Since recent studies on academic English have shown considerable cross-cultural variation in texts written by non-native speakers (Clyne 1987, Ventola & Mauranen 1991, Čmejrková & Daneš 1997, Duszak 1997, Chamonikolasová 2005, Stašková 2005, Mur- Dueňas 2008, Wagner 2011, Dontcheva-Navratilova 2012, Povolná 2012), the paper investigates a corpus of diploma theses written by Czech and German students of English with the aim of fi nding out how novice non-native writers from different discourse communities (Swales 2004) use causal and contrastive discourse markers (DMs) associated with hypotactic and paratactic relations in order to build coherence relations (Taboada 2006) in academic texts. In addition, the author attempts to fi nd out whether there is any variation in the preferences of novice writers depending on the different fi elds of study, i.e. diploma theses written in the areas of linguistics and methodology, and whether the use of selected DMs by Czech and German students differs from the writing habits of native speakers of English.
