The Fleming Fjord Formation (Jameson Land, East Greenland) documents a diverse assemblage of terrestrial vertebrates of Late Triassic age. Expeditions from the turn of the 21st century have discovered many important fossils that form the basis of our current knowledge of Late Triassic Greenlandic faunas. However, due to the scarcity and incompleteness of the fossils and their insufficient study, our understanding of the taxonomic diversity of the Fleming Fjord Formation is hindered. Here, we report the preliminary findings of a Polish-Danish expedition to the Fleming Fjord Formation that took place in 2014. Three areas were visited – the fairly well known MacKnight Bjerg and Wood Bjerg and the virtually unexplored Liasryggen. MacKnigth Bjerg and Liasryggen yielded fossils which promise to significantly broaden our knowledge of vertebrate evolution in the Late Triassic. Stem-mammal remains were discovered at Liasryggen. Other fossils found at both sites include remains of actinopterygians, sarcopterygians, temnospondyl amphibians and various archosaurs (including early dinosaurs). Numerous vertebrate trace fossils, including coprolites, pseudosuchian footprints, theropod and sauropodomorph dinosaur tracks, were also discovered. Newly discovered skeletal remains as well as abundant trace fossils indicate higher tetrapod diversity in the Late Triassic of Greenland than previously thought. Trace fossils also allow inferences of early theropod and sauropodomorph dinosaur behaviour.

A Digital Agenda for Europe is one of the seven flagship initiatives of the Europe 2020 Strategy. The main objective of this initiative consists of promoting ICT, especially the Internet, as a strategic tool to improve business, healthcare services, transport and social activity in a better global standard-of-living context. The Europe 2020 Strategy recommends broadband access for all European citizens by 2013 and higher Internet speeds (30 Mbps or above) by 2020. Nevertheless, what is the real position in the European regional and urban context? This article attempts to describe and explain the current situation and trends in relation to the Europe 2020 Strategy initiative.
This paper reports the results of observations of the abundance of population Succisa pratensis Moench, as well as temporal and spatial variabilities of chosen traits such as the number of rosettes, number of leaves per rosette, number and height of flowering stems, number of flower heads per generative stem and number of seeds per fruit. Investigations were conducted in the years 2009−2013, in six patches of Molinietum caeruleae with different dominant species, unmanaged from 10 to 22 years. On the basis of studies performed, the state of populations and chances for maintenance in the colonised site were evaluated.

Disentangling the dendrochronological record of landslide activity from the record of the above-listed factors is all the more difficult because it is not landsliding itself that trees record but the tilting of stems ( Braam et al., 1987 ) ( Fig. 1A ). According to Wiedenhoeft (2013) , the tilt of a tree stem from the upright
