1 ABSTRACT As a professionally-oriented discipline, education in landscape architecture requires a curriculum with the fundamental capacity to both teach the skills necessary to operate within the contemporary expectations of practice while expanding the nebulous intellectual boundaries of the discipline. Emerging pedagogical frameworks in education are shifting to a more systems-based approach...

1 The relative importance of regional species pools and local ecological processes in governing landscape variation in plant species diversity and productivity was evaluated in a Kansas grassland. 2 We examined the impact of multispecies sowing treatments and experimental canopy disturbances on plant species diversity and ecosystem processes along a complex natural gradient of plant standing cr...

tehran the capital city of iran, with a population of about 8 million and an area of over 700 km2 is one of the most polluted metropolises in the world. tehran is suffering from a tremendous reduction in its sink capacity for absorption and assimilation of pollution which is generally due to uncontrolled urban sprawl and failure in consideration of ecological aspects into regional land use plan...

Although the vulnerability assessment of forest parks is used to determine the threats they face, a rapid and holistic framework has not been established well. The primary objective of this study is to adopt a framework for rapid assessment of forest parks vulnerability, examined in Lavizan forest park in Tehran (Iran) as the case study. The vulnerability assessment has been conducted, using th...

the distinguishing characteristic in the third millennium is planning based on principles of sustainable development in line with nature and all activities related to urban issues. ecological concepts and consequently ecological park refers to a comprehensive and integrated set of measures which create coordination, balance between the constituent elements of the park in order to establish sust...

This study was conducted to evaluate the effect of copper extraction on the structure and function of rangelands ecosystem around the mine area in Dareh Zereshk, Yazd province, Iran. Three study sites were considered at the specified intervals of the mine (0-200, 200-500 and 500-1000m). This research was conducted from 2012 to 2013. In each location, three linear transects with a length of 50 m...

Little is understood about how environmental heterogeneity influences the spatial dynamics of sexual selection. Within human-dominated systems, habitat modification creates environmental heterogeneity that could influence the adaptive value of individual phenotypes. Here, we used the gray catbird to examine if the ecological conditions experienced in the suburban matrix (SM) and embedded suburb...

degradation model was introduced as an instrument of environmental impact assessment (eia) in iran. several methods are introduced in rapid environmental assessment, but none of them have evaluated landscape level. thus, the main objective of this research is to introduce a new spatial method for eia by using landscape metrics. a benefit of rapid assessment by using ecological landscape metrics...

Although complexity and vulnerability assessment of mountain landscapes is increasingly taken into consideration, less attention is paid to ecophronesis-based solutions so as to reduce the fragile ecosystem vulnerability. The main propose of this study is to provide an insight of mountain complex landscape vulnerability and propose ecophronesis-based solutions in strategic planning framework fo...

Land use affects ecosystem stability and agricultural ecological security in black soil regions. Additional attention is required regarding the impact of different land-use patterns on soil. However, construction sustainable environments a dynamic process that depends reviews experts statistical analyses literature data. This study quantitatively reviewed past 20 years Using superposition exper...
