Palaeobiological data, supplemented by new 14C dates in conjunction with palaeobotanical and lithological information, have allowed reconstruction of Middle Weichselian (MIS 3) environmental fluctuations in the southern Eastern Baltic region. Palaeoenvironmental reconstructions implying non-glacial conditions during the Middle Weichselian (MIS 3) are supported by the spatial and temporal context of recently discovered remains of Mammuthus primigenius Blumenbach and Rangifer tarandus Linnaeus, 1758. Recording both cold and warm climatic reversals of MIS 3, representatives of the megafauna thrived in an environment characterized by a heterogeneity of vegetation and climate. 14C dating shows that the majority of the megafaunal remains analysed represent the 38–45 cal kyr BP time-interval, which correlates with the Nemunas 2c cold interval (cryomer), and the 31–34 cal kyr BP or Mickñnai 3 thermomer. From pollen data, the palaeovegetation pattern varied from tree-less tundra to birch-predominating forest with an admixture of temporal tree species providing additional information about the diet and habitat preferences of these herbivores in the context of the MIS 3 climatic events.

Quality education enhancement by means of university environmental edification

The submitted work partly describes the historical and actual trends of the introduction of targeted environmental edification at universities based on the framework of Slovakian sustainable development as well as its enhancement of quality educational processes. There has been a need to accentuate environmental consciousness and to bring closer a current state in an incorporating of more environmental and quality aspects for the education process at technical universities. The article emphasizes continuous development of observed problems and introduces the possible future visions from the point of reorganization and tending of study fields. This reorganization requires very a sensitive approach because duplications or triplicities can frequently occur in the environmental education of individual subjects. For this reason students’ interest and ability to learn better can gradually decrease and consequently, results can become worse. Upon graduation, students may not be as well prepared to face the strong competition of the labour market in the Slovak Republic as well as in European Union countries.
