abstract soil invertebrate and their spatial pattern are affected strongly by environmental factors. spatial variability of soil properties is one of the most important reasons of the macrofauna variability. this study was conducted to investigate the spatial variability of soil properties and soil macrofauna biomass in the riparian forest landscape of karkhe river. soil macro fauna were sample...

introduction one of the critical issues associated with sustainability in the twenty-first century is how cities are growing and developing in the space. rapid urban growth and physical development of cities cause disintegration of the spatial organization of cities and consequently spatial inequality between urban spaces. this phenomenon can be considered as spatial segregation or fragmentatio...

background: cyclooxygenase (cox) enzyme known as a regulatory factor in synaptic plasticity. it has been reported that synaptic plasticity is one of the mechanisms involved in learning and memory processes. in the current study peripheral injection's effects of sodium salicylate (as a non selective cox inhibitor) on spatial learning and memory have been investigated. methods: four groups of mal...
