Ecological succession is one of the most important concepts in ecology. However for microbial community succession, there is a lack of a solid theoretical framework regarding succession in microorganisms. This is in part due to microbial community complexity and plasticity but also because little is known about temporal patterns of microbial community shifts in different kinds of ecosystems, in...

The northern piedmont of the western Kunlun mountains (Xinjiang, China) is marked at its easternmost extremity, south of the Hotan-Qira oases, by a set of normal faults trending N50E for nearly 70 km. Conspicuous on Landsat and SPOT images, these faults follow the southeastern border of a deep flexural basin and may be related to the subsidence of the Tarim platform loaded by the western Kunlun...

Morphological and sedimentological responses of streams to basin-scale impact have been well documented for intensively agricultural or urban areas. Sensitivity thresholds of streams to modest levels of disturbance, however, are not well understood. This study addresses the influence of forest conversion on streams of the southern Blue Ridge Mountains, a region that has received little attentio...

We use the landcape evolution model Zscape to explore quantitatively the development of mountainous topography in the Basin and Range province (formerly the Basin Ranges), USA, as a function of faulting, surface processes and microclimate. Many of the classic morphologies of mountains in the Basin and Range were described in the late part of the 19th century. The varied topography coupled with ...

We described newly discovered baenid specimens from the Uintan North American Land Mammal Age (NALMA), in the Uinta Formation, Uinta Basin, Utah. These specimens include a partial skull and several previously undescribed postcranial elements of Baena arenosa, and numerous well-preserved shells of B. arenosa and Chisternon undatum. Baenids from the Uintan NALMA (46.5-40 Ma) are critical in that ...

—The study objective was to investigate the response of salmonid populations to disturbance in Oregon Coast Range streams in two rock types, basalt and sandstone. Salmonid abundance was estimated in a total of 30 km of channel in 10 Oregon Coast Range streams with similar basin areas (14–20 km2). These basins had a range of disturbance caused by timber harvest, fire, and salvage logging. Mean c...

Introduction: The floor of the Hellas basin (Hellas Planitia) features unique landforms which have defied unambiguous interpretation [1-5]. We suggest that extensive subaqueous mass movements have been involved in the emplacement and deformation of the basin floor deposits, followed by intensive eolian erosion. Topography, Landforms, and Previous Interpretations: Hellas Planitia is characterize...

Introduction: The 3.8 km Steinheim Basin [1] in SW Ger-many is a complex impact crater with central uplift thought to have formed simultaneously with the 24 km and 14.4 Ma Ries crater [2] by the impact of a double asteroid. The crater is hosted by a sequence of Triassic to Upper Jurassic sedimentary rocks [1]. The Steinheim Basin exhibits an almost primary crater morphology , intensely brecciat...

The main formation of the Yinggehai Basin has been related to rotation Indochina block, resulting in large-scale strike-slip motion along Red River Fault Zone (RRFZ). Transrotational tectonics played a key role evolution Basin. In this study, we present analog experiments with preexisting basal velocity discontinuity boundary, crustal blocks concerning vertical axes, and syntectonic sedimentati...

Evaporite mobilisation in evaporite-cored anticlines leads to topographic growth that can alter sedimentary routing shallow marine environments. This paper analyses two perpendicular the NW Africa coast understand how their tectonic evolution influenced sediment pathways during Early Middle Jurassic and Cretaceous exhumation of Mesozoic margin hinterland. The Essaouira-Agadir Basin Morocco unde...
