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

Christian Körner has been at the forefront of research investigating treelines, and in the late
1990s and early 2000s he proposed a unifying theory to explain the global occurrence of …

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 …

Many species face increasing drought under climate change. Plasticity has been predicted
to strongly influence species' drought responses, but broad patterns in plasticity have not …

Low temperature represents, together with drought and salt stress, one of the most important
environmental constraints limiting the pro ductivity and the distribution of plants on the Earth …

The previous chapters have provided a first insight into the heterogeneity, complexity and
great physiognomic and ecological variety of the timberline phenomenon; a heterogeneity …

1. Introducción a Sierra Andina Ecuatoriana es una zona muy diversa en cuanto a

The physiological traits associated with water relations of eight common epiphytic ferns in a
Mexican cloud forest were investigated in relation to the distribution of these species within …

Atmospheric conditions are expected to become warmer and drier in the future, but little is
known about how evaporative demand influences forest structure and function …
