AB  - In this paper we confront widely accepted global climate stabilization goals (70% reduction of CO2 emissions) with the International Civil Aviation Organization's (ICAO) forecasts of future commercial aviation growth, in order to explore the real possibilities of realizing these climate stabilization goals. By using ICAO forecasts, we clearly show that, instead of the proclaimed 70% reduction of CO2 emissions, air transport's CO2 emissions are going to rise five-fold (4.9 times) in the 2005-40 period. But even if a 70% increase of aviation's energy efficiency and reduction of CO2 emissions could be somehow (miraculously) achieved, CO2 emissions of air transport would be higher by 50% in 2040 (than in 2005), due to the sudden increase in the volume of air-transport tourist trips. So, if the aim is to achieve ambitious energy consumption and GHG reduction for air transport within the next few decades, policies should aim at reducing total consumption, which means reducing VKT not just vehicle-specific consumption. Due to the extremely high growth rates in the volume of air traffic, it is highly unlikely that technical progress of engines will be sufficient to reduce overall emissions or even keep them at today's levels. Hence, the policy focus should shift to more rigorous and efficient implementation of market-driven instruments, which, apart from creating incentives to develop and use low-emission technologies, can also reduce the demand for travel.

AB  - In the Getic of the Carpatho-Balcanides (eastern Serbia) and the Tirgan Formation of the Kopet-Dagh Basin (northeast Iran), platform carbonates were deposited during the Barremian/Early Aptian in environments in the domain of the northern Alpine Tethys and deformed during the Alpine orogeny. In this study, Urgonian carbonate platform deposits are discussed in detail with regard to depositional facies, microfacies, biostratigraphy, palaeoenvironments and palaeoecology. Detailed sedimentological and palaeontological investigations have been carried out on five sections in eastern Serbia and three sections in northeast Iran supported by an analysis of 392 thin-sections. Petrographic analysis of thin-sections led to the recognition of eight microfacies types grouped into four facies zones. A supratidal-intertidal (restricted)-intertidal (open-lagoon)-platform-margin sand-shoal transition was recorded in both areas. Supratidal facies are characterized by bioclastic mudstones and fenestral and peloidal wackestones and packstones; intertidal (restricted) facies are represented by bioclastic wackestones, whereas intertidal (open-lagoon) facies are indicated by bioclastic packstones/grainstones and oncoid grainstones. High-energy sand-shoal fades are dominated by ooid grainstones/rudstones followed by orbitolinid packstones. Benthic foraminifera are especially abundant and along with calcareous algae are the most important fossils used for age determination of shallow-marine carbonate deposits. Thirty-two benthic foraminiferal genera were identified from eastern Serbia with an additional 38 genera from northeast Iran dominated by agglutinated forms. Identified calcareous algae provide significant data for depositional environments and palaeoecology. The microfossil associations in the two regions are very similar and share a number of common characteristics, but also some differences and show a strong affinity to those of the northern margins of Tethys. In both study areas shallow-marine environments of the Barremian/Early Aptian were replaced by deep-marine conditions during the Late Cretaceous. (C) 2012 Elsevier Ltd. All rights reserved.

AB  - This paper analyses the Serbian nature protection system in Belgrade. Effective protection of natural features in urban landscapes have become increasingly complex due to conversion of natural habitats, high levels of pollution and other forms of deterioration caused by human impact. These anthropogenic pressures vary in type and intensity and depend on the location of protected assets. Through comparative analyses of selected legally protected natural assets in various areas in the city, different features of spatially-functional coexistence and development are noted. According to the results of this research it is evident that various natural protected assets in highly urbanised conditions can sustain theirs primary ecological function and can also develop additional adjusted functions during time.

AB  - The biostratigraphy of the Upper Cretaceous volcanoclastic-sedimentary formations cropping out in the Timok Eruptive Area of the eastern Serbian Carpatho-Balkanides is presented. Four lithostratigraphic units of formation rank are recognized in the Timok area: Stublica Clastics (Upper Albian/Cenomanian), Ostrelj (Lower Turonian/Santonian), Bor Clastics (Campanian/Maastrichtian) and Bukovo (Campanian/?Maastrichtian). Forty two species of planktonic foraminifera have been determined in the studied area. Eight planktonic foraminiferal zones of Middle Cenomanian through Middle Campanian age have been recognized. These are: Thahnanninella reicheli Interval Zone (Middle Cenomanian), Rotalipora cushmani Taxon Range Zone (Upper Cenomanian), Helvetoglobotruncana helvetica Taxon Range Zone (Lower Turonian), Marginotruncana sigali-Dicarinella primitiva Interval Zone (Upper Turonian to lowermost Coniacian), Dicarinella concavata Interval Zone (Lower Coniacian to lowermost Santonian), Dicarinella asymetrica Taxon Range Zone (Santonian), Globotruncanita elevata Interval Zone (Lower Campanian) and the Globotruncana ventricosa Interval Zone (Middle Campanian). The scarcity or lack of zonal species in the Lower Cenomanian and Upper Campanian/Maastrichtian strata prevents recognition of the nominal zones. The Upper Cretaceous planktonic foraminiferal zones from the Timok Eruptive Area are correlated with coeval zones from adjacent regions of Bulgaria and Romania and from other Tethyan regions.
