    Direct georeferencing with correction of map projection distortions for active imaging

    Get PDF
    In aerial photogrammetry, the Cartesian coordinate system for the description of object space is commonly used. In contrast, many projects have to be processed in the space combined by the composition of a map projection and Vertical datum. In that space, some geometric deformations exist. There are some compensative methods for active and passive sensors. In the case of active sensors, decomposition and the correction of observation vector for each ground point can be used. We obtain height, horizontal distance and horizontal angle in this process. All of these values should be corrected for precise georeferencing. The contribution deals with the derivation of the corrections and gets some theoretical values from the area of the Czech Republic

    Get PDF
    We report the publication of 953 DNA barcodes of forest leaf litter beetles from central Taiwan, in total representing 334 spe- cies of 36 beetle families. This is the first bulk of data from the Taiwanese Leaf Litter beetles project focused on uncovering the under-explored diversity of leaf litter beetles across Taiwan. Based on these data, we provide the first records of the following taxa for Taiwan: family Sphindidae (genus Aspidiphorus Ziegler, 1821); tribes Trichonychini, Ctenistini, and Bythinoplectini (all Staphylinidae: Pselaphinae); genera Gyrelon Hinton, 1942, Thyroderus Sharp, 1885, Cautomus Sharp, 1885 (all Cerylonidae), Dermatohomoeus Hlisnikovský, 1963 (Leiodidae), Paraploderus Herman, 1970 (Staphylinidae: Oxytelinae), Thinocharis Kraatz, 1859 (Staphylinidae: Paederinae), Cephennodes Reitter, 1884, Napoconnus Franz, 1957 (both Staphylinidae: Scydmaeninae), Bicava Belon, 1884 (Latridiidae), Otibazo Morimoto, 1961, Seleuca Pascoe, 1871 and Acallinus Morimoto, 1962 (all Curculioni- dae); species Oodes (Lachnocrepis) japonicus (Bates, 1873) (Carabidae: Licininae), Drusilla obliqua (Bernhauer, 1916) (Staphylin- idae: Aleocharinae) and Coccotrypes advena Blandford, 1894 (Curculionidae: Scolytinae). The records of Anapleus Horn, 1873 (Histeridae) and Batraxis Reitter, 1882 (Staphylinidae: Pselaphinae) have been confirmed. The male of Sivacrypticus taiwanicus Kaszab, 1964 (Archeocrypticidae) is described for the first time. Gyrelon jenpani Hu, Fikáček & Matsumoto, sp. nov. (Cerylon- idae) is described, illustrated, and compared with related species. DNA barcodes associated larvae of 42 species with adults, we are concisely illustrating some of these: Oodes japonicus, Perigona cf. nigriceps Dejean, 1831 (both Carabidae), Ptilodactyla sp. (Ptilodactylidae), Maltypus ryukyuanus Wittmer, 1970 (Cantharidae), Drusilla obliqua, Myrmecocephalus brevisulcus (Pace, 2008), Diochus sp., Mimopinophilus sp. (all Staphylinidae), Stelidota multiguttata Reitter, 1877, Lasiodites inaequalis (Grouvelle, 1914) (both Nitidulidae), Lagria scutellaris Pic, 1910, and Anaedus spinicornis Kaszab, 1973 (both Tenebrionidae). We also report the first cases of Rickettsia infections in Scydmaeninae and Pselaphinae. All data (sequences, metadata, and voucher photos) are made public in BOLD database and in a Zenodo Archive

    This bachelor's thesis introduces social agriculture as an alternative business solution in the whole agricultural sector. This work is not focused just on social agriculture but also on agriculture in general and also on some social terms. It also explains the main meaning in social agriculture, its benefits in social life and for what kind of people it can be beneficial and helpful. It analyzes social agriculture in the Czech Republic and in other European countries.The literal research is divided into three parts. The first part is about agriculture in general and its main functions in agricultural sector. In the second part are described some social terms and the third part which is the longest one is about the social agriculture. The third part also deals with financing of farms or companies that concentrate on social agriculture in each country

Type material. HOLOTYPE: J (NMPC): ‘ INDIA: Arunachal Pradesh (15) / 11 km SSE of Tenga, Eagles / Nest WL Sanctuary, 4.v.2008 / 27º06′23″N 92º26′02″E, 2510 m / Fikáček, Podskalská, Šípek lgt. // Primary evergreen mountain / cloud forest with very sparse / understory vegetation / sifting: wet leaf litter’. PARATYPES: 1 J 9 ♀♀ (NMPC, ZSPC): same data as the holotype. Description. Body length 1.8–2.0 mm (holotype: 2.0 mm). Length of body parts (holotype): head 0.3 mm, pronotum 0.8 mm, elytra 0.9 mm, antenna 0.6 mm. Maximum width of body parts (holotype): head 0.9 mm, pronotum 1.2 mm, elytra 1.1 mm. Body shortly oval (Fig. 26), red-brown with posterior half of head, majority of pronotal surface except margins and large triangular ill-defined patch on base of elytra dark brown. Venter yellow-reddish. Dorsum without microreticulation, punctuate, each puncture with very short and fine seta. Head. Maximum width of head at eyes shortly before their posterior margin. Eyes very flat, narrow, 7× as long as wide in dorsal view. Clypeus feebly emarginate, clypeal line absent. Dorsal surface with very sparsely scattered fine punctures separated by more than 10× their diameter. Mandibles without striking characters. Relative length of antennomeres III: II = 1.7. Pronotum. Widest shortly before base. Lateral sides in basal half of pronotum roundly tapered, then conically narrowed to anterior corners in dorsal view; closely rounded in lateral view (Fig. 27). Puncturation as that of head. Elytra. Broadest approximately at midlength. Punctures as on head and pronotum. Sutural stria absent. Legs.Anterior tarsomere I a little enlarged in male. Tarsi slender in female. Femora simple. Tarsal formula 5-5- 4 in male, 4-4- 4 in female. Mesoventrite. Low longitudinal mesoventral carina present; lateral lines not developed. Metathoracic wings absent. Metaventrite. Femoral lines absent. Both sexes with horn-shaped ventro-caudally oriented process at posterior margin between coxae. Genitalia. Aedeagus as in Figs. 11–12. Operculum small, triangular. Spermatheca as in Fig. 13. Variability. The length ratio of antennomeres III: II varies between 1.7–1.8 in the type specimens; the ratio of length: width of the eyes in the dorsal view being between 6–8. The majority of the paratypes are reddish with a dark vertex and elytral patch. Differential diagnosis. Agathidium (Macroceble) guttiferum sp. nov. resembles A. (Macr.) brancuccii Angelini & DeMarzo, 1981 and A. (Macr.) cochleariforme sp. nov. in the body size, coloration of the antennae, the presence of dorsal puncturation, absence of microsculpture on the dorsum, absence of sutural striae and by the presence of a semivertical process on the metaventrite. It also resembles A. brancuccii in the shape of the aedeagus. The new species differs from A. brancuccii and A. cochleariforme sp. nov. in the longer antennomere III (the length ratio antennomeres III: II = 1.7–1.8 in A. guttiferum, while it is 1.4 in A. brancuccii, and 1.5 in A. cochleariforme), the presence of the triangular darker patch on the elytra, and finally by the slender basal part of the spermatheca (in contrast to the subhaemisphaerical basal portion of spermatheca in both A. brancuccii and A. cochleariforme sp. nov.). The new species also differs from A. brancuccii in the distinctly sparser dorsal puncturation, the tarsal formula in females 4-4-4 (in contrast to 5-4- 4 in A. brancuccii), and by the shape of the median lobe that ends in a small pointed process (in contrast to the simply pointed apex of the median lobe in A. brancuccii). The new species also differs from A. cochleariforme sp. nov. in the very flat and narrow eyes (in contrast to larger dorsal portion of eyes in A. cochleariforme sp. nov., see the description of that species), and by the simple distal part of the parameres (in contrast to the spoon-shaped parameral apices in A. cochleariforme sp. nov.). Etymology. The species name refers to the drop-shaped patch on the elytra. Bionomics. Type specimens were found by the sifting of thick layers of wet leaf litter in the primary evergreen mountain cloud forest with very sparse understory vegetation (M. Fikáček, pers. comm.).Published as part of Švec, Zdeněk, 2012, New Leiodinae (Coleoptera: Leiodidae) from India and Papua New Guinea, pp. 411-424 in Acta Entomologica Musei Nationalis Pragae 52 (2) on pages 418-419, DOI: 10.5281/zenodo.533120
