Caeoma cassiopae sp. nov. (Uredinales) is described on the arctic-alpine shrub Cassiope tetragona. It was found in three locations in the Rocky Mountains of west-central Alberta, and is the first rust reported on the genus Cassiope. The sori resemble the uredinia of species in the genus Chrysomyxa. The host in the Ericaceae also suggests affinity with that genus. However, the spore morphology, ...

laudakia nupta, with numerous local populations through iran, is one of the most widely distributed species of the genus laudakia in iran. eight hundred and fifty nine bp of mitochondrial nd4-trnaleu were sequenced and analyzed for 47 specimens of laudakia nupta and three specimens of laudakia melanura, as an out-group taxon. all specimens were collected during field work in iran. based on bran...

The Atlas Mountains of Morocco display high topography, no deep crustal root, and regions of localized Cenozoic alkaline volcanism. Previous seismic imaging and geophysical studies have implied a hot mantle upwelling as the source of the volcanism and high elevation. However, the existence, shape, and physical properties of an associated mantle anomaly are debated. Here we use seismic waveform ...

Abstract. The Zagros orogenic system resulted due to collision of the Arabian plate with Eurasian plate. region is characterized by ocean–continent subduction and continent–continent collision, convergence velocity shows variations from east west. Therefore, this complex tectonic stress a wide range diffuse or localized deformation between both plates. in situ GPS data are very limited sparsely...

In an earlier paper^ I described the new genus Brooksma from a series of sediments in southeastern Alaska tentatively referred to the upper Silurian. In that paper will be found a brief discussion of the faunal affinities of the series. A more detailed study of the Brooksina fauna together with the famias of lower and liighei horizons strengthens the belief that the formations in question shoul...

Salt lithologies are mechanically weaker than other sedimentary rocks. horizons usually act as décollements and precursor salt bodies preferentially deform early during contraction, concentrate deformation, impact the structural style kinematics mountain building. Focusing on shortened isolated-diapir provinces, our analog modeling program investigates influence of two walls folding thrusting. ...

Turkey lies at the interface between distinctive archeological and biotic provinces.7 For example, the Middle Pleistocene sequences of the Levant and the Caucasus include many Acheulean assemblages, whereas Acheulean handaxes and biface technology are seldom found in the contemprary Lower Paleolithic assemblages of the Balkans. Likewise, areas surrounding Turkey, including the Levant, the Zagro...

The excellent preservation of the acritarchs, their great abundance, diversity and good stratigraphic control permit establishment of a detailed Middle and Late Cambrian acritarch biozonation. A total of 56 palynomorph species form the basis of 10 local acritarch assemblage zones. Assemblage zones I-II occur in the lower and middle parts of the Member C of the Mila Formation and suggest Early-m...

We present the geomorphological map of northwestern part Kurdistan Region Iraq, where landscape expresses tectonic activity associated with Arabia-Eurasia convergence and Neogene climate change. These processes influenced evolution landforms fluvial pathways, major rivers Tigris, Khabur, Great Zab incise Northeastern Mesopotamia Anticlinal ridges syncline trough compose Zagros orogen.
