I will be lecturing a 4-week workshop on beta-diversity and MultiVariate
Analysis (MVA) Techniques (PCA, CLUSTER, MDS) at the University of
Chetumal (Quintana Roo, Yucatan Peninsula, Mexico) in November-
The course will be made up of daily sessions having both a theoretical
presentation and a practical exercise. The practical exercise will consist
of applying various analytical tools for each MVA technique ON THE
BASIS OF DIFFERENT DATA SETS FROM PUBLISHED PAPERS. As
all of the course participants will be related to TROPICAL SCIENCE,
those data sets MUST deal with topics within such area, ideally covering
botany, zoology or microbiology research into terrestrial, riverine and
marine habitats. Environmental analyses (abiotic parameters) are also
I would like to enquiry whether some of you could possibly lend me a
DATA SET in which any of the following techniques had been used:
1/ Covariance-based Principal Component Analysis (PCA).
2/ Correlation-based Principal Component Analysis (PCA).
3/ Agglomerative clustering by samples, if possible using Bray-Curtis,
Camberra, Manhattan, Euclidean or Correlation diversity indexes (CLUSTER
4/ Aglomerative clustering by species (inverse analysis) (CLUSTER ANALYSIS).
5/ Non-parametrical Multidimensional Scaling (MDS) and the ANOSIM test.
6/ Non-parametrical Multidimensional Scaling (MDS) and the SIMPER test.
THE COURSE WILL RESULT IN A (SPANISH-WRITTEN) MANUAL IN
WHICH ALL CONTRIBUTORS WILL BE APPROPRIATELY
Any further information you may require about the course, please do not
hesitate to contact either me or my counterpart at the University of
Chetumal: Dr Manuel Elías-Gutiérrez (Postgraduate Coordinator:

Thanks for your help in advance.
Looking forward to hearing from you.
