic> (D = 0.31), <italic>Plecotus auritus/austriacus</italic> (D = 0.31), <italic>Pipistrellus nathusii</italic> (D = 0.20), <italic>N. leisleri</italic> (D = 0.10), <italic>M. myotis</italic> (D = 0.10) and <italic>M. brandtii</italic> (D = 0.10) were subrecendent. In the summer season, eudominant species were <italic>P. pipistrellus</italic> (D = 76.84), followed by the <italic>N. noctula</italic> (D = 10.63), subdominant <italic>E. serotinus</italic> (D = 4.74), and <italic>M. daubentonii</italic> (D = 3.89), with <italic>M. mystacinus/brandtii</italic> being recendent (D = 1.37). In the winter season, eudominant species were <italic>V. murinus</italic> (D = 62.50), followed by the <italic>N. noctula</italic> (D = 34.38) and subdominant <italic>P. nathusii</italic> (D = 3.13). However, the species composition inside and outside buildings differed significantly. In the summer season, eudominant species inside buildings was <italic>P. pipistrellus</italic> (D = 99.57), followed by the subrecendent species <italic>V. murinus</italic> (D = 0.29) and <italic>M. daubentonii</italic> (D = 0.14). Outside buildings, <italic>N. noctula</italic> (D = 40.16) were eudominant, followed by <italic>E. serotinus</italic> (D = 17.72), <italic>P. pipistrellus</italic> (D = 14.17), and <italic>M. daubentonii</italic> (D = 14.17), with <italic>M. mystacinus/brandtii</italic> (D = 5.12) was dominant, and <italic>M. nattereri</italic> (D = 1.97), <italic>E. nilssonii</italic> (D = 1.97), <italic>P. pygmaeus</italic> (D = 1.18), and <italic>P. auritus/austriacus</italic> (D = 1.18) were recendent species. In the winter season, eudominant species inside buildings were <italic>V. murinus</italic> (D = 68.75), followed by <italic>N. noctula</italic> (D = 25.00), and the situation was very similar outside the buildings during this period, with eudominant <italic>V. murinus</italic> (D = 56.25) and <italic>N. noctula</italic> (D = 43.75). Two roosts of the maternity colonies <italic>P. pipistrellus</italic> were recorded in city buildings: in Výškovice, Lumírova 10, in a expansion joint near the balcony on the top floor of a panel residential building; and in Zábřeh, Plzeňská 2617/4 and Plzeňská 2617/6, in expansion joints on the top floors of an old panel building used as a hostel and apartment building.

This study summarizes 17-year results of teriological research of small mammal fauna in Košice Zoo (near the village of Kavečany, 48°47’10.04”N, 21°12’3.26”E, 380 – 420 m a.s.l.). The small mammals evaluated in this study were obtained by trapping in three periods (1992 – 1994, 2000 – 2001, 2003 – 2004) and were the results of three diploma theses. In total, 688 small mammals belonging to 13 species of four families Soricidae, Gliridae, Cricetidae and Muridae were recorded by trapping during the study period. Rodents significantly dominated with 8 species, 583 ex. (84.7%) compared to insectivores represented by 5 species, 105 ex. (15.3%). A gradual diversity decline of small mammal fauna was recorded, with only four mammal species confirmed in 2003 – 2004. This marked difference over the last 17 years was probably the result of anthropic modifications of the Zoo area, mainly the cutting of trees and shrubs of the alluvium, technical modifications of the streambeds as well as the deratization of the building areas and animal enclosures. The assemblage’s structure of captured small mammals could also be influenced by other factors, such as the predominant type of traps used, or the number of exposed traps in the vegetation and non-vegetation periods of the year. The obtained results are also a suitable basis and source of information for comprehensive and long-term monitoring in this area, given the epidemiological importance of this group of animals and the possibility of contact with exotic animals.

The study is focused on the distribution of the critically endangered <italic>Lopinga achine</italic> in the Hlučín region, near the border to Poland. <italic>Lopinga achine</italic> has been considered extinct there since the early 1970s. The paper provides data on the current distribution at several new localities in the vicinity of Vřesina near Opava, Píšt, Hať and Děhylov (Silesia). The population of <italic>L. achine</italic> is not abundant in the Hlučín region. Host plant of the larvae is the sedge <italic>Carex brizoides</italic>, which makes it different from most other European populations. Currently, two isolated populations of <italic>L. achine</italic> survive in the Czech Republic (i.e. populations in Silesia and southeastern Moravia). Both the populations are threatened with extinction due to changes in forest management.

<abstract><title style='display:none'>Abstract</title>In the Baltic area, the long-lived dioicous wetland moss <italic>Drepanocladus turgescens</italic> (T.Jensen) Broth. produces sporophytes rarely and at irregular intervals. Based on surveys of sporophyte occurrences at 13 sites in two regions in northern Gotland (Sweden) during three to five years, we ask: (1) Is sporophyte formation associated with precipitation and a precipitation index that considers the dry periods during July-August of the preceding year, when gametangia are formed and fertilization occurs? (2) Does the estimated spore output suffice for the species’ long-term persistence of the (Northern) European population species? In one of the study regions, where <italic>D. turgescens</italic> occurs in depressions, sporophyte formation was associated with the two precipitation parameters. In the other study region, with relatively higher precipitation and exposed occurrences on a slightly sloping bedrock with very little accumulated soil, no such association existed. We suggest that this lack of weather effects results from that the exposed rock habitat requires longer continuously wet periods than the depression habitat to allow for gametangia initiation and development, and fertilisation. Average spore production for six spore capsules, from three Gotland localities was 181,000. Based on the sporophyte counts during the survey years, we estimated the total reproductive output as 411.5 million spores in 2013, and 42.5 million in 2015, in the two respective study regions. Taken together with data on haplotype patterns and considering observations on recent colonisations, we argue that such a relatively low and episodic regional spore production is sufficient to maintain global populations of long-lived species, even if these occur in specialized and geographically restricted habitats.</abstract>
