Sustainable agricultural practices in conjunction with ecological restoration methods can reduce the detrimental effects of agriculture. The Society for Ecological Restoration International has produced generic guidelines for conceiving, organizing, conducting and assessing ecological restoration projects. Additionally, there are now good conceptual frameworks, guidelines and practical methods ...
water is an essential yet constrained commodity for human communities and ecological systems depend on it. with population growth and economic development, water resource is increasingly declining. over the past two decades, because of changes in population and climate, and relative welfare increase, the per capita consumption of water has increased. thus, optimal use of available water resourc...
Changing agricultural experts' attitude toward sustainability principles and perceptions is essential to create sustainable agriculture. Various studies had shown that permanent changes are not easily accessible to maintain ecological values. Therefore preparing effective information channels and precautions leading to communication system firmness are important challenges ahead. The purpose of...
A representational approach to ecological psychology is presented. This paper identifies a computational-level commonality in ecological psychology research related to passability of apertures. It is argued that a cognitive mechanism capable of comparing the geometric properties of an environment and the geometric properties of the agent can be used to support judgments for action in space.
An alternative view of presence is introduced based on existential philosophy and ecological psychology. This view favors a Heideggerian/Gibsonian metaphysic over the more conventional rationalistic orientation. In this alternative view, notions of subjective presence and objective presence no longer exist. Presence is instead tied to one’s successfully supported action in the environment, this...

land use planning is a science that determines the type of land use through studying the ecological character of the land as well as its socio-economic structure. it is possible to plan for the appropriate use of the land and to enhance the present management of the land use by utilizing geographical information system (gis). to this end, our investigators identified and took steps toward devel...
Ground beetle assemblages were compared in organic, no-till, and chisel-till cropping systems of the USDA Farming Systems Project in Maryland. The cropping systems consisted of 3-yr rotations of corn (Zea mays L.), soybean (Glycine max L. Merr.), and wheat (Triticum aestivum L.) thatwereplanted to cornand soybeanduring the2yrofÞeld sampling (2001Ð2002).Eachyear, ground beetles were sampled usin...
BACKGROUND Predicting habitats prone to favor disease transmission is challenging due to confounding information on habitats, reservoirs, and diseases. Comparative analysis, which aims at investigating ecological and evolutionary patterns among species, is a tool that may help. The emergence of zoonotic pathogens is a major health concern and is closely linked to habitat modifications by human ...
