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 …

Background: Tropical high mountains present extreme daily temperature variations, frequent
high air evaporative demands and seasonal differences in soil water availability. Plants …

This review contrasts the frost resistance of plants from the Southern Hemisphere with that of
the Northern Hemisphere and is principally concerned with plants from New Zealand …

A growth form classification for the plants of the Ecuadorian páramos is proposed, consisting
of ten forms: stem rosettes, basal rosettes, tussocks, acaulescent rosettes, cushions and …

Summer frost resistance and ice nucleation temperatures for 33 alpine plant species were
measured in situ to avoid the shortcomings of laboratory tests. Species were selected to …

Freezing tolerance and avoidance were studied in several different sized species of the
tropical high Andes (4200 m) to determine whether there was a relationship between plant …

Páramos are exceptionally species‐rich tropical alpine ecosystems that provide several
important ecosystem services, including carbon storage and water provision. The responses …

If snow cover in alpine environments were reduced through climatic warming, plants that are
normally protected by snow-lie in winter would become exposed to greater extremes of …

Freezing resistance through avoidance or tolerance of extracellular ice nucleation is
important for plant survival in habitats with frequent subzero temperatures. However, the role …

It is likely that Polylepis (Rosaceae) occurs naturally at higher elevations than any other
arborescent angiosperm genus in the world. The 15 species (Simpson 1979) are confined to …
