Plot-scale evidence of tundra vegetation change and links to recent summer warming.

Temperature is increasing at unprecedented rates across most of the tundra biome. Remote-sensing data indicate that contemporary climate warming has already resulted in increased productivity over much of the Arctic, but plot-based evidence for vegetation transformation is not widespread. We analysed change in tundra vegetation surveyed between 1980 and 2010 in 158 plant communities spread across 46 locations. We found biome-wide trends of increased height of the plant canopy and maximum observed plant height for most vascular growth forms; increased abundance of litter; increased abundance of evergreen, low-growing and tall shrubs; and decreased abundance of bare ground. Intersite comparisons indicated an association between the degree of summer warming and change in vascular plant abundance, with shrubs, forbs and rushes increasing with warming. However, the association was dependent on the climate zone, the moisture regime and the presence of permafrost. Our data provide plot-scale evidence linking changes in vascular plant abundance to local summer warming in widely dispersed tundra locations across the globe. © 2012 Macmillan Publishers Limited.

Supply Chain Relationships for Customer Satisfaction in China: Interdependence and Cooperative Goals

This study develops a model based on Deutsch’s theory of cooperation and competition to clarify the supply chain relationships and interactions that contribute to customer satisfaction. Results of structural equation analyses suggest that organizations and suppliers and organizations and distributors who recognize each other’s importance develop cooperative rather than competitive and independent goals. With cooperative goals, they come to trust each other and work for continuous improvement; these relationships in turn result in the products and service that satisfy customers. Results were interpreted as suggesting that cooperative goals are an important basis for developing effective supply chain partnerships in Asia and perhaps in other regions as well.
