forest types mapping, is one of the most necessary elements in the forest management and silviculture treatments. traditional methods such as field surveys are almost time-consuming and cost-intensive. improvements in remote sensing data sources and classification –estimation methods are preparing new opportunities for obtaining more accurate forest biophysical attributes maps. this research co...

BACKGROUND Green spaces have been associated with both health benefits and risks in children; however, available evidence simultaneously investigating these conflicting influences, especially in association with different types of greenness, is scarce. OBJECTIVES We aimed to simultaneously evaluate health benefits and risks associated with different types of greenness in children, in terms of...

The future of biodiversity hinges partly on realizing the potentially high conservation value of human-dominated countryside. The characteristics of the countryside that promote biodiversity preservation remain poorly understood, however, particularly at the fine scales at which individual farmers tend to make land use decisions. To address this problem, we explored the use of a rapid remote se...

The effects of land use and land use change on stream nitrate are poorly understood. While case studies have been presented, most process work has been done in areas with one land use (minimally disturbed or agricultural) and areas with substantial atmospheric deposition. In this paper we present results from three neighboring headwater catchments in western Oregon with similar (low) atmospheri...

introduction due to the proximity to the sea, beaches always attracted tourists. on the other hand the coastal ecosystems are the most important and sensitive dual nature (land, naval), and variety of animal species are within themselves. the most important (and also longest) coastal area in iran are persian gulf and gulf of oman in south with about 2530km long and caspian sea in north with abo...

NOVOTNY, KRISTEN ELISE. Mammalian Nest Predators Respond to Greenway Width, Habitat Structure, and Landscape Context. (Under the direction of George R. Hess.) Birds of conservation concern breed in suburban greenways, yet abundant populations of mammals that depredate bird nests may compromise nest success. We evaluated how three factors influenced total mammalian nest predator abundance and in...

nowadays, with the development of human societies and more mastery over the environment, to environmental changes caused by the faster and wider than before the occurrence of the joins. so having the necessary information about these changes and to manage the natural order is essential to sustainable ecosystems, metrics of landscape is tools landscape situation are few mechanisms that cause the...

This paper deals with the concept of “residential models” and the role it plays on human relations in residential complexes. It intends to; review the concept of residence; understand how a residential model takes form; the influence of a residential model on future human interactions. To this end, having reviewed comments and viewpoints, focused on “what is residence? which factors may create ...
