Background Recent decades have seen a major surge in the study of interspecific variation
in functional traits in comparative plant ecology, as a tool to understanding and predicting …

Mountains, with their isolated position and altitudinal belts, are hotspots of biodiversity. Their
flora and fauna have been observed worldwide since the days of Alexander von Humboldt …

Work toward this book spans almost half a century. I started work on liverworts of Colombia
in 1970–71 during my Ph. D. study at the University of Cincinnati. My advisor, Margaret H …

Tropical montane cloud forests (TMCF) typically experience conditions of frequent to
persistent fog. On the basis of the altitudinal limits between which TMCF generally occur …

Aim Elevational gradients offer an outstanding opportunity to assess factors determining
patterns of species richness, but along single transects potential explanatory factors often …

Predictions about the impacts of climate change on tropical forests require information on
the relative vulnerabilities and roles of the biological components of these unusually …

Aim We studied pteridophyte species richness between 100 m and 3400 m along a
Neotropical elevational gradient and tested competing hypotheses for patterns of species …

Our knowledge about the structure and function of Andean forests at regional scales
remains limited. Current initiatives to study forests over continental or global scales still have …

I analyzed the distribution of Acanthaceae, Araceae, Bromeliaceae, Cactaceae,
Melastomataceae, and Pteridophyta in 62 vegetation plots of 400 m 2 along an elevational …
