New Diagnosis

Actinopterygians from the Permian sediments of the Czech part of Intra-Sudetic Basin, occurring in the Ruprechtice and Otovice Limestone horizons (Broumov Formation), are revised and redescribed based on both old material and newly discovered specimens. A new diagnosis and reconstruction of Paramblypterus vratislaviensis (Agassiz, 1833), the most numerous actinopterygian of the Ruprechtice Limestone Horizon, and the rare Paramblypterus zeidleri (Fritsch, 1895) are published. First actinopterygians from the Otovice Limestone Horizon were described. Most of the specimens from the Otovice Limestone are referred here to Paramblypterus cf. rohani and Paramblypterus sp. Representatives of Aeduellidae have also recently been discovered in the Otovice Limestone. Osteological fragments belonging to a new taxon exhibit the diagnostic features of the genera Aeduella and Bourbonnela. The reasons for the significantly different faunistic content in the stratigraphically close Ruprechtice Limestone Horizon and Otovice Limestone Horizon are discussed.

AbstractLymnaeid snails of the genus Radix serve as intermediate hosts of some schistosomes and fasciolids. In Europe, delineation of species within the genus Radix is unresolved and, therefore, spectrum of snail hosts susceptible to trematode infections is under discussion. We used and compared three criteria for species delineation using snails collected at 43 localities. (a) Sequence analysis of ITS-2 rDNA disclosed that the collected snails belong to four species — R. auricularia (Linnaeus, 1758), R. peregra (Müller, 1774), R. lagotis (Schrank, 1803) and R. labiata (Rossmaessler, 1835) (criteria and names are based on the work of Bargues et al. 2001). Occurrence of R. peregra in the Czech Republic was confirmed by molecular data for the first time. (b) Characterization of reproductive system disclosed differences in location, size and shape of bursa copulatrix and its ductus. Unfortunately, some R. labiata specimens shared morphological features of reproductive organs with R. lagotis. (c) Statistical analysis of shell morphology proved that significant differences exist among particular species. One prediction model showed that correct classification of species may be achieved in 82-84% of cases. However, identification of individual snails in the field (without knowledge of respective snail population and use of statistical tools) still remains a complicated issue due to overlaps of shell characteristics. Concerning the role in trematode transmission, R. lagotis, R. labiata and R. peregra are susceptible to Trichobilharzia regenti. Also, successful experimental infections of R. lagotis and R. labiata by Fascioloides magna were accomplished.

The rare hyolith Alfaites romeo gen. et sp. nov. is described from the lower half of the middle Cambrian (Drumian) Buchava Formation of the Skryje-Týřovice Basin in the Barrandian area of the Czech Republic. This new taxon is based on excellently preserved external and internal moulds of three opercula and several conchs collected from carbonate nodules and shale. This rare species has been established at three separate outcrops in the lower part of the Biozone of Paradoxides (Eccaparadoxides) pusillus (Barrande 1846). Morphology of conch and both external and internal surface of operculum are well known. However, specific morphology excludes assignment to any predescribed hyolithid family.

AbstractThe composition of the land snail fauna of central Europe is responsive to environmental conditions and undergoes changes throughout the Holocene. That holds also for the fauna of central-European Helicellinae, a group of dry-adapted western Palearctic snails with five species living in the Czech Republic. While one of them is currently spreading in the country, two, Candidula unifasciata and Helicopsis striata, are critically endangered, both with only a single surviving population. Although sharing a similar fate lately, these two species represent completely different histories. While C. unifasciata is a rather recent immigrant in the area, H. striata is a relict species of the Pleistocene loess steppe, which is declining during the Holocene. However, the origin of the only known extant Czech population of H. striata is deemed to be dubious due to the untypical habitat inhabited, and within C. unifasciata two species or subspecies used to be distinguished, suggesting a dual origin of its populations. We present here sequences of a fragment of the 16S rRNA gene from two extinct and the last surviving populations of H. striata, and from two extinct populations of C. unifasciata from Bohemia, supplemented by Slovak samples of both. The obtained haplotypes of Bohemian C. unifasciata are different from the one found in western Slovakia, suggesting a different origin of the Western Carpathian populations. The sampled extinct Bohemian populations of H. striata shared an identical haplotype with the last living population, supporting native origin and conservation value of the latter. The causes of the disappearance of the two species are discussed

AbstractCentral Europe in general is poor in Teloschistaceae lichen crusts (Caloplaca s. lat.). Diversity of these lichens is increased by the occurrence of some Arctic, Mediterranean and continental species, which are here close to the limits of their range. Examples include: 1)Caloplaca interfulgens, previously known from arid territories of northern Africa and western Asia, is recorded, surprisingly, from Austria, Czech Republic, Germany, Slovakia and southern Russia. In Central Europe, it is restricted to scattered xerothermic limestone outcrops.2)Caloplaca scabrosa, previously known only from Svalbard, is recorded from the Sudetes in the Czech Republic. It is similar to, but not conspecific with, C. furfuracea. Its diagnostic characters include a blastidiate thallus and the presence of atranorin. Our results show that atranorin is absent in the majority of taxa related to C. furfuracea with only two exceptions: the sample from Eastern Carpathians, here called C. aff. scabrosa, and in one Sudetan sample identified as C. crenularia.3)Caloplaca emilii, newly described below, is closely related to the Mediterranean C. areolata. We consider C. emilii a Mediterranean species rarely occurring in higher latitudes in Austria, the Czech Republic and Germany. It is distinguished from C. areolata mainly by the presence of vegetative diaspores (blastidia); a possible role of blastidia in the distribution pattern of C. emilii is discussed below. Status of the names Caloplaca areolata, C. isidiigera and C. spalatensisis, formerly used for the new taxon, is clarified.4)Caloplaca molariformis, newly described below, belongs to the Pyrenodesmia group (a lineage of Caloplaca without anthraquinones). It is a continental species, frequently collected on limestone or lime-rich tuffs in steppes or deserts in Turkey, Iran, western Kazakhstan and southern Russia, and is also known from eastern Ukraine and southern Slovakia. Caloplaca molariformis is characterized by its thick thallus with fungal and algal tissues arranged in high stacks.5)Caloplaca substerilis, newly described below, is distinguished from the closely related C. ulcerosa by its endophloeodal or minutely squamulose thallus with soralia formed in bark crevices or on margins of squamules. While C. ulcerosa has a maritime distribution in Europe, C. substerilis is typically a continental species. North American continental lichens called “C. ulcerosa” are phylogenetically closer and more similar to C. substerilis.The positions within Teloschistaceae of the taxa considered are demonstrated by ITS phylogenies. The distributions of C. areolata, C. emilii and C. interfulgens are mapped. The new species are fully described using more than a hundred phenotype characters, and diagnostic characters are indicated separately.

A New Species

Thinouia is a Neotropical genus of lianas with approximately 12 species and is the only genus in tribe Paullinieae with actinomorphic flowers. During a taxonomic revision of the genus and fieldwork in south-western Amazonia, we found a new species that appears similar to Thinouia trifoliata (ex Allosanthus) because of its racemiform inflorescence. However, before describing the new species, we had to confirm that Allosanthus was congeneric with Thinouia so we could place the new species in the correct genus. The results of the phylogenetic analysis, based on molecular data (trnL intron and ITS sequences), show that Allosanthus should be included in Thinouia. Thus, the new taxon is described here as Thinouia cazumbensissp. nov. The new species is described, illustrated and phylogenetic trees showing relationships within supertribe Paulliniodae and Thinouia and the congeneric Allosanthus are given.

Abstract. The aim of the study was to evaluate changes in the gene pool of a dog population during the period of its formation. Pedigree and mtDNA analyses were performed on the Polish population of Hovawart dogs. A total of 192 litters of 93 dams and 115 sires were born between 1988 and 2008. Breeding began using Hovawarts imported mainly from the Czech Republic and Slovakia; however, the role of Western European dogs increased continually throughout the period analysed. No unfavourable effects caused by the limited size of the population were identified because of the constant inflow of new genes from abroad. The continual increase in the gene pool was indicated by all of the pedigree parameters analysed. Two different mtDNA haplotypes were found, and complete agreement between pedigree and molecular data was noted. The results of the analyses permit concluding that the process of formation of the new Hovawart population was also impacted by non-genetic factors that directly influenced the composition of gene pool.

High Diversity

AbstractDespite being considered a classical example of protective Batesian mimicry hoverflies (Syrphidae) are known to be preyed upon by various passerines. The aim of the present study was to examine in detail food brought by reed warblers Acrocephalus scirpaceus to their nests to better understand the importance of hoverflies in the diet of small passerines. Using neck collars, 273 food samples containing 8,545 food items delivered to reed warbler and parasitic common cuckoo Cuculus canorus nestlings in warbler nests were recorded. The study was conducted during three breeding seasons in South Moravia, Czech Republic. An unusually high diversity of hoverflies was found — 27 species, including Mesembrius peregrinus (critically endangered species in the Czech Republic) and Mallota cimbiciformis (endangered species) — a new taxon to the Czech Republic. This indicates that nestling diet analyses may provide not only information on avian foraging behaviour but also important faunistic data. Thus, without the detailed identification to species level of material from foraging behaviour studies valuable scientific information may be lost. Overall dominance of Syrphidae was 3.7%, the most common species being Episyrphus balteatus (55.7%, n = 318). However, this number seriously underestimates the importance of hoverflies in the diet of reed warblers as hoverflies are one of the largest prey taken by warblers. Both larvae and pupae were rare, imagines strongly dominating (92.7%). Both specific wasp mimics (e.g., Chrysotoxum verrali) and bee mimics (e.g., Eristalis spp.) were not avoided by foraging reed warblers. The presence of a parasitic cuckoo chick did not affect host foraging behaviour with respect to overall dominance of hoverflies in the diet (warbler 3.3%, cuckoo 3.8%).
