The ageing of population in Kanjiza municipality
The aging of population in Vojvodina Province is one of the main political, national and economical issues. This paper presents the demographic situation in municipality of Kanjiza, researching the age structure. The aging is one of the most important demographic characteristics, which analyses the stage of development of a certain population. The consequence of low birthrate and emigrations in municipality of Kanjiza during the last 30- 40 years, is that the population in 1971. was in fourth stage of demographic development. The age structure in this paper is presented through the ageing of population, ageing index, age ratio, age group up to 20 year (young population) and age groups over 60 (old population), part of fertile and active population.
Pasture vegetation near the village of Iđoš
A pasture on the solonchakic solonetz soil in the vicinity of the village of
Iđoš (Banat, Serbia) was found to harbor 137 plant taxa (129 species, 7
subspecies and 1 variety). The plant cover they formed was specific from the
ecological, phytogeographical and phytocoenological points of view. The
specific ecological feature of the surveyed plant cover was that 47 or 34.31%
of the recorded taxa were rated with the ecological index S+ due to their
ability to grow in saline soil. The specific phytogeographical feature of the
surveyed plant cover was the presence of two Pannonian endemics, Plantago
schwarzenbergiana Schur and Statice gmelini subsp. hungaricum (Klokov) Soó,
and two subendemics, Puccinellia limosa Holmb. and Roripa kerneri Menyh. The
specific phytocoenological feature of the surveyed plant cover was the
presence of two phytocoenoses from the class Phragmitetea Tx. et Prsg. 1942
(ass. Scirpo-Phragmitetum medioeuropaeum and ass. Bolboschoenetum maritimi
continentale), one phytocoenose from the class Molinio- Arrhenatheretea
Tx.1937 p.p., Br.-Bl. et Tx. 1943 p.p. (ass. Trifolio-Lolietum perennis) and
ten phytocoenoses from the class Festuco-Puccinellietea Soó 1968 (ass.
Puccinellietum limosae, ass. Pholiuro-Plantaginetum tenuiflorae, ass.
Hordeetum histricis, ass. Agrostio-Alopecuretum pratensis, ass.
Agrostio-Beckmannietum, ass. Halo-Agropyretum repentis, ass.
Poeto-Alopecuretum pratensis halophyticum, ass. Artemisio-Festucetum
pseudovinae, ass. Trifolio-Festucetum pseudovinae and ass.
Achilleo-Festucetum pseudovinae). The presence of 34.31% of taxa rated with
the ecological index S+, the presence of two Pannonian and two sub-Pannonian
floristic elements and the predominance of stands from the class
Festuco-Puccinellietea Soó 1968 led us to conclusion that the pasture near
the village of Iđoš (Banat, Serbia) is a part of the halobiome of the
Pannonian Plain. [Projekat Ministarstva nauke Republike Srbije, br. TR31016:

Vegetation of the classes Hydrochari-Lemnetea Oberd. 1967 and Potametea Tx. et Prsg. 1942 in the Jegrička watercourse (The province of Vojvodina, Serbia)
The Jegrička, once a natural watercourse traversing the southwestern part of the Bačka region, has been turned into a canal, which became part of the main canal network of the hydro-system Danube-Tisza-Danube (Hs DTD). In its turn, the Hs DTD is part of the European waterway linking the North Sea to the Black Sea, i.e., part of the navigable Rhine-Main-Danube Canal. The watercourse is 65.4 km long and it is divided into three levels. The presence of the regulated and the nonregulated sections of the canal, frequent and abrupt changes in water level in the individual sections, different depths and surface water widths of the various sections and the fishpond constructed in the lower section cause considerable vegetation diversity. The vegetation comprises aquatic associations of the classes Hydrochari-Lemnetea Oberd. 1967 and Potametea Tx. et Prsg. 1942. The class Hydrochari-Lemnetea Oberd. 1967 includes the following phytocoenoses: Salvinio-Spirodeletum polyrrhizae Slavnić 1956, Ceratophylletum demersi (Soó 27) Hild. 1956, Lemno-Utricularietum vulgaris Soó 1928 and Hydrocharidetum morsus-ranae Van Langendonck 1935. The class Potametea Tx. et Prsg. 1942 includes the associations Myriophyllo-Potametum Soó 1934, Najadetum marine Fukarek 1961, Nymphaeetum albae Vollmar 1947, Nymphoidetum peltate (Allorge 1922) Oberd. et Müller 1960 and Trapetum natantis Müller et Görs 1960
Tourists’ Motivation in Wetland Destinations: Gornje Podunavlje Special Nature Reserve Case Study (Mura-Drava-Danube Transboundary Biosphere Reserve)
The main objectives of this research were twofold: firstly, to evaluate tourists’ perception of Gornje Podunavlje Special Nature Reserve, one of the four significant protected areas within the Serbian part of Mura-Drava-Danube Biosphere Reserve, and secondly, to identify the motivations behind tourists’ visits to wetlands and their overall satisfaction with the visits. In addition, this study was also focused on the relationships between aforementioned constructs and tourists’ socio-demographic characteristics and visit characteristics. Finally, this study attempts to address the relationships between tourists’ motives for their visit, their image perception and satisfaction. The research findings showed that each of the three remaining factors had significant relationships with Satisfaction and experience. The research was conducted in the form of the survey in the period between May 2020 and April 2022 on the sample of 216 visitors. The research findings showed that each of three remaining factors had significant relationships with Satisfaction and experience. Relationships are also found between identified improvement requirements, Motivation for spending time particularly in wetlands, and perceived biodiversity image. Finally, there are significant relationships between duration of the visit with Satisfaction and experience and Motivation for spending time in nature and future behavior. Practical implications of the research results might be beneficial for managers of wetland destinations, in order to improve the offer in line with tourists’ preferences
Entrepreneurial Intention of Students (Managers in Training): Personal and Family Characteristics
To increase the entrepreneurial intention, it is necessary to understand the main drivers that are driving students, as carriers of future economic development, towards starting a personal business venture. With regards to that, the main aim of this research was to analyze the entrepreneurial intention among students (managers in training) in the field of tourism and hospitality management. Particular attention was paid to the influence of their socio-demographic characteristics, as well as their parents on entrepreneurial intention. The research was conducted in survey form on a sample of 310 students in Serbia in 2020. The main findings indicated that entrepreneurial intention is higher among the male students, as well as among those students whose parents are entrepreneurs or whose fathers are retired. Besides theoretical contribution, the research results might contribute to scientific and research organizations and institutions in providing the guidelines for forming study programs that will raise the students’ entrepreneurial intention

Aquatic and Wetland Vegetation Along the Sava River
Diverse hydrological, climate, and soil conditions along the Sava River caused significant diversification of vegetation. Therefore, the objective of this chapter is to integrate and present all the available data on variability of the aquatic and riparian plant communities along the Sava River and its main tributaries as well as to identify the environmental factors, which are related to the distribution of different vegetation types. Special attention has been also paid on the detection of threats for rare and endangered plant species and fragile wetland ecosystems along the Sava River. Based on data review, syntaxonomic revision of aquatic and riparian vegetation based on common, pan-European databank is required. Ecological studies that involve inventory, monitoring, modeling, and prediction of changes in populations, ecological communities, and ecosystems require both georeferenced databases and computational tools for application of statistical methods.Milačič R, Ščančar J, Paunović M, editors.
