1. Germination characteristics of Salicornia patula Duval-Jouve, S. emerici Duval-Jouve, and S. veneta Pign. et Lausi and their occurrence in CroatiaNina Šajna, Marjana Regvar, Simona Kaligarič, Željko Škvorc, Mitja Kaligarič, 2013, original scientific article Abstract: According to recent molecular analyses of Salicornia, we revised the annual glassworts from the Croatian coast, classified until now only as Salicornia europaea. Two species, a diploid Salicornia patula and a tetraploid S. emerici were recognized. They can be easily distinguished by floral characters, but not only by their habitus, which varies extremely according to environmental factors. Both species differ also in seed morphology. Salicornia patula has dimorphic seeds, with larger central seeds reaching high germination rates. Germination patterns helped to explain the habitat preferences. The species rarely co-occur, however. The rare S. patula occupies drier habitats, on coastal mudflats or sands that are irregularly inundated. It occurs within the assoc. Suaedo maritimae-Salicornietum patulae. Salicornia emerici occupies the lowest coastal mudflats, regularly inundated, where nutrient-rich conditions prevail, and forms an almost monotypical assoc. Salicornietum emerici. Due to the synonymy of S. veneta with S. emerici, we exclude the occurrence of S. veneta in Croatia as an independent taxon.

2. Vegetation of silicicolous grasslands of the highlands of North-Eastern SloveniaSonja Škornik, Petras Tina, Mitja Kaligarič, 2006, original scientific article Abstract: Vegetation of the silicicolous grasslands of the highlands of North-Eastern Slovenia has been sampled with standard Braun-Blanquet procedure. All the 102 collected releves have been classified within the order Nardetalia Oberd. ex Preising 1949. The association Homogyno alpinae-Nardetum Mráz 1956 (all. Nardo-Agrostion tenuis Sillinger 1933) has been stated, inside which the typical form and the transitional forms to the heaths with Ericaceae have been distinguished. Chorology, life forms and spontaneous reforestation are discussed and nature-conservancy issue is mentioned.

3. Vegetation of tall rush saltmarshes (Juncetea maritimae) and saltmarsh scrubs (Arthrocnemetea fruticosae) on the Slovenian seacoastMitja Kaligarič, Sonja Škornik, 2007, original scientific article Abstract: Halophyte vegetation of Slovenian sedimentary seacoast was studied according to Braun-Blanquet method. 140 collected relevés were analysed by cluster analysis and five main clusters were separated. Relevés from the first, fourth and fifth clusters were further elaborated in this study. The Juncus maritimus-dominated tall rush saltmarshes of the class Juncetea maritimi were classified within two associations: Limonio-Puccinellietum represented hygrophilous stands, exposed to tide, while the association Juncetum maritimi-acuti was represented with more closed stands with higher species richness, thriving on rather drier sites. With in the saltmarsh scrubs of the class Arthrocnemetea fruticosi, 3 associations, following the declining moisture/salinity gradient were recognized: Puccinellio-Arthrocnemetum, Puccinellio-Halimionetum and Limonio-Artemisietum.
