The paper evaluates changes in the water temperature of the Vistula River – one of the longest rivers in Europe. Mean monthly and annual water temperatures from the period 1971–2017 for 11 stations along the entire length of the river revealed the increasing trends. The mean increase in water temperature in the analysed multi-annual period was 0.31 °C dec–1. In the majority of analysed stations, the key factor determining changes in the water temperature of the river was air temperature. The observed water warming in the Vistula River should be considered an exceptionally unfavourable situation in the context of importance of water temperature for a number of processes and phenomena occurring in river ecosystems. Given the scale of changes, fast measures should be undertaken to slow down the warming.
Der Artikel befasst sich mit der Frage, in wieweit die den Kelten zugeschriebene Latène-Kultur die archäologischen für germanisch gehaltenen Kulturen im mitteleuropäischen Bereich beeinflusste. Der Verfasser schließt, dass ein beschränkter Einfluss auf die Latène-Kulturen lediglich in Mitteldeutschland innerhalb der entstehenden Großromstedter Kultur zu beobachten ist. Im Wesentlichen blieb das Milieu der Elbgermanen in Mitteleuropa in der älteren römischen Kaiserzeit von der Latènekultur unberührt, das sogenante keltische Erbe kann hier in einem größeren Maße nicht erkannt werden. and On the “Celtic heritage” in the early Roman period in Bohemia and Central Europe. The article deals with the problem, in what extent the La Tène culture, ascribed to the Celts, influenced in the Central European area the following archaeological cultures ascribed to the Germans. The author concludes that a limited latènean influence can be observed only in Central Germany in the nascent Großromstedt culture. In general, however, the culture of the “Elbe Germans” remained unaffected by the La Tène culture and the so called “Celtic heritage” cannot be observed.
