Globally, grassland soils, if managed properly, are important for the sake of carbon sequestration. The quality and quantity of soil organic carbon is probably influenced by vegetation traits such as composition and plant species. We determined the influence of vegetation composition and co-dominant species on soil organic carbon in two Prangus uloptera stands. The stands situated at close prox...

In this study the fish assemblages of the silted Aguas Claras stream (AC) was compared with that of a reference, the São Carlos stream (SC), so as to identify potential fish indicators of integrity or degradation. Both streams, located about 5 km from one another, are part of the Upper Paraná river basin, Brazil, and present similar physiographical features. Twenty-one species were collected in...

Geographic information system (GIS) has had a great progress in river engineering in recent years. Most of new developed softwares in this area have the GIS abilities or are able to interact with GIS software. The application of GIS in this area is mostly for pre and post processing of input and output data. In this research, water flow of river has been estimated in an ungaged point using ArcV...

Abstract The influence of seasonally frozen ground (SFG) on water, energy, and solute fluxes is important in cold climate regions. hydrological role permafrost now being actively researched, but the SFG has received less attention. Intuitively, restricts (snowmelt) infiltration, thereby enhancing surface runoff decreasing soil water replenishment groundwater recharge. However, reported effects ...

Lacustrine thermokarst is receiving great interest as a landscape-forming process. Despite this, research dealing with the quantitative analysis of changes in morphological patterns plains under ongoing climate change lacking. This study aims to analyze cryolithozone landscapes based on models provided by mathematical morphology landscapes. Our involves eight key sites within lacustrine and nin...
