ABSTRACT
Mammalogy, European Cetacean Society, Latin American Marine Mammal Society, South American Specialists in Aquatic Mammals, Society of Latin American Specialists in Aquatic Mammals, and many other regional and national societies). There are also many volumes in the marine mammal field which gather and synthesize the data from key papers (e.g. Simmonds and Hutchinson, 1996; Reynolds and Rommel, 1999; Twiss and Reeves, 1999; Mann et al, 2000; Estes et al, 2006; Jefferson et al, 2008; Perrin et al, 2009). The International Whaling Commission (IWC) special volumes on the Cephalorhynchus dolphins, northern hemisphere pilot whales, porpoises and others provide reviews of cetacean status (e.g. Brownell and Donovan, 1988; Donovan et al, 1993; Bjørge and Donovan, 1995). The IUCN Red List website has the latest status list of cetacean species, as well as certain subspecies and populations (see www.redlist.org), with authoritative summaries on abundance, distribution, taxonomy, threats and status, essential for conservation planning. More popular websites can also provide useful supporting information, including the Whale and Dolphin Conservation Society (WDCS) Species Guide (www2.wdcs.org/species/ index.php), marinebio.org (www.marinebio.org), American Cetacean Society (www.acsonline.org) and Wikipedia entries for each species.
