Morphologic variability from 25 populations of Acer campestre L. in Bosnia and Herzegovina was analyzed. Morphometric structure of variability and between-population variability was performed based on 10 fruit-parameter characteristics and 19 leaf-parameter characteristics using multivariate statistical analysis. Results confirmed the separation of three submediterranean populations as a group in relation to other tested populations, from which the Banja Luka population is different. Measured leaf parameters were confirmed as a predominant carrier of the morphologic separation between populations. In other Acer species populations within A. monspessulanum and A. intermedium species are separated mainly by fruit and much less by leaf parameters. The southernmost submediterranean populations from Trebinje, Ljubuški, and Mostar regions have smaller leaf areas, which consequently places them within the same morphologic group; their variability is in tight connection with eco-geo-graphical factors, where the ecological distance is a much better predictor of morphological variability compared to geographical distance. The air temperature had the biggest influence on morphological variability regarding the highest in-between correlation. Achieved results may serve for the continuation of the research in other areas of Acer campestre to determine the interactive effect of ecological, geographical, climatic, and migrational factors on their morphologic population plasticity.

The Relationship

Mammalian carnivores are rarely incorporated in paleoenvironmental reconstructions, largely because of their rarity within the fossil record. However, multivariate statistical modeling can be successfully used to quantify specific anatomical features as environmental predictors. Here we explore morphological variability of the humerus in a closely related group of predators (Felidae) to investigate the relationship between morphometric descriptors and habitat categories. We analyze linear measurements of the humerus in three different morphometric combinations (log-transformed, size-free, and ratio), and explore four distinct ways of categorizing habitat adaptations. Open, Mixed, and Closed categories are defined according to criteria based on traditional descriptions of species, distributions, and biome occupancy. Extensive exploratory work is presented using linear discriminant analyses and several fossils are included to provide paleoecological reconstructions.We found no significant differences in the predictive power of distinct morphometric descriptors or habitat criteria, although sample splitting into small and large cat guilds greatly improves the stability of the models. Significant insights emerge for three long-canine cats:Smilodon populator,Paramachairodus orientalis, andDinofelissp. from Olduvai Gorge (East Africa).S. populatorandP. orientalisare both predicted to have been closed-habitat adapted taxa. The false “sabertooth”Dinofelissp. from Olduvai Gorge is predicted to be adapted to mixed habitat. The application of felid humerus ecomorphology to the carnivoran record of Olduvai Gorge shows that the older stratigraphic levels (Bed I, 1.99–1.79 Ma) included a broader range of environments than Beds II or V, where there is an abundance of cats adapted to open environments.

AbstractThe present study aimed to reveal genetic diversity and population structure in three Onosma species i.e., Onosma bulbotrichum DC., O. elwendicum Wettst. and O. sericeum Willd. (Boraginaceae) growing in Iran. This study was performed to check if the ISSR molecular markers could be used in the Onosma species delimitation. We also investigated the infra-specific morphological variability and if we can identify infra-species taxonomic forms. The present study revealed within species genetic and morphological diversity. ISSR data could delimit the studied species as they were separated from each other in NJ tree, maximum parsimony and STRUCTURE analysis. AMOVA and Hickory tests produced significant genetic difference among the studied species. The Mantel test showed no correlation between genetic distance and geographical distance of the populations for all three species. Reticulation analysis and Nm estimation showed gene flow among these populations. We could identify a few ISSR loci that are adaptive. Data obtained can be used in conservation of these medicinal plants in Iran.

After the conquest of the Bosnian and Herzegovinian territory, the Romans  launched numerous campaigns so this region and its population could be incorporated into the Roman life and Roman civilization of that period as quickly as possible. They believed that this is the only and the best way to make themselves the masters of this region. As part of their extensive activities, those that focused on systematic and full implementation of urbanization in the present-day Bosnia and Herzegovina were especially important. This long process encompassed the infrastructure construction, modelled on the Italic cities, villages, economic and other facilities. The first steps of the Roman authorities were to construct modern and high-quality roads, i.e. a powerful road network that would facilitate a faster and stronger connection between settlements and economic resources around present-day Bosnia and Herzegovina. Publius Cornelius Dolabella, who served as an imperial governor of the province of Upper Illyria from 14 th  to 20  AD, had a special role in the implementation of this plan. The construction of the first roads began upon his initiative and under his strict supervision. He intended to establish a better connection between the regions of present-day Bosnia and Herzegovina with the eastern coast of the Adriatic Sea. These first roads created good foundation for a complete urbanization of this area. th Along with the road construction, the Romans launched the activities that included new settlements, firstly along the Roman roads, then at the crossroads, and then in the regions had were rich in resources. Each settlement, in its appearance, dimensions and layout of facilities and its infrastructure, had to correspond to the Roman building standards. The first settlements were built along the roads. The most famous sites of urban settlements include: Grkovci and Pelva (Livno plateau), Halapići and Salvium (Glamoč plateau), Pecka (the Sana river valley), Baloie (Šipovo), Bjelajac (Mrkonjić Grad), Castra, Laktaši, Gornji Šeher (Banja Luka), Servitium (Bosanska Gradiška), Delminium (Duvno plateau), Varvara (Rama river valley), Ad Matricem (Gornji Vakuf), Bistue Nova (Bugojno), Višnjica (Kiseljak), Ilidža (Sarajevo plateau), Domavia and Skelani (central Podrinje), Blagaj, Maslovare and Bosanski Novi (the Sana and Japra rivers valley), Golubić (Bihać), Bigeste (Čapljina), Leusinium (Bileća), Diluntum (Stolac), Ad Drinum (Drinjača) as well as many others, but less known.  Urbanization had many positive effects in all aspects of work and life of local inhabitants from that period in the region of present-day Bosnia and Herzegovina. A road network was established, as well as numerous economic activities, lifestyle standard and social relations were raised to a significantly higher level, many settlements (cities and villages) and many cultural monuments were built.

The Cost

Economic profit is the concept immanent for the value added. It is an attempt to analyze properly the business success in terms of contribution of profit to the increase in the company value and the stockholders’ wealth. Fundamentally, value added is a measure of the business success where all standard costs and the costs of invested capital are excluded from the realized revenues. Profit as a traditional measure of business success ignores the cost of equity, although equity is the most expensive form of capital. To illustrate better this concept, we made an analysis of the most profitable corporations in Bosnia and Herzegovina listed on Banja Luka and Sarajevo stock exchanges. The analysis showed that the majority of these corporations operate poorly because they do not meet the implicit cost of capital, essentially losing the value of capital entrusted to them by their stockholders. Also, this analysis questioned the importance of the industries which are usually considered to be the most important in BiH economy.

This study reports on morphological variability of Eimeria species, which may be given either by drawings or as quantitative data. The drawings may be used to facilitate identification by eye of ‘unknown’ Eimeria specimens, whereas quantitative data may serve as a reference set for identification by multivariate statistical techniques. The morphology of 810 Eimeria specimens was defined in binary (b/w) digital images by pixels of their oocyst outline. A Fourier transform of pixel positions yielded size and shape features. To classify coccidia, the quantitative data were employed in an agglomerative clustering by average linkage algorithm with equal weight assigned to size and shape. An inverse Fourier transform served to reconstruct oocyst outlines, i.e. outlines of average shape and size, from mean values of features in resulting clusters. Clusters were subsequently identified based on their average morphology by comparison with drawings of species in an earlier taxonomical work. Five hundred oocyst outlines were simulated for each cluster representing a species, and shape/size variability was presented in contour diagrams. Differences in species shapes, and correspondence in length and width, were seen after reconstruction by inverse Fourier transform and comparison with earlier studies.

The paper analyzes the recent trends in the occurrence of frost days in Bosnia and Herzegovina. Trends during the 1961-2015 periods were determined based on data from fourteen meteorological stations. MAKESENS procedure, which uses the nonparametric Mann-Kendall test and the nonparametric Sen?s method, was applied on time series of annual number of frost days to assess trends magnitude and its statistical significance. Given the results, negative and largely significant trends are present all over Bosnia and Herzegovina territory. The estimated decreasing trend was in the range of 2.1-6.4 days per decade. The percentile analysis of the annual number of frost days in Bosnia and Herzegovina suggests that a decreasing trend has become more pronounced since 1990s and particularly since the beginning of the 21st century. The observed downward trends were primarily a consequence of high negative trends in the coldest winter months - in January and December. The most prominent decrease in annual number of frost days was observed in Banja Luka, Bugojno, Zenica and Bjelasnica area. Further research on the effects of the determined trends in the frost occurrence on plants is necessary particularly due to the observed changes in plant phenology as a result of climate system warming.

The Church

The origins of initial education of the Serbian people in Bosnia and Herzegovina are found in the Serbian Orthodox churches and monasteries. Monks and priests, although having a modest education, also worked as teachers besides their regular religious functions. The first students were young men, who were trained in the profession of priests. They usually inherited this position from their fathers. The initial courses were of a limited religious character and were not able to provide a broader education to students. Literacy obtained within the sphere of the church could not respond to the needs and spirit of the new age in the middle of the 19th century. Therefore, it was prominent and wealthy Serbian merchants that made a strong impact in establishing modern private schools. Most Serbian schools were financially supported by Serbia and Russia during that century, up until the Austro-Hungarian occupation. Serbian Orthodox church – school municipalities very often addressed Belgrade for help for reconstruction or building schools and churches. The foundation of Pelagic’s Seminary in Banja Luka in 1866 made a significant impact on the cultural progress of Serbs, especially those living in the area of Bosanska Krajina.

This paper deals with the architecture of the most prominent architect in Bosnia and Herzegovina during the Austro-Hungarian time, Josip Vancaš, and two of his most appreciated designs developed for Banja Luka: Landesbank branch office and villa Husedžinović. They both belong to what Vancaš promoted to be "Bosnian style" in architecture, while the latter one is widely accepted as one of his best single-family housing designs. The paper foremost shows Vancaš's biography and a short overview of his professional development and then focuses on the discussion of his contribution to the so-called Bosnian style in architecture, and its reflections to mentioned designs in Banja Luka, originally contributing to this still active question in the history of architecture.The paper gives data on the original status of the buildings, as well as their development throughout history, with reflections to contemporary time. The concluding discussion reviews Vancaš's contribution to architecture in the period of 1878-1918, as well as the promotion of new thoughts outside the usual work of a typical architect.
