Práce vychází ze soupisu nálezů badenské a z ní vyrůstající řivnáčské kultury na území severozápadních Čech. Podává přehled stavu výzkumu, nálezové základny a přírodního prostředí sídelních regionů – dolního Poohří a Podřipska, Podkrušnohorského úvalu a středního Poohří, sleduje strukturu osídlení obou kultur a jeho datování. Badenská kultura je zde zastoupena podstatně slaběji než ve středočeských regionech, přičemž spolehlivě doložené je až osídlení z doby mladší fáze středního (klasického) stupně. Datovatelné soubory řivnáčské kultury zase všechny spadají pouze do jejího staršího stupně, což naznačuje, že tato kultura zde existovala kratší dobu než ve středních Čechách, nejspíše z důvodu příchodu kultury kulovitých amfor. Snad ze stejného důvodu zde, na rozdíl od středních Čech, nedošlo k rozvoji výšinných sídlišť. Rozdíly mezi situací v severozáp. a středních Čechách skýtají možnost sledovat na regionální úrovni proměny, k nimž zde v průběhu šesti fází středního eneolitu docházelo. and Baden and Řivnáč culture in northwest Bohemia. The work is based on a list of Baden culture finds and those from the ensuing Řivnáč culture in the territory of northwest Bohemia. It provides an overview of the status of research, the base for finds and the natural environment of the settlement regions – the lower and central Ohře River regions, Říp Hill surrounding and region under Krušné hory/Mts.: the work follows the settlement structure of both cultures and the dating of this settlement. Baden culture is represented here to a significantly weaker extent than in central Bohemian regions and settlement is not reliably documented until the later phase of the middle (classic) stage. On the other hand, the datable Řivnáč culture assemblages fall exclusively into its earlier stage, indicating that this culture existed here for a shorter period than in central Bohemia, most likely due to the arrival of the Globular Amphora culture. Perhaps this is the same reason there was no development of hillforts here as in central Bohemia. The differences between the situations in northwest and central Bohemia offer an opportunity to follow the transformations on the regional level that occurred here during the course of the six phases of the middle Eneolithic period.
We studied the diet of the badger through scat analysis and used seven previously described methods to assess their comparability. Methods compared included those based on frequencies of occurrence of different food items and volumetric methods. Our results showed that, depending on the basic methodological procedure, we could classify methods in two groups: frequencies of appearance and volumetric methods. The depiction of the diet obtained is quite similar within these groups but differs between them, as each group depicts different aspects of the trophic ecology of the badger. In conclusion, we advise the use of more than one method when assessing the diets of badgers or other carnivores. The best option is the use of a frequency-based method combined with one or two volumetric methods.
Bagrichthys majusculus, a new species of bagrid catfish from Indochina, is very similar to B. macracanthus and B. vaillantii, and has been previously identified as the former species. It differs from congeners in having a unique combination of the following characters: relatively large and broad mouth, well-developed oral dentition with homodont teeth, 10–13 gill rakers, moderately-long dorsal spine with 15–27 serrations, 9 pectoral-fin rays, inner and outer mandibular barbels with straight margins, pectoral-spine length 15.8–20.7 % SL (standard length), dorsal-spine length 24.4–32.5 % SL, length of adipose-fin base 46.0–50.7 % SL, adipose maximum height 9.9–10.5 % SL, depth of caudal peduncle 7.1–7.5 % SL, and head depth 14.0–16.1 % SL.
Antiparasitic allogrooming in two adults of Red Fox (Vulpes vulpes) was observed in the Javorie Mountains in Slovakia on 18th April 2016. This rare observation was documented by photographs and video. In this context, the occurrence of ticks on Red Foxes and in fox faeces in Europe is briefly reviewed and discussed. and Ivan Literák.
