The analysis of the dependence of landscape patterns on environment was carried out in order to investigate the landscape structure evolution of Spain. The underlying concept was that the dependence between landscape spatial structure and environmental factors could be gradually decreasing over time. Land cover data were recorded from aerial photo interpretation of 206 4 × 4 km samples from thr...
Rapid urbanization has accelerated land use and land cover changes, and generated the urban heat island effect (UHI). Previous studies have reported positive effects of neighborhood landscapes on mitigating urban surface temperatures. However, the influence of neighborhood landscape spatial patterns on enhancing cooling effects has not yet been fully investigated. The main objective of this stu...
Geographic information systems (GIS) are increasingly being used in environmental impact assessments (EIA) because GIS is useful for analysing spatial impacts of various development scenarios. Spatially representing these impacts provides another tool for landscape ecology in environmental and geographical investigations by facilitating analysis of the effects of landscape pattern on ecological...
Adverse changes in rangeland vegetation can be considered as one of the criteria for land degradation. Some of these changes can be evaluated through monitoring the spatial changes of landscape parameters. This study aimed to investigate the landscape changes in Kezab rangelands of Yazd province, central Iran. Landsat satellite images of 1990, 2002, and 2013, and landscape metrics including Tot...
BACKGROUND Malaria, caused by the parasite Plasmodium falciparum, is a significant source of morbidity and mortality in southern Zambia. In the Mapanza Chiefdom, where transmission is seasonal, Anopheles arabiensis is the dominant malaria vector. The ability to predict larval habitats can help focus control measures. METHODS A survey was conducted in March-April 2007, at the end of the rainy ...
A critical issue in landscape ecology is to understand the effects of disturbances on landscape processes. While there is increasing interest in examining the ecological consequences associated with changes in landscape structure and composition, little is known about how soil respiration across landscapes might be affected within this context. We examined field-season soil respiration rates (S...
The variation of landscape metrics caused by varying the map input resolution has been investigated. Landscape metrics are spatial indicators used to link spatial patterns with the ecological processes that generate them. An aerial photograph was semiautomatically classified at different resolutions by superimposing a grid with a variable cell dimension (10, 20 and 40 metres) in a GIS environme...
In English the NP1 V NP2 construction typically involves arguments that are construed as Agent and Patient, or Subject Object. It is associated with notion of transitivity analyzed accordingly, even when it exhibits only syntactic properties but not its semantic characteristics. This phenomenon well-known has been accounted for by linguists (Lakoff 1977; Hopper Thompson 1980, among others) a re...
Land surface temperature (LST) is an important parameter to study in urban climate. The understanding of the influence of biophysical factors could improve the establishment of modeling urban thermal landscape. It is well established that climate hold a great influence on the urban landscape. However, it has been recognize that climate has a low priority in urban planning process, due to the co...
