Dear list: Many months ago I asked on information about sonometry in cetaceans for a research with my students of Environmental Sciences. The idea was to explore the amazing world of cetaceans communication inside the practical classes on Bioacoustic. Traditionally we work in applications of numerical methods in Ecology. This area was new for us but very exciting. Immediately we thought that could be a new idea to develop a comparative analysis of species. Inside the process of understanding cetacean communication the idea of exploring the possible Doppler effect was interesting. My students and me want to give thanks to the people of this list and institutions that give data for developing this activity such as: - NOAA and the web DOSITS (http://www.dosits.org/audio/marinemammals) - Macauly Library of Cornell University (http://macaulaylibrary.org/) - Acoustic laboratory of Oregon and the web Mobysound (http://www.mobysound.org) - Scripps institution and the web Voices in the Sea (http://cetus.ucsd.edu/voicesinthesea.org) Many people had contributed too like Mariana Melcon from Scripps Whale Acoustic Lab, Lorenzo Rojas Bracho from the National Institute of Ecology in Mexico, Jerome Sueur from the Museum of Natural History of Paris and Angelo Farina of Parma University. These excellent researches give useful comments and the paper had been published in the Journal of Experimental Marine Biology and Ecology (http://dx.doi.org/10.1016/j.jembe.2014.02.016). My students are completely crazy by this history that appear in a coffee session of brain-storming of a small group of MENSA of my University. We live to 300 km away from the sea but we are opened to any collaboration that need our knowledge on data analysis. Probably a good idea could be increase the list of species or explore the changes in Doppler shift of one specie in different behavioral activities. The list of species finally studied is: Balaenidae: Balaena mysticetus Eubalaena australis Eubalaena glacialis Eubalaena japonica Balaenoptera acutorostrata Balaenoptera borealis Balaenoptera edeni Balaenoptera musculus Balaenoptera physalus Megaptera novaeangliae Delphinidae: Cephalorhynchus commersonii Cephalorhynchus eutropia Cephalorhynchus heavisidii Cephalorhynchus hectori Delphinus capensis Delphinus delphis Feresa attenuata Globicephala macrorhynchus Globicephala melas Grampus griseus Lagenodelphis hosei Lagenorhynchus acutus Lagenorhynchus albirostris Lagenorhynchus obliquidens Lagenorhynchus obscurus Lissodelphis borealis Orcaella brevirostris Orcaella heinsohni Orcinus orca Pepenocephala electra Pseudorca crassidens Sotalia fluviatilis Sousa chinensis Stenella attenuata Stenella clymene Stenella coeruleoalba Stenella frontalis Stenella longirostris Steno bredanensis Tursiops aduncus Tursiops australis Tursiops truncatus Eschrichtiidae: Eschrichtius robustus Kogiidae: Kogia breviceps Kogia sima Lipotidae: Lipotes vexillifer Monodontidae: Delphinapterus leucas Monodon monoceros Neobalaenidae: Caperea marginata Phocoenidae: Neophocaena phocaenoides Phocoena phocoena Phocoena sinus Phocoenoides dalli Physeteridae: Physeter macrocephalus Platanistidae: Inia geoffrensis Platanista gangetica Pontoporia blainvillei Ziiphidae: Berardius bairdii Berardius arnuxii Hyperoodon ampulatus Indopacetus pacificus Mesoplodon bidens Mesoplodon carlhubbsi Mesoplodon densirostris Mesoplodon europaeus Mesoplodon ginkgodens Mesoplodon hectori Mesoplodon stejnegeri Ziphius cavirostris I hope give thanks personally to the specialists in the next Congress of the European Cetacean Society and I hope to continue learning on this amazing world of cetacean communication.
