- T. Tscharntke, Y. Clough, T. Wanger
- Biology
- 1 June 2011
The short-term and long-term ecological benefits of Shade trees in coffee Coffea arabica, C. canephora and cacao Theobroma cacao agroforestry are reviewed and the poorly understood, multifunctional role of shade trees for farmers and conservation alike is emphasized.
What drives elevational patterns of diversity? A test of geometric constraints, climate and species pool effects for pteridophytes on an elevational gradient in Costa Rica
- Jürgen Kluge, M. Kessler, R. Dunn

- 1 July 2006
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 richness.

Elevational gradients in species richness and endemism of selected plant groups in the central Bolivian Andes
- M. Kessler
- Environmental SciencePlant Ecology
- 1 August 2000
Elevational zonation revealed a significant accumulation of upper and lower elevational range boundaries at 900–1050 m and at 1500–1850 M, corresponding to the elevational limits of the main physiognomic vegetation types.

Aim To document the elevational pattern of epiphyte species richness at the local scale in the tropical Andes with a consistent methodology.
Tradeoffs between income, biodiversity, and ecosystem functioning during tropical rainforest conversion and agroforestry intensification

It is concluded that low-shade agroforestry provides the best available compromise between economic forces and ecological needs, and Certification schemes for shade-grown crops may provide a market-based mechanism to slow down current intensification trends.
A global comparative analysis of elevational species richness patterns of ferns

Aim: Elevational gradients offer an outstanding opportunity to assess factors determining patterns of species richness, but along single transects potential explanatory factors often covary, making…
Combining high biodiversity with high yields in tropical agroforests
- Y. Clough, J. Barkmann, T. Tscharntke
- Environmental ScienceProceedings of the National Academy of Sciences
- 2 May 2011
This work integrates biodiversity and crop productivity data for smallholder cacao in Indonesia to exemplify for tropical agroforests that there is little relationship between yield and biodiversity under current management, opening substantial opportunities for wildlife-friendly management.
ESTIMATING SPECIES RICHNESS OF TROPICAL BIRD COMMUNITIES FROM RAPID ASSESSMENT DATA
- S. Herzog, M. Kessler, T. Cahill
- Environmental Science
- 1 July 2002
Abstract Rapid assessment surveys of tropical bird communities are increasingly used to estimate species richness and to determine conservation priorities, but results of different studies are often…
The elevational gradient of Andean plant endemism: varying influences of taxon‐specific traits and topography at different taxonomic levels
- M. Kessler
- Environmental Science, Biology
- 1 September 2002
The aim was to compare the elevational patterns of plant endemism of the entire flora and selected families and genera in a search for commonalities.
