The present study deals with the inter-relations in the relief which forms the Bacia do Alto Rio Paraguay (BAP) in mid-west Brazil. The overall aim is to discuss the relationship between relief forms and the biodiversity of the Pantanal. The BAP is a natural environmental system with contrasts in two of the compartments on which it is formed: the plateau, the most elevated compartment, highly t...

Digital elevation models (DEMs) are increasingly used for visual and mathematical analysis of topography, landscapes and landforms, as well as modeling of surface processes. A DEM of Cerro Sillajhuay, a volcano in the Andes of Chile/Bolivia, was developed from ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) satellite data. The original 30-m DEM was generated by using tie ...

Two loud explosions accompanied by two successive big dark clouds that would have been 300 metres high, had taken place at El Humazo geothermal manifestation at February 2003. These explosions produced some important geomorphologic and structural changes that were registered in the geothermal area and its surroundings. Among these, it can be mentioned the reactivation of a geothermal manifestat...

[1] We propose a methodology for upscaling biomass in a river using a combination of dimensional analysis and hydro-geomorphologic scaling laws. We first demonstrate the use of dimensional analysis for determining local scaling relationships between Nostoc biomass and hydrologic and geomorphic variables. We then combine these relationships with hydraulic geometry and streamflow scaling in order...

Chlorides commonly precipitate during the evaporation of surface water or groundwater and during volcanic outgassing. Spectrally distinct surface deposits consistent with chloride-bearing materials have been identified and mapped using data from the 2001 Mars Odyssey Thermal Emission Imaging System. These deposits are found throughout regions of low albedo in the southern highlands of Mars. Geo...

This study provides the first maps of variations in bacterial community structure on a broad scale based on genotyping of DNA extracts from 593 soils from four different regions of France (North, Brittany, South-East and Landes). Soils were obtained from the soil library of RMQS ('Réseau de Mesures de la Qualité des Sols' = French soil quality monitoring network). The relevance of a biogeograph...

The study attempts to monitor geomorphological changes (e.g., erosion/deposition) with innovative tools at a typical Mediterranean torrent. torrent’s conditions are studied for an entire affected stream reach. investigation utilizes two different environments/point views: (a) traditional terrestrial and (b) aerial. methods include erosion pins streambanks field cross-section measurements of the...

O ver the last 25 years, a series of studies has investigated the diurnal formation and destruction cycle of temperature inversions in valleys and basins (for a review see, e.g., Whiteman 1990). In most of the valleys and basins that have been studied to date, advective influences produced by the well-known, diurnally reversing upand down-valley wind systems have greatly complicated the analyse...

Rivers and streams are heterogenous ecosystems that host a great number of vascular plant communities. The territory Slovenia is highly diverse regarding geomorphologic, geologic, climatic, edaphic conditions. We presumed environmental variability will also affect the distribution hygrophilous plants in running waters consequently structure communities they form. analyzed macrophyte, spatial, p...
