Dear colleagues:

Many thanks to all the specialists that send me records or information of different cetaceans species. We live far away to any cetaceans species except the dolphins of Madrid zoo to 300 km ;-). Really, this mail list is a very nice example of scientific collaboration. I am greatly surprised. This is not the normal behavior in my country ;-). If somebody need my assistance in any aspect of data analysis that I can do it, please feel free of comment me. At the moment and after of a very intense search in the web, we finally had obtained the following list of species:

Balaena_mysticetus
Balaenoptera_acutorostrata
Balaenoptera_borealis
Balaenoptera_edeni
Balaenoptera_musculus
Balaenoptera_physalus
Berardius bairdii
Berardius_arnuxii
Cephalorhynchus_hectori
Delphinapterus_leucas
Delphinus_delphis
Eschrichtius_robustus
Eubalaena_australis
Eubalaena_glacialis
Eubalaena_japonica
Feresa_attenuata
Globicephala_macrorhynchus
Globicephala_melas
Grampus_griseus
Hyperoodon_ampulatus
Inia_geoffrensis
Kogia_breviceps
Lagenodelphis_hosei
Lagenorhynchus_albirostris
Lagenorhynchus_obliquidens
Lagenorynchus_acutus
Lipotes_vexillifer
Lissodelphis_borealis
Megaptera_novaeangliae
Mesoplodon_densirostris
Monodon_monoceros
Neophocaena_phocaenoides
Orcaella_brevirostris
Orcaella_heinsohni
Orcinus_orca
Pepenocephala_electra
Phocoena_phocoena
Phocoena_sinus
Phocoenoides_dalli
Physeter_macrocephalus
Platanista_gangetica
Pontoporia_blainvillei
Pseudorca_crassidens
Sotalia_fluviatilis
Sousa_chinensis
Stenella_attenuata
Stenella_coeruleoalba
Stenella_frontalis
Stenella_longirotris
Steno_bredanensis
Tursiops_truncatus
Ziphius_cavirostris

If somebody have records of other species the analysis is in course ;-)

Our idea is that students analyze these species using different software packages as seewave (R-environment), audacity, send me the results and I determine a global model using multivariate analysis or artificial neural networks, that are methods more complex for students. The main idea is determining a global pattern of variation in the group. We use this procedure with amphibians and birds in previous practices with curious results. For example, with Spanish species of woodpeckers we found a taxonomic pattern, but with Sylviidae family of birds the differences were due to habitats.... What results can we finally obtain with cetaceans? I don't know but this is very funny ;-) Probably scientifically irrelevant but very funny and specially didactic ;-). Finally we discuss the main tendencies of characteristics of sound communication in the group ;-)

Many regards
