To mark the great jubilee of the Natural History Museum in Belgrade – 125 years since its founding – members of the Editorial Board has decided to publish, in the upcoming editions of the Bulletin, biographies of those who contributed the most to the establishment of the Museum and its initial collections. In this way, we would like to thank our predecessors for their immense work and great driving energy, not just in laying the foundations but also in ensuring the continuity of the work of the Museum. At the same time, we also want to acquaint the wider scientific and professional public, as well as younger generations of naturalists, with the important persons from the Museum’s rich historiography.
Keywords: Petar Pavlović, founder of the Natural History Museum, life and work
In remembrance of the 100th anniversary of the arrival of geologist and university professor Vladimir Laskarev in Serbia and the beginning of scientific research of loess sections in Zemun, the author’s intention is to point out the importance of knowledge of geological history and tradition, but also the actual nature of the study of loess-paleosol deposits. This is especially important at the time when numerous projects and teams of researchers in Serbia and the world are dealing with this issue. Today as well as in Laskarev’s time, they all have the same task: to qualitatively and quantitatively explain natural processes and their consequences, and to point out significant oscillations in temperature and climatic fluctuations during the Pleistocene.
Key words: Laskarev, Pleistocene, Climate change, Loess-paleosol, Zemun

At the Neolithic settlement „Pločnik“ near Prokuplje in Serbia, the electrical imaging method (ERT) was deployed. At the sounding site S-3, 1D electrical
survey revealed a low resistivity layer with a thickness of 0.8 meters and a resistivity of about 30 Ωm. A sharp and steep boundary divides the high resistivity medium and the low resistivity medium, according to the 2D electrical survey. The resolution of the ERT method was tested using 3D forward and inverse modeling to see whether it could distinguish the high resistivity pit from the surrounding high resistivity gravel.
Key words: Electrical imaging (ERT), Neolithic settlement “Pločnik”, Forward modelling, Inverse modelling.

The aim of this study was determining and comparing diatom diversity and dominant taxa in 4 seasons from the Crnica River. A total of 170 diatom taxa, 24 among them as dominant ones were recorded. The highest diversity expressed in number of taxa was observed in the spring (139) and the lowest in the autumn season (94). The most of 45 the best fitted taxa on the CCA ordination diagram are recorded in more than two seasons, often in all four seasons. One group of taxa (e.g. Hanaea arcus, Meridion constrictum, Navicula gregaria, N. lanceolata) was characteristic only for spring and other for winter season (e.g. Gomphonema innocens, G. lagenula, Stauroneis phoenicenteron, Nitzschia oligotraphenta). There were no taxa exclusively recorded only in summer and autumn.
Key words: diatom community, seasonality, Crnica River

The paper proposes eight new nomenclatural combinations and indicates two new synonyms. There are 11 taxa (species and subspecies) of the vascular flora that are new for the flora of Serbia (of which nine are autochthonous and two allochthonous plants). Two autochthonous species were confirmed for the flora of Serbia. Six plant taxa are a novelty for proper Serbia, Vojvodina, or Kosovo and Metohija. There are eight taxa whose presence in Serbia or in its territorial units has been refuted.
