Information regarding abundance and density of populations is necessary for their effective management and monitoring. The most commonly applied method on hunting grounds in the state hunting and forestry enterprises in Bulgaria is the spring census, i.e. counting the individuals of the game species in an area. To test its credibility, we studied t...

The red deer is a main game species in Bulgaria, as well as in large parts of Europe. However, its behaviour has not been studied in depth on a local scale, especially on the Balkans. This study presents the first GPS telemetry data for red deer in Bulgaria-in the Central and Eastern Balkan Mountains, the Rhodopi Mountains and the lowlands of North...

Telemetry is a widely utilized method to track animal movements and analyze behavior. So far, there have been no published studies on telemetry of red deer in Bulgaria. Here we present preliminary results from a pilot study from GPS/GSM telemetry. 10 red deer individuals (7 males, 5 of which subadults (approx. 1.5-year-old) and 3 adult females) wer...

Estimating population size and density for mammals which are not individually recognizable is particularly challenging. However, these indicators are vital for species management. In this study we make the first attempt to estimate the population density of the endangered in Bulgaria brown bear (Ursus arctos L.) using camera traps. Thirty eight cam...

Relevance. The problem of postoperative analgesia don’t lose it’s relevance despite the large implementation in practice the multimodal analgesia strategy. In prescribing the analgesia in the most cases don’t consider the predictors of intensive postoperative pain, which could to contribute the choice of ineffective postoperative analgesia. Purpose...

Introduction The presence of wild boar (Sus scrofa) (also known as feral pigs or wild hogs), in many ecosystems of the globe, has raised concerns about the impacts of this species on agriculture, collisions with vehicles, and because of the expected strong impact on wild ecosystems and biodiversity. Problems are exacerbated where this species is al...

The diet strategy of the wolf in Europe is reviewed on the basis of 74 basic and 14 additional literature sources. The comparative analysis reveals clear dependence on the latitude (and, therefore, on the changing environmental conditions) correlated with the wild ungulate abundance and diversity. Following a geographic pattern, the wolf is special...

An attempt was made to investigate if wild ungulates would have preferences to four oak species acorn on the base of their chemical composition. Wild boar preferred Q. pubescens and the least consumption is of Q. suber. Q. pubescens was also preferred by D. dama and C. capriolus. Both species consumed less Q. suber like the boar. The second preferr...

Xenon is widely used for maintenance of anesthesia, however the analgesic effect of this noble gas brings to an idea of its use in analgesic schemes. The first time antinociceptive features of Xe were described by B. Lachman and colleagues in 1988. It is well known that Xe realises its analgesic potential through powerful non-competitive blockade o...

This paper analyses the temporal variation in the size of home range and activity of adult wild boar (Sus scrofa L.). Eighteen boar were radiotracked between 1991 and 1993 in the Maremma Natural Park (Central Italy). Variations of home-range size and activity were related to sex, winter food availability and population density. The hypotheses that...

The number dynamics of the mouflon on the Capraia Island (the Tuscan Arcipelago) was studied during the period 2002-2006. The counting results revealed a stable trend towards increasing in numbers in 2002-2004, followed by almost constant number during the rest of the studied period. The mouflon inhabits about 1500 ha with a density varying from 2....

Osogovo mountain is located at the border area with R Macedonia and till the end of 80-ties was part of restricted border zone. This is a reason for the nowadays relatively well conserved habitats and low anthropogenic pressure, but on the other side determines Osogovo as one of the least studied mountains in Bulgaria. This study aims delivery of n...

Information about local population densities is essential to manage ungulates and is often obtained by pellet group counts. Estimating the rate of pellet group disappearance is critical for the reliability of this method. However, no studies have been performed an pellet group disappearance rates in Mediterranean climate, and no quantitative inform...

This study investigated the winter daily defecation rate (DDR) of fallow deer in a Mediterranean area, and reviewed the existing literature on the defecation rate of this species. A mean number of 26.5 pellet groups deer−1 day−1 was found in this study. This value was similar to that found in studies carried out in winter in the U.K. and Germany, s...

Black-billed Magpies (Pica pica) were observed pecking on fallow deer (Dama dama) on 56 occasions. Ectoparasite removal was apparently the reason for this interaction. Birds preferred deer that were sitting to deer that were standing, and interacted preferentially with adult males over females or calves. Deer did not solicit cleaning and, on a few...

The jackal was put under protective status in Bulgaria in 1962. This resulted in the spread of the jackal throughout the country by 1985. The animal turned into a pest for hunting and for domesticated animals. Hence, hunting quotas were introduced in the areas of Strandza and in the eastern part of Stara Planina, where jackals were most abundant. T...

Until 1950 the wolf was distributed throughout Bulgaria. Since this time, however, his occurrence has decreased considerably, so that today wolves are only to be found in the mountain regions bordering Greece, Turkey, and Yugoslavia. At times wolves can be found in Rumania and in Ludogorie. Data on the numbers of wolves left are based upon the numb...

In the last hundred years the range of the Brown Bear (Ursus arctos L.) in Bulgaria has diminished (Table 1). At the same time the numbers of bears declined until the year 1934. There then followed a ban on bear shooting. Currently only bears which have specialised in killing domestic animals may be shot. At the present time approximately 600 bears...

In the last 30 years, the wild boar of the North have spread 500 to 1000 km beyond their historical limit (illustration), in particular alongside rivers and in the vicinity of human settlements. They are even to be found on the line of latitude 64° N, by Bielomorsk. At the present time, wild boar are in almost their entire area of distribution in E...

In the Kurpiowska Forest, in 1975-1976, wild boars uprooted 305 ha of litter and herb layer, ie. 13.2% of the surface area of dry pine forest, and in 1976-1977, 48 ha (2.1% of dry wood) and also destroyed 41% of a pine sawfly population (Diprion pini). The level of rooting activity in the forests depended on climatic conditions, food abundance and...
