The paper deals with cryoplanation terraces on Kopaonik Mountain (2017m) which had been formed for the first time as a relict relief probably during the last glacial maximum (LGM) of Late Pleis-tocene. Four sites on the slopes of the southern and eastern exposure of the central part of the mountain range at the altitude between 1390 and 1910 m have been studied. Qualitative geomorphological research has dominated. Quantitative research has not been possible due to the properties of the relict formations and genetic inactivity of this relief, which is also typical for modern periglacial environments. Distinction of cryoplanation terraces on Kopaonik is important for understanding the distribution of this relict mor-phology both in Serbia and South East Europe. The research presents a contribution to one of the primary goals of the concept of cryoplanation in terms of regional distribution of cryoplanation relief.

The concept of geoheritage in general and hydrological heritage as its segment is reflected in representative examples of geodiversity - geoheritage sites. Accordingly, the issue of the identification of such extraordinary parts of the geographic mantle is one of the most important problems in this complex area of study. Assuming the universal value of water and water phenomena that result from specific characteristics, this study seeks to present and explain a theoretical pathway from an investigated water phenomenon to a concrete hydrological heritage site by stressing the importance of establishing the appropriate evaluation criteria; this pathway is necessary in order to reply the fundamental question: whether and why the observed water phenomenon does (or does not) merit the status of a hydrological heritage site. The research has resulted in universal theoretical model for the identification of hydrological heritage, which has a practical significance not only in this field, but in the identification of other types of geoheritage as well.

Despite exhibiting low velocity and limited agility, many tortoises undertake large scale movements and must overcome various obstacles, notably in populations living in hilly or rocky habitats. Although crucial, studies exploring how tortoises move in complex and irregular environments are scarce. In this context, we examined an important behavioural trait: how tortoises (Testudo hermanni) deal with step-like obstacles. In their natural habitat, individuals were positioned in a challenging situation: they were placed on a bench approximately 50cm high, and were observed over a 10-min period. We compared the behaviour of the tortoises (taking a risk to 'jump' or waiting) from two populations living in contrasted habitats: flat versus rugged (crisscrossed by cliffs and rocky steps). Individuals from the flat habitat were reluctant to jump, whereas most tortoises from the rugged habitat jumped. Immature tortoises were less willing to jump compared to larger and more experienced adults. These results suggest that challenging habitats increase boldness. In addition to fundamental findings, these results may have conservation value and assist in improving translocation strategies for endangered tortoise populations. © 2013 The Linnean Society of London.

The pollen and seeds of 3 paleoendemic resurrection species, Ramonda myconi (L.) Rchb. (Iberian Peninsula), R. nathaliae Pančić & Petrović, and R. serbica Pančić (Balkan Peninsula), as well as of natural hybrids between the 2 last species, have been analyzed using light and scanning electron microscopy. Their general structural differences, taxonomic and phylogenetic significance, pollen viability, and seed germination capacity, as well as the correlation of pollen and seed characteristics and plant ploidy levels, have been studied. The pollen grains are small (R. myconi, R. nathaliae) to medium (R. serbica) in size, ranging from 10 to 28 μm, and 3-colporate, isopolar monads with microreticulate-perforate exine. Seeds are small, 309 to 1000 μm long and 80 to 425 μm wide, elongated, with a reticulate surface and auriculate ornamentation. Micromorphologies of the pollen exine ornamentation and seed surface revealed significant differences among the 3 species. Pollen from hybrid individuals was heterogeneous in size and morphology, and the germination of their tiny seeds was very low. A strong correlation was found between pollen size, DNA content, and chromosome number. The environmental influence on pollen and seeds of 3 species and especially of the R. nathaliae population growing on serpentine is also discussed. © TÜBITAK.

Seventy-six individuals of the European mudminnow Umbra krameri from two recent populations from Serbia (Bakreni Batar and Lugomir) and one from Bosnia and Herzegovina (Gromiželj) were analysed for habitat preferences and population structure. The population from Lugomir is a newly recorded population in Serbia. Besides this new record, it is noteworthy that all three studied locations are outside the currently known species distribution range limits. © 2013 The Fisheries Society of the British Isles.

Although reptile fauna of FYR of Macedonia (FYROM) was the matter of interest since more than a century, detailed distributions of most of the species are still missing. According to published data, 32 reptile species inhabit FYROM. In this paper, detailed distribution data of reptile species in FYROM are presented. Research of herpetofauna of FYROM was conducted from 1999 until 2012 and included 393 localities. For 32 recorded reptile species, exact localities and altitudes, as well as published records are given. Analyses of the reptile diversity of the FYROM showed that the regions with the highest species diversity are: the Prespa and Ohrid Lake Region, Skopje region, Veles region and the Dojran Lake Region, with 18-21 reptile species per UTM 10 x 10 squares. These regions should be considered for the future designation of important herpetological areas at national level. Results of comparative analysis of reptile faunas from all Balkan countries showed that Macedonian fauna is the most similar with Albanian (92.537) and Bulgarian (90.909) reptile faunas. Zoogeographic analysis showed that reptile fauna of FYROM consists of eight chorotypes in total, the most dominant chorotype being the Eastern-Mediterranean with 13 species, followed by the Turano-Mediterranean with six and Southern-European with five species. Detailed distribution data of this study could be basis for future action plans, protection and conservation measures of reptiles in FYROM, and should be implemented in the national legislation and acts. In addition, this data are imperative for the Red Data Book of reptilians and designation of the Important Herpetological Areas in the country. © NwjZ, Oradea, Romania, 2014.

The Eastern Imperial Eagle (Aquila heliaca Savigny 1809) in Serbia is at the verge of extinction at the beginning of the 21st century. Only 3-5 breeding pairs have remained. The unfavorable protection status is a result of very complex negative anthropogenous factors (shooting, degradation and loss of habitat, various forms of poisoning, disturbance etc.). This species is administratively protected by Ordinance on protection of natural rarities of Serbia from 1993. The present protection measures are monitoring and survey, protection of known breeding sites and recently also the protection of important hunting areas (pastures with Sousliks) in and nearby the protected areas (NP 'Fruška Gora' and SNR 'Deliblato Sands'). The activities on education and awareness raising included printing a poster and a leaflet, publishing several science-popular articles and making a scientific documentary 'Imperial Eagle'. The measures of suppressing the negative factors (shooting, disturbance, poisoning etc) are partially completed. The future of this species is uncertain due to the continuous negative trend caused by large-scale degradation, loss and insufficient conservation of the appropriate habitat.

The goal of this paper is to provide the first complete insight into the distribution of mires in Serbia and to give an assessment of their size. For these reasons, a Serbian Mire Database and accompanied GIS Serbian mire distribution map have been developed. We estimated the distribution and total area of mires in Serbia since the last published records in 1979. Compared with the current estimation of about 3000 ha with histosols (peaty soils) in Serbia, mires were found to persist on about 1250 ha or 0.014% of the total Serbian territory, from analysing 155 mires and mire complexes. Nineteen of them are recorded and presented for the first time. Some notes on the minimum, maximum and average peat thickness as well as pH range are also discussed. A short overview on mire-related terminology and classification problems in Serbia with some suggested solutions is presented. This study also refers to the classification system for mires established by Jovan Cvijić in 1896, practically forgotten in Serbia and almost unknown outside Serbia. Finally, all relevant literature on Serbian mires is given. © 2013 Institute of Botany and Botanical Garden Jevremovac, Belgrade.

The distribution, population size and breeding density of the Egyptian Vulture Neophron percnopterus in Macedonia have been studied in two periods, 1983-1991 and 2003-2011. Results show that its population experienced decline of about 83% for the period of 30 years, counting only 22-23 pairs in 2011. The decrease has been steepest for the period 1991-2002 (-60.4%), and is mostly owing to single mass poisoning incident. Based on the overlap of the home ranges, breeding territories were grouped in clusters, and were non-randomly distributed within the clusters. Within the largest cluster, the nearest neighbor distance has significantly increased between the beginning and end of the study (from 2668.88 m to 7231.74 m in averages), and breeding density fell from 1.29 to 0.60pairs/100 km2. Breeding parameters (2006-2011) were similar to the previous studies - productivity (0.84±0.2), breeding success (0.93 ± 0.2) and the fledging rate (1.19 ± 0.16). Poisoning is considered as the primary reason for population decrease, and posed the most serious threat for the breeding population. It was also noted that some of the pairs do not return to the breeding territories, indicating possible losses along migration routes and/or in wintering regions. Urgent conservation measures are needed to safeguard the species in Macedonia, primarily by restricting the use of poison baits, which are the most important non-natural mortality factor. © NwjZ, Oradea, Romania, 2014.

Two new species of Anthroherpon belonging to the ganglbaueri species group are described from northern Montenegro: Anthroherpon sinjajevina n. sp. and Anthroherpon cecai n. sp. Based on morphological investigations of other species of this group, we elevate A. udrzali Giachino & Vailati from subspecies to species rank, and suggest the synonymy of A. brckoensis Giachino & Guorguiev with A ganglbaueri alticola Knirsch. An identification key of the ganglbaueri species group (sensu Guorguiev, 1990) is given and the distributions of species and subspecies are mapped and discussed.
