Horizontal air temperature is defined by the value of the mean air temperature for a certain surface area unit.  It is defined by the value of horizontal thermal gradient, i.e. the value of average change of horizontal temperature per unit area. In order to define the horizontal change of air temperature in Bosnia and Herzegovina, a GRID thermal model was constructed whose spatial resolution is 20 m. Based on obtained thermal model geo-database it was determined that the mean annual air temperature for the whole area of Bosnia and Herzegovina is about 10.9 °C, keeping in mind that there are significant thermal differences with respect to the two existing climate zones. More specifically, on the territory of the northern temperate climate zone the average annual temperature is about 9.7 °C, while in the Mediterranean climate zone the said value is 12.1 °C. In this work, it was also found that thermal contrasts are very pronounced as well, due to the fact that average annual temperature in the highest mountain peak zones in southeastern  Bosnian highlands is negative and is found to be -1.4 °C (Maglić peak), while at the  Neum coastal zone it is measured at 15.9 °C. The above stated pronounced thermal contrasts are determined on a small horizontal distance, as a consequence of climactic position of Bosnia and Herzegovina as well as highly pronounced terrain dynamics. 

Williams et al. (Nat. Genet. 48:238-224, 2016) recently reported neutral tumor evolution in one third of 904 samples from The Cancer Genome Atlas. Here, we assess the reproducibility and validity of their method and the extent of positive selection in subclonal mutations across cancer types. Our results do not support observable neutral tumor evolution and uncover strong positive selection within subclonal mutations across cancers.

The results of the first study of the dragonfly fauna in northwest Bosnia are presented. Field surveys were conducted in summer 2012 and 2013, resulting in the identification of 36 species. Out of these, 34 are new for the region. The present paper gives a detailed overview of the results and a comparison of the dragonfly fauna composition of the region studied with the neighboring areas within Bosnia and Herzegovina and Croatia is made. The most abundant species were: Calopteryx virgo (Linnaeus, 1758), Sympetrum sanguineum (Müller, 1764), Onychogomphus forcipatus (Linnaeus,1758), Somatochlora meridionalis Nielsen, 1935, Calopteryx splendens (Harris, 1782) and Platycnemis pennipes (Pallas, 1771). Noteworthy are the records of Chalcolestes viridis (Vander Linden, 1825) and Coenagrion scitulum (Rambur, 1842), two species that are rare in Bosnia and Herzegovina, and also Coenagrion ornatum (Selys, 1850) and Cordulegaster heros Theischinger, 1979, species of European conservation concern. Distribution and the status of these species and the conservation of dragonfly species in the country are briefly discussed. The data collected represent an important contribution to the knowledge of the dragonfly fauna of the Una River basin and Bosnia and Herzegovina.
