Habitat selection of a large carnivore, the red wolf, in a human-altered landscape

december, 2013
United States of America

Large carnivores, with their expansive home range and resource requirements, are a good model for understanding how animal populations alter habitat selection and use as human densities and development increase. We examined the habitat selection of red wolves (Canis rufus) in North Carolina, USA, where the population of red wolves resides in a mosaic of naturally occurring and human-associated land cover. We used locations from 20 GPS-collared red wolves, monitored over 3years, to develop resource selection functions at the landscape level.

arithmetic method to determine the most suitable planting dates for vegetables

Journal Articles & Books

Saudi Arabia

Optimum crop yield is greatly affected by proper planting and sowing times. The objective of this research was to develop an algorithm that uses the heat unit concept to determine the most suitable planting times for vegetable crops. The developed algorithm was programmed in a database environment with sample climatic data for the Kingdom of Saudi Arabia. The model was tested by validation (comparison to experts’ estimations), verification (statistical comparison to formal published data), and evaluation (by professionals, landowners, and farmers).

Scale and ecological dependence of ecosystem services evaluation: Spatial extension and economic value of freshwater ecosystems in Italy

Journal Articles & Books
december, 2013
Italy

Using land cover datasets derived from satellite imagery as a proxy for ecosystem services (ES) mapping and evaluation generates a series of technical problems mainly related to the resolution at which spatial data are acquired. Small sized and highly fragmented ecosystems such as wetlands, streams and rivers are particularly underestimated when coarse resolution land cover datasets are used.

Reconstruction of contested landscape: Detecting land cover transformation hosting cultural heritage sites from Central India using remote sensing

Journal Articles & Books
december, 2013
India

Central India hosts one of the largest repositories of archaeological sites in the world having a semi-arid climate and distinct eco-geography which is prone to rapid change due to human activities. This paper discusses the changes in land use and land cover for the past twenty-three years in the region altering the rich cultural heritage, revealing by the presence of numerous painted rock-shelter sites in the region. The land cover and land use changes in terms of deforestation, urban growth and development and sandstone mining have been evaluated in the present study.

Land use controls and residential land values in the Offinso South municipality, Ghana

Journal Articles & Books
december, 2013
Ghana

Land use controls may have positive, negative or neutral impact on urban land values. The Offinso South Municipality (OSM) employs conventional zoning in its land management practices. This article investigates the land use control regime in and its impact on land values and the living standards of residents of the municipality. Empirical data were obtained from physical developers in the municipality via self-administered questionnaire. It also collected data from occupiers of amenity lands via guided interviews.
