• TOWARDS RELIABLE BIRD SURVEYS: ACCOUNTING FOR INDIVIDUALS PRESENT BUT NOT DETECTED (2002, background): “The double-observer approach assumes that observer counts are independent and the probability of each observer recording a bird is the same regardless of primary or secondary role (Pollock and Kendall 1987).”
• Using habitat models to identify suitable sites for marine protected areas for harbour porpoises (Phocoena phocoena) (2010, background): “Harbour porpoises have been shown to respond to survey vessels by moving away from them (Palka and Hammond, 2001).”

• Design and field methods for sighting surveys of cetaceans in coastal and riverine habitats (2008, background): “Observed densities may be artificially lowered by avoidance (e.g. harbour porpoise, Palka & Hammond, 2001) or raised by attraction (Dall’s porpoise Phocoenides dalli, Turnock, Buckland & Boucher, 1995; Hector’s dolphins, Dawson et al., 2004).”
