Acknowledgments 



We sincerely thank the fishermen of Vila da Barra do 

 Superagtii and Ilha das Pe^as (Parana coast) for the infor- 

 mation they provided and their help in collecting the inci- 

 dentally caught dolphins. We thank Fundagao O Boticario 

 de Prote^ao a Natureza and the MacArthur Foundation for 

 financial support, and IBAMA/PR, especially Guadalupe 

 Vivekananda, head of the National Park of Superagtii. We 

 also thank Maria Cristina Pinedo, who allowed us to use her 

 laboratory and equipment for the age estimations, and Kesa 

 K. Lehti, who translated the manuscript from Portuguese 

 into English. Renata Ramos and an anonymous referee 

 provided critical and insightful comments on the manu- 

 script. Coordenagao de Pessoal de Nivel Superior (CAPES) 

 provided a fellowship to the senior author This study is part 

 of a dissertation presented by Fernando C. Weber Rosas, sub- 

 mitted in partial fulfillment for a Ph.D. degree in Zoology at 

 the Universidade Federal do Parana, Curitiba, Brazil.
