Species of the genus Lamellodiscus Johnston et Tiegs, 1922 (Monogenea: Diplectanidae) are characterised by a complex haptor bearing many different attachment elements: two pairs of main hooks joined by medial bars, 14 peripheral marginal hooks and one or two lamellodiscs, formed by several overlapping sclerotised plates (lamellae). These haptoral structures appear gradually during parasite development and, therefore, attachment strategies vary with developmental stage. The main aim of this work was to study the developmental changes of Lamellodiscus theroni Amine, Euzet et Kechemir-Issad, 2007 under experimental conditions, with special attention to the gradual variations in attachment strategies and the pathological implications. Throughout the gradual development of the sclerotised structures, six developmental phases were distinguished in L. theroni: phase I, with only 14 peripheral marginal hooks; phase II, with main hooks (ventral and dorsal) formed; phase III, with ventral bar formed; phase IV, with dorsal bars formed; phase V, with dorsal and ventral lamellodiscs formed; and phase VI, adult stage with male copulatory organ formed. During development, parasites attach to different parts of the first and secondary gill lamellae and the mode of attachment changes from unspecific stage, i.e. based on piercing any flat gill tissue in the early stages, through an intermediate stage when ventral and dorsal main hooks are completely functional and parasites become restricted to the interlamellar space, and finally to the definitive adult attachment stage when lamellodiscs are fully developed. The timing of key events in the development of L. theroni was used to establish adequate intervals for anthelmintic drug administration., Neus Sánchez-García, Juan A. Raga, Francisco E.

On the basis of selected types of supra-regional brooches (A.65, Nauheim, Schüsselfibeln, A.18), an attempt was made to check whether they appeared in the eastern part of Germania in the same chronological Carpathians corresponds to the chronology in the primary distribution zone, no significant differences can be seen. Another picture – obtained, however, from a small number of finds – is drawn for Nauheim type brooches, which seem to remain in use a little longer in the zone between the Carpathian Mountains and the Baltic coast, until the younger stage of the LT D2 phase. Similarly, bowl-shaped brooches (Schüssel-fibeln), probably made mostly in local workshops, were worn in the north for several decades longer than in the zone south of the Carpathian Mountains. In Pomerania they came into use probably slightly earlier than in the area of Przeworsk culture and probably went out of fashion a little faster. This indicates a slightly different rhythm of stylistic and fashion changes between southern and central Poland (Przeworsk culture) and the north – the region of the lower Vistula and the Gulf of Gdańsk. and Cílem článku je ověřit na základě vybraných typů spon vyskytujících se v pozdní době laténské napříč střední Evropou (Almgren 65, nauheimská, lžičkovitá, Almgren 18), zda se tyto spony ve východní části Ger-mánie objevují ve shodném rytmu jako v mateřských oblastech. Obraz používání spon Almgren 65 a 18 severně od Karpatského oblouku odpovídá chronologii v původní oblasti jejich výskytu. Jiný obraz, byť ovlivněný nízkou početností nálezů, se rýsuje pro nauheimské spony, jejichž výskyt na území Polska ukazuje na jejich delší používání, až do mladší fáze LT D2. Podobně lžičkovité spony, vyráběné nejspíš převážně v lokálních dílnách, zde byly používané pravděpodobně o řadu desetiletí déle než v oblasti jižně od Kar-patského oblouku. V pobaltské oblasti se přitom objevily pravděpodobně dříve než na území převorské kultury a také o něco dřív vyšly z módy. To naznačuje rozdílný rytmus stylistických a módních změn mezi Pobaltím, resp. regionem dolní Visly a Gdaňského zálivu, a oblastí převorské kultury v jižním a středním Polsku.
This paper presents preliminary evidence from new excavation at Pavlov I, a well-known Gravettian/Pavlovian site now prepared for the construction of a museum. In addition to the aims of large-scale preparatory and salvage excavations evoked by the construction, our focus was on more detailed stratigraphies of the cultural deposits and on spatial organisation of this extensive settlement. Obviously, Pavlov I has a longer prehistory (including early Gravettian and Early Upper Paleolithic layers in the subsoil) and a more complex spatial structure (including an adjacent mammoth bone deposit) than was previously thought. However processing and interpreting the associated paleobotanical, archaeozoological and archaeological material will be a long-term task., Jiří Svoboda, Martin Novák, Sandra Sázelová., and Obsahuje seznam literatury
Taxonomy, distribution and ecology of Persicaria pensylvanica in the Czech Republic are reviewed. In the Czech Republic, P. pensylvanica is an alien plant which immigrated along the Elbe river. Majority of Czech localities of the species have an ephemeral character but in two localities in the town of Litoměřice, the occurrence is more permanent.
Příspěvek je zaměřen na deskripci a analýzu souboru povelkomoravské a mladohradištní keramiky z lokality Kostice – Zadní hrúd v dolním Podyjí. Metoda zpracování keramického souboru spočívá ve statistické analýze dat. Zpracování rozsáhlého souboru keramiky přispělo k poznání produkce keramiky na jižní Moravě v období po zániku Velké Moravy až do sklonku raného středověku, zároveň se podařilo definovat základní vývojové fáze lokality. and The article provides a description and analysis of an assemblage of post-Great Moravian and Late Hillfort pottery from the Kostice – Zadní hrúd site in the lower Dyje region. The pottery assemblage was processed using the statistical analysis of data. The processing of the large pottery assemblage contributed to an understanding of pottery production in south Moravia in the period following the demise of Great Moravia up to the end of the Early Middle Ages; the basic development phases of the site were also defined.
This study deals with previously unknown manuscripts that the authors have identified and reassembled in an as yet unorganized section of the Jakub Deml fonds in the Museum of Czech Literature. These manuscripts, fragments and variants of some seventy books and dozens of unpublished texts make a significant contribution to our understanding of the genetics and meaning of the work as a whole. They alter our idea of its genre composition and testify to the complex, non-linear chronology of the work. The authors identify three periods in which Deml’s manuscripts have different functions: the first period involves manuscripts and to a limited extent publishing (1896–1911); the second period independent publishing (1912–1941); the third period is the second manuscript period (1941–1961), when manuscripts became the main medium. Subsequently the study comments on the possibilities of a critical edition of the entire work.
The authors deal with the development of the settlement of the Malá Haná region on the border of historical Moravia during the Late Roman Period (stages C3–D1) and during the Migration Period. After the intense settling of settlements by the Suebi with the Roman-provincial, Przeworsk culture and Chernyakhov culture contacts, which culminate in stage D1, there are strong ties to South Moravia and the Central Danube region at Malá Haná in stages D2 and D3, or alternatively to the Danube-East Germanic cultural group from the 5th century (finds of fibulas, buckles, ironwork in the style of Untersiebenbrunn, probably a Hun sax, skeletal grave from Knínice). Through Malá Haná we can assume the movement of the Lombards on their way from Bohemia to South Moravia, as evidenced by the unique finds of parts of the belt garnitures from Jevíčko and probably also by unique finds of swords (spathae) from two other sites.
Práce se snaží přispět k odstranění diskrepance mezi datováním mužských a ženských hrobů na velkomoravských pohřebištích, její příčinou je mj. pozdní datování veligradského šperku. Zabývá se několika stratigraficky nízko uloženými hroby ze Starého Města Na valách, které obsahují vyspělý veligradský šperk. Některé jeho typy vykazují podobnost se šperkem známým z pozdně avarského prostředí, což ukazuje, že veligradský šperk existoval již od počátku velkomoravského období a zřejmě ještě dříve. Vedle Starého Města lze i na některých venkovských pohřebištích (Dolní Věstonice, Prušánky) vyčlenit skupinu ozdob, které tvoří náplň tzv. předköttlašského horizontu, známého z pohřebišť typu Sopronkőhida-Pitten-Pottenbrunn a datovatelného do 4. čtvrtiny 8. století. Sledováním výskytu ozdob typických pro tento horizont lze na raně středověkých pohřebištích na Moravě a jihozápadním Slovensku vyčlenit ženské hroby, které byly uloženy v průběhu staršího velkomoravského období. and On the female jewellery of the Early Great Moravian period. This article aims to contribute to removing the discrepancy between the dating of male and female graves from Great Moravian cemeteries, amongst the causes of which is the late dating of the Veligrad jewellery set. It considers several, stratigraphically low-lying graves from Staré Město – Na valách that contain mature Veligrad jewellery; several of the types display similarities to jewellery known from the Late Avar milieu, which indicates that Veligrad jewellery existed at the beginning of the Great Moravian period and apparently even earlier. It is not only to Staré Město but also to several rural cemeteries (Dolní Věstonice, Prušánky) that the group of decorations comprising the fill of the “pre-Köttlach“ horizon, known from cemeteries of the Sopronkőhida-Pitten-Pottenbrunn type and dated to the last quarter of the 8th century, can be assigned. By following the appearance of decorations typical of this horizon it is possible for Early Medieval cemeteries in Moravia and South- West Slovakia to distinguish female burials interred during the Early Great Moravian period.
