Male and female bottlenose dolphins Tursiops spp. have different strategies to avoid interactions with tour boats in Doubtful Sound, New Zealand (2003, background): “I calculated this non-significant threshold for the present dataset and discarded samples shorter than this threshold (Williams et al. 2002).”
Tourism affects the behavioural budget of the common dolphin Delphinus sp. in the Hauraki Gulf, New Zealand (2008, background): “…horizontal avoidance, increase in speed and decrease in resting behaviour (Gordon et al. 1992, Corkeron 1995, Barr & Slooten 1999, Bejder et al. 1999, Scarpaci et al. 2000, Williams et al. 2002, Lusseau 2003b, Constantine et al. 2004, Bejder et al. 2006b, Neumann & Orams 2006, Richter et al. 2006).”
Disturbance to a foraging seabird by sea-based tourism: Implications for reserve management in marine protected areas (2011, background): “Reduction of natural conservation values in the marine environment due to nature-based tourism and recreation, has been reported for sea-based activities (McCrone, 2001; Williams et al., 2002).”
Global economic value of shark ecotourism: implications for conservation (2013, background): “There are concerns regarding potential ecological impacts of ecotourism because of direct and indirect disturbance to organisms and habitat, including noise pollution (Williams et al., 2002) and damage to coral reefs (Davis & Tisdell, 1995).”
The Negative Impacts of Whale-Watching (2012, unknown): “Killer whale, Orcinus orca [43, 58, 61]”
Effects of provisioning ecotourism activity on the behaviour of white sharks Carcharodon carcharias (2007, background): “For example, animals being observed might perceive benign human presence as a predation risk (e.g. Burger & Gochfeld 1998, Williams et al. 2002, McClung et al. 2004, Nevin & Gilbert 2005).”
Behavioural changes in female Indo-Pacific bottlenose dolphins in response to boat-based tourism (2007, background): “The impact of dolphin watching activity and boat traffic on dolphins has been studied at several locations around the world (Wells & Scott 1997, Bejder et al. 1999, Constantine 2001, Williams et al. 2002, Hastie et al. 2003, Lusseau 2003a,b, 2004, Scarpaci et al. 2003).”
The Effects of Ship Noise on Marine Mammals—A Review (2019, background): “…1 µ Pa rms (0.01–50 kHz), and the Lombard eﬀect (i.e., increased source level and vocalization duration) has been reported in ship noise levels above 98 dB re 1 µ Pa rms (1–40 kHz) (Foote et al., 2004; Holt et al., 2009, 2011; Lusseau et al., 2009; Noren et al., 2009; Williams et al., 2002, 2014).”
Swimming speed, respiration rate, and estimated cost of transport in adult killer whales (2009, methodology): “Previous analyses have shown that measurements recorded (and consequently swimming speeds inferred) by the theodolite used in this study were accurate to within ±3.5% at a distance of approximately 4 km from the observation cliff (Williams et al. 2002).”
Response of travelling bottlenose dolphins (Tursiops aduncus) to experimental approaches by a powerboat in Jervis Bay, New South Wales, Australia (2006, background): “…vertical avoidance, such as increasing their dive duration, or adopting horizontal avoidance by changing their swimming direction, for example killer whales, Orcinus orca, exposed to approaches by a boat adopted a less predictable path than when no vessels were present (Williams et al., 2002).”
