We review the ecological consequences of N deposition on the five Mediterranean regions
of the world. Seasonality of precipitation and fires regulate the N cycle in these water-limited …

Anthropogenic nutrient enrichment and shifts in herbivory can lead to dramatic changes in
the composition and diversity of aboveground plant communities. In turn, this can alter seed …

Nitrogen (N) pollution is a global threat to the biodiversity of many plant communities, but its
impacts on grassland soil seed banks are unknown. Here we show that size and richness of …

Vegetation‐type conversions between grasslands and shrublands have occurred worldwide
in semiarid regions over the last 150 years. Areas once covered by drought‐deciduous …

Disturbances to biocrusts may occur either due to human activities or natural forces. Many of
the human activities that are most likely to result in biocrust disturbance are linked to …

A wide range of studies show global environmental change will profoundly affect the
structure, function, and dynamics of terrestrial ecosystems. The research synthesized here …

Soil seed banks represent reservoirs of diversity in the soil that may increase resilience of
communities to global changes. Two global change factors that can dramatically alter the …

Aims Diverse practices related to livestock intensification often have a deep impact on
grassland diversity. Moreover, alternative degraded states that are hardly reversible can be …

Aims Nitrogen (N) deposition and drought are major drivers of global change that will
influence plant-soil feedbacks. We investigated how N availability, N-impacted soil …

Global biogeochemical cycles have been widely altered due to human activities, potentially
compromising the ability of plants to regulate their metabolism. We grew experimental …
