Tiger shark (Galeocerdo cuvier) abundance and growth in a subtropical embayment: evidence from 7 years of standardized fishing effort (2006, background): “1996; Heithaus 2001), that local tiger shark abundance may be characterized by substantial variability as well as seasonal periodicity (e.g., between 1997 and 1999 in Shark Bay, Western Australia, tiger shark numbers consistently peaked during the warm season, September–May; Heithaus 2001; Heithaus ”
Developmental evidence for foraging traditions in wild bottlenose dolphins (2009, background): “…this is a rough measure of habitat use, the study area can be categorized broadly as shallow sea grass banks and deeper areas with little sea grass (Heithaus & Dill 2002), and depth was important in predicting the occurrence of several foraging tactics in previous analyses (Sargeant et al. 2007).”
Can environmental heterogeneity explain individual foraging variation in wild bottlenose dolphins (Tursiops sp.)? (2007, unknown): “This is likely due to a large reduction in the use of shallow seagrass habitats during warm seasons caused by increased predation risk from tiger sharks (Galeocerdo cuvier) in these habitats (Heithaus and Dill 2002), but seasonal shifts in fish community composition (Heithaus 2004) may also be respo”
BEHAVIORALLY MEDIATED INDIRECT INTERACTIONS IN MARINE COMMUNITIES AND THEIR CONSERVATION IMPLICATIONS (2003, background): “In doing so, they give up food but increase their safety (Heithaus and Dill 2002).”
Behavioural drivers of the ecological roles and importance of marine mammals (2015, background): “Resting dolphins are found almost exclusively in safer deeper waters (Heithaus & Dill 2002).”
Predator interactions, mesopredator release and biodiversity conservation. (2009, background): “…predators in two ways, by: (1) changing habitat use in favour of habitats that offer refuge from apex predators (Palomares et al. 1996; Durant 2000; Heithaus & Dill 2002; Mitchell & Banks 2005; Salo et al. 2008; Sergio & Hiraldo 2008); and (2) altering foraging behaviour and activity (Griffen &…”
Does tiger shark predation risk influence foraging habitat use by bottlenose dolphins at multiple spatial scales (2006, methodology): “Fish B/10 cm FL were removed from biomass calculations since they probably represent a relatively small proportion of dolphin diets (Heithaus and Dill 2002).”
Effects of body size, age and maturity stage on diet in a large shark: ecological and applied implications (2008, background): “…have substantial impacts on marine communities through the control they exert on mesoconsumers such as smaller sharks, rays, marine mammals, seabirds and turtles (Lucas and Stobo 2000; Acevedo-Gutiérrez 2002; Heithaus and Dill 2002, 2006; Heithaus 2005; Heithaus et al. 2007; Wirsing et al. 2007).”
Sizing up the ecological role of sharks as predators (2014, background): “…populations with a full age structure consisting of numerous largebodied adults, such as tiger and white sharks, can affect the presence of other species via predation, and suppress species though fear and dominance (e.g. Heithaus & Dill 2002, 2006, Wirsing et al. 2007, Wirsing & Heit haus 2007).”
Assessments of habitat preferences and quality depend on spatial scale and metrics of fitness (2007, background): “Habitat choices determine the acquisition of critical resources such as food (MacArthur, Recher & Cody 1966; Cody 1974; Willson 1974; Rotenberry & Wiens 1998) and refugia from predators (Leber 1985; Martin 1988; Söderström 2001; Heithaus & Dill 2002; Eggers et al .”
Seascapes of fear: evaluating sublethal predator effects experienced and generated by marine mammals (2008, methodology): “Following this framework, Heithaus and Dill (2002) divided the number of foragers in each patch type by habitat-specific levels of fish availability, contrasting the time foraging dolphins allocated to shallow and deep patches during periods of high and low shark abundance.”
The ecological importance of intact top-predator populations: a synthesis of 15 years of research in a seagrass ecosystem (2012, background): “…and up to several kilometres wide) that feature seagrasses along the seaward edges, offshore banks (1–4.5m in depth) largely covered by seagrasses, and waters 6–12m in depth that are primarily covered by sand (see Heithaus and Dill 2002; Vaudo and Heithaus 2009, for more detailed descriptions).”
