Degree of Fragmentation Affects Fish Assemblage Structure in Andros Island (Bahamas) Estuaries (2004, background): “UVC may result in an underestimate of cryptic species (Brock 1982; Ackerman and Bellwood 2000; Willis 2001), highly mobile species (Thresher and Gunn 1986), and other large piscivores (Kulbicki 1998; Willis et al. 2000), but has been used extensively because it is non-destructive, rapid, and simple.”
Underwater video techniques for observing coastal marine biodiversity: A review of sixty years of publications (1952–2012) (2014, background): “…UVC for 33 estimating fish abundance and diversity have been reported and discussed in several papers 34 (Chapman et al., 1974; Sale, 1980; Brock, 1982; Harmelin-Vivien et al., 1985; Watson et al., 35 1995; Thompson and Mapstone, 1997; Willis, 2001; Kulbicki et al., 2010; Dickens et al., 36 2011).”
Spatial prediction of demersal fish distributions: enhancing our understanding of species–environment relationships (2009, background): “However, the majority previous studies have relied upon categorical or linear descriptors of relief (Ebeling et al. 1980, Cole 1994, McCormick 1994, Friedlander & Parrish 1998, Moser et al. 1998, Babcock et al. 1999, Willis 2001, Curley et al. 2002, Westera et al. 2003, Willis & Anderson 2003).”
Trophic structure patterns of Brazilian reef fishes: a latitudinal comparison (2004, background): “A database of relative abundances including 123 species from 33 reef-associated families1 was assembled based on number of individuals per species in UVC.”
The application of predicted habitat models to investigate the spatial ecology of demersal fish assemblages (2010, background): “The majority of studies in the past have relied upon hierarchical classiWcations which combine environmental (including depth) and biological factors into ‘habitat type’ such as reef, seagrass and soft sediment (Ebeling et al. 1980; Cole 1994; McCormick 1994; Moser et al. 1998; Babcock et al. 1999; ”
Differences in fish assemblages from different reef habitats at Hamelin Bay, south-western Australia (2003, background): “However, these guilds of fish are not sampled effectively by direct diver counts, with divers underestimating the abundance of even common species by 40%–60% (Stewart and Beukers 2000; Willis 2001).”
Factors affecting the detection distances of reef fish: implications for visual counts (2011, background): “In particular, visual counts largely underestimate the abundance of cryptic and nocturnal ﬁsh (e.g., Ackerman and Bellwood 2000; Stewart and Beukers 2000; Willis 2001).”
Behaviour of temperate and sub-tropical reef fishes towards a stationary SCUBA diver (2007, background): “…reported that SCUBA divers underestimate the abundance of common species of Labridae (Brock 1982; Watson et al. 2005), cryptic species (Brock 1982; Ackerman and Bellwood 2000; Willis 2001), and large predatory species (Davis and Anderson 1989; Jennings and Polunin 1995; Willis and Babcock 2000).”
Visual censuses of tropical fish aggregations on artificial reefs: slate versus video recording techniques (2005, unknown): “It is likely that the number of type A species that tend to have direct contact with the reef structure itself, and often occupy crevices, holes, or spaces within the reef, is underestimated by underwater visual census techniques, as compared to destructive methods such as rotenone (Letourneur, 1992”
Latitudinal gradients in Atlantic reef fish communities: trophic structure and spatial use patterns (2004, background): “On tropical reefs, relatively sedentary taxa (category 2) such as the labrid genus Halichoeres, haemulids, chaetodontids and serranids form the most diverse group detected by UVC.”
A comparison of two survey methods: differences between underwater visual census and baited remote underwater video (2010, unknown): “In fact, the only way to accurately survey cryptics may be with the application of an ichthyocide (Willis 2001).”
Acoustic fish communities: sound diversity of rocky habitats reflects fish species diversity (2019, background): “…1986 , Williams et al. 2006) or in estimating their sizes (Edgar et al. 2004), (2) inadequate for detecting cryptic, elusive and nocturnal species (Willis 2001, Edgar et al. 2004, Feary et al. 2011) and (3) subject to some logistical constraints (i.e. visibility and time dive-limits related to…”
Community structure of temperate reef fishes in kelp-dominated subtidal habitats of northern Chile (2007, background): “) were not included in the present study since they might be underestimated significantly in visual census data under the scales of the present study (Willis 2001).”
A comparison of temperate reef fish assemblages recorded by three underwater stereo-video techniques (2005, background): “Brock 1982; Ackerman and Bellwood 2000; Willis 2001 ).”
