Building Development and Roads: Implications for the Distribution of Stone Curlews across the Brecks
BACKGROUND Substantial new housing and infrastructure development planned within England has the potential to conflict with the nature conservation interests of protected sites. The Breckland area of eastern England (the Brecks) is designated as a Special Protection Area for a number of bird species, including the stone curlew (for which it holds more than 60% of the UK total population). We ex...
Determining Effective Factors on Forest Fire Using the Compound of Multivariate Adaptive Regression Spline and Genetic Algorithm, a Case Study: Golestan, Iran Pahlavani, P., Assistant professor at School of Surveying and Geospatial Engineering, College of Engineering, University of Tehran Raei, A., PhD Candidate of GIS at School of Surveying and Geospatial Engineering, College of Engineeri...
Automatic man-made objects detection from aerial and satellite images be a very important research field to understand the changes in our environment and gives an important source of information to be used in many fields as an infrastructure, mapping generation, planning traffics and cartographic. This study describes and evaluates an automated method for roads extraction and mapping. For roads...
there are technical and theoretical knowledge of the gully, ditch the clean areas on topographic maps and digital models that will help. however, the ability to use maps (dem) to identify the location and frequency of gully requires knowledge about the process of creating a moat.the present study modeled gulliation prone areas in dyreh river basin done. materials and methods used in this resear...
Prevention and estimation of soil erosion from forest roads requires an understanding of how road design and maintenance affect sediment production. Seventyfour plots were installed on forest roads in the Oregon Coast Range to examine the relationship between sediment production and road attributes such as distance between culverts, road slope, soil texture, and cutslope height. An additional c...
Today there is consensus concerning the road traffic's role as a metal source. However, there are so far only a few studies which focus on the road side immission patterns regarding distance from roads, and especially in combination with the leachability of heavy metals down the soil profile. In this study, the aim was to analyse concentrations of traffic related metals in road side soils, at d...

BACKGROUND Road Traffic Crashes (RTCs) are major causes of morbidity and mortality in Nigeria. Few studies in Ibadan have focused on the distribution and determinants of RTC among long distance drivers. OBJECTIVE To describe the distribution of crashes by place, times of occurrence, characteristics of persons involved and identify associated factors. METHODS A cross-sectional study was carr...
10 We examined the impact of the urban environment on the spatial and temporal activity of brood parasitic Brown-headed Cowbirds (Molothrus ater) in Boulder County, CO, USA. We found that cowbirds used the urban areas for foraging and roosting and traveled into the 3240 ha wildland preserve of ponderosa pine in the mornings to parasitize songbird hosts. Cowbird abundance decreased with distance...
lead as non-essential metal, is known the source of toxicity and impacts on the environment and humans. the goal of recent paper is to determine the pb concentration of road and road margin dust of ghamishlu wildlife refuge in isfahan province with an area about 120,000 hectares surrounded by four main roads. traffic load in the southern freeway have been reported as about 3600-19000 cars/day. ...
