Dear all, My name is Deborah Pinto Fernandes, I am a licensed Biologist and am currently a graduate student at the Universidade Federal do Rio Grande do Norte (UFRN) in Brazil. I am studying to get my masters degree in Psychobiology, with emphasis in Animal Behavior and my advisor is Renata S. Sousa-Lima. As a part of my research I am currently performing a review on the use of acoustic and visual techniques in the study of marine mammal spatial patterns (occurrence, distribution) over the past ten years. I have already made contact with some of you and really appreciate those who have already answered my survey. However, the number of responses was very small and because of this, I am asking everyone here at marmam who work or have worked on any research regarding marine mammal spatial patterns to answer this quick survey regarding information that might have influenced the choice of method used in your research. Let me thank in advance for everyone's attention and contribution and also make myself available for any questions you might have.
