The impact on nitrogen (N) and phosphorus (P) cycles of human activity is a growing
concern and has several causes and consequences (MacDonald et al., 2011; Peñuelas et …

Climatologists tell us that Earth's climate is changing (1): It currently seems clear that a
warmer climate is develo** in the northern hemisphere, and that the weather will become …

A significant increase in reactive nitrogen (N) added to terrestrial ecosystems through
agricultural fertilization or atmospheric deposition is considered to be one of the most …

Global mean temperature is predicted to increase by 2–7° C and precipitation to change
across the globe by the end of this century. To quantify climate effects on ecosystem …

Generations of plant scientists have been fascinated by alpine plant life-with the exposure of
organisms to dramatic climatic gradients over a very short distance. This comprehensive text …

The amplified “greenhouse effect” associated with increasing concentrations of greenhouse
gases has increased atmospheric temperature by 1° C since industrialization (around 1750) …

Earlier spring phenology observed in many plant species in recent decades provides
compelling evidence that species are already responding to the rising global temperatures …

Growing concern about the influence of climate change on flowering plants, pollinators, and
the mutualistic interactions between them has led to a recent surge in research. Much of this …

Global nitrogen (N) enrichment and changing precipitation regimes are likely to alter plant
community structure and composition, with consequent influences on biodiversity and …

We integrated experimental and natural gradient field methods to investigate effects of
climate change and variability on flowering phenology of 11 subalpine meadow shrub, forb …
