One of the least understood aspects of aquatic ecology is the role of riparian zones of lakes, and how these habitats and their functions are impacted by human development of lakeshores. We investigated the effects of residential lakeshore development on littoral coarse woody debris (CWD) distribution and on riparian forest characteristics by comparing 18 lakes in the U.S. Pacific Northwest wit...

In the vast Algerian Sahara, the climate is typically desert, characterized by heat and dryness all year, which contributes to a very pronounced aridity. The aim of this study is to investigate the impact of this arid environment on automotive paints. Four paint samples with different durations of use were tested. Initially, a visualization of the surface condition by optical microscopy and...

continuing agricultural expansion and urban development in saudi arabia, (located in an arid climate), together with an increased demands for more water supplies, calls for more efficient irrigation practices, and an increase in crop water productivity (cwp). throughout the present study, a deficit irrigation system was investigated for its impact on soil salinity, crop response factor (ky), cw...

Decision makers in the American states tend to emulate policy innovations adopted in other states that they regard as legitimate points of comparison As a result of this decision rule, regional clusters of states have emerged whose policies closely resemble each other (The Science Citation Index® (SCI®) arid the Social Sciences Citation Indes® (SSCI®) indicate that this paper has been cited in ...

Kogan and Trahtman [2003. The moisture from the air as water resource in arid region: hopes, doubts and facts. Journal of Arid Environments 53, 231–240] analysed the functioning of a passive dew condenser built by F.I. Zibold in 1912 in Feodosia, and proposed a model to explain how thousands of litres of condensed water might be generated per day based on Zibold’s design. In a previous publicat...

New Zealand Journal of Ecology (1997) 21(2): 129-140 ©New Zealand Ecological Society these conceptual extremes should be seen as being endpoints of a range of possible situations, and not as discrete alternatives. It is therefore unlikely that an observed field situation would be completely described by any one of the models alone. More recently developed models use the conceptual extremes as c...

The rammed earth walls were greatly affected by the change of temperature fields in arid environments, particularly swell-shrink stress caused gradient variations was one main factors leading to surface weathering sites. While heat conduction, convection, and radiation resulting walls. In this study, thermocouple sensors embedded a rammed-earth test wall, continuously monitor field wall from ne...
