Renewable energy sources (RES) have the possibility to regenerate in a shorter time interval than the non-renewable energy sources and that is why they have always been the subject of interest, ...especially in the last decades. The Republic of Serbia has RES in the form of solar, wind, the power of water flow, geothermal heat, and biomass. The scientific research conducted in July 2016 in Temska village (City of Pirot) aimed to assess inhabitants’ attitudes and awareness of using RES. By interviewing 167 respondents, it is concluded that inhabitants do not have sufficient knowledge of quality and information on RES. Mostly, they are familiar with all terms: hydropower, solar, wind and geothermal energy (over 80%), and the term of biomass energy as well (70.7%). There is an extremely high level of misinformation about the RES subventions that are provided by the Government of the Republic of Serbia (up to 85.6% of respondents are not informed). These subventions are published in the Regulation on incentive measures for the production of electricity from RES and are based on the Feed-in Tariff system that is defined as non-refundable financial assistance from the state. A small number of respondents use RES, but a considerable number (21.6% ‘yes’ and 47.3% ‘maybe’) that does not use RES is interested, or already planning to use it in the future.
A redescription of the genus Antrosedes Reitter, 1912 is given. An identification key for both species of the genus, as well as data on their distribution is provided.
Mt. Stara Planina is located in the eastern part of the Republic of Serbia and represents the westernmost part of the large mountain massif of the Balkans. Both endogenous and exogenous forces ...created interesting geomorphological and hydrological features for geotourism development in this area. This article proposes a preliminary list of geomorphological and hydrological sites and analyses them to reveal which geosite possesses geotourism potential. This research was carried out by applying the modified geosite assessment model. In this article, ten geosites were singled out based on the degree of their attractiveness for geotourism development. The results reveal information about the key fields of improvement for each evaluated geosite, and identify which areas require more attention and better management in the upcoming period for Mt. Stara Planina to become a well-known geotourism destination that would attract a large number of tourists in the future.
This study aimed to investigate the prevalence, intensity and risk factors (age and gender) promoting the intestinal helminthic infections of the Domestic mountain ponies and Balkan donkeys in ...Serbia.
Prevalence, intensity and risk factors influencing helminth infection in horses (n=39) and donkeys (n=18) at the site of Nature Park Stara Planina, were studied from May to Sep 2015. The presence of one or several gastrointestinal helminth species was confirmed by faecal flotation in 97.43% of horses and 88.88% of donkeys included in the monitoring. The identified helminth species were

The prevalence of parasitic helminths identified in donkeys was the following:

in 55.55%, 38.89%, 27.78%, 22.22% and 22.22% of donkeys, respectively. Moreover, the mean faecal egg count was higher in donkeys (369.9 EPG - egg per gram) than in horses (250.2 EPG). The association between the age and the mean EPG was significant (
<0.05) in both equine species.
The results of the investigation provided basic information that can be helpful for planning strategic control of nematode infection in equine population in Nature Reserves in Serbia.
Thufur (earth hummocks) are small periglacial landforms typical for subpolar
latitudes, as well as for the high alpine areas at lower latitudes. Their
presence in the mountains of the Balkan ...Peninsula was spotted during the
mid-20th century. In this paper we analyze morphometry and morphology of
thufur in the context of physio-geographical conditions for their formation.
The main aims are to inventorize the thufur in the study area and to
determine the physio-geographical factors which enabled their formation at
non-zonal elevations. Statistical analysis was performed on the sample of
305 thufur mapped in the field, measuring their circumference, height, and
delineating their areas. Classification of the results revealed
morphological varieties in terms of horizontal and vertical development. The
elevation of the sampling location Ponor is 1,410 m a.s.l., which is
considerably lower than the zonal periglaciation in Serbia, at approx. 1,900
m. Therefore, the role of relief as a climate modifier is analyzed in the
context of conditions for the azonal development of periglaciation process.
Topographical conditions for thufur formation were analyzed through slope
inclinations and vertical dissection, determined using the Digital Elevation
Model over Europe with 25 m resolution.
