Abstract
Purpose
The purpose of this study is to evaluate the vulnerability of the important rangeland shrub, Atriplex leucoclada (Boiss) to both climate change and livestock grazing, within the Syrian rangelands as a representative landscape type of West Asia.
Design/methodology/approach
Ecologically based quantitative niche models were developed for both shrub species using maximum entropy and 13 spatially explicit GIS-based layers to predict current and future species distribution scenarios. Climatic variables varied over time in line with the predictions created from the HADCM3 global circulation model.
Findings
Results indicate that with grazing and climate change, the distribution of A. leucoclada will be reduced by 54 per cent in 2050, with the mean annual and minimum temperatures of the coldest month having the highest contribution in the model (28.7 and 21.2 per cent, respectively). The contribution of the grazing pressure, expressed by the overgrazing index, was estimated at 8.2 per cent.
Originality/value
These results suggest that the interaction of climate and increased grazing has the potential to favor the establishment of unpalatable species, while reducing the distribution of preferred plant species on western Asia rangelands.

Abstract
Entrepreneurial profits flow from differences in expectations between buyers and sellers regarding the future value of resources. This article investigates whether differences in expectations can be influenced by an entrepreneur to produce greater profits. It is argued that there are several points in the entrepreneurial process where such interventions can occur and that the use of these techniques should be associated with superior wealth creation. The article also explores the ethical implications of influencing stakeholders in this way.

Abstract
The academic community is more fully integrating technology into the business it conducts. Online courses are becoming more and more popular. Popular culture can be a source of commonality among students that can be used to more effectively teach leadership in an online environment. This manuscript outlines the use of a group book review assignment to teach leadership while simultaneously fostering a sense of community among students learning about leadership in a primarily asynchronous environment.
