Global warming has greatly stimulated vegetation growth through both extending the growing season and promoting photosynthesis in the Northern Hemisphere (NH). Analyzing the combined dynamics of such trends can potentially improve our current understanding on changes in vegetation functioning and the complex relationship between anthropogenic and climatic drivers. This study aims to analyze the...

The use of modern crop varieties is a dominant method of obtaining high yields in crop production. Efforts to identify suitable varieties, with characteristics that would increase crop yield under future climate conditions, remain essential to developing sustainable agriculture and food security. This work aims to evaluate potential genotypic adaptations (i.e., using varieties with increased ab...

This article empirically investigates the role of organizational structure in the transformational leadership (TFL) process. We examine organizational centralization, formalization, and size as antecedents of an organization's TFL climate, and as moderators of the relationship between TFL climate and productive organizational energy (POE). Hypotheses are tested using a sample of 125 organizatio...

The extinction of a species is inevitably preceded by the extirpation of a series of local populations. Ecological theory predicts that vulnerability to extirpation varies between populations and is ultimately linked to environmental heterogeneity. If populations of a species are present in multiple regions separated by abrupt changes in environmental conditions (e.g., biomes), spatial variatio...

The Convention on Biological Diversity’s (CBD) VIth Conference of the Parties (COP) and the World Summit on Sustainable Development agreed to a target to achieve a significant reduction of the rate of biodiversity loss by 2010. The VIIth COP adopted a conceptual framework to facilitate the assessment of global progress toward 2010 and to encourage national and regional targets and indicators. H...

Events of regional-scale vegetation mortality appear to be increasing in a variety of biomes throughout the Earth and are frequently associated with increased temperatures, droughts, and often (but not always) with outbreaks of biotic agents such as insects and pathogens (for review, see Allen et al., 2010; Supplemental Information S1). The precise physiological mechanisms underlying plant mort...

Groundwater contamination due to saltwater intrusion (SWI) has an extreme effect on freshwater quality. Analytical and numerical models could be used investigate SWI. This study aims develop analytical solution SWI into coastal aquifers which was applied a real case at the Middle Nile Delta aquifer (MNDA). The presented new formula predict difference in depth of seawater interface change bounda...

© The Ecological Society of America www.frontiersinecology.org C interiors have biome boundaries that are highly sensitive to climate change. The northern prairie–forest biome border in central North America is such a case; it is ~2700 km in length, extending from northern Alberta, Canada, southeastward across the Canadian prairie provinces, and into the western Great Lakes region of the US (De...
