Dear colleagues, We are happy to start 2026 by announcing the publication of a new book: 'The Evolution of Cetacean Societies'. https://press.uchicago.edu/ucp/books/book/chicago/E/bo257312594.html The book is inspired by, and built upon the foundations of, Cetacean Societies: Field Studies of Dolphins and Whales, published in 2000, and edited by Janet Mann, Richard C. Connor, Peter Tyack, and Hal Whitehead, who contribute to chapters in this new volume. The Evolution of Cetacean Societies provides a comprehensive overview of the significant advancements made in studying cetacean behavior and ecology over the last twenty-five years, focusing on our growing understanding of these animals’ complex social lives. Bringing together scientists from multiple disciplines, the volume summarizes key innovations and progress related to studying cetacean societies’ cultural and genetic basis, their complex social structures, their use of cooperation and patterns of social conflict, and their significant interactions with humans. Each chapter provides an in-depth account of the social lives of whales and dolphins, incorporating the latest cutting-edge research from genomics, communication, network analysis, and animal culture to explain how these animals form societies, maintain relationships, and share information. The final chapters focus on the existential threats facing these diverse and charismatic species, how human-cetacean interactions have shaped our perceptions, and what scientists can learn from their diverse social lives by championing researcher diversity in marine mammal science.
