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 …

Aim At a coarse scale, the treelines of the world's mountains seem to follow a common
isotherm, but the evidence for this has been indirect so far. Here we aim at underpinning this …

Little is known about how soil properties control tree growth at its upper limit. This paper
reviews the state of knowledge and discusses the results specifically related to ecozones, to …

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

Aim To document the elevational pattern of epiphyte species richness at the local scale in
the tropical Andes with a consistent methodology. Location The northern Bolivian Andes at …

Alpine treeline ecotones can be gradual transitions, abrupt boundaries, or patchy mosaics,
and these different patterns may indicate important processes and dynamic properties. We …

 Abstract We present a monograph of the high Andean tree genus Polylepis (Rosaceae),
based on a species concept considering morphological, climatic and biogeographic …

We studied tree height in stands of high-Andean Polylepis forests in two cordilleras near
Cuzco (Peru) with respect to variations in human impact and climatic conditions, and …

C. Trolls Konzepte der" asymmetrischen Verteilung der immerfeuchten Vegetationstypen der
Erde" von 1948 und der" Höhenstufen tropischer Gebirge in vergleichender Sicht" von 1959 …

We studied Polylepis forests along an elevational transect between 3,650 and 4,050 m asl at
the treeline of the moist eastern cordillera in Bolivia to examine changes in above-and …
