Research ArticleOpen accessIn the abstractArthropods in Natural Communities in Mescal Agave (Agave durangensis Gentry) in an Arid ZoneMaría P. González-Castillo, Manuel Quintos Escalante, Gabriela Castaño-MenesesProblem statement: The arthropods have a very important role in the arid zones due to their interactions with many organism and because they constituted an important element in the structure of the plant community. Nevertheless their importance there are few knowledge about the community of arthropods associated to vegetation in arid zones in the North of Mexico. The present study … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 8,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing the Fertility of Soils under Khaya ivorensis Plantation and Regenerated Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem statement: It is widely accepted that conversion of natural forest to other land use types leads to deterioration of soil fertility and increased soil compaction which consequently become degraded secondary forests. Degraded secondary forest or forestland is indicated by low in soil fertility and organic matter due to imbalance input and output from original vegetation. Forest plantation through planting … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractVegetation Analysis of Sutan-Chay Basin in ArasbaranT. Ebrahimi Gajoti, V. Haciyev, A. Javanshir et al.Problem statement: Plants associations differ in relation to environmental gradients. Therefore, it is necessary to study the interaction between ecological factors and vegetation. Approach: In this study vegetation and flora of Sutan-Chay Basin in Arasbaran was investigated using Braun Blanquet method as physiognomic floristic. Sampling of soil and vegetation was carried out by selecting areas with homogenous plant compositions. The … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractFreshwater Situation in Kuwait-Remote Sensing Inputs on Possibility of Artificial RechargeM. Al-Murad, S. Uddin, A. Al-DousariProblem statement: Kuwait is an arid country having per capita freshwater consumption of 485 l day-1. Almost the entire freshwater requirements are met through desalination. The water tariffs in the country are very low consequent to 60% subsidy provided by the government. The use of tertiary treated wastewater is restricted to irrigation and forestation; this leaves huge surplus that can … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 7,409 accessesView PDFCite
