AB  - UAV technologies provide a time- and cost-efficient framework for a variety of environmental monitoring domains. It also increases data resolution and provides new insights into observed objects and phenomena, especially within the difficult-to-access and complex for monitoring aquatic habitats. The objective of this study was to develop UAV-based acquisition and GIS-based image processing guidelines for aquatic macrophyte detection and monitoring in large temperate rivers. According to the European standard CEN EN -14184:2014, the assessment of aquatic macrophytes should be performed using the transect approach. Large rivers, such as the Danube, represent an exception and should be evaluated using 1km transects. Therefore, seven transects of the Middle Danube in Serbia were simultaneously surveyed using traditional field methods and novel UAV technology. UAV images were acquired using RGB and multispectral cameras carried by a fixed-wing drone. The images were processed and orthomosaics were classified using Object Based Image Analysis (OBIA), to create digital GIS maps of the river transects. During the traditional monitoring approach, the relative abundance of 22 macrophyte species was recorded along the transects. Using the UAV technology and OBIA approach eight macrophyte classes were distinguished based on dominant macrophyte taxa or plant life form traits. Aquatic macrophytes were 'almost perfectly' distinguished from the orthomosaics, achieving a high classification accuracy of 96 % / 88 % / 0.84 for RGB and 94 % / 97 % / 0.95 Producers /Users accuracy/Kappa index for the multispectral approach. Individual macrophyte classes accuracy varied between 0.5 and 1 Kappa and were generally higher for the multispectral imagery approach. Although the resolution of the taxonomic data is lower, UAV monitoring provided the necessary spatial context of macrophytes distribution and absolute area occupied by macrophytes. It also provided information on the diversity and distribution of habitats along the river. Therefore, the UAV-assisted monitoring approach described in this study can be effectively integrated into macrophyte monitoring during large river expeditions such as the JDS.

AB  - Procenjuje se da je oko 13.000 biljnih vrsta širom sveta postalo naturalizovano izvan
njihovog prirodnog areala, pri čemu područje Evrope broji skoro 6.000 naturalizovanih
alohtonih biljnih vrsta. Smatra se da tip staništa predstavlja najbolji pokazatelj nivoa
invazije na regionalnom nivou, pri čemu su riparijalna ili priobalna staništa među
onima koja se karakterišu najvišim nivoom invazije. Riparijalne zone karakteriše
mozaik različitih tipova vegetacije koji se nalaze pod snažnim pritiskom antropogenih
aktivnosti, što dodatno doprinosi invazibilnosti ovih fragilnih područja. Kao posledica
toga, riparijalna staništa postaju centri diverziteta stranih i invazivnih biljnih vrsta, a
ujedno i potencijalni izvor njihovog daljeg prodora u okolna prirodna staništa i
agroekosisteme. Imajući sve navedeno u vidu, cilj istraživanja bio je da se analizira
stepen invazije u riparijalne zone na području Srbije. Terenska istraživanja obavljena
su u periodu jul-septembar 2013-2016. godine, pri čemu je analizirano ukupno 250
lokaliteta na području Srbije. Od ukupnog broja lokaliteta, u istraživanje je uključeno
217 lokaliteta u riparijalu 39 reka (osam rečnih slivova) i 33 u riparijalu šest deonica
kanala hidrosistema Dunav-Tisa-Dunav (HS DTD). Podaci o brojnosti i pokrovnosti 26
analiziranih invazivnih biljnih vrsta beleženi su na obali reke/kanala, u okviru
transekata dužine 100 m. Kanonijsko korespodentna analiza (CCA) rađena je u
programu CANOCO 5.0. Od 26 taksona čije je prisustvo analizirano, taksoni sa
najvećim brojem nalaza su Xanthium strumarium L. subsp. italicum (Moretti) D. Löve,
Amorpha fruticosa L., Erigeron canadensis L., Robinia pseudoacacia L. i Echinochloa
crus-galli (L.) P. Beauv. Biogeografska analiza pokazala je da su u riparijalnim
područjima Srbije dominantno prisutne invazivne vrste poreklom iz Severne Amerike
(68% nalaza), praćene južnoameričkim i azijskim vrstama, koje su zastupljene sa
16%, odnosno 14% nalaza. U pogledu biološkog spektra, registrovan je najveći broj
jednogodišnjih invazivnih biljnih vrsta (terofite, 60%), dok višegodišnje drvenaste vrste
(fanerofite) predstavljaju drugu najviše zastupljenu grupu (16%). Rečni slivovi
Dunava, Južne Morave, Zapadne Morave i Timoka se ističu prisustvom invazivnih
biljnih taksona, sa 384, 131, 129 i 110 nalaza, redom, pri čemu je, veza pripadnosti
vodotoka određenom rečnom slivu i zastupljenosti pojedinačnih istraživanih taksona,
dodatno potvrđena rezultatima CCA analize. CCA analiza je ukazala da određeni
taksoni pokazuju jaču preferenciju prema rekama pojedinih rečnih slivova, npr.
Helianthus tuberosus L. je u većoj meri zastupljen u riparijalu reka sliva Zapadne
Morave, dok je Reynoutria x bohemica Chrtek & Chrtková u najvećoj meri prisutna u
riparijalnim zonama u okviru slivova Zapadne Morave i Drine. Sa druge strane, vrste
Asclepias syriaca L., Solidago gigantea Ait. i Xanthium spinosum L. su u većoj meri
zastupljene u riparijalu kanala HS DTD, u odnosu na rečne tokove. Analizom
celokupnog seta podataka o distribuciji, brojnosti i pokrovnosti analiziranih taksona,
slivovi Dunava, Zapadne Morave i Kolubare se mogu označiti kao glavni koridori
širenja većine istraživanih taksona, dok je moguće očekivati da će se u narednom
periodu, usled klimatskih promena, slivovi Save, Velike i Južne Morave takođe naći

AB  - Pistia stratiotes L. (water lettuce) is known as one of the most troublesome aquatic macrophytes, strongly affecting the environment and human activities in slowmoving and stagnant inland water systems. It was introduced into Europe in the 20th century and has since spread to 15 European countries. This paper presents data on the first record of this invasive aquatic plant in natural inland waters of Vojvodina (northern lowland part of Serbia) and discusses the possible pathways of its introduction. Field research was conducted in October and November 2017 on the Begej River in Vojvodina Province (Serbia), where populations of P. stratiotes were documented for the first time near Srpski Itebej, in close proximity (1.2 km downstream) of the Romanian border. The plant samples were collected, photographed in situ and deposited in the BUNS Herbarium. The relevant environmental data were also recorded in situ and water samples were collected for chemical analysis. This new record presents the first documented case of this invasive alien in rivers in Serbia, and expands upon the previous findings of this species in natural thermal waters of south-eastern and eastern Serbia. Taking into account the distance from the Romanian border and the fact that it has already been present in this country for several years, this introduction could be attributed to the spontaneous spreading of P. stratiotes from this neighbouring country. Nevertheless, despite this possibility, discarded aquarium plants cannot be entirely discounted as a potential source of this new introduction. Although it is hard to predict the exact consequences of this new introduction at such an early stage, bearing in mind the detrimental impacts P. stratiotes can have on the environment and excellent lateral connectivity of the Begej River with the canal and river network of Serbia, this finding highlights the need to take urgent action to control and instate regular monitoring measures, especially on the rivers and canals located close to the state borders.

Taking into account the distance from the Romanian border and the fact that it has already been present in this country for several years, this introduction could be attributed to the spontaneous spreading of P. stratiotes from this neighbouring country. Nevertheless, despite this possibility, discarded aquarium plants cannot be entirely discounted as a potential source of this new introduction. Although it is hard to predict the exact consequences of this new introduction at such an early stage, bearing in mind the detrimental impacts P. stratiotes can have on the environment and excellent lateral connectivity of the Begej River with the canal and river network of Serbia, this finding highlights the need to take urgent action to control and instate regular monitoring measures, especially on the rivers and canals located close to the state borders.",

AB  - Despite the absence of a centralized national phytocoenological database of Serbia, over 16,000 relevés of all vegetation types have been gathered and stored in the database “Phytocoenosis of Serbia” as a result of the Project “Habitats of Serbia”. However, as the data on aquatic and semiaquatic vegetation comprise only 5% of the collected relevés, the aim of this paper is to expand on this, complete the database and present the data on these vegetation types in Serbia. The work included the expansion of the existing database with the addition of relevant sources, their digitalization, using Flora and Turboveg programs, and their subsequent georeferencing, using OziExplorer and DIVAGIS softwares. Consequently, the phytocoenological database on aquatic and semiaquatic vegetation in Serbia now stores 1,720 relevés from 243 phytocoenological tables, collected and published by 24 authors during the period of 70 years (1940–2010), with the majority of the relevés collected over the last decade (56.40%). Phragmito-Magno-Caricetea Klika in Klika et Novák 1941 (Syn: Phragmitetea communis R. Tx. et Prsg. 1942), Potametea Klika in Klika et Novák 1941 (Syn: Potametea R. Tx. et Preising 1942) and Lemnetea de Bolós et Masclans 1955 (Syn: Lemnetea minoris W. Koch et R. Tx. 1955) have proven to be the most represented classes, while Scirpo-Phragmitetum W. Koch 1926 (nomen ambiguum) and Salvinio natantis-Spirodeletum polyrrhizae Slavnić 1956 are associations with the highest number of relevés in the database. Accordingly, the most common species (>500 relevés) are Ceratophyllum demersum L. subsp. demersum, Lemna minor L. and Spirodela polyrhiza (L.) Schleiden.
