Sampling of 10 sites in 1994–2006 along roads connecting Murmansk with Teriberka and Dalniye Zelentsy yielded 140 species of moths and butterflies. Epinotia immundana and Ortholepis vacciniella are recorded for the first time from the Kola Peninsula, which increased the regional fauna to 690 species. Although some arcto-alpine species have been collected (in particular Sparganothis praecana, Catastia kistrandella, Euphydryas iduna, Glacies coracina), the fauna was clearly dominated by species typical for the forested habitats of the central part of the Kola Peninsula. This result suggests that the ‘routine’ sampling in north-eastern tundra between Murmansk and Ponoj might not be as important in terms of biogeography as it has been expected. Instead, new collecting trips should be oriented to areas with special vegetation, primarily limestone or sandy areas which are more likely to support more eastern and/or arctic species.

The list of all known locality and host records from the literature on louse flies from Slovakia are summarized, with the addition of new collection data. New locality data are provided for five species. Three species are added to the Slovakian list: Icostaminor (Bigot in Thomson, 1858), which was erroneously cited for Moravia instead of Slovakia in the previous checklist, and Ornithophilametallica (Schiner, 1864) and Ornithomyachloropus (Bergroth, 1901), which were overlooked from the last checklist. As a result, the louse fly fauna of Slovakia increases to 19 species: 12 autochtonous species and seven rare, non-native species only occasionally imported to Slovakia or migrating to the country with their hosts. This is by far the largest regional fauna of Hippoboscidae in Central Europe, and matches the richest southern European faunas. In total, 78 host-parasite associations concerning 46 bird-host species from eight orders and nine species of mammals, including humans, have been found from a literature review in Slovakia. Two host-parasite associations are reported from Slovakia for the first time: Ornithomyaavicularia (Linnaeus, 1758) on Prunellamodularis (Linnaeus, 1758) (Aves: Prunellidae) and Lipoptenafortisetosa Maa, 1965 on Homosapiens Linnaeus, 1758 (Mammalia: Hominidae).

The fauna of moths and butterflies of the Western part of the Kola Peninsula is reasonably well documented, while data from Eastern part are scarce, and only five species have so far been recorded from the White Sea shore between Kuzomen and Ponoi. Here we report the results of sampling conducted on June 29–July 2, 2004, in 14 sites along a 150 km stretch between Kuzomen and Pulonga. Among 146 collected species of Lepidoptera, 12 are recorded for the first time from the Kola Peninsula, which increased the regional fauna to 688 species. For Udea nebulalis, which is for the first time reported from Russia, we provide additional records from Karelia.

Abstract The diversity of freshwater gastropods recorded in the Transcarpathian Region of Ukraine is reviewed and comments on their distribution and ecology are provided. Thirty-five species were revealed in samples collected from the lowland and mountainous parts of the Ukrainian Transcarpathia. Three species are recorded for the first time in the regional fauna: Viviparus sphaeridius, Bithynia troschelii and Segmentina montgazoniana. For species found in the region brief remarks on the biotopes in which they were registered and relevant taxonomic comments are given. The most distinctive features of the mollusc fauna of Ukrainian Transcarpathia are considered; the presence as well as the absence of some taxa in comparison with adjacent regions is discussed. The results of our observations confirm that the distribution of gastropod species depends on the types of waterbodies and their altitude location. The presented data contribute to the knowledge of the regional malacofauna and should help to assess the biogeographic status of the Transcarpathian Region more clearly.

Five ant species are reported for the first time from Sri Lanka: Ooceraea alii (Bharti & Akbar, 2013); O. biroi (Forel, 1907); Prionopelta kraepelini Forel, 1905; Strumigenys emmae (Emery, 1890) and S. membranifera Emery, 1869. Among the newly reported species, four species (O. biroi, S. membranifera, S. emmae and P. kraepelini) are known for their invasive and tramping nature, spreading via human commerce and have attained broad cosmopolitan distribution. Impact of these ants on regional fauna is not known and needs immediate attention. A brief diagnosis, distribution, and illustrations are provided for each species.

The bumblebee fauna of the Southern Taymyr region, northern Siberia, is represented by 10 species, i.e., Bombus consobrinus, B. flavidus, B. lapponicus, B. hypnorum, B. jonellus, B. cingulatus, B. balteatus, B. pyrrhopygus, B. hyperboreus, and B. cryptarum. During the field research for this study, 7 species of bumblebee on the Putorana Plateau (or the Putorana Mountains, on the northwestern edge of the Central Siberian Plateau) and 6 species near Dudinka Town were observed and B. consobrinus was found for the first time on the Putorana Plateau. To date, B. consobrinus was known only in the southern and central parts of the Krasnoyarsk Krai. Regarding the regional fauna, Transpalaearctic and Holarctic species are presented. According to the latitudinal aspect, in this region there are arcto-boreal, arcto-temperate, boreal and temperate species. An analysis of the community was carried out regarding bumblebees that live on the Putorana Plateau. It was found that species of the subgenus Pyrobombus and Alpinobombus, that are typical for the tundra and forest-tundra zones in the Northern Palaearctic, are dominant within the bumblebee community.

Although the presence of annulate lamellae was noted in many cell types, including the rat spermatogenic cells, this structure was never reported in the Sertoli cells of any rodent species. The present report is based on a part of our project on the effect of torsion of the spermatic cord to the contralateral testis. This paper describes for the first time, the fine structural details of the annulate lamellae in the Sertoli cells of damaged testis from guinea pigs.One side of the spermatic cord of each of six Hartly strain adult guinea pigs was surgically twisted (540°) under pentobarbital anesthesia (1). Four months after induction of torsion, animals were sacrificed, testes were excised and processed for the light and electron microscopic investigations. In the damaged testis, the majority of seminiferous tubule contained a layer of Sertoli cells with occasional spermatogonia (Fig. 1). Nuclei of these Sertoli cells were highly pleomorphic and contained small chromatinic clumps adjacent to the inner aspect of the nuclear envelope (Fig. 2).

A new Zeiss TEM with an imaging Omega filter is a fully digitized, side-entry, 120 kV TEM/STEM instrument for materials science. The machine possesses an Omega magnetic imaging energy filter (see Fig. 1) placed between the third and fourth projector lens. Lanio designed the filter and a prototype was built at the Fritz-Haber-Institut in Berlin, Germany. The imaging magnetic filter allows energy-filtered images or diffraction patterns to be recorded without scanning using efficient area detection. The energy dispersion at the exit slit (Fig. 1) results in ∼ 1.5 μm/eV which allows imaging with energy windows of ≤ 10 eV. The smallest probe size of the microscope is 1.6 nm and the Koehler illumination system is used for the first time in a TEM. Serial recording of EELS spectra with a resolution < 1 eV is possible. The digital control allows X,Y,Z coordinates and tilt settings to be stored and later recalled.

Microstructural Studies

Microstructural studies by transmission electron microscopy (TEM) of diamond films grown by chemical vapor deposition (CVD) usually involve tedious specimen preparation. This process has been avoided with a technique that is described in this paper. For the first time, thick as-grown diamond films have been examined directly in a conventional TEM without thinning. With this technique, the important microstructures near the growth surface have been characterized. An as-grown diamond film was fractured on a plane containing the growth direction. It took about 5 min to prepare a sample. For TEM examination, the film was tilted about 30-45° (see Fig. 1). Microstructures of the diamond grains on the top edge of the growth face can be characterized directly by transmitted electron bright-field (BF) and dark-field (DF) images and diffraction patterns.

Transmission and analytical electron microscopic studies of scale microstructures and microscopic marker experiments have been carried out in order to determine the transport mechanism in the oxidation of Ni-Al alloy. According to the classical theory, the oxidation of nickel takes place by transport of Ni cations across the scale forming new oxide at the scale/gas interface. Any markers deposited on the Ni surface are expected to remain at the scale/metal interface after oxidation. This investigation using TEM transverse section techniques and deposited microscopic markers shows a different result,which indicates that a considerable amount of oxygen was transported inward. This is the first time that such fine-scale markers have been coupled with high resolution characterization instruments such as TEM/STEM to provide detailed information about evolution of oxide scale microstructure.
