landscape fragmentation has threatened the landscape continuity of ray which was maintainedfrom prehistoric times until recent decades. from 19th century that tehran sprawl growth affected ray’slandscape as a satellite city of tehran, ray experienced rapid landscape fragmentation and underwent manychanges. in order to cope with the threat, the process of changes from landscape fragmentation sho...

introduction urban landscape is experiencing rapid changes which put all urban domains under pressures. these processes revolutionize urban landscape into spaces without ecologic values. the sustainability of green patches and corridors has been scathed by lack of ecological approaches in planning and design. therefore, urban green spaces structures and functions have been damaged. green spaces...

Convincing arguments for using critical realism as an underpinning for theories of IT-associated organizational change have appeared in the IS literature. A central task in developing such theories is to uncover the generative mechanisms by which IT is implicated in organizational change processes, but to do so, we must explain how critical realism’s concept of generative mechanisms applies in ...

Assessment in clinical psychology typically relies on global retrospective self-reports collected at research or clinic visits, which are limited by recall bias and are not well suited to address how behavior changes over time and across contexts. Ecological momentary assessment (EMA) involves repeated sampling of subjects' current behaviors and experiences in real time, in subjects' natural en...

Poverty analysis is often based on national level indicators that are compared over time or across countries. The broad trends that can be identified using aggregate information are useful for evaluating and monitoring the overall performance of a country. For many policy and research applications, however, the information that can be extracted from aggregate indicators is not sufficient. Resea...

Sorption-desorption processes control soil-pollutant interactions. These processes determine the extent of pyrene transport in soils. Understanding sorption characteristics of pyrene is necessary in ascertaining its fate in soil. Laboratory batch experiments were conducted to study the sorptions-desorption of pyrene on eight soils from varying tropical agro-ecological zones (AEZs). The results ...

Current federal regulatory limitations in protecting vernal pools can be attributed to incomplete data on the status of vernal pools statewide, lack of a methodology for assessing the functions of vernal pool ecosystems, failure to incorporate contemporary ecological principles into the development of compensatory mitigation strategies, and a piecemeal regulatory approach that results in admini...

The global environment is in critical decline. Whether one's concern about environmental epidemiology stems from the perspectives of environmental health, climate change, ecological collapse, or growing inequity, clear problems exist. Natural capital resources are being depleted; disregard for the integrity of ecosystems is entrenched in current business practices. Indeed, despite increasing rh...

Active economic development of the Lower Angara zone requires creation a scientific basis for long-term monitoring state natural ecosystems. The paper gives an assessment diversity vegetation cover in potential influence Nizhneboguchanskaya HPP. An analysis its typological structure on landscape-ecological is given. results DCA ordination and interpretation leading axes variation demonstrated p...

Landscape ecology, if not ecology in general, is largely founded on the notion that environmental patterns strongly influence ecological processes [1, 2]. The habitats in which organisms live, for example, are spatially structured at a number of scales, and these patterns interact with organism perception and behavior to drive the higher level processes of population dynamics and community stru...
