Urban Micro Environment and Photosynthesis of Street Trees.

Estimating Height and Diameter Growth of Some Street Trees in Urban Green Spaces

Estimating urban trees growth, especially tree height is very important in urban landscape management. The aim of the study was to predict of tree height base on tree diameter. To achieve this goal, 921 trees from five species were measured in five areas of Mashhad city in 2014. The evaluated trees were ash tree (Fraxinus species), plane tree (Platanus hybrida), white mulberry (Morus alba), ail...

Health and climate related ecosystem services provided by street trees in the urban environment

Urban tree planting initiatives are being actively promoted as a planning tool to enable urban areas to adapt to and mitigate against climate change, enhance urban sustainability and improve human health and well-being. However, opportunities for creating new areas of green space within cities are often limited and tree planting initiatives may be constrained to kerbside locations. At this scal...

Survival and Growth Factors Affecting Community-Planted Urban Street Trees

Urban Warming Drives Insect Pest Abundance on Street Trees

Cities profoundly alter biological communities, favoring some species over others, though the mechanisms that govern these changes are largely unknown. Herbivorous arthropod pests are often more abundant in urban than in rural areas, and urban outbreaks have been attributed to reduced control by predators and parasitoids and to increased susceptibility of stressed urban plants. These hypotheses...

Analysis of Propagation Channel in Urban Street Microcell Environment

In station site selection, i.e., the process of determining locations for installing base stations in mobile communication systems, it is highly advantageous to be able to estimate the propagation loss in a manner that allows accurate modeling of interference from surrounding geographical features and objects on the ground. Moreover, active application of time-space signal processing, represent...
