During the last few decades vegetation changes, especially vegetation succession, became a very common phenomenon. Because many plant communities arose and are maintained by some form of agricultural activities (mowing, pasture, cutting, burning etc.), abandoning such traditional methods lead to vegetation succession and large changes in floristic composition of such, antecedent agriculturally used, areas. The island of Molat has been influenced by intensive agricultural activity during the first half of the 20th century. Afterwards depopulation began and local inhabitants decreased their agricultural activities. These demographic and agricultural changes were followed by vegetation. The largest area occupied at the beginning of the researched period was rocky grassland with 16.7 km2, while its area diminished by the end of the period, in 2006. to 0.45 km2. on the other hand maquis occupied 1.25 km2 in 1910, while in 2006 it spread to 12.2 km2. Along with mentioned changes a vegetat...

During the last few decades vegetation changes, especially vegetation succession of open habitats, became a common process on large areas in Croatia. Many plant communities arose and are maintained by some form of agricultural activities (mowing, pasture, cutting, burning etc.). Abandoning such traditional land management practice lead to vegetation succession and large changes in floristic composition of such, antecedent agriculturally used, areas. The island of Molat (22.8 km2), belongs to Zadar archipelago in central part of eastern Adriatic, has been influenced by intensive agricultural activity during the first half of the 20th century. Depopulation began during the 60-ties and local inhabitants decreased their agricultural activities. These social and economic changes affected vegetation. Recent situation was assessed during the field work between 2007 and 2010. Historical vegetation analyses were done using GIS tools based on cadastre for the whole island from the year 1910, ...
Following a change in 1997 of the boundaries of Krka National Park, comprehensive floristic field mapping of the new, North-East area of the park using basic MTB 1/64 field units was conducted during 2007 and 2008. In total, 507 plant... more
Following a change in 1997 of the boundaries of Krka National Park, comprehensive floristic field mapping of the new, North-East area of the park using basic MTB 1/64 field units was conducted during 2007 and 2008. In total, 507 plant taxa were recorded, including 92 new taxa for the park flora. The complete vascular flora of the park now consists of 1080 plant taxa, but new taxa are still expected to be discovered.

The morphometric analyses and genetic variability assessed by RAPD markers have been used to analyse relations among six Serapias taxa from Croatia (S. istriaca, S. pulae originally described as hybrid, S. ionica, S. vomeracea, S. lingua and S. cordigera). S. istriaca distributed in southern Istria and the island of Lošinj and S. pulae stenoendemic taxon distributed only in southern Istria S. ionica is endemic to the Ionian and Dalmatian islands, while the remaining taxa are more widely distributed. The obtained results shows that the endemic S. istriaca is a well characterised taxon, that S. pulae is a hybrid between S. istriaca and S. lingua and that the hybrid is morphologically and genetically more similar to S. lingua than the second parental species S. istriaca. The division into the subsections Steno-, Medio- and Platypetalae is founded based on the floral morphology while the division into the sections Serapias and Bilamellaria is not evident in the quantitative morphological and genetic analyses. Furthermore, considerable genetic resemblance between S. vomeracea and S. ionica was established.
