Elsevier is a world-leading provider of information solutions that enhance the performance of science, health, and technology professionals.
All knowledge begins as uncommon—unrecognized, undervalued, and sometimes unaccepted. But with the right perspective, the uncommon can become the exceptional.
That’s why Elsevier is dedicated to making uncommon knowledge, common—through validation, integration, and connection. Between our carefully-curated information databases, smart social networks, intelligent search tools, and thousands of scholarly books and journals, we have a great responsibility and relentless passion for making information actionable.

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
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).
Land use controls and residential land values in the Offinso South municipality, 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.
Super-resolution image analysis as a means of monitoring bracken (Pteridium aquilinum) distributions
The bracken (Pteridium aquilinum) fern is environmentally significant due to its great abundance and swift colonisation, and its perception as a problem plant in degrading agricultural or ecologically sensitive land. Various attempts have been made to map bracken using remote sensing, but these have proved relatively unsuccessful, often apparently constrained by the lack of spatial detail associated with medium spatial resolution satellite sensors such as the Landsat series. In this study, bracken was characterised using a combination of 30m Landsat sensor imagery and 4m IKONOS imagery.
impact of permanent protection on cost and participation in a conservation programme: A case study from Queensland
Conservation covenants have become a popular tool to protect land in perpetuity. Understanding the impact of a covenant on price and enrolment in a conservation programme can help decision makers plan their interventions more carefully, and judge whether the extra longevity justifies the changed participation rate and cost. This paper uses the case study of a conservation auction in Queensland, Australia, to investigate the influence of a compulsory conservation covenant on bid price and participation.
