Biogeochemical Selectiveness of Cedars Over Metamorphic Rocks of the Escambray Complex, Sancti Spíritus, Cuba/Acknowledgement

I deeply appreciate the help given by the chief-geologist of the studied area of Cumanayagua, eng. Héctor Nuñez Mantilla, during the sampling period. His expertise and knowledge of the geology of the area were very useful for the interpretation of the results.

I also thank the advice given by my friend and college, eng. Orestes Romero Loynaz, and the excellent work preformed by the Laboratory Group of the Enterprise Santa Clara in the processing and analysis of the samples.

Finally, I'll like to thank Andrew Whitworth for his continuous support on helping us editing these books.
