A Sex‐Specific Affiliative Contact Behavior in Indian Ocean Bottlenose Dolphins, Tursiops sp. (2006, background): “The abundance of large sharks and shark bite scars on the dolphins suggests that predators exert some influence on group and bond formation in both sexes (Connor et al. 2000a; Heithaus 2001).”
Scarring patterns and relative mortality rates of Indian Ocean whale sharks (2008, background): “Analysis of scarring patterns may thus provide an insight into the relative importance and source of mortality afflicting whale sharks, as is the case for other large marine species such as manta rays (Mobulinae), manatees, whales, dolphins and seals (Kraus, 1990; Hiruki et al., 1993; Angliss & DeMa”
Does tiger shark predation risk influence foraging habitat use by bottlenose dolphins at multiple spatial scales (2006, background): “E; Heithaus 2001d).”
Male dolphin alliances in Shark Bay: changing perspectives in a 30-year study (2015, background): “Over 70% of the dolphins have shark bite scars (Heithaus, 2001), although researchers have never witnessed an attack (but did observe a flight reponse; Connor & Heithaus, 1996).”
Habitat use and foraging behavior of tiger sharks (Galeocerdo cuvier) in a seagrass ecosystem (2002, methodology): “Comparisons of catch rates among habitats cannot provide an accurate measure of shark habitat use due to dierential bait loss and possible dierences in catch radii among habitats (Heithaus 2001a).”
FOOD AVAILABILITY AND TIGER SHARK PREDATION RISK INFLUENCE BOTTLENOSE DOLPHIN HABITAT USE (2002, methodology): “…were defined based on both changes in water temperature and in the abundance of many species that, along with dolphins, are prey of tiger sharks; these include dugongs (Dugung dugon), turtles (Caretta caretta and Chelonia mydas), and sea snakes (primarily Hydrophis elegans) (Heithaus 2001c).”
Parallel influence of climate on the behaviour of Pacific killer whales and Atlantic bottlenose dolphins (2004, background): “…of predation has ever been recorded in either population; living individuals do not bear scars from bites, or have dead stranded animals been observed with bite marks as in other locations where shark and killer whale predation occur (Heithaus 2001; Heithaus & Dill 2002; Naessig & Lanyon 2004).”
Surviving at sea: ecological and behavioural predictors of calf mortality in Indian Ocean bottlenose dolphins, Tursiops sp. (2005, unknown): “2% of juvenile and adult dolphins (Heithaus 2001).”
The ecological importance of intact top-predator populations: a synthesis of 15 years of research in a seagrass ecosystem (2012, background): “…the proportion of foragers in a habitat divided by the portion of food resources in a habitat) should increase in safer habitats and decrease in dangerous habitats as the overall risk of predation increases (e.g. Abrahams and Dill 1989, Hugie and Dill 1994, Heithaus 2001c, Křivan et al. 2008).”
THE USE OF NATURAL MARKINGS IN STUDIES OF LONG‐FINNED PILOT WHALES (GLOBICEPHALA MELAS) (2007, background): “In addition to aiding in identification, natural marks can serve to indicate characteristics of the population such as disease prevalence (Thompson and Hammond 1992; Wilson et al. 2000), predation pressure (Heithaus 2001), and intraspecific interactions (MacLeod 1998; Scott et al. 2005).”
Characteristics of a manta ray Manta alfredi population off Maui, Hawaii, and implications for management (2011, background): “%) had an injury that appeared to have been caused by a shark attack based on wound characteristics described for shark predation on marine mammals and turtles (Corkeron et al. 1987, Heithaus 2001, Heithaus et al. 2002).”
The size, composition and function of wild bottlenose dolphin (Tursiops sp.) mother–calf groups in Shark Bay, Australia (2008, background): “calf groupsize tends tobe smallerwhenpredation risk ishigh in the warm months than when predation risk is low in cooler months (Mann&Watson-Capps 2005), even though 34% of calves (Mann&Barnett 1999) and 74% of noncalves in Shark Bay have shark bite scars (Heithaus 2001).”
Ecology and conservation of common bottlenose dolphins Tursiops truncatus in the Mediterranean Sea (2009, background): “…mortality of bottlenose dolphins (Tursiops spp.) and other small cetaceans in several areas around the world (e.g. in Australia: Corkeron, Morris & Bryden, 1987; Mann & Barnett, 1999; Heithaus, 2001; in the south-eastern United States: Wood, Caldwell & Caldwell, 1970; Wells, Scott & Irvine, 1987).”
Habitat selection in a coastal dolphin species (Cephalorhynchus hectori) (2003, background): “In various bottlenose dolphin populations in Australia and Florida, 31–74% of the individuals bear bite scars indicating high predation pressures by sharks (Corkeron et al. 1987; Urian et al. 1998; Heithaus 2001b ).”
Aggression in bottlenose dolphins: Evidence for sexual coercion, male-male competition, and female tolerance through analysis of tooth-rake marks and behaviour (2005, unknown): “Other forms of intra-specific aggression, such as body slamming and ramming with the rostrum, would result in more lethal internal damage (Connor et al., 2000b), but we are not likely to find dead animals given the uninhabited coastline and high density of sharks ( Heithaus, 2001a, b).
