Background: The aim of this study was to compare the effectiveness of footballers who participated in the 2008 and 2012 European Championships. The study was conducted by analysis of basic technical and tactical game. Material/Methods: The observation method in the form of a kinematic game analysis system was used to collect necessary data. The research material was based on analysis of 304 players participating in the 2008 European Championships and 277 players in the 2012 European Championships, with each tournament consisting of 31 matches. Statistica software was used to apply the Student’s t-test for the independent groups. Results: Higher values of indicators determining player’s efficiency were found in the teams participating in the 2012 tournament; significant differences were found in the total number (p = 0.048) and accuracy (p = 0.034) of shots taken by the most successful teams, in the number (p = 0.044), efficiency (p = 0.002) and accuracy (p < 0.001) of passes as well as in the length of distance covered (p < 0.001). Conclusions: A systematic increase in the efficiency of passes in subsequent tournaments points to an upward trend of this element in the game. An increase was also noted in the number of shots taken, which was accompanied by a decrease in shot accuracy. Modern football has become a fast team game with lots of passes of high reliability. Thus, training of young players should be focused on the development of playing techniques and motor skills.
Twenty new synonyms are proposed for four species of Ceratopogonidae: Atrichopogon rostratus (Winnertz, 1852), Bezzia annulipes (Meigen, 1830), Dasyhelea flavifrons (Guérin, 1833) and Dasyhelea saxicola (Edwards, 1929). Atrichopogon transversalis Kieffer, 1918, A. ventralis Kieffer, 1918, A. homopterus Kieffer, 1919, A. coracellus Kieffer, 1919 and A. nigriventris Kieffer, 1919 are junior synonyms of Ceratopogon rostratus Winnertz, 1852. Bezzia digramma Kieffer, 1925 is junior synonym of Ceratopogon annulipes Meigen, 1830. Ceratopogon obscurus Winnertz, 1852, C. versicolor Winnertz, 1852, C. dufouri Laboulbène, 1869, C. hippocastani Mik, 1888, Dasyhelea brevitibialis Goetghebuer, 1919, D. goetghebueri Kieffer, 1919, D. lignicola Kieffer, 1919, D. sensualis Kieffer, 1919, D. paludicola Kieffer, 1925, D. oppressa Thomsen, 1935 and D. septuosa Borkent, 1997 are junior synonyms of Ceratopogon flavifrons Guérin, 1833. Dasyhelea geleiana Zilahi-Sebess, 1931, D. tecticola Remmert, 1953 and D. karelica Glukhova et Brodskaya, 1997 are junior synonyms of Tetraphora saxicola Edwards, 1929.

The Organising Committee included Jon Ablett, David Aldridge (Chairman), Katrin inse, Richard C. Preece, Tony Walker, and Tom S. White, with support from the members of The Malacological Society of London. The Scientific Committee was composed of 15 scientists. About 120 participants from 24 countries attended the conference, the main representation being from European research centres, but also scientists from Argentina, USA, New Zealand, Hong Kong, and Thailand were present.
