AB  - The effect of anesthesia/euthanasia with ethyl 3-aminobenzoate methanesulfonate (MS-222) on the oxidative status of Hyla arborea tadpoles was examined to determine whether the use of the anesthetic can confound the experimental results of the oxidative stress-based investigation. The experiment was conducted on two groups of tadpoles reared at different temperatures to produce differences in antioxidant capacity between the groups. After development at different temperatures (20 °C and 25 °C), the animals were exposed to different concentrations of MS-222 (0, 0.1, 1, and 5 g/L) for 15 min. The higher temperature decreased catalase activity, glutathione and protein carbonyl levels and increased glutathione reductase activity. The glutathione level and glutathione/thiol-related parameters were significantly changed after MS-222 exposure. However, individuals from the different temperature groups responded differently to the tested anesthetic, pointing to the possible influence of the initial levels of antioxidant capacity. The analysis of the interaction between the factors (temperature and MS-222) confirmed that the anesthetic can confound the results regarding the effects of temperature on the oxidative status parameters. The concentration of 0.1 g/L MS-222 had the lowest influence on the alterations in oxidative status and the results of the effect of temperature. A brief review of the current literature on the use of MS-222 in tadpoles made clear the absence of precise information on anesthetic concentration and exposure time. Similar studies should be repeated and extended to other amphibian species and other factors of interest to provide better guidance on tadpole anesthesia/euthanasia for future experiments that consider oxidative status parameters.

AB  - The unken reflex (UR) is a deimatic behaviour in certain toad species, such as the European firebellied toad. These toads are cryptically coloured on their backs; however, when they feel threatened, they arch their backs and raise their limbs, revealing the brightly coloured ventral side of the body. This sudden appearance of bright colour has a startling effect and warns potential predators that the toad is poisonous. As an antipredator behaviour, UR should be under selection and adapt to different types of predators/predation pressure. We examined the occurrence and duration of UR in 106 individuals from three populations of the European fire-bellied toad (Bombina bombina). We gently tapped the toads’ heads (5 times) and grabbed them with rubber forceps to entice them to perform UR. We noted the occurrence of UR, whether the toads entered UR by tapping or grabbing and the duration of UR. We observed no significant differences in the occurrence of UR between the localities, but there was a significant difference in the duration of UR between localities. In the locality where UR lasted the longest, toads entered UR more often by grabbing than by tapping. UR was longest in the locality in an urban environment where there are far fewer predators (except cats and dogs) than at the other two localities (natural wetlands) where natural predators are abundant (snakes, water birds and small mammals). Our results may indicate potential local adaptations to different predators/predation pressures and deserve further attention. Future studies of UR should also include features such as belly colour, pattern, and contrast, as these features are also likely crucial to the occurrence and duration of deimatic displays in these toads.

AB  - When captured by a predator, the prey’s options for escape decrease dramatically; however, some species, such as dice snakes, display a wide variety of behaviours in order to escape. We explored how factors such as locality, body temperature, body size, sex, reproductive status (i.e. gravid vs. non-gravid), presence and state of injuries, and the presence of food affect the occurrence of behavioural displays in a capture situation within and among four free-ranging populations of dice snakes, Natrix tessellata (Colubridae). Our study shows that dice snakes regularly hiss, discharge their cloacal glands, and coat themselves in musk when captured, while other behaviours were displayed only occasionally. Our study corroborates previous findings of local differentiation in snake behaviour, especially the case of supposed Batesian mimicry in dice snakes. In three of four localities where the dice snake lives in proximity or in sympatry with nose-horned vipers, they display fake striking, with additional head flattening as opposed to the viper-free locality. Larger snakes exhibit a wider array of antipredator behaviours, which commonly include musking and hissing. Expectedly, warmer snakes were more likely to display vigorous antipredator
behaviours such as struggling and striking. Injured snakes (a possible measure of a previous exposure to predation) displayed fewer behaviours and musked and hissed less. We call into question the analysis of isolated antipredator behavioural displays, and encourage using entire behavioural sequences in order to understand the complexity of antipredator behaviour.

We call into question the analysis of isolated antipredator behavioural displays, and encourage using entire behavioural sequences in order to understand the complexity of antipredator behaviour.",

AB  - Alpine habitats are exposed to increasing anthropogenic pressure and climate change. The negative impacts can lead to chronic stress that can affect the survival and reproductive success of individuals and even lead to population extinction. In this study, we analyse different morphological and ecological traits and indices of abiotic and biotic stressors (such as head size and shape, fluctuating asymmetry, body condition index, tail autotomy, and population abundance) in alpine and subalpine populations of two lacertid species (Zootoca vivipara and Lacerta agilis) from Serbia and North Macedonia. These lizards live under different conditions: allotopy/syntopy, different anthropogenic pressure, and different levels of habitat protection. We found differences between syntopic and allotopic populations in pileus size, body condition index (in both species), pileus shape, fluctuating asymmetry (in L. agilis), and abundance (in Z. vivipara). Differences between populations under anthropogenic pressure and populations without it were observed in pileus shape, body condition index (in both species), pileus size, fluctuating asymmetry, tail autotomy and abundance (in L. agilis). On the basis of our results, it is necessary to include other stress indicators in addition to fluctuating asymmetry to quickly observe and quantify the negative effects of threat factors and apply protective measures.

AB  - The sand lizard (Lacerta agilis), which occupies a large part of temperate Eurasia and includes several morphologically and genetically distinct lineages, is a model species for life-history studies. Yet, for major parts of the species range, basic data on female reproductive traits are lacking. Here we present the first data on female reproductive traits of Lacerta agilis bosnica, a poorly studied lineage inhabiting montane areas of the Balkan Peninsula. Ten females caught in mid-June 2017 on Mt. Maljen (950 m a.s.l.) in western Serbia were monitored and examined in the lab, as well as their eggs and hatchlings. We additionally examined the state and number of oocytes in 31 females from scientific collections. Mean clutch size is quite high (8.0 ± 0.4 eggs) in relation to small mean snout-vent length of gravid females (74 ± 1 mm), mean relative clutch mass is relatively low (0.37 ± 0.02), and egg incubation period (51 ± 1 days at 24-26 °C) is rather long for L. agilis. While mean values of the above traits are within the variation range found across conspecific populations studied thus far, mean values for egg size (mass, 0.42 ± 0.02 g; length, 11.8 ± 0.2 mm; width, 7.7± 0.1 mm) and hatchling size (mass, 0.47 ± 0.03 g; SVL, 25.0 ± 0.5 mm; tail length, 30.4 ± 1.6 mm) are clearly smaller than in all previously studied populations of this species.

AB  - Insular populations offer excellent opportunities to study the factors that influence phenotypes. We observed island dwarfism in a widespread snake, the nose-horned viper (Vipera ammodytes). Island vipers were ~20% smaller than mainland individuals. They also produced fewer and smaller offspring. In snakes, food availability has a positive influence on body size, fecundity and offspring size. Consequently, low energy intake is a plausible explanation for insular dwarfism. The diet of island vipers was principally represented by lizards and centipedes, whereas the most profitable prey items (e.g. rodents) were regularly found in the stomach of mainland vipers. Furthermore, the proportion of individuals captured with a full stomach and good body condition were lower on the island compared with the mainland. Thus, island vipers were likely to be experiencing permanent energy restriction, with cascading effects on adult body size and reproductive output. Large prey promotes high relative jaw length in snakes. Island
vipers displayed smaller relative jaw length compared with mainland populations, suggesting that plasticity played a role in insular dwarfism. But the difference in relative tail length between island and mainland populations, a trait not subjected to food-induced plasticity, indicates local adaptation. Both plasticity and adaptation might influence the phenotype of island vipers.

AB  - Amphibians and reptiles are the most threatened vertebrates by traffic, especially near
ponds and wetlands. The main aim of this study was to examine seasonal and spatial patterns of
amphibian and reptile road mortality in Special Nature Reserve “Obedska bara” (Serbia). We chose a
road section of 4.2 km near the largest wetland in Serbia, with two different habitat types (forest-pond
and agricultural area-pond). During 2018 (32 fieldwork days) and 2019–2020 (three control fieldwork
days), we found 20,457 and 2231 road-killed animals, respectively. We recorded nine amphibian
and eight reptile species. Amphibians (93%) were more vulnerable to traffic than reptiles (7%). The
number of killed amphibians and reptiles varied between the seasons. Generally, amphibian roadkill
was most frequent during the summer, whereas reptile roadkill was most frequent in spring and at
the end of the summer. Furthermore, different roadkill patterns were observed during the examined
months. In addition, we found that habitat type significantly affects the vulnerability of animals
towards the roads. For both amphibians and reptiles, there were significant aggregations of roadkill,
and most hotspots were located at the forest pond habitat type where mitigation measures must be
applied (construction of tunnels and fences).

Due to the Mediterranean influence that is spreading across the North Macedonia to the north, some Mediterranean Reptile species have been recorded in Serbia, but there is a possibility that there are still unregistered ones. Concerning the importance of this part of Serbia, intensive faunistic research was done, which resulted in the discovery of L. trilineata, a new species for the herpetofauna of Serbia, in several localities. At each of explored localities, we found only one or few individuals of L. trilineata.

with limited distribution: Hyla orientalis and Pelobates balcanicus. Also, one
species (Triturus ivanbureshi) has restricted distribution, while one (Bombina
bombina) is rare. Four reptile species have limited distributions and six are rare in
these regions. The presence of hybrid zones and the influence of the Mediterranean
climate make southern and south-eastern Serbia areas of great importance and the
target for future ecological and conservation studies in Serbia.

распрострањењем: Hyla orientalis и Pelobates balcanicus. Такође, једна
врста репатих водоземца (Triturus ivanbureshi) има ограничено распрострањење, док је Bombina bombina веома ретка. Четири врсте
гмизаваца су са ограниченом дистрибуцијом, а још шест су веома
ретке у ова два биогеографска региона.
Од укупно 38 врста водоземаца и гмизаваца потврђених у регионима јужне и југоисточне Србије, шест је рањиво/готово угрожено према
критеријумима IUCN-а, осам су на анексу II Директиве о стаништима,

AB  - In this paper, the updated checklist of Serbian amphibians and reptiles is
presented. The updated checklist of Serbian amphibians and reptiles was compiled
from the literature on distribution, taxonomy and phylogeny. The checklist
contains 48 autochthonous and two introduced species. Five species underwent
taxonomic revisions (Triturus ivanbureschi, T. macedonicus, Pelobates balcanicus,
Bufotes viridis and Mediodactylus kotschyi). Two species were added after recent
taxonomic splits of species’ complexes (Hyla orientalis and Anguis colchica).
Presence of new (Lacerta trilineata) and introduced species (Hemidactylus turcicus)
was confirmed during recent fieldwork. There are at least eight more species
that can potentially be present in Serbia. The national protection legislative should
be updated according to the current checklist.
AB  - У овом раду приказујемо ажурирану листу фауне водоземаца и
гмизаваца у Србији. Листа је састављена на основу литературе о
дистрибуцији, таксономији и филогенији водоземаца и гмизаваца који
припадају нашој фауни. Садржи 48 врста аутохтоних за Републику
Србију као и две интродуковане врсте за које је потврђено да се на
територији Србије размножавају и успостављају популације. Пет
врста на овој листи су недавно прошле кроз таксономску ревизију
(Triturus ivanbureschi, T. macedonicus, Pelobates balcanicus, Bufotes
viridis и Mediodactylus kotschyi), а две врсте су придодате након
скорашњег таксономског раздвајања комплекса врста (Hyla orientalis и
Anguis colchica). Најновија теренска истраживања су потврдила при-
суство једне нове (Lacerta trilineata) и једне интродуковане врсте
(Hemidactylus turcicus). Потенцијално је на територији Репубике Срби-
је присутно још најмање осам врста водоземаца и гмизаваца, пре свега
у пограничним областима. Од 48 врста аутохтоних за Републику
Србију, седам су рањиве/готово угрожене на међународном нивоу,
према критеријумима IUCN, три су у прилозима CITES-а, 39 се налазе
на анексима Директиве о стаништима (Habitat Directive), а све су на
прилозима Бернске конвенције. У току је процена конзервационог
статуса свих врста на националном нивоу, на основу чега ће бити
предложена нова легислатива.
Са 48 врста, Србија се може сматрати за богату биолошком
разноврсношћу водоземаца и гмизаваца па чак и центром диверзитета
појединих таксона – пре свега великих мрмољака и других комплекса
врста (Hyla, Pelophylax, Anguis). Даља истраживања батрахо- и херпе-
тофауне требало би концентрисати на контактне/хибридне зоне
комплекса врста и пограничне области наше земље.

AB  - We present the updated distribution data of the Hyla arborea species complex
in Serbia. Hyla arborea inhabits all biogeographic regions, while Hyla orientalis
inhabits only the easternmost parts of north-eastern, eastern and south-eastern
Serbia. Potential hybrid zone encompasses parts of central and southern Serbia
from the Đerdap gorge, over Niš to Bosilegrad. Since the taxonomic separation between the tree frog taxa was not yet recognized in national nomenclature, we
propose the official Serbian names. The species H. arborea will keep the standard
Serbian name “Gatalinka”, while for the species H. orientalis we propose the name
“Istočna gatalinka”.
AB  - У овом раду, приказујемо ажуриране податке о дистрибуцији
комплекса врста Hyla arborea у Србији. Подаци се састоје од налаза
објављених у литератури или на Интернету, заједно са претходно
необјављеним теренским подацима. Од ове две врсте, највећи део
територије Србије, укључујући све биогеографске регионе, насељава
H. arborea. Hyla orientalis, са друге стране, насељава само крајње
источне делове североисточне, источне и југоисточне Србије, са
потенцијалном хибридном зоном која такође обухвата делове централ-
не и јужне Србије. Дистрибуција H. arborea је густа у панонским
деловима Србије, конкретно у плавним зонама река Дунав, Сава и
Тиса, док је дистрибуција више раштркана у перипанонским и
планинско-котлинским деловима Србије. Hyla orientalis насељава
искључиво најисточније делове планинско-котлинског региона, где је
повезана са воденим системима који припадају Балканском планин-
ском венцу, док Карпатски и Родопски масиви представљају северо-
источну и југоисточну границу дистрибуције, респективно. За хибрид-
ну зону се претпоставља да обухвата оквирно 30 км широк коридор
који се протеже од Ђердапске клисуре, преко Ниша до Босилеграда,
али додатно узорковање ће морати да се изврши како би се ово
потврдило.

AB  - Studies of body condition in snakes are generally lacking and were only done on a few species and with limited sample sizes. Additionally, almost no studies considered how different factors affect body condition. We used a large dataset amassed over a 15 year-long ecological study to make a preliminary screening of body condition index (BCI) variation in a metapopulation of dice snakes (Natrix tessellata) in the region of Lake Prespa. We considered how factors such as sex, food, colour morph, locality and time affect BCI. We demonstrate a positive effect of food (relatively less in males), and lower BCI in females. Importantly, there is a strong seasonal effect, summer months having a positive effect as opposed to spring. The results of our study raise important considerations for future studies on snake BCI, but also conservation of freshwater ecosystems.

AB  - Snake venom is a complex secretion of proteins, peptides and small compounds. Being closely related to feeding, this important ecological trait is highly variable. The resulting variations are notably characterised by the abundance of different toxins, both at inter-and intraspecific levels. Here we addressed variation in venom composition of two populations of Vipera ammodytes from North Macedonia. One population inhabits Golem Grad Island (Prespa Lake) where vipers feed mainly on ectotherms, and the other is from the nearby mainland (Konjsko village) where endotherms are included in the diet. Using the bottom-up protocol for venom proteome analysis, five pools (insular juveniles, subadults, adult males and adult females, and adults from the mainland) were analysed, from a total of 50 individuals (46 from the island and four from the mainland). The venom profiles of the insular and mainland population differed, likely reflecting prey divergence between the sites. At the population level, in Golem Grad, venom composition showed an ontogenetic shift in the relative occurrence of different toxin families. This change is probably due to the shift in the diet; juveniles feed mainly on centipedes and small lizards, while adults essentially consume lizards. On the contrary, there was negligible variation in venom profiles of island adult males and females, likely due to their similar diet. Our results reveal fine-tuned and rapid (ontogenetic) parallel shifts in diet and venom composition and highlight the need to consider species' ecology in any causal model of venom variability.

AB  - Sexual dimorphism in body size has been observed in several snake species. Natural and sexual selections and their interaction lead to differences in morphological traits between males and females. During the ontogeny, various changes in body parts can occur between the sexes. Different body sizes can reflect different behaviours and reduce interpopulation competition for resources. We examined sexual dimorphism in Caspian Whip Snake (Dolichophis caspius). We analysed the suburban population in Belgrade (Serbia). The sample consists of 72 females and 66 males of three age categories (juveniles < 40 cm of SVL, subadults from 40.1 to 70 cm of SVL and adults > 70.1 cm of SVL). We analysed eight morphometric parameters (standard body length - SVL, tail length - TL, jaw length - JL, cranial length - CL, postparietal length - PPS, head width - HW, mouth length - ML and mouth width - MW) and body weight - BM. Descriptive statistics showed that the values of all analysed traits were higher in adult males (the mean values of total body length were 137 and 117 cm for adult males and females, respectively), and ANOVA showed that these differences were statistically significant. The same analyses showed significant sexual dimorphism in the relationship between body length and tail length (SVL/TL). After correction for body size (ANCOVA with SVL as a covariate), sexual dimorphism was not expressed in any of the analyzed traits. In juvenile and subadult individuals, sexual dimorphism is not pronounced. The observed differences in morphological traits may be related to distinct features of life history, so our further research will consider the differences between the sexes in the growth rate, the size at which they reach sexual maturity, diet, predation, and activity patterns.

AB  - Golem Grad island, better known as “Snake Island” due to the large population of dice snakes
(Natrix tessellata) is a strictly protected area within National Park Galičica (North Macedonia). From
2008, the snakes’ tale started slowly unravelling, thanks to the start of mark-recapture monitoring.
More than 6.000 snakes were marked during >15 years. Opportunistic dissections provided information
about fecundity and body condition. Three distinct colour morphs coexist: ‘green back with dark spots’
is the most common, but uniformly green and melanistic individuals are not rare either. Furthermore,
this population exhibits gigantism, possibly due to the abundance of food: the largest island male
and female measured 113cm and 129cm, respectively, in contrast to maximal body sizes from other
populations reported in literature: 95cm and 122.5cm. Worryingly, this island population faces serious
threats, especially fish poaching. Hundreds of snakes meet their untimely fate tangled and ultimately
drowned in fishing nets, or even persecuted, while small individuals are crushed by the rocks they hide
under by wandering tourists. Despite continuous conservation efforts, this snake population is rapidly
declining, particularly since 2011 when poaching pressure increased. More recently, additional dice
snake population surveys were launched in Prespa, in Konjsko village (MK) and on Mal Grad Island (AL).
The conservation status differs among the three localities. According to IUCN Red Lists, the dice snake
is considered as Near Threatened (NT) in North Macedonia, while in Albania it is still classified as Not
Evaluated (NE; however in the new, updated list of 2019 (still unpublished) is has been evaluated as
Least Concern (LC)). We plan to use genetics and recapture analyses to assess the genetic structure and
the degree of (possible) connectivity among sites. This information will be especially useful in order to
understand how viable Prespa Lake’s dice snake population(s) are, despite the various pressures they
face. Efficient conservation actions rely on such insight, while a species conservation action plan at the
transboundary level is required.

AB  - Prey animals have developed a wide array of antipredator behaviours to confront, dissuade or escape a predator. Death feigning (DF), where prey animals get in a tonic immobile state and resemble dead animal, is a sort of a last-ditch attempt to escape consumption. Even if this behaviour works, it is vitally important that the prey chooses the right time to escape: a quick decision may attract the predators' attention, while waiting too long might prolong exposure. In the field, we measured both the occurrence and the duration of DF in three distinct colour morphs of dice snakes; the most common dice morph, uniformly green, and melanistic individuals. We sampled only adult individuals and considered factors such as sex, size, body temperature, injuries, and presence of food, gravidity as well as absolute crawling speeds on the occurrence and duration of DF. Our results suggest that females DF more often than males and that gravid females DF the least often. Snakes that crawled faster were less likely to DF, but interestingly, gravid females that crawled faster were more likely to DF. Diced and green gravid snakes spent far less time in DF than nongravid individuals, while in melanistic snakes gravidity did not affect DF duration. These differences are especially pronounced in the uniformly green snakes. Additionally, colder, bigger and faster snakes DF for longer intervals. Larger snakes cannot be immediately consumed and thus can afford to try a risky strategy such as DF, which is supposedly used as a hard reset in a predator-prey interaction. Gravidity undoubtedly imposes significant constraints on snakes and probably limits escape options and makes DF too risky. However, melanism can offer certain advantages to gravid individuals, notably thermal benefits and in turn a higher metabolic rate and locomotor capacity which can prove beneficial in a DF situation.

AB  - The establishment of ecological networks (including Natura 2000) is one of the priorities in the conservation of important species and habitats in the Republic of Serbia. During the last three years (2020-2022), we conducted field research on amphibian and reptile species listed in the Annexes II & IV of the Habitat Directive. The main goals were to obtain data about precise geographic distribution, estimate population statuses and conservation threats, as well as to propose conservation measures for the studied populations and their habitats. Field studies lasted more than 70 days and included over 60 locations across the country. Focal groups were species listed in Annex II: Triturus cristatus, T. dobrogicus, T. ivanbureschi, T. macedonicus, Testudo graeca, T. hermanni, Emys orbicularis, Elaphe quatuorlineata and Vipera ursinii. Results of these studies provided a more precise geographic distribution of crested newts and their hybrid zones in Serbia. For two species, we proposed the protection of two locations at the national level: one in eastern Serbia (for T. ivanbureschi) and one in southern Serbia (for T. macedonicus). The most threatened regions, where massive habitat losses and changes were detected, are the valleys of Velika and Zapadna Morava rivers, as well as wetlands along the Danube and Sava rivers. Populations of crested newts in Serbia are endangered by several threatening factors: habitat destructions/alterations, agriculture, water pollution and climatic changes. For reptiles, the most important locations for conservation of species listed in Annex II were detected in southeastern, southern and southwestern Serbia. For three reptile species with limited distribution and small populations, we proposed two locations in southern and southwestern Serbia for protection at the national level. The main threats for those species are habitat destruction/alternation and climatic changes. Results of these studies pointed out inconsistencies in conservation priorities between the national and European levels.

For two species, we proposed the protection of two locations at the national level: one in eastern Serbia (for T. ivanbureschi) and one in southern Serbia (for T. macedonicus). The most threatened regions, where massive habitat losses and changes were detected, are the valleys of Velika and Zapadna Morava rivers, as well as wetlands along the Danube and Sava rivers. Populations of crested newts in Serbia are endangered by several threatening factors: habitat destructions/alterations, agriculture, water pollution and climatic changes. For reptiles, the most important locations for conservation of species listed in Annex II were detected in southeastern, southern and southwestern Serbia. For three reptile species with limited distribution and small populations, we proposed two locations in southern and southwestern Serbia for protection at the national level. The main threats for those species are habitat destruction/alternation and climatic changes. Results of these studies pointed out inconsistencies in conservation priorities between the national and European levels.",

AB  - Prey animals have a wide array of strategies that they use to avoid or deter predators. In some cases, these strategies include warding off a predator attack by advertising strong chemical defences, such as venom, or by mimicking sympatric species, which do possess such defences (i.e. bluffing/mimicry). Dice snakes are nonvenemous natricine snakes that often live in sympatry with vipers. These snakes also have an ample arsenal of antipredator behavioural displays that include bluffing, characterized by hissing (auditory mimicry) with head flattening and fake strikes (visual mimicry). We measured the occurrence of bluffing displays in four different localities; on Golem Grad Island and in Konjsko (North Macedonia), where dice snakes share their habitat with nose-horned vipers (Vipera mmodytes) while in the other two localities, Mal Grad Island (Albania) and Pančevački rit Serbia), vipers are not present. We analysed the effect of locality, size (snout to vent length) nd sex on occurrence of bluffing as an antipredator strategy. Our results show that the ccurrence of bluffing was significantly affected by locality and body size. Notably, in the two localities where dice snakes share the same habitat with vipers the occurrence of bluffing displays is significantly higher than in the two localities where vipers are not present. This possibly indicates a case of Batesian mimicry, reported for the first time in dice snakes. Additionaly, our analysis shows that the predicted probabilities of the occurrence of bluffing increased with size. This seems intuitive, as bluffing behaviours should have a certain size threshold when they become effective, since small snakes can be easily consumed.

AB  - The meadow viper is the smallest and most endangered European viper, mostly due to the high level of habitat specialisation, low dispersal ability and fragmented distribution. In the Balkan Peninsula, isolated populations of Vipera ursinii macrops inhabit alpine and subalpine meadows above 1000 m. Here we updated the distribution of the meadow viper in the Mokra Gora Mt., SW Serbia, and revised the conservation threats affecting this subspecies and its habitats. Field sampling effort totalled 25 field days in spring and summer 2020-2022. A total of 8 vipers were found, distributed by three 1x1 km grid cells. Ecological models (developed using Maxent) based on climate and land-cover variables identified 28 grid cells on Mokra Gora Mt. with suitable conditions for the occurrence of meadow viper. The most important environmental factors related to its distribution were maximum temperate of the warmest month, precipitation of the driest and warmest quarters, annual potential evapo-transpiration, and land-cover (moors and heathlands, natural grasslands). Local conservation threats (following IUCN standard threats) include the potential development of tourism and recreation areas, renewable energy (windmill farms), logging and wood harvesting, with associated developments of road networks, and habitat shifting and alteration (abandonment of traditional pastoral farming and climate change). The low number of individuals detected in comparison to other Balkan populations suggests very small local populations. Additional localities in Serbia were identified as suitable for meadow viper occurrence (e.g. Jadovnik and Javorje Mts.) and they should be targeted for future sampling. Long-term conservation of the subspecies at the Mokra Gora Mt. requires a better regulation of logging and building activities, in order to safeguard the currently occupied habitats. The region should be considered for classification as a protected area, given the occurrence of other animal and plant species, which might lead to better habitat protection.

AB  - National parks are, by definition, areas set aside for wildlife protection, but also 
human recreation. Sometimes, the development of tourism-related infrastructure and 
capacities or resource exploitation can impede the primary function of national parks 
– nature conservation. Baseline and trend monitoring are great tools to assess human 
pressure on nature. Amphibian and reptile species have small ranges and are 
vulnerable to changes in their environment which makes them great bioindicators. 
Here we present the results of five-year monitoring activities of amphibian and reptile 
populations at National Park „Kopaonik“, Serbia. Data on batracho- and herpetofauna 
of NP „Kopaonik“ were limited and outdated, so a detailed survey of species richness, 
habitat conditions, and population trends was greatly needed. Starting from 2018 to 
2022 we described the amphibian and reptile diversity of the national park and 
systematically monitored several habitats, dispersed throughout all three protection 
zones as well as outside protection zones, to assess the habitat quality and population 
trends of selected species. We had an opportunity to see the effect of the international 
travel ban (due to the Covid19) on batracho- and herpetofauna, when much more 
people spent their vacation at NP „Kopaonik“ than usually. Per our results so far, the 
richness of the amphibians and reptiles species of the NP „Kopanik“ is moderate (9 
amphibian and 12 reptile species). The population size of the selected lizard species is 
stable through the years regardless of the protection zone. Amphibian populations are 
also stable, as offsprings of the majority of the species were found every year. However 
human pressure on the amphibian and reptile species is high. Habitat degradation is 
present and some localities are at great risk to be lost
