AbstrAct This paper presents six plant species rediscovered for flora of Serbia after they were considered extinct in this territory. Therefore they were included in the publication "Red Book of Flora of Serbia 1" in the category of Extinct taxon (EX). These six species are: Aconitum anthora L., Aldrovanda vesiculosa L., Chorispora tenella (Pallas) DC., Dracocephalum ruyschiana L., Juncus capitatus Weigel and Linum nodiflorum L. According to new IUCN criteria, the threat status estimation were made and the species were placed in the group of critically endangered within the territory of Serbia. New field observations of population stage and data of distribution are presented for 21 plants that were included in the category of critically endangered taxa in this publication. Population size of plants on the studied localities and new threatened status were presented for each taxon.

Here we tested plants’ ability to use iron (Fe) from the water-soluble commercial product Humiron (a complex of Fe with highly purified and solubilized humic acids extracted from leonardite) as a source of chelated Fe for both strategy 1 (e.g. cucumber) and strategy 2 (e.g. barley) plant species grown under low Fe conditions. Iron from radioactive 59 Fe-labelled Humiron can easily be acquired by strategy 1 plant species via reduction of Fe III by the inducible plasma membrane-bound reductase, similarly to the reduction of synthetic Fe III -chelates. Strategy 2 plant species can also efficiently utilize Fe from Humiron via ligand exchange between humates and phytosiderophores (PS). Moreover, the efficacy of Humiron is comparable to Fe complexed with waterextractable humic substances obtained form peat. Being easily biodegradable this product can be used as an effective Fe source for organic crop production.

Rubus laciniatus has been found as a species new for the flora of Serbia during floristic investigation in the Ibar river valley. It was found on serpentine terrains near the town of Raška (SW Serbia). This is the single known locality of the given species on the Balkan Peninsula. Data on morphology, distribution, and habitat preferences of the species are provided, and the possible pathways of its introduction in Serbia are assessed

During fi eld fl oristic investigations of serpentines in the middle part of the Ibar river valley (Kosovo’s part of the river) 915 taxa were found in the period from 2002 – 2005. Investigated area, about 50 km long, is located in the territory north of Kosovska Mitrovica all the way to the administrative border with Serbia (close to the village Donje Jarinje). Aft er this period, several new species for this area are found, during the years 2008 and 2009. Some of them are new and rare for the fl ora of Kosovo and Metohija and, at the same time, represent new localities of these species for the fl ora of Serbia. Some of the most interesting newly found species in the investigated area are: Nuphar lutea, Th ymelaea passerina, Waldsteinia geoides, Trigonella gladiata and Tremastelma palestinum.

The genus Silene (family Caryophyllaceae) comprises more than 700 species and it is one of the larger genera of the World’s flora. Studying the flora of the plain part of Kosovo and Metohija, in the village of Gracanica, on the eastern rim of the Kosovo basin (approximately 10 km to the south of Pristina), near the Gracanka stream, we identified a weed and ruderal species, Silene noctiflora . The part of the stream bank is urbanised and turned into a quay. The quay is regularly maintained implying that the banks are regularly weeded and the riverbeds are cleaned as the Typha latifolia species rapidly grows; it may be the reason why this species was not immediately detected and appropriately identified. Except for the afore mentioned locality, the species was also reported on the neglected arable fields and tilths, around the unkempt orchards, along the new tarmac road between Gracanica and Laplje Selo, on the locality called Labura. Silene noctiflora is not mentioned for the region ...

The aim of this study was to examine the possibilities of bottling the water from four sources (in total 10 springs) on Jastrebac Mountain in central Serbia. In the water samples, the following parameters were determined: • Physico-chemical parameters – temperature and solids content (total, dissolved and suspended), turbidity, pH, conductivity, hardness (as CaCO3), alkalinity (as CaCO3), oxygen concentration and saturation, concentrations of Al, Ca, Mg, Fe, F-, Cl-, and SO4 2-, inorganic nitrogen content (NH4 +, NO2 -, and NO3 -), total phosphorus and orthophosphates content (PO4 3-), and the content of organic compounds as concentrations of KMnO4 and UV extinction. • Microbiological parameters – total count of aerobic mesophilic bacteria, count of coliform bacteria, and the presence of faecal indicators (faecal coliforms, faecal streptococci, and sulphitereducing clostridia). • Biological parameters. Based on the obtained values of the examined parameters and their ratings, five s...
