Because deserts are characterized by low food availability, high ambient temperature extremes, and absence of drinking water, one might expect that birds that live in these conditions exhibit a lower basal metabolic rate (BMR), reduced total evaporative water loss (TEWL), and greater ability to cope with high air temperatures than their mesic counterparts. To minimize confounding effects of phy...

Coherence change detection (CCD) is a remote sensing technique used to map phenomena that, under certain conditions, can be directly related changes in Interferometric SAR (InSAR) coherence. Mapping the areas affected by sediment transport events arid environments one of most common applications CCD. However, reliability these maps remains an unsolved issue. This paper focuses on verifying that...

Contamination of soil and water due to the release of light non-aqueous phase liquids (LNAPLs) is a ubiquitous problem. The problem is more severe in arid and semi-arid coastal regions where most of the petroleum production and related refinery industries are located. Biological treatment of these organic contaminated resources is receiving increasing interests and where applicable, can serve a...

On-farm production of protein is limited in most dairy farm operations in arid and semi-arid environments. Cereal-legume intercropping could be a viable option to obtain forage with higher protein content. A two-year experiment was conducted during 2009 and 2010 growing seasons in a loamy soil to determine whether intercropping pattern of barley (Hordeum vulgare L.) and annual medic (Medica...

this paper argues that the geovisualization research should go beyond the development of geovisual analytic toolbox, and pay attention to supporting human work in broad activity scale. Future generations of virtual geographic environments are expected to be capable of monitoring and recognizing context changes, reasoning about implications, and adjusting its service behavior accordingly. This w...

Geosimulation aims at modeling systems at the scale of individuals and entity-level units of the built environment and provides a new way to simulate how geographic spaces can be used by their future users, particularly in urban environments. In the MAGS Project we are developing a generic software platform for the creation of Multi-Agent Geo-Simulations involving several thousand agents intera...

an agroecological zones (aez) map is an essential tool for agricultural planning. by integrating the key components of the agricultural environments, it offers a bird's-eye view of internal diversity, agricultural potential and constraints that decision-makers find easier to understand than a pile of single-theme maps. in this study, aez map of the karkheh river basin has been prepared usi...
