Abstract

The effects of global warming are stronger in high-elevation environments than elsewhere. Here, we review recent advances in alpine plant ecology with a focus on dry mountain ranges, mainly in Mediterranean-type climate, with a global change perspective. Raising temperatures and changes in precipitation influence both plant growth and reproduction, and therefore the spatial distribution of species. Research in high-elevation systems evidenced that plant-plant interactions involving cushion plants play a crucial role in the assembly of plant communities, influencing species richness, genetic and phylogenetic diversity, and species persistence. By buffering environmental extremes and ameliorating biophysical conditions, cushion plant species acting as ecosystem engineers are fundamental in the response of alpine ecosystems to global warming, mitigating negative impacts on different plant species with narrow niche and small distribution range.
Los efectos del calentamiento global son más notables en entornos de gran altitud que en otros ecosistemas. Aquí revisamos avances recientes en ecologiá de plantas alpinas centrándonos en cadenas montanõsas secas, principalmente bajo clima de tipo mediterráneo, y con una perspectiva de cambio global. El aumento de temperatura y los cambios de precipitación influyen tanto en el crecimiento y reproducción de las plantas como en la distribución espacial de las distintas especies. La investigación en sistemas de alta montanã ha puesto de manifiesto que las interacciones planta-planta implicando plantas cojín desempenañ un papel fundamental en la formación de las comunidades vegetales, influyendo en la riqueza de especies, la diversidad genética y filogenética y la persistencia de las especies. Amortiguando extremos ambientales, algunas especies que actuán como ingenieros del ecosistema, como muchas especies de plantas almohadilladas, pueden ser clave en la respuesta de los ecosistemas alpinos al calentamiento global, mitigando los impactos negativos sobre muchas especies que tienen un nicho limitado y una distribución espacial restringida.
