• Estimating survival and abundance in a bottlenose dolphin population taking into account transience and temporary emigration (2009, unknown): “Errors in the identification of individuals leading to violation of the first assumption may result from poor quality of photographs used, indistinctiveness of individual markings and instability of markings through time (Hammond 1986, Stevick et al. 2001).”
• Investigating the viability of photo-identification as an objective tool to study endangered sea turtle populations (2008, background): “Hence, the accumulation of errors over time in our database, leading to over or under estimations of population size (Stevick et al., 2001), is likely to be negligible.”
• Scarring patterns and relative mortality rates of Indian Ocean whale sharks (2008, background): “…population trends and estimate demographic rates (Fujiwara & Caswell, 2001; # 2008 The Authors Journal compilation # 2008 The Fisheries Society of the British Isles, Journal of Fish Biology 2008, 72, 1488–1503 Stevick et al., 2001; Bradshaw et al., 2003;Meekan et al., 2006; Speed et al., 2007).”
• Size and structure of a photographically identified population of manta rays Manta alfredi in southern Mozambique (2011, methodology): “Photo-identification (photo-ID) has become an increasingly common and accepted technique, with several aquatic studies having confirmed its accuracy as a research tool (Wu ¨rsig and Jefferson 1990; Stevick et al. 2001; Auger-Methe and Whitehead 2007).”
• North Atlantic humpback whale abundance and rate of increase four decades after protection from whaling (2003, methodology): “This correction is stratified by the distribution of photographic quality in the sample and the quality-specific error rates determined from comparison with genetic tagging (Stevick et al. 2001).”
• Monitoring cetaceans in European waters (2004, methodology): “Stevick et al. (2001) used genetic identity (Palsbøll et al., 1997) as a control in a double-marking experiment to estimate the rate of missed photographic matches in humpback whales and developed a method to use this information to correct population estimates.”
