Ecoandes-Studies on Tropical Andean Ecosystems
Estudios de Ecosystemas Tropandinos

Ecoandes is a book series which documents the ecology along several transects across the Colombian Andes. The seven book volumes published in this series are the splendid and careful documentation of the legendary Dutch-Colombian ECOANDES expeditions in the three cordilleras of the Andes in Central Colombia (1980-1983) and in the Sierra Nevada de Santa Marta (1977) of Studies on Tropical Andean Ecosystems and were edited by Thomas van der Hammen, who led five of the seven expeditions.
Publication language is Spanish, with some english language papers.

The contributions in the volumes compile an inventory of key components of the different tropical Andean ecosystems along the altitudinal gradient encompassing dry forests, montane rain forests and páramos with their species content of woody and herbaceous vascular plants (according to the vegetation layering), bryophytes, lichens and macroscopic fungi. Further soil fauna (including many new species of worms) and the abiotic characteristics of soils, geomorphology, geology and the driving factor the equatorial wet climate are considered in the study.

The expeditions performed stratified sampling at altitudinal intervals of 200 m along the seven altitudinal gradients studied. The páramos was also sampled at shorter intervals, because of its azonal vegetation of cushion and Sphagnum bogs, mire and glacial lake vegetation.

Volume 2, 6 and 7 deal respectively the Sierra Nevada de Santa Marta, world?s highest coastal mountain, Tatamá and Sumapaz transect studies, the remaining volumes document the Parque Los Nevados transect in the Central Cordillera. The six available Ecoandes volumes series sum up to a total of 4678 pages. The individual volumes of the series are profusely illustrated with a total of 1031 figures, 568 photographs and 402 tables.

Since the publication of the classic first volume (now long out of print) on the natural vegetation of Colombia by the late Dr. José Cuatrecasas in 1934 and 1958, the Ecoandes volumes are, almost 50 years later, a second comprehensive contribution to understanding the extremely diverse ecosystems of the Colombian Andes.
