    Opis:
    Reduplication as a word formation process is a relatively under-researched phenomenon in English. The aim of the paper, therefore, is to present different types of derivational reduplication ranging from the prototypical type based on exact repetition to the implied reduplication underlying the word formation process in cryptic rhyming slang. The article also strives to overview the typology of English rhyming slang as this is the domain of language where different types of reduplication abound. The article is written within the theoretical framework of sociolinguistics and morphology and offers ample citational evidence to substantiate theoretical assumptions.

    Opis:
    Currently two morphological species of the genus Fomes (Polyporaceae, Basidiomycota) are known: F. fomentarius (L.) Fr. and F. fasciatus (Sw.) Cooke. Both species are very important in the decomposition of wood and in the nutrient cycling in forest ecosystems. Moreover, F. fomentariusis also known as a source of medicinal and nutraceutical products. Recently the existence of three separate ITS lineages/sublineages among F. fomentarius strains has been clearly established - A1 (the strains isolated from North America), A2 (only from Europe) and B (from Europe and Asia). In this review the current knowledge of the morphological variability of F. fomentarius basidiomata has been summarized in respect of the reliable separation of its lineages/sublineages. Micro- and macrofeatures and geographic variability of the basidiomata have been described. Morphological traits of the F. fomentarius basidiomata can vary due to geographical distribution. These phenotypic differences can be based on the presence of several groups or interactions between the genotype and environment. However, no clear differences between basidiomata, useful for reliable separation of the lineages/sublineages, have been observed so far. A recent description in North American Fomes research articles is based on basidiomata of the A1 sublineage. It is most possible that the descriptions in European literature are based on basidiomata of two other lineages/sublineages and thus we cannot discriminate between them. In the future a detailed study of the macro- and microtraits - pileus and pore surface colors, basidioma size, depth of tube layer, and basidiospore size - is therefore proposed for reliable separation of the lineages/sublineages of F. fomentarius.

    Opis:
    Several protein families of different nature were studied for genetic relationship, correct alignment at non-homologous fragments, optimal sequence consensus construction, and confirmation of their actual relevance. A comparison of the genetic semihomology approach with statistical approaches indicates a high accuracy and cognition significance of the former. This is particularly pronounced in the study of related proteins that show a low degree of homology. The sequence multiple alignments were verified and corrected with respect to the questionable, non-homologous fragments. The verified alignments were the basis for consensus sequence formation. The frequency of six-codon amino acids occurrence versus position variability was studied and their possible role in amino acid mutational exchange at variable positions is discussed.

    Opis:
    A light grey nautiloid conch has a dark brown colony attached to its internal surface. This colonial fossil resembles hederellids and bryozoans, but is in fact a crustoid graptolite (Hormograptus? sp.). The colony has been lithoimmured inside this nautiloid conch by early cementation. Crustoid graptolites were a part of the encrusting communities in the Middle Ordovician of Baltica, but their abundance among encrusters of biogenic substrates reached a peak in the middle Sandbian. The cryptic mode of life appeared very early in the evolution of the crus- toids. The discovery of this crustoid graptolite in a nautiloid conch indicates that the Baltic Middle Ordovician cryptic communities were taxonomically more diverse than was known previously. The nautiloid conch studied is sparsely encrusted with an encrustation density that is similar to those of other Middle Ordovician cryptic surfaces described from Estonia.

    Opis:
    This is the first report of encrusted cryptic surfaces in the Ordovician of Estonia. Only bryozoans and cornulitids occurred in nautiloids and trilobites. Bryozoans were the dominant encrusters, in terms of both the number of specimens and the encrustation area. Stalked echinoderms are common on the hardgrounds in the Middle and Upper Ordovician of Baltica, but the restricted space in nautiloid living chambers and trilobites probably prevented colonization by stalked echinoderms. Cryptic surfaces in nautiloids and trilobites usually are somewhat more encrusted than the open surfaces of hardgrounds in the Ordovician of Estonia. Encrusters presumably favoured cryptic surfaces, as these were less accessible for predators and grazers. Low encrustation densities, compared to North American hard substrates, seem to be characteristic for the Ordovician Baltic Basin.

    Opis:
    In the cold periods of Quaternary climatic fluctuations, many temperate species underwent severe range contractions, and their survival during these periods was associated with climatically more favorable regions, so-called glacial refugia, from which subsequent range expansions took place. In this regard, the relative roles of the Southern (“main”), Northern (i.e., cryptic northern), and Eastern European (e.g., Colchis) refugia in shaping the evolutionary history of European temperate plants should be evaluated. In this study, we investigated the phylogeographic structure of Primula vulgaris, a European mesophilous species, by comparing DNA sequences derived from the nuclear (nrITS) and the plastid (trnL-trnF and rpl32-trnL) genomes of specimens covering the entire distribution range of the species. The variability in flower morphology was also studied on an area-wide scale with geometric morphometry. Our results clearly show the importance of the northern and eastern refugia (the Carpathian Basin and Colchis) as sources of genetic variation among European mesophilous plant species. Primula vulgaris spread initially from the Colchis refugium westwards, and a proportion of the colonists survived during the last glacial period in the Carpathian Basin, which may have served as a secondary center of diversity from which all Europe was subsequently populated.

    Opis:
    The present study aimed to investigate whether adult males could fertilize immature female pupae in the leek (L1) and tobacco-associated (T) Thrips tabaci lineages and to investigate the potential effects of mother to son inbreeding on the appearance of deuterotokous females in the T lineage. To confirm the pupal insemination, a single female pupa was exposed to a single adult male for 24 hours. The removal of a male from the tube that contained the female pupa was made before the female pupa emerged to adulthood. Emerged female adults were isolated and reared individually and the sex of their progeny was determined in the larval stages. To examine a mother and son inbreeding, a single female adult was exposed to her son for 48 hours, and for two consecutive generations, the mode of reproduction was determined by identifying the sex of the progeny. This result showed that pupal insemination was not successful; thus, all the tested females produced only male progeny. Virgin inbred females produced both male and female progeny that refers to deuterotokous reproduction mode. Three virgin females produced a total of 20 females and 75 males in two consecutive generations. A study concluded that deuterotokous mode of reproduction is not a persistent mode of reproduction in the T lineage but is a result of irregularity in the mode of reproduction, and it might be changed because of brother and sister inbreeding and need further studies.

    Opis:
    The name Deroceras panormitanum is generally applied to a terrestrial slug that has spread worldwide and can be a pest; earlier this tramp species had been called Deroceras caruanae. Neither name is appropriate. The taxonomic descriptions apply to a species from Sicily and Malta. This true D. panormitanum and the tramp species are distinct in morphology and mating behaviour. For instance, the penial caecum of D. panormitanum is more pointed, everting faster at copulation. The size of the penial lobe varies considerably In preserved specimens but is always prominent at copulation. D. panormitanum is distinct from the Maltese endemic Deroceras golcheri, but a phylogeny based on mtDNA COI sequences implies that they are more closely related than is the tramp species. D. golcheri has a still closer counterpart on Sicily, but we leave the taxonomy of this “species X” unresolved. In interspecific crosses, D. panormitanum may transfer sperm to the partner’s sarcobelum whereas the partner fails to evert its penis (D. golcheri) or to transfer sperm (the tramp species). Names previously applied to the tramp species originally referred to D. panormitanum or are otherwise invalid, so it is here formally redescribed as D. invadens. Deroceras giustianum Wiktor, 1998 is synonymised with D. panormitanum.
